Embodiment 1

[0048] Such as figure 1 Shown, a kind of paddy processing polishing process, described concrete steps are as follows:

[0049] (1) Finishing before rice polishing: pick out the rice with more broken pieces, select the rice with less broken pieces and pour them into the polishing machine;

[0050] (2), polishing in the wet polishing machine: the rice is polished in the polishing chamber by means of water;

[0051] (3) Grading management after polishing: divide the rice into first, second and third grades;

[0052] (4) Finished product: pack the first-grade, second-grade and third-grade paddy separately.

[0053] In step (2), the wet polishing machine uses water to spray atomized water at high pressure: that is, an air compressor is used to generate atomized water, so that a thin water film is formed on the surface of the rice.

[0054] Step (2) When the wet polishing machine is polishing, the pressure of the polishing chamber is 50Mpa, and the pressure of the polishing chamb...

Embodiment 2

[0060] Such as figure 1 Shown, a kind of paddy processing polishing process, described concrete steps are as follows:

[0061] (1) Finishing before rice polishing: pick out the rice with more broken pieces, select the rice with less broken pieces and pour them into the polishing machine;

[0062] (2), polishing in the wet polishing machine: the rice is polished in the polishing chamber by means of water;

[0063] (3) Grading management after polishing: divide the rice into first, second and third grades;

[0064] (4) Finished product: pack the first-grade, second-grade and third-grade paddy separately.

[0065] In step (2), the wet polishing machine uses water to spray atomized water at high pressure: that is, an air compressor is used to generate atomized water, so that a thin water film is formed on the surface of the rice.

[0066] Step (2) When the wet polishing machine is polishing, the pressure of the polishing chamber is 40Mpa, and the pressure of the polishing chamb...

Embodiment 3

[0072] Such as figure 1 Shown, a kind of paddy processing polishing process, described concrete steps are as follows:

[0073] (1) Finishing before rice polishing: pick out the rice with more broken pieces, select the rice with less broken pieces and pour them into the polishing machine;

[0074] (2), polishing in the wet polishing machine: the rice is polished in the polishing chamber by means of water;

[0075] (3) Grading management after polishing: divide the rice into first, second and third grades;

[0076] (4) Finished product: pack the first-grade, second-grade and third-grade paddy separately.

[0077] In step (2), the wet polishing machine uses water to spray atomized water at high pressure: that is, an air compressor is used to generate atomized water, so that a thin water film is formed on the surface of the rice.

[0078] Step (2) When the wet polishing machine is polishing, the pressure of the polishing chamber is 60Mpa, and the pressure of the polishing chamb...

Abstract

The invention discloses a rice processing and polishing process which comprises the following specific steps: sorting out before rice polishing: picking out rice containing more broken rice, and selecting and pouring rice containing less broken rice in a polishing machine; polishing in the wet polishing machine: polishing the rice in a polishing chamber with the help of water; performing grading management after polishing: dividing the rice into the primary, the secondary and the tertiary rice; obtaining a finished product: respectively packaging the primary, the secondary and the tertiary rice, wherein the rate of the broken rice contained in the rice is more than or equal to 50 percent, which shows that the more broken rice is contained; the rate of the broken rice contained the rice isless than 50 percent, which shows that the less broken rice is contained. The rice processing and polishing process disclosed by the invention has the benefits that the gelatinization of starch on thesurface of the rice is facilitated through proper water temperature, and then gullies on the surface of the rice can be flatly filled or smoothly polished through mutual friction in the polishing process, so that the glossiness of the rice is increased; the rice can be extruded by applying a proper pressure in the polishing chamber to be conducive to the polishing of the rice.

Description

technical field [0001] The invention relates to the technical field of paddy processing, in particular to a paddy processing and polishing process. Background technique [0002] Paddy refers to the fruit without removing the rice husk, which belongs to the common rice subspecies in the common cultivated Oryza subgenus of the genus Poaceae Oryza botany. A total of 22 types of rice have been identified by humans, but the only one used for bulk trade is the common type of rice. my country is one of the countries with the longest history of rice cultivation and the richest rice genetic resources. Carbonized rice unearthed in Hemudu, Zhejiang, Luojiajiao, Hunan, and Jiahu, Henan proves that rice cultivation in China has a history of at least 7,000 years. One of the origins of cultivated rice in the world. [0003] Polishing is one of the key processes in cleaning rice processing. Since polishing can remove the bran powder on the surface of rice, proper polishing can gelatinize t...
