The importance of a correct central vacuum system



A central vacuum system helps to deliver top notch housekeeping results in a milling facility, according to US firm Kice.

Besides good grain cleaning and dust control, one of the key components that greatly helps in delivering effective housekeeping results in a milling facility is a central vacuum system.

A dust collection system is not the same as a central vacuum system. Typically, dust collection systems have larger air volumes and lower dust loading or handling capabilities, while a central vacuum system operates under lower air volumes but has much higher dust handling capabilities.

From the perspective of Kice, a central vacuum system is a custom-designed network of tubing,  fittings, and elbows, which typically go back to a centrally located baghouse filter and vacuum device (e.g.,  high static fan, multi-stage blower, turbine, or vacuum air power unit).

The central vacuum system provides a high vacuum to the end of a hose with a variety of attachments for cleaning floors, walls, ducts, and around milling and other processing equipment.  The system also moves bulk materials in the event of spillage, equipment cleanout, etc.


In any central vacuum system, there are two important factors that influence its performance. They include:

  • Airflow, which is expressed in cubic feet per minute (cfm).
  • The pressure, more commonly referenced as vacuum, which often is expressed in inches of mercury, inches of water column, or in pounds per square inch (psi).

Special instruments like a manometer or Bourdon gauge can measure this force and express it regarding inches of mercury or water. While the airflow measurement indicates how much air the central vacuum system is moving, the pressure or vacuum measurement indicates the system’s peak draw or force.

Striking a good balance between airflow and vacuum to optimize performance is why sizing and the design of the central vacuum system are so important. A central vacuum system generally will work well if designed and sized properly and has good, high velocity at the tool head, with enough velocity and suction force to pick up and transport the material.

Also, a system will operate more efficiently if there are the correct number of users on the system, and if the system is sealed, grounded properly, and maintained properly. While central vacuum systems have become more commonplace, keeping them operating well and trouble-free can be challenging.

Lack of suction force and too many operators using a system simultaneously may effect and open points such as snaps becoming loose, loose couplings and connection points that cause air leakage may also impact efficiency. Dirty filter bags or vacuum pump inlet filters and a system that is not designed properly can also have a detrimental effect on efficiency.

Essentially, there are three key things that can impact the efficiency and proper functioning of a central vacuum system. They are:

  • Sizing
  • Design
  • Common resistance points


Kice has done extensive testing on various tools (e.g., crevice tool, brush, floor tools), hoses (coiled and uncoiled), and the vacuum air power unit components, including filters, silencers, and check plates at various cfm rates and pressures.

Generally, a system is sized and designed to accommodate the farthest point of pickup and perhaps the worst-case scenario. Sizing a system properly needs to take into account what type of materials it will handle. For example, flour mills and general systems, which handle lighter products and powders in smaller amounts, may be sized to deliver 200 cfm at a vacuum pressure of eight inches of mercury (Hg) per operator.

In contrast, grain elevators, feed mills, and seed facilities, which typically handle heavier products, whole seeds, and larger amounts of denser products, might require 200 cfm at 10 inches of Hg vacuum per operator.

The system also should be sized for realistic conditions. For example, don’t go to extremes on sizing a system for too many operators that may lead to inefficiencies. Oversizing a system leads to excessive horsepower and unnecessary noise.

The distance between the vacuum lines isn’t always super-critical, but like with many mechanical situations, there are limitations. Generally, running multiple three-inch outer diameter (OD) lines as needed throughout the facility is sufficient. Another rule-of-thumb is that the number of pickup locations served by a single three-inch outer diameter header pipeline is not super-critical. However, the critical thing is the number of users on each three-inch OD line.

Kice recommends that a system should have a maximum of two operators/sweepers on a three-inch OD line. With one or two operators, the vacuum suction remains good; however, when more than two operators are using a dedicated line, the suction force will likely start to drop for all the operators.

So, it’s important to design the system to accommodate the appropriate number of operators to avoid overtaxing the system’s capabilities. In sizing a system, a motor horsepower rating that will meet the vacuum relief setting established by the original equipment manufacturer is recommended. This will help minimize the risk of the motor overamping in a closed or clogged situation. When you get a clog in the system or extensive blockage, the vacuum relief valve is going to activate. The vacuum may be high, but the airflow through the relief valve will be minimal.

The end result is that the amps go up, which puts undue strain on the motor. Kice sizes for the release valve setting. In cases where motor overamping occurs, it might be due to the relief valve’s setting being a little too high or the motor’s horsepower a little too low.

For this reason, it’s important not to skimp on the motor’s horsepower rating to serve a given central vacuum system that meets the relief valve setting. Below are some typical horsepower requirements for a system serving a different number of operators.

