Method and step for measuring pure milled rice rate using rice grinder
There are many items for food testing, including not only the determination of moisture, but also the determination of the rate of pure polished rice. The measuring instrument is mainly rice milling machine. Its role is to grind rice into polished rice and then test the yellow grain, disease class, belly white. And imperfect grains to judge the quality of rice. At present, the use of polished rice in the detection of rice is becoming more and more widespread, and many people have a certain understanding of it. But when it comes to the method of using rice to measure the rate of pure rice, many people may not be able to answer it. To increase everyone's understanding of rice milling machine, here's how to use rice milling machine to detect the rate of pure rice in rice.
1. Samples In order to ensure the accuracy of the test results, the first is to sample, according to the sample operation method, to take samples 150g (W);
2. After the miller grinds and removes the sample, it can be milled using the rice miller. At this time, the rice miller has played its fast and high-efficiency characteristics. It only takes 60 seconds for the rice to be stored in the acquisition and site. Can finish whitening work.
3. Screening and taking out the sample, pour it into a sieve of grains (2.5mm), and use the hands on the glass plate or a smooth tabletop to rotate clockwise and counterclockwise by a few degrees per minute 110 to 120 times for 1 minute. (The range of sieving is controlled by the diameter of the filter being enlarged by 8 to 10 cm.);
4. Remove miscellaneous Impurities such as rice husks from the screen are blown and weighed (W1).
5. Weighing and then quartering method to take a sample weight (W1) 20g;
6. Pick up the bad pellets and weigh and count the chalky, broken rice, uncooked, diseased, worm-eaten, and yellow rice from the 20 g sample and weigh the remaining whole rice (W2) . Final calculation.
Although the rice milling machine is only one of the applications in determining the rice milled rice rate, its role is undoubtedly true. Only by using the rice milling machine to complete the whitening work, can we ensure that the following work continues to be carried out and can meet the rice well Acquisition, rice processing and other departments to determine the quality of rice requirements.
Castor Oil Ethoxylates are a type of nonionic vegetable oil ethoxylate based on castor oil, which is composed of traditional fatty acids. They have unique physical properties that allow usage as versatile emulsifiers, solubilisers, emollients, dispersants, and lubricants in various market segments including personal care, home care and agrochemicals.
