Features Of Laboratory Spray Dryers:
- Sturdy construction
- Excellent resistance aganist corrosion
- Reliable performance
- Optimum strength
Principle Of Laboratory Spray Dryers:
Peristaltic pump of dryers is using for delivering liquid from one container to 2 fluid nozzle mounted on drying chambers. Compressed air from compressor is supplied to nozzle, which results in atomization of fluid into a fine spray. Air in the blower gets heated with the help of an electrical air heater which blows through drying chamber. Drying is very fast because of large surface area which decreases temperature. In cyclone separator, dry powder particles gets separated from which gets collected in glass collection bottle. And, the exhausted air is released through a flexible SS hose into the atmosphere. In addition to this, a bag filter is also provided for secondary powder collection as per the requirement of clients.
Construction Of Laboratory Spray Dryers:
- Blower, air compressor, pump and electrical air heater are placed in a panel made of stainless steel which is easy access.
- A fine cloth filter is used for filtering air entering the panel
- Chambers and cyclones are made up of borosilicate glass fitted with clamp fillings
- Dryer is very easy to assembly and remove.
Controls Of Laboratory Spray Dryers:
These dryers are easy to operate fitted with inlet air temperature which is precisely controlled by the inlet temperature PID controller.
- Inlet Temperature controller.
- Outlet Temperature indicator
- On/Off switch and indicator for feed pump
- Pump speed control with LCD display
