Sci-tech Spray Dryer Model TH 042 is specially designed for practical hands-on training on spray dryer and process control study. The equipment consists of either laboratory or optionally, industrial grade instrumentation to exhibit a realistic working environment of standard industrial control loop.

It is equipped with a peristaltic pump that transfers the liquid from a container through a small diameter jet into the drying chamber. Compressed air enters the outer tube of the jet which causes the liquid to emerge as a fine atomized spray into the drying chamber. Heated air is blown through the drying chamber evaporating the liquid content of the atomized spray.

The solid particles shall be separated from the exhaust air flow by a cyclone and collected in a sample bottle. Temperatures and pressures throughout the process are indicated by temperature and pressure transmitters.

Sci-tech Spray Dryer Model TH 042  can be, optionally connected to ‘Sci-CalVaq’ SCADA system. All the process variables shall be recorded. The collected data shall be in ASCII format and it can be exported into Microsoft Excel format for reporting and further data analysis. The process variables can be monitored remotely via Internet-Of-Thing (IoT). Instructor and trainee can monitor and view the process variables in real time via the smart devices, i.e., smart phone, tablet or remote PC.

Sci-tech Spray Dryer Model TH 042 is designed for the rapid spray drying processes involving aqueous solutions, suspensions and colloids. The unit should analyze this drying method for obtaining powered products from solutions, suitable for during thermo-sensitive products. This spray dryer has been designed for educational and research laboratories and it enables to obtain the product micronized in short time, as well as valid data for scale up. The trainer consists of a heating system, drying chamber, collecting bottle, spray nozzle, peristaltic pump. The solution is sprayed into hot air inside the drying chamber using stainless steel spray nozzle. The dried products are collected in collecting bottle. The hot air temperature can be controlled using a programmable controller. All parts in contact with the product are of stainless steel and of borosilicate glass.

Detailed Operation & Maintenance Manual is provided along with the trainer.
