Embodiment 1

[0014] A kind of paddy rice retaining nutrient source technology, comprises the following steps:

[0015] Step 1: First, use the initial cleaning sieve to remove large impurities in the rice, such as stalks, hemp ropes, stones, paper pieces, etc.; after the initial cleaning sieve, lift it to the plane cleaning sieve to clean the rice granular materials The size and light impurities; then lift the de-stoner machine, the purpose is to separate the side stones and other impurities larger than the rice from the rice;

[0016] Step 2: Then the paddy after the initial cleaning in the first step is lifted to the huller to remove the chaff and make brown rice, which reduces the bursting of rice grains and surface damage, keeps the integrity of brown rice, and improves the rice processing efficiency. Whole rice rate; then lift the brown rice to the single sieve to clean up the sundries again to prevent the sundries from entering the rice milling room; then lift the brown rice to the th...

Embodiment 2

[0020] The first step-the second step is the same as embodiment 1;

[0021] The third step: upgrade to the intelligent rice mill with germ retention, one light mill to peel off the bran layer, two light mills to peel off the bran layer, three light mills to peel off the bran layer, four light mills to retain the germ and aleurone layer; one parameter The settings are: the temperature of the rice milling room is controlled at 3°C, the efficiency is 1000kg / h, the upper and lower limit of the knife holder is 0.02mm, the gap between the rice knife and the abrasive belt is 12.02mm, and the abrasive belt is 200*3000mm (80#) to peel off the bran layer by layer; The road parameters are set as follows: the temperature of the rice milling room is controlled at 3°C, the efficiency is 1000kg / h, the upper and lower limit of the knife holder is 0.02mm, the gap between the rice knife and the abrasive belt is 11.02mm, and the abrasive belt is 200*3000mm (120#) to peel off the bran layer by lay...

Embodiment 3

[0024] The first step, second step are with embodiment 1;

[0025] The third step: upgrade to the intelligent rice mill with germ retention, one light mill to peel off the bran layer, two light mills to peel off the bran layer, three light mills to peel off the bran layer, four light mills to retain the germ and aleurone layer; one parameter The settings are: the temperature of the rice milling room is controlled at 6°C, the efficiency is 1000kg / h, the upper and lower limit of the knife holder is 0.04mm, the gap between the rice knife and the abrasive belt is 12.02mm, and the abrasive belt is 200*3000mm (80#) to peel off the bran layer by layer; The road parameters are set as follows: the temperature of the rice milling room is controlled at 6°C, the efficiency is 1000kg / h, the upper and lower limit of the knife holder is 0.04mm, the gap between the rice knife and the abrasive belt is 11.02mm, and the abrasive belt is 200*3000mm (120#) to peel off the bran layer by layer , the...

Abstract

The invention relates to a technology for reserving a nutrient source of germ-remaining rice. The problem that the large number of natural nutrition ingredients of the rice are prone to running away by adopting a traditional technology is mainly solved. The technology is characterized by comprising the following steps that (1), impurities of the rice are cleared away firstly; (2), glumes are further taken off from the rice, the impurities and immature green grains are cleared; (3), the rice treated through the step (2) is lifted to a first-time slight-milling bran-stripping layer, a second-time slight-milling bran-stripping layer, a third-time slight-milling bran-stripping layer, a fourth-time slight-milling germ-remaining layer and an aleuron layer of an intelligent germ-remaining and rice-milling machine; and (4), through treatment, the germ-remaining rice is uniform in size and length, complete in condition and unified in grade. According to the technology for reserving the nutrientsource of the germ-remaining rice, the natural nutrition ingredients of germs and the aleuron layer of the nutrient source can be reserved, and the milled rice rate is high.

Description

technical field [0001] The invention relates to the technical field of rice industry processing, in particular to a process for retaining nutrient sources of rice with germination. Background technique [0002] There is a lot of knowledge about the rice we eat every day. The nutrition of a grain of rice is concentrated in a small yellow spot, which is the small yellow spot that breeds life. The so-called "bud" is the part that gives birth to new life, called the germ. The weight of the germ only accounts for about 3% of a grain of rice, but it contains 66% of the nutrition of the whole grain of rice. It contains protein, unsaturated fatty acids, B vitamins, vitamin E, zinc and other essential nutrients for 90% of the human body, and is known as the "source of nutrition given by God". Aleurone is the innermost layer of the seed cortex of cereal crops, located between the seed coat and endosperm, accounting for 7% to 9% of the total seed mass, but contains 29% of the nutrien...
