Problems solved by technology

[0003] At present, the traditional rice milling method has a large mechanical pressure when removing the cortex, which leads to high processing brittleness, and easily causes rice grains to break and crack, which not only affects the rice processing quality, but also has problems such as high energy consumption; After the completion, the rice grains of different sizes and the impurity particles mixed in the rice cannot be separated in time, which will increase the follow-up screening work

Embodiment 1

[0034] Embodiment 1: see figure 1 , a method for whitening rice, comprising the steps of:

[0035] (1) Atomization treatment: first use the compound enzyme liquid of cellulase, maltase and protease to infiltrate brown rice by spraying;

[0036] (2) Rice milling: the brown rice after soaking treatment in step (1) is sent in the rice milling device to carry out rice milling process;

[0037] (3) Blanking: transport the semi-polished rice after rice milling from the rice milling box to the distribution box;

[0038] (4) primary screening: large-grain rice and small-grain rice are screened out by the first filter screen;

[0039] (5) Secondary screening: small-grained rice and impurity particles are screened out through the second filter screen.

[0040] Preferably, in the compound enzyme liquid: cellulase is 50wt%, maltase is 10wt%, and protease is 8wt%.

[0041] Preferably, the temperature of the atomization treatment is 30°C, and the enzymolysis time is 0.5h.

[0042] Use ...

Embodiment 2

[0043] Embodiment 2: The same as embodiment 1 will not be repeated, and the difference with embodiment 1 is:

[0044] see Figure 2-4 , the rice milling device includes a rice milling box, the middle part of the rice milling box is rotatably equipped with rolling rollers, the top of the rice milling box is provided with several sets of first air blowers, and the left side of the rice milling box is fixedly equipped with a delivery box A transmission shaft is fixedly installed in the middle of the delivery box, the transmission shaft is fixedly connected with the rolling roller and has a concentric structure, and a helical blade is fixedly installed on the outside of the transmission shaft, and the rice in the delivery box is transported to the mill through the helical blade. Rice milling in the rice box;

[0045] The top of the left side of the delivery box is fixedly equipped with a rice feeding bucket, the inside of the delivery box is connected with the rice milling box, t...

Abstract

The invention discloses a rice whitening method. The rice whitening method comprises the following steps of (1) atomization treatment, namely soaking brown rice with a compound enzyme solution of cellulase, maltase and protease in a spraying manner; (2) rice milling, namely feeding the soaked brown rice in the step (1) into a rice milling device for rice milling; (3) discharging, namely conveyingmilled semi-polished rice from a rice milling box into a material distribution box; (4) primary screening, namely screening out large-grain rice and small-grain rice through a first filter screen; and(5) secondary screening, namely screening out the small-grain rice and impurity grains through a second filter screen. The invention relates to the technical field of rice processing. The method reduces the broken rice rate in the rice milling process, improves the rice milling quality and improves the rice processing efficiency.

Description

Technical field: [0001] The invention relates to the technical field of rice processing, in particular to a rice whitening method. Background technique: [0002] Rice is the staple food of southerners. In order to obtain high-quality rice, it needs to go through multiple steps of processing to obtain high-quality rice. Rice processing must first screen the rice, select good rice, and then perform preliminary cleaning, and remove the stones in the rice to avoid mixing stones in the rice. After husking, the husk of the rice is removed, and the husk is put into the rice husk and separated from the rice. The rice separated from the husk needs to be magnetically separated to remove metal debris and other impurities in the rice. Rough milling and finishing milling are performed on the rice from which impurities etc. have been discharged. Finally the rice is polished and finally packed. [0003] At present, the traditional rice milling method has a large mechanical pressure when...
