Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food production, and in particular to a raw material mixing device for edible fungus strain cultivation. BACKGROUND

[0002] In the fields of edible fungus cultivation and agricultural and forestry waste resource utilization, the pretreatment of raw materials such as sawdust, cotton seed hulls, and straw is a key link to ensure the efficiency of subsequent fermentation, cultivation, or transformation. The pretreatment needs to achieve both particle looseness and uniform moisture through dispersion and wetting. These raw materials often have characteristics such as high fiber content, large particle size difference, and significant water absorption differentiation. For example, straw has a moisture content of 35%-50% and is prone to clumping, while sawdust has a significant difference in water penetration rate due to its wood structure.

[0003] For example, the Chinese patent with publication number CN118718842B discloses a raw material premixing device for edible fungus strain cultivation. The device feeds multiple materials into a stirring cylinder through the feed inlet. The main shaft and stirring shaft are controlled by a rotation control device to rotate around their respective axes. The rotation of the stirring shaft stirs the materials in the stirring cylinder, improving the mixing of the multiple materials. The rotation of the main shaft drives the stirring cylinder connected to it to rotate around the main shaft in an inclined state. The inclined axis of the stirring cylinder allows the materials to be better turned inside the stirring cylinder, promoting contact between the materials and the stirring shaft, thereby improving the mixing of the multiple materials.

[0004] The above and existing related technologies have the following defects: The traditional spraying or soaking method easily causes dry materials to wrap wet materials. High water absorption raw materials swell on the surface and wrap the dry particles inside. Low water absorption raw materials cannot achieve deep infiltration because the surface water film easily falls off. In addition, due to the large difference in density and particle size of different raw materials, layering easily occurs during stirring. SUMMARY

To solve this problem, the present application provides a raw material mixing device for edible fungus strain cultivation.
