Food-Grade Crystal Dewatering Bag Lifting Centrifuge
The hygienic bag lifting centrifuge is designed for batch dewatering of food-grade crystalline materials.
It is suitable for food-grade crystals that require clean operation, gentle handling, easy discharge, and reduced product loss during solid-liquid separation.
For food-grade crystal production, Peony provides not only centrifuge equipment, but also process evaluation, model selection, filter bag matching, material configuration, and separation performance support.
Food-grade crystal dewatering requires more than simple liquid removal. The centrifuge must also protect the product quality during feeding, filtration, washing, dewatering, and discharge.
This solution is suitable for:
| Food-Grade Material | Application Purpose |
|---|---|
| Food additive crystals | Clean crystal dewatering |
| Sugar crystals | Gentle solid-liquid separation |
| Starch-based crystalline products | Batch dewatering and recovery |
| Salt-based food ingredients | Moisture reduction after washing |
| Granular food ingredients | Low-breakage dewatering |
| Small-batch food crystals | Clean batch discharge |
The bag lifting structure is especially suitable when the product needs clean discharge, low manual contact, easy cake removal, and flexible batch operation.
In food-grade crystal production, common separation problems include:
| Problem | Possible Cause | Solution Focus |
|---|---|---|
| Wet crystal cake | Fine particles, high liquid retention, short dewatering time | Basket speed, cycle time, filter bag selection |
| Crystal breakage | Excessive speed, harsh discharge, manual scraping | Gentle operation and bag lifting discharge |
| Difficult discharge | Sticky cake or compacted crystals | Proper filter bag and cake thickness control |
| Product loss | Manual handling or unsuitable discharge method | Bag lifting recovery |
| Cleaning difficulty | Poor structure access or unsuitable surface finish | Hygienic design and easy cleaning access |
| Filter bag blockage | Fine particles or wrong mesh size | Filter medium matching |

The contact parts can be made of stainless steel according to food-grade production requirements. Smooth surfaces and accessible internal structures help reduce residue and make cleaning easier.
Bag Lifting Discharge
The crystal cake can be lifted out together with the filter bag. This reduces manual scraping, improves discharge cleanliness, and helps reduce product loss.
Gentle Crystal Handling
The bag lifting discharge method is more suitable for food-grade crystals that should not be heavily broken or damaged during unloading.
Custom Filter Bag Selection
Filter bag material and mesh size can be selected according to crystal size, filtration speed, liquid clarity, and product recovery requirements.
Easy Cleaning and Batch Changeover
The open basket and removable filter bag design make cleaning and batch changeover more convenient, especially for food-grade production lines.
Stable Batch Dewatering
The centrifuge supports stable batch operation for food-grade crystal production where moisture control and clean discharge are required.
Available Custom Options
The centrifuge can be customized according to the process:
| Item | Available Configuration |
|---|---|
| Contact material | SS304 or SS316L |
| Basket size | Selected according to batch capacity |
| Filter bag | Selected according to particle size and filtration requirement |
| Surface treatment | Polishing available for cleaner operation |
| Discharge method | Bag lifting discharge |
| Control system | Standard or customized control |
| Cleaning access | Designed according to food-grade cleaning needs |
| Lifting method | Matched with site layout and discharge height |
To recommend the right hygienic bag lifting centrifuge, please provide:

Downstream process: drying / packaging / further refining
Is this centrifuge suitable for food-grade crystal dewatering?
Yes. It is designed for batch solid-liquid separation of food-grade crystalline materials requiring clean discharge and controlled dewatering.
Why use a bag lifting centrifuge instead of manual discharge?
Bag lifting discharge reduces manual scraping, makes cake removal easier, and helps reduce product loss during discharge.
Can it reduce crystal breakage?
Yes, the bag lifting discharge method is gentler than heavy manual scraping. The final breakage rate also depends on crystal strength, basket speed, and operating time.
Can the filter bag be customized?
Yes. The filter bag can be selected according to crystal size, filtration speed, liquid clarity, and product recovery requirements.
What information is needed before selection?
Material name, particle size, solids content, batch capacity, liquid property, target moisture, and cleaning requirements should be confirmed before model selection.
