At STOCK, our mission is to provide our customers application

specific, innovative sterilization solutions while maintaining the highest

level of operational standards in safety, service, and reliability.


STOCK America was started in 1975 by Hermann Rudolf STOCK, owner of the German-based Hermann

STOCK Maschinenfabrik (HSM) and the inventor of the original STOCK rotary batch sterilizers.


Our initial focus in the 70’s and early 80’s was introducing the U.S. food industry to the technological advantages of end over end (E-O-E) rotation and full water immersion processing inherent in the

‘Rotomat’ batch retort. These types of retorts had found favor in European and Asian markets decades earlier due to the flexibility of the equipment, radical reductions in process times and the increased

quality of end products. This was a novel approach compared to the simple steam retorts that

dominated the U.S. market.


STOCK America continued to grow and expand our U.S. based competencies through the 1990’s and

into the 21st century. We invested in our own control engineering capacity and developed our “award winning” ICON control system, which received FDA acceptance in 1994.


In 2002, we broadened our product line to include energy efficient static and rotary steam spray retort systems through a distribution agreement with SURDRY S.L. of Spain.


In 2006, STOCK America broke ground on a new assembly and testing facility for the U.S. located in Raleigh, N.C.


In 2010, DFT Technology GmbH in Neumünster, Germany licensed the exclusive North America manufacture of their trademark STOCK Immersion retorts to STOCK America Inc.  Domestic U.S. retort manufacturing began at our facility in Raleigh, NC and the product was evolved to fit the requirements of the North American market.


In 2010, STOCK America began representation of ACB HYDROLOCK Continuous Sterilizers to complement our line of overpressure batch thermal processing systems.


In 2011, STOCK America became the exclusive distributor of LAN Handling Systems, Int’l for the territories of USA, Canada, and Mexico.


In 2011, STOCK America became the exclusive provider of the control systems and process validation services for new microwave sterilization systems working with Food Chain Safety, Microwave Materials Technologies and Washington State University.


In 2012, STOCK America entered into an exclusive thermal processing partnership with TechniCAL.  As the industry’s leading independent “Process Authority”, TechniCAL’s Web enabled “Process Cloud” allows customers to store all pertinent process information on secure off-site storage as well as upload deviations for Thermal Process Authorities to review.


In 2013, STOCK America became the exclusive distributor of ACB HYDROLOCK Continuous and Pilot Sterilizers for the USA along with territory rights in Canada.
