Description

Technical Field

[0001] This utility model belongs to the field of condensate recovery, specifically a condensate recovery device for a milk powder drying tower heater. Background Technology

[0002] A milk powder drying tower is a specialized piece of equipment used for spray drying of milk powder. It uses spray drying technology to convert liquid milk powder raw materials into powdered products. During the operation of the drying tower, the air first passes through a filter to remove impurities, then is heated to a suitable temperature by a heater, and finally the used air is discharged by a fan.

[0003] Since the drying tower achieves evaporation through evaporation, the exhaust gas contains a large amount of condensate, which contains a large amount of heat. If this heat is not utilized, it will be wasted. At the same time, the waste also contains dust-like impurities, which will settle in the surrounding environment if directly discharged, affecting environmental sanitation.
