The Bag Lifting Centrifuge is designed for batch recovery, washing, and dewatering of citric acid crystals after crystallization.
Citric acid crystal slurry usually contains product crystals, mother liquor, residual soluble impurities, and fine particles. The separation task is not only to remove liquid. It must also protect crystal quality, reduce mother liquor carryover, limit product dissolution during washing, and collect the finished cake with low residue.
This design is suitable for food-grade, additive-grade, and high-purity citric acid crystal production where clean batch handling and low-residual product collection are important.
Peony provides the batch solid-liquid separation section between crystallization and downstream drying or packaging.
Citric Acid Crystallizer → Slurry Holding Tank → Bag Lifting Centrifuge → Mother Liquor Collection / Recycle → Optional Cake Washing → Spin Drying → Filter Bag Lifting → Dryer / Screen / Packaging
Peony can provide:
Citric acid crystal slurry enters the rotating basket lined with a suitable filter bag.
Mother liquor passes through the filter bag and is collected through the filtrate outlet.
Citric acid crystals remain inside the filter bag while the liquid phase is discharged.
The retained crystals gradually form a filter cake inside the bag.
Compatible wash liquid can be introduced to reduce residual mother liquor, soluble impurities, or color-bearing liquor retained between crystals.
The basket continues rotating to reduce free liquid retained in the crystal cake.
After the programmed separation cycle is complete, the centrifuge stops and the top cover is opened.
The filter bag containing the dewatered citric acid crystal cake is lifted out and transferred to a collection bin, dryer feed system, or downstream handling station.

The filter bag allows the product cake to be removed as a contained batch, reducing the need for manual scraping inside the basket.
The bag lifting structure supports controlled batch collection and helps reduce direct contact between product and the centrifuge shell during discharge.
A washing stage can be configured to reduce residual mother liquor and improve crystal cleanliness before drying.
The system is suitable for products where material recovery, low residual hold-up, and batch traceability are important.
The removable bag arrangement supports filter media replacement, product changeover, and cleaning between different production campaigns.
| Component | Typical Options |
|---|---|
| Product-contact material | SS304 or SS316L, as required |
| Filter bag material | Food-compatible synthetic fiber or customized material, based on product and cleaning requirement |
| 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 |
| Cleaning method | Manual cleaning, spray-ball cleaning, or customized cleaning arrangement |
| Electrical configuration | Standard or explosion-proof, as required by the plant environment |
The final filter bag and product-contact material should be confirmed based on citric acid concentration, wash liquid, operating temperature, cleaning chemicals, and food-contact requirements.
To recommend a suitable citric acid crystal recovery solution, please provide:
Yes, when the citric acid crystals can form a stable and filterable cake. It is particularly suitable for batch operation where clean collection and low-residual product handling are important.
Yes. An optional washing system can be configured. However, wash conditions must be controlled carefully because citric acid is soluble and excessive washing may reduce product recovery.
The filter bag helps contain the crystal cake during removal. It can reduce product residue in the basket and supports cleaner handling for high-value or food-grade crystal products.
Yes. The collected mother liquor can be returned to the crystallization section, routed for recovery, or sent to further treatment depending on the overall process route.
Yes. The lifted bag or collected cake can be transferred to a fluid-bed dryer, vacuum dryer, tray dryer, screen, or packaging section according to the plant layout.
Peony welcomes distributor and agent cooperation with citric acid producers, food ingredient manufacturers, organic acid processing plants, crystallization contractors, and batch solid-liquid separation partners.
We support centrifuge selection, filter bag matching, cake washing design, product-contact material selection, mother liquor recovery connection, hygienic configuration, installation guidance, commissioning support, spare parts, and after-sales service.
Send us your citric acid crystal form, batch capacity, crystal size, slurry solids concentration, mother liquor composition, target moisture, washing requirement, and downstream handling arrangement.
