Description

Technical Field

[0001] The utility model relates to the technical field of tea cooling, in particular to a cooling and spreading leaf device for a steam-killing tea-grinding production line. Background Art

[0002] Tencha is a traditional Chinese tea processing method, also known as "rolling". This processing method originated in China. During the production process, green tea leaves are rolled by machine or by hand. Tencha is a traditional Chinese tea production process that can be traced back to the Tang Dynasty. There are different processes in the process of tea making, among which tencha is an important step. The main purpose of the tencha process is to squeeze out the mesophyll and intracellular fluid of the tea leaves to make the tea leaves softer and increase their aroma and taste. The tencha process is generally carried out after the processes of killing green tea and rolling. The cooling and spreading device of the steam-killing tencha production line is a device used to cool the tea leaves after steam treatment. In the tencha production process, the temperature of the tea leaves is high after steam killing green tea. If it is not cooled, it may cause the quality of the tea to deteriorate or other problems in the subsequent processes. Therefore, the cooling and spreading device is to quickly cool the steam-treated tea leaves to a suitable temperature to ensure the taste and quality of the tea.

[0003] After searching, the Chinese patent document announcement number: CN209202029U discloses a tea continuous withering rotary airing and cooling device, which includes a withering machine, a mesh drum and a bracket, wherein the mesh drum is tiltedly installed on the bracket through a bearing seat, and the mesh drum is connected to a driving device; a fan for blowing and cooling the tea leaves in the mesh drum is installed on the bracket on the side of the mesh drum; a collecting trough is installed at the discharge port of the withering machine; a conduit is connected to the discharge port of the collecting trough, a blower is installed at one end of the conduit, and the other end of the conduit is connected to the high end of the mesh drum; the tea leaves are discharged from the low end of the mesh drum. This device can continuously wither and quickly cool the tea leaves, improve the supply efficiency to the rolling process, and provide a basic guarantee for ultimately ensuring the soup color, aroma, and taste of green tea products.

[0004] Regarding the above-mentioned related technologies, the inventor believes that the above patents mentioned in the specific implementation methods: "Withering is a key process in green tea processing. The principle is to take high-temperature measures to dissipate the moisture in the leaves, inactivate the activity of enzymes, and cause certain chemical changes in the contents of fresh leaves, thereby forming the quality characteristics of green tea. In the withering process, the withered leaves cooling technology has always been a key link in ensuring the quality of green tea. The withering machines currently used in various places are divided into dry heat withering machines and wet heat withering machines according to the withering heating method. They can be divided into pot withering machines, drum continuous withering machines, steam withering machines, microwave withering machines, etc.; the traditional withering process withering leaf cooling technology generally adopts a conveyor-type machine to cool through the conveying process or directly spread on the ground to cool. These methods often cause the withered leaves to be cooled in time, resulting in the leaves being kept at high temperature for too long, which is one of the reasons why the green tea soup color becomes darker and water and stuffiness are produced, which directly affects the quality of green tea. In the cooling process of green tea withering, the traditional conveyor-type natural cooling is generally used However, the temperature of the tea leaves was not cooled down in time, which directly affected the quality of the final green tea product. The rotary drying and cooling device for continuous tea withering has a simple structure and ingenious arrangement. It can wither tea leaves continuously and quickly dry and cool the tea leaves after withering. The cooling efficiency of tea withering is more than five times that of traditional tea withering. It solves the problem that the withering leaves cannot be cooled down in time and the production capacity of the tea process is affected by the traditional cooling models and technologies. It speeds up the cooling speed of the withering leaves and improves the supply efficiency to the rolling process, which provides a basic guarantee for the ultimate guarantee of the soup color, aroma and taste of the green tea product. Although the above patent spreads the tea leaves out for cooling by rotating, tea leaves will accumulate during the specific operation process, causing the tea leaves on the bottom side to hinder the flow of hot air. The upper tea leaves cool quickly while the temperature of the bottom tea leaves is still high, affecting the overall cooling effect and tea quality. Therefore, in view of the above shortcomings, a cooling and spreading device for steam withering and tea rolling production line is proposed. Utility Model Content

[0039] Working principle: We first pour the steam-killed ground tea into the feed hopper 1 and let it fall to the top side of the partition plate 7. At this time, the driving motor 5 drives the rotating shaft 6 to rotate, thereby driving multiple partition plates 7 to evenly load the tea leaves to avoid tea accumulation, thereby facilitating the loading of tea leaves. Then the tea leaves evenly distributed on the partition plates 7 will fall to the top side of the air-permeable plate 17. At this time, the rotating shaft 6 will also drive the driving wheel 8 to rotate, thereby driving the driven wheel 11 to rotate, and use the friction between the driven wheel 11 and the driven shaft 10 to drive the driven wheel 11 to rotate, and then drive the driven shaft 10 to rotate. At the same time, the driven shaft 10 will also drive the cylinder 12 to rotate inside the transport box 2 to prevent the driven shaft 10 from slipping, and the driven shaft 10 will also drive the two annular openings 14 to rotate, and use The center of the circular plate 13 is misaligned with the center of the driven shaft 10, so that the annular opening 14 can use the annular opening 14 opened inside to push the sliding column 15 to slide up and down when rotating, and then drive the supporting block 16 to slide up and down, thereby pushing the air-permeable plate 17 to drive the tea leaves on the top side to move up and down, so that the tea leaves can be evenly spread and transported, and the tea leaves will also turn over due to vibration, so that the tea leaves can be cooled in all aspects by the cold air blown by the cooling fan 3, so as to avoid the accumulation of tea leaves and the inability to cool the tea leaves covered on the bottom layer, thereby improving the overall cooling effect and tea quality, and the air-permeable plate 17 will also drive the side block 18 to slide outside the fixed column 20 and squeeze the spring 19, so that the spring 19 can store elastic potential energy, and then give the air-permeable plate 17 a reciprocating elastic force, thereby improving the efficiency of transportation;

[0040] When the tea leaves are transported to the left side of the air-permeable plate 17, the cylinder 23 is driven so that the cylinder 23 can push the strip plate 24 to slide left and right, and then drive the support rod 25 to slide, thereby driving the disc 26 to slide on the inner wall of the opening plate 28. The opening plate 28 will be restricted by the support shaft 27, so that the two discs 26 can respectively push one opening plate 28 to rotate outside the support shaft 27, so that the distance between the two opening plates 28 is adjustable, so as to facilitate the gathering of scattered tea leaves together, and the different distances between the two opening plates 28 can be used to adapt to collection frames of different widths, thereby expanding the scope of application of the device.
