Processing production line for long-storage light-grinding enriched rice

Abstract

The invention relates to a processing production line for long-storage light-grinding enriched rice. The processing production line comprises a stoning machine, a rice huller, a rice-unpolished rice separator, a steam treatment system, a light grinding system, a color selector and a packaging device; the steam treatment system comprises a tempering box, a charging hole, a discharging hole, conveyor belts, a hot air square tube, a cold air square tube and a pressure relief opening, wherein the charging hole and the discharging hole are arranged in the tempering box; the conveyor belts are arranged in the tempering box; the hot air square tube and the cold air square tube are arranged below the conveyor belts; the pressure relief opening is arranged in the tempering box; five layers of conveyor belts are arranged in the tempering box and are arranged in a staggered manner; and the unpolished rice is transmitted from the front ends of the first layer of the conveyor belts to the tail ends of the first layer of the conveyor belts, and drops to the front ends of the next layer of the conveyor belts, so as to get through the five layers of the conveyor belts in sequence and be fed out from the discharging hole. The processing system can simultaneously produce long-storage enriched rice and rice bran, and has such advantages as high efficiency, and environment friendliness; and moreover, the amount of produced broken rice is low, and the generality is good.

Description

technical field [0001] The invention relates to a grain processing production line, in particular to a storage-resistant lightly milled nutritious rice processing production line. Background technique [0002] With the improvement of living standards, people pay more and more attention to healthy, nutritious and balanced diet. In Europe, America, Japan and other countries, brown rice with higher nutritional value is advocated. However, brown rice has not been widely accepted because it contains more crude fibers and bran layers, has poor expansibility and water absorption, and has a bad taste. However, after the light milling process of brown rice, the brown rice cortex can be removed, and the light milling nutritional rice that retains the aleurone layer and the germ can be obtained. Because lightly milled nutritious rice removes part of the bran layer, it tastes better than brown rice and contains more nutrients than polished white rice. However, after the bran layer is...

AI Technical Summary

Problems solved by technology

However, after the bran layer is removed, the aleurone layer in the rice grains is in direct contact with the air, resulting in easy oxidation and deterioration of lightly milled nutritious rice, which is not resistant to storage
