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

Embodiment 1

[0013] Baking method of the present invention:

[0014] (1) Preheating: use the Wuyuandou roaster to heat for 30 minutes, and the temperature of the roaster is 75-85 degrees;

[0015] (2) Baking: Put the formed silver ball tea into the bucket pan for baking, keep the temperature at 85-95 degrees, then put the bucket pan into the hot air outlet of the blower, and replace the front and rear bucket pans every 8-12 minutes And roll the silver ball tea in the bucket tray, and recirculate the silver ball tea for 3-4 hours;

[0016] (3) Titian: Pour the dried Yinqiu tea from the bucket pan into the sieve of the Yuandou tea roaster for baking. The baking time is 10-12 minutes and the temperature is 115-125 degrees.

Embodiment 2

[0018] Self-built brick-concrete baking method:

[0019] The bottom of the drying room is composed of a fire stove, a fire ditch and a fire wall. The fire ditch is covered with a pot cover, and coal is used as fuel. There are two moisture-discharging air holes on the top. After the temperature rises, the heat will be dissipated through the pot cover and the fire wall. A thermometer is hung in the drying room. The interior is welded with steel bars or angle steel. -20cm. When the temperature in the drying room reaches above 60 degrees after the fire is raised, pour silver ball tea into the sieve and put the sieve into the drying room to bake at a temperature of 60-80 degrees. The upper and lower layers of the sieve are exchanged every 30-40 minutes Turn the silver ball tea in the sieve to make it bake evenly. After baking for 6-8 hours, take out the silver ball tea and put it in the drying room to enhance the fragrance and make the finished product.

Embodiment 3

[0021] Cabinet type electric control baking method:

[0022] Pour the silver ball tea into the sieve and put the sieve into the roaster, adjust the temperature to 80-100 degrees, and bake for 4-6 hours. After the silver ball tea is dried, pour it into the roaster to enhance the aroma and bake The temperature is 95-105 degrees, and the baking time is 25-35 minutes.

[0023] Table 1 is the finished product contrast data of embodiment 1 and embodiment 2 and embodiment 3:

[0024]

[0025] The test results in Table 1 show that the baking time required by Example 1 is short, the fuel is less, and the cost is low.

[0026] Table 2 is the storage comparison data of the finished Yinqiu tea in Example 1, Example 2 and Example 3:

[0027]

[0028] The test results in Table 2 show that the silver ball tea baked in Example 1 has a long storage time and is not easy to deteriorate.

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. If the drying room is used for too long, there will be ...
