Problems solved by technology

However, the current shelling machines at home and abroad adopt the ripening and shelling technology, which is cooked by boiling or microwave heating, and then shelled. Due to the special shape of tartary buckwheat (ovate with three edges), the shelling rate of this method is and the whole kernel rate are very low, and the nutritional content of tartary buckwheat is seriously lost

Embodiment approach 1

[0030] Embodiment 1: A cone type tartary buckwheat hulling device

[0031] Such as figure 1 It is a conical tube type tartary buckwheat hulling device, comprising a frame 26, a conical grinding cylinder 26a is vertically fixed in the middle of the frame 26, and a conical grinding roller 8 is concentrically installed inside the conical grinding cylinder 26a; There is a gap of 1 to 4 times the diameter of the shelled grain between the cylinder 26a and the inner conical grinding roller 8, and the gap gradually decreases from top to bottom at the conical portion of the conical grinding cylinder 26a. The inner wall of the conical grinding cylinder 26a has a grinding cylinder abrasive layer 9; the conical grinding roller 8 has a grinding roller abrasive layer 27; the cylindrical surface and the conical surface of the conical grinding roller 8 also have a grinding roller spiral 9a , the rotation direction of the grinding roller spiral 9a cooperates with the rotation direction of the...

Embodiment approach 2

[0040] Embodiment 2: A method of using a cone type tartary buckwheat shelling device

[0041] Pour tartary buckwheat grains with appropriate moisture content from the feed hopper 2, and control the feed flow rate through the feed valve 1. After the grains pass through the feed valve 1, they fall into the gap between the conical grinding roller 8 and the conical grinding cylinder 26a. The gap is large at the top and small at the bottom, so that the material forms a certain accumulation in the gap, and falls under the action of gravity as a whole; during the falling process of the material, the abrasive layer on the surface of the conical grinding cylinder 26a and the conical grinding roller 8 grinds the material shell , so that the husks at the corners are worn away and gradually become white (the kernels at the corners leak out), and the bonding strength of the husks of the grains is greatly reduced. During the grinding process, the grinding roller spiral 9a on the roller surf...

Abstract

The invention discloses a cone cylinder type tartary buckwheat dehulling device, which comprises a machine frame, wherein the middle part of the machine frame is vertically and fixedly provided with a cone mill cylinder, the interior of the cone mill cylinder is concentrically provided with a cone mill roller, the top of the cone mill cylinder is provided with a feeding hopper, a receiving hopper and a dehulling cylinder are sequentially arranged just below the cone mill cylinder and are fixedly arranged on the machine frame, the interior of the dehulling cylinder is concentrically provided with an iron roller with screws, a material flowing groove is arranged under the dehulling cylinder, a material outlet valve, a material outlet and a material receiving box are arranged under the material flowing groove, the upper part of the material outlet is connected with a vertical hull discharge pipeline, and the upper part of the hull discharge pipeline and a light slag pipe from the receiving hopper are connected into a fan. The device has the advantages that the dehulling rate and the whole kernel rate are higher; the structure is simple; and the device is suitable for the dehulling operation of grains, especially tartary buckwheat.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a device for shelling grains, especially tartary buckwheat. Background technique [0002] Tartary buckwheat has excellent nutritional value. my country is a big tartary buckwheat planting country. The annual production of tartary buckwheat reaches thousands of tons. Complete tartary buckwheat kernels can ensure sufficient nutrition of tartary buckwheat and obtain better market value. However, the current shelling machines at home and abroad adopt the ripening and shelling technology, which is cooked by boiling or microwave heating, and then shelled. Due to the special shape of tartary buckwheat (oval shape with three edges), the shelling rate of this method is very high. The rate of whole kernels and whole kernels is very low, and the nutritional components of tartary buckwheat are seriously lost. Contents of the invention [0003] Aiming at the problems and deficiencies in ...
