principle of falling film evaporator
This equipment belongs to liquid film concentration equipment, which has high heat transfer rate and short heating time. It applies to chemical, liquid medicine, juice, and dairy production.
The theory is that the feed liquid is added in the middle of the evaporation chamber. Under the action of vacuum and gravity, the accelerating pressure head of the liquid is smaller than that of the rising film type, and the boiling point is also smaller. The temperature difference between the electric heating and the feed liquid is large, so the heat transfer effect is better.The steam enters the evaporative separation chamber for separation. The secondary steam is discharged from the top of the chamber and the concentrate is extracted from the bottom.
falling film evaporator basics
This product is widely used in the concentration of chemical, ketchup, glucose, starch sugar, oligosaccharide, caramel, sorbitol, fresh milk, fruit juice, vitamin C, maltodextrin, pharmaceutical and other aqueous solutions. Besides, it is also widely used in the waste liquid treatment of monosodium glutamate, alcohol, fish powder and other fields.
The equipment is continuously operated under vacuum and low temperature conditions, with high evaporation capacity, energy saving and consumption reduction, low operating cost, and it can maintain the original color, aroma, taste and ingredients of the processed materials to the maximum extent. It is widely used in many industries such as food, medicine, food deep processing, beverage, light industry, environmental protection, chemical industry and other fields.
The evaporator can be designed into different process flow according to the characteristics of different materials to be processed, and can also be equipped with automatic control system according to the requirements of different users.
