Dryer equipment is also playing an increasingly important role in the industry. Air energy high-temperature heat pump dryer This new type of drying, which saves money, energy-saving and high-efficiency, and good dry quality, welcomes better development opportunities with the spring breeze of energy-saving emission reduction and energy structure innovation development.

The conventional drying device directly uses electric heating or fuel combustion to obtain the heat required for drying, has large energy consumption and large pollution, and the air energy heat pump drying is a high-efficiency heating device (output heat energy > heat consumption), as a new technology. The heat pump drying system is a dehumidifying drying device that does not use electric heating wire heating or other heat source radiation heating. It has the advantages of energy saving, environmental protection and safety, and has obvious advantages in energy consumption and drying cost.

Sweet potato is rich in protein, starch, pectin, cellulose, amino acids, vitamins and various minerals. It has the reputation of “longevity food”. It has anti-cancer, protects the heart, prevents emphysema, diabetes, and lose weight. It is known as longevity food in Japan and has good medicinal effects.


Ancient literature such as "Compendium of Compendium of Materia Medica" records that sweet potato has the effect of "reinforcing deficiency, benefiting Qi, strengthening spleen and stomach, strengthening kidney yin", making people "longevity and less illness". Can also make up, and blood, warm stomach, fat and five internal organs. The contemporary "Chinese Materia Medica" says: "Sweet, flat, spleen, kidney." The high-temperature heat pump dryer produced can achieve very good drying effect, and the operation is very convenient and easy, greatly reducing Labor intensity saves labor costs. It is clean and environmentally friendly during use, does not cause environmental pollution, and can effectively control drying time and temperature. The drying quality is very stable and is very popular among users. It has been popular in many places in the south, and it is widely used. Used in the production of sweet potato drying.

Sweet potato drying steps:

First, preliminary work

The sweet potatoes are first cleaned and then placed in a boiler for cooking. Take it out when the sweet potato is about seven or eight mature, and then manually slice it after cooling.

In the sectioning process, the thickness must be consistent first, and secondly, try not to let the specifications of the sweet potato chips differ too much.

After these processes are completed, the cut red sweet potato strips are placed on a shelf on which the materials are placed. Make the thickness uniform and neatly placed

Second, the drying process

1. Put the sweet potato chips into the interior of the drying room when the temperature of the drying room rises to about 30 °C. The set temperature is 40 °C. The drying time is one to two hours.

2. The temperature is set to 55 °C. The drying time is two hours.

3. The temperature is set to 65 °C. The drying time is two hours.

4. The temperature is set to 70 °C. The drying time is one hour.

5. Turn off the power and take out the material after one hour.

Third, packaging into the bag

After the material is taken out, the sweet potato chips are completely cooled before they can be packed into the bag. Overall, the drying time for a batch is approximately 8 hours and the maximum temperature does not exceed 70 °C.
