[Process Flow] Raw Material Cleaning Impurities - Moisture Adjustment (Wheat Watering or Washing) - Moisturizing Wheat - Grinding and Screening - Grading - Packaging and Storage
1. Raw materials: Wheat is composed of three parts: wheat embryo, endosperm, and wheat husk. The percentage of each part by weight is: endosperm 82-85%, embryo 2-3%, wheat bran 12-14%. Endosperm contains a large amount of starch and some gluten composed of protein, which is the main raw material used to make various foods such as bread and pastries. Wheat bran contains abundant dietary fiber, which is an essential nutrient element for the human body.
2. Cleaning up impurities: mainly cleaning up impurities such as straw, sand, stones, damaged wheat, fuzz, and wild grass seeds in wheat that affect the flour yield. Usually, a combination of air screening is used to remove them, and the process adopts multiple steps such as three screening, two beating, two stone removal, one wheat washing, and two magnetic separation.
3. Moisture regulation: Due to the varying moisture content and physical characteristics of different varieties and regions of wheat, some are dry and hard, while others are wet and soft. After cleaning, moisture adjustment must be carried out to achieve the optimal moisture content. The purpose of water regulation is to make wheat absorb a certain amount of water, and the protein and starch in the endosperm are displaced due to different water absorption rates, making the endosperm loose and easy to crush Make the epidermis absorb water and become tough, so that it is not easily broken during grinding to avoid affecting the powder quality Stabilize the manufacturing process.
4. Moisturizing wheat: (Storing wheat that has been soaked or washed for a period of time is called moistening wheat) Storing wheat that has been soaked for a period of time is mainly to allow water to penetrate into the wheat grains, while also making the water between the grains uniform, making it easy to separate the wheat grain skin from the endosperm, and making it easy to grind. The increased toughness of the wheat skin prevents it from breaking and affecting the flour quality, thus providing conditions for the good and stable processing of the entire process and the compliance of the finished product's moisture standards. Due to different weather and geographical conditions, the wheat variety varies, and its soaking time is generally 8-24 hours. The optimal moisture content for ground wheat is 14-16%. The soaking time and moisture content of hard wheat are generally higher than those of soft wheat.
5. Grinding and powder making: light grinding and fine grinding, skin core separation grinding. Powder making adopts 4-5 skin grinding, 6-7 core grinding, 2-3 slag grinding, and is equipped with auxiliary equipment such as powder cleaning machine, bran grinding machine, impact loosening machine, etc. It needs to be ground step by step, sieved step by step, and circulated back and forth.
6. Grading: It can be divided into 65% special flour, 75% special flour, 80% standard flour, 5-15% secondary flour, and 20% bran; Equipment with a scale of 100-150 tons can produce grade powder, specialized powder, and precision standard co production.
7. Packaging and storage: Automatic packaging, can pack 5 kilograms, 10 kilograms, 25 kilograms, and 50 kilograms according to your needs. Flour is best packaged in breathable bags for easy storage.
