Our History
Origin

It was in the development of the Wildfire Chemical Business that Mr. Handleman designed and patented the initial Ejector Mixer Slurry Unit and the precursor to the Air-Pallet® Container. The development of the Ejector Mixer and the shipping container with the air membrane in the base made it possible for Monsanto to offer a fire retardant chemical in the form of a dry powder and rapidly convert the powder into a solution to be pumped aboard airplanes to bomb forest fires and minimize the impact on the environment. This technology continues to be the primary process support for fighting forest fires in a number of world areas.
1975-1995 – The Early Years – SBS 1.0

The company produced a full line of products including Air-Pallet® Containers in round, rectangular and mini configurations; Industrial Air-Cone® Hoppers; and fill and unload units and systems for APC handling. These products were used in a variety of chemical and industrial industries like PVC, printing ink, chemicals and filter aids.
1975 – 1979: 
1979-1994: The Company moved into a new 20,000 square-foot manufacturing, operation, office, and pilot plant in Overland, Missouri. Provided initial facility for Air-Pallet® Container assembly, manufacturing of filling and unload systems for the Air-Pallet® container, and expanded pilot plant for testing and demo of a large range of powders. The Company moved to an expanded 65,000 square feet manufacturing, office, and pilot plant facility at current location in Fenton, Missouri. Provided additional space required for manufacturing of process equipment, pilot plant facility and expanded office requirements.
1996-2016 – Semi-Bulk 2.0
1995: Decision was made to reduce emphasis on air-pallet container business and increase emphasis on process business and sanitary markets versus industrial markets and products. Adopted manufacturing practices related to 3A Sanitary Fabrication. Began developing processes related to sanitary handling of powder and processes related to powder/liquid mixing.
Mr. Handleman retired from Semi-Bulk Systems in 1996 shortly after the formation of the Semi-Bulk Systems Sanitary Division (food, dairy, beverage, cosmetic and pharmaceutical) in 1995. Mr. Ronald Bentley was named Director of the new division. The VACUCAM® (VACUUM Convey and Mix) Slurry Processes were expanded to offer both the food and industrial markets this state-of-the-art technology for mixing powders and liquids.
Although systems were previously sold for such processes, the company began to focus on these hygienic processes for dry powder handling and powder/liquid mixing. To support and promote the VACUCAM® Slurry Process Technology, Semi-Bulk’s product lines were expanded, adding many new products to meet the requirements for hygienic processes. These new product lines were developed to offer a TOTAL SOLUTION, including dry side modular processes with Air Cone ® Hopper (ACH) and powder/liquid mixing modular processes based on Vacucam® Ejector Mixer (EJM) and full solution standardized modular skidded powder mixing processes.
The products developed to focus on conditioned powder feed included bulk bag unload stations, bulk bag unloaders with surge bins, hygienic design Air-Cone® Hoppers and many new modular processes.
With the achievement of ISO 9001 and 3-A Certification as well as sanitary fab transition, Semi-Bulk Systems expanded into new food, chemical and industrial markets including dairy, beverage, sugar, power plants, paint and others serving both smaller operations as well as Fortune 50 manufacturers.
At the same time, Semi-Bulk Systems began expansion of distribution outside the United States into Europe, Mexico, China, Asia, Brazil, Japan and India.
1997: Introduction of the first bulk handling Sugar Liquefication process designed to vacuum convey sugar from bulk truck unload with water on a Continuous Steady-State (on-demand) basis. Used for handling large volume ingredients. Original installations with U.S. ice cream facility.
1998: Company achieved ISO 9001-1994 Certification. SBS currently holds ISO 9001-2015 Certification. Provided credibility and capability to increase emphasis in manufacturing for sanitary processes and projects through major engineering houses.
2000: Introduction of the EJM 2000 Inline Mixing Skid unit designed to vacuum convey conditioned powder from various powder sources, mix powder with liquid media on a Single Pass or Batch Recycle basis. Used for handling most medium volume ingredients, including those with higher solids. Original installations within various U.S. based paint and cheese facilities.
2004: Introduction of the Mixer-on-Stand (MOS) unit specifically designed for optimum dissolution of thickeners, gums, dairy protein powders, and sensitive ingredients, typically lower solids (<20-30%). Original installation at a paint plant in Sweden.
2012: Established representative presence in China as well as expanded presence in multiple paint plants in China and additional systems with international paint plants in multiple Asian countries.
