Lab Inert Loop Spray dryer for organic solvents, 1500ml/h

SPD-15A Inert Loop Spray Dryer 

SPD-15A Lab inert loop spray dryer with inert loop system for organic solvent, 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 system was designed to be stand by a keyboard, conducted by a colorful crystal screen of touch guidance mode , and allowed two modes of run: Automatic-mode, and Eye-monitored mode for the purpose of easily controlling experimental process .

PRINCIPLE

• 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 data logger 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 60 mm diameter hose direct to atmosphere or to an existing extraction system.

ADVANTAGES

• Two modes of run: Automatic-mode, and Eye-monitored mode for the purpose of easily controlling experimental process . PLC controller, LCD touch panel control fascia with flow path of system. Using proface touchable interface display operation, operator can control temperature, airflow volume, air pressure, pump speed and de-blocker frequency.
• Spray chamber, cyclone separator, receiving tank are all made of Borosilicate glass which can resist strong acid/alk li, high temperature. It can work in a no-pollution and stable environment, and the whole process can be inspected. All the spare parts are easy to install and wash.
• Made of SUS-316 Stainless steel. Easy operating.
• To assure accurate temperature control and easy parameter adjusting, SPD-15 applies PID.
• A filter has been equipped to the inlet unit to prevent the sample from contamination .
• The self-priming peristaltic pump delivers the sample liquid from a container through a small diameter jet into the main chamber to avoid secondary pollution.. To make sure the process conducted steady and smoothly, magnetic agitator is optional to make the solution well mixed.
• Narrow size distribution of particles.
• Automatic de-blocking device prevents the nozzle fro m becoming blocked and variably controlled
• The air compressor is no oil and don’t pollute compress air. The power from receiving tank has a good flow. The sound is low than 60db, and following the GMP understands.
• Supplied complete and ready for most spray drying applications.
• Automatic de-blocking device prevents the nozzle from becoming blocked and variably controlled.
• Equipped with air filter to remove and collect fine particle s in exhausted air.
• Can be used for organic & water solvents (Model SPD-15A)

TECHNIACL INFORMATION

MAIN COMPONENTS

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 •

Soaps and Detergents • Blood • Dyestuffs • Foodstuffs • Adhesives • Oxides • Textiles • 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.
