SAKA employs highly advanced methodology of Computational Fluid Dynamics (CFD) analysis, to deliver guaranteed results for your Business, Process reliability and system performance. CFD simulation helps to foresee performance before actual execution of the systems, without actual installation of the system. It also helps understand the most vital parameters for improving performance.
TYPES OF SPRAY DRYER
Co-Current
Counter-Current
Mixed Flow
Nozzle Operation
Rotary Atomizer
Advanced drying System
CO-CURRENT SPRAY DRYER
Effective drying for heat sensitive material
In co-current spray dryers, feed and hot air are introduced in chamber to travel in same direction.
this type of drying process is ideal for heat sensitive material such as Dairy, Food or Fruit extracts as product does not suffer heat degradation.
Here feed comes in contact of warm air at its highest temperature. At the same time feed has very high moisture content. Moisture content of feed gradually gets reduced so does the temperature of the hot air leading controlled drying.
COUNTER CURRENT SPRAY DRYER
Rapid drying with higher thermal efficiency
In these type of Dryers, air and feed are introduced from opposite directions. Feed is introduced from the top and hot air is introduced from the bottom.Counter Current Dryers have better efficiency and output, but are not ideal for heat sensitive material. Typically, these type of Dryers are ideal for products like Soaps, Dyestuff, Detergents etc.
Here feed first comes in contact of warm at its lowest temperature and gradually gets exposed to the hotter air. Counter Current Dryers are more effective and have better thermal efficiency then that of a Co-current Spray Dryer.
MIXED FLOW SPRAY DRYER
Superior performance with better mixing process
This is a combination type of air flow system i.e. Counter as well as Co-current. Here Air is introduced from the top and atomizer is located at the bottom, thus providing mixed flow effect. This type of drying is slightly identical to counter current hence it is not applicable for heat sensitive material.
SPRAY DRYER WITH NOZZLE OPERATION
Uniform particle formation with effective drying
In case of Spray Dryer with Nozzle, Dryer comes with a spray nozzle which facilitates formation of fine droplets at very high speed. These kind of Dryers are used where faster evaporation of heat is required.
Here feed is introduced in drying chamber through a high pressure nozzles forming small droplets. These fine droplets get dried immediately as soon as they come in contact of hot air.
SPRAY DRYER WITH ROTARY ATOMIZER
Instant drying with high speed dispersion
Spray dryers with Rotary Disc Atomizers from SAKA are capable to handle material in large quantities and any viscosity. Wheel design is customized according to powder characteristics. Ideal for applications like herbal extracts, ceramics, inorganic chemicals and dye stuffs , these Spray Dryers are used where liquid feed is required to converted into fine droplets.
Feed is introduced through a high speed rotating disc which throws liquid outward at very high velocity. This leads formation of fine droplets which are dispersed on the walls of the spray dryer. these droplets when comes in the of hot air/gas to form dry solids, granulate or agglomerate particles
ADVANCED DRYING SYSTEM
Achieve the best efficiency with advanced drying system
Apart from Single Stage Spray Drying, SAKA also provides advanced double stage and multi stage drying solutions.
Double stage drying a combination of Spray Dryer and Fluid Bed or Vibrating Bed Dryer. Here moisture content after spray drying is relative higher as compared to single stage. After spray drying moisture content is further reduced in second stage where it passes through Fluid Bed Dryer or Vibrating Bed Dryer. Double stage drying enables drying at relatively lower temperature making it suitable for heat sensitive materials and also avoids its degradation.
