With experience of over 25 years in the field of spray drying, Hemraj – India provides to their clients very cost effective solutions in supplying world-class equipment with full technical and service back up. During the last 7 years Hemraj – India has successfully supplied and installed more than 35 PSD (pilot) and ISD (industrial) series spray dryers and over 30 glass laboratory spray dryers. We have exported our spray dryers to more than 9 countries.
Glass Laboratory Spray Dryers :
A compact laboratory spray dryer with a maximum temperature of 200 maximum liquid flow rate/ evaporation capacity of 2000 ml per hour.The unit is ideal for product research and development and sample preparation in many industries.The unit incorporates all parts necessary for the spray drying process and allows control of inlet temperature, liquid sample flow, drying air flow and compressor pressure. The internal compressor activates the cleaning needle and the frequency of cleaning can be controlled.The M1 spray dryer is manufactured using the highest quality materials including 316 stainless steel, PTFE and borosilicate glass 3.3. A screw cap assembly allows for easy mounting of the atomizer directly on to the drying chamber. The atomizer and AL series nozzle is quickly dismantled for cleaning.
Pilot Spray Dryer :
M.O.C.:Stainless Steel including the supporting structure {skid mounted) with castor wheels.
GMP / Pharmaceutical standards are observed in manufacturing like avoiding crevasses, smooth finish, guards provided for electric motors, use of food grade silicon gaskets etc.
Operations – Co-Current & Counter Current.: Powder Collection – Spray Dried powder can be collected under cyclone as Single Point Discharge or optionally under chamber and cyclone as Two Point Discharge system. This gives flexibility to check particle size under chamber and Atomization – Two types of nozzle system are provided i.e. Pressure Nozzle and Two Fluid Nozzle
Features :Both exhaust and supply blowers are provided so the drying chamber is maintained under a slight vacuum hence minimizing powder loss A cleaning door is provided on the main chamber for ease of cleaning
The spray dried powder samples produced will be very much representative as of any industrial size spray dryer and hence the plant can also be used for producing small batches for sampling or for scale up Optional Programmable Logic Control (PLC) system can also be provided. Optionally available in Flame Proof construction for evaporating solvents instead of water using nitrogen.

Spray Drying :
Spray drying begins with the atomization of the feed liquid into a spray of fine droplets. Various methods are used for atomization these include using a high speed Rotary Disc, a Pressure Nozzle or a Two Fluid Nozzle.The atomized liquid is usually sprayed into a drying chamber along with a hot gas stream, either in a co or counter current flow. Consequently, the liquid’s solvent is evaporated, leaving behind the product in a form of spherical powder.The dry powder is separated from the gas stream and collected at the bottom of the frying chamber or outside of it by means of a cyclone. Thereafter the exhaust gas is treated to meet environmental requirements and is released into the atmosphere, or in case of a closed system, de-humidified, reheated and lead back into the drying chamber.
