Rice is a finished product made of rice after being cleaned, milled, milled, and finished products. The embryo and paste layer of rice contains nearly 64% of rice nutrition and more than 90% of the nutrients required by the human body, and about 50% of people in China and even the world eat rice as the main food. However, during rice processing, when the cortex and endosperm are removed, most of the nutrients in the rice are also lost. For many years, the need for fortified rice has been emphasized. Trace element deficiencies are a major cause of malnutrition and numerous chronic diseases in the population. People living in poor and remote areas are suffering from serious nutritional problems. Nutritionally fortified rice has a huge market demand.
Shandong Arrow Machinery Co., Ltd. adopts twin screw extrusion process to produce nutrient-fortified rice with crushed rice as raw material, with an output of 100kg/h-1000kg/h. The production process is: crushing – mixing – quenching and tempering – extrusion molding – drying – screening – mixing or packaging.Advantages of the twin-screw extrusion process include:
1. Crushed rice as raw material, low production cost
2. Vitamins, minerals, proteins, etc. can be added during the mixing process to increase nutritional value
3. The high temperature time of the extrusion process is short, the nutritional components in the food are almost not destroyed, and the extrusion process changes the structure and properties inside the molecule, so that some of them are converted β starch into α starch, which is convenient for the human body to absorb;
4. Flexible raw materials, in addition to rice, corn, sorghum, oats, buckwheat, barley, barley, mung beans, red beans and other coarse grains can be added to improve the single food structure.
5. Twin screws are available in conventional LT series and high-end FT series, flexible drying scheme, adapting to customer needs of different outputs and standards.
