Detailed description
product description:
High-speed centrifugal spray dryer is drying process liquid forming process and the most widely used in industry. Most suitable for the production of powder from suspension emulsions, solutions, emulsions and paste liquid, granular solid product. Thus, when the finished product particle size distribution, residual moisture content, bulk density and particle shape are in line with the precision standard, the spray dryer is ideal for drying process.
Highlights:
1, hot air and droplet contact: there is a sufficient amount of hot air into the spray-drying chamber, the hot gas flow direction must be considered and angle, and whether it is flow, countercurrent or mixed flow, to ensure full contact with the droplet can be sufficient heat exchange.
2, the atomization: atomized spray dryer system must ensure a uniform droplet size distribution, which is essential. Because in order to ensure that the passing rate of product quality.
3, and the angle of the cone angle of the pipeline design: We get some experience from the production data set nearly a spray station, and we can share.
Features:
1, spray drying speed when the material liquid is atomized, the surface area increased significantly, with the hot air in contact with the process, the moment can be 95% -98% moisture evaporation, drying time of just a few seconds, especially for heat-sensitive materials dry.
2, the product has a good uniformity, higher fluidity and solubility, purity and good quality.
3, spray dryer production process is simplified, easy to operate controls. For moisture content of 40-60% (for special materials, up to 90%) of the liquid can be dried into a powder product, after drying without crushing and screening to reduce the production processes, improve product purity. For the size, bulk density, moisture, within a certain range can be adjusted by changing the operating conditions, the control and management is very convenient.
Product Process Demo:
working principle:
Spray dryer for the open cycle and flow, centrifugal atomization. After air drying medium early, medium efficiency air filters and filtered according to the operating instructions drawn by the blower and then heated by the heater into the spray-drying tower through the main HEPA filters hot air distributor. After the liquid material in accordance with an operation instruction peristaltic pump, atomizer into the high-speed rotation, the centrifugal force is dispersed into small droplets. In the primary spray drying tower, hot air with small droplets in full contact drying by heat exchange with a product along a particular path, then through a cyclone to achieve separation, the solid material is collected, filtered and then the gaseous medium, and then discharged . Spray the entire system easy to clean, no dead ends, in line with GMP requirements.
Applications:
Chemical products: PAC, disperse dyes, reactive dyes, organic catalysts, silica, washing powder, zinc sulfate, silica, sodium silicate, potassium fluoride, calcium carbonate, potassium sulfate, inorganic catalysts, each and other kinds of waste.
Food: amino acids, vitamins, eggs, flour, bone meal, spices, protein, milk powder, blood meal, soy flour, coffee, tea, glucose, potassium sorbate, pectin, flavors and fragrances, vegetable juice, yeast, starch, etc.
Ceramics: Alumina, zirconia, magnesia, titania, titanium, magnesium, kaolin, clay, various ferrites and metal oxides
