With the promotion of energy conservation and environmental protection and related measures, how to realize energy saving and environmental protection of spray dryer has become a problem that the drying equipment manufacturers have to think about. On the basis of full research on its performance, some manufacturers have summarized some useful energy-saving and consumption reduction measures, which are briefly sorted out by the Xiaobian.

一，提高热风的进塔温度。据了解，在离塔温度不变的情况下，热风的进塔温度越高，传递给泥浆雾滴的热量越多，单位热风蒸发的水分越多。在生产能力恒定的情况下，所需热风量减少，如此便可以减少热量损失，降低真空喷雾干燥机的热量消耗。

1、 Increase the inlet temperature of hot air. It is understood that under the condition of constant temperature away from the tower, the higher the inlet temperature of hot air, the more heat transferred to mud droplets and the more water evaporated by unit hot air. When the production capacity is constant, the amount of hot air required is reduced, so that the heat loss can be reduced and the heat consumption of the vacuum spray dryer can be reduced.

二，可以适当降低热风的离塔温度。在热风的进塔温度恒定不变的情况下，降低热风的离塔温度，可以减少热风离塔时所带走的热量，较大限度地利用热风的热量来干燥物料。

2、 The off tower temperature of hot air can be appropriately reduced. When the inlet temperature of hot air is constant, reducing the temperature of hot air leaving the tower can reduce the heat taken away by hot air leaving the tower, and make greater use of the heat of hot air to dry materials.

三，增大进塔热风与离塔热风之间的温度差，通过提高热风的进塔温度或降低热风的离塔温度，增大进塔热风与离塔热风之间的温度差，充分利用热风的热量蒸发物料的水分，从而达到提高喷雾干燥塔的热效率、降低能耗的目的。

Three, increasing the temperature difference between the hot air and the hot air from the tower, increasing the inlet temperature of the hot air or decreasing the temperature of the hot blast tower, increasing the temperature difference between the hot air and the hot air, and making full use of the heat of the hot air to evaporate the moisture of the material, so as to raise the thermal efficiency and reduce the energy consumption of the spray drying tower.

四，可以通过降低物料的含水率，来提升喷雾干燥机的生产效率。事实上，流动性好、易于雾化的物料，可有用缩短喷雾干燥时间，在物料中添加适宜的减水剂，可降低含水率，加速干燥时间。

Four, the production efficiency of spray dryer can be improved by reducing the moisture content of the material. In fact, fluidity and atomization can shorten the time of spray drying. Adding suitable water reducing agent can reduce moisture content and accelerate drying time.

五，可以通过热交换器来回收利用废气余热，从而达到节省能源的目的。例如，在使用真空喷雾干燥机期间，利用热交换器将能够更为充分的利用热量，从而提高喷雾干燥机的雾化效率，减少能耗。

5、 The waste heat of waste gas can be recovered through heat exchanger, so as to save energy. For example, during the use of vacuum spray dryer, the heat exchanger will be able to make full use of heat, thereby improving the atomization efficiency of spray dryer and reducing energy consumption.

除了对喷雾干燥机的降耗有改进要求以外，一些用户反映，在对实验室天然产物提取物做喷雾干燥时，经常会产生黏壁问题，困扰科研人员的操作。

In addition to improving requirements for energy saving and consumption reduction of spray dryer, some users have shown that sticky problems often occur in spray drying of natural products extracts from laboratories, which may interfere with the operation of scientific researchers.
