Types and Selection of Mother Liquor Drying Machines
1、 Common types of mother liquor drying machines
Spray Dryer
Principle: The mother liquor is atomized into small droplets, which are then brought into contact with hot air (or inert gas) in a drying tower in a forward, backward, or mixed flow manner. The moisture evaporates instantly, resulting in powdered or granular dry materials.
Characteristics:
Very suitable for processing mother liquor with low viscosity and good fluidity.
Continuous operation, large processing capacity.
The product is a uniform powder or particle with good fluidity.
The thermal efficiency is relatively high (depending on the hot air temperature and exhaust gas recovery).
The equipment has a large volume and a high tower body. The nozzle or centrifugal atomizer is a critical component.
There are certain requirements for the feed concentration (usually not too thick).
Exhaust gas treatment (including dust and solvent vapor) is the key and difficult point.
