The dryer can ensure the natural color of the sweet potato so that the dried sweet potato is not easily deformed, and the nutrients are not lost. The dryer has a high degree of automation and does not require human supervision. The drying process is all controlled by a microcomputer, and the operation is convenient. Next, I will share with you the specific steps of making dried sweet potatoes.

How to dry sweet potatoes in the sun:

• 1. Material selection: Choose large sweet potatoes with thin skins and low starch content.
• 2. Clean and steam: Wash the sweet potatoes, cut them in half, and steam them in boiling water.

How to dry sweet potatoes in an oven:

• 1. Rinse the sweet potatoes in water, steam them in a steamer, or boil them directly in water. In this case, the moisture will be more and the roasting time will be longer.
• 2. After the steamed sweet potato is cooled, peel off the skin of the sweet potato and cut it into small strips of uniform thickness and the same length.
• 3. Put the sweet potato strips evenly on the grilling net.
• 4. The oven temperature is set to 100°C for 60 minutes, and it can be taken out and turned over during the drying process

Tips:

  The thinner the sweet potato strips are cut, the shorter the baking time, but it should not be too thin.

How to use the dryer to mass produce dried sweet potatoes:

• 4. Drying: Put the sweet potato chips into the oven when the temperature of the oven rises to about 30°C.  Set the temperature to 40°C. The drying time is 1-2 hours.The temperature is set to 55°C, the continuous dehumidification mode, and the drying time is 2 hours.The temperature is set to 65°C, the continuous dehumidification mode, and the drying time is 2 hours.The temperature is set to 70°C, and the drying time is 1 hour.
• 5.Turn off the power, take out the dried sweet potato after one hour, vacuum package the dried sweet potato after cooling, and store it in a cool environment or refrigerate it.

Precautions:

  Pay attention to temperature control during the drying process of sweet potatoes. 

  If you need to process a lot of dried sweet potatoes, Baixin Machinery’s drying equipment is a good choice. Baixin Machinery is a manufacturer specializing in the production of dryers. It has 20 years of rich experience. For sweet potatoes drying, it has professional drying equipment and mature drying technology to ensure the perfect drying effect.

  Baixin Machinery’s most popular sweet potato dryers are heat pump dryers and continuous mesh belt dryers.I would be happy to introduce these two dryers in detail for you:

1:The first method:sweet potato heat pump dryer

Household Commercial All-in-one drying equipment without installation for any material
  Drying essence is take moisture away, but takes away the moisture temperature is not the most critical factor. The key for drying is depending on relative humidity within certain space, Baixin Company took advantage of the dry essence, originality developed a "Closed Cycle" dryer, changed the traditional heat pump dryer "bake" to "dehumidifier”. Its several advantages were unmatched by the traditional heat pump dryer.
  Baixin Food Dehydrator has a compact structure, great energy-saving, wide application, high drying quality, easy operation, simple installation and removable. it is the best drying equipment for small firms, drying experiment and scientific research. The users only connect the power to use, is the easiest operation heat pump dryer.

2:The second method: sweet potato continuous mesh belt drying machine

Large amount of dehydration 200-5000kg/h sweet potatoes drying machine continuous automatic work easy operation
  Sweet potato dryer machine is a kind of continuous production drying equipment, the main heating way has electric heating, steam heating, hot air heating. Its main working principle is to spread the material evenly in the network. The material is moved in the dryer by the operation of the machine, and the hot air draws out the water vapor of the material. so as to achieve the purpose of drying.
  The operation temperature is 40-120 degree centigrade. And the dry cycle is 1-5 hours.
