Primary dry powder yield (ratio of dry powder obtained by cyclone to feed main components) ≥ 97%

Dry inlet air temperature: 220 ± 5 ℃.

Dry air outlet temperature is 105-115 ℃.

Dry powder loss limit: below 1.5%.

Dry powder particle size: controlled between 20-50 μ m

The air entering the tower through the high-efficiency filter has a cleanliness level of D; There should be a leak detection port for high-efficiency filters on site; Equipped with a high-efficiency filter differential pressure gauge, there is a uniform section before and after the differential pressure gauge, and the display of the differential pressure gauge is stable. The position of the differential pressure gauge should be easy to observe;

The seal ring of the spray dryer shall be made of the same material as the high-efficiency filter to ensure the high temperature resistance capability and time limit. The manufacturer shall provide the high temperature resistance certificate;

The three-stage air intake system should be designed to achieve effective concentration during leak detection;

The spray dryer shall be designed with a closed aggregate bin for receiving materials. Equipped with automatic feeding, temperature adjustment, spray drying, unloading, dust removal, and cleaning;

The process of liquid feeding, drying, and discharging is completed in one go. This machine is designed according to the standard for precision drying and packaging equipment. The internal and external surface smoothness, disassembly method, cleaning function, filtering device, etc. of the equipment should be designed in accordance with the relevant requirements of D-level clean area equipment.

At the bottom of the tower, there is no discharge, and the first and second stage cyclones pass through the collection bin and are transported by vacuum to the downstream dissolution process.
