Starch drying process
[summary of air drying]
Air drying is also called &ldquo, and &rdquo is dry in an instant; it is the application of thin phase transport in solid fluidization in the field of drying. The method is to directly contact the hot air and the solid particles to be dried, and to dry the solid particles (starch) suspended in the fluid. Therefore, the two phase contact area is large, which strengthens the heat and mass transfer process. The airflow is applied to the drying unit operation of bulk materials.
[characteristics of air drying]
The air drying unit of Liangshan machinery factory, fully consider the factors of turbulence flow, cyclone separation and heat exchange, the high-efficiency heat exchanger, digital temperature detection and stepless variable speed fan to adjust temperature and other advanced technology equipment, has the following characteristics:
1, the whole system adopts automatic control. By adjusting the moisture and temperature difference of the feed, the feed volume and intake volume can be automatically adjusted, so as to ensure the moisture stability of the product.
2, the heat efficiency is high, the drying time is short, the amount of treatment is large, the gas - solid two - phase flow operation is adopted in the air drying.
3. The variable diameter turbulence technology is used to improve the performance of the equipment and ensure the quality of the starch.
4. The air dryer is simple in structure, compact, small in volume, large in production capacity and low in cost of investment and maintenance.
5. The operation is convenient. In the air drying system, the unit process, such as drying, crushing, sieving and transporting, is combined.
6, a wide range of applications, can be suitable for all kinds of powder, flaky, material like material.
[the scope of application of air drying]
1. material state, air drying requirement is mainly powder or granular material, its particle size is generally below 0.5mm-0.7mm, at most not more than 1mm;
2. the combined state of moisture content and material, the air drying adopts high temperature and high speed gas as the drying medium, and the contact time between the gas and solid two phase is very short.
3. the equipment is widely used for the drying of granular materials such as starch and grain.
