Abstract
The invention discloses a rice processing method, which comprises the following steps: s1: harvesting the rice by using a combine harvester; s2: removing impurities and dust from the harvested paddy by using a cleaning machine, and drying the paddy by blowing; s3: hulling rice at normal temperature by using a huller, wherein the hulling rate is 85-90%, and obtaining brown rice; s4: storing the husked brown rice in a refrigeration house at the temperature of minus 17-22 ℃ to enable the paddy with high water content to be in a solid state; s5: removing bran from solid rice in a refrigeratory at-17 deg.C to-22 deg.C by rice mill, and discharging rice bran to obtain rice grains; s6: vacuum packaging the rice grains; s7: storing at low temperature in a refrigeration house at the temperature of minus 17-22 ℃; s8: the transportation adopts cold chain transportation. And a mature freezing technology is applied, so that the freshness of the rice grains is locked, and the original taste of the rice grains is kept.
Description
Technical Field
The invention relates to the technical field of grain processing, in particular to a rice processing method.
Background
Most people in China take rice as staple food, have the characteristics of delicious taste, special aromatic flavor, easy digestion and the like, and can be accepted by wide consumer groups. With the continuous progress of science and technology, rice processing methods are continuously perfected, so that the traditional rice is only obtained by peeling off rice husks to improve the rice smoothness, then to reduce the rice nutrition loss, reduce the broken rice rate and the like, at present, the rice processing method is shown in figure 1, firstly, a combine harvester is used for harvesting rice, removing impurities, natural airing or machine air drying, husking and bran removal are carried out, the water content of the rice to be milled is required to be lower than 18% for processing, otherwise, the rice can be removed to cause the blockage of a fine rice machine and cannot be processed, then, packaging and storage are carried out, the water content of the harvested and stored rice is required to be lower than 14.5% for normal-temperature storage, and the rice is transported according to actual transportation.
However, in any processing method, a rice dehydration process cannot be separated, the main reason is that the moisture content of the just-harvested rice is high, the rice is moldy without airing or drying, and the rice cannot be hulled and debranned, and in addition, in the rice processing process, friction is required to be generated between the rice and the rice, between the rice and the machine, and the like, so that the hulls on the surface of the rice can be peeled off, the rice is exposed, and the processing of the rice is completed; in the process, the processing temperature of the rice is often high, even up to 40 ℃, the freshness of the rice cannot be locked, the faint scent of the rice is lost, and the taste of the rice is influenced.
Based on the above, the researchers are based on the exploration of the rice processing method, and provide a new idea for rice processing.
