Dryers can be divided into freeze dryers, vacuum dryers, microwave dryers, spray dryers, etc. There are many ways and methods for material drying. The most common methods in our life are air-drying, sun-drying, drying, and other traditional methods.
With the development of science and technology in modern life, smart human beings have developed much faster, more efficient, and higher precision drying equipment, such as vacuum freeze dryers, vacuum dryers, microwave dryers,s and so on. The drying method of a freeze dryer can be divided into contact drying and non-contact drying (also called radiation drying). Radiation provides heat. A microwave dryer refers to the direct heating of material moisture mainly in an alternating electric field. The spray dryer is also called vapor phase drying. The material to be dried is sent to the vacuum dryer, and after evacuation, suitable steam is introduced to condense it on the object and heat the material through the heat of condensation released by it.
