Sea Buckthorn or Hippophae rhamnoides Drying Technology
Drying sea buckthorn is a crucial step aimed at extending the shelf life and preserving the nutritional content of the berries. Fresh sea buckthorn has a high water content and is prone to spoilage, making drying an essential method for prolonging its shelf life. During the drying process, it is important to control the temperature and humidity to prevent the berries from spoiling or burning.
Advantages of Drying Sea Buckthorn with Our Heat Pump Technology
1. Significant Energy Savings: The efficiency ratio of heat pump drying technology is 400%-500%, far exceeding the thermal efficiency of traditional energy sources (usually below 100%). This means that for the same drying task, heat pump drying technology consumes much less energy.
2. Environmentally Friendly: The heat pump drying process is conducted in a closed system, reducing thermal deformation and discoloration, and minimizing the loss of flavor substances.
3. Easy Control of Drying Parameters: The temperature, humidity, and flow rate of the circulating air in the heat pump drying process can be precisely and effectively controlled. Therefore, heat pump drying is suitable for the drying of heat-sensitive materials, and the quality of the dried product is higher than that of general convective drying.
4. Wide Range of Adjustable Drying Conditions: The wide range of temperature adjustment in heat pump drying makes it suitable for the drying of various materials.
5. Improved Drying Efficiency and Quality: Compared to other drying methods, heat pump drying technology has shorter drying times and higher drying rates, making it suitable for the drying of large-fruited sea buckthorn.
6. Reduced Energy Consumption and Browning: By using a staged temperature and humidity control combined with infrared hot air drying technology, the drying time, energy consumption, and browning degree were reduced by 34.43%, 36.29%, and 21.43%, respectively. The whiteness, rehydration rate, total flavonoid content, and total phenolic content were increased by 8.94%, 16.99%, 20.57%, and 28.32%, respectively.
In summary, heat pump drying technology demonstrates significant advantages in the drying process of sea buckthorn, including energy saving, environmental friendliness, high drying efficiency, and high-quality drying results. These advantages make heat pump drying technology the preferred solution for sea buckthorn drying.
