Rice is one of the main food crops for the Chinese people, accounting for about a quarter of the cultivation area of food crops. Its taste is sweet and its properties are peaceful. It has various effects, such as tonifying the middle and nourishing qi, strengthening the spleen and stomach, nourishing essence and strengthening consciousness, harmonizing the five organs, promoting blood circulation, brightening the ears and eyes, relieving restlessness, quenching thirst, and stopping diarrhea. Therefore, rice is known as the "head of the five grains".
The rice we often eat has a bright color and full grains, which is because it has been carefully processed. However, ordinary rice often contains many poor qualities, such as black headed rice, moldy rice, broken rice, broken rice, belly white rice, and colored particles such as stones. These poor quality rice, if consumed by people, can pose certain risks to their health. Therefore, color selection of rice is very important. The rice color sorter can help us select high-quality rice, making our lives healthier.
The aflatoxin in rice poses a huge threat, especially during the rainy season when rice is harvested. Due to the lack of sufficient drying space, farmers usually harvest rice in advance and store it before it is fully dried. However, rice is constantly undergoing respiration, releasing the energy stored in organic matter. Some of the energy is dissipated in the form of heat, causing a large amount of heat to be generated in the newly harvested seeds. However, because they are stacked together, the heat cannot be dissipated. In addition, they often encounter typhoons and heavy rain, and cannot be spread out and dried in time, which may cause rice to sprout, mold, and rot.
The rice crushed from the sprouted and moldy rice may produce "Aspergillus flavus". The Aspergillus flavus in the moldy rice cannot be washed away, and it cannot be removed even after high temperature boiling. Experts point out that although the one-time toxicity of consuming moldy rice is not very high, long-term consumption will undoubtedly cause cancer!
Color sorting machines are created to solve such problems. There are a large number of color sorting machine manufacturers on the market, and the quality of color sorting equipment varies. Therefore, choosing a high-quality rice color sorting machine has become particularly important! How to choose a suitable color sorter for oneself?
1. Yield;
Output refers to the amount of raw materials that can be processed per hour. When selecting a model, not only should the production capacity requirements be considered, but also a margin of 10% -15% should be left to ensure the normal color selection effect. The factors that affect the output include the identification technology, structure, specifications, and model of the color sorter. In addition, the output is closely related to the type of raw materials. The proportion of residue and its specified accuracy selection are also closely related to the output.
2. Color selection accuracy;
Color selection accuracy refers to the ratio of the selected gray black residue pot to the total yield of gray black residue in wheat.
3. Selection rate;
The selection rate refers to the ratio of the number of choices made during the entire color selection process to the flow rate.
4. Comparison;
Ratio refers to the ratio of the number of residues I selected during the entire process of secondary color selection to the total number of normal wheat. The proportion is a key indicator value, generally between 1% -3%.
