Description

Technical Field

[0001] The utility model relates to the technical field of sterilization, in particular to a canned food sterilization device. Background Art

[0002] After canning is completed, for example, canned food, its raw materials need to be sterilized after pre-treatment, canning and sealing. The purpose is to kill the pathogenic bacteria, toxin-producing bacteria and spoilage bacteria contaminated in the food, and destroy the enzymes in the food. The sterilization method currently used is generally high-temperature sterilization. Since the sterilized cans are in sealed conditions, secondary contamination by external microorganisms can be prevented, allowing the cans to be stored for a long time without deterioration.

[0003] When sterilizing canned food, the higher the sterilization temperature and the longer the sterilization time, the more thorough the sterilization will be. However, the nutritional components of the canned food as well as the color, aroma, and texture of the food will also be destroyed. Therefore, when sterilizing canned food, while considering the sterilization process, the color, aroma, and nutritional components of the food should be preserved as much as possible. In addition, during the sterilization process, the sterilization environment needs to be sealed. If exposed to the air, the microorganisms in the air will still adhere to the canned food. In order to sterilize thoroughly, this open sterilization equipment prolongs the high-temperature sterilization time during sterilization, which will cause color, aroma, and texture problems of the canned food. Therefore, setting a sealed sterilization environment is also an important factor in reducing the sterilization time and thus reducing the impact of high temperature on the color, aroma, and texture of canned food.
