Problems solved by technology

[0003] In the actual production process, the broken rice rate in the rice obtained by the rice processing technology accounts for 15-30%. Due to the following two reasons, the broken rice rate will increase: the first is the various treatments before the rice processing, including the rice The state of harvesting, during the process of threshing, tumbling, loading and unloading machine transportation, etc., the rice is crushed by mechanical impact; the second is the process performance of rice processing machinery and equipment and operation management level, etc.

Embodiment 1

[0018] A processing technology of high-quality rice, comprising the following steps:

[0019] (1) impurity removal: put the harvested paddy into the impurity remover to remove impurities, and then spread it in the drying room;

[0020] (2) Dehumidification: use hot air to dry the paddy spread in the drying room multiple times, the hot air temperature is 35 ° C, take out and turn after every drying 50min, and dry after cooling for 10min, until the rice moisture content 15%, finally cooling the rice to room temperature;

[0021] (3) one-time rice milling: put the rice cooled to room temperature into a rice mill to remove the chaff, so that the hulling rate is 60%, and a semi-finished product is obtained;

[0022] (4) Wetting: atomize the semi-finished product to make the surface of the semi-finished product adhere to the water mist; put the atomized and wet semi-finished product into the steam of 300 ℃ and heat it for 2S and take it out;

[0023] (5) Drying: the semi-finished ...

Abstract

The invention discloses a processing technology of good-quality rice. The processing technology is characterized by comprising the following steps of impurity removal, drying, one-time rice milling, wetting, drying, two-time rice milling, polishing and color sorting and grading. The processing technology of the good-quality rice has the advantages that in each step, rice is cooled before the rice is about to be subjected to a mechanical effect; compared with traditional airing and direct one-time high-temperature drying for the rice, through a process of drying the rice, the effect of removing moisture in the rice is relieved, and heating is even; in combination with wetting and drying processes, through two-time rice milling, compared with a traditional technology, the wetting step and drying step after wetting are added, the rice milling rate is greatly reduced, and for the rice, processed through the method, in the same batch, the rice milling rate reaches 8% or below.

Description

technical field [0001] The invention relates to a processing technology of high-quality rice. Background technique [0002] Rice is one of the most commonly eaten staple foods. In a broad sense, rice processing refers to the comprehensive processing process from rice shelling to polished rice products. The rice processing process basically includes impurity removal, rice milling, polishing, color sorting, grading and packaging. [0003] In the actual production process, the broken rice rate in the rice obtained by the rice processing technology accounts for 15-30%. Due to the following two reasons, the broken rice rate will increase: The first is the various treatments before the rice processing, including the rice The state at the time of harvesting, during threshing, drying, loading and unloading transportation, etc., the paddy is crushed by mechanical impact; the second is the technological performance of rice processing machinery and equipment and the operation and man...
