Spray dryers are used in the dairy industry

In the 1980s, a single-nozzle vertical pressure spray dryer was produced, and its application in the milk powder industry is a key link to promote the technological progress of China's milk powder industry, laying the foundation for the rapid development of China's milk powder industry. The milk powder produced by spray drying method is a uniform powdered product, no need to dry, cool powder, crushing and other processes, can be directly packaged as a finished product, so that the milk powder production process to achieve mechanization, continuity and large-scale, and because the surface temperature of the material will not be too high to improve the quality of milk powder products, so spray dryer in the milk powder industry has played a huge role, and there is a growing trend of drying moisture.
common types of dryers in contemporary China include spray dryers, air flow dryers, fluidized bed dryers, fluidized bed spray granulation dryers, mesh dryers and so on.
in China's dairy production, milk powder production accounts for about 80% of the total production of dairy products, because milk powder is easy to store and transport.
in the milk powder production process, the drying section is one of the important links in milk powder production, only the drying process to evaporate the amount of water is almost equivalent to the quality of the milk powder to be produced.
Generally speaking, the production process of the product determines the production equipment and control system of the product, the application of equipment and control system can also change the production process of the product, the application of spray dryer in the production of milk powder is a typical example.
spray dryer spray drying is one of the advanced equipment in drying equipment.
three conventional methods of atomization: rotational atomization, pressure atomization and airflow atomization.
type: rotating atomized spray drying is characterized by a large single-machine production capacity (spray volume up to 200t/h), the amount of feed is easy to control, the operating elasticity is large, the application is relatively wide.
: pressure negator spray drying is characterized by the manufacture particles, easy to repair.
because the nozzle hole is very small and easy to clog, the material must be strictly filtered.
nozzle holes are easy to wear and must be made of wear-resistant materials.
also has a new structure called a pressure-airflow nozzle.
its characteristics are the pressure nozzle, the surrounding environment gap is the air flow nozzle.
atomization is divided into two stages: the pressure nozzle first forms a liquid film, which is atomized by the air flow a second time, making the fog droplets thinner.
The advantages of this type of nozzle are: (1) adjust the pressure of compressed air, you can adjust the diameter of the droplets, the operation is simple;
: airflow atomizers are mainly used in laboratories and intermediate plants, and their power consumption is high.
the first two atomizers can not atomize the material, can use air flow atomizer atomization.
if the material is a high viscosity paste, paste and filter cake material, three fluid nozzles can be used to atomize.
air flow drying technology mature, if there is operational data, can be directly designed.
Shanghai Yuming Instrument Co. , Ltd. production of spray dryers have been sold in major cities in China, some have been exported to overseas markets, access to a good customer response, for a better tomorrow to draw a perfect end.
