Stoning machine for wheat

Abstract

The invention discloses a stoning machine for wheat. The stoning machine for wheat comprises a spin-dry device. The spin-dry device comprises a conical rotating drum and a feeding cylinder, wherein the major diameter end of the rotating drum faces upwards, the feeding cylinder is rotationally connected to the lower end of the rotating drum, a first rotating shaft is arranged in the feeding cylinder and provided with a first spiral groove, and the upper end of the first spiral groove extends into the rotating drum. The stoning machine for wheat further comprises a water tank. A connecting cylinder is arranged between the side wall of the water tank and the side wall of the feeding cylinder, the connecting cylinder is communicated with the water tank and the feeding cylinder, a feeding hopper is arranged at the top end of the water tank, a second rotating shaft and a third rotating shaft are arranged in the water tank, the second rotating shaft is located above the third rotating shaft, the second rotating shaft is provided with a second spiral groove, one end of the second spiral groove penetrates through the connecting cylinder and makes contact with the peripheral end of the first spiral groove, the third rotating shaft is provided with a third spiral groove, and the third spiral groove penetrates through the side wall of the water tank. The stoning machine overcomes the technical defect that stones in wheat cannot be removed through the existing wheat impurity removing technology. The stoning machine for wheat can remove stones.

Description

technical field [0001] The invention belongs to the field of food impurity removal, and in particular relates to a wheat stone removal machine. Background technique [0002] Wheat is one of the three major grains. Wheat is rich in nutrients such as starch, protein, fat, minerals, vitamin A and vitamin C, and is also one of people's staple foods. [0003] People usually grind wheat into powder, that is, flour, and eat it. Before processing wheat, it usually removes impurities. The current method of removing impurities for wheat is usually sieving and removing impurities. Screening is carried out in the sub-machine, and debris such as straw with low density and large size floats on the upper layer during the vibration process, while wheat with high density and small size sinks to the lower layer and falls through the sieve holes on the sieve. To the outside of the screening machine, so as to realize the separation of wheat and sundries. However, wheat is usually mixed with s...
