Hot air circulation dryer, also known as a convection dryer or furit dryer, is a type of industrial equipment used to remove moisture from materials. It works by circulating heated air over the material to be dried, which causes the water or other solvents to evaporate.
WORKING PRINCIPLE
The series of products completely adopt axial fan equipped with automatic constant temperature control system,whitch is provided with computer contorl system for option. The working principle is to make use of the team or electric heat source through heating the air by heat exchanger and adopting the axial fan as the driving power,the moisture content of hot material is reduced so as to realize the purpose of drying.
According to different produts,we can provide different drying trays in order to save the energey,including the material. In addition, we can also provide different drying capacity, such as 20pcs,48pcs, 96 pcs and so on.
Main Components of Hot Air Circulation Dryer Machine
1. Heating System: This can be powered by electricity generally, depending on the specific design and application. The heating system raises the temperature of the air, which is then circulated through the drying chamber.
2. Fan or Blower: A fan or blower is used to circulate the heated air within the drying chamber. This ensures that the air is evenly distributed and that all parts of the material are exposed to the drying process.
3. Drying Chamber: This is the enclosed space where the material to be dried is placed. The chamber is designed to allow for efficient air circulation and to minimize heat loss.
4. Exhaust System: As the moisture evaporates, it needs to be removed from the drying chamber. An exhaust system, often including a dehumidifier or condenser, is used to remove the moist air and maintain the desired humidity level inside the chamber.
5. Control System: Modern hot air circulation dryers are equipped with control systems that monitor and adjust the temperature, air flow, and humidity levels to ensure optimal drying conditions. These systems can be manual, semi-automated, or fully automated.
As for the drying trays,we can also recommend different material according to different product drying.For example, SUS 304,mesh belt tray and some plastic trays.
Food Dryer Advantages
1.Efficiency: Hot air circulation dryers are generally more energy-efficient compared to other types of dryers.
2.Uniform Drying The even distribution of heated air ensures uniform drying, which is crucial for maintaining product quality.
3.Versatility: They can be adapted to a wide range of materials and applications.
4.Scalability: Available in various sizes, from small benchtop units to large industrial systems.
Fruit Drying Machine Applications
Hot air circulation dryers are widely used in various industries, including:
Food Processing: Drying fruits, vegetables, grains, and other food products,as well as some fruit drying
Pharmaceuticals: Drying pharmaceutical ingredients and products.
Chemicals: Drying chemicals and other industrial materials.
Textiles: Drying fabrics and textiles.
Wood and Paper: Drying wood, paper, and pulp.
Plastics: Drying plastic pellets and other materials.
