The processing of cinnamon usually involves the following steps:

2. Peeling: The harvested bark needs to be peeled off with other tools to expose the inner layer.

3. Sun-drying: The stripped endodermis needs to be dried or exposed to the sun to remove moisture. After drying, the color of the endodermis will darken and become brittle and hard.

4. Curling: The sun-dried inner layer needs to be curled to form the typical cinnamon bark shape. The process usually involves cutting, arranging, and curling the inner layer into usable cinnamon bark.

5. Packaging and Storage: Finally, the processed cinnamon bark is packed to prevent moisture and contamination. They are usually kept in dry form for long-term storage and use.

It should be noted that different regions and different processing plants may have slightly different processing methods and processes, but the above steps are the usual cinnamon processing procedures.
