Industrial Milk / Milk Powder Spray Dryer Machine

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.
Features
Introduction The pressure spray drying machine is widely used in liquid process industry.Machine body, pipe, separator of set where connect with the raw material are made of SUS304.Line noise, balanced running, controlled temperature, easy installation are fruit dryer's features.Using forced ventilation, equiping with adjustable air divider plate, uniform drying. Heat source can be steam, hot water, electricity.Easy to operationExcellent after-sales service
Character1). The dry speed is fast and suitable for drying thermal sensitivity material particularly.2). According to the characteristics of raw material, it can use hot air to dry or cool air to franulate.3). The evaported amount is related to characteristics of raw material.
Working Steps1. Atomizing: Atomize raw material into uniform fog drop through atomizer2. 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.
Wide Range of Use
According to the characteristics of material , Both hot air drying and cold air condensed solid droplets two methods can be adopted, a large number of products with very different physical properties can use this device to perform production. commonly used with the following types of polymers and resins, dyes, colors, color materials, ceramics, glass, rust remover, fungicides, insecticides, carbohydrates, dairy and egg products category, tannins, slaughterhouse by-products, blood and fish products, detergents and surfactants category, type of fertilizer, organic compounds and inorganic compounds.
