The Bag Lifting Centrifuge is designed for batch recovery, washing, and dewatering of delicate, high-value, or easily damaged filterable crystals.
Some crystals can be affected by aggressive manual scraping, excessive handling, uneven feeding, strong wash flow, or repeated transfer between equipment. In these cases, the separation target is not only to remove mother liquor. The process must also maintain crystal integrity, reduce product residue, and support cleaner collection after each batch.
This discharge method helps reduce direct scraping from the basket wall and can lower unnecessary handling during product collection. It is suitable for small- to medium-batch duties where product value, crystal appearance, particle integrity, or cleaner batch transfer are important.
Peony provides the batch solid-liquid separation section between crystallization and downstream drying, screening, storage, or packaging.
Crystallizer / Slurry Tank → Controlled Feeding → Bag Lifting Centrifuge → Mother Liquor Collection → Optional Cake Washing → Spin Drying → Filter Bag Lifting → Dryer / Screen / Storage / Packaging
Peony can provide:
Crystal slurry enters the rotating basket lined with a suitable filter bag. Feed rate is controlled to support even loading and reduce excessive crystal movement.
Mother liquor or process liquid passes through the filter bag and basket perforations before leaving through the filtrate outlet.
The retained crystals remain inside the filter bag while the liquid phase is discharged.
As feeding continues, the crystals form a stable filter cake inside the bag. Cake thickness is controlled according to crystal condition and required cycle time.
Compatible wash liquid can be introduced to reduce residual mother liquor, soluble impurities, or color-bearing liquor retained between crystals.
For soluble or fragile products, wash flow, wash volume, and wash sequence should be selected carefully to limit unnecessary crystal dissolution or mechanical disturbance.
The basket continues rotating to reduce free liquid retained in the crystal cake before discharge.
After the programmed separation cycle is complete, the centrifuge stops and the top cover is opened.
The filter bag containing the dewatered crystal cake is lifted out and transferred to a collection bin, dryer feed station, screen, storage bin, or packaging process.

The crystal cake remains inside the removable filter bag during discharge. This reduces the need for direct scraping from the basket wall and supports more controlled product collection.
Manual scraping can disturb fragile, large, or high-value crystals. Whole-bag lifting helps reduce direct contact between tools and the retained cake.
Feed rate, washing sequence, spin time, and discharge timing can be adjusted according to crystal strength, particle size, cake thickness, and target moisture.
The lifted bag can be moved directly to a collection bin, dryer feed station, or downstream handling point. This can reduce unnecessary transfer steps and product loss between separation and drying.
For products where material loss, crystal damage, or residual hold-up has a direct impact on production value, contained bag discharge provides a more controlled collection method.
| Component | Typical Options |
|---|---|
| Product-contact material | SS304 or SS316L, as required |
| Filter bag material | Synthetic fiber, food-compatible material, or customized material |
| Filter bag micron rating | Selected according to crystal size and filtrate clarity target |
| Seals and gaskets | Silicone, EPDM, PTFE, FKM, or compatible materials |
| Surface finish | Standard cleanable finish or polished product-contact finish |
| Control mode | Manual, semi-automatic, or PLC-controlled batch operation |
| Cake washing | Optional low-flow spray washing system |
| Cleaning method | Manual cleaning, spray-ball cleaning, or customized cleaning arrangement |
| Product collection | Collection trolley, bin, hopper, dryer feed connection, or customized handling point |
| Electrical configuration | Standard or explosion-proof, as required |
Please provide:
It can be suitable when the crystals are filterable and able to form a stable cake. The bag lifting arrangement helps reduce direct basket-wall scraping and supports more controlled product collection.
No. Crystal breakage depends on the material itself and the actual operating conditions, including feed rate, basket speed, cake thickness, washing method, and downstream transfer arrangement.
The whole-bag discharge method can reduce residual product inside the basket, reduce manual scraping, and simplify transfer to downstream equipment.
Yes. An optional washing system can reduce residual mother liquor or soluble impurities. Wash liquid and wash volume should be selected carefully for soluble or delicate products.
Yes. The lifted filter bag or collection bin can be connected with a vacuum dryer, tray dryer, fluid-bed dryer, screen, storage bin, or packaging system.
Peony welcomes distributor and agent cooperation with food ingredient suppliers, fine chemical producers, crystallization contractors, specialty chemical companies, organic acid processors, and batch solid-liquid separation partners.
