Process method improving quality of Yinqiu tea

Abstract

The invention relates to the technical field of tea leaf processing, in particular to a process method improving the quality of Yinqiu tea. The process method comprises the following steps: (1), preheating: heating with a five-round hopper baker for 30 minutes wherein the baking temperature is 75-85 DEG C; (2) baking: placing shaped Yinqiu tea into hopper plates for baking, keeping the temperature at 85-95 DEG C, then placing the hopper plates into a hot air port of a blower, replacing the front and rear hopper plates every 8-12 minutes and turning over the Yinqiu tea in the hopper plates, and circularly baking the Yinqiu tea for 3-4h; (3) perfuming: pouring the baked Yinqiu tea into a sieve of a round hopper tea leaf baker from the hopper plates for baking with the baking time of 10-12 minutes and the baking temperature of 115-125 DEG C. The Yinqiu tea produced by the process method cannot be yellowed and is not easily mildewed after long storage time.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a process method for improving the quality of Yinqiu tea. Background technique [0002] Yinqiu tea is a kind of green tea, which is refined from high-quality tea leaves with one bud and one leaf, and one bud and two leaves. There are two types: special grade and first grade. The appearance is spherical, weighing about 2.5 grams, the diameter of the spherical shape is 18-20mm, and the surface is dark green. After the tea leaves are boiled, the tea water is yellow-green, with a fragrant, mellow and sweet taste. [0003] There are two baking methods for Yinqiu tea, one is the self-built brick-mixed baking method, and the other is the cabinet-type electric-controlled baking method. The disadvantages of using the self-built brick-mixed baking method are: There is a lot of fuel, it takes a long time, and the cost is high.

Problems solved by technology

[0003] There are two baking methods for Yinqiu tea, one is the self-built brick-mixed baking method, and the other is the cabinet-type electric-controlled baking method. The disadvantages of using the self-built brick-mixed baking method are: There is a lot of fuel, it takes a long time, and the cost is high. If the drying room is used for too long, there will be smoke leakage and cracking of the fire wall. The roasted tea has a smokey smell, is unhygienic, and the fire temperature is not easy to control. Self-built brick-mixed baking machine The moisture discharge port of the tea is small, so the moisture, steam and exhaust gas generated during the baking process of the silver ball tea are discharged slowly, resulting in unstable temperature in the drying room, and the produced silver ball tea is yellow in appearance and prone to mildew

Disadvantages of the box-type electronically controlled baking method are: the moisture discharge hole and the internal volume are small, and the waste gas, moisture and steam generated during baking are discharged very slowly, which leads to the appearance of the baked silver ball tea tends to turn yellow, and It requires multiple roasters to operate simultaneously to meet production requirements, and it takes a long time and costs a lot