  • One operator 10-15 hp.
  • Two operators 20-30 hp.
  • Three operators 30-40 hp.
  • Four operators 40-50 hp.
  • Six operators (at the same time) 50-75 hp.

On the other hand, sizing for a four or six-operator system that then only uses one or two operators is wasteful. The vacuum relief valve is pulling in free air to keep the pump safe but uses extra horsepower.


Besides sizing a central vacuum system properly to meet certain performance expectations, it’s also important to keep in mind some of the critical points in the system that may generate resistance and that potentially can reduce efficiency.

Those include:

  • Coiled hoses
  • Overly long hoses that aren’t necessary to fulfil a given task
  • Damaged hoses
  • Damaged tool ends
  • Clogged hoses
  • Large, bulky piles of product that might choke the system
  • Wet or moist product that can create undue resistance points in the system
  • Open snap caps
  • Coupling leaks
  • Dirty filters
  • Open relief valve

In laying out a central vacuum system, it’s important to avoid sharp twists or turns (e.g., mitered elbows) that will hinder the airflow and potentially lead to material buildup and blockage at these critical points.

Any back-to-back 90-degree angles will restrict the system’s pressure.


To help embrace what can impact a system’s efficiency, let’s run through some of the factors that come to bear. What follows is a basic accounting of how things add up when considering a worst-case scenario example with a system that is sized to provide 200 cfm at a pressure of eight inches of Hg. In the worst-case scenario, approximately 2.4 of those eight inches of Hg likely would be accounted for by the baghouse filter with dirty filter bags and the total resistance of the vacuum air power unit with a dirty inlet filter.

Another 2.1 inches of Hg might be accounted for from 25 feet of coiled hose and a crevice tool. So, already at this point more than half – or 4.5 inches of Hg – of a rated design of eight inches of Hg is being tied up due to dirty filter bags, dirty inlet filter, and a coiled-up hose equipped with a crevice tool (the worst-case scenario). Another 1.8 inches of Hg also could be attributed to the resistance created inside the three-inch tubing, elbows, and branch fittings used in a seven-story facility, and that is without moving any dust yet.

So, when adding it all up, out of a total of eight inches of Hg, approximately 6.3 inches of Hg is tied up under this worst-case scenario. This is why design, sizing, and keeping a central vacuum system free from obstructions is critical in moving the maximum amount of material effectively and efficiently.


What can you do to improve performance:

  • Take the time to calculate and understand the vacuum capabilities of the system’s design
  • Remember that a central vacuum system is for cleaning; it’s not meant for large-scale conveying of product.
  • Don’t forget that there will be more suction force closer to the filter.
  • Limit operators to two on each three-inch OD header
  • Reduce restrictions, including the use of more than 25 feet of hose(s)
  • Check for leaks, open caps, and couplings regularly.
  • Do not pull or kink
  • Install a spring cap on each 45-degree elbow, so the hose does not start with a kink from the vertical or horizontal position when picking up piles of product.
  • Allow easy access to air in and around the crevice tool.
  • Verify grounding and continuity of the system.
  • Perform regular maintenance of inlet filters and filter bags.
  • Install branches correctly (e.g., either upward or horizontal, so branch legs do not fill up with material over time).
  • Install cleanout ports at corners and long tubing runs.
  • Have a good complement of tools like crevices (rigid and flexible), gulpers, and bushes to handle various tasks.
  • Consider using static dissipative hose to mitigate static electricity build-up.

Generous donation for Mark Cornwell memorial fund

A campaign to raise money in memory of former colleague Mark Cornwell has received a major cash injection from Tapco Inc.

Mark “Cornman” Cornwell was a long-time associate of the grain and milling industry and having spent many years with World Grain helping build a leading industry magazine he then went on to partner with Perendale Publishers in 2014 to work on Milling and Grain magazine.

He died unexpectedly at his home on 11th September 2017 in Leawood Kansas at the age of 61.

His death left a great big hole in the grain and milling community and it set about fundraising to pay for scholarships.

Milling4Life (M4L) charity engaged with the American Feed Industry Association (AFIA) foundation, the Institute for Feed Education & Research (IFEEDER) to establish the scholarships in perpetuity in Mark’s name.

The scholarships will support students wishing to study feed manufacturing via a variety of learning institution throughout the USA, and Kansas State University course offerings in grain sciences, grain handling and processing which is one of the prominent institutions for scholarship recipients.

A donation of £5,000 from Roger Gilbert of Perendale Publishers Ltd kicked off the fundraising and now Tapco has generously donated £5,000 to the fund.

