A kind of high-efficiency and energy-saving rice vermicelli preparation method

Abstract

The invention provides a high-efficiency energy-saving rice vermicelli preparation method which comprises the following steps: (1) removing impurities from rice and whitening; (2) drily grinding part of rice into dry rice flour; (3) adding water into the rest of rice for soaking and then grinding into rice milk; (4) dewatering the rice milk to obtain wet rice flour; (5) mixing the dry rice flour, the wet rice flour and a texture modifying agent to obtain rice vermicelli; (6) leading in steam so as to gelatinize rice vermicelli; (7) extruding primarily steamed rice vermicelli into long strips, and then extruding the long strips to obtain rice vermicelli; (8) steaming the rice vermicelli to be gelatinized and then cutting into rice vermicelli blocks; (9) drying the rice vermicelli blocks until moisture content is below 13.0wt%; (10) packaging to obtain finished products. By combining wet grinding and dry grinding of the rice, the rice soaking and grinding time can be obviously shortened, the grinding energy consumption can be decreased, and the production efficiency of the rice vermicelli can be increased; by adopting a vacuum-hot air drying method, the drying time of the rice vermicelli can be shortened, and the crushed rice vermicelli rate, the rice vermicelli breakage rate and the bubbling rate of the rice vermicelli can be reduced.

Description

technical field [0001] The invention relates to a method for preparing rice vermicelli, in particular to a method for preparing rice vermicelli with high efficiency and energy saving. Background technique [0002] Rice vermicelli is a traditional delicacy in my country. It has a long consumption tradition and a broad market in China. Its production areas are mainly distributed in South China and Southwest China such as Guangdong, Guangxi, Hunan, Hubei, Yunnan, and Guizhou. One of the reasons why rice vermicelli is so popular among consumers is that it is cheap and suitable for the consumption level of ordinary people. In recent years, with the rapid increase in the prices and expenses of raw materials and labor for rice vermicelli processing, the competition in the rice vermicelli processing industry has intensified, and the phenomenon of inversion between the cost of rice vermicelli and the sales price is very obvious. Cost has become the key to the survival of enterprises...

AI Technical Summary

Problems solved by technology

[0003] At present, rice vermicelli is generally processed by wet milling method, and dry milling method is rarely used, because the damaged starch content in the rice flour produced by dry milling method is higher than that by wet milling method, resulting in the quality of processed rice vermicelli products. Difference

In addition, the drying of rice vermicelli mainly adopts the method of steam drying and hot air drying at present, which is a process of high energy consumption, which urgently needs to be overcome.
