Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of green food production, and in particular to a crushing device for agricultural product processing. BACKGROUND

[0002] In the field of deep processing of green agricultural products, crushing and even fine grinding of raw materials into powder is a key process to improve product added value and expand application scenarios. Especially for green agricultural products such as whole grains, herbal plants and medicinal fungi, turning them into powder not only greatly retains their natural dietary fiber, vitamins and bioactive ingredients, achieving full utilization of nutrition, but also facilitates the production of instant beverages, nutritional supplements or health food bases, meeting the needs of modern consumers for natural, convenient and functional foods. Therefore, developing efficient crushing and grinding equipment is crucial to maximizing the value of green agricultural products.

[0003] However, the existing crushing and grinding devices generate a large amount of heat due to the intense friction and extrusion between the grinding components and the material during operation, especially when processing powder. This results in a sharp rise in internal temperature of the equipment. The existing equipment generally has the defect of poor cooling effect. This accumulated heat cannot be dissipated in time, which has a significant negative impact on heat-sensitive powdered agricultural products. Not only does it cause vitamin destruction, aroma volatilization, and antioxidant inactivation, resulting in loss of nutrition and flavor, but it can also cause protein denaturation or starch gelatinization, leading to powder caking and deterioration, and even accelerate the oxidation and rancidity of oil-rich products, seriously damaging the quality and safety of the final product. Currently, although some equipment attempts to set up water cooling and other cooling measures for the grinding structure, it usually needs to configure an independent water pump and other necessary driving sources, increasing the operating energy consumption, which is contrary to the concept of energy saving and consumption reduction in green processing.
