The Unite MFCD series three-in-one filtration, washing, and dryingmachine is a new generation of solid-liquid separation processequipment developed from existing filtration equipment. It allows thematerial to complete the three process steps of filtration, washing, anddrying in a single enclosed vessel, maximizing equipment utilization. Itavoidsenvironmentalpollutionandpreventsenvironmentalcontamination of the material, reduces material transfer losses, andsaves on solvent usage. It is suitable for intermittent batch production.
The side discharge valve uses a metal-to-metal hard seal or an FEPsealing ring soft seal;
To ensure the sealing performance of the side discharge valve, it is equipped with an automatic or manual sealing surface cleaning device;
Two, three, or four mixing impellers can be installed to improve mixing and drying efficiency and discharge speed;
It can be used in combination with airflow drying to improve drying efficiency;
Quick-opening automatic locking device or C-ring bolt secures the main flange;
The filter medium is a multi-layer sintered metal mesh, single-layer metal or non-metallic filter cloth;
Double-end face or non-contact mechanical seals are suitable for chemical or sterile processes; Complete CIP and SIP system;
Manual or fully automatic residual material discharge device;
Complies with CGMP and FDA standards.
Each Unite three-in-one filter consists of four main parts: the vessel, thestirring mechanism assembly, the base plate, and the side discharge port.The largest part of the three-in-one filter is the vessel, with a frame formounting the stirring mechanism assembly at the top. The stirringmechanism is sealed to the equipment by a mechanical seal, and avertical shaft connects to horizontal blades installed at the bottom. Thestirring mechanism is driven by a motor and can rotate in either direction.
Furthermore, the stirring mechanism can be raised and loweredvertically by a hydraulic cylinder. The stirring action serves to smooth thefilter cake, resuspend the slurry, and discharge the filter cake. The baseplate supports the screen and filter plate. The side discharge uses asealed plunger port, which can be operated manually or automatically.
The three-in-one filter, washer, and dryer uses external pressure duringthe filtration process to force the solid-liquid mixture downwardsthrough the filter plate.
The solid phase is intercepted on the filter plate,forming a filter cake layer, achieving higher precision and better filtrationresults.
The thick cake accumulating in the filter may crack, affectingfiltration. A motor-driven rotating agitator continuously smooths thefilter cake and maintains its even distribution, while a hydraulicallydriven actuator moves the agitator vertically to follow the cake buildup.
After the filtration process is complete, the filter cake can be washed andrepulped using the agitator to achieve higher cake purity. Thethree-in-one system offers the flexibility of vacuum and/or hot air dryingto achieve the correct filter cake consistency. After the filter cake is dried,the side discharge valve opens. The agitator rotates in reverse, pushingthe filter cake out through the open discharge valve.

A Filter-Wash-Dry System is an integrated process equipment that performs solid-liquid separation, cake washing, and drying in a single closed vessel. It is widely used in industries requiring high purity and controlled processing conditions.
The system first filters slurry to form a solid cake, then washes the cake to remove impurities, and finally dries it using vacuum, inert gas, or thermal methods—all within the same unit without transferring materials.
Key advantages include fully enclosed operation, reduced contamination risk, lower material loss, improved product purity, reduced handling steps, and significant savings in labor and equipment footprint.
These systems are widely used in pharmaceuticals, fine chemicals, biotechnology, new energy materials (such as lithium battery production), and high-value chemical processing where purity and efficiency are critical.
Traditional processes require separate equipment for filtration, washing, and drying, increasing transfer loss and contamination risk. The integrated system combines all steps in one unit, improving efficiency and product consistency.
Integrated, fully automated filtration and drying solutions ensure aclosed-loop, zero-leakage production environment for high-purity chemicalprocessing
