1. What is an Industrial Cold Air Dryers?
Industrial cold air dryers use cold drying technology, operating at lower temperatures than traditional heat dryers. This equipment can dry a wide range of products, including flowers, fruits, seeds, meat, seafood, and high-value items like cordyceps and ginseng. The drying process preserves the aroma, taste, color, and nutritional value of the products.
These dryers are highly efficient, reducing electricity consumption by 30-50% compared to heat dryers. This efficiency makes them a popular choice for businesses in Dong Nam. We offer various models with capacities ranging from 60kg to 500kg per batch, and up to 3 tons per batch.
2. Advantages of Industrial Cold Air Dryers
Dong Nams industrial cold air dryers offer several key advantages over traditional models:
■ User-Friendly Interface: The machines feature an intuitive touch screen interface in Vietnamese.
■ Efficient Drying Technology: The system separates moisture and circulates drying air, speeding up the drying process.
■ Low Drying Temperatures: Operating at temperatures between 20-60°C, these machines help maintain the original color, aroma, taste, active ingredients, and nutrients of the raw materials, enhancing the final products value.
■ Cost-Effective Operation: Investing in an industrial cold air dryers can lower operating costs compared to multiple dryers, and significantly reduce electricity usage.
■ Environmental Friendliness: Electric heating eliminates the need for polluting fuels.
■ High Standards of Food Safety and Hygiene: The design saves on labor costs and ensures safe and hygienic drying processes.

3. Applications of Industrial Cold Air Dryers
► These dryers are ideal for facilities producing dried foods on a large scale, with capacities ranging from 500kg to 3 tons per batch. They are particularly suited for high-value products like cordyceps, birds nest, ginseng, deer antlers, and macadamia nuts.
► The low-temperature drying process preserves the quality of these products, making cold air dehydration a preferred method for businesses seeking to maintain high standards.
4. Design and Structure
The body and casing of these dryers are made of durable, rust-resistant 201 stainless steel, while the drying trays are constructed from 304 stainless steel, ensuring safety and compliance with GMP factory standards.

6. Operating Principle of Industrial Cold Air Dryers
Unlike traditional heat drying, cold air drying technology uses low temperatures and moisture separation to dry raw materials. The process begins with the removal of moisture from the air, producing a stream of dry air. This air is then heated by a heat pump to the desired temperature before being circulated into the drying chamber.
Dried herbals retain their color
Inside the chamber, the dry air absorbs moisture from the raw materials due to the significant humidity difference. The moisture-laden air is then drawn to a condenser, where the water is separated and collected in a recovery tray before being discharged. The remaining dry air is reheated and recirculated through the dehumidification process until the products reach the desired dryness level.
This fully enclosed drying process preserves the maximum flavor of the raw materials. The low temperature ensures that the color of the final product remains as vibrant as the original.
