Description

Technical Field

[0001] The invention belongs to the field of intelligent food manufacturing and packaging, and in particular relates to a pre-cooling device for a partitioned filling and punching type food packaging machine. Background Art

[0002] At present, there are various ways to process food, among which baking is one of the ways of food processing. After the processing of baked food, it is generally necessary to package it through a packaging machine. Since there is no cooling mechanism on the existing packaging machine, the temperature of the baked food itself is relatively high after packaging, which may easily cause the packaging bag to react under high temperature and produce harmful substances that may contaminate the food. Therefore, the baked food needs to be cooled. The existing method is to transport the baked food from top to bottom through a pipe, and to achieve the cooling effect by transporting cooling air into the pipe. However, the baked food is generally brittle, and it is easy for the baked food to be bumped when transported from top to bottom through the pipe, causing the food to be damaged. However, the effect of directly cooling the stacked baked food with air flow is poor. Therefore, it is necessary to design a cooling and transportation method to avoid food damage and improve the cooling efficiency. Summary of the invention
