Laboratory Scale Spray Dryer

Laboratory Scale Spray Dryer - ESDTi spray dryer

A cost effective solution for entry level Spray Drying with all the features required for the testing and development of powders within the laboratory.

This compact laboratory spray dryer has a maximum temperature of 200°C and liquid flow rate up to 1.6kg/hr. The unit is ideal for R&D and sample preparation of many products. The unit incorporates all parts necessary for the spray drying process and allows control of inlet temperature, liquid sample flow, drying airflow and compressor pressure. Incorporating an integral compressor, the spray dryer remains extremely compact requiring less than 0.2msq bench space.

The ESDTi 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 onto the unit, which is easily dismantled for cleaning.

FEATURES • Two fluid nozzle • PID automatic control • CALgrafix Process Monitoring Software • Integral Compressor • Mobile design

BENEFITS • Ease of cleaning • Robust design • Wide range of operating parameters • Electrical heating • Simple service connections • ‘Plug and Play’

Applications and Software

The most successful drying applications for spray dryers are for solutions, slurries and pastes which:
  • cannot be dewatered mechanically
  • are heat sensitive and cannot be exposed to high temperatures for long periods or
  • contain ultrafine particles that will agglomerate and fuse if dried in any state other than a dilution.
Spray drying is especially applicable to heat sensitive products due to the exceptionally short residence time in the dryer hot zone. Pharmaceuticals, foodstuffs, pigments and dyes, detergents, urea and plasma are all examples of products that have been successfully spray dried.CALgrafix Process Monitoring Software – supplied as standard. CALgrafix is designed for applications where there is a requirement to monitor and record temperature data. A real time graphic presentation displays the temperature profile of your process. CALgrafix features logging, charting, alarm indication, networking and configuration within a simple WindowsTM based user interface. Advantages of using CALgrafix :
  • Access to detailed process data via the charting and logging features
  • Simple set-up, no programming skills required
  • Export logged data to other applications
