Description

A defatted protein powder processing system for albumen powder production

Technical Field

The invention belongs to the technical field of food processing, and particularly relates to a defatted protein powder processing system for protein powder production.

Background

Protein is one of seven essential nutrients essential to human body, is the most important nutrient for ensuring health of human body, is necessary for maintaining and repairing body and cell growth, and not only affects growth of body tissues such as muscle, but also participates in various aspects of hormone production, maintenance of immune function, transport of other nutrients and oxygen, generation of hemoglobin, blood coagulation and the like. The human body takes in animal protein and vegetable protein through daily animal food and vegetable food, and the traditional method of supplementing protein by eating meat often takes in excessive fat, causes body fat increase and even influences the cardiovascular health. Children in their growth and development stage need a large amount of protein to meet the needs of physical development, pregnant women need a large amount of protein to produce development of red blood cells and fetuses, and the traditional big fish meat supplementation method often allows many women to have a loose stool after they have born the children because they are supplemented with a large amount of fat at the same time as proteins. Patients after surgery and in the early stage of the disease also need a large amount of protein to promote the body to recover and improve the immunity. In addition, people with poor appetite or poor digestion function, people who lose weight by a diet method and people who have vegetarians may not ingest enough protein, which not only can lead to the growth retardation of children and influence the water metabolism of the body, but also can lead to various diseases such as low immune function, poor sleep, anemia and the like. Under the conditions, the edible defatted protein powder can meet the requirement of human body on protein intake, and can avoid excessive fat intake to increase body fat.

Meanwhile, the spray drying link exists in the production process of the protein powder, and the protein powder solution is atomized and sprayed in a drying tower with high air inlet temperature, so that hot air takes away the water in the solution, and the dry protein powder is produced.
