Corn Starch centrifugal spray dryer

 

Simple Instruction

 

The spray drying is the technology most widely used in the liquid technology shaping and in the drying industry. The drying technology is the most suitable for producing solid powder or particle products from liquid materials, such as: solvent, emulsion, suspension and pumpable Paste states, fro this reason, when the particle size and distribution of the final products, residual water contents. Mass density and the particle shape must meet the precise standard, spray drying is one of the most desired technology.

 

Working Principle

 

Hot air is distributed downwards with spiral method into the drying tower after filtering and heating. Meanwhile, solution is nebulized millions of single granule and form fog drop. Then the fog drop contact with the hot air and most of the water flash immediately to form the dry product. These powder and granule fall into the air exhaust pipe at the bottom of the drying tower, collected in the material tank.

 

Feature

 

Rapid drying speed, which just takes 5-15 seconds.

Suitable for thermo-sensitive material and keep the origin state.

Simple processing and easy operation, which is suitable for continuous production.

The product has a good degree of uniformity, liquidity and dissolubility with high quality and purity.

Can adjust the product diameter, density and water content in some degree which is convenient to control and manage.

 

Spray Drying Machine working Steps

 

1. Atomizing:Atomize raw material into uniform fog drop through atomizer

2. Contact between fog drop and hot air: The hot air enters to the drying station to contact with fog drop through air distributor, and make a certain movement in drying station. (the movement can be co-current flow, adverse current or mixed flow)

3. Drying Process: Fog drop has big surface area, and appears obvious grades to hot air both in temperature and humidity, thus strengthn the transmission process of plastid caloric, moisture of fog drop is evaporated very quickly (within seconds to tens of seconds)

 

Important Tech

 

Atomization: Atomizing System must ensure the spray drop distributing uniformly.

The contacts of hot airflow and spray drop: when enough hot air enters into drying tower, the flow way and angle have to be considered, no matter co-current flow, adverse current or mixed flow, must ensure the sufficient heat exchange, it is crucial.

The angle design of the connection pipes and cones: it is very important to select the suitable angle, here we would like to share our experience from production of thousands of this equipments.
