Embryo grain separation device for rice processing process

Abstract

The invention relates to the field of rice processing machinery, and discloses an embryo grain separation device for a rice processing process. The embryo grain separation device comprises a separation tank; a vibration generator is fixed on the separation tank; a liquid inlet pipe is arranged on the side wall of the separation tank; a discharging port and a guide plate are arranged in a notch of the separation tank; a cylinder is fixed in the notch; a push plate is mounted at a free end, towards the discharging port, of the cylinder; a discharging hole is formed in the lowest place of the concave surface of the bottom of the separation tank; a valve is mounted in the discharging hole; a netty conveying belt is mounted below the valve; a ventilation pipe is above the conveying belt; a ventilation hole is formed in the ventilation pipe, and is towards the conveying belt; one end of the ventilation pipe is closed, and the other end communicates with an air blower; and a heating device is arranged in the ventilation pipe. The invention aims to provide the embryo grain separation device for the rice processing process; and the embryo grain separation device separates embryo grains from bran shells in the rice processing process, and guarantees the embryo grains to be not deteriorated caused by oxidic rancidification in the separation process.

Description

technical field [0001] The invention relates to the field of rice processing machinery, in particular to a germ grain separation device used in the rice processing process. Background technique [0002] Rice is processed from rice. Rice is usually composed of seed coat, pericarp, aleurone layer, endosperm and embryo. The embryo usually forms light yellow particles, which are located on the endosperm of the lower belly of the rice. Although the quality of the embryo only accounts for the whole rice 2%-3.5% of the mass, but the embryo is rich in fat, protein and vitamins, etc., and has high nutritional value. However, the embryo contains a large amount of fat that is prone to oxidative rancidity, and if it is in contact with the air for too long, it is prone to oxidative rancidity and deterioration. [0003] Because there is a layer of scutellum between the embryo and the endosperm, the connection between the embryo and the endosperm is not firm. In the process of rice proce...

AI Technical Summary

Problems solved by technology

However, the embryo contains a large amount of fat that is prone to oxidative rancidity, and if it is in contact with the air for too long, it is prone to oxidative rancidity and deterioration.

[0003] Since the embryo and endosperm are separated by a layer of scutellum, the connection between the embryo and endosperm is not firm

In the process of rice processing, the embryo is easily crushed from the endosperm by the rice mill to form the germ, and is sorted by the sorting device on the rice mill into the rice bran discharge port, and is discharged together with the bran shell as a by-product. It will be discarded together with the bran husk, causing a serious loss of the nutritional value of the rice and also causing waste

The existing rice processing system does not have a separation and recovery device for germ kernels with extremely high nutritional value, and ensures that the germ kernels will not be oxidative and rancid during the separation process.
