Embodiment 1

[0027] Granular tea production process, its process steps are:

[0028] (1), fresh tea leaves are crushed to less than 4 orders, and the moisture is controlled at 68%;

[0029] (2), granulation: use YK-160 type oscillating granulator to granulate the crushed fresh tea leaves, the granulation temperature is 40°C, the granulation time is 80 minutes, and the hob speed of the oscillating granulator is 60 rpm / minute, using the interaction of external pressure, squeezing and scraping, using different round sieves to form particle shapes of different sizes;

[0030] (3) High-frequency vibrating sieve: After the tea leaves are granulated, a high-frequency vibrating sieve is used to make the formed tea leaves have a tight internal structure, a bright appearance, and bald particles. The high-frequency vibrating sieve is 3800 rpm;

[0031] (4) Drying: The operation method is divided into hair fire, cooling, and full drying. The temperature of the hair fire is controlled at 140°C; the ...

Embodiment 2

[0033] Granular tea production process, its process steps are:

[0034] (1), fresh tea leaves are crushed to less than 4 orders, and the moisture is controlled at 65%;

[0035] (2), granulation: use YK-160 type oscillating granulator to granulate the crushed fresh tea leaves, the granulation temperature is 35°C, the granulation time is 120 minutes, and the hob speed of the oscillating granulator is 70 rpm / minute, using the interaction of external pressure, squeezing and scraping, using different round sieves to form particle shapes of different sizes;

[0036] (3) High-frequency vibration sieve: After the tea leaves are granulated, a high-frequency vibration sieve is used to make the formed tea leaves have a tight internal structure, a bright appearance, and bald particles. The high-frequency vibration sieve is 3900 rpm;

[0037] (4) Drying: The operation method is divided into hair fire, cooling, and full drying. The temperature of the hair fire is controlled at 135°C; the...

Embodiment 3

[0039] Granular tea production process, its process steps are:

[0040] (1), fresh tea leaves are crushed to less than 4 orders, and the moisture is controlled at 64%;

[0041] (2), granulation: use YK-160 type oscillating granulator to granulate the crushed fresh tea leaves, the granulation temperature is 35°C, the granulation time is 100 minutes, and the hob speed of the oscillating granulator is 65 rpm / minute, using the interaction of external pressure, squeezing and scraping, using different round sieves to form particle shapes of different sizes;

[0042] (3) High-frequency vibrating sieve: After the tea leaves are granulated, high-frequency vibrating sieve is used to make the formed tea leaves have a tight internal structure, a bright appearance, and bald particles. The high-frequency vibrating sieve is 3800-4000 rpm;

[0043] (4) Drying: The operation method is divided into hair fire, cooling, and full drying. The temperature of the hair fire is controlled at 140°C; ...

Abstract

The invention discloses a grain tea production process which comprises the following process steps of: (I) crushing fresh tea leaves into less than 4 meshes and controlling the moisture within 62-68 percent; (II) pelleting: pelleting the crushed fresh tea leaves by adopting an oscillating granulator, wherein the pelleting temperature is 30-40 DEG C, the pelleting time is 80-160 minutes, and the hobbing speed of the oscillating granulator is 60-70 revolutions / minute; (III) high-frequency vibrating sieve utilization: after the tea leaves are pelleted and formed, enabling the inside structures of the formed tea leaves to be compact, the appearances of the tea leaves to be smooth and bright and grains to be bald and compact by utilizing a high-frequency vibrating sieve, wherein the high-frequency vibrating sieve is 3800-4000 revolutions / minute; and (IV) drying: controlling the moisture of a finished product within 7 percent and avoiding high fire, smoke and scorched flavor while drying. The invention relates to the grain tea production process with the advantages of high tea leaf resource utilization rate, high tea leaf quality, environment protection and greenness, low production cost and reduced labor intensity.

Description

technical field [0001] The invention relates to a production process of granular tea. Background technique [0002] my country is the country of origin of tea. It has a long history of tea processing and production. Its tea category ranks first in the world. At present, the broken tea trade in the international market accounts for more than 90% of the entire tea market trade. The broken tea produced by traditional crafts in my country has complicated processing technology, outdated equipment, high production cost, and large waste of resources. The finished product rate is between 50 and 65%, while the proportion of by-products accounts for as much as 40%, and the quality is low, lacking market competitiveness. . Broken tea produced by traditional techniques is curved, irregular in size, and light in texture. When the tea is brewed, the content of water extract is low, and the tea dregs and tea soup are easy to mix, making the soup cloudy, which is no longer suitable for con...
