The top discharge basket centrifuge is designed for batch solid-liquid separation and dewatering of dye intermediate crystals.
It is suitable for dye intermediate production lines that require flexible batch operation, reliable crystal recovery, controlled cake moisture, easy cleaning, and anti-corrosion configuration.
For dye intermediate crystal dewatering, Peony provides not only centrifuge equipment, but also material evaluation, model selection, filter cloth matching, washing process support, anti-corrosion material selection, and separation performance support.
Dye intermediate crystal dewatering is a key step after crystallization, reaction, washing, or precipitation. The separation result directly affects product purity, drying efficiency, mother liquor recovery, and batch quality.
This solution is suitable for:
| Material Type | Application Purpose |
|---|---|
| Dye intermediate crystals | Mother liquor separation and crystal dewatering |
| Pigment intermediate crystals | Batch solid-liquid separation before drying |
| Organic chemical crystals | Moisture reduction after crystallization |
| Fine chemical intermediates | Crystal recovery and cake washing |
| Colored crystalline products | Controlled filtration and easy cleaning |
| Small-batch chemical crystals | Flexible batch dewatering |
| Solvent-containing crystal slurry | Enclosed or anti-corrosion configuration after evaluation |
| Acidic or alkaline mother liquor systems | Material selection and corrosion protection |
The top discharge basket structure is especially suitable for dye intermediate projects with multi-product production, frequent batch changeover, medium batch capacity, and cost-sensitive investment requirements.
In dye intermediate production, common separation problems include:
| Challenge | Possible Cause | Solution Focus |
|---|---|---|
| High cake moisture | Fine crystals, poor permeability, short spin time | Basket speed, dewatering time, cake thickness |
| Slow filtration | Small particle size or viscous mother liquor | Filter cloth matching and feeding control |
| Color residue | Colored mother liquor or poor cleaning access | Easy-cleaning structure and batch cleaning |
| Product contamination | Residue from previous batch | Surface finish, cleaning method, filter cloth replacement |
| Crystal loss | Wrong filter cloth mesh or unstable cake formation | Filter medium selection and cake control |
| Corrosion risk | Acid, alkali, chloride, solvent, or high temperature | SS316L, duplex steel, titanium, or lining options |
| Difficult discharge | Sticky cake or compacted crystals | Proper loading volume and manual discharge tools |
| Unstable batch quality | Feed concentration or particle size changes | Process evaluation before model selection |
| System Part | Function |
|---|---|
| Slurry feeding system | Feeds dye intermediate crystal slurry into the basket |
| Top discharge basket centrifuge | Separates mother liquor and dewaters crystal cake |
| Filter cloth / filter bag | Retains crystals and controls filtrate clarity |
| Cake washing system | Removes residual mother liquor or impurities |
| Mother liquor outlet | Collects filtrate for recovery or treatment |
| Manual top discharge | Allows visible cake condition and flexible unloading |
| Cleaning access | Supports batch changeover and color residue cleaning |
| Anti-corrosion configuration | Matches acidic, alkaline, solvent, or chloride conditions |
| Downstream connection | Dryer, tray, collection bin, or packaging process |
The typical process is:
Filter Cloth Installation → Slurry Feeding → Basket Filtration → Crystal Cake Formation → Optional Cake Washing → Final Dewatering → Top Manual Discharge → Crystal Collection → Cleaning for Next Batch
During operation, the dye intermediate slurry enters the basket. Under centrifugal force, the liquid phase passes through the filter cloth and basket perforations. The solid crystals are retained and form a cake on the basket wall. After optional washing and final dewatering, the operator discharges the crystal cake from the top.
This process is suitable for dye intermediate crystals that require flexible operation, visible cake condition, controlled washing, and easy cleaning between batches.

Dye intermediate plants often handle different products in small or medium batches. The top discharge basket centrifuge allows flexible operation and easier batch adjustment.
Operators can directly observe the cake condition from the top, which helps when the crystal size, color, viscosity, or filtration behavior changes between batches.
Compared with fully automatic discharge centrifuges, the top discharge basket centrifuge has a simpler structure and lower investment cost. It is suitable for batch production and cost-sensitive projects.
The centrifuge can be equipped with a washing pipe to support cake washing, mother liquor replacement, and product purity improvement.
The open-top structure makes internal cleaning, filter cloth replacement, and residue inspection more convenient, especially for colored dye intermediate materials.
Contact parts can be selected according to the process liquid, including SS304, SS316L, duplex stainless steel, titanium, or lining structure.
| Item | Available Configuration |
|---|---|
| Contact material | SS304, SS316L, duplex steel, titanium, lining options |
| Basket size | Selected according to batch capacity |
| Filter cloth | Selected according to crystal size and filtrate clarity |
| Washing system | Optional cake washing pipe |
| Motor | Standard or explosion-proof motor |
| Sealing design | Open, semi-closed, or sealed design |
| Surface treatment | Polishing or anti-corrosion treatment |
| Control system | Standard control or customized control cabinet |
| Cleaning design | Easy cleaning access, cleaning port, or removable filter cloth |
| Discharge tool | Manual scraper, shovel, or customized discharge tool |
