Spray Dryer for Maltodextrin Test

PRINCIPLE

1.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.  

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. Using proface touchable interface display operation, operator can control temperature, airflow volume, air pressure,pump speed and de-blocker frequency.

2.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.

3.Made of SUS-316 Stainless steel. Easy operating.

4.To assure accurate temperature control and easy parameter adjusting, YC-015 applies PID.

5.A filter has been equipped to the inlet unit to prevent the sample from contamination .

6.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.

7.Narrow size distribution of particles.

8.Automatic de-blocking device prevents the nozzle from becoming blocked and variably controlled.

9.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.

10.Supplied complete and ready for most spray drying applications.

11.Automatic de-blocking device prevents the nozzle from becoming blocked and variably controlled.

12.    Equipped with air filter to remove and collect fine particle s in exhausted air.

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.
