Distinguishing DeAir.Re-H and Daxwell Heat-Pump Dryers

Technology heat pump dryer (heat pump dryer) was born as an advanced solution based on the principle of thermodynamics, transporting heat from the natural environment effectively. This technology brings many outstanding advantages, especially the ability to save significant energy and preserve the quality of the product after drying.

When learning about heat pump dryers, you can see many different product lines, even within the same brand. This article will help you distinguish between heat pump dryers, especially delving into the differences between DeAir.Re-H heat-pump dryers and Daxwell heat-pump dryer - two prestigious product lines from DeAir, an expert in the field of humidity treatment in Vietnam.

What is a Heat Pump Dryer?

A heat pump dryer is a modern drying device that operates on the principle of an air conditioning system but is optimized to provide high heat energy. Instead of generating heat directly, the heat pump dryer uses the refrigerant circulation cycle to absorb heat from the air and compress this heat to a higher temperature for use in the drying process.

The heat pump drying process takes place in a closed loop: moist air from the drying chamber is drawn through the evaporator to remove moisture. The dry air then passes through the condenser, receiving heat from the compressed refrigerant, becoming a hot, dry air stream that is blown back into the drying chamber to dry the product. This cycle continuously reuses heat, helping to save significantly energy, up to 70% compared to traditional drying methods.

Industrial and Residential Heat Pump Dryers: Important Differences

Before going into the DeAir product lines, it is necessary to clearly distinguish between industrial heat pump dryers and residential ones (such as household clothes dryers). Industrial heat pump dryers have distinct differences:

• Capacity and scale: Much larger, handling large volumes of products in continuous production.
• Design and durability: Made from durable materials, resistant to harsh environments and continuous operation.
• Temperature range & Control: Wider drying temperature range and more complex, precise control system, allowing customization of drying parameters.
• Application: Used in the manufacturing and processing industries of agricultural products, food, pharmaceuticals, and seafood.
• Cost: Initial investment costs may be higher, but long-term operating costs are lower thanks to energy saving.

• Intelligent control system (PLC/HMI):
  • Precise control: PLC allows programming of drying parameters (temperature, humidity, time...) accurately according to each type of drying material, ensuring the quality of the dried product is uniform and meets the requirements.
  • Visual monitoring: The HMI touch screen provides an intuitive interface, helping the operator easily monitor the operating parameters of the dryer in real time and make quick adjustments.
  • Optimize performance: The PLC controls the components of the heat pump system (compressor, fan, valve...) in coordination, helping the system operate at the highest efficiency, energy saving.
  • Stability and reliability: Precise control helps the system operate stably, reduces problems and prolongs life.
  • Automation: Open expand the ability to automate the production process.
• Diverse temperature range: Daxwell offers many models with different operating temperature ranges, meeting a variety of drying needs:
  • D series: 40°C - 60°C, suitable for drying products sensitive to high temperatures (medicinal herbs, vegetables and fruits).
  • M series: 50°C - 80°C, suitable for drying processes requiring higher temperatures.
  • S series: 25°C - 80°C, temperature range widest range, suitable for drying a variety of products, including cold drying at low temperatures.
• Application: Daxwell is widely used in many industriesIndustries such as agricultural processing (rice, corn, coffee, pepper, vegetables and fruits), food (dried fruit, confectionery, processed food), pharmaceuticals (medicinal materials, herbs), seafood (fish, shrimp, squid) and other industries. The ability to customize the drying cycle helps the machine to suit the characteristics of each type of material.

Overview Comparison of DeAir.Re-H and Daxwell

Factors to consider when choosing a heat pump dryer
