Key Features:

Key Feature 1 — Fully Enclosed Structure for Cleaner Processing

The sealed housing reduces external contamination risk, helps contain dust and vapors, and supports cleaner production in hygiene-sensitive plants.

Key Feature 2 — Flat-Plate Base with Low Vibration

The rigid flat-plate base and optimized drive arrangement provide smooth running, low vibration and easy installation without complicated foundations.

Key Feature 3 — Flexible Filtration and Cake Washing

The cloth-lined basket supports both filtration and in-basket cake washing. Filter cloth, pore size and basket configuration can be selected according to product characteristics.

Key Feature 4 — Broad Material Adaptability

The PSB Series performs well with high-temperature, high-viscosity, small-particle and fibrous suspensions, making it suitable for many difficult separation duties.

Key Feature 5 — Easy Access and Maintainability

The top-opening cover gives direct access to the basket and internal surfaces, simplifying inspection, filter-cloth replacement and manual cleaning between batches.

Process Characteristics (Technical Analysis):

(1) Containment and Hygiene Control

The fully enclosed design helps reduce product exposure and environmental contamination. For plants producing sensitive intermediates or high-purity products, this structure improves process cleanliness and operator protection.

(2) Suitable for Difficult-to-Filter Suspensions

The basket and feed arrangement are suitable for suspensions with fine particles, higher viscosity or fiber content, where stable cake formation and controlled liquid discharge are important.

(3) Gentle Cake Formation

The cloth-lined basket helps solids build up gradually into a uniform cake, which can reduce crystal breakage compared with harsher discharge designs and support more controlled washing and dewatering.

(4) Flexible Batch Operation

Manual top discharge allows operators to handle different products, cake thicknesses and cleaning standards more flexibly, which is valuable for multi-product workshops, trial production or specialty batches.

(5) Adaptable for GMP-Oriented Plants

With suitable surface finish, sealing arrangement and optional CIP / safety configurations, the PSB Series can be adapted for cleaner production environments and customer-specific documentation requirements.

Typical industries and products:

Pharmaceuticals & Intermediates
APIs, vitamin intermediates, amino-acid derivatives, fermentation products, excipients and other products requiring controlled washing and residual-moisture reduction.
Fine Chemicals
Dyes, pigments, catalysts, resins, borates, phosphates, silicates and other inorganic or organic intermediates requiring stable batch filtration.
Food & Functional Ingredients
Organic acids, sweeteners, starch derivatives, preservatives, food additives and other products where hygienic design and low contamination risk are important.
Electronic & Specialty Materials
Electronic chemicals, specialty powders and selected functional materials requiring clean handling and controlled impurity carry-over.
New Energy & Specialty Salt Products
Lithium-related salts, conductive additives, high-purity inorganic salts and other products where washing efficiency and solids recovery are important.

Working Principle:

The suspension is introduced from the top into the rotating basket lined with filter cloth. Under centrifugal force, the liquid phase passes through the cloth and perforated basket wall and is discharged as filtrate, while the solids are retained inside the basket and gradually form a uniform cake. When washing is required, wash liquid is sprayed onto the cake to displace mother liquor and dissolve impurities. A further spin stage reduces residual moisture. After the basket is decelerated and brought to a complete stop, the cover is opened and the operator manually loosens and removes the cake. The basket is then inspected and cleaned as required before the next batch.
