Spray Dryers is the perfect Choice for Heat Goods


Spray drying gear is considered the most widely utilized industrial process involving particle formation and drying. It truly is highly suited for your ongoing manufacturing of dry solids in possibly powder, granulate or agglomerate type from liquid feedstocks as options, emulsions and pumpable suspensions. Spray drying is definitely an ideal procedure wherever the end-product must stick to specific high quality specifications with regards to particle measurement distribution, residual dampness material, bulk density and particle shape.
A spray dryer separates the solute as a solid and the solvent as a vapour and the solid is easily collected in a drum. The liquid is sprayed through a nozzle into a hot vapour stream and gets evaporated. The spray drying process is a continuous operation in which the liquid is converted into a free flowing powder very quickly.
Spray Dryers are available in a range of sizes and these ensure uniform quality, moisture content and particle size distribution. It ensures a good performance at easy rates and can be customized to suit the individual requirements.
Industrial Spray Dryers that can handle tons of raw materials are in use in various industries like pharmaceutical, polymer, ceramics and food among others. There are various types of spray dryers including industrial flash dryers, spray dryers, flash dryer etc to suit the various needs of the customers.
recently ultrasonic energy has been used in place of pressure or centrifugal force to form droplets. In this method, a liquid is placed on a rapidly vibrating surface at ultrasonic frequencies. At sufficiently high amplitude, the liquid spreads, becomes unstable and collapses, resulting in the formation of very fine droplets. These devices are excellent for droplets below 50 microns. Their use is expected to grow over the next few years.

The spray drying technique is extensively used in the manufacture of dry powdered substances like milk powder and instant drink mixes among others. Thermal degradation of products can be avoided by operating the spray dryers at a lower temperature and using larger chamber sizes for increased residence times. The latest innovations have resulted in qualitatively superior spray dryers that can retain the aroma and texture ofthe products even at high temperatures.
Industrial spray dryers are available in various capacities and energy consumptions. A strong and stable design and flow stability is crucial for the longevity any spray dryer. Unsteady flow of residue particles might result in getting the residue deposited to the inner walls, which could catch fire due to overheating in products like milk powder or chemicals.The production of particles from the process of spraying has gained much attention in recent years. These efforts have resulted in spray technology being applied to the manufacture of particles to generate products ranging from pharmaceutical direct compression excipients and / or granulations to microencapsulated flavors.
