Freeze Spray Dryer for Water-Based Material

Penerangan

SD-18 mini spray dryer  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 .

SD-18 MINI SPRAY APPLICATIONS
SD-18 mini spray dryer can be used in a wide range of applications where the production of a free-flowing powder sample(10-120μm) 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.
 
SD-18 MINI SPRAY DRYER TECHNIQUE

1. A menu driven microprocessor controller allows the selection of inlet temperature, airflow, automatic de-blocker frequency and pump speed. The controller features an USB output for connection to a PC or datalogger and software allows the control and monitoring of all functions and printing of results(optional).
2. 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.
3. 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

1. 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.
2. air oilless compressor , the sound is low than 60db
3. Made of SUS-316 Stainless steel. Easy operating.
4. To assure accurate temperature control and easy parameter adjusting, YC-015 applies PID.
5. 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.
6. Narrow size distribution of particles.(10-100um)
7. Automatic de-blocking device prevents the nozzle from becoming blocked and variably controlled
