The Critical Separation Stage in Food & Dairy Processing
In food and dairy crystallization, crystallizers only form lactose, MSG, citric acid, xylitol, edible salt, etc. — separation is the centrifuge’s job, the downstream core for closed-loop discharge, product recovery, and fermentation/whey reuse. Crystals split from saturated liquor; wet crystal advances, mother liquor returns to the crystallizer — closing the loop.
Why Separation
Performance Matters？
In food and dairy production, the centrifuge does more than “separate the crystals” — it also affects purity, whiteness, moisture, microbiology, drying energy, crystallizer scaling, and wastewater recovery value.
High Moisture
Wet residue raises downstream disposal or resource-recovery cost.
Fine Slag Loss
Fine slag lost with salt liquor reduces solids recovery and contaminates the salt solution.
Chloride Corrosion
High chloride causes pitting corrosion — shortening equipment life.
AlN Hydrolysis
AlN hydrolyzes in water, releasing ammonia — oxygen monitoring or nitrogen purge needed.
One Process. Two Separation Solutions.
For varying slurry concentrations and process swings in food and dairy, two continuous solutions: LWL and LWLZ.
LWL
Centrifugal Filtration
Screen Separation
Screw Differential Conveying
LWL: conventional solids-bearing slurry, high throughput,
continuous washing — food and dairy crystallization.
Which one
fits your
process?
LWLZ
Sedimentation Thickening
Screen Filtration
LWLZ: dilute slurry, low solids, wide feed swings, fines-heavy.
LWL Horizontal Screen Scroll Centrifuge
Continuous enclosed filtration for 24/7 food-dairy slurry — full-speed feed, wash, and discharge with no shutdown, fully sealed to cut contamination risk.
Corrosion-resistant Materials
Main parts—bowl, screw, etc. can be made of corrosion-resistant stainless steel or titanium alloy.
Filtration Screen
Dedicated filtration screen, 0.5mm thick—longer service life.
Adjustable Differential
Bowl speed is steplessly adjustable; screw differential speed adjustable in steps or steplessly.
Circulating Lubrication
Simple, reliable circulating lubrication — with pressure regulation, oil filtration, and water cooling.
Safety Protection
Speed, over-vibration, motor overload / overheat, and zero-differential protection.
LWL Series
LWLZ Horizontal Screen Decanter Centrifuge
LWLZ: settling + filtration in one — front thickening, rear screen, full-speed feed to discharge.
For low, swinging feed solids.
Gravity Discharge
Gravity discharge — minimal crystal breakage.
Deliquoring
Longer residence and deliquoring time — lower discharge moisture.
Fine Particles
Suited to fine-particle ammonium sulfate slurry.
Bowl Cone Angle
Bowl cone angle optimized at 25° for gravity-slide discharge.
Screen Slotting
Optimized screen slots improve fine-crystal retention.
LWLZ Series
LWL or LWLZ?
How to choose the right centrifuge for your battery materials?
| Comparison Criteria | LWL | LWLZ |
|---|---|---|
| Discharge Method | Screw-push Discharge | Gravity Discharge (screw-assisted distribution) |
| Suitable Particle Size | Medium Particles | Fine Particles |
| Throughput | High Throughput | Slightly Lower Than LWL At The Same Spec |
| Discharge Moisture | Relatively Low | Lower |
| Particle Breakage | Minimal | Even Less |
| Typical Applications | High-capacity Continuous Production | Fine particles, Low Moisture Requirement |
