Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food production, in particular to a processing system for frozen food. BACKGROUND

[0002] Since instant foods such as instant noodles, vermicelli and the like are processed foods obtained by drying, the types of processable vegetables are limited, which makes the nutritional value of the products monotonous and unable to provide a relatively fresh and better-tasting eating experience. In addition, during eating, water needs to be boiled in a pot for cooking before the food can be eaten. This preparation method usually takes 10-15 minutes and involves multiple steps, which is very laborious and time-consuming, and is inconvenient. Moreover, the amount of water used has a great impact on the richness of the taste of the food. Therefore, there are frozen foods that integrate soup, noodles and vegetables, such as Chinese patents CN115720985A and CN115399437A, which are packaged integrally, are environmentally friendly, and can be eaten directly after heating to boiling during eating. However, based on the preparation equipment and process corresponding to the existing technology, the soup cake and noodle cake will be frozen together during the integrated freezing of the soup, noodles and vegetables, which makes it impossible to separate the noodle cake and the soup cake for individual heating. In addition, the soup cake needs to be frozen first, and then the noodle cake and toppings are placed on the soup cake for secondary freezing. After the secondary freezing is completed, demolding and heat shrink packaging are performed, and then tertiary freezing is performed after the heat shrink packaging is completed. Multiple freezing processes will result in long processing time and low work efficiency. Moreover, the demolding process is not easy to realize automatic process, and the outer surface of the demolded product is in a dripping state, which will pollute the device during the conveying process and breed bacteria. Since it is not easy to clean, bacteria will affect the quality and safety of the food in the later stage. SUMMARY

[0003] Therefore, the present application provides a processing system for frozen food to solve the technical problems of low work efficiency and uncontrollable food quality.
