AZODOS® type P … DV dosing unit is used for volumetric metering of powdered products in weighing and finishing processes. The machine can be used in the food, pharmaceuticals, chemicals and plastics industries for feeding production processes with a constant mass flow in coarse or fine flow.

By adding a weighing device, the machine can be extended to form the AZODOS® type P... DW dosing system for gravimetric feeding of processes. The machine can be used as loss-in-weight scales to dose small quantities into the downstream system with gram accuracy. The AZODOS® P… DW is used with the AZO®CONT dosing controls for feeding continuous gravimetric processes, resulting in a DDW loss-in-weight feeder.

Design of AZODOS® types P … DV and DW

The basic machine consists of a housing where, depending on the model, one or two dosing screws are installed. The dosing screws are driven by frequency-controlled gear motors. An upstream discharge agitator serves to ensure that the dosing screws are evenly filled from surge bins. The surge bins are available in a variety of models and sizes and, depending on the model, can be filled under gravity, pneumatically or manually. An extraction device can be used to remove the dosing screws from the back of the housing, which makes cleaning or replacing individual components very simple.

If the basic machine is expanded with a platform load cell or a 3-point weighing frame, this forms an AZODOS® type P … DW dosing system that can be used as loss-in-weight scales. Flexible connections at the supply hopper inlet and screw outlet decouple the system thus preventing force shunts. If the Azodos p….DW is combined with the AZO®CONT dosing controls, this creates a loss-in-weight feeder. The controls continuously regulate the mass flow in terms of target and actual throughput.


Operating principle of AZODOS® type P … DV, DW, DDW

The AZODOS® Type P … DV operates in volumetric mode. The powder bulk products flow out of the supply hopper into the dosing screw. An agitator is used to ensure uniform discharge. With a frequency-controlled motor, the dosing screw can be switched from coarse to fine flow for precision dosing in the downstream weighing process.
