AI Technical Summary

Problems solved by technology

[0003] The design of the interlayer structure and heat preservation structure of the steam jacketed pot in the prior art is relatively simple, the heating efficiency is not high, and its heat preservation ability is also poor. Steam leakage is generated, which poses a safety hazard; at the same time, when this kind of steam jacketed pot is processed in batches of high-temperature stewed food in food processing enterprises, it will also cause hot and humid workshops, diffuse steam, low visibility and serious condensation water phenomenon due to steam leakage. , even if high-power forced air supply and exhaust equipment is used for ventilation, an ideal and comfortable environment cannot be formed. The physical comfort of employees is extremely low, and the risk of food safety is also relatively high.

[0004] In addition, due to the difficulty of controlling the welding process, it is difficult to completely eliminate the welding residual stress generated during the welding of the jacket and shell of the jacketed pot, and the area near the weld seam will cause large Cyclic thermal stress can easily cause stress corrosion cracking after a period of use

In addition, austenitic stainless steel with non-magnetic, good corrosion resistance and processability is often used in steam jacketed pots, but in the process of food thermal processing, some seasonings, especially halogen materials, contain more chloride ions , but ordinary austenitic stainless steel is very sensitive to the medium containing chloride ions, and will cause stress corrosion cracking of the metal under the influence of chloride ions during the long-term high-temperature contact with food materials

Although the film passivation treatment will be carried out on the inner side of the sandwich pot, due to the small radius of the chloride ion and the strong penetrating ability, it is very easy to penetrate the very small pores in the passivation film, and adsorb on the passivation film, and interact with the passivation film. The cations in the film combine to form soluble chloride, which destroys the passivation film, and the austenitic stainless steel in the passivation film damage area is directly exposed to the corrosive environment to cause electrochemical corrosion, which ultimately affects food quality and safety
