Background Technique

[0002] The high-pressure cooking device for special dietary foods is a high-pressure cooking equipment designed specifically for making special dietary foods. It combines the characteristics of a pressure cooker and a cooking pot, and can efficiently and quickly complete the boiling process of special dietary foods while retaining the nutritional components of the ingredients. The working principle of the high-pressure cooking device for special dietary foods in the prior art is similar to that of an ordinary pressure cooker. The inner pot of the double-layer pot body is heated and raised in temperature by high-pressure steam, and the heat is transferred to the pot during the heating-up process. The materials in the pot will generate steam during the continuous heating process. Since the pot cover is designed with a high-pressure sealing mechanism, the steam continuously increases in the pot, thus forming pressure. When a certain pressure value is reached, the safety valve on the pot cover will automatically exhaust and relieve pressure to ensure the safety and controllability of the boiling process of special dietary foods.

[0003] The high-pressure cooking device for special dietary foods in the prior art is similar to the technical solution described in a high-pressure cooking pot for processing preserved fruits disclosed in Chinese Patent No. 2017214610628.

The technical problems existing in the high-pressure cooking device for special dietary foods with such a structure are easy to paste the pot, difficult to clean, and high labor intensity of workers.
