Banana is one of the most popular fruits. It tastes sweet, has clear heat, and moistens intestines. There are many common banana products on the market, such as juice, jam, and dry banana slices. Dry banana is the dried banana after peeling and cutting, which is easy to store and eat and is a very popular snack. The dried banana is mainly made by hot air drying. Now let’s take a look at the process of drying dried bananas with a banana drying machine.
Processing steps of dried banana
- Raw materials and processing
The raw materials for processing dried bananas require high maturity. Bananas need to reach edible maturity, complete in color, fragrance, and taste. The green banana tastes astringent and cannot be processed. Overripe bananas cannot be processed if they are soft and rotten. When processing raw materials, first pick out the soft and rotten bananas and peel them by hand. The cutting method depends on the size of a single banana. If the individual is large, it should be half-cut or sliced.
- Color protection treatment
The flesh of a banana contains polyphenols. Even mature bananas still contain polyphenols. This will cause it to turn black during the processing and storage of finished products. In order to obtain products with good color and luster, color protection treatment is required.
Lay the processed bananas on the baking tray of the banana dryer evenly and not too thick. Then push the baking tray into the oven. Start the power supply,
Drying process of the banana dryer
- For the first 6 hours, the temperature shall be controlled at 70-75 ℃ and the humidity shall be 35%.
- In the middle 7 hours, the temperature shall be controlled between 65-70 ℃ and the humidity shall be 20%.
- The temperature shall be controlled within 60-65 ℃ and the humidity shall be controlled within 10% in the next 5 hours.
Key points for drying bananas
Bananas are rich in sugar. During the drying process, if the temperature is too high, such as reaching 80 ℃, they will be caramelized. The temperature was too low and the baking time was too long, which did not meet the requirements. Therefore, the drying temperature of the banana chips dryer machine should be controlled between 60 and 75 ℃. The drying time should be completed within 18 to 20 hours. The moisture content of the finished product is required to be 16%.
Why choose a banana drying machine instead of manual one?
The natural drying time is long, and the temperature cannot be controlled, which cannot meet the needs of large-scale production. The air energy heat pump banana drying machine can accurately control the drying temperature and humidity during banana drying. It has the characteristics of zero pollution, low operation cost and high efficiency. It is an indispensable machine for modern production.
