Description

Technical Field

[0001] The utility model relates to the field of green tea production, in particular to a green tea refining and processing system. Background Art

[0002] Green tea products are divided into export and domestic sales. Export sales primarily focus on green tea products sold overseas. Because overseas consumers' tea drinking habits and taste preferences differ slightly from those of domestic consumers, product levels also differ.

[0003] The refining process of green tea involves the classification and packaging of green tea grades. This process directly determines the quality and economic value of the tea. Export tea generally has high requirements for product appearance, such as thickness and length. Furthermore, consumer preferences vary across different countries. For example, Europeans prefer blending green tea with scented teas, resulting in long, slender leaves that look better when brewed. Asians, on the other hand, prefer short, thicker tea leaves for easier brewing. Therefore, existing green tea refining systems need to be designed to meet these requirements. Utility Model Content

[0004] The purpose of the present utility model is to provide a green tea refining processing system to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a green tea refining processing system, which includes a first air separator, a circular screen machine and a shaking screen machine according to the successive steps of the steamed green tea refining process. The circular screen machine and the shaking screen machine are connected in parallel to the output port of the first air separator, the output ports of the circular screen machine and the shaking screen machine are connected to the second air separator, the output port of the second air separator is connected to the dryer, the output port of the dryer is connected to the cooler, the output port of the cooler is connected to the stacking machine, and the output port of the stacking machine is connected to the packaging machine.

[0006] Preferably, the output port of the cooler is also connected to a color sorter, the output port of the color sorter is connected to a magnetic separator, the output port of the magnetic separator is connected to a third air separator, and the output port of the third air separator is connected to a dryer.

[0007] Preferably, the dryer is a rotary drum dryer.

[0008] Preferably, the cooling machine body is an inclined plate vibrating conveyor, comprising an inclined conveyor and a vibration motor mounted on a frame at the bottom of the inclined conveyor, and a spring shaft is connected between the bottom of the frame and the mounting surface.

[0009] Preferably, a partition is installed on the side of the conveying inclined plate, and an air suction port is opened on the partition, and the end of the air suction port is connected to a fan and a dust removal bag.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model targets tea leaves for export, selects steamed green tea leaves as refined products, sets a first air separator, performs preliminary dust removal and sorts the tea leaves according to their quality, and the sorted tea leaves can be selectively fed into a circular screen machine for coarseness screening, or fed into a shaking screen machine for length screening. Since the tea leaves have undergone preliminary quality sorting by the first air separator, the sorting results of the output tea leaves are not much different whether they subsequently enter the circular screen machine or the shaking screen machine. Because the air separator has sorted the quality, the circular screen machine separates out tea leaves of uniform coarseness and fineness, and their lengths are similar. Similarly, the shaking screen machine outputs tea leaves of uniform length and their coarseness is also similar. Selecting different screening machine outputs is to meet consumers' high requirements for uniform coarseness and fineness or high requirements for length. And the processing efficiency will be higher using this method.

[0014] In addition, the utility model is equipped with a stacking machine in front of the packaging machine, which is used to blend tea leaves of different thicknesses and lengths to meet different product needs. A traveling stacking machine can be used. If the product does not require blending, the stacking machine can also be used to further cool the tea leaves, reduce the temperature of the tea leaves after re-firing, and meet quality inspection needs.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Please refer to the figure. This embodiment provides a green tea refining processing system, which includes a first air separator, a circular screen machine and a shaking screen machine according to the successive steps of the steamed green tea refining process. The circular screen machine and the shaking screen machine are connected in parallel to the output port of the first air separator, and the output ports of the circular screen machine and the shaking screen machine are connected to the second air separator. The output port of the second air separator is connected to a dryer, the output port of the dryer is connected to a cooler, the output port of the cooler is connected to a stacking machine, and the output port of the stacking machine is connected to a packaging machine.

[0019] The output of the cooler is also connected to a color sorter, the output of the color sorter is connected to a magnetic separator, the output of the magnetic separator is connected to a third air separator, and the output of the third air separator is connected to a dryer. The color sorter is used to sort the color of tea leaves, and it is needed in some high-end tea products. The magnetic separator mainly uses magnetism to screen magnetic impurities that may be present in the tea leaves, and a metal detector can also be used. After color sorting and magnetic separation, another air sorting is required, because after two stages of screening and transportation, tea fragments and tea dust may be generated, and then drying and cooling are carried out again. It is worth mentioning that two dryers can be set up in series, or one dryer can be used twice. A reasonable production rhythm can be formulated according to the actual tea production needs.

[0020] After the dryer is re-fired and the aroma is enhanced, it needs to be cooled. Existing coolers generally use low-speed conveyor lines for natural cooling or air cooling.

[0021] This embodiment also has a special design for the cooling machine. Figure 2 As shown, the cooling machine body is a slanted plate vibrating conveyor, comprising a conveying slant plate 1 and a vibration motor 14 mounted on a frame at the bottom of the conveying slant plate 1. A spring shaft 15 is connected between the bottom of the frame and the mounting surface. The tea leaves are transported by means of vibration and slanted plates. The vibration accelerates the heat dissipation of the tea leaves and also helps to separate the tea dust. A partition is installed on the side of the conveying slant plate 1, and an air suction port 11 is provided on the partition. The end of the air suction port 11 is connected to a fan and a dust removal bag. The heat and tea dust are discharged synchronously through the air suction port.

[0022] The middle section of the conveying inclined plate 1 is provided with an inclined screen plate 12, which is a leaky structure, and the bottom of the inclined screen plate 12 is provided with a discharge plate 13. Figure 2 As shown, the inclined sieve plate 12 has an upward inclination angle, where the transmission speed of the tea leaves decreases, helping to separate dense tea dust and tea foam from the tea leaves and discharge them through the inclined sieve plate 12.

[0023] After the tea leaves are discharged from the cooling machine, they are piled evenly, which is a further cooling process. This helps to shape the tea leaves and also allows for blending according to export needs. Usually, single-variety teas sold domestically are not blended and piled evenly.

[0024] After uniform stacking, the finished products are packaged.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
