Description

Technical Field

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

[0002] Green tea products are divided into export and domestic sales. Export sales primarily target green tea products sold overseas. Because overseas consumers' tea drinking habits and taste preferences differ slightly from those of domestic consumers, product quality also differs. Continuing with the traditional domestic tea-making process would make it difficult to achieve competitiveness. Therefore, the existing green tea production system is being revamped. Utility Model Content

[0003] The purpose of this utility model is to provide a rough processing system for green tea for export, so as to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a rough processing system for green tea for export, comprising a green tea spreading / steaming composite machine, a rolling machine and a drying machine;

[0005] Among them, the spreading / steaming combined machine is used for spreading and steaming fresh green tea leaves. It includes a steam chamber at the bottom and several layers of shelves installed above the steam chamber in the height direction. The upper and lower shelves are connected by connecting rods. When spreading, the upper and lower shelves are staggered and spread out. When steaming, the upper and lower shelves are vertically stacked.

[0006] A rising chamber is provided at the bottom of the kneading disk of the kneading machine, which is connected to the steam chamber, forming a steam circulation between the rising chamber and the steam chamber.

[0007] Preferably, the shelves include two groups on the left and right, and each group is provided with two layers.

[0008] Preferably, the installation structure of the shelf includes two mutually meshing sector gears installed on the outer wall of the steam chamber, and a first connecting rod is fixedly installed at the axial position of each sector gear, one end of the first connecting rod is hinged to the first shelf, and the second connecting rod also includes one end of the second connecting rod is hinged to the outer wall of the steam chamber, the middle part is hinged to the outer wall of the first shelf, and the other end is hinged to the outer wall of the second shelf, and the third connecting rod also includes one end of the third connecting rod is hinged to the outer wall of the first shelf, and the other end is hinged to the outer wall of the second shelf.

[0009] Preferably, the dryer is a rotary drum dryer.

[0010] Preferably, an air flow microhole is provided in the middle of the kneading disk, and the rising chamber is connected to a position valve of the air flow microhole.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model adjusts the overall process system of green tea primary processing, adopts the steaming method to fix the fresh leaves, and integrates the equipment of spreading and steaming into one, that is, the spreading / steaming composite machine can meet the needs of spreading and steaming at the same time. Since steaming is more efficient than frying and baking, the integration of spreading and steaming does not require additional transportation, which can further improve the fixing efficiency.

[0013] Furthermore, the steamed tea leaves retain much of the chlorophyll in the tea leaves, and have the characteristics of "three greens": the first is the green tea leaves, the second is the green tea soup, and the third is the green tea base. This is very popular in East Asia, such as Japan and South Korea, as well as Western European countries.

[0014] Although the steaming process has the above advantages, the grassy smell of the tea leaves is not volatilized sufficiently due to the short steaming time, which will affect the output of the tea fragrance. Therefore, the utility model transmits the steam in the steam chamber to the rolling machine through a pipeline to heat the rolling plate, promote the volatilization of the grassy smell, and increase the richness of the tea fragrance.

[0020] 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.

[0021] As shown in the figure, this embodiment provides a rough processing system for green tea for export, including a green tea spreading / steaming machine, a rolling machine, and a dryer;

[0022] Among them, the spreading / steaming composite machine is used for spreading and steaming fresh green tea leaves, including a steam chamber 1 at the bottom, and a plurality of shelves 2 installed above the steam chamber 1 in the height direction. The upper and lower shelves 2 are connected by connecting rods. When spreading, the upper and lower shelves 2 are staggered and spread out. When steaming, the upper and lower shelves 2 are vertically stacked. The bottom plates of the shelves 2 are all hollow structures. For the specific structure, refer to Figure 3 as well as Figure 4 As shown, the shelf 2 includes two groups on the left and right, each group is provided with two layers, and the mounting structure of the shelf 2 includes two mutually meshing sector gears 11 mounted on the outer wall of the steam chamber 1, one of which is driven by a motor.

[0023] The axis of each sector gear 11 is fixedly mounted with a first connecting rod 12, one end of which is hinged on the first shelf. The second connecting rod 13 is also included, one end of which is hinged on the outer wall of the steam chamber 1, the middle part is hinged on the outer wall of the first shelf, and the other end is hinged on the outer wall of the second shelf. The third connecting rod 14 is also included, one end of which is hinged on the outer wall of the first shelf, and the other end is hinged on the outer wall of the second shelf. When spreading the greens, start the motor, the sector gear 11 rotates, and driven by the connecting rod, the device is transformed into the following Figure 4 The unfolded state, when steamed, reverse rotation to Figure 3 state, and cover the top with an end cover, and set an exhaust port on the end cover.

[0024] Steam chamber 1 contains a coil of perforated pipes, which receive steam from an external boiler. An electric steam generator can also be installed inside steam chamber 1, as in existing tea steaming machines, but this method is more suitable for steaming small batches of tea. If large quantities of steam are required, it is more convenient to use an external boiler.

[0025] The bottom of the rolling plate 3 of the rolling machine is provided with a heating chamber, which is connected to the steam chamber 1. Specifically, it can be connected to the steam pipeline in the steam chamber 1 through a pipe 15, forming a steam circulation between the heating chamber and the steam chamber. The main function is to heat the rolling plate 3 with the help of the steam temperature, and promote the volatilization of the grassy flavor of the tea leaves during the rolling process. In addition, refer to Figure 5 As shown, the central portion of the kneading plate 3 is provided with airflow holes, and the rising chamber is connected to the airflow holes via a valve. In actual use, the valve can be opened to direct steam to the upper end of the kneading plate 5 to blend with the tea leaves, depending on the tea leaves' condition. For example, some fresh leaves have a low water content and are not softened enough during the kneading process, often forming a stick shape after kneading. In this case, steam can be introduced to further soften the tea leaves.

[0026] Finally, the rolled tea leaves enter the dryer for preliminary drying. The dryer is preferably a rotary drum dryer, which is more suitable for high-efficiency batch drying.

[0027] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
