Infrared Heating & Drying in Food & Agriculture

The equipment using нүүрстөрөгчийн шилэн халаагчийн элементүүд as a far-infrared radiation source is referred to as far-infrared heating equipment. The advantages of infrared heating and drying include:

• High thermal radiation rate
• Low heat loss
• Fast heating speed
• High heat transfer efficiency
• Certain penetration capability
• High heat absorption rate
• Convenient equipment maintenance

However, for various reasons, infrared heating and drying technology has not been widely used in the food and agricultural product industries at this stage. The main reasons include:

• The wide range of moisture content in food affects the infrared heating characteristics.
• Compared with traditional hot air circulation, people’s understanding of the spectral characteristics of infrared radiation is not deep enough. Many large companies are unwilling to take on the experimental risks of new heating methods.
• The penetration of infrared radiation has certain limitations, making it unsuitable for heating and drying thicker products.

There are two main types of far-infrared drying equipment:

1. Sealed Box-Type Heating Furnace: This type of equipment, also known as an oven or baking oven, has only one entry and exit door.
2. Continuous Heating Equipment for Production Lines: This type of far-infrared heating and drying equipment is used on production lines to continuously heat, dry, and sterilize materials. It includes a material conveying device that inputs materials from one end and outputs them after processing from the other end. This type of equipment is generally designed in the form of a channel, hence it is called a drying tunnel or sometimes referred to as a tunnel furnace.

Common far-infrared heating elements used in far-infrared heating and drying equipment for the food industry include:

• Linear carbon fiber heater elements
• U-shaped carbon fiber heater elements
• Special-shaped carbon fiber heater elements
