RDYLPW series pressure spray dryer is a device that can complete drying and granulation at the same time. According to the process requirements, the pressure, flow and nozzle size of the feed pump can be adjusted to obtain the required spherical particles with a certain size ratio.
The feed liquid is input under high pressure through a diaphragm pump, spraying mist like droplets, and then flowing down in parallel with hot air. Most of the powder particles are collected by the bottom discharge port of the tower, and the exhaust gas and its small powder are separated by a cyclone separator. The exhaust gas is discharged by a fan, and the powder is collected by a pollination tube located at the lower end of the cyclone separator. The fan outlet can also be equipped with a secondary dust removal device, with a recovery rate of over 96-98%.
1. The drying speed is fast, and the surface area of the material liquid is greatly increased after atomization. In the hot air flow, 95% -98% of the water can be evaporated in an instant, and the drying time only needs tens of seconds to tens of seconds. It is particularly suitable for drying heat sensitive materials.
2. All products are spherical particles with uniform particle size, good flowability, good solubility, high product purity, and good quality.
3. Widely applicable, according to the characteristics of the material, it can be dried with hot air or granulated with cold air, with strong adaptability to the material.
4. Simple and stable operation, convenient control, and easy implementation of automated tasks.
Note:
1.The amount of water evaporation is related to the characteristics of the material and the evaporation temperature. In this table, the calculation is based on the inlet air temperature of 150-160 ℃.
2. Users can choose drying methods such as co current, co current, and powder return to achieve the desired product effect.
3. The process diagram is only for illustration purposes, please select the components according to your needs.
Food, medicine, chemical industry, dyeing and chemical industry, ceramics, biochemistry, pesticides, plastics, etc. are suitable for spray drying granulation of liquid with corresponding fluidity.
