Description

Technical Field

[0001] The present invention relates to the separation of solid mixtures, and particularly to the separation of the mixture screened out during the processing of germinated brown rice. Background Art

[0002] During the processing of germinated brown rice, in addition to the products that people need, there are also by-products. Since there is no good method and equipment to completely separate the germ, this part of the germ has not been fully utilized, resulting in a loss of nutritional value. Summary of the Invention

[0003] Technical problem to be solved: Extract the germ with high purity.

[0004] Technical solution:

[0005] The devices mainly included in the present invention are: a material washing device, a drying device, and a color sorter.

[0006] The mixed material is added to the material washing device, water is added in the material washing device for stirring and cleaning, and after cleaning, the water is filtered out and discharged; the cleaned mixed material is added to the drying device; the dried mixed material is sorted by the color sorter to separate the germ, and the extraction of the germ is completed.

[0007] At the lower end of the washing cylinder in the material washing device, there is an annular filter screen, at the lower end of the annular filter screen, there is an annular seal, outside the annular filter screen, there is an annular cavity, and the drain port communicates with this annular cavity. The water filtered out by the annular filter screen can be discharged from the drain port through the annular cavity outside it and enter the sewage treatment device.

[0008] Below the spoke disc in the material washing device, there is a stirring rod. The stirring rod is located inside the washing cylinder and can rotate and stir inside it; when the spoke disc does not rotate, the material can be added into the washing cylinder through the gaps between the spokes.

[0009] The pull rod in the material washing device passes through the spoke disc. The axis of the pull rod coincides with the rotation axis of the spoke disc. The pull rod can slide relative to the spoke disc along its axis; the lower end of the pull rod is fixed to a conical plug. The conical surface of the conical plug cooperates with the annular seal. When the pull rod drives the conical plug to move downward, the conical plug separates from the annular seal, and the mixed material in the washing cylinder can be discharged and enter the drying device; when the pull rod drives the conical plug to move upward, the conical plug engages with the annular seal for sealing.

[0010] The water injection port on the water injection part in the material washing device is fixed on the annular pipe and communicates with the annular pipe. The water outlet holes are distributed circumferentially at the lower part of the annular pipe. The water coming out of the water outlet holes is added into the washing cylinder through the gap between the spoke disc and the washing cylinder. While the conical plug is opened to discharge the mixed material, water can be added simultaneously to assist in the discharge of the mixed material.

[0011] The conical screen in the drying device is fixed to the lower end of the upper drying cylinder and the upper end of the lower drying cylinder, and the mixed materials discharged by the material washing device are placed on this conical screen; there is an air outlet on the upper side of the upper drying cylinder, and a temperature and humidity sensor is arranged on the air outlet; there is a discharge port at the bottom of the conical screen, and the discharge port extends out from the lower drying cylinder; there is an air inlet on the lower side of the lower drying cylinder, and a drain port is arranged at the bottom. The excess water filtered from the mixed materials by the conical screen can be discharged from the drain port and enter the sewage treatment device.

[0012] The lower end of the annular seal in the material washing device is connected to the upper end of the upper drying cylinder in the drying device.

[0013] One end of the heating device in the drying device is connected to the air inlet, and the other end is connected to the blower. A temperature sensor is arranged at the connection of the heating device and the air inlet. The heating device heats the air blown out by the blower, and the temperature sensor feeds back the temperature of the air to closed-loop control the heating device and the blower. The heated air enters the lower drying cylinder from the air inlet, passes through the gaps of the mixed materials through the conical screen and then enters the upper drying cylinder, and heats and dries the mixed materials during this process. The hot air flowing through the mixed materials is discharged from the air outlet, and the temperature and humidity sensor at the air outlet monitors the temperature and humidity of the discharged air, and the temperature and humidity sensor feeds back the temperature and humidity of the air to closed-loop control the drying time.

[0014] The dried mixed materials enter the color sorter from the discharge port at the bottom of the conical screen to separate the germ.

[0015] Beneficial effects:

[0016] The germ is simply extracted from the by-products of germinated brown rice processing, and its nutritional value can be more fully developed and utilized; the structure of the germ extraction device is exquisitely designed, with high integration and small occupied volume; the extracted germ has high purity; and there is no pollution to the environment.
