Wire mesh fencing is not commonly used in withering troughs. Withering troughs are typically used in the tea industry for the initial stage of tea processing, where freshly plucked tea leaves are spread out to wither and lose moisture. The purpose of withering troughs is to provide a controlled environment for the withering process, allowing the tea leaves to undergo enzymatic changes that develop the desired flavor and aroma. It’s important to consider the specific needs and requirements of the withering process when selecting appropriate materials and structures for tea processing. When considering materials, one might explore the potential benefits of utilizing wire mesh for tea industry applications. This versatile material could offer advantages in terms of durability, ventilation, and ease of cleaning, which are all crucial factors in ensuring a successful withering process.
