Description

Technical Field

[0001] The invention relates to the technical field of bamboo shoot mills, and in particular to a bamboo shoot mill and a milling method. Background Art

[0002] Milling machine is a kind of equipment widely used in the field of industrial flour making, with the characteristics of high efficiency, low consumption and environmental protection. Bamboo shoot powder is a powdered product made from bamboo shoots. Bamboo shoots are the tender shoots of bamboo and are rich in nutrients. Bamboo shoot powder can be used as a raw material or additive to develop various types of bamboo shoot-derived foods, such as bamboo shoot pasta, bamboo shoot biscuits, bamboo shoot bread, beverages, seasonings, etc. The production and use of bamboo shoot powder helps to improve the utilization rate of bamboo shoots, reduce waste and promote sustainable development.

[0003] Since bamboo shoots are edible processing materials, a large amount of deposited dust and soil will remain on the surface during processing. The moist soil on the surface will dry and harden after losing moisture. The bamboo shoot shell is a protective layer that wraps the tender bamboo shoots, which is composed of tightly arranged fibers. Compared with the bamboo shoots, the texture is harder. The shell mainly provides physical protection, while the internal structure is responsible for supporting the growth and nutrient storage of the bamboo shoots. The existing milling machine cannot target the structural characteristics of bamboo shoots, resulting in the bamboo shoot shell and the internal bamboo shoots being mixed together after grinding. In addition, the dust and soil remaining on the surface are not only mixed with the edible bamboo shoot powder, but also cause the bamboo shoot powder to have more impurities and lower quality. Therefore, a bamboo shoot milling machine and a milling method are proposed. Summary of the invention

The dust particles in the air flow are separated from the air flow due to the action of centrifugal force, and the heavier dust particles are thrown to the inner wall of the cone portion 302, and under the action of gravity, fall along the inner wall of the cone portion 302 and flow into the dust collecting chamber 304. The rotating air flow and finer particles shrink inside the cylindrical portion 301 and flow toward the center, forming a secondary vortex upward and flowing out through the outlet pipe 303.
