Bag Lifting Centrifuge for Glucose Crystallization

The Bag Lifting Centrifuge is designed for the solid-liquid separation, crystal washing, and dewatering of glucose crystals after crystallization.

The equipment is suitable for batch glucose crystallization processes where hygienic handling, controlled cake washing, reduced residual moisture, and complete product recovery are required.

It is commonly used for crystalline glucose, dextrose monohydrate, food-grade glucose products, and other sugar crystal separation 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

Glucose crystal separation requires controlled mother liquor removal, hygienic product handling, and reduced product loss during discharge.

Typical operating challenges include:

• Residual mother liquor affecting crystal purity
• Hygroscopic crystal behavior during handling
• Crystal dissolution risk during washing
• Variable crystal size after crystallization
• Requirement for lower moisture before drying
• Need for hygienic batch operation
• Product retention inside the basket
• Need for complete batch recovery

The Bag Lifting Centrifuge addresses these requirements through centrifugal filtration, optional cake washing, controlled spin drying, and top bag-lifting discharge.

Peony provides centrifuge equipment and separation support for glucose crystallization, starch sugar processing, food ingredient production, and hygienic crystal recovery projects.

Process Evaluation

Our engineers evaluate:

• Crystal size and cake-forming behavior
• Slurry solids content and mother liquor properties
• Target moisture and product purity
• Cake washing requirement
• Required batch capacity and downstream drying conditions

Equipment Selection

We help customers select:

• Suitable basket size and filter bag specification
• Filter screen and feed configuration
• Cake washing and spin-drying arrangement
• Bag lifting discharge system
• Product-contact materials, CIP option, and PLC automation level

The glucose crystal slurry enters the rotating basket lined with a filter bag and supporting filter screen.

Under centrifugal force:

1. Mother liquor passes through the filter bag and is collected through the filtrate outlet.
2. Glucose crystals are retained inside the basket.
3. A crystal cake gradually forms on the inner surface of the filter bag.
4. Optional wash liquid is introduced to reduce residual mother liquor and improve crystal purity.
5. High-speed rotation removes residual moisture from the glucose crystal cake.
6. The machine stops after the programmed cycle is completed.
7. The filter bag containing the dewatered crystal cake is lifted through the top discharge section.
8. The glucose 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.

For glucose processing, product-contact components should be selected according to food-grade hygiene requirements and cleaning conditions.

To recommend a suitable Bag Lifting Centrifuge, please provide:

• Glucose product grade

• Target cake moisture
• Product purity requirement
• Cake washing requirement
• Downstream drying method
• Product-contact material requirement
• Surface finish and CIP requirement
• Installation area
• Power supply
• Explosion-proof requirement, if applicable
