Device for brown rice deinsectization enzyme

Abstract

The invention relates to a device for brown rice deinsectization enzyme. The device comprises a treating cabin, a feeding hole and a discharging hole, wherein the feeding hole is formed in the treating cabin; the discharging hole is formed on a side which corresponds to the feeding hole in the treating cabin; a transport tape positioned below the feeding hole is arranged in the treating cabin; a material falls off from the feeding hole, and is fed to the discharging hole through the transport tape; vent holes are distributed in the transport tape; a plurality of air inlets which are formed tightly along the conveying direction of the transport tape are formed below the transport tape; overheated steam generated by an overheated steam generator and hot air generated by an air heater are conveyed to each air inlet through an air pump and a pipeline, reach the material through the vent holes, and is discharged from the air outlets; overheated steam and hot air are introduced into adjacent air inlets respectively; and gas discharged from adjacent air inlets is isolated by a clapboard after passing through the vent holes. Due to the adoption of the device disclosed by the invention, worms, molds and bacteria in brown rice can be killed efficiently, and lipolytic enzymes such as lipoxidase and lipase in brown rice are passivated; and alternative treatment is performed through overheated steam and air, so that cracked rice of brown rice can be prevented.

Description

technical field [0001] The invention relates to a grain processing device, in particular to a device for disinsection enzymes for brown rice. Background technique [0002] Low-temperature storage and vacuum packaging are commonly used for rice storage at home and abroad. Low temperature storage can only delay the quality deterioration of rice to a certain extent, and the input and maintenance costs are relatively high. Vacuum packaging works well, but the rice will still oxidize slowly under the action of enzymes, and the hidden eggs in the rice grains cannot be eradicated. [0003] At present, the rice enzyme inactivation methods mainly include ethanol treatment, organic solvent extraction, irradiation treatment and heat treatment. However, the residues of chemical reagents and the safety of irradiation are not conducive to the stability of rice quality. Conventional heat treatment takes a long time, which will easily cause the loss of rice nutrients. The use of superhe...
