Problems solved by technology

[0005] When the tea rolling equipment is running, the ambient temperature of the workshop and the friction of rolling will generate heat, which will make the internal temperature of the equipment too high and the heat cannot be dissipated to the outside. In addition, during the rolling process, the tea juice overflowing from the damaged leaves will come into contact with oxygen, making The non-enzymatic oxidation of polyphenols leads to the transformation of tea soup towards yellow, which seriously affects the green aroma, color quality and taste of green tea, and greatly reduces the quality characteristics of green tea

Embodiment 1

[0033] Such as Figure 1~3 As shown, a tea low-temperature rolling device includes a driving device 4, a rolling cylinder 1, and a rolling roller 2 arranged in the rolling cylinder 1 and moving in an eccentric circle along the axis of the rolling cylinder 1. Feed port 11 and discharge port 12, said kneading drum 1 is provided with an annular air supply pipeline 3 externally connected to the nitrogen generator near the end of discharge port 12, and said air supply pipeline 3 is provided with a plurality of kneading cylinder 1 Inclined nozzle 31; the kneading drum 1 is arranged obliquely.

[0034] The driving device 4 may be any one of a hydraulic pump, an air pump or a geared motor. The second driving device 5 is a geared motor.

[0035] The kneading barrel is provided with an eccentric shaft, the axis of the eccentric shaft is on the same straight line as the axis of the kneading disc, and the end of the eccentric shaft far away from the kneading barrel is connected to the d...

Embodiment 2

[0040] This embodiment is improved on the basis of Embodiment 1, and its improvement is that: the kneading roll 2 includes a roller 13 and an air pressure layer 14 sleeved on the roller 13; the rib 16 is arranged on Air pressure layer 14 surface.

[0041] The roller 13 is made of metal material or stone with high density and high hardness, preferably metal iron or granite.

[0042] The air pressure layer 14 is an air bag made of a polymeric organic material filled with gas, and the air pressure layer 14 is located between the roller 13 and the inner surface of the kneading cylinder 1, so that the roller 13 of strong hardness is not in contact with the kneading cylinder 1. The tea leaves on the air pressure layer 14 are in direct contact with the tea leaves, and the gas in the air pressure layer 14 is compressible. The air bag made of polymer organic material has a certain elasticity, so that in the process of rolling the tea leaves, the gas flows and compresses in the air pressu...

Embodiment 3

[0047] This embodiment is improved on the basis of Embodiment 1 or 2, and the improvement is that: the inner surface of the kneading drum 1 is provided with a number of ribs 15 arcuately extending from the inlet 11 to the outlet 12 The outer surface of the kneading roller 2 is provided with a plurality of ribs 16 arcuately extending from one end of the feed port 11 to one end of the discharge port 12 . The number of ribs 15 in the kneading cylinder 1 is 12-15; the number of ribs 16 on the kneading roller 2 is 8-10.

[0048] Preferably, the surface of the air pressure layer 14 is provided with several ribs 16 for increasing the surface friction of the air pressure disc, and the ribs 16 are just opposite to the extending direction of the ribs 15 on the kneading roller 2 .

[0049] Other parts in this embodiment are basically the same as those in Embodiment 1, so details will not be repeated one by one.

Abstract

The invention discloses a low-temperature twisting device for tea leaves. The low-temperature twisting device comprises a driving device, a twisting drum and a twisting roller, wherein the twisting roller is arranged in the twisting drum and does eccentric circular motion along the axis of the twisting drum; a feed opening and a discharge opening are formed in two ends of the twisting drum; an annular air supply pipeline connected with a nitrogen making machine externally is arranged on one end close to the discharge opening, of the twisting drum; multiple nozzles inclining towards the inner part of the twisting drum are arranged on the air supply pipeline; and the twisting drum is arranged in an inclined manner. According to the low-temperature twisting device for tea leaves, disclosed bythe invention, nitrogen is inflated into the twisting drum capable of performing continuous twisting, heat generated in the twisting process of the tea leaves is removed, and the oxidation of oxygenon tea liquor in the twisting process is eliminated, so that the tea leaves are better in chromaticness, taste and fragrance; and besides, the tea twisting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of tea rolling equipment, in particular to a tea rolling device at low temperature. Background technique [0002] Tea is a drink made from the leaves or buds of the Camellia sinensis plant that originated in China. It also generally refers to the leaves of the evergreen shrub tea tree that can be used to make tea, and the beverages made from these leaves, and later extended to all herbal teas made from plant flowers, leaves, seeds, and roots, such as "Tieguanyin" and so on. As a well-known health drink, tealeaves is the contribution of the people in southern China to the Chinese food culture in ancient times, and it is also the contribution of the Chinese people to the world's food culture. [0003] Tea rolling refers to the process of rotating the withered leaves or green leaves under a certain pressure, destroying the tea cell tissue, causing the tea juice to overflow, and at the same time making the tea ...
