Problems solved by technology

However, in the large-scale microwave heating with a large amount of material to be processed, the moisture of the surface material volatilizes quickly and the temperature rises slowly, while the moisture of the inner layer material is not easily volatilized due to the barrier, which will increase the local moisture content, and the heating effect of microwave heating is high.
The current microwave heating uses far-infra

Embodiment 1

[0030] Weigh rice bran powder with a water content of 10%, pass through a sieve, and take the 40-mesh sieve, and spray clean water while stirring in a mixer at 700-1000 rpm. The amount of water sprayed makes the water content of rice bran reach 18%, continue stirring to make the rice bran evenly hydrated. Enter the microwave reactor, adjust the microwave power, and raise the temperature to the set 70°C within 60 seconds. Using a conveyor belt, the rice bran is transported to the far-infrared heating section that has been heated to 80°C, where it is heated and kept for 15 minutes. Continue to carry out the next section of microwave heater through the conveyor belt, and heat while conveying on the conveyor belt. The temperature of this section is set at 90 ° C. After heating for 200 seconds, the conveyor belt is sent to the air conveyor for transmission and cooling. Then pass through a 40-mesh sieve, and the oversize is returned to the pulverizer for re-grinding, and the unders...

Embodiment 2

[0032] Weigh rice bran powder with a water content of 10%, pass through a sieve, and take the 40-mesh sieve, and spray clean water while stirring in a mixer at 700-1000 rpm. The amount of water sprayed makes the water content of rice bran reach 30%, continue stirring to make the rice bran evenly hydrated. Enter the microwave reactor, adjust the microwave power, and raise the temperature to the set 80°C within 300 seconds. Using a conveyor belt, the rice bran is transported to the far-infrared heating section that has been heated to 90°C, where it is heated and kept for 8 minutes for reaction. Continue to carry out the next section of microwave heater through the conveyor belt, and heat while conveying on the conveyor belt. The temperature of this section is set at 100 ° C. After heating for 50 seconds, the conveyor belt is sent to the air conveyor for transmission and cooling. Then pass through a 40-mesh sieve, and the oversize is returned to the pulverizer for re-grinding, a...

Embodiment 3

[0034] Weigh rice bran powder with a water content of 10%, pass through a sieve, and take the 40-mesh sieve, and spray clean water while stirring in a mixer at 700-1000 rpm. The amount of water sprayed makes the water content of rice bran reach 25%, continue stirring to make the rice bran evenly hydrated. Enter the microwave reactor, adjust the microwave power, and raise the temperature to the set 75°C within 180 seconds. Using a conveyor belt, the rice bran is transported to the far-infrared heating section that has been heated to 86° C., where it is heated and kept for 1.5 minutes. Continue to carry out the next section of microwave heater through the conveyor belt, and heat while conveying on the conveyor belt. The temperature of this section is set at 95 ° C. After heating for 120 seconds, the conveyor belt is sent to the air conveyor for transmission and cooling. Then pass through a 40-mesh sieve, and the oversize is returned to the pulverizer for re-grinding, and the un...

Abstract

The invention discloses an enzyme-deactivation stabilizing treatment method of rice bran. According to the stabilizing treatment method, by combining a rapid microwave heating manner with an efficient far-infrared temperature control manner, the disadvantage that although the temperature increase is rapid, the temperature is difficult to stabilize and control in a microwave heating manner is overcome, and microwave and far-infrared heating energy-saving techniques are truly applied to the production field of enzyme deactivation of rice bran. According to the stabilizing treatment method, the residual activity of peroxidase of rice bran which is subjected to enzyme-deactivation stabilization is 1.1%, and after the rice bran is cultured in a constant-temperature incubator at 37 DEG C for 60 days, the free fatty acid value of the stabilized rice bran is always stabilized at 140mgKOH/100g-170mgKOH/100g; the microwave heating technique and the far-infrared heating technique are two excellent energy-saving heating techniques and are applied to the industrial production of stabilization of rice bran, so that the purposes of high efficiency, energy saving, emission reduction and consumption reduction are achieved; by combining the microwave heating technique and the far-infrared heating technique, the disadvantages of the single microwave heating manner that the temperature is difficult to control, and the product quality is instable are overcome.

Description

technical field [0001] The invention relates to the technical field of agricultural by-product processing, in particular to a rice bran enzyme-inactivating and stabilizing treatment method. Background technique [0002] Rice bran is a by-product of rice processing. It is a mixture of cortex and a small amount of rice germ produced during brown rice milling. It is a renewable resource with a large amount and a wide range. The United Nations Industrial Development Organization (UNIDD) calls rice bran an underutilized raw material. According to the research report of the United States Department of Agriculture, 64% of the nutrients in rice are concentrated in rice bran, which is a valuable resource for the development of rice bran oil, rice bran health food and various biologically active substances. my country's annual output of rice is about 200 million tons, and it is the world's largest rice-producing country. The quality of rice bran accounts for about 7.5% to 8.0% of ric...
