Points for Attention in the Use of Sweet Potato Starch Drying Equipment
The sweet potato starch kit consists of storage equipment and final dedusting equipment. In many areas, grain is harvested from the ground and sold to grain manufacturers. However, due to incomplete drying or drying, the finished products processed in the later stage, such as sweet potato starch, will affect the taste of food. Today, we will talk about how to use the dryer in the whole set of processing equipment of Kaifeng Sida sweet potato starch. Because of the drastic heating of materials during the operation of the dryer, if the operation is not proper or the pressure in the drying system rises sharply, explosion and other accidents may occur. Therefore, we suggest that in the process of using the small dryer, attention should be paid to fire and explosion prevention, and reducing oxygen content can prevent explosion. When designing the structure of the dryer, appropriate blasting holes should be set up and appropriate methods should be adopted to prevent fire and explosion.
When drying explosive materials, products should be avoided to stay in drying equipment or storage. For example, the hole on the top of the large spray dryer must clean the inner surface and avoid any material. It is cheaper to design some or all inert drying devices than to design combustion chambers with large drying equipment withstanding high internal pressure.
Then, in the selection and design stage, the noise limitation of the dryer should be considered. For the air suspension dryer, the fan is the main source of noise. In addition, pumps, gear boxes, compressors, spray devices, burners, agitators and so on all produce noise. In order to reduce fan noise, it is necessary to reduce the pressure drop in the device. To obtain a higher air intake effect, it is necessary to have a higher pressure drop, which is contradictory. The simple direct-fired dryer heated by air flow, especially by gas, can achieve the effect of low noise. But on the other hand, air reflux devices with multiple effects often need burners and auxiliary equipment, and their noise is high. )
