Example Embodiment

[0007] Example one:

[0008] Using Fuding Dahao, a bud, a leaf, and fresh leaves as raw materials, the indoor temperature is maintained at 14°C, the humidity is 90%, the leaf thickness is 1cm, the cooling time is 8 hours, and the weight loss rate of fresh leaves is 15%. Drum curing machine, the curing temperature is 130℃, and the time is 3 minutes. Biluochun dryer 120 ℃, initial drying, to 22.5% water content. Organizing mechanism bars. The temperature of the dryer is controlled at 80°C, and when it is heated to a moisture content of 12%, it is allowed to cool for 8 hours at room temperature, and the leaf thickness is about 2cm. The temperature of the dryer is controlled at 70°C, and it is dried to dryness, and the moisture content of the finished tea is controlled at 6%.

Example Embodiment

[0009] Embodiment two:

[0010] Taking Fuding Dahao, a bud, a leaf, and fresh leaves as raw materials, the indoor temperature is 22°C, the humidity is 80%, the leaf thickness is 1.5cm, the cooling time is 6 hours, and the weight loss rate of fresh leaves is 20%. Roller curing machine, the curing temperature is 150℃, and the time is 2 minutes. Biluochun dryer, 110℃, initial drying, to 25% water content. Organizing mechanism bars. The temperature of the dryer is controlled at 100°C, and when it is heated to 10% moisture content, let it cool at room temperature for 8 hours, and the thickness of the spread leaf is about 2.5cm. The temperature of the dryer is controlled at 60°C, and it is dried to dryness, and the moisture content of the finished tea is controlled at 5%.

Example Embodiment

[0011] Embodiment three:

[0012] Take Fuding Dahao, a bud, a leaf, and fresh leaves as raw materials, keep indoor temperature at 18°C, humidity at 70%, spread leaf thickness of 0.5cm, spread cool time for 4 hours, and fresh leaf weight loss rate of 25%. Roller curing machine, the curing temperature is 110℃, and the time is 2.5 minutes. Biluochun dryer, 100℃, initial drying, to 40% water content. Organizing mechanism bars. The temperature of the dryer is controlled at 90°C, and when it is heated to 9% moisture content, let it cool for 8 hours at room temperature, and the leaf thickness is about 3cm. The temperature of the dryer is controlled at 80°C, and it is dried to dryness, and the moisture content of the finished tea is controlled at 4%.

Abstract

The invention relates to a method for processing floral-type Taihu bamboo tea. The method can improve aroma of the floral-type Taihu bamboo tea and maintain the aroma for a long time, thereby improving the quality of the finished Taihu bamboo tea. The invention comprises the following processing steps: grading of fresh leaves, spreading and cooling, enzymes-passivating, initial drying, rolling, carding, re-drying, spread-cooling deterioration and adequate fire drying. The invention is characterized in that: when the fresh leaves are spread and cooled, the indoor temperature is maintained at 14-22 DEG C; the humidity is 70%-90%; the thickness of spreading leaves is 0.5cm-1.5cm; the spreading and cooling time is 4-8 hours; and the weight loss rate of the fresh leaves is 15%-25%, wherein the percent content in each step is mass percent;.

Description

technical field [0001] The invention relates to the technical field of tea processing, in particular to a processing method for flower-flavored Taihu green bamboo tea. Background technique [0002] Traditional Taihu Cuizhu tea is a light-flavored green tea, and its raw materials are mainly Fuding Dahao and Fuding Dabai. These two varieties are rich in endoplasmic components, and the quality of processed tea leaves has great room for improvement and improvement. Generally, the processing steps of Taihu Green Bamboo Tea include fresh leaf picking and grading, cooling, greening, initial drying, rolling, stripping, re-drying, cooling and withering, and full-fire drying, because its processing is basically carried out under natural conditions. , especially during the cooling process, the quality of the finished tea leaves is greatly affected by temperature and humidity under natural conditions, and the traditional cooling time is as short as 2 to 4 hours, which makes the aroma of...
