into one complete drying system.
- Spray Drying Equipment
- Pressure Spray Drying Equipment
- Centrifugal Spray Drying Equipment
- Rotary Drying Equipment
- Pneumatic Drying Equipment
- Flash Drying Equipment

- Tower Circulation Drying Equipment
- Superheated Steam Drying Equipment
- Combined Drying Systems
Select Drying Equipment According to Material Properties
The first question in an industrial drying project is which drying method is suitable for the material.
During the initial project stage, the main information to confirm includes:
What material needs to be dried?
Is the feed liquid, slurry, filter cake, powder, granule or bulk material?
What is the initial moisture content?
What is the required final moisture content?
What processing capacity is required per hour or per day?
What final product form is required?
Is the material heat-sensitive?
Is it likely to stick, agglomerate or break?
What energy sources are available locally?
Based on these conditions, Meibao selects the appropriate dryer and supporting systems.
Spray Drying Equipment
Spray drying is mainly suitable for solutions, suspensions, emulsions and slurries.
The liquid feed is atomized into fine droplets and brought into contact with hot air inside the drying tower, where moisture is rapidly evaporated to form powder or granular products.
Depending on the product requirements, the system can use:
- Pressure Atomization
- Centrifugal Atomization
- Other Suitable Atomization Methods
Typical Process
For some products, spray drying can also be combined with:
for further drying, cooling or particle finishing.
Typical Applications
- AOS
- K12
- Sodium Sulfonates
- Pesticides
- Humic Acid
- Lignin
- Calcium Chloride
- Ceramic Body Powder
- Phosphate Products
- Other Chemical Liquids and Slurries
Rotary Drying Equipment
Suitable for many types of granular, crystalline, mineral, fertilizer and bulk materials.
Rotary drying is suitable for a wide range of materials and relatively large processing capacities.
Depending on the project, Meibao can configure:
- Single-Pass Rotary Dryers
- Three-Pass Rotary Dryers
- Rotary Drying + Cooling
- Rotary Drying + Screening
- Granulation + Rotary Drying
Typical Process
Typical Applications
- Potassium Chloride
- Potassium Sulfate
- Monoammonium Phosphate
- Diammonium Phosphate
- Compound Fertilizer
- Bio-Fertilizer
- Silica Sand
- Tea and Selected Agricultural Products
- Other Granular and Mineral Materials
Pneumatic, Flash and Fluidized Bed Drying Equipment
For powders, filter cakes, high-moisture materials and certain granular products, rapid drying systems can be selected according to actual material characteristics.
Pneumatic Drying
The material is dispersed, conveyed and dried in a high-velocity stream of hot air.
Suitable for selected:
- Powders
- Fine Granular Materials
- Chemical Materials
- Inorganic Materials
- Feed Additives
Flash Drying
Flash drying is suitable for certain filter cakes, paste-like materials, high-moisture powders and materials prone to agglomeration.
Typical applications include:
- Kaolin
- Desulfurization Gypsum
- Phosphogypsum
- Other Chemical and Mineral Materials
Depending on the material, a combined Pneumatic + Flash Drying process can also be configured.
Fluidized Bed Drying
A fluidized bed uses hot air to keep granular material in a fluidized state for drying or cooling.
- Granular Chemical Products
- Fertilizers
- Feed and Additives
- Selected Agricultural By-Products
A combined system can also be configured as: Spray Drying → Fluidized Bed → Screening → Finished-Product Treatment (post-treatment after spray drying).
Agricultural Product Drying Equipment
Agricultural product drying differs from chemical-material drying and may need to consider appearance, breakage, color, flavor and storage stability.
Besides reducing moisture, the system may also need to consider:
- Product Appearance
- Breakage Rate
- Color
- Flavor
- Heat Sensitivity
- Drying Uniformity
- Storage Stability
Therefore, different agricultural products require different drying methods.
Tunnel Drying Equipment
Tunnel dryers are suitable for selected agricultural products requiring relatively gentle and staged hot-air drying.
Typical applications: Longan, Coffee, Selected Fruits and Vegetables, Other Agricultural Products Suitable for Tray or Continuous Drying.
Belt Drying Equipment
Materials are continuously distributed on a mesh belt and pass through multiple hot-air drying zones.
Suitable for: Longan, Fruits and Vegetables, Selected Agricultural By-Products, Materials Requiring Continuous Drying.
Different drying zones and hot-air conditions can be configured according to product requirements.
Rotary Drying for Agricultural Products
For agricultural materials that can tolerate tumbling and movement, rotary drying can also be used.
Typical applications: Tea, Selected Granular Agricultural Products, Other Products Suitable for Rotary Drying. The equipment is designed according to product requirements for temperature and breakage control.
Tower Circulation Grain Drying Equipment
Typical products: Grain, Wheat, Corn, Soybeans.
Key considerations: Initial Grain Moisture, Target Storage Moisture, Batch or Daily Processing Capacity, Drying Temperature, Product Breakage Rate, Heat-Source Cost, Continuous or Batch Operation Requirements.
Feed and Additive Drying
Depending on the material form, pneumatic, spray, fluidized bed or other drying equipment can be used for feed products and industrial by-products.
Typical Products
- Dicalcium Phosphate
- Monocalcium Phosphate
- Distillers Grains
- Brewer's Grains
- Fermented Residues
- Other Feed and Additive Products
Equipment Selected by Material Condition
- Dicalcium Phosphate - depending on material condition, can be processed using Pneumatic Drying
- Monocalcium Phosphate - depending on production process, Spray Drying can be used
- Distillers Grains - for selected high-moisture materials, a Superheated Steam Pneumatic Drying System can be evaluated
- Brewer's Grains - depending on feed moisture and final product requirements, Fluidized Bed or Other Suitable Drying Equipment can be configured

Complete Process Summary
At the same time, Drying Exhaust → Dust Collection → Exhaust Treatment is designed as part of the complete system.
Integrated Heat-Source and Drying-System Design
Drying is often one of the major energy-consuming stages, so the heat source should be selected according to actual local energy conditions.
Available options can include:
- Natural Gas
- LNG
- LPG
- Heavy Fuel Oil
- Light Diesel
- Biomass
- Coal
- Steam
- Industrial Waste Heat
- Other Available Energy Sources
Direct-Fired or Clean Hot Air?
For applications where combustion hot air is allowed to contact the material directly, a direct-fired hot-air system can be considered. For food and agricultural products, products sensitive to odor, products with strict color requirements, or materials requiring higher hot-air cleanliness, an indirect clean hot-air system or another suitable heating method can be evaluated.
The final heat-source solution is selected according to: Material Requirements, Product Requirements, Local Energy Cost, Energy Supply Stability.
Why Should Drying Equipment Be Customized?
Even when the same type of dryer is used, the actual equipment configuration may vary significantly between different materials.
Key design factors include:
- Initial Moisture Content
- Final Moisture Content
- Processing Capacity
- Liquid Concentration
- Viscosity
- Particle Size
- Bulk Density
- Heat-Sensitive Temperature
- Wall-Sticking Characteristics
- Product Breakage Requirements
- Product Color Requirements
- Final Particle Requirements
Therefore, Meibao designs and selects drying equipment according to actual material conditions rather than simply offering fixed standard models.
