As summer comes, many regions and provinces have launched special food safety rectification actions to maintain consumer food safety. Food safety is an important factor in ensuring social stability. According to statistics, nearly one in ten (550 million) people worldwide suffer from foodborne diseases every year. Therefore, the prevention of foodborne diseases in the food industry cannot be ignored. As an integral part of the food industry, food machinery manufacturing also plays an important role in the prevention and control of food safety issues.

In recent years, the scale of domestic food manufacturing has continued to expand. In 2019, the operating income of food industry enterprises above designated size in the country was 8,118.68 billion yuan, an increase of 4.2% year-on-year. At the same time, the food industry is also entering industrial production from manual production. The application rate of food machinery continues to increase, driving the expansion of the food machinery manufacturing industry. According to statistical data, at present, my country's food processing and packaging machinery manufacturing enterprises have reached nearly 7,000.

Moreover, the types of domestic food machinery are constantly being updated. Food machinery is mainly divided into two categories: food processing machinery and food packaging machines. The existing food processing machinery includes cleaning equipment, crushing equipment, drying equipment, freezing equipment, molding equipment, concentration equipment, etc., and packaging machinery includes packaging equipment, packaging printing equipment, etc. With the efforts of technicians, my country's food machinery technology continues to improve, and has made major breakthroughs in the fields of automation, intelligence, and greening.

But in addition to the performance of the equipment, the quality and safety of the equipment cannot be ignored. As we all know, safety is a key factor in food production. Therefore, in the development and design of food machinery, it is necessary to meet the safety requirements of food production as much as possible to avoid safety problems in the food produced.

So, what are the health and safety requirements for food machinery during production? The first is that the raw materials of equipment cannot affect the quality of food raw materials. Therefore, food-grade stainless steel with a smooth surface, easy cleaning, and strong corrosion resistance should be used on the surface where the equipment directly contacts with food. The types of stainless steel commonly used in the market for food equipment processing are 304# stainless steel and 316# stainless steel. The two correspond to different national standards. Enterprises need to choose according to the type of equipment production.

Secondly, when designing the structure of the equipment, easy cleaning should be taken as an important indicator. For detachable machinery, the equipment should be easy to disassemble and clean, and non-removable should be designed to be able to be cleaned online; the component structure of the equipment must ensure that there are no sags and dead corners of liquid retention to avoid the phenomenon of dirt collection; the support of the equipment is also To avoid the design that is easy to allow dirt to remain, provide a space that is easy to clean and inspect.

In addition, the connection between equipment parts should also be paid attention to. The continuous joint between metal and metal should be continuous welding structure, and the connection is smooth. Metal and non-metal or non-metal and non-metal should be continuously bonded; the use of fasteners such as screws and screws should be minimized on the equipment. The above requirements also require good tightening work to avoid exposure; some bearings should also be avoided, or try to use non-lubricating, product lubrication type bearings.

In the past two years, domestic manufacturers have become more and more strict with food safety requirements, and the sanitary safety requirements for food machinery have increased a lot. When designing equipment, domestic food machinery manufacturing companies must strictly follow the standards of GB 16798-1997 "Food Machinery Safety and Sanitation", JB 7233-1994 "Packaging Machinery Safety Requirements" and other standards, so that the product materials, structural design, parts connection, etc. Hygienic requirements for machinery manufacturing.
