Banana Crispy Freeze Drying Machine

Brief description: The freeze-dried banana slices prepared by the banana chip freeze-drying mechanism have a crispy and non astringent taste, maintaining the original color, shape, and nutritional components of bananas, and have a strong fresh banana aroma. The freeze-drying process is as follows: fresh fruit harvesting, picking, sterilization, cleaning, peeling, pre freezing all slices, freezing, vacuum freeze-drying, exiting the warehouse, and inspecting the packaging.

　　

1. Fresh fruit harvesting

　　

Buy back fresh bananas

　　

2. Picking

　　

Select those that are crushed, moldy, or not mature enough.

　　

3. Sterilization

　　

Soak bananas in a 300ppm sodium hypochlorite solution for 15 minutes.

　　

4. Cleaning

　　

Take out the banana and rinse it with clean water until there is no residual sodium hypochlorite.

　　

5. Peel off the skin

　　

Artificially peel and extract the fruit pulp.

　　

6. Pre freezing

　　

Freeze to a certain temperature in a cold storage.

　　

7. Slice it

　　

In a low-temperature environment, the banana is sliced into slices in a slicer with a thickness of 0.6~0.8cm.

　　

8. Freeze

　　

The eutectic point of bananas is -33 ± 1 ℃, and the freezing temperature is generally 5-10 ℃ lower than the eutectic point temperature of the material, so the freezing temperature of bananas is -40 ℃. The material needs to be frozen to * for a certain period of time, and then maintained for 2-3 hours after reaching the freezing temperature.

　　

9. Vacuum freeze-drying

　　

Set the vacuum degree, cold hydrazine temperature, heating plate temperature, and time on the food freeze dryer, and perform vacuum freeze drying.

　　

10. Out of warehouse

　　

After vacuum freeze-drying is completed, control the temperature and relative humidity of the environment, and then pack it out of the warehouse.

　　

11. Inspection and packaging

　　

Product quality inspection, vacuum packaging
