Detail

Why do tea leaves need to have fixation process?

Tea leaves contain a substance called enzymes. Enzymes are biological macromolecules with biocatalytic function, a kind of biological catalyst, which can speed up or slow down biochemical reactions, but do not change the direction and products of the reaction.

Most of the enzymes are composed of proteins (a few are RNA), and their activities are easily affected by temperature and chemical environment, etc. Under the action of high temperature, the protein molecular structure of enzymes will be irreversibly damaged, thus completely dissipating the enzyme activity. The greening process is to take high temperature measures, so that the fresh leaf inclusions are rapidly transformed.

Tea "fixation", it is the use of this high temperature inactivation of the nature of the enzyme, in time to stop the fresh leaves in the oxidase (especially polyphenol oxidase and peroxidase, etc.) activities.

The purpose of tea fixation(kill-green).

1. Destroy the polyphenol oxidase activity in fresh leaves by using high temperature in a short time, inhibit the enzymatic oxidation of polyphenols, and make the inclusions form the color, aroma and taste of green tea, black tea, black tea, yellow tea and pu’er tea under non-enzymatic action and other quality characteristics.

2. Remove part of the water to make the leaves change from hard to soft, which is convenient for rolling and forming.

3. Remove the green grass smell of fresh leaves, and emit charming tea fragrance.

Microwave fixation(kill-green) is a new type technology, which is faster, more efficient and more effective than traditional equipment such as pot fixation and drum fixation method. Microwave can also remove more than ten percent of the moisture of fresh leaves during fixation process.

Microwave fixation machine is now widely used in tea, chrysanthemum, honeysuckle, lotus leaves, barley seedlings, various flowers and other agricultural products, remarkable fixation effect.

1. Fast heating speed. Microwave directly heats the tea leaves inside and outside at the same time, no need to preheat, and machine can be used when it is turned on. In contrast, traditional fixation machine requires a preheating process.

2. Heating evenly. Microwave fixation is to irradiate the tea leaves evenly through the electromagnetic waves generated by the magnetron tube, which heats the tea leaves inside and outside at the same time, without scorched edges and scorched leaves, etc.

3. Sterilization and mellowing effect is great. Materials in the picking, production process, there has big possibility of secondary pollution, microwave fixation drying machine also have sterilization and mellowing effect, especially for summer and autumn tea, remove bitterness and astringency, quite useful.

4. Less material nutrient loss. Stay in the microwave heating box for a shorter period of time, does not require air and steam heat conduction, so it can retain the nutrients in the material to a large extent.

5. Reduce labor intensity and improve efficiency. The microwave equipment adopts automatic loading and unloading, worker only needs to press the button, monitor the machine operation and patrol fixation effect, the whole process only needs 1~2 people.

6. Non-pollution and environmental protection equipment. The equipment does not produce environmental high temperature, smoke and noise, which is the ideal pollution-free, energy-saving and environment-friendly equipment in the current tea industry.

Compared with the traditional coal-fired steam method, the comprehensive cost of microwave greening and drying can be reduced by 8.5 percentage points, and the selling price of processed tea is much higher. Replace the coal-fired, wood-fired energy supply with electrical energy, no noise, no smoke, no dust, and microwave has a strong sterilization effect, greatly improve tea quality. At the same time, microwave technology has changed the way tea workers work, reducing the labor intensity, have great significance progress for tea processing technology.
