Method for processing active rice

Abstract

The invention discloses a method for processing active rice, comprising the following steps: placing clean fresh grains into a drier, and heating the clean fresh grains by hot humid air the temperature of which is 40DEG C-60DEG C and the relative humidity of which is 75%-90% so as to increase the temperature of the clean fresh grains to 20 DEG C-30 DEG C and enable the weight percentage of water in the clean fresh grains to be 18%-22%; then feeding the clean fresh grains into a ventilating bin to be resuscitated for 30h-100h; placing the resuscitated active fresh grains into the drier and drying the resuscitated active fresh grain by hot wind the temperature of which is 40DEG C-60DEG C so that the resuscitated active fresh grains get into dry active fresh grains and the weight percentage of the water therein is 13%-15%; cleaning, husking and sorting cargo rice; performing thermal refining on the cargo rice and controlling the weight percentage of the surface layer moisture to be 14.5%-16% and the weight percentage of the interior moisture to be 13-15%; carrying out 9 polishing procedures for polishing the grains, wherein according to the processing sequence, the polishing pressure ratio of a rice mill is 6:5:4:3.5:3:2.5:2:1.5:1, and the prepared active rice has the embryo rate of more than 80%; and finally vacuumizing the active rice to obtain a finished product of the active rice.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to the technical field of grain processing, in particular to a processing method of active rice. Background technique [0002] At present, the drying of rice mainly adopts two methods of dryer drying and natural drying, the purpose of which is to reduce the moisture of rice to meet the requirements of storage or processing. The dried rice is husked and milled to make rice, or further made into germ rice and germinated rice. During the rice milling process of rice, most of the rice also removes the germ when the cortex is removed. [0003] Studies in recent years have found that the embryo can grow into a new life after germination, and it is a dynamic tissue. Although the mass of the embryo only accounts for 3% to 4% of the rice grain, it is rich in nutrients needed for life movement and many organisms. active ingredient. Chinese patent CN200410029666.6 discloses a germin...

Problems solved by technology

Although this invention can prepare rice with germ, its disadvantage is that the germ content of rice with germ is low, only 40%; secondly, microwave drying is used, and the power consumption is large, which is not conducive to industrial production

But the disadvantage is that the process is too simple, there is no quenching and tempering process, and the embryo retention rate cannot be guaranteed to reach more than 80%.

[0004] Although the processing methods of rice with germination and germinated rice can retain the embryo of rice, there are also shortcomings: the processing method and process control of rice with germination are relatively complicated, and it is not easy to ensure the retention of embryos; Germination, dehydration and re-drying require a large space and consume a large amount of water, which is not suitable for large-scale industrial production
