Introduction to sweet potato vermicelli：

  The sweet potato vermicelli is not bad after cooking for a long time. It is fragrant and delicious, and has various ways of eating. It is a kind of food material made by using sweet potatoes as raw materials and relying on the starch in sweet potatoes. Sweet potato vermicelli can be cooked in a variety of ways to make a variety of dishes.

Sweet potato vermicelli processing steps：

  The vermicelli is first processed into powder and then into noodles. First, the sweet potatoes are washed and peeled, cut into small pieces and beaten with a machine. The water and starch in the pulp are filtered and separated to obtain pure sweet potato flour for later use. Add sweet potato starch to warm water and mix it evenly with a machine to form a dough.
Squeeze the sweet potato vermicelli, the sweet potato dough is squeezed by the machine and transformed into a uniform thickness of sweet potato vermicelli. The sweet potato vermicelli must be put in a cold water bath first, and then drained from a bamboo pole into the freezer for finalization (the traditional process is to freeze it overnight).

Sweet potato vermicelli drying process：

  The vermicelli after the overnight cold storage has frozen into ice cubes on the outside. At this time, it is pushed into the sweet potato vermicelli drying room for heating and dehumidifying drying. After the water in the sweet potato vermicelli melts and evaporates, the roots begin to harden. The sweet potato vermicelli dryer sets the drying system parameters through the intelligent temperature and humidity control system to quickly improve the drying time and the quality and appearance of the dried sweet potato vermicelli. After the sweet potato flour is fully dried and evenly cooled to room temperature, it is bundled into the warehouse for packaging and storage.

Precautions:
Teach you a way to judge whether the sweet potato vermicelli is authentic. From the outside, the authentic sweet potato vermicelli is slightly rough and darker in color. It can also be burned. After the sweet potato powder is ignited with a lighter, it is authentic if it is accompanied by the fragrance of grains. If it has a plastic taste, it indicates that it contains additives such as gelatin. .

Recommendation of sweet potato vermicelli dryer/drying machine

Commercial 100-3000kg/h large amount of dehydration wide application and easy operation

  Heat pump drying machine use the principle of inverse Carnot cycle. It absorbs low-temperature heat energy in the air, which becomes high-temperature heat energy after efficient heat collection and integration by the heat pump system, and is transported to the drying room for cyclic heating and drying of materials.It refers to exhausting the hot and humid air in the drying room directly to the outside of the drying room through dehumidification device, and then replenishing natural fresh air.

  Hot air circle drying machine belongs to high temperature heat pump unit. Its working principle is: the working fluid of the heat pump is compressed by the compressor, becomes high temperature and high pressure gas, enters the condenser, condenses and liquefies the heat, and is used for air heating in the drying room. The moisture in the material is vaporized and evaporated by the form of hot air, and the evaporated water vapor is discharged by the moisture discharge system, thereby achieving the purpose of drying the drying material.
