Semi-Automatic Powder Dissolver

The Semi-Automatic Powder Dissolver (S-APD2) is designed for customers that do not need a fully automatic powder dispenser and -dissolver, but do want to dissolve powder dyes in a controlled environment.

It dissolves products following one of the customizable processes with a limited number of variables that can be set by the operator.


Hot and cold water will be dispensed into the dissolving tank through flowmeters and electro-pneumatic valves. The product to be dissolved is manually added in standardised weighing pans of 20 / 80 liters.


Tank content is 500 liters (other sizes upon request). Batch sizes range from 30 to 300 liters.

Easy operation

The PLC software on an industrial microterminal allows for an easy operation. After placing the pan inside the tank, the dissolving process takes place  automatically, no further operator intervention is required.


The unit can be integrated into an automated dyehouse, combining powder dispensing, dissolving and distribution to the dye machines.


The dissolving process operates fully automatic, there is no need for operator intervention during the process.


Each dissolving tank can be filled with a mix of hot and cold water to reach the required temperature and volume. The pneumatically operated cover can  open and close automatically. Multiple dissolving processes can be defined.


The unit is constructed in stainless steel. Heavy duty pumps and pneumatics ensure a trouble-free and long life.

Safe and Clean

The dissolving takes place inside the closed tank, avoiding possible dust or product loss. No fumes or steam can escape the tank resulting in a safe and clean working area. The cover is only opened after the batch has been transported and the dissolving tank and powder pails are clean.
