Problems solved by technology

At present, the basic process of processing Junshan silver needles is: spreading → finishing → fresh air → initial baking → initial packaging → rebaking → repacking → drying. In the finishing process, traditional manual pot killing or roller killing is generally used. It is relatively strong, and it is generally difficult to master the degree of greening. It is easy to cause light aroma or burnt smell, bud heads are easy to bend, and the color is not easy to turn yellow, which leads to unstable quality of Junshan Yinzhen.

Embodiment 1

[0017] This embodiment includes the following steps;

[0018] (1) Harvesting fresh leaves of raw materials: Harvesting buds of tea trees in Yueyang Junshan Island tea garden, the buds are 25-30mm long, 3-4mm wide, and the petioles are 2-3mm long;

[0019] (2) Withering: Thinly spread the harvested fresh leaf raw materials, spread them in the withering tank, the thickness of the spread leaves is 3-4cm, wither naturally, turn the leaves twice in the middle, and the withering time is 5 hours;

[0020] (3) Food oven finishing: install a movable finishing screen in the oven, the mesh aperture is 70 mesh, and the amount of leaves per layer is 0.5Kg, which is evenly distributed. Each layer is heated separately at a heating temperature of 260°C. The time is 4.5min, and the color of the bud head turns yellow after the lower leaves are completed;

[0021] (4) Breeze: Spread the green buds thinly on a thin bamboo tray, use an electric fan to quickly dissipate the air, and let it cool fo...

Embodiment 2

[0031] The difference between this example and Example 1 lies in: step (2), the leaves are turned once in the middle, and the withering time is 4 hours; step (3), the heating temperature of the food oven is 275°C, and the time for finishing is 4 minutes; step (4) uses The electric fan quickly dissipates heat and spreads the cooling time for 19 minutes; step (5) initial drying temperature is 102°C, time is 7 minutes, and then bakes down when the water content is 51.5wt%, and then cools down for 22 minutes. The rest are the same as embodiment 1.

[0032] The quality of the Junshan Yinzhen product obtained in this embodiment is very close to that of the Junshan Yinzhen product obtained in Example 1 shown in Table 1, and it is difficult to distinguish it by the senses. This shows that the Junshan Yinzhen product prepared by the present invention has stable product quality.

Abstract

The invention relates to a method for killing out yellow Junshan needle tea, which comprises the following steps: (1) collecting fresh leaves of raw materials; (2) dewatering the leaves; (3) killing out the leaves with a food oven; (4) airing the leaves to dissipate heat by wind; (5) preliminarily drying the leaves; (6) primarily packing the dried leaves; (7) drying the leaves for the second time; (8) packing the leaves for the second time; and (9) completely drying the leaves. The dry Junshan needle tea prepared with the method disclosed by the invention has the advantages of strong and straight shape of tea leaves, russet brown, bright and even color of the tea leaves, light aroma of the tea leaves, mellow taste of the tea leaves, apricot yellow and bright soup, bright yellow, bright and uniform Securinega and stable quality.

Description

technical field [0001] The invention relates to a method for fixing Junshan silver needles, in particular to a method for fixing Junshan silver needles by using an oven. Background technique [0002] Junshan Silver Needle is the most famous tea among the bud-shaped yellow teas. Its quality requirements are as follows: the buds are strong and straight, covered with gold hairs "gold inlaid with jade", the inner quality is pure and sweet, and the soup is light yellow and bright. Three ups and downs when soaking. At present, the basic process of processing Junshan silver needles is: spreading → finishing → fresh air → initial baking → initial packaging → rebaking → repacking → drying. In the processing of greening, traditional manual pot killing or drum killing is generally used. It is relatively strong, and it is generally difficult to master the degree of greening. It is easy to cause light aroma or burnt smell, bud heads are easy to bend, and the color is not easy to turn ye...
