Description

Black tea withering and rolling all-in-one machine

Technical Field

The invention relates to the field of tea processing.

Background

Black tea is generally refined through typical processes of withering, rolling, fermentation, drying and the like, and the color of the dry tea and the brewed tea soup are mainly red.

Withering refers to a process of drying fresh leaves for a period of time to make certain hard and crisp stems into withered state, and is the first process of primary processing of black tea. After withering, the water can be properly evaporated, the leaves are soft, the toughness is enhanced, and the shaping is convenient. Withering fresh leaves are uniformly spread in a withering trough and a withering machine, the thickness of the spread leaves is generally 18-20cm, air flow at about 35 ℃ is blown into the lower part of the withering trough, and the withering time is about 4-5 hours.

The rolling aims to damage the leaf cells after rolling and lead the tea juice to overflow, accelerate the enzymatic oxidation of polyphenol compounds and lay a foundation for forming the specific endoplasm of the black tea; secondly, the blades are rolled into a tight straight rope, the volume is reduced, and the attractive appearance is shaped; thirdly, the tea juice overflows and gathers on the surface of the leaf strips, and is easy to dissolve in water when being brewed, so that the appearance is glossy, and the concentration of the tea soup is increased.

The existing withering and rolling process of black tea is to firstly put fresh leaves into a withering machine for processing and then put into a rolling machine for rolling, so that the processing links of the black tea are increased, and the processing efficiency of the black tea is reduced.

After the withering is finished, the two support rods are synchronously moved upwards, because the support rods incline towards the inner side of the horizontal frame, the distance between the upper ends of the two support rods in the process of moving upwards by the support rods is closer and closer, and because the withering plate is a flexible plate, the withering plate is rolled up by the support rods to be in a cylindrical shape and wraps the rolling rollers in the withering plate. The enclosure is mounted on the end of the withering plate reel remote from the first motor so that the withering plate and enclosure form an enclosed space. The first motor and the second motor are started, the first motor drives the kneading roller to rotate, the spiral on the kneading roller pushes tea leaves to move to the closed shell side between the kneading roller and the withering plate, the tea leaves are kneaded by interaction of the kneading roller and the ribs in the moving process due to the ribs arranged on the withering plate, and the tea leaves are continuously accumulated in the closed shell in the kneading process; because the second motor is connected with the screw rod, a gap is formed between the screw rod and the inner wall of the rolling roller, the second motor drives the screw rod to rotate, the screw rod brings tea leaves in the closed shell into the rolling roller from the inlet, the rotating screw rod rolls the tea leaves and drives the tea leaves to be discharged from one end close to the first motor, the tea leaves fall onto the withering plate and are driven by the rolling roller to be rolled again, and the tea leaves circularly move between the withering plate and the outer side of the rolling roller as well as between the rolling roller and the screw rod and are continuously rolled.

The black tea leaves are mechanically lifted to the rolling roller after being processed on the withering plate, and the withering plate becomes a part of the rolling machine, so that the tea leaves can be immediately rolled, and the processing efficiency of withering and rolling the tea leaves is ensured; the tea leaves circularly move between the withering plate and the outer side of the rolling roller and between the rolling roller and the screw rod, and are continuously rolled, so that the rolling effect of the tea leaves is ensured.

Further, the sides of the withering plate connected with the stay bars have the same length as the length of the rolling rollers, and the other two sides of the withering plate are respectively aligned with the two end surfaces of the rolling rollers. The tea leaves can be brought into the inlet immediately after reaching the closed position and can be brought into the spiral outside the rolling roller immediately after being discharged from the outlet, so that the tea leaves can be circulated between the withering plate and the outside of the rolling roller and between the rolling roller and the screw rod.

Further, a first connecting shaft is connected between the kneading roller and the first motor, a through hole is formed in the first connecting shaft along the axis of the kneading roller, a second connecting shaft is coaxially and rotatably connected in the through hole, one end of the second connecting shaft is connected to the screw, and the other end of the second connecting shaft is connected to the second motor. So that the screw and the twisting roller can coaxially rotate, and the running stability of the twisting roller is improved.

Further, the vertical rod is a telescopic rod. The height of the withering plate can be conveniently adjusted.

Further, the size of air outlet equals the size of withering plate. So that the hot air blown out by the fan can be blown to the whole withering plate.

Furthermore, an opening is arranged on the closed shell, and a stop door is arranged on the opening. The shutter is convenient to open, and tea leaves are directly added into the closed shell from the opening of the closed shell for rolling.
