Description

Technical Field

[0002] Canned food is convenient, hygienic and easy to store, which meets people's daily needs and is increasingly popular. With the development of industrialized production and the improvement of people's living standards, consumers have higher and higher requirements for food, and pay more attention to food safety, nutrition and quality. The raw materials of canned food are mostly agricultural and sideline products. During the production and processing, some microorganisms may be contaminated. Some microorganisms may cause the ingredients of canned food to deteriorate and decompose. People are prone to accidental poisoning after eating spoiled canned food, which is not good for human health.

[0003] As canned food is increasingly being mass-produced, in order to ensure the safety of food, canned food needs to be disinfected and sterilized before it is packaged and stored. The quality of sterilization directly affects the quality of food. The commonly used sterilization method is hot water sterilization, which involves placing the cans in a sterilization kettle filled with hot water for heating and sterilization. However, this traditional hot water sterilization method cannot completely kill the bacteria inside the cans. At the same time, this method requires staff to place and take out the cans, which is a waste of time and cannot sterilize efficiently. At the same time, after some cans are heated for a long time, the internal components of the cans will be destroyed, and the taste and nutrition of the cans will be lost. Summary of the invention

The water pump 112 transports the water flowing into the recovery liquid chamber 116 to the working liquid chamber 115 through the water outlet pipe 113.

[0019] Before the hot water disinfection assembly 1 works, the strip rod of the baffle plate 111 coincides with the water injection hole 108. When the hot water disinfection assembly 1 works, the heating power supply I105 is started, and the heating power supply I105 makes the heating tube I106 work to heat the water inside the working liquid chamber 115.

The sterilized steam enters the condensation chamber 212 through the steam inlet groove 207 and adheres to the arc top 205. Since the arc top 205 is an arc-shaped structure, after the water vapor is liquefied into water, it will slide down the arc surface of the arc top 205 and flow into the steam generating chamber 211 through the condensing pipe 208.
