REDUCE HACCP RISK FACTORS G
eared motors are used throughout the production line at many food processing facilities. Compact and energy efficient,
they are the ideal design to drive stirrers, agitators and conveyors. However, although standard designs offer the performance parameters required by the average food manufacturer, the strict hygiene regulations mean that in many applications, specialist motors are preferable. Te Hazard Analysis and Critical
Control Point (HACCP) system is an internationally recognised method for reducing risk factors in the production or processing of food. As a process for on-going improvement, it requires

manufacturers to continuously evaluate each process in its production line to identify possible hazards and minimise risk at critical points. Te primary purpose of the system is to protect people from foodborne illness, though it is also recognised as a ‘best practice’ approach to improve quality and consistency in the final product. Understanding the process of analysing risk in the production line and making improvements helps to explain the evolution in geared motor technology that is favoured by the industry. Looking to the past, geared motors were always recognised as a favourable drive system as they are efficient and reliable. However, as regulations surrounding hygiene
became tighter, it was soon necessary to source specialist solutions for the food & beverage industry. Aseptic drives were developed for applications where washdowns are required to maintain a clean environment. Drives are typically painted using acid- and alkali-resistant coatings, which can withstand chemicals with a pH range of 2-12. As a result, they can withstand the cleansing solutions and disinfectants that are commonly used within the food industry without affecting their performance. Aseptic drive solutions therefore deliver all the performance benefits of a standard geared motor, while eliminating some of the hygiene risks. However, with a
