Potato residue dryer

Potato starch is made from potatoes, including the skin, which are cooked, dried and finely ground. It can be used as a thickener, but in some baked goods, it can retain moisture. The potato starch production process is basically the same as the starch production process of fresh sweet potatoes, but industrial potato starch production is simpler than manual production. It is mainly organized by the processes of washing, grinding, screening, protein separation, cleaning, dehydration and drying of raw materials.

Working principle of potato residue dryer
The wet potato material is densely arranged with wedge-shaped hollow blades on the hollow shaft, and the heat medium flows from the hollow shaft to the blades. The heat transfer area per unit effective volume is large. The temperature of the heat medium ranges from -40℃ to 320℃, which can be water or other liquids, such as hot water, heat transfer oil, etc. Indirect conduction heating does not carry air to take away heat, and the heat is used to heat the material. The heat loss is only the heat dissipation to the environment through the insulation layer of the device body. The wedge-shaped blade heat transfer surface has a cleaning function. The relative movement between the material particles and the wedge surface produces a scrubbing effect, which can scrub away the material attached to the wedge surface so that the heat transfer surface is always kept clean during operation. The shell of the paddle dryer is a type, and two to four hollow stirring shafts are generally arranged in the shell. The shell has a sealed end cover and an upper cover to fully play a role in preventing the leakage of material dust. The heat transfer medium flows through the shell jacket and the hollow stirring shaft through the rotary joint. The hollow stirring shaft has different internal structures according to the type of heat medium to ensure the heat transfer effect.
