It is possible to produce amounts of 50 g to 2 kg in many different processes.

A special pressure/vacuum control, this means that automatic charging and evacuation.
The powder inside the container begins to fluidise and gets moistened by an integrated three-component spray nozzle. High flexibility by top spray and bottom spray. The integrated filters are holding back the powder particles, which are led back into the process by a permanent cleanoff of the filters. Due to the moistening of the particle surfaces and its simultaneous drying, the powder particles stick together and form free-flowing agglomerates.

It is also possible to dry wet products (production by wet granulation) in the apparatus. Besides, the coating of powders and/or granules is possible, too.

The mobile system consists of 3 principal parts: The processor, the air conditioning and the control unit.

The processor consists of the air intake part, a material container with spray nozzles and specific fluidised bottom, a exhaust air part with pneumatically cleaned filters made of stainless steel or synthetic material.

The air conditioning part contains an air filter, a heat exchanger for warming up the air, a vacuum equipment and the exhaust air safety filter.

The control unit features a SPS-control with display and contains all the electric safety installations, controls and displays of all parameters which are relevant for the process.


WFP-8
Fluidbed laboratory unit

Technical unit to develop formulations

Sample amounts from 100 g to 5 kg

Drying, Agglomeration, Coating, Spray granulation

Technical Data:

Air flow volume 220 m³/h
Process air temperature: 20-100° C
Heating capacity: 9.0 kW, 400V
Fan capacity: 1,8 kW, 400 V

The processor WFP-8 is a high-grade technical unit to develop formulations as well as to produce sample amounts in batch operations.

Warm, filtered air, which passes the fluidized bottom, is sucked in by a fan into the processor. The powder inside the container begins to fluidize and gets moistened by an integrated two-component spray nozzle. The integrated filters are holding back the powder particles, which are led back into the process by a permanent cleanoff of the filters. Due to the moistening of the particle surfaces and its simultaneous drying, the powder particles stick together and form free-flowing agglomerates.

The processor consists of the air intake part, a material container with spray nozzles and specific fluidized bottom, a exhaust air part with pneumatically cleaned filters made of stainless steel or synthetic material.

The air conditioning part contains an air filter, a heat exchanger for warming up the air, a frequency controlled fan and the exhaust air safety filter.

The control unit features a SPS-control with display and contains all the electric safety installations, controls and displays of all parameters which are relevant for the process.
