Fully Enclosed Stainless Steel Vibrating Fluidized Bed Dryer For Food Pharma

Fully Enclosed Stainless Steel Vibrating Fluidized Bed Dryer For Food Pharma

The ZLG Series Fully Enclosed Vibrating Fluidized Bed Dryer is a premium thermal processing solution specifically engineered to meet the stringent hygiene and safety standards of the Food and Pharmaceutical industries. Constructed entirely from high-grade stainless steel (SUS304/316L), this system ensures zero cross-contamination while delivering exceptional drying and cooling efficiency for sensitive granular materials.

In the food and pharma sectors, equipment cleanability and environmental integrity are non-negotiable. Our ZLG series features a fully enclosed structural design that isolates the drying process from the external atmosphere. This prevents dust leakage and protects high-purity products—such as pharmaceutical intermediates, vitamins, and food additives—from airborne contaminants.

Working Principle

Material is fed into the machine via the inlet and moves forward continuously along the horizontal fluidized bed surface under the influence of precisely tuned vibration force. Hot air is forced upward through the perforated fluid bed, making direct contact with the wet material. This process facilitates rapid heat and mass transfer. The moisture-laden air is purified through a cyclone separator before being exhausted, while the dried product is discharged through the outlet.

Engineered for Material Integrity

Traditional drying methods often lead to particle attrition or surface damage due to aggressive mechanical agitation. The ZLG series solves this by using a "throwing" motion induced by dual vibration motors. The material moves forward in a semi-suspended state, significantly reducing friction and impact, which preserves the crystal form and surface quality of the product.

Core Technical Advantages

• Total Material Protection: The vibration-induced fluidization is exceptionally gentle. It allows materials to move in a "throwing" motion without aggressive mechanical friction, preserving the integrity of fragile crystals, seeds, and granules.

• Superior Energy Efficiency: Optimized airflow dynamics and mechanical efficiency allow this system to save 30%–60% in energy costs compared to conventional drying units.

• Hygienic Mirror-Polished Finish: All internal contact surfaces are mirror-polished ($Ra < 0.4mu m$), eliminating dead corners and ensuring compliance with CIP (Clean-in-Place) protocols.

• Uniform Fluidization & Drying: The synchronized dual vibration motors ensure even material distribution across the bed, preventing "dead zones" and ensuring every particle achieves a consistent final moisture content.

• Stepless Precision Controls: Operators can perform stepless adjustment of bed thickness, residence time, and vibration amplitude to accommodate varying production requirements and material densities.
