Description

Technical Field

[0001] The utility model relates to the technical field of fermentation storage tanks, in particular to a children's rice flour fermentation storage tank with a pressure relief structure. Background Art

[0002] Rice noodles are a special snack in southern China. They are made from rice and are made into strips and threads through processes such as soaking, steaming, and pressing. Because of their soft and tough texture and rich nutrition, they are also used as children's food. There are many brands of children's rice noodles on sale.

[0003] Soaking and fermentation are necessary steps in rice noodle processing. Wash the rice and place it in a fermentation tank. Add clean water and close the lid. Ferment it in a warm environment for two to three days. Then you can take it out, clean it, and then make it into a pulp. Currently, the common children's rice noodle fermentation tanks on the market are mostly similar in structure. They are mainly made of stainless steel fermentation tanks with a sealing cover on the top. The tank body and the sealing cover are connected by a flange. The rice is placed in it for fermentation. There are some functional deficiencies in actual use and there is room for improvement. For example, rice is prone to produce gas during the fermentation process, forming high pressure in the tank. When the lid is opened later, it is easy to expand and overflow, affecting the production environment. It usually requires manual timed exhaust and pressure relief, which is more troublesome and does not have the function of automatic pressure relief.

[0004] Now, a novel children's rice flour fermentation storage tank with a pressure relief structure is proposed to solve the above problems. Utility Model Content
