The high temperature heat pump dryer is suitable for drying raisins, litchi, longan, mountain slag, red dates, walnuts, medlar, siraitia, nuts, cured meat, seafood, traditional Chinese medicine, Guilinggao powder, dried noodles, persimmon cakes, tea, chrysanthemum, glossy ganoderma, honeysuckle, mushrooms, cordyceps flowers, dried vegetables, Rolls of dried bean milk creams, anise, fennel, sesame, sludge, wood and other items.
High temperature heat pump dryerThe advantages of applying it to dehydrated vegetable production are as follows:
(1) Save energy
Energy conservation is the starting point and main advantage of the initial application of heat pumps. High temperature heat pump drying technology can significantly shorten the drying time, and the required time will not exceed 8 hours. Generally, it can be completed in 4 hours from preheating to product release, saving up to 90% energy.
(2) Good quality of dried products
Heat pump drying is a gentle drying method that is close to natural drying. The evaporation rate of surface moisture is relatively close to the migration rate of internal moisture to the surface, resulting in good quality, good color, and high product grade of the dried item. The aromatic volatile substances obtained by ordinary drying methods have low retention, vitamins with poor heat resistance have low retention, and color changes are significant. Vegetables and food dryers produced using high-temperature heat pump drying technology have good color and stable internal quality.
(3) Drying parameters are easy to control and have a wide adjustable range
During the heat pump drying process, the temperature, humidity, and circulation flow rate of the circulating air can be accurately and effectively controlled, with a temperature adjustment range of -20 to 100 ℃ (with auxiliary heating devices) and a relative humidity adjustment range of 15% to 80%, suitable for drying heat sensitive materials. The heat pump dryer system has a high degree of automation and achieves unmanned operation, which can save a lot of labor costs.
(4) Safe and environmentally friendly, food grade natural drying
Material drying not only requires improving product quality and saving energy consumption, but also must be environmentally friendly. Traditional drying rooms generally use coal and wood as fuel materials, which can generate a large amount of smoke and exhaust gas, causing significant pollution to food drying and other drying processes. The high-temperature heat pump dryer system uses heat pump drying equipment for item baking, and the unit eliminates the pollution of exhaust gas and waste residue caused by combustion; And there is no external medium that changes the texture of the baked object, making it more natural and environmentally friendly.
