Pharmaceutical and Nutraceutical Drying Solutions
Drying Solutions for Extracts, Powders, Granules and Intermediates
Changhai provides spray, vacuum, fluid-bed, hot-air and related processing equipment for traditional Chinese medicine extracts, plant extracts, powders, granules and selected pharmaceutical-related or health-product materials.
Selection is based on feed state, heat sensitivity, viscosity, moisture target, batch or continuous duty, collection requirement, cleaning method and downstream processing.
Extract and Granule Drying Challenges
Heat Sensitivity
Heat-sensitive extracts and intermediates require the drying temperature and residence time to be established for the material.
Viscosity & Deposition
High-viscosity or sugar-containing extracts may deposit on the drying chamber and require a suitable feed, atomization, wall-protection and collection arrangement.
Powders & Environment
Powders and wet granules require suitable air distribution, agitation or tray loading to achieve the required drying duty and practical discharge. Product-contact material, cleaning access, dust collection and changeover requirements must be defined for the intended production environment.
Recommended Equipment for Extracts and Granules
ZLPG Series Spray Dryer for TCM Extract
For high-viscosity or heat-sensitive extract feeds requiring spray drying and anti-sticking measures.
LPG Series Centrifugal Spray Dryer
For general pumpable solutions, emulsions and suspensions requiring powder production.
YZG/FZG Static Vacuum Dryer
For tray-loaded, small-batch, multi-product and heat-sensitive materials.
SZG, ZPG and LDG Vacuum Dryers
For suitable powders, granules, pastes, slurries and extracts requiring batch vacuum drying.
GFG and FG Fluid-Bed Dryers
For wet granules and powders requiring batch fluid-bed drying.
CT/CT-C Hot-Air Circulation Oven
For tray-loaded materials that can be dried with circulating hot air.
FL, FLP, GHL and related equipment
For projects that also require granulation, coating or mixing operations.
Equipment Selection by Feed Form
Use ZLPG for traditional Chinese medicine or similar extract feeds where high viscosity, heat sensitivity and wall deposition must be considered.
Use LPG for general pumpable liquid feeds suitable for centrifugal spray drying.
Use vacuum dryers for tray-loaded, powder, granular, paste or slurry materials requiring reduced-pressure batch drying.
Use GFG or FG for wet granules and powders suitable for batch fluid-bed drying.
Use CT/CT-C ovens for tray-loaded materials suitable for circulating hot-air drying.
Any GMP, validation, containment or cleanroom requirement must be specified separately and confirmed for the project.
Pharmaceutical-Related and Health-Product Applications
The documented equipment range is relevant to traditional Chinese medicine extracts, plant extracts, amino acids, vitamins, selected pharmaceutical intermediates, powders, wet granules and other process materials.
The applicable dryer depends on whether the feed is liquid, paste-like, tray-loaded, powder or granule form.
Material and Process Data
For liquid extracts, provide viscosity, solids content, feed rate, evaporation duty, thermal sensitivity and target powder properties.
For powders, granules or pastes, provide initial and target moisture, batch size, flowability, stickiness, temperature limit, product-contact requirements, cleaning method and discharge condition.
Drying and Collection System Configuration
Spray-drying systems combine feed preparation, atomization, filtered hot air, drying, powder separation, collection and exhaust treatment.
Vacuum-drying systems combine a sealed dryer, indirect heating, vacuum generation, vapor piping and optional condensation or recovery equipment.
Fluid-bed systems combine filtered and heated air, air distribution, drying, product collection and exhaust treatment.
Contact materials, cleaning access, feeding, discharge, control functions and plant layout are defined for the selected equipment.
Material Evaluation and Equipment Support
Changhai has a sample-testing center and pilot workshop and specializes in the drying of traditional Chinese medicine extracts, biological products, polysaccharide foods, food additives, chemical raw materials and moisture-sensitive pastes.
Support can include material discussion, representative testing where applicable, equipment selection, drawing confirmation, manufacturing, inspection, factory testing, installation guidance and after-sales communication.
High-Viscosity Plant Extract Spray Drying
Typical Project Scenario
A plant-extract producer needs to convert a high-viscosity, heat-sensitive liquid extract into powder and is concerned about wall deposition, powder recovery and stable collection.
For this duty, Changhai can configure a ZLPG extract spray-drying system with liquid feeding, centrifugal atomization, filtered hot air, a drying chamber, cyclone separation, powder collection and dust control. Anti-sticking and wall-cooling measures are selected for the extract.
The system atomizes the extract into fine droplets for rapid moisture evaporation, while the anti-sticking and collection arrangement addresses wall deposition and powder recovery. Final feed concentration, temperatures and equipment size are confirmed from the material data or testing.
From Material Review to Equipment Delivery
The project begins with feed form, composition, viscosity or particle data, moisture target, temperature limit, capacity, cleaning method and site conditions.
The workflow can include material evaluation, dryer selection, drawing confirmation, manufacturing, inspection or factory testing, shipment, installation guidance and after-sales support.
Pharmaceutical-Related Drying FAQ
Which spray dryer suits a high-viscosity extract?
ZLPG is designed for traditional Chinese medicine extracts and similar high-viscosity or heat-sensitive feeds requiring anti-sticking and specialized collection arrangements.
Which dryer suits tray-loaded materials?
YZG/FZG static vacuum dryers or CT/CT-C hot-air circulation ovens may be considered according to temperature and pressure requirements.
Can sticky materials be processed?
Sticky materials require review of viscosity, solids or sugar content, feeding, agitation or atomization, wall deposition, cleaning and discharge.
Can the equipment be used for pharmaceutical-related production?
Equipment can be configured for selected extracts, powders, granules and intermediates. Any GMP, validation, containment or cleanroom requirement must be specified and confirmed separately.
What information is required?
Provide the material/form, viscosity or particle data, moisture target, temperature limit, batch or feed rate, contact-material requirement, cleaning method and collection requirement.
