Project Description:
Protein is a necessary nutrient for the human body, accounting for 45% of the total dry matter and 70% of the total muscle mass. The main components of human cells, tissues, and organs are all proteins. Metabolism, disease resistance and immunity, fluid balance, and genetic information transmission are all closely related to proteins. Without protein, there would be no life, so protein is also known as the "nutrient" or "life element" of humans. Soy protein: refers to the protein contained in soybean products, with a content of about 38%, which is 4-5 times that of cereal foods. The amino acid composition of soy protein is similar to that of milk protein, except for slightly lower levels of arginine. The content of other essential amino acids is relatively rich, and it is a complete plant-based protein. In terms of nutritional value, it can be equivalent to animal protein. The human trial results of FAO/WHO (1985) showed that the essential amino acid composition of soy protein is more suitable for human needs. For people over two years old, the physiological potency of soy protein is 100. Soybeans are rich in protein, with a protein content almost twice that of meat, eggs, and fish. Moreover, the protein contained in soybeans has sufficient content of essential amino acids for the human body and complete components, making it a "high-quality protein". The human body's demand for protein varies depending on age, gender, weight, occupation, and other factors. In order to guide people's diets, countries around the world have developed "Recommended Daily Nutrient Allowances" (RDAs) based on their own actual situations. In 1999, the US Food and Drug Administration (FDA) issued a statement stating that consuming 25 grams of soy protein per day can reduce the risk of cardiovascular and cerebrovascular diseases. The food that modern people need should not only stimulate appetite, but also have no adverse side effects and be rich in nutrients. Among the existing food groups, soybean is the most abundant crop with the above conditions and abundant sources of raw materials. Beverages made from soy protein are praised by nutritionists as "green milk". Soy protein has a significant lowering effect on people with high cholesterol. The content of arginine in soy protein drinks is higher than that in milk, and the ratio of arginine to lysine is also reasonable; Among them, lipids and linoleic acid are extremely rich without cholesterol, which can prevent the occurrence of cardiovascular diseases in adulthood. Rich lecithin can remove excess sterols from the blood, earning it the nickname of "vascular scavenger". Soy protein drinks are easier to digest and absorb than milk. Milk tends to form large and hard lumps when it enters the stomach, while soy milk forms small thin sheets when it enters the stomach, which are soft but not hard, making it easier to digest and absorb.

Equipment Description:

On the basis of excellent process technology and rich production practice experience, the company has constantly carried out reform and innovation and designed a soybean protein spray dryer, which meets the user's requirement of producing high-quality soybean protein.


The company carries out engineering design according to the actual needs of users. At present, the soybean protein spray tower designed for Nantong Photosynthesis has a diameter of 10 meters, a height of 28 meters, and a water evaporation capacity of 5 tons per hour. It has been successfully operated. The soybean protein spray dryer is a drying device that uses the atomizer to disperse the materials into mist, fully contacts with hot air to complete instant drying, and forms powder finished products. The air first passes through the primary and intermediate filters, is heated by the heater, and then enters the air distributor at the top of the dryer. The hot air enters the drying chamber in a spiral shape and flows in parallel with the hot air. It can be dried into finished products in a very short time. The finished product is continuously output from the bottom of the high-efficiency cyclone separator, and the exhaust gas is discharged by the induced draft fan.
Equipment features:
(1) The drying speed is very fast. After spray, the surface area of the feed liquid increases. In the high-temperature airflow, most of the water can be evaporated instantly. The drying time is generally about 5-40s.
(2) The temperature of the droplets during the drying process is not high, resulting in good product quality. Temperature range for spray drying. Even if high-temperature hot air is used, the exhaust temperature will not be very high. In the early stage of drying, the material temperature will not exceed the wet bulb temperature of the surrounding hot air, which is particularly suitable for heat sensitive materials.
