Detail

Tea leaves contain substances called enzymes. Enzymes are biomacromolecules with biocatalytic function, which can speed up or slow down the speed of biochemical reaction without changing the direction and product of the reaction.

Most enzymes consist of proteins (a few are RNA), whose activity is easily affected by temperature, chemical environment and other factors. Under the action of high temperature, the protein molecular structure of enzymes will be irreversibly damaged, thus completely losing enzyme activity. In the process of detoxification, high temperature measures are adopted to transform the fresh leaf contents rapidly.

The "deactivating" of tea leaves makes use of the high temperature deactivating nature of enzymes to stop the activities of oxidase (especially polyphenol oxidase and peroxidase, etc.) in fresh leaves in time.

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 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, the traditional fixation machine requires a preheating process.

2. Even heating.

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 is often the possibility of secondary pollution, microwave fixation, drying with sterilization, mellowing effect, especially for summer and autumn tea, in addition to bitterness and astringency, quite useful.

4. Less material nutrient loss.

Stay in the microwave heating box for a shorter period of time, and 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, the progress of tea processing technology is of great significance.
