Clean the bean raw materials to remove impurities and surface dirt. Steam and boil the washed beans to achieve an appropriate softness and tenderness. Wash the cooked beans to separate the red bean paste. Dehydrate the red bean paste to reduce its moisture content. Stir-fry the red bean paste in a vacuum environment to enhance its taste and flavor. Then, transport the stir-fried red bean paste to the subsequent processes. Air-dry the bean paste, further adjust the moisture content, cool the air-dried bean paste to an appropriate temperature, carry out sterilization treatment on the bean paste to ensure product hygiene and safety, flatten the bean paste for subsequent packaging, vacuum package the bean paste, and complete the finished product production.
