The gradual expansion of the heat pump drying market and the expansion of application fields, it has played an important role in promoting rural economic development and increasing farmers’ income. In addition, the government has vigorously promoted poverty alleviation in rural areas in recent years, which has also brought huge development opportunities for heat pump drying.
Ningxia has always been the main producing area of goji berries. Goji berries have been cultivated in Ningxia for four to five hundred years. The temperature difference between day and night in Ningxia is large, the air is fresh, and the soil is fertile, which is suitable for the growth and planting of goji berries. Ningxia is the origin of goji berries, the best and longest-growing place in the world. The quality of Ningxia wolfberry benefits from the unique geographical and climatic conditions in Ningxia, and its quality is far superior to those produced in other regions. Ningxia wolfberry is rich in 18 kinds of amino acids, more than 30 kinds of trace elements, and a variety of biologically active alkalis, among which the content of β-carotene, vitamin E, and wolfberry polysaccharide is 10% to 70% higher than that of wolfberry from other places.
Due to the large annual output and concentrated harvesting time, drying has become a difficult problem for growers. The traditional drying method is natural drying, but it will bring secondary pollution and be affected by the weather. The drying temperature of coal-fired hot air stoves is not good. Control, poor quality after drying. Heat pump drying has many advantages such as safety, environmental protection, energy saving, and sanitation, and has gradually been favored by the market. Recently, Aubert built a heat pump drying room for the wolfberry plantation in Ningxia, making full preparations for the wolfberry harvest in the second half of the year. According to Mr. Peng, the person in charge of the project, a total of 30 15P heat pump dryers were equipped.
Shuntec Machinery is a green new energy enterprise focusing on the research and development, production, sales, and after-sales of heat pump drying products, and providing comprehensive drying and dehumidification solutions. It has a complete industrial chain of heat pump dryer products. At present, Shuntec Machinery has successfully applied in 38 drying categories, accumulated 100 engineering cases, precipitated 72 industry drying technology experiences, and has 5 core technology patents, covering 85 ℃ high-temperature heat pump dryer, -10 ℃Ultra-low temperature dryers, split dryers, integral dryers, closed drying dehumidifiers, etc., are widely used in food drying, agricultural product drying, wood drying, paint drying, seafood drying, industrial Drying and dehumidification in drying heating, printing drying and other industries.
Relevant technicians of Shuntec Machinery said that after the dewaxing process of wolfberry is completed, it is gradually raised from 35°C to 60°C, and the drying can be completed in about 22 hours. When the fresh fruit is surface-treated, it enters the drying room. The dehydration rate in the drying process is divided into three stages, and there are certain differences in the process of different stages.
