[0033] process flow
[0034] Fresh leaves—spreading—finishing—primary kneading—second greening—re-kneading—organization—drying.
[0035] The fresh tea leaves used for the study of stripping technology were collected from the experimental tea garden of the Tea Research Institute of Chongqing Academy of Agricultural Sciences (29°75′N, 105°71′E, 440m above sea level) on March 30, 2016. One bud of the Fuding Dabai tea tree variety One leaf is carried out, and the needle-shaped famous tea is processed according to the above-mentioned technological process, and the specific parameters are shown in Table 1.

The present invention provides a method for making famous needle-shaped tea with variable temperature and frequency. The famous needle-shaped tea produced by adopting high-medium-high variable-temperature and frequency-variable method has a tighter, thinner and straighter shape than the constant temperature and constant frequency method. , dark green, bright light green soup, fresher aroma with chestnut aroma, fresher and mellow taste, bright yellow-green leaf bottom, aroma and taste quality of the inner quality are significantly better than the constant temperature and constant frequency method. Simultaneously, the invention shortens the constant temperature and constant frequency stripping time, saves electric energy, and also reduces the noise generated by the vibration of the stripping machine.
Description
technical field [0001] The invention relates to needle-shaped famous tea, in particular to a method for making needle-shaped famous tea with variable temperature and frequency. Background technique [0002] Needle-shaped famous tea is one of the main types of famous teas in my country. It is popular among consumers because of its tight, round and straight shape, emerald green and oily color, green and bright soup color, rich and long aroma, fresh and mellow taste, and bright green and bright leaves. favorite. The main technological process of its processing is: fresh leaves-spreading-fixing-kneading-initial drying-shaping-drying; the shaping is a series of physical and chemical changes, energy transfer and mutual conversion under the combined action of heat and force. The process is not only the key to forming a beautiful appearance, but also an important process to develop the inner quality. At present, the production method is mainly based on the vibration method. In the...
