Heat pump heating unit. 2. Insulation box device. 3. Hot air circulation device. 4. Automatic moisture removal device. 5. Intelligent control device. The entire system of the main drying oven adopts SUS304 stainless steel inner plate design. The entire box is equipped with a 30MM thick polyurethane insulation layer, which has good thermal conductivity. The patented air distribution system independently designed and developed ensures uniform air speed and heat distribution in the drying room, and there are no dead corners when drying at 360 ℃. The material quickly dries without mold, reducing the drying time. Completely closed loop, completely recovering heat, achieving zero heat loss during the drying process, improving energy utilization efficiency, which is also 33% higher than the industry average level

The lychee king variety from Hainan grows in the volcanic ash terrain zone, with unique soil and geological environment. Its fruits are the size of eggs, abundant in water, and have a large output, making it a new favorite in the market. Litchi ripens and does not wait for others.

The use of a lychee dryer, with multiple moisture regain and back drying, is one of the key factors in improving the quality of lychee drying. Lychee with peel drying, the initial drying temperature is controlled at 65-70 ℃ (based on the degree of hot shell), and the drying is stopped after 24 hours. The temperature for re drying is controlled at 55-65 ℃, and the completion of the drying process takes approximately 28-32 hours. The drying temperature of the peeled fruit pulp is around 50 ℃. With the intelligent temperature and humidity control system set up, the equipment automatically dries, completing a batch of drying in about 15-20 hours. Depending on the production capacity, each batch can be baked from 600 to 800 kilograms, 1000 kilograms, and 2000 kilograms.
