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...
