蓝莓是一种营养丰富的美味水果。蓝莓含有大量的花青素，不仅具有良好的营养保健作用，还可以延缓身体衰老、保护眼睛。我们的烘干机可去除蓝莓中多余的水分并保留营养成分以供长期保存。蓝莓干也继承了蓝莓的优点，营养和口感与新鲜水果相比几乎没有差异。
新鲜蓝莓的保质期相对较短。传统的蓝莓干是在阳光下晒干的。但蓝莓在夏季采收，成熟期为每年6-8月。但夏季雨水较多，这给传统干燥方法加工蓝莓干造成了很大困难。另外，蓝莓干的品质参差不齐，晒干需要大量的劳动力和时间，无法适应工业化、规模化生产。
Our air-energy heat pump blueberry dryer adopts a scientific drying curve and dehumidification curve so that the blueberry maintains its natural color after drying without damaging its effective nutrients (such as anthocyanins). At the same time, the equipment has a high degree of automation and does not require special supervision. The drying process is all completed by intelligent control.
The advantages of blueberry drying room
这种蓝莓干燥机使用纯净的热空气在干燥室中不断循环。在对物料加热的过程中，热空气带走干燥时产生的水分，达到干燥的目的。
干燥箱中的烘箱、托盘等部件均采用不锈钢材质，不仅干净卫生，而且坚固耐用，使用寿命长。它甚至配备了自动控制系统，让您轻松操作。
During the drying process, the materials are placed in stationary trays, which is not prone to adhesion and can maintain the original shape and color of the materials. Based on the above characteristics, the blueberry drying room is especially suitable for drying fruits, vegetables, and Chinese medicinal materials which have high-quality requirements.
The process of drying blueberries
蓝莓干的生产过程主要包括挑选、清洗、放置、干燥、检验、分选和包装等。
- Material selection: Choose ripe fresh blueberries as raw materials, and require no obvious damage on the surface, no insect eyes, and no decay.
- Cleaning: Pour the blueberries into the 3% sodium hydroxide solution to clean the wax on the surface, otherwise the water in the middle will not evaporate easily, and then rinse it with clean water.
- Placement: Arrange the cleaned fruit pieces evenly on the plate, not overlapping, pile up, and there must be a gap between the fruit. When placing the fruit, be careful to prevent it from breaking.
- 烘干： 蓝莓含糖量高，容易锁住水分。蓝莓的干燥过程长达20小时。干燥过程需要分四个阶段完成。
- The first stage: Put the blueberries in the drying room. At this time, set the temperature to 45°C and the relative humidity to 20%, and use the drying and dehumidification mode for 8 hours.
- The second stage: At this time, most of the water in the blueberries has been discharged. Set the temperature to 55°C and the humidity to 15%. The drying mode is used to strengthen the dehumidification to further remove the water in the blueberries. This stage lasts for 6 hours.
- The third stage: In this stage, the temperature is set to 40°C, and the temperature difference can speed up the distribution of water in the fruit to shorten the drying time. At this time, set the humidity to 10% for 4 hours.
- The fourth stage: In the last stage, the drying system is used to no longer heat, and only the fan continues to circulate so that the blueberry moisture is naturally dried in the drying room. After 2 hours, the dried blueberry fruits can be obtained.