Paul Taylor of Tapco said: “Here at Tapco Inc. we have built a long, strong relationship with Mark Cornwell and it was a sad day that he was taken from us so soon. His commitment to the grain milling and grain handling sector was globally recognised and he will be sorely missed. Tapco Inc. recognizes the benefits of training young new talent in our industry and as such we wholly endorse this initiative to set up a trust fund in Marks name and in perpetuity for future millers and grain handling engineers.”


M4L is seeking companies in our industry, both within the USA and worldwide, prepared to contribute and who will be recognized for their contribution each time applicants are called upon to take up the scholarships. Individual donations are also welcomed and will be acknowledged via the M4L website  if they wish to be identified.

Tapco is the largest manufacturer of elevated buckets in North America.

NFU backs glyphosate to reduce mycotoxins

The National Farmers Union has spoken about the importance of weedkiller glyphosate in controlling mycotoxins following a landmark ruling in the USA.

Dewayne Johnson, 46, a former groundsman won $289m in damages in a hearing in San Fransisco  after using Monsanto’s Roundup for years.

He developed non-Hodgkins Lymphona and successfully argued that Monsanto’s Roundup had contributed to him contracting terminal cancer.

Monsanto is to vigorously appeal the ruling.

Roundup contains the herbicide glyphosate which is widely used in British agriculture.

The NFU has said glyphosate is important for controlling weeds and also the mycotoxins which are produced.

Mycotoxins are toxic chemicals produced by certain fungi that can grow on a variety of different crops and foodstuffs. Different fungal species produce mycotoxins of widely varying toxicity to humans and animals. In cereals, mycotoxins can result from fungi that either develop in stored crops or from field-borne infections.

An NFU spokesman said: “A range of broad-leaved and grass weeds can carry Fusarium leading to infected weed and crop debris as well as carry over spores. By controlling these weeds, levels of Fusarium and hence mycotoxins can be reduced.”

The NFU is now urging the farming community to write to the Commissioner for Health and Food Safety and to UK MEPs on the EU agriculture and environment committees to underline the importance of glyphosate.

MEPs are due to vote later this month on whether the European Commission’s proposed re-authorisation of plyphosate should be removed pending further analysis of the environmental and human health impacts of the herbicide.

They want MEPs to oppose the resolution, citing the European Food Safety Authority conclusion that “glyphosate is unlikely to pose a carcinogenic hazard to humans.”

Monsanto vice president Scott Partridge said the company would appeal the verdict claiming hundreds of studies showed the herbicide does not cause cancer.

“We all have sympathy for what Mr Johnson is going through; cancer is a terrible disease,” Mr Partridge told BBC Radio 4’s Today programme.

“I’ll tell you that this verdict doesn’t change the four plus decades of safe use and science behind the product.

“There have been over 800 medical scientific peer review published studies that have established there is no link whatsoever between glyphosate and adverse health effects, much less cancer.”

South African barley concern

I read a really interesting article today about barley production in South Africa. It seems growers are up in arms. This article is by Shem Oirere.

South Africa has for many decades recorded a deficit in its barley production volumes in spite of government projections of an increase in area under production by 16.2percent to 106,150ha.

Narrowing the barley production deficit in South Africa would require not only an increase in the acreage under the crop but also improvement in the quality of the produce to ensure more sales to the country’s new beer brewing monopoly Belgian-based multinational beverage and brewing holdings company Anheuser-Busch InBev (AB InBev).

Apart from the unpredictable weather in key barley growing areas of Northern Cape, Southern Cape and North West Province, which has in recent times devastated cereal crops in South Africa, concerns have also been raised by the country’s grain producers on the likely impact on production of a review of the barley pricing structure by AB InBev after its recent completion of the acquisition of SABMiller.

The concerns became more pronounced in May 2018 when the barley farmers raised the alarm over possible adverse impact of AB InBev’s proposal to review the nine-year-old barley pricing structure that has been tied to the wheat futures at the Johannesburg Stock Exchange (JSE).

Before the merger with SABMiller in South Africa, AB InBev was supplying beer products such as Corona Extra, Stella Artois, Beck’s Blue and Budweiser brands largely imported and distributed via DGB (Pty) Ltd (DGB), a global distributor of alcoholic products.

SABMiller on the other hand was in the period preceding the merger active in South Africa market as the largest producer of beer products trading under brand names such as Carling  Black  Label, Castle  Large,  Hansa, Castle  Light  and Peroni.

A revised pricing structure for the 2008 barley crop according to Pretoria-based Grain SA, a non-profit organisation that champions interests of grain producers of South Africa, would result in farmers earning less than initially projected.

The grain farmers’ lobby has sought for the intervention of South Africa’s Competition Commission after AB InBev the new pricing structure would result in barley growers being paid 97 percent of the price for top grade wheat (B1) for the 2008 crop from 102 percent of second tier wheat (B2).

