LabPlant SD-06A Spray Dryer


For use specifically with aqueous based solutions.

The LabPlant SD-06A Laboratory Scale Spray Dryer is the result of 30 years of continuous development in the field of laboratory scale spray drying systems.

The unit is self contained and supplied complete and ready for immediate operation. All major components are housed within a stainless steel cabinet and the unit can be used on a bench top or with an optional stainless steel stand.

The SD-06A only requires connection to a 13 amp, 220/240 V, 50 Hz power supply (Other Power Requirements Available) and provision for exhausting the evaporated moisture to atmosphere or to an existing extraction system.

TECHNIQUE

A menu driven microprocessor controller allows the selection of inlet temperature, airflow, automatic de-blocker frequency and pump speed. The controller features an RS 232 output for connection to a PC or datalogger and software allows the control and monitoring of all functions and printing of results.

The self-priming peristaltic pump delivers the sample liquid from a container through a small diameter jet into the main chamber. At the same time an integral compressor pumps air into the outer tube of the jet which causes the liquid to emerge as a fine atomised spray into the drying chamber.

Heated air is blown through the main chamber evaporating the liquid content of the atomised spray. The solid particles of the material, which are normally in a free flowing state, are then separated from the exhaust air flow by a cyclone and collected in the sample collection bottle. The exhaust airflow is directed through a flexible 50 mm diameter hose direct to atmosphere or to an existing extraction system.

APPLICATIONS

Spray drying can be used in a wide range of applications where the production of a free-flowing powder sample is required. This technique has successfully processed materials in the following areas:

  Beverages
  Flavours and Colourings
  Milk and Egg Products
  Plant and Vegetable Extracts
  Pharmaceuticals
  Heat Sensitive Materials
  Plastics
  Polymers and Resins
  Perfumes
  Ceramics and Advanced Materials
  Blood
  Dyestuffs
  Foodstuffs
  Adhesives
  Oxides
  Bones, Teeth and Tooth Amalgam and many others.

Most solutions and suspensions can be spray dried providing that the resulting product has the characteristics of a solid material.

CONSTRUCTION

A robust chemically resistant 316 grade stainless steel cabinet houses all mechanical and electrical components necessary to perform the spray drying process. All clamps and fittings are designed to allow assembly and removal of the glass components in only a matter of seconds.

The rear of the cabinet includes an inlet filter designed to remove 99.99% of air laden particles ensuring that the drying air does not include contaminants. A specially designed stainless steel support stand is available where bench space or height restrictions are a consideration.

TWO FLUID NOZZLE

The stainless steel spray assembly consists of an inner tube for the liquid sample leading to a small diameter jet. An outer tube directs the supply of compressed air to the nozzle and the close tolerance gap between the nozzle and the jet ensures a fine vaporised spray. The SD-06A is supplied as standard with 0.5 mm jet and other sizes are available as accessories.

The spray assembly incorporates an automatic de-blocking device that prevents the jet nozzle from becoming blocked. The de-blocking needle is activated by an integral compressor.

De-blocking is sometimes necessary with materials which may solidify or when large particles in suspension cause blockages in the jet.

CONTROLS AND FUNCTIONALITY

The unit is designed to ensure that all functions are simple to select and adjust, to quickly achieve the optimum conditions for Spray Drying.

Using a clear LCD display, which is protected to IP65, the operator can control the following functions:

  Inlet temperature
  Airflow volume
  Pump speed
  De-blocker frequency
