Problems solved by technology

[0002] Rice is the main food for Chinese residents. The current rice processing method is to directly use dried raw materials for processing, instead of directly transporting the harvested rice to the production line for drying and subsequent processing, which seriously affects the rice processing. The production efficiency of rice, the retention of a large amount of wet rice also requires a large amount of rice drying and storage space, which increases the requirements for planting and processing sites; in addition, during the drying process of rice, new impurities will be added, which will increase the burden on rice processing equipment , reducing its service life

Embodiment 1

[0025] A rice processing technology, comprising the following steps: primary screening→drying→secondary screening→cleaning→husking→separation of paddy and rough rice→rice milling→primary grading→polishing→sieving→color sorting→measurement packaging and storage.

[0026] Primary screening: The freshly harvested rice is directly passed through the blower to remove light impurities such as weeds and dust, and at the same time reduce its water content.

[0027] Drying: The rice after primary screening is first sent to a hot air dryer for drying at 40°C until the moisture content is 15%, and then the rice after hot air drying is sent to a microwave drying equipment for drying Until its moisture content is 12%, the working temperature of the microwave drying equipment is 50°C. The rice is dried by microwave through the microwave drying equipment, which can increase the soluble amylopectin content of the rice, so that the rice processed by this processing technology has a good taste....

Embodiment 2

[0039] The processing method of this embodiment is consistent with the process of embodiment 1, but the working temperature of the hot air dryer is 50°C, and the working temperature of the microwave drying equipment is 45°C. After the rice is dried, the water content of the rice reaches 13%.

Embodiment 3

[0041] The processing method of this embodiment is consistent with the process of embodiment 1, but the working temperature of the hot air dryer is 48°C, and the working temperature of the microwave drying equipment is 47°C. After the rice is dried, the water content of the rice reaches 13%.

Abstract

The invention relates to a processing technique for rice. The processing technique comprises the following steps of preliminary screening, drying, secondary screening, cleaning, unshelling, husked rice separation, rice milling, preliminary classification, polishing, screening, color sorting, metering, packaging, warehousing and storing. The drying process comprises the following specific steps of firstly, feeding preliminarily-screened rice into a hot air dryer, and performing drying treatment at the temperature of 40 to 45DEG C until the water content is 15 to 18 percent; and secondly, feeding the rice subjected to hot air drying into microwave drying equipment for performing drying treatment until the water content is smaller than 13 percent. According to the processing technique disclosed by the invention, a drying mode combines a hot air drying method with a microwave drying method, so that the cost of production equipment is reduced and the production efficiency is improved; and more importantly, the content of soluble amylopectin of the rice can be increased, and the rice is enabled to obtain good mouthfeel.

Description

technical field [0001] The invention relates to the field of rice processing, in particular to a rice processing technology. Background technique [0002] Rice is the main food for Chinese residents. The current rice processing method is to directly use dried raw materials for processing, instead of directly transporting the harvested rice to the production line for drying and subsequent processing, which seriously affects the rice processing. The production efficiency of rice, the retention of a large amount of wet rice also requires a large amount of rice drying and storage space, which increases the requirements for planting and processing sites; in addition, during the drying process of rice, new impurities will be added, which will increase the burden on rice processing equipment , reducing its service life. Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiency, provide a kind of rice processing technology t...
