Description

Technical Field

[0001] The invention relates to a sterilization tank, in particular to a steam sterilization tank. Background Art

[0002] Pre-prepared meals, also known as pre-made dishes, are the product of food industrialization. During the preparation and processing process, pre-prepared meals use one or more edible agricultural products and their products as raw materials. They are made in large quantities through industrial pre-processing (such as stirring, marinating, tumbling, kneading, molding, frying, frying, baking, boiling, steaming, etc.). They are pre-packaged dishes that can only be eaten after heating or cooking. They do not include staple foods such as quick-frozen noodle and rice foods, convenience foods, boxed lunches, rice with gravy, steamed buns, pastries, roujiamo, bread, hamburgers, sandwiches, pizza, etc.

[0003] In the process of preparing and processing pre-prepared dishes, it is often necessary to heat a large number of pre-prepared dishes so that the pre-prepared dishes can be cooked and sterilized at the same time. In actual use, although the food processing devices in the prior art can achieve the basic effect of processing pre-prepared dishes, they can generally only perform cold processing on the pre-prepared dishes. After the processing by the food processing device is completed, the pre-prepared dishes are manually heated by water.

[0004] During the preparation and processing of pre-prepared dishes, some dishes often need to be immersed in hot water for pre-cooking. However, when pre-prepared dishes are produced in large quantities, a large number of dishes need to be pre-cooked, and the manual labor intensity is high, which will affect the overall production efficiency of the pre-prepared dishes.

[0005] Although this processing method can complete the cold processing and heating treatment of pre-prepared dishes, it still has the following defects:

[0006] 1. Manual pre-cooking of the food is labor-intensive and reduces production efficiency.

[0007] 2. The efficiency of water heating is slow, which not only reduces the production efficiency, but also may cause the water temperature to drop after the pre-prepared dishes are put into the water, resulting in insufficient heating temperature and causing food safety problems.

[0008] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the application, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to ordinary technicians in this field.
