SD-2L spray dryer

SD-2L spray dryer

The small scale spray dryer (mini spray dryer) is our best-selling laboratory equipment. It is small in size, very low in noise, and very fast in recycling.

Small spray dryer advantage:

The small scale spray dryer (mini spray dryer) produced by ZZKD is mainly used in universities, research institutes, and food, biology, beverage, chemical, material, pharmaceutical and other enterprises for laboratory research and development and production of granular powder. It is suitable for all solutions such as emulsions. The suspension has a wide range of applicability and is suitable for drying heat-sensitive materials. Such as biological products, biological pesticides, enzyme preparations, etc., and can keep the active ingredients of these materials undamaged after drying.

Small spray dryer features:

1.The spray dryer has dual control modes of automatic control and manual control.

2.The spray dryer adopts stainless steel nozzle, which has high efficiency and good atomization effect.

3.The atomization system adopts the atomization structure of two-fluid spray, and the whole machine is made of high-quality 304 stainless steel.

4.The average drying time is 0.8-1.5 seconds, and the drying speed is very fast.

5.The system adopts PID temperature control technology with real-time adjustment to make the temperature control of the whole temperature zone accurate.

6.High-efficiency volute cyclone separator for material recovery.

1. What is the hot air circulation system of The small scale spray dryer (mini spray dryer)?

In the process of spray drying, the hot air circulation system is the main power and carrier for drying, collection, and steam discharge. Adopt negative pressure suction method to make hot air circulate in the system. Its advantages are: the hot air is controlled in the system, no leakage, will not affect the experimental environment, so that the experimental staff can work in a clean experimental environment.


2. What is the working principle of The small scale spray dryer (mini spray dryer)?

After filtering and heating, the air enters the air distributor on the top of the dryer, and the hot air enters the drying chamber evenly in a spiral shape. The material liquid passes through the high-speed centrifugal atomizer at the top of the tower body and sprays into extremely fine misty liquid beads, which are in contact with hot air and can be dried into finished products in a very short time. The finished product is continuously output from the bottom of the drying tower and the cyclone separator, and the waste gas is evacuated by the induced draft fan.
