Steam peeling machine is a new type of fruit and vegetable peeling equipment. The traditional peeling methods on the market now include chemical peeling and grinding wheel and roller peeling. The operating cost of chemical peeling is high, and there may be drug residues, which affect the quality of fruits and vegetables and also pollute the environment. The use of grinding wheel and roller for peeling causes significant wear and tear on the meat, resulting in waste. The pits on the surface of fruits and vegetables cannot be cleaned, leading to low peeling efficiency. A steam peeler is a device that operates at high temperatures and pressures (such as 200 ° C, 1 Saturated water vapor (2MPa) enters the closed cooking tank, causing it to be in a high temperature and high pressure state, and instantly (for a few seconds) insulate and steam the skin of potato fruits. After that, the saturated water vapor is quickly discharged from the tank through the steam port, restoring the tank to normal temperature and pressure. Thus completing the process of "high temperature and high pressure instant steaming and peeling at room temperature and pressure" for steaming and peeling. This process achieves rapid expansion and contraction of the skin of potato fruits through sudden heating and cooling, breaking the adhesion between the skin and meat, and forcing the separation of the skin and meat; On the other hand, high-pressure saturated water vapor infiltrates into the epidermis, and at the moment when it quickly empties and returns to normal pressure, the saturated water vapor suddenly expands, "supporting" the epidermis and meat, achieving the effect of puffing and peeling. In addition, the steam inlet and outlet are smooth, and the entire heating and pressurization process is instantly completed, only causing the skin to detach under the action of high temperature and high pressure, but the meat quality still maintains its original temperature and original flavor. Also, due to th
