Problems solved by technology

However, in the prior art, the rice processing process is long, the processing cycle is long, the energy consumption is large, and the efficiency is low, which makes the rice and the machine have a long contact cycle, which greatly affects the taste and quality of the processed rice.

Embodiment 1

[0025] Rice processing method, comprises the following steps:

[0026] (1) The rice harvested from the paddy field is dried by hot air through the hot air dryer, and in this process, the sundries are removed. After the rice is dry, it is lifted into the rice storage bin by the hoist, and the rice storage bin is controlled. Store rice at a temperature of 25-33°C, and use an exhaust fan to extract the humidity in the rice storage bin, so that the humidity at the bottom of the rice storage bin is maintained at 8-15%;

[0027] (2) The rice is released from the bottom of the storage bin so that the time for each kilogram of rice to pass through the bottom of the storage bin is 30-40s, continuously released from the bottom of the storage bin, and sent to the huller through the conveyor belt to remove the husk and remove the husk rate of 85-90%, to obtain brown rice;

[0028] (3) The brown rice is transported to the paddy separator through a pipeline with an internal humidity of 40-...

Embodiment 2

[0031] On the basis of Example 1, the operation mode in step (4) is to send the complete grain of rice into the freezer, control the temperature to be 3-6°C, and the humidity to be 15-20%, after refrigerating for 1-3min, send into Polishing is carried out in a polishing machine, and the broken rice is screened out by a sieving machine, and then color sorting is carried out by a color sorter to remove different-colored rice grains, and the finished rice is obtained.

Embodiment 3

[0033] On the basis of embodiment 1, after adopting polishing in step (4), color sorting is carried out again, realizes three throwing three color sorting modes, improves the sensory effect of the bead round jade embellish of rice, crystal clear.

Abstract

The invention relates to the technical field of rice processing, in particular to a method for processing rice. Through the control on the rice processing steps and environment parameters of rice, thebroken rice rate of the rice during unhusked rice processing to the rice is greatly improved, the steps needing to detect and control the water content in each process step is reduced, it is achievedthat the temperature and humidity of the transmission link are controlled in the process of transmission, so that cooling and the improvement of the tenacity of rice grains are achieved in the process of transmission, the fissure rate and the broken rice rate are reduced, and the integrality of the rice grains is improved.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a rice processing method. Background technique [0002] In my country, most people take rice as the staple food, which has the characteristics of delicious taste, special aromatic flavor and easy digestion, and can be accepted by the majority of consumer groups. With the continuous advancement of science and technology, rice processing methods are also constantly improving, so that traditional rice is only peeled off the chaff to improve the smoothness of rice, and then to reduce the loss of rice nutrition, reduce the rate of rice broken rice, etc., but in any case, every No processing method can be separated from frictional heat generation during rice processing. The main reason is that during rice processing, friction must occur between rice paddies, between rice paddles, and between paddy paddles and machines. The husk on the surface of the rice can be peeled off, exp...
