Used air type process dryer, also known as a direct-fired dryer or convection dryer :

An air type process dryer, also known as a direct-fired dryer or convection dryer, is a type of industrial dryer that uses heated air to remove moisture from materials. It's a versatile technology widely used across various industries for drying a broad range of products.

How it Works

In an air type process dryer, heated air is forced through a bed of material, causing the moisture within the material to evaporate. The moist air is then exhausted, leaving behind the dried product. The heat can be generated by burning fuel (natural gas, propane, oil) or by electric heaters.

Applications

Air type process dryers are used to dry a wide variety of materials, including:

• Agricultural products: Grains, seeds, hay, fruits, vegetables
• Food products: Pasta, snacks, coffee, tea
• Minerals: Sand, gravel, clay
• Chemicals: Fertilizers, polymers, powders
• Wood products: Lumber, sawdust, wood chips
• Textiles: Fabrics, yarns

Types of Air Type Process Dryers

There are several types of air type process dryers, each designed for specific applications and materials:

• Rotary dryers: These consist of a rotating drum through which heated air is passed. They are commonly used for drying bulk materials like minerals and grains.
• Fluid bed dryers: In these dryers, a bed of material is suspended by an upward flow of heated air. They are ideal for drying particulate materials like powders and granules.
• Spray dryers: These dryers are used to dry liquids by spraying them into a stream of hot air. They are commonly used in the food and pharmaceutical industries.
• Belt dryers: These dryers use a conveyor belt to transport material through a stream of heated air. They are suitable for drying sheet-like materials like textiles and paper.

Materials of Construction

The materials of construction for air type process dryers vary depending on the specific application and the properties of the material being dried. Common materials include:

• Carbon steel: A cost-effective option for many applications.
• Stainless steel: Offers excellent corrosion resistance and is ideal for food and pharmaceutical applications.
• Alloys: Specialized alloys may be used for high-temperature or corrosive environments.

Advantages of Air Type Process Dryers

• Relatively low capital cost: Compared to some other drying technologies.
• High thermal efficiency: Can be very energy efficient, especially direct-fired systems.
• Versatility: Can be used to dry a wide range of materials.
• Relatively simple operation: Easy to operate and maintain.

Disadvantages of Air Type Process Dryers

• Potential for product degradation: If not carefully controlled, high temperatures can damage some materials.
• Dust and emissions: Can generate dust and emissions, requiring pollution control equipment.
• Uneven drying: Can be challenging to achieve uniform drying across the entire bed of material.

Choosing an Air Type Process Dryer

Selecting the right air type process dryer depends on several factors, including:

Material properties:

• Moisture content, particle size, sensitivity to heat
• Desired moisture content: The final moisture level required in the dried product
• Production rate: The amount of material to be dried per hour
• Energy efficiency: The cost of fuel or electricity
• Environmental considerations: Regulations regarding emissions and dust

It's essential to consult with an experienced dryer manufacturer or engineer to determine the most suitable type and size of air type process dryer for your specific needs.
