The brown rice colored granules of the tank are transferred to the stone separator 5 with the help of the control panel 12 and the conveying means 13, and then precipitated. Sized (large and small) is stored in the lip storage tank (7) → The brown rice colored lip of the colored lip storage tank (7) is transferred to the rice mill (8) and drawn by the selected particle size → to the color sorter (9) Transported to remove foreign matters and color sorting → transported to vibrating separator 10 to remove waste → transported to weighing packing machine 11, after weighing packing or tailing, transfer to processing line of weighing packing or rice grain processing (RPC) By processing, a fine grain (whole grain or nearly fine grain) reprocessed from brown rice colored granules is obtained.

That is, the brown rice colored granules generated in the brown rice milling process are collected and then precipitated with a stone separator (5) to remove stones and foreign matters, and then the size of the brown rice colored granules is large, small or large, with a vibrating separator (6). By classifying small, medium, and the same size or similar size (large, small) and then milling rice by size using the rice milling machine (8), the milling yield is improved (raised).

The colored grains coated with white rice are removed through the color sorter (9), foreign matters and bad tastes are removed, and after the waste is removed by the vibrating sorter (10), it is packed or polished with the weighing packing machine (11) and then weighed or re-injected. Through the part 16, the rice grains reprocessed from the brown rice grains are obtained by being transferred and processed to the processing line of the rice grain processing plant (RPC), thereby greatly improving the milling yield in the rice grain processing plant and waste of grain resources. Is prevented.

In the case of the brown rice colored granules, red rice, green rice, mixed grains (colored rice) and the like are reprocessed and selected to be milled and recovered.

Example 3 White Rice Wrapping Process

White rice waste (large and crushed), which is a by-product generated from the milling process of rice grains in a rice grain processing plant (RPC), is collected in the by-product collecting unit (2) and then crushed (white rice) of the by-product tank (3) by the by-product conveying unit (4). Stored in tanks and large (white rice) tanks.

The white rice waste of the tank is transported to the stone separator 5 with the help of the control panel 12 and the conveying means 13 and then precipitated and transferred to the color sorter 9 to remove foreign substances and to sort out the colors. It is transported to the sorting machine 10 and sorted according to the size of fire (large and small) → It is transported to the weighing packing machine 11 and then weighed or shredded by the size of the wrapped (large and small) ) Is obtained.

That is, the white rice waste (crushed, large chain) generated in the white rice milling process is precipitated with a stone separator (5), etc. to remove stones and foreign matters, and then transferred to a color sorter (9) to remove foreign substances and color sorting, and then to a vibration sorter. By removing the dust with (10) and sorting by the size (large and small crushing) of waste, white rice bran is obtained by weighing and packing, thereby greatly improving the milling yield in the rice grain processing plant and preventing waste of grain resources.

Example 4 White Rice Recoloring Process

White rice, which is a by-product generated in the milling process of the rice flour processing plant (RPC), is collected in the by-product collecting unit 2 and then stored in the colored lip (white rice) tank of the by-product tank 3 by the by-product conveying unit 4. .

The white rice colorant of the tank is transferred to the stone separator 5 with the help of the control panel 12 and the conveying means 13 and then precipitated and then transferred to the color sorter 9 to remove foreign substances and color picking. The waste is removed by being transferred to the sorting machine (10), and then it is transferred to the weighing packing machine (11), and then precisely sorted from white rice colored granules by transporting and processing to the processing line of the weighing package or rice grain processing plant (RPC). Complete beauty is obtained.

About 50% of the complete rice is contained in the colored rice (white rice) collected in the white rice milling process. That is, when separating the colored rice by spraying with air from the color sorter of the rice grain processing plant (RPC), about 50% of perfect rice (normal rice) is mixed in addition to the colored rice. Therefore, by completely sorting about 50% of the complete rice mixed with the white rice colorant with the color sorter 9, perfect rice is recovered from the colorant rice (white rice), thereby significantly improving the milling yield in the rice grain processing plant and increasing the grain resources. Waste is avoided.

Example 5 White Rice Flour Refining Process

White rice powder granules, which are by-products generated in the milling process of rice flour at Ryeok (R), are collected in the by-product collecting section (2) and then by the by-product conveying section (4). Are stored in.

White rice powder granules of the tank, with the help of the control panel 12 and the conveying means 13, etc. are transferred to the stone separator 5 and then precipitated and then transferred to the color sorter 9 to remove foreign substances and color separation. → the waste is removed by vibrating sorter 10 and then is transferred to weighing packaging machine 11 to be transported and processed to the processing line of weighing package or rice grain processing plant (RPC) after weighing packaging or tailing. Complete beauty to be carefully selected is obtained.

White rice powder granules collected during the milling process contain about 50% of complete rice. That is, when separating the powdered granules by spraying them with air from the color sorter of the rice grain processing plant (RPC), about 50% of perfect rice (normal rice) is mixed in addition to the powdered granules. Therefore, by thoroughly sorting about 50% of the perfect rice mixed in the white rice powder granules again with the color sorter 9, the complete rice is recovered from the white rice powder grains, thereby greatly improving the milling yield in the rice grain processing plant and the grain. Waste of resources is prevented.

In the present invention, if the grain size of the brown rice and the white rice to be reprocessed by the present invention is not classified into the same or similar size, the milling yield is greatly reduced during re-coating. Therefore, in the present invention, the sorting body (selection net) of the vibrating separator 6, 10 is composed of two stages, three stages, or four stages, but is replaced with a screen having a different pore size from the sorting body depending on the type and nature of the by-product. As a result, it is possible to freely classify (separate) fine powder, small chains, large chains and perfect rice (normal rice). In addition, the milling yield is greatly improved by classifying (separating) the grain size of brown rice and white rice into two or three stages and applying them to the same or similar size.

Table 2 below shows the by-product generation rate according to the present invention, by reprocessing and selecting in a manner consistent with the type and properties of the by-products to recover and obtain high-quality rice, greatly reduced to about 0.2% in the case of non-established , The colored granules were greatly reduced to about 0.3%, and in the case of fire (large and small chains), it was greatly reduced to about 1.5%, and the colored granules and pulverized granules were significantly reduced to about 2%, compared with the conventional by-product generation rate shown in Table 1. It can be seen that the overall by-products have been greatly reduced. Therefore, the milling yields of RPC and rice milling companies are greatly improved, leading to improved profits and minimal loss of grain resources.

division Kind (appearance) ratio Brown rice
Immature (winning) About 0.2% Colored Lip (Color Separator) 0.3% White rice
Large chain, small chain (vibration separator) About 1.5% Colored granules, powdery granules About 2%
