Question

What is entirely processing method of 30%​

Answer 1

Explanation:

Here, the thick and still immalleable leaf is rid of approximately 30% of its humidity. There are two methods:

a) The natural withering where the leaves are spread out on laths which are covered with jute, wire or nylon nets. The withering time takes, depeding on the weather and humidity content of the leaves, between 14-18 hours.

b) The modern withering in large troughs of a length of 25-30 metres which are covered with wire grids and are ventilated with large ventilators. These can also be used to warm the leaves, should it be necessary, to reduce the withering time to 8-12 hours.
