Clean rice dregs formed by milling embryo and aleurone layers and production technology thereof

Abstract

The invention discloses clean rice dregs formed by milling embryo and aleurone layers and a production technology thereof and belongs to the technical field of rice deep processing technology. The technology related in the invention comprises two processes, and six or more machines are adopted for milling rice, wherein three or more machines discharge dregs. The washing-free rice with embryo and aleurone layers produced by a washing-free rice production process is further subjected to a rice dreg milling process, wherein a sand roller of one machine performs milling, and iron rollers of two or more machines performs milling and polishing to realize the technology and produce clean rice dregs in which the content of the embryo and aleurone layers is greater than 60% and the residue of peels, seed coats and perisperms is less than 1%. According to the invention, the embryo and aleurone layers abandoned by people used to eating high milled rice, namely rice dregs contained in rice bran, are turned into wealth; and clean natural nutrient healthcare food is directly extracted from the rice milling technology by use of the modern precise rice milling technology so that the internal values of the rice dregs are sufficiently used, the grain resources are saved and relatively high economic and social benefits are realized.

Description

technical field [0001] The invention discloses a clean rice meal made by grinding embryos and aleurone layers and a production process thereof, which belong to the technical field of deep processing of rice. Background technique [0002] Rice is the staple food of human beings and the main source of nutrition for the basic energy and nutritional needs of the human body. my country's output ranks first in the world, accounting for 33% of the global total output. The primary processing state, the product structure is single, and the level of comprehensive utilization of by-products is lower. As the main by-product, rice bran is about 20 million tons per year in my country. It has not been effectively used, and it has been severely corroded and rancid by microorganisms. Only a small part is used for oil production, and most of it is used for feed and spoilage. While the benefit is low, it also causes a lot of environmental pollution. [0003] Rice bran is made from rice peel, s...

Problems solved by technology

[0004] In the past, the rice-making technology was not advanced enough, and the sterilization and antibacterial fresh-keeping measures were backward. The embryo and aleurone layer could only be discarded as by-products, and people got used to eating polished white rice. , the promotion of No. 98118213.5 patented product Wutaomi has always been difficult
