working principle

The material is fed into the dryer by the lifting feeder, and the dried material is evenly spread on the moving conveyor belt while moving and drying; Install height adjustable infrared heaters on the upper and lower parts of the conveyor belt, so that the internal molecules of the material absorb far-infrared radiation energy after being irradiated by far-infrared radiation, thereby achieving a baking effect. Equipped with a forced circulation fan, the dry and hot air is forcefully sprayed onto the material layer; Conveyor belt assisted rack type disturbance device flips the material layer to evenly heat the product.

Multi layer mesh belt layout form extends material retention time. The hot air is forcibly transported by the induced draft fan and designed with special laminar flow, which can reduce heat loss and energy consumption during heating.

This production line is a far-infrared drying equipment widely used in industries such as agricultural products, food, traditional Chinese medicine decoction pieces, catalysts, papermaking, coating, etc. for drying or baking particles, sheet materials, and film coating to enhance fragrance.

Features of the equipment

1. High drying rate: Infrared dryers use electrical energy to generate infrared radiation, which causes the object being dried to absorb and penetrate from the surface to the interior, making them particularly suitable for drying thin films.
2. High thermal efficiency: Compared with conventional electric heating tubes, the electric thermal conversion efficiency is increased by 20-30%, and through directional radiation, the drying speed is accelerated, saving energy.
3. Accurate temperature control, capable of meeting segmented drying: A fixed proportion of heat generation can be achieved through a temperature controller to meet different process requirements.
4. Fast heating and cooling rate: The heating and cooling of infrared heating elements can be completed within 15 minutes, which is shorter than traditional operations that often take 0.5-1 hours.
5. Safe and reliable: Infrared radiation has therapeutic effects, based on the thermal effect. Compared to microwave drying and heating, it is safe and reliable, and can be operated with confidence.

Introduction to Infrared Thermal Radiation

As we all know, white light is a mixture of many colors of light. The rainbow after rain can show us seven types of visible light, which are red, orange, yellow, green, blue, indigo, and purple. In the spectrum, there are still many invisible light rays, among which the wavelength (length of light waves) of 0.75-1000 μ m is called "infrared", also known as "infrared thermal radiation", discovered by German scientist Huxler in 1800. All substances above absolute zero (-273 ℃) can produce infrared radiation, which modern physics refers to as thermal radiation. Infrared radiation has therapeutic effects, and the basis of infrared therapy is the thermal effect. Under infrared irradiation, tissue temperature increases, capillaries dilate, blood flow accelerates, substance metabolism is enhanced, tissue cell vitality and regeneration ability are improved, and the wavelength of infrared is greater than that of visible light.

Infrared radiation can be divided into three parts, namely near-infrared radiation, with a wavelength between 0.75 and 1.50 μ m; Mid infrared, with a wavelength between 1.50-6.0 μ m; Far infrared radiation with a wavelength between 6.0 and 1000 μ m. Decades ago, space scientists conducted investigations and studies on the human living conditions inside spacecraft that were in a vacuum, weightlessness, ultra-low temperature, and overload state, and found that far-infrared radiation with wavelengths of 8-14 microns was an essential factor for biological survival. Therefore, people refer to this wavelength of far-infrared radiation as the "light wave of life". This wavelength of light is similar to the wavelength of far-infrared radiation emitted by the human body, and can produce the most effective "resonance" with water molecules in biological cells. At the same time, it has permeability and effectively promotes the growth of animals and plants.
