• Incorporates integral set de-blocking device.
• Product flow rate: 0-1500ml/hr
• Air inlet temperature: 200°C max.
• Heater capacity: 3kW
• Drying air throughflow: 70m3/hr (fixed).
Description
The all glass construction and design of the spray assembly minimises any possible contamination and will produce a free flowing, near spherical powder. In the spray drying process the product is introduced in liquid form and emerges as a dry, fine powder. Thermal shock is minimal.
The process may be used for Powder Coating (agglomeration) where the fine product is adhered together into small balls with the aid of filmogen. Other processes where spray drying is found to be successful are Micro Encapsulation and Englobulation.
The spray drier can be used for the following applications in the food industry:
- beveragesfish extracts
- fish extractsheat sensitive materials
- heat sensitive materialsmilk and egg products
- milk and egg product
- scereals
- plant and vegetable extracts
A fine jet of the liquid to be dried is brought into contact with a hot air stream. This evaporates the spray moisture and carries the solid particles into the cyclone separator. The solids are collected in a sample jar at the base of the cyclone and the exhaust vapour is directed to the outside atmosphere, or fume/dust extractor.
