During the banana drying process, the optimum temperature for the conversion of sugar into monosaccharide in the banana is 55-60 degrees. The processing of banana dried includes natural drying and heat pump air drying. The natural drying time is long and the temperature cannot be controlled. To meet the needs of large-scale production, the air energy heat pump banana dryer can accurately control the drying temperature and humidity during the drying process, which can achieve zero pollution, low operating cost and high efficiency. It is an indispensable machine for modern production.

Bananas can be dried whole or sliced. Slices can be sliced or sliced in half. The drying process is the same. Now the technology air heat pump dryer is the most energy-saving and environmentally friendly dryer.

1. Pre-drying treatment: Select ripe bananas, classify them by size and peel them.
2. Tile before drying: The paving of the raw materials should be uniform and not too thick.

• For the first 6 hours, the temperature is controlled between 70-75 degrees Celsius and the humidity is 35%.
• In the middle period of 7 hours, the temperature is controlled between 65-70 degrees Celsius, and the humidity is 20%.
• For the last 5 hours, the temperature should be controlled between 60-65 degrees Celsius and the humidity should be 10%.

Note: The drying temperature should not be too fast, which will affect the color and quality of the product. The drying time should not be too long, which will affect the taste and freshness of the product.

Selection of raw materials: choose the fruits with dense flesh, high sugar content, thin skin and thick flesh, and fully mature fruits, and remove rotten and disabled fruits.

Raw material treatment: In order to remove the pesticides on the peel, the fruit is washed with running water. Peel and peel the fruit manually or mechanically, cut into 7-8 mm thick discs, and then put them in salt water.

Color protection: Put the cut apple slices in a solution of 3% to 5% saltwater to protect the color to avoid oxidation and browning.

If the fruit pieces are floating on the potion, they should be pressed with a cover curtain weight on the fruit pieces to ensure that the fruit pieces are completely immersed in the potion.

The banana dryer can realize all aspects of intelligent regulation of temperature, humidity, and circulating air volume, multi-time zone temperature and humidity settings, automatic intelligent dehumidification, and dehumidification, and ensure the internal circulation of bananas with different temperature and humidity requirements in different drying time periods and large air volume. The system ensures that the moisture emitted by the bananas can be taken away in time during the drying process. On the other hand, it can also make the bananas in different positions in the drying room obtain the same amount of heat, which ensures the uniformity of the material. During the entire drying and dehumidification process Using intelligent heat recovery, the energy utilization rate is greatly improved.
