ZDG Vibrating Fluid Dryer for Food Ingredient Processing: Citric Acid Crystals
ZDG Vibrating Fluid Dryer is evaluated for citric acid crystals in food ingredient processing. The defined feed is centrifuged citric acid crystals of the specified hydrate form. Match this duty to the material checks below and the unchanged original equipment parameters.
Citric Acid Crystals: Application and Process Requirements
For citric acid crystals, preserve hydrate identity while avoiding sticky bed deposits. Begin with centrifuged citric acid crystals of the specified hydrate form and confirm how the incoming grade varies before defining the drying cycle.
Feed, Product Quality and Downstream Handling
| Review item | Citric Acid Crystals |
|---|---|
| Defined feed | centrifuged citric acid crystals of the specified hydrate form |
| Material-specific focus | preserve hydrate identity while avoiding sticky bed deposits |
| Product checks | moisture, assay, hydrate form and crystal size |
| Downstream handling | controlled cooling before food-additive storage |
Material Movement and Drying Control
Include moisture, assay, hydrate form and crystal size in the trial record. Fix the sampling locations and analytical methods before comparing trials; feed preparation and cooling can affect the measured result.
Drying Endpoint and Product Acceptance
After acceptance, arrange controlled cooling before food-additive storage. Review discharge, temporary holding and packaging exposure as part of the moisture-control plan.
Application-Specific Equipment Selection
ZDG Vibrating Fluid Dryer selection for citric acid crystals starts with Vibrating Fluid Bed Dryer requirements and the defined feed. Assess vibratory fluidized bed dryer and fluid bed drying together with granule drying; the continuous fluidized bed dryer duty must be demonstrated using representative material and the required finished-product specification.
