Microwave refers to electromagnetic waves with a frequency of 300 megahertz to 300 megahertz. The medium material consists of polar molecules (water molecules) and non-polar molecules. Under the action of the electromagnetic field, these polar molecules turn from the original random distribution to the polarity alignment according to the electric field. Under the effect of high-frequency electromagnetic fields, these orientations change according to changes in the alternating electromagnetic field. This process results in the movement of molecules and the mutual friction effect. Under the action of an electromagnetic field of 2054 megahertz, water molecules can make 2.4 billion per second. Thousands of displacements, which generate heat. At this time, the field energy of the alternating electromagnetic field is converted into the thermal kinetic energy in the medium, and the temperature of the medium is continuously increased.
In microwave drying applications, there are generally two ways. The first is the conventional drying equipment, which is mainly used for the drying of materials with low drying temperature requirements and no volatile substances in the process (it can be dried to a moisture content of several hundred percent in a few to ten minutes, and the temperature can be controlled 100 degrees or less; the other is the microwave vacuum drying method (including static basket type microwave vacuum drying equipment and dynamic stirring microwave vacuum drying equipment), mainly used for the drying of heat-sensitive materials and the drying of volatile materials.
Zowell XPC15 Pallet truck 1500kg is a material handling equipment mainly used in the transfer of materials in pallet inside and outside the production line and warehouse. The pallet truck is only used for plane transportation for no lifting mast. Although the pallet truck cannot lift the goods, but the purchase and maintenance costs are quite lower than other forklifts. Zowell XPC15 electric pallet trucks is equipped with AC drive motor and multi-functional handle, emergency switch, dual balance wheel as well as side loading battery for safety, efficiency and less fatigue in operation. Buffered pedal also extends the flexibility for various scenarios.
