Problems solved by technology

Put the raw materials in the big pot and use fuel or electric heating to cook porridge and soup, all of which are to heat the bottom of the big pot. To boil the rice grains or other raw materials in the big pot requires continuous heating for a long time, which consumes a lot of energy and is low in efficiency. , the cost is high, and the current household pressure cooker and rice cooker cannot be used in the kitchens of factories, schools, troops and other institutions with a large number of people, which is inconvenient

Secondly, in the process of cooking porridge and soup, since the big pot is open, the fragrance, beneficial elements and steam in the raw materials of porridge and soup are released in the air, resulting in poor taste and mouthfeel of porridge and soup

[0003] When using a steam pot to cook porridge and soup, generally, the steam pipe is inserted into the steam pot, that is, the steam is used to impact the raw materials in the pot.
