Top Discharge Basket Centrifuge for Pilot-Scale Solid-Liquid Separation

The Top Discharge Basket Centrifuge is designed for pilot-scale batch filtration, cake washing, and dewatering of filterable crystal slurries, reaction precipitates, and intermediate products.

It is suitable for process development teams, pilot plants, research centers, and small-scale production lines that need to verify separation performance before selecting larger commercial equipment. The open top-discharge design allows operators to inspect the cake directly, collect samples, adjust operating conditions, and compare different filtration or washing methods between batches.

It is intended for pilot and scale-up work where process flexibility, test visibility, and practical operating data are more important than fully automatic cake discharge.

• Pilot crystallization solid-liquid separation
• Reaction precipitate dewatering trials
• Fine chemical intermediate filtration tests
• Organic and inorganic salt crystal dewatering
• Mother liquor removal studies
• Cake washing optimization
• Filter medium evaluation
• Small-batch product recovery
• Pilot drying feed preparation
• Process scale-up validation
• Multi-product campaign trials
• Batch separation before commercial equipment selection

1. Batch Feeding
   Pilot slurry enters the rotating basket lined with a suitable filter medium.
2. Liquid Filtration
   Mother liquor, solvent, or process liquid passes through the filter medium and is collected through the filtrate outlet.
3. Cake Formation
   Solids remain inside the basket and gradually form a filter cake.
4. Optional Cake Washing
   Wash liquid can be introduced to displace residual mother liquor, soluble impurities, or process residues.
5. Spin Drying
   The basket continues rotating to reduce residual liquid in the cake.
6. Machine Stop
   After the programmed cycle is completed, the basket stops safely.
7. Top Cover Opening
   The cover is opened to allow direct access to the cake.
8. Manual Cake Collection
   Operators remove the dewatered solids for sampling, drying, analysis, packaging, or further testing.

Practical Scale-Up Data

The centrifuge provides operating data closer to production conditions than small benchtop tests. This supports more reliable selection of larger separation equipment.

Direct Cake Inspection

Operators can inspect cake thickness, crystal shape, moisture condition, wash result, and filtration behavior immediately after each batch.

Flexible Test Conditions

Feed quantity, basket loading, filtration time, washing sequence, spin speed, and cycle time can be adjusted between pilot batches.

Suitable for Multi-Product Trials

The open top-discharge design allows easier cleaning, filter media replacement, and material changeover for different pilot products.

Cost-Effective Pilot Operation

The Top Discharge Basket Centrifuge provides a practical pilot solution where full automatic discharge is not required and manual product collection is acceptable.

To recommend a suitable pilot-scale centrifuge configuration, please provide:

• Material name and process stage
• Expected pilot batch volume
• Particle or crystal size distribution
• Slurry solids concentration
• Liquid composition and viscosity
• Feed temperature
• Required filtrate clarity
• Target cake moisture
• Cake washing requirement
• Product recovery target
• Filter media preference, if known
• Cleaning requirement
• Corrosion condition
• Explosion-proof requirement, if applicable
• Future commercial production capacity

Is this centrifuge suitable for laboratory work?

It is more suitable for pilot-scale and process-development batches than for very small benchtop laboratory work. It helps generate data closer to industrial operating conditions.

Can different filter media be tested?

Yes. Filter cloth, metal screen, perforated basket design, and micron rating can be adjusted according to the material’s filtration behavior.

Can the centrifuge be used to evaluate cake washing?

Yes. Wash liquid type, volume, flow rate, and cycle sequence can be adjusted to compare impurity removal, product recovery, and wash-liquid consumption.

Can pilot results support larger equipment selection?

Yes. Pilot results can help determine cake permeability, filtration time, cycle duration, target moisture, washing requirement, and suitable discharge method for production equipment.

Is manual discharge suitable for scale-up testing?

Yes. Manual top discharge provides direct cake access, making it easier to inspect material condition and evaluate product handling before selecting an automated production centrifuge.
