Puffing device for brown rice food processing

Abstract

The invention relates to a puffing device for brown rice food processing. The puffing device comprises a puffing structure, a heat insulation structure and a metering structure; wherein the heat insulation structure is mounted in the puffing structure, and the metering structure is mounted on the puffing structure; wherein the puffing structure is used for quickly puffing brown rice and pushing the puffed brown rice out of the puffing structure; so that the brown rice is heated more uniformly, meanwhile, a transmission packing auger is driven to rotate through a positive and negative rotation motor, so that the brown rice is driven to be transmitted, the brown rice is heated more uniformly, the puffing speed of the brown rice is increased, the puffed brown rice is sent out of a stirring tank through the transmission packing auger after heating is completed, workers can take the puffed brown rice conveniently, there is no open fire generated by heating through an annular heating pipe, the puffing device is relatively safe, environmental pollution is reduced, heat can be isolated through a heat preservation tank and a heat insulation layer, a human body can be prevented from being scalded by high temperature.

Description

technical field [0001] The invention relates to the field of food processing, in particular to an extruding device for brown rice food processing. Background technique [0002] Brown rice is the rice grain that still retains the cortex and germ after the rice is shelled. Compared with rice, it not only contains more protein, fat, vitamins, minerals and other nutrients, but more importantly, it also contains dietary fiber, oryzanol, and glutathione. Glycine, γ-aminobutyric acid, rice bran polysaccharide, octacosanol, inositol and many other functional factors that promote human health. Brown rice needs multiple processes in the process of processing, and the puffing of brown rice is a process of brown rice food processing. [0003] Most of the existing brown rice puffing devices use sealed steel tanks to puff brown rice, put certain materials into a sealed cast steel tank with a cover, use liquefied petroleum gas, coal gas or coal to heat, and continuously rotate at a cert...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing brown rice puffing devices use sealed steel tanks to puff brown rice, put certain materials into a sealed cast steel tank with a cover, use liquefied petroleum gas, coal gas or coal to heat, and continuously rotate at a certain speed The tank body heats the material evenly. With continuous heating, the temperature in the tank gradually rises. When it reaches above 100°C, the moisture in the surface and body of the material will overflow and vaporize, and a certain pressure will be formed in the tank to make the brown rice ripen. When processing with this kind of puffing method, it is necessary to use gas or coal to heat, and an open flame will be generated during heating, which is unsafe and causes relatively large environmental pollution.
