Exploring Yunnan's Tea Country

Good tea needs sun-drying

Yunnan Sun-Dried Tea

Yunnan is one of China's tea regions!

In Yunnan,

How is the tea's "sun-dried flavor" created?

What kind of tiles are best for a good drying shed?

Sun-drying Tea

"Sun-dried Flavor"

Sun-drying green tea refers to air drying, where the rolled tea leaves are naturally dried in sunlight, maximizing the retention of organic matter and active substances in the tea leaves. The sun-drying process now also involves many considerations:

First, keep it 80~100 centimeters off the ground, drying it on specially built racks.

Second, for sun-drying green tea, it's best to use "segmented drying"; the rolled tea buds have a water content of about 58~60%. In the initial stage of sun-drying, the main purpose is to remove moisture.

"Sun-dried flavor" is the flavor produced during this sun-drying process.

Sun-drying, with a relatively lower temperature than machine drying and a longer time, retains more of the fresh leaves' natural substances, which is beneficial for the transformation of tea substances. The resulting tea has a rich taste and a unique sun-dried flavor.

Good tea requires a complex sun-drying process, and a good drying shed is key to achieving the "sun-dried flavor"!

A Good Drying Shed

Needs good tiles

In some economically underdeveloped areas, drying sheds use bamboo or wood frames to support plastic sheeting, mainly for rain protection.

In the ancient tea mountains of Yunnan, the entire ancient tea garden surrounds the Lancang River basin, which has both dry and rainy seasons. For example, spring tea is in the dry season, and at this time, we can completely place the tea leaves to be dried in winnowing baskets and dry them directly in the sun.

However, in the rainy season and the first half of autumn, the tea mountains receive a lot of rain, almost every day.

In the past, rain-grown tea and autumn tea were of poor quality, with cloudy liquor and off-flavors. This was because the tea leaves to be dried were collected indoors during rain, resulting in a certain degree of air drying and possibly semi-drying, which significantly damaged the essence of Pu'er tea.

Furthermore, in the tea farmers' homes, there are inherent household smells that contaminate the tea leaves, resulting in more off-flavors. The drying time is long, and during this air-drying and sun-drying process, some fermentation or even spoilage occurs.

Therefore, in recent years, local governments and tea farmers have launched large-scale initiatives to improve their initial processing environment, especially focusing on drying sheds.

Today, many Yunnan farmers have installed Hongbo PC transparent corrugated tiles on their drying sheds!

Hongbo PC Transparent Tiles

Tiles that Produce Good Tea

The function of a drying shed is to protect from rain, increase the indoor temperature to speed up tea drying, and prevent the absorption of household odors, smells, and smoke from the tea farmers' homes.

In sunlight drying, the main factor is the infrared spectrum in sunlight, which raises the temperature of the tea leaves through irradiation to achieve drying. Retaining the infrared photosynthesis in sunlight while minimizing ultraviolet damage to the tea is the key to the green tea drying process.

A good drying shed should not only shield some ultraviolet rays but also allow infrared rays to raise the temperature, ensuring high-quality tea!

Hongbo PC Transparent Corrugated Tiles:

① Fire-retardant.

② High strength, lightweight.

③ Good weather resistance, suitable for large temperature differences.

④ Transmittance up to 90%, UV resistant.

Hongbo PC transparent corrugated tiles are made using Covestro polycarbonate PC engineering plastic and high-concentration UV masterbatch as the main raw materials, using co-extrusion technology, with a UV layer thickness of 50μm. Drying sheds built with Hongbo PC transparent corrugated tiles not only retain the infrared photosynthesis in sunlight, making the shed heat up quickly and reach high temperatures, allowing for rapid tea drying,

but also avoid direct sunlight exposure of the tea leaves, reducing UV damage to the tea, resulting in a "sun-dried flavor," enhancing the tea's aroma and freshness, and achieving higher tea quality!
