How does a vacuum spray dryer achieve energy savings?

Vacuum spray dryer actually refers to a device that can play a drying role. It can meet the requirements of continuous feeding and discharging under vacuum conditions, and the amount of feed can be set according to needs, and the operation is very flexible. . In addition, the heating system can be used in various forms such as steam, hot water or electric heating. During the drying process, we can make any adjustments in the temperature range of 25 ° C - 80 ° C. Generally, after 20 minutes to 60 minutes, the dryer starts to discharge continuously until the drying task is completed. Since the track of the equipment is made of Teflon material, it can not only ensure smooth and reliable performance, but also make the heating area more uniform during operation. Of course, its speed can also be adjusted according to actual needs. In addition, it can be used in combination with different fabrics to meet the drying requirements of different materials, such as the ability to dry materials such as liquids, extracts and powders.

In addition, the vacuum spray dryer is specially equipped with an automatic pulverizing system under vacuum, so the user can select the number of dry granules as needed. The unit is also equipped with an in-place cleaning system that automatically cleans and saves a lot of time. In the process of operation, the equipment not only has low energy consumption, but also does not generate harmful substances, and the working noise is also small.

In order to improve the energy efficiency of the dryer, based on the full study of its performance, some effective measures for energy saving and consumption reduction were summarized. First, increase the temperature of the hot air into the tower. Under the condition that the temperature of the tower is constant, the higher the temperature of the hot air entering the tower, the more heat is transferred to the mud droplets, and the more water is evaporated by the unit hot air. In the case of a constant production capacity, the amount of hot air required is reduced.

This means that heat loss can be reduced, which reduces the heat consumption of the vacuum spray dryer . Secondly, the temperature of the off-column of the hot air can be appropriately reduced. When the temperature of the hot air inlet tower is constant, the temperature of the hot air off the tower can be lowered, the heat taken away by the hot air from the tower can be reduced, and the hot air can be utilized to a large extent. Heat to dry the mud droplets.

The third is to increase the temperature difference between the hot air entering the tower and the hot air from the tower. By increasing the temperature of the hot air into the tower or lowering the temperature of the hot air from the tower, the temperature difference between the hot air entering the tower and the hot air from the tower is increased, and the hot air is fully utilized. The heat evaporates the moisture of the mud droplets to achieve the purpose of improving the thermal efficiency of the spray drying tower and reducing energy consumption.

Fourth, the production efficiency of the spray dryer can be improved by reducing the moisture content of the ceramic slurry. In fact, the ceramic slurry has good fluidity and easy atomization, which can effectively shorten the spray drying time. Adding a suitable water reducing agent to the ceramic slurry can reduce the moisture content of the slurry.

Fifth, the temperature of the mud can be appropriately raised, which can reduce the annual, thereby improving the atomization effect of the spray dryer and reducing the heat consumption of the spray-drying powder.

Sixth, the waste heat is recovered through the heat exchanger to save energy. That is to say, during the use of the vacuum spray dryer , the use of the heat exchanger will enable more sufficient use of heat, thereby increasing the atomization efficiency of the spray dryer and reducing energy consumption.
