As the person technology is getting better and better, its application field will be also more and more, person who believe in the near future vendors would also more and more, this to promote the development of the person who plays an important role. Cold drying machine belongs to a kind of cold dry equipment, mainly has the sleeve cold dry machine, the rotary tube cold dry machine, turns the drum cold dry machine and so on type. Rotary cold drying machine can dry a variety of materials, including sawdust material. Shengmingda refrigeration equipment through the study found that the use of radiation heat transfer to the end of the sawdust to the best effect. However, it is necessary to master certain skills to make the heat transfer better. Follow us to understand the cold and dry characteristics of radiation heat transfer:
The use of a rotary cold dryer does not require any medium, as long as it is above absolute zero, any object can emit radiant energy. When radiant energy is projected onto an object, some of the energy is absorbed, another part of the energy is emitted, and some energy is passed through the object. Radiative heat transfer can become the main heat transfer mode only when the temperature of the object is very different.
It is found that the radiative heat transfer is a phenomenon of electromagnetic wave transmission. High and low temperature objects can transmit heat to each other in the form of electromagnetic waves and absorb energy from each other. The final result is a heat transfer from a high temperature object to a cryogenic object. This heat transfer does not require any medium. The heat radiation not only produces energy transfer, but also the conversion of energy form. That is, in the heat release, the heat energy is transformed into radiant energy, which is transmitted to the space in the form of electromagnetic waves. When encountering another object that can absorb radiant energy, it is converted into heat by some or all of its absorption.
This is the heat transfer method of the latest research of the rotary cold dry machine factory, which has been successfully applied to the sawdust. In the later stage of cold drying machine equipment research and development, will develop faster, more energy efficient cold dry way, make a variety of materials to achieve quick and cold drying effect.
