With the growth of the economy, baby-related business is experiencing a period of prosperity. One of the essential products for babies is instant nutrition porridge, which is an important source of nutrition and supplement for babies. The delicate nature of a baby's stomach and intestines means that many mothers choose easy-to-digest and nutritious paste foods.

The production line for nutrition powder uses twin-screw expansion technology and can produce solutions from 100kg/h to 2-3T/h. In China, the main raw material used in nutritional powder is rice flour, while in other countries, particularly African countries, soybean flour is often added to provide a protein supplement. This production line can provide a variety of nutritious food for babies and young children. With the twin-screw expansion technology, the production process is more efficient and the final product is more nutritious and easy to digest, which is beneficial for the health and growth of babies.

Nutrition Powder Process Line

The nutrition powder baby rice food machine process involves several steps:

  1. Mixing: The raw materials, including rice flour and any other ingredients, are mixed evenly in a mixer. Water can be added during this step or directly injected into the barrel of the extruder.

  2. Twin-screw Extrusion: The evenly mixed raw materials are fed into the twin-screw extruder through a screw conveyor or other conveying equipment (varies according to production line capacity). The mixture of water and powder forms a "paste" in the barrel. The paste material is then fed, sheared, and cooked at an adjustable and controlled speed through the screw, and passes through a mold at the end. The pressure in the barrel is usually 3-6Mpa (depending on puffing requirements), and the temperature can reach 150-200 ℃. The high pressure in the closed barrel exceeds the saturated vapor pressure at the extrusion temperature, so the water does not evaporate quickly. When the material is extruded from the mold hole, the pressure is released rapidly, the free water evaporates rapidly, the material expands, and water is lost rapidly from the material. The product is then cooled to about 80 ℃ and solidified.


  3. Drying: The extruded products are dried to remove extra water and ensure the shelf time of the final product. The heating methods of the dryer can be electricity, gas, diesel, or steam, and customers can select based on local conditions.

  4. Grinding: The dried expanded particles are ground into different mesh sizes, with a mesh range of 20-120 mesh. The nutritional powder is usually 60-80 mesh.

  5. Secondary Mixing: According to market positioning and product requirements, different fruit powders, vegetable powders, and meat powders can be mixed to meet the baby's different months of age and nutritional needs.

  6. Packaging: The final product is packaged using a screw metering packing machine, which is accurate in metering, and can pack independent small packages or family-shared bags.
