Abstract
The invention relates to the field of tea production, and provides a method for grouting and enzyme deactivation of bulk tea, (1) grouting treatment, namely, spraying domestic drinking water on fresh tea, wherein the ratio of the fresh tea to the domestic drinking water is 1kg of the fresh tea and 50ml of the domestic drinking water; b. the water-removing process is carried out immediately after the domestic drinking water is sprayed, and the time interval between the spraying of the domestic drinking water and the putting of the water-removing process is not more than 1 min; (2) c, selecting different types of enzyme deactivating machines according to the fresh tea leaves of different grades, and selecting 6CST-50 and 6CST-60 roller continuous enzyme deactivating machines for the fresh tea leaves of special grade; d. the fresh tea leaves of other grades are selected from 6CST-60, 6CST-70 and 6CST-80 roller continuous fixation machines. According to the invention, water is added into the fresh tea before the water-removing step, so that the water content of different parts of the tea is improved, the uneven water distribution caused by spreading and drying is avoided, the same batch of tea cannot be easily caused during water-removing, and the tea leaves are uneven and have residual green gas or burnt gas after the water-removing due to different putting times.
Description
Technical Field
The invention relates to the field of tea production, in particular to a method for grouting and enzyme deactivation of bulk tea.
Background
The green tea and the bulk tea are mostly made from fresh leaves in summer, the fresh leaves are made from one bud, three leaves, four leaves and the end of a new tip, the leaves and stems are mixed, and the processing technology comprises the steps of enzyme deactivation, rolling, secondary enzyme baking, three-enzyme frying, shaping and final roasting. Wherein, the continuous roller fixation machine is adopted in the fixation process, the fixation leaf amount is large, and the method is suitable for the production of bulk tea. However, the water content of the tea leaves and the tea stalks is different, the average water content cannot be obtained through spreading and cooling, the temperature of fresh tea leaves in the same pot is too high, the leaves are easy to explode, the temperature is too low, the green stalks cannot be completely killed, and the green grass flavor is serious.
Disclosure of Invention
The invention provides a grouting water-removing method for bulk tea, which aims to solve the problems that the average moisture content cannot be obtained by spreading and drying in the air due to different water contents between leaves and stalks, leaves are easy to explode when the temperature of a water-removing machine is too high, green stalks cannot be completely removed when the temperature of the water-removing machine is too low, and green grass flavor is serious.
In order to solve the technical problem, the invention adopts the following technical scheme:
a method for grouting and enzyme deactivating of bulk tea comprises the following steps,
(1) grouting treatment
a. Spraying domestic drinking water on fresh tea leaves, wherein the ratio of the fresh tea leaves to the domestic drinking water is 1kg, and 50ml of the domestic drinking water is used for the fresh tea leaves;
b. the water-removing process is carried out immediately after the domestic drinking water is sprayed, and the time interval between the spraying of the domestic drinking water and the putting of the water-removing process is not more than 1 min;
(2) deactivating enzymes
Selecting different types of fixation machines according to the fresh tea leaves with different grades,
c. the special grade fresh tea selects a 6CST-50 and 6CST-60 type roller continuous fixation machine, and the temperature of the roller continuous fixation machine is set as follows: 270 DEG-320 ℃;
d. the rest levels of fresh tea leaves are selected from 6CST-60, 6CST-70, 6CST-80 type roller continuous fixation machine, the temperature of the roller continuous fixation machine is set to be 270-320 ℃ in 6CST-60 type, and 300-380 ℃ in 6CST-70, 6CST-80 type;
preferably, in the step (2), when the tea leaves are put into the fixation machine, the putting amount of the tea leaves is increased first and then decreased.
The invention has the beneficial effects that:
according to the invention, the fresh tea leaves are treated by adding water before the water-removing step, so that the water content of different parts of the tea leaves is improved, the water distribution is prevented from being uneven during spreading and drying, the same batch of tea leaves cannot be easily caused during water-removing, and the tea leaves are uneven and the green air is remained or burnt after the water-removing of the tea leaves due to different putting time.
