1. Introduction.
Rake vacuum dryer is a common drying equipment, which is widely used in chemical, pharmaceutical, food and other industries.
It has the characteristics of simple structure, convenient operation and good drying effect, so it is favored.
Second, the working principle.
The working principle of the rake vacuum dryer is to dry the wet material quickly through vacuum technology and heating technology.
First, the wet material is placed in the drying chamber, and then the vacuum pump is activated to pump the air out of the chamber to create a highly vacuum environment.
Next, a heater is used to heat the material and evaporate the water.
At the same time, the material is continuously stirred by a rake to make it evenly heated and the drying speed is accelerated.
The evaporated water is discharged through a vacuum pump to complete the drying process.
3. Advantages. 1.Good drying effect: The rake vacuum dryer can be dried at a lower temperature, which avoids the thermal decomposition and deterioration of the material at high temperature, and maintains the original properties and activity of the material.
2.Easy to operate: The operation of the machine is very simple, just set the relevant parameters, and then start the machine to dry automatically.
At the same time, the equipment has an automatic control system, which can monitor temperature, vacuum and other parameters in real time, and the stability and safety of the drying process.
3.Wide range of application: The rake vacuum dryer is suitable for drying all kinds of wet materials, including powder, granular and colloidal materials.
Therefore, it has a wide range of applications in chemical, pharmaceutical, food and other industries.
Fourth, the application case.
1.Chemical industry: Rake vacuum dryers are widely used in the chemical industry.
For example, in a chemical plant, the equipment is used to dry chemicals in powdered form.
By controlling the heating temperature and vacuum, it is possible to ensure that the chemicals do not decompose and deteriorate during the drying process, resulting in the quality and safety of the product.
2.Pharmaceutical industry: Rake vacuum dryers are also widely used in the pharmaceutical industry.
For example, in a pharmaceutical company, the device is used to dry the moisture in the drug to improve the stability and shelf life of the drug.
By controlling the drying temperature and time, the quality and effectiveness of the drug can be ensured.
3.Food industry: Rake vacuum dryers are also used in the food industry.
For example, in a food processing plant, the equipment is used to dry fruit and vegetable products.
By controlling the drying temperature and vacuum, the color, taste and nutrients of fruit and vegetable products can be maintained, and their shelf life can be extended.
