Pharmaceutical industry: tablets, granules, capsules and granules; Low sugar, sugar free traditional Chinese patent medicines and simple preparations granules;
Food: cocoa, coffee, milk powder, granular fruit juice, seasonings, etc;
Other industries: pesticides, feed, fertilizers, pigments, dyes, etc.
The spray drying granulator integrates spray drying/fluidization granulation to realize one-step granulation of liquid materials;
It adopts spray process, especially suitable for micro auxiliary materials and heat sensitive materials, and its efficiency is 1-2 times higher than that of FL boiling granulator;
Some products have a final moisture content of up to 0.1%, equipped with a powder return device, with a particle formation rate of ≥ 85%, and can produce 0.2-2mm particles;
Improved design of internal mixed multi fluid atomizer, capable of handling some specific weights up to 1.3g/cm3The extract.
At present, it shouldSpray drying granulatorThe series of products have achieved PGL-150B, with a processing capacity of 500kg per batch.

Selection example: It is required to process a liquid extract amount of I=120kg (with a solid content of 30%) and a seed amount of II=60kg per batch. The theoretical finished product amount M=mI+mII=120kg * 30%+60kg=96kg can be obtained from I and II. The working time T=120kg/30kg/h=4h. The boiling amount can be found in the technical parameter column as the standard load range. Therefore, PGL-30B type is more suitable for completing two batches per shift.
