Necessary conditions to cause a dust explosion
Spray drying tech has a history of hundreds of years. It is a drying method that uses an atomizer to disperse the raw liquid into mist droplets. And the water vaporizes quickly after contact with hot air. Thereby it obtain powdery and granular products.
Spray drying tech was first used for egg processing in 1865. Since then, this process of directly turning a liquid into a solid powder in a short time through atomization and drying has made great progress. Now it has been widely used in food, chemical industry, medicine and other fields. While those include milk powder, soybean powder, coffee, medicine, etc.
There is a key atomization process in the spray drying system. The energy required for the spray drying nozzle is depend on the liquid supply pressure. The highest pressure required is several hundred kg. While the pressure mainly depends on the density, viscosity, solid content rate, wear and other properties. Ordinary hoses can not reach such high pressure. Hydraulic hose can fit such work. But it is not food grade. Thus it is not suitable for food use. Then how to do this work?
Here we Orientflex offer you the Teflon hose. Teflon hose is a kind of thermoplastic hose which adopts high quality PTFE as the raw material. Then there is a steel wire braid cover which protect the tube from cutting and impact. What’s more, we can offer you hose protection sleeve like spiral guard and silicone sleeve.
PTFE lined hose can work a wide range of temperature from -70℃ to 260℃. Besides, it has a high working pressure up to 35 Mpa. In addition, it is anti-UV and aging resistant. What’s more, it is food grade. Thus it is ideal for food use. Besides the R14 hose, we also offer you various fittings. Contact us now and get more details.
