1.

Choose a sunny day with very good sunshine, put the picked sweet potato leaves directly on the concrete floor or on the roof, let the sun shine directly to prevent them from getting wet again and keep them for a long time;

2.

Please clean the ground before drying, or spread a film on the ground to avoid sharp soil or debris mixing with the sweet potato leaves to be dried;

3.

The sweet potato leaves are kept at 35-38 degrees, and aired for 2-3 days at a time. At this time, the leaves are fragrant and easy to store and use.

4.

If there is rain during the drying process or it is not completely dried, if there is a good sun, it will be dried for another two days to prevent mildew and difficulty in preservation.

How to save:

1.

First of all, we will seal it with a double-layer film sealing bag. This kind of sealed bag is usually about 3 meters long, and the bag will always be strong. A bag can hold about 65,438+000 kilograms. After packing, we will use the machine to pump out the air inside.

2.

Secondly, we laid a board in the underground warehouse. This kind of board is generally half a meter wide and 3-4 meters long. Both ends will stand on tiptoe with bricks, and our lotus leaf tea bag will be placed on the board. Usually an underground warehouse will store more than 500 bags. Usually, the dried lotus leaves can be guaranteed to be as fresh as ever.

3.

If it is extremely dry before bagging and well preserved after bagging, you only need to put it in a dry place after receiving it, and it will be fine in a year or two.
