Abstract

The invention discloses a processing technology of preboiled rice. The processing technology comprises the following specific steps: rice cleaning; soaking: heating the water temperature to 40 to 50 DEG C, pressurizing to 0.4 MPa, adding the cleaned rice, soaking for 40 minutes, regulating the water temperature to 30 to 40 DEG C, and regulating the pressure to 0.15 to 4 MPa until the rice water absorption is up to 36 to 38 percent; cooking; drying treatment; husking and rice milling; polishing; color sorting: removing a small amount of black-colored rice, black head rice and yellow-colored rice mixed in finished rice, thus obtaining the preboiled rice through processing. The processing technology disclosed by the invention has the advantages that the technology is simple, the processing quality is high, and the like.

Description

technical field [0001] The invention relates to the technical field of parboiled rice processing, in particular to a parboiled rice processing technology. Background technique [0002] Parboiled rice, also known as semi-cooked rice, is a pure natural and nutritious rice made of Chinese indica rice as raw material, after cleaning, soaking, cooking, drying and other hydrothermal treatments, and then shelling and milling according to conventional methods. Generally, pollution-free, green and organic rice is used to ensure that unfavorable ingredients such as pesticide residues and heavy metals are not immersed in it. Parboiled rice is not widely known in China, but it is very popular in Europe, America, the Middle East and other regions. It is famous abroad as healthy rice and green food. The selling price of parboiled rice in the international market is usually 10%-5% higher than that of white rice of the same specification. Significant benefits. [0003] Regarding the origi...
