In fact, the central kitchen is the carrier of the industrialized application of prefabricated staple food and dishes in the catering industry. Prefabricated staple foods and dishes refer to ready-to-eat foods or semi-finished products and finished products that can be eaten by simple heating or simple conditioning after pretreatment such as cleaning, cutting, molding or heat treatment, seasoning, packaging, cold storage (or quick freezing) or sterilization, such as grains, potatoes, fruits and vegetables, livestock and poultry products, aquatic products, etc. Industrialization of prefabricated staple food and dishes refers to the process of applying modern science and technology and advanced equipment to replace traditional manual production with quantitative, standardized, mechanized and automated processing to realize industrialized production. Through industrialization, the manual operation of chemical system is transformed into mechanized production, manual control into automatic control, fuzziness into quantitative and qualitative, and randomness into standardization, thus realizing the scale, standardization and automatic production of catering cooking. This is not only a revolution in kitchen engineering, but also of great significance to improve the standardized production level, product quality and people's diet health level of catering products and accelerate the development of China's catering food industrialization system.
