Technical Field
[0001] The utility model relates to the technical field of food processing, in particular to an automatic start-stop mechanism with a pure mechanical structure. Background Art
[0002] Rice crackers are rice-based snack foods made from rice using different processes and recipes. Most rice crackers are crispy, have a strong rice aroma, and are low in fat and sugar, making them very popular among modern consumers, such as snow cakes, rice crackers, rice crackers, and rice crackers with fillings. Rice crackers are characterized by being easy to bite, suitable for all ages, and not bloating the stomach. They are nutritious, inexpensive, safe, and free of the risk of oil deterioration.
[0003] The rice cracker production line uses negative pressure Roots fans to suck embryos. The Beijing plant is equipped with 3 Roots fans. According to the changes in the production line, personnel are required to participate in the start and stop of the machine and the switching of the valves. If the switching is delayed or wrong, it will directly cause an alarm and shutdown. The fan room is set outdoors, and personnel need to go through the disinfection room to enter and exit. The long entry and exit time affects the production of the workshop, so it is necessary to improve the original pipeline manual butterfly valve. Utility Model Content
