Hygienic-Design Pusher Centrifuge for Lysine Dewatering

Hygienic -Design Pusher Centrifuge for Lysine Crystal Dewatering is designed for continuousdewatering, mother liquor separation, and optional cake washing of lysine crystals in amino acid,fermentation, feed additive, and food ingredient production lines.

Lysine products are often produced through fermentation, concentration, crystallization, and dryingprocesses. After crystallization, the slurry may contain lysine crystals, mother liquor, solubleorganics, residual salts, fine crystals, and process liquid.

A pusher centrifuge removes free liquidthrough centrifugal filtration and continuously discharges dewatered lysine crystal cake beforedrying, cooling, screening,or packaging.

• Lysine crystal dewatering
• L-lysine crystal solid-liquid separation
• L-lysine HCI crystal dewatering
• Lysine mother liquor separation
• Lysine crystal cake washing and dewatering
• Wet lysine cake discharge before drying
• Amino acid crystallization product dewatering
• Fermentation-derived crystal product handling
• Feed-grade lysine crystal processing
• Continuous lysine drying and packaging line integration

The actual separation result depends on lysine product type, crystal size, slurry concentration,mother liquor composition, liquid viscosity, screen opening, washing requirement, and hygienerequirements.

Lysine is commonly used as a feed additive, food ingredient, or amino acid product. Compared with mineral salts or inorganic chemicals, lysine crystal handling requires more attention to product cleanliness, residual mother liquor, organic residue, and downstream drying stability.

If the dewatering stage is not properly controlled, the plant may face:

• High moisture in wet lysine cake
• Higher drying energy consumption
• Residual mother liquor on crystal surfaces
• Higher organic carryover into the final product
• Product caking during drying or storage
• Unstable feeding to dryer or cooler
• Fine crystal loss through unsuitable screen openings
• Crystal build-up or screen blockage
• More frequent cleaning due to organic residue
• Product quality fluctuation before packaging

A hygienic-design pusher centrifuge helps separate mother liquor from lysine crystals continuously, while optional cake washing can reduce residual soluble impurities.

Lysine crystal slurry enters the centrifuge through the feed pipe and is evenly distributed onto the rotating screen basket.

Under centrifugal force, mother liquor passes through the screen openings and is collected as filtrate. Lysine crystals are retained on the screen surface and form a filter cake.

The pusher mechanism moves the lysine crystal cake forward step by step. During this movement, the cake continues to lose free liquid.

If product washing is required, wash liquid can be sprayed onto the cake to reduce residual mother liquor, soluble organics, or surface impurities.

Finally, the washed and dewatered lysine crystal cake is discharged continuously from the basket end and sent to the dryer, cooler, screening machine, packaging section, or next process stage.

Under suitable feed and operating conditions, the system can typically help achieve:

• 5–12% wet cake moisture for many well-formed lysine crystals
• 50–80% reduction in free mother liquor carryover before drying compared with untreated wet slurry.
• 90–98% retention of target-size lysine crystals when the screen opening is properly matched with particle size distribution.
• 30–60% reduction of residual soluble mother liquor when cake washing is properly applied.
• 15–35% reduction in downstream dryer inlet liquid load
• More stable wet cake 
• Better control of organic residue carryover and product cleanliness before drying.
• 8–24 hours/day continuous operation

Final performance depends on lysine product type, crystal size distribution, slurry concentration, mother liquor composition, viscosity, screen opening, washing ratio, temperature, and operating parameters.
