Centrifugal High Speed Spray Drying Machine Description:
Centrifugal High Speed Spray Drying Machine is the technology most widely used in the liquid technology shaping and in the drying industry.The drying technology is most suitable for producing solid powder or particle products from liquid materials,such as: solution, emulsion, suspension and pumpable paste states,For 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 technologies.
Spray drying is the most widely used industrial process for particle formation and drying. It is well suited for a continuous production of dry solids in powder or agglomerated particles form from a liquid feedstock. The feedstock can include solutions, emulsions, and pumpable suspensions. The technology is ideal when the end-product must comply with precise quality standards such as particle size distribution, residual moisture content, bulk density and particle morphology.
During spray drying, an enormous heat and mass transfer takes place within a fraction of time. It starts with the atomization of a liquid feedstock into a spray of droplets (1 liter of concentrate is atomized to 1,5 x 1010 droplets with a diameter of 50 microns with a total surface of 120 m2 and the evaporation takes place from the surface of all these particles). The small droplets are created by an atomizer - either a rotary wheel or a high pressure nozzle. The droplets are introduced into a hot airstream, which is cooled down due to the evaporation of the water or a chemical solvent from the concentrate. This now colder and humid air is discharged from the dryer through a cyclone, bag filter or a combination of the two. After separation of the now dry particles, the air is discharged into the atmosphere. The dry particles can be cooled and bagged off after separation from the process air.
High Speed Spray Drying Machine Principle:
High Speed Spray Drying Machinery Features:
● The drying speed is high when the material liquid is atomized,the surface area of the material will increase greatly.In the hot-air flow,95%-98% of water can be evaporated at a moment.The time of completing the drying is only several seconds. This is especially suitable for drying the heat sensitive materials.
● Its final products own the good uniformity, flow ability & solubility. And the final products are high in purity and good in quality.
● The producition procedures are simple and the operation and control are easy.The liquid with moisture contents of 40-60%(for special materials,the contents might be up to 90%).can be dried into the powder or particle products once a time. After the drying process, there is no need for smashing and sorting,so as to reduce the operation procedures in the production and to enhance the product purity.The product particle diameters,looseness and water contents can be adjusted through changing the operation condition within a certain range. It is very convenient to carry out control and managment.
