1. Industrial DescriptionEdit

With the rapid rise of industries such as food, biochemistry, fine chemicals, and biology, reprocessing equipment such as dryers is also one of the essential equipment for all walks of life. First, under the requirements of today's people for drying technology, drying technology is constantly updated and developed, and drying equipment is also changing with each passing day, so as to play a greater role in people's high-quality life.

2. Working PrincipleEdit

Pressure dryer refers to a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. The dryer vaporizes and escapes the moisture (generally referring to water or other volatile liquid components) in materials by heating. To obtain a solid material with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. The working principle of the pressure dryer is to send the liquid material (filtered liquid material) into the pressure atomizer to atomize into small droplets through a high pressure of 2-20MPa. The melted droplets (with a greatly increased surface area) fully contact with the hot air to complete the drying process quickly. The finished product of powder or fine particles is obtained.

3. Application of VFDEdit

The system uses one VB/110KW with a load of 132KW exhaust fan, one VB/37KW with a load of 45KW blower, one VB/7.5KW with a load of 7.5KW material pump, which sends the liquid into the pressure mist The atomizer is atomized into small liquid droplets, the blower sends air into the pressure atomizer, and the liquid material is quickly dried with the high temperature in the atomizer, and the exhaust fan discharges the water vapor out of the atomizer, and the liquid material will It becomes the finished powder or small particles we need.

5. Application Features Edit

1）Energy saving, changing the previous fan that has been running at full speed at the rated speed, using the gate to adjust the wind pressure, so that the equipment is in a reasonable output range, so as to achieve the energy saving effect.

2） It is convenient for systematic monitoring, the VFD has complete control functions, and cooperates with other control equipment and instruments to realize centralized real-time monitoring and control of equipment operation.

3） Extend the service life of the equipment. The soft start function of the VFD makes the starting current of the motor start from zero, which reduces the impact on the power grid and the requirements for the power supply capacity,  and prolongs the service life of the equipment. The VFD has input defects and output defects. Phase, overcurrent, overload, overvoltage and other protection functions can not only protect the safety and normal use of itself, but also greatly protect the safe operation of the front and rear equipment, saving equipment maintenance costs.
