Infrared dryer, also known as infrared radiant heater, is a device that converts electrical energy or other forms of energy into radiant energy. It is a key component in infrared heating systems. Infrared dryer is mainly composed of two parts, namely heat source and radiation matrix. .
The far-infrared sterilization dryer is suitable for drying and sterilizing medicinal glass bottles such as pharmaceutical company oral liquid bottles and antibiotic vials. The machine is an integral tunnel structure, which is divided into three parts: preheating zone, high temperature sterilization zone and cooling zone. The container is subjected to short-time high-temperature sterilization using the principle of far-infrared sterilization.
Infrared light is also called "infrared light." In the electromagnetic spectrum, electromagnetic radiation having a wavelength between red light and microwave. Outside the range of visible light, the wavelength is longer than red light and has a significant thermal effect. Infrared drying technology uses its unique thermal effects. Infrared light is easily absorbed by objects and has the characteristics of radiation, penetrating power and electromagnetic waves having special affinity for polar substances such as water molecules. It penetrates into the interior of the material and transforms into the internal energy of the object, so that the object can be dried in a very short time. The required thermal energy, both internal and external, is more effective and completely removes the bound water in the material, thereby achieving a more ideal drying effect, thereby avoiding energy loss caused by heating the heat transfer medium, and beneficial energy saving, and at the same time infrared It is easy to produce, has good controllability, and is heated quickly and has a short drying time.
The infrared light has a wavelength range of approximately 0.75 nm to 1000 nm, and is named because its wavelength is outside the red light wavelength (about 0.6 nm to 0.75 nm). In the conventional industrial thermal range below 2000 ° C, infrared is the most important heat ray.
People sometimes divide infrared rays into several cells such as “near-infraredâ€, “mid-infraredâ€, and “far-infraredâ€. The so-called far, medium, and near are the relative distances from the red light in the electromagnetic spectrum. . Infrared radiation is heat radiation, and several basic concepts of thermal radiation are applicable to infrared radiation heat transfer processes.
advantage
1. The infrared dryer uses electric energy to generate infrared rays, so that the dried and dried objects have the effect of absorbing permeation from the surface to the inside. The drying rate is higher and the thermal efficiency is higher, and no shadow is left when irradiated.
2, energy saving and consumption reduction from the dry way to start three ways to save energy:
(1) Combined drying method Due to the diversity of materials and the complexity of their properties, drying materials with a single drying method often fails to meet the quality requirements of the final product, or consumes too much energy. If two or more drying methods are combined, different drying methods in different moisture stages of the material can not only effectively improve drying efficiency, save energy, but also better control the entire drying process, which helps to obtain high The quality of the product, this drying method is called combined drying.
(2) Wind direction control method Downstream drying and countercurrent drying are the two most common types of air supply, each with its own advantages and disadvantages. Mixed-flow drying combines the advantages of both, which makes the drying uniform, accelerates the drying speed, shortens the drying time and saves energy.
(3) Segment drying method The same drying method has different drying stages, and different drying parameters can be adopted according to the characteristics of the stage of the material, which is called section drying.
The above is for everyone to share today, about the working principle and characteristics of the far-infrared sterilization dryer , I hope to be helpful to everyone.
