Related Hopper dryer parameters
In the raw material processing, the air is blown into the drying barrel through the dryer to obtain the raw material, and the raw material in the barrel is extracted after the production, so as to achieve the purpose of extracting the moisture content. After being heated by electric heating, the air becomes an inner screen high temperature dryer and a hole screen device, so that the hot air can be evenly dispersed in the drying barrel. Optional hot air recovery device to return the blown air. The wind enters into drying after filtering, thus forming a closed circulation loop, saving electricity.

Hopper dryer applicationr
The hopper dryer is the most effective and economical model for drying plastic raw materials. It can dry raw materials that are wet due to, packaging, transportation or recycling. The direct-type design is particularly suitable for being directly installed on the plastic molding machine for drying, which is fast and space-saving. This up-blowing hot-air dryer can provide a loading capacity of 12~1000 kg, which is divided into thirteen types.
Hopper dryers are used for mass production of a variety of raw materials. Due to the different density of each plastic raw material, the dehumidification and drying temperature of various materials are different, and the dehumidification and drying time is also different. Therefore, the hopper dryer is used alone. Reduce the drying error of each raw material, make the dried raw materials meet the standard, and make the drying time and the discharge speed of the dehumidified and dried raw materials match the time when the various raw materials are mixed. Greatly improve production quality and efficiency
This is used in blow molding workshops. The hopper dryer is directly installed on the injection molding machine. This greatly improves work efficiency and saves workshop space.
The material can be fully dried, the moisture content can be reduced, and the product quality can be improved. 2.0. Scope: 2.1. Suitable for material dryer in injection molding workshop.
3.0. Operation principle: 3.1. Plastic hopper dryer is a double-cone rotary tank. When the tank is in a vacuum state, steam or hot water is introduced into the jacket for heating. The heat passes through the inner wall of the tank to contact with the wet material, and the wet material evaporates after absorbing heat. The water vapor is pumped away through the vacuum exhaust pipe by the vacuum pump. Since the tank body is in a vacuum state, and the rotation of the tank body continuously turns the material up and down, the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.
4.0. The process operation method of the plastic hopper dryer is as follows: 4.1. High-efficiency conventional vacuum drying equipment uses steam for heating, which needs to be heated from inside to outside. The slow heating speed requires a large amount of coal. The plastic hopper dryer uses electromagnetic wave heating without a heat transfer medium. Inside the object, the heating speed is fast. 1 kW can add water at room temperature to the vacuum dryer within 3-5 minutes. The key is to integrate + improve technical management. The heat is up to 100℃, which avoids the above shortcomings, so the speed is high and the efficiency is high. , The drying cycle is greatly shortened, and the energy consumption is reduced. 4.2. The product quality is good. Compared with the conventional method, the quality of the processed product is greatly improved. 4.3. It has the functions of disinfection and sterilization, the product is safe and hygienic, and has a long shelf life. 4.4. The economic benefits are significant. 4.5. Uniform heating. Because of the heating, the material is heated from the inside to the outside at the same time. The temperature difference between the inside and the outside of the material is very small. The drying quality is greatly improved. 4.6. Easy to control, convenient for continuous production and realization of automation. 4.7. The equipment is small in size and easy to install and maintain.
5.0. Operation of the dryer: 5.1. Turn on the main power supply, restart the motor, and turn on the cooling water and air pipe. 5.2. Enter the drying temperature of the required material, adjust the position of the material level sensor according to the drying time of the material and the quantity required for production, and turn on the heating switch. 5.3. After confirming that the dryer's discharge sliding gate is closed and the discharge opening is sealed, turn on the switch of the suction machine and add the raw materials. 5.4. Confirm whether the dryer is normal, open the discharging sliding gate, turn on the suction and conveying switch, and set the conveying time. 5.5. When an abnormal alarm occurs, press the alarm to stop. According to the cause of the alarm, the alarm will be automatically released after the fault is removed. 5.6. When the dryer is in use, if the same material is continuously produced, the dryer must be cleaned every four days; when material exchange occurs, the dryer must be cleaned. 5.7. When shutting down, first perform the cooling process to about 60 degrees, and then turn off all the operation buttons on the operation interface in turn, turn off the main power supply, and turn off the water transportation.
