Food processing equipment refers to machinery, pipelines, conveyor belts, etc. that come into direct contact with food during the production and processing process.

(1) Basic structure of food processing equipment

① Power part: It is the part that completes energy conversion, such as converting electrical energy into mechanical energy and chemical energy into thermal energy;

② Transmission part: complete the conversion of power mode, such as speed change, direction change, rotation-straight line, rotation-curve, straight line-curve, constant speed-speed change;

③Execution part: directly complete the operation functions, such as cutting, crushing, filtering, mixing, and emulsification;

④Support part: organically connect the various parts of the equipment together and determine their positional relationship;

⑤Connection part: connected with related equipment before and after, such as feeding and discharging, orientation and sorting devices;

⑥Control part: used to control the working status and operation process of the equipment, such as control cabinets, switches, and safety protection devices.

(2) Characteristics of food processing equipment

With the progress of society and the development of economy, the traditional industry of food processing has undergone tremendous changes. Food processing is gradually transforming from manual production to large-scale mechanized production, with the following characteristics:

① The categories are complicated, and the raw materials, products, and material characteristics are complicated and diverse;

② Diverse structural forms, many non-standard products, and many non-standard equipment;

③Good versatility, especially for the main raw materials of food manufacturing, agricultural products, whose output is highly seasonal, so in order to improve the utilization rate of equipment, one machine should be used for multiple purposes;

④High hygiene requirements, especially for the parts in direct contact with materials, which should be made of non-toxic and corrosion-resistant materials, have smooth surfaces that are easy to clean and disinfect, and have sealing measures to avoid lubrication leakage, etc.;

⑤High degree of automation, including process control, etc.

(3) The role of food processing equipment in the food industry is mainly reflected in the following aspects:

① Standardize production procedures and ensure product quality. By setting reasonable operating procedures and using machines to automatically complete operations, the direct involvement of people and the randomness of operations in the traditional production process are reduced, and the uniformity of product quality and sanitary quality are better. This is the main means to ensure product standardization, an important feature of the modern food industry.

② Reduce production costs. Due to the improvement of labor productivity and product quality, and the use of machinery to make more full and reasonable use of raw materials, material consumption is reduced, so that production costs can be effectively reduced.

③ Reduced labor intensity and improved labor productivity. One operator can manage one, several or even a set of high-production capacity equipment at the same time.

④Improved working conditions.

⑤It can complete tasks that cannot be completed manually.
