Top Discharge Centrifuge for Organic Salt Crystallization Separation

The Top Discharge Basket Centrifuge is designed for batch separation of organic salt crystals after crystallization, neutralization, concentration, or purification.

It is suitable for filterable organic salt slurry where the crystals need to be separated from mother liquor, optionally washed, spin dried, and manually removed through the top opening. Typical materials may include citrate salts, lactate salts, acetate salts, gluconate salts, amino acid salts, and other organic salt crystals with stable cake-forming behavior.

Compared with fully automatic discharge centrifuges, the top discharge design provides a simpler structure and more direct access to the basket. This is useful for small and medium batches, pilot production, multiproduct plants, and processes where operators need to inspect the crystal cake before discharge.

• Organic salt crystal separation after crystallization
• Citrate salt crystal dewatering
• Lactate salt crystallization separation
• Acetate salt crystal recovery
• Gluconate salt dewatering
• Amino acid salt crystal separation
• Food additive organic salt processing
• Fine chemical organic salt purification
• Mother liquor removal after salt crystallization
• Crystal cake washing before drying
• Small-batch organic salt production
• Pilot and multiproduct crystallization lines

Peony provides batch separation solutions for the process section between organic salt crystallization and downstream drying, screening, or packaging.

A typical process arrangement is:

Crystallizer / Neutralization Reactor → Slurry Holding Tank → Top Discharge Basket Centrifuge → Mother Liquor Collection or Recycle → Optional Cake Washing → Spin Drying → Manual Top Discharge → Dryer / Screen / Packaging

The centrifuge separates mother liquor from the organic salt crystals before drying. Where product purity is important, a controlled washing step can be added to displace residual mother liquor, soluble impurities, color bodies, or residual reactants from the crystal cake.

The manual top discharge design also allows operators to inspect crystal size, cake thickness, washing result, and residual liquid before the material is transferred to downstream equipment.

Peony Solution Scope

Peony supports customers with:

• Basket size and batch-capacity selection

• Corrosion and solvent compatibility review
• Integration with crystallizers, dryers, screens, and packaging systems
• Installation guidance, commissioning, spare parts, and operator training

1. Slurry Feeding
   Organic salt crystal slurry enters the rotating basket lined with filter media.
2. Mother Liquor Filtration
   Mother liquor passes through the filter medium and is collected through the filtrate outlet.
3. Crystal Cake Formation
   Organic salt crystals are retained inside the basket and gradually form a filter cake.
4. Optional Cake Washing
   Compatible wash liquid can be introduced to reduce residual mother liquor, soluble impurities, color bodies, or reaction residues.
5. Spin Drying
   The basket continues rotating to reduce free liquid retained in the crystal cake.
6. Machine Stop and Cover Opening
   After the programmed cycle is completed, the basket stops and the top cover is opened.
7. Manual Top Discharge
   Operators remove the dewatered organic salt cake from the basket and transfer it to downstream drying, screening, milling, or packaging equipment.

Flexible for Small and Medium Crystal Batches

The top discharge design is suitable for batch crystallization processes where production volumes, crystal properties, or product grades may change between campaigns.

Direct Cake Inspection Before Discharge

Operators can inspect the crystal cake after the cycle is completed. This is useful for checking crystal condition, cake thickness, wash performance, and residual liquid before downstream drying.

Controlled Mother Liquor Removal

Centrifugal filtration removes mother liquor from the organic salt crystal bed before drying. This helps reduce carryover of dissolved impurities and lowers the downstream drying load.

Optional Washing for Product Purity

A controlled wash step can reduce residual mother liquor, soluble salts, color bodies, or process residues trapped between crystals. Wash conditions should be selected according to the solubility and stability of the organic salt.

Easier Changeover for Multi-Product Processes

The accessible top-opening structure supports cleaning, filter media replacement, and product changeover. This is useful for organic salt production lines that process different grades or multiple product types.

To recommend a suitable Top Discharge Basket Centrifuge, please provide:

• Organic salt name and intended product grade

• Feed temperature
• Required batch capacity
• Target cake moisture
• Cake washing requirement
• Product purity requirement
• Manual discharge acceptability
• Corrosion condition
• Required material of construction
• Downstream drying and packaging arrangement
• Explosion-proof requirement, if applicable

Is a Top Discharge Basket Centrifuge suitable for organic salt crystallization?

Yes. It is suitable for filterable organic salt crystals that can form a stable cake and require batch filtration, optional washing, spin drying, and manual discharge.

Can the centrifuge reduce residual mother liquor on the crystals?

Yes. Filtration and centrifugal spin drying remove free mother liquor from the crystal cake. A controlled wash step can further reduce liquid retained between the crystals.

Can organic salt crystals be washed inside the basket?

Yes. An optional washing system can be installed. The wash liquid type, quantity, and cycle time should be selected according to the solubility and purity requirement of the organic salt.

Why use top discharge for organic salt batches?

Top discharge provides direct access to the basket after the cycle. This allows operators to inspect the cake, verify washing performance, and remove the product manually, which is useful for flexible or multiproduct batch production.

Can this centrifuge be used before vacuum drying?

Yes. The dewatered organic salt cake can be transferred to vacuum dryers, tray dryers, conical dryers, fluid-bed dryers, or other downstream drying equipment.
