microwave drying Better than traditional drying

Drying generally refers to various operations to remove moisture or other moisture from wet materials . For example, wet materials are exposed to the sun in daily life to remove moisture . The traditional heating method is to heat from the outside to the inside through radiation, convection and conduction , To avoid excessive temperature gradient , The heating speed cannot be too fast , The components of mixed materials in the same reaction device cannot be selectively heated . Today, Xiaobian will take you to understand the advantages of microwave drying over traditional drying .

　　 one 、 microwave heating When the sample is heated evenly , Small temperature gradient . During traditional heating , Heat transferred from the surface of the sample to the interior , Because the surface temperature is higher than the center temperature , Therefore, a large temperature gradient will be generated , May lead to non-uniformity of submicroscopic structure and performance . Microwave heating is generated inside the heated object , The heat source comes from the inside of the object , Heating evenly . At the same time, due to " Heating both inside and outside " Greatly reduces heating time , High heating efficiency , It is conducive to improving product output . And the inertia of microwave heating is very small , It can realize fast control of temperature rise and fall , It is conducive to automatic control in continuous production .

　　 two Microwave has the characteristics of selective heating of substances . Because the ability of materials to absorb microwave energy depends on their own dielectric properties , Therefore, each component in the mixed material can be selectively heated . The gas phase temperature can not be too high by using selective heating , So as to improve the selectivity of the reaction .

　　 three Microwave heating can quickly control the reaction temperature . Traditional drying method , Such as steam heating, electric heating, infrared heating, etc , To reach a certain temperature , It takes some time , In case of failure or stop of heating , The temperature drops for a long time . However, microwave heating has no hysteresis effect , When the microwave source is turned off , No more microwave energy to matter , This feature can be used to respond to high requirements for temperature control .

　　 four Strong microwave heating penetration , High energy utilization efficiency , The material heats up very quickly , Proper application can speed up the processing of materials , But if the control is not good, it will also cause adverse effects .

5、 Microwave heating environment is clean, sanitary and pollution-free . Microwave drying equipment Smaller footprint than traditional drying equipment , And avoid high ambient temperature , The working environment of workers has been greatly improved .

Structure analysis of microwave drying equipment

Now in life , Microwave drying equipment is very common , There are also many large-scale microwave drying equipment used in factories and other places , It won everyone's favor . Now let's analyze the structure of microwave drying equipment .

　　 one Innovative tape wiping device , Effectively clean the damage to the conveyor belt caused by the oil stain generated by materials during processing , This is not available on the imitation equipment .

　　 two Microwave drying equipment adopts scientific chamber structure , Consistent microwave emission conducive to processing , Guarantee, energy conservation and consumption reduction .

　　 three . No waste of raw materials : The inlet and outlet are equipped with a sealing device and a four stage device to prevent microwave leakage , Ensure the safety of operators .

　　 four . Due to the particularity of the material , Our products are designed to prevent materials from slipping , This avoids the trouble brought to the operator by the long time processing materials falling to the bottom of the chamber and the hidden trouble caused by other faults .

　　 five The microwave drying equipment adopts humanized intelligent and reasonable central program control to make the operation simple and intuitive .

　　 six The production equipment is made of integral main body made of profiles , Beautiful and generous .

　　 seven . Save human resources : The unique outlet design of microwave drying equipment can effectively separate dry products and sundries , Reduce the complexity of the next process and labor intensity of personnel .

Advantages of microwave dryer

The main components of the microwave dryer are made of metal , Generally not easy to damage , Only the conveyor belt is a vulnerable part , Therefore, attention should be paid to this in normal use , Metal impurities are strictly prohibited during operation . Now let's introduce the advantages of microwave dryer .

　　 one Efficient : Conventional vacuum drying equipment uses steam for heating , It needs to be heated from inside to outside , Slow heating requires a lot of coal , The microwave vacuum drying equipment uses electromagnetic wave heating , No heat transfer medium required , Directly heated into the object , High heating speed , Compared with conventional drying technology, microwave dryer can improve work efficiency by more than four times .

　　 two Uniform heating : Because microwave dryer belongs to microwave heating , It is to heat materials from inside to outside at the same time , The internal and external temperature difference of materials is very small , There will be no inconsistency between internal and external heating during conventional heating , So as to produce a puffing effect , Beneficial to pulverization , The drying quality is greatly improved .

　　 three , easy to control : Microwave dryer is convenient for continuous production and automation , Because the microwave power can be quickly adjusted and has no inertia , Easy to control immediately , You can use the 40℃-100℃ Arbitrary temperature adjustment between

　　 four Small equipment volume , Easy installation and maintenance

　　 five Good product quality , Compared with conventional methods , The quality of processed products has been greatly improved .

　　 six Microwave has the efficacy of disinfection and sterilization , Product safety and health . Long shelf life .

　　 seven Significant economic benefits .

From the advantages of microwave dryer introduced above , Energy saving, consumption reduction, product quality improvement, safety and health, low equipment investment cost and other aspects can show its remarkable economic and social benefits .

Microwave drying equipment Unique features of heating

Microwave technology can be used independently in the drying process , It can also be combined with the traditional heating method . An example of microwave drying of food is potato chips , The potato chips are fried with hot oil to form a unique color , then , Then dry with microwave and hot air at the same time . What I introduce to you is Microwave drying The uniqueness of equipment heating is as follows :

　　 one It can go deep into food and heat , Therefore, the heating is fast .

　　 two Clean heating mode , The environment is not polluted , It is easy to clean the furnace after heating .

　　 three . Different processing technologies can be selected , for example , The food in the container or package can be heated . in addition , Food drying is even .

　　 four Easy to control heating temperature , Automate .

　　 five Heating has sterilization and drainage effects at the same time .
