Everyone is familiar with banana chips, do you know how banana chips are made?
1. Raw material and slice processing
The processing of dried banana raw materials has higher requirements on maturity, that is, the period when it reaches edible maturity and has good color, aroma, and taste. Soft, rotten, and diseased bananas are sorted out first, then peeled and sliced with a banana slicer.
2. Color protection treatment
The banana pulp contains polyphenols. Even ripe bananas contain polyphenols in the pulp, which can cause browning during finished product processing and storage. In order to obtain products with good color and luster, color protection treatment must be carried out. Dip banana slices in lemon juice. This will enhance the flavor and vitamins, but the main purpose is to keep the banana chips from browning.
3. Dry the banana slices
Use the wind generated by the air dryer to blow off the moisture on the surface of the banana slices. With the conveyor belt of frequency conversion speed regulation, it is set as a flat net conveying according to the characteristics of banana slices.
4. Banana slices for seasoning
The seasoning machine is mainly used for the post-processing of banana slices or the coating and blending of raw materials to stir seasoning powder. The whole machine is made of stainless steel, with reasonable structure, firm welding, a bright surface, easy cleaning, and no noise.
Bananas are high in sugar. If the temperature is too high during the drying process, such as 80 degrees Celsius, the sugar will be caramelized. If the temperature is too low, the baking time will be too long. Neither meets the requirements. Therefore, the drying temperature should be controlled at 60-65 degrees Celsius, and it can be dried in 18-20 hours. The moisture content of the finished product is required to be 16%.
The fruit and vegetable dryer adopts a large air volume axial flow fan to work in circulation. Through the built-in electric heating tube, it is equipped with a high-power thyristor controller, PID digital display intelligent temperature controller, relay, and other control devices. The temperature control precision is high, and the appointment time can be realized. Function, automatic constant temperature, automatic dehumidification, and other functions, over-temperature automatic alarm, making the control more humane.
How much does a banana chip production line cost?
Banana slicers, air dryers, seasoning machines, dryers, and other mechanical specifications are different, and different models can be selected according to output requirements. Different models have different prices. Generally speaking, it is more advantageous to choose the finished product price.
