Based on this, the patent No. be 200410081453.8 " a kind of green tea and preparation method thereof " provide one can to solve moulding single, millet paste yellowing and the shortcoming that contained bitterness is highly seasoned and amino acid content is low, but but only with the blade containing bud, and or even green tea is prepared in the dark brownish green of leaf one bud, does not improve completely, say nothing of the rich of the nutriment that should contain inside tea to the utilization rate of tea resource, and in prior art, tea production cost is general higher.

Summary of the invention

In order to solve the technical problem existed in above-mentioned prior art, the invention provides a kind of simple to operate, the making full use of of tea resource can be improved, enrich the nutriment in tea and reduce the processing method of green tea of tea production cost.

Particularly, the processing method of green tea, by the harvesting that fresh tea tree is dark brownish green, to dark brownish green carry out spreading out blue or green, by blue or green for the stand good dark brownish green process that completes, spreading for cooling, knead, cure, be shaped, drying, the production technology of classified placement is made, and its concrete processing step comprises:

(1) harvesting that fresh tea tree is dark brownish green: after first 25 days to the Ching Ming Festival of the annual Ching Ming Festival 10, April to May and September to November plucks the fresh dark brownish green of tea tree;

(2) stand is blue or green: inside bamboo dustpan, carry out stand green grass or young crops by plucking after come fresh dark brownish green cleans up;

(3) complete: blue or green for stand good dark brownish green high-temperature boiler of putting into is carried out the process that completes, and the dark brownish green amount put into each time inside boiler is 1-2kg, dark brownish greenly to roll with the frequency of 10-20 time/min inside boiler;

(4) spreading for cooling: by the dark brownish green spreading for cooling that completes among bamboo dustpan, the thickness of spreading for cooling is 0.5-1.5cm, and spreading for cooling to temperature is 45-50 degree Celsius;

(5) knead: good dark brownish green of spreading for cooling is kneaded, until tealeaves epidermis outer rim cell rupture, stop when betraying liquid and do not drop kneading;

(6) cure: by knead dark brownish green put into curer cure to moisture be 40-45%;

(7) be shaped: dark brownish green the carrying out of curing is organized into bar shaped or aciculiform;

(8) dry: to be 5-10% by the dark brownish green moisture that is dried to be shaped;

(9) packing: dried tealeaves is carried out classified placement, can obtain green tea.

Described stand green grass or young crops carries out among normal temperature, and the thickness of stand green grass or young crops is 2-5cm.

Moisture after described stand green grass or young crops is 89-92%.

The described temperature that completes is 250-300 degree Celsius.

After described spreading for cooling, moisture is 45-50%.

The described temperature of curing is 180-200 degree Celsius.

The temperature of described drying is 60-90 degree Celsius.

Technique effect of the present invention is embodied in: by Various Seasonal to dark brownish green harvesting, tea resource can be made full use of, improve the utilization rate of tea resource, to be completed step by stand green grass or young crops simultaneously, effectively eliminate the not mature taste contained by dark brownish green inside, by the process of kneading, the dark brownish green element of tea inside and Tea Polyphenols are kneaded to epidermis again, and dark brownish green table edge is kneaded cell rupture, make at utmost to contact with oxygen in the process of curing, dark brownish green element and Tea Polyphenols is made to resolve into aromatic substance, ensure the fragrant of tea, simultaneously easily brewed millet paste time, nutriment is more easily soaked out, final drying classified placement, ensure that the shape of tealeaves and the chronicity of preservation, through shirtsleeve operation, reduce the cost of production process.
