Embodiment 3

[0027]Application of the present invention in microwave enzyme inactivation and drying wheat germ: fresh wheat germ enters the conveyor belt 6 through the feeder 1, and the wheat germ enters evenly by adjusting the number of revolutions of the feeder 1 and the transmission speed of the conveyor belt Conveyor belt 6 and keep the material layer uniformly paved into a 1cm thick layer to ensure uniform heating. Turn on the microwave generator 3 for microwave heating to kill enzymes and microwave drying at the same time. The rated power of the microwave tunnel is 2kW, and the processing capacity is about 40kg of wheat germ per hour. The wheat germ passes through the microwave tunnel 2 at a uniform speed under the drive of the conveyor belt 6, and has obtained enzyme-killing and drying treatments. Layer, which is convenient for the timely distribution of hot and humid air generated during microwave heating and ensures uniform heating of the material layer. Finally, measure the moistu...

Abstract

The invention provides a continuous synchronous microwave enzyme inactivation and drying device and method for grain germ, relating to the agricultural product drying field. The device comprises a microwave tunnel (2), a microwave generator (3) and a conveyer belt (6) and also comprises a feeder (1) and a germ overturning device (5); wherein the microwave generator (3) is arranged at the top of the microwave tunnel (2), the feeder (1) is arranged at the initial end of the conveyer belt (6), and the revolution of the feeder is adjustable; the conveyer belt (6) is connected with the feeder (1) and the microwave tunnel (2) to convey materials through the microwave tunnel (2), and conveying speed is adjustable; and the germ overturning device (5) is arranged on the conveyer belt (6). The watercontent of the grain germ through microwave enzyme inactivation and drying of the invention can be reduced to 1.9-4.4%; microwave treatment is carried out on different grain germs, the grain germs can be preserved for 6-8 months at normal temperature in winter and for 3-5 months at normal temperature in summer, quality requirement of follow-up processing can still be met, and the invention is widely applicable to enzyme inactivation and drying of grain germs such as wheat germ, corn germ, rice germ (rice bran) and the like.

Description

technical field [0001] The invention relates to the field of drying agricultural products, in particular to a device and method for continuous and synchronous microwave enzyme inactivation and drying of grain germ. Background technique [0002] Although the grain germ only accounts for a small part of the grain, it is rich in protein, fat, minerals and vitamins, and has high nutritional value. Take rice bran as an example: when brown rice is whitened, the mixture of the epidermis of rice grains (endosperm), rice germ and a small amount of broken endosperm (broken rice, rice bran) is usually called rice bran. Although the weight of rice bran is less than 10% of that of brown rice, the important nutrients of brown rice are concentrated in a large amount in rice bran. Rice bran contains 12% to 16% protein, 12% to 23% fat, 8% to 10% crude fiber and 7% to 12% ash. In addition, it is also rich in vitamins and minerals, and at least 78% of the VB in brown rice is concentrated 1 ,...
