Bag Lifting Centrifuge for Fructose Crystallization
Description
The Bag Lifting Centrifuge is designed for the solid-liquid separation, crystal washing, and dewatering of fructose crystals after crystallization.
In crystalline fructose production, the slurry contains fructose crystals and mother liquor. The centrifuge separates the crystals from the liquid phase, reduces residual mother liquor in the cake, and prepares the product for downstream drying, screening, packaging, or further refining.
The machine is installed after the crystallization stage. Its role is to recover fructose crystals efficiently while supporting hygienic batch operation and controlled product handling.
It is suitable for crystalline fructose slurry with stable cake-forming behavior, food-grade handling requirements, and a need to reduce product loss during discharge.
Typical Fructose Crystal Applications
- Crystalline fructose production
- Food-grade fructose crystal separation
- Refined fructose crystal dewatering
- Fructose mother liquor separation
- Fructose crystal washing before drying
- Fructose recovery after batch crystallization
- Starch-based sweetener processing
- Food ingredient manufacturing
- High-purity fructose production
- Fructose crystal recovery before screening and packaging
Why Choose a Bag Lifting Centrifuge for Fructose Crystal Separation?
Fructose crystal separation requires controlled mother liquor removal, hygienic product handling, and reduced crystal loss during discharge.
Typical operating challenges include:
- Residual mother liquor affecting product purity
- High product value and low loss tolerance
- Hygroscopic product behavior during handling
- Crystal dissolution risk during washing
- Variable crystal size after crystallization
- Requirement for controlled cake moisture before drying
- Hygienic production requirements
- Need for complete batch recovery
- Need to reduce manual scraping inside the basket
- Requirement for stable and repeatable washing performance
The Bag Lifting Centrifuge addresses these requirements through centrifugal filtration, controlled cake washing, high-speed spin drying, and top bag-lifting discharge.

How the Bag Lifting Centrifuge Works in Fructose Crystallization
The fructose crystal slurry enters the rotating basket lined with a filter bag and supporting filter screen.
Under centrifugal force:
- Mother liquor passes through the filter bag and is collected through the filtrate outlet.
- Fructose crystals are retained inside the basket.
- A crystal cake gradually forms on the inner surface of the filter bag.
- Optional wash liquid is introduced to reduce residual mother liquor and improve crystal purity.
- High-speed rotation removes residual moisture from the fructose crystal cake.
- The machine stops after the programmed cycle is completed.
- The filter bag containing the dewatered crystal cake is lifted through the top discharge section.
- The fructose crystals are collected or transferred to downstream drying, screening, packaging, or further processing equipment.
The complete batch cycle can be controlled through PLC operation to maintain stable filtration, repeatable washing performance, and consistent product handling.

Main Advantages in Fructose Crystal Separation
Efficient Mother Liquor Removal
The centrifuge separates mother liquor from fructose crystals effectively, reducing liquid carryover into downstream drying and packaging systems.
Controlled Cake Washing
An optional wash system can reduce residual mother liquor and improve crystal purity before final spin drying.
For fructose applications, the washing medium and wash quantity should be selected carefully to avoid unnecessary crystal dissolution or product loss.
Bag-Lifting Product Discharge
The lifting mechanism raises the filter bag containing the crystal cake, helping improve batch recovery and reduce manual scraping inside the basket.
Hygienic Product Handling
The equipment can be configured with food-grade contact materials, hygienic seals, polished surfaces, and CIP cleaning options.
Lower Cake Moisture
High-speed centrifugal dewatering helps reduce residual moisture before drying, screening, or packaging.
Reduced Product Loss
The bag-lifting discharge arrangement supports controlled crystal collection and helps reduce product retention inside the machine.
Stable Batch Operation
PLC-controlled operation can manage feeding, filtration, washing, spin drying, bag lifting, and safety interlocks in a repeatable sequence.
Hygienic Design and Material Selection
For fructose processing, product-contact components should be selected according to food-grade hygiene requirements and cleaning conditions.