SABMiller had in 2009 linked the price of malting barley to the wheat futures price at the South African Futures Exchange (Safex), a futures exchange subsidiary of Johannesburg Stock Exchange Limited exposing the barley producers to a huge price risk.

Who would have thought barley could have such a key role in SA?

Leading UK manufacturer of grain silos launches additional brand

Bentall Rowlands Storage Systems, founded in the 1800’s, and now one of the world’s leading manufacturers of grain silos and storage systems, sees the launch of their new ‘BRSS’ secondary corporate identity in June 2018.

This addition to the Bentall Rowlands brand, will not be replacing the existing corporate identity, but simply enhancing their existing brand and will be used on all future completed silo projects around the world.

In addition to being CE Certified, their team of highly-skilled engineers manufacture all products in-house in a dedicated manufacturing facility in Scunthorpe, UK, supplying into worldwide agricultural and industrial markets.

A great loss to the industry – Mark Cornwell

Mark “Cornman” Cornwell died unexpectedly at his home on 11th September 2017 in Leawood Kansas at the age of 61. Mark is survived by his wife Martha and step daughter Maggie McGilley along with his three sisters Carole, Connie and Kristi and his two beloved dogs Abbie and Marley, who will miss having Mark to play with them. Mark was born on April 16, 1957 in Kirksville, Missouri to Clifton and Una Cornwell. He graduated from the University of Missouri in Columbia on a golf and thespian scholarship where he was a member of the Kappa Alpha Fraternity and as such was an avid fan of Mizzou football, as well as the Kansas City Chiefs football team and his beloved St. Louis Cardinal baseball team. After leaving university, Mark was a partner in the Mister Guy clothing franchise in Little Rock, Arkansas. He came to Kansas City in the late 1980s where he started a career with Sosland publishing company as the publisher of World Grain Magazine. Mark was a long-time associate of the grain and milling industry, and having spent many years with World Grain helping build a leading industry magazine he then went on to partner with Perendale Publishers in 2014 to work on the oldest publication in the milling sector, Milling and Grain magazine, along with his wife and business partner Martha. Mark was accomplished at building relationships and making friends and over the years has gained a network of friends on every continent on the planet. He was a generous and witty individual with a sense of humour that would make even the grumpy old men in a room laugh, and the character to always do the best job possible for those he served as well as being someone always willing to help people who might be struggling either personally or professionally. Mark was an icon of the grain and milling industry. A man of minimal fuss he loved his music and was passionate about fly fishing. Not wanting any fuss Mark had requested no funeral rather opting for a quiet private cremation which was carried out as per his wishes on Wednesday 13th September. However, a celebration of his life will be scheduled soon. All are welcome to attend and celebrate Mark’s life. In lieu of flowers a charitable foundation will be set up in Marks name to establish a new scholarship at his local university. The family would like to thank everyone that has been so supportive from all over the world with their kind words and support.

Henry Simon production has started!

Alapala and Satake partnership initiated the production of the milling legend Henry Simon. The pre-launch meeting was held between April 23 and 25, 2017 in Alapala’s headquarter in Çorum, Turkey. The new Henry Simon milling machines will be introduced at the 121st Annual IAOM Conference & Expo which will be held between April 10 and 14, 2017. This take off will be a prologue to the new era of global milling sector.

Japan’s first power driven rice milling machine inventor Satake and 60 yearlong global grain milling technology provider Alapala had signed a strategic partnership agreement in 2015. Both companies had combined their production, R&D, sales, marketing and aftersales forces in the scope of this agreement. As a second and a further step of the agreement, Satake and Alapala regenerate the oldest and the best known, legendary brand of milling technologies.

Henry Simon milling company was founded originally in England by the German engineer Henry Gustav Simon in 1878. More than 400 Henry Simon branded mills was established all over the world, with innovations such as the first double roller mill and the first PLC automation system.

One of these 400 Henry Simon branded mills was “Hatap Un” which was established in Çorum in 1961. Also Mehmet Alapala, the founder of Alapala, entered to the sector by producing wooden sifter for “Hatap Un” mills. Following years, joining with Robinson Milling Company, Henry Simon brand was sold to Satake in 1991.

By the year 2017, Alapala and Satake resubmit the Henry Simon brand to the market. Alapala’s capacity increasing investments, spare parts supply and aftersales services ally with Satake’s active sales network and gigantic R&D team to revive Henry Simon brand.

With the force of Henry Simon brand and Satake partnership, Alapala will move up its worldwide power by reaching new more 55 countries in addition to its existing experience of more than 600 turnkey projects in 100 countries.
