Description

Technical Field

[0002] Bean crushing is a basic operation in food processing, which aims to convert various beans such as soybeans, mung beans, black beans, etc. into fine particles or powders through mechanical force. This process first requires the selection of raw materials to ensure that the beans are fresh, dry and free of impurities, followed by necessary pretreatment. For example, for beans with higher hardness, they may need to be soaked in advance to soften their texture for subsequent crushing operations. Next, the pretreated beans are poured into a special crusher or grinder, which is usually equipped with sharp blades or grinding discs to crush the beans through shear force and friction generated by high-speed rotation. During operation, the speed and time of the crusher need to be adjusted according to the required fineness of the powder to achieve the ideal particle size distribution. At the same time, to ensure food safety and hygiene, the crushing container and contact parts should be kept clean and thoroughly cleaned and disinfected after each use. Finally, the crushed bean powder is not only easy to digest and absorb, but also broadens its application range. It can be used to make a variety of foods such as soy milk, tofu, and cakes, enriching people's dietary choices.

Therefore, it is necessary to provide a top cover structure that can be easily opened to make the rotating shaft and the crushing shaft easier to take out and clean. Summary of the invention
