DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0023] The present utility model further improves the tea withering drum 10 machine with a relatively large length. The purpose of the improvement is to enhance the tea withering effect. There are mainly two aspects of improvement. One is to solve the problem of moisture discharge of the traditional long drum, and the other is to solve the problem that the hot air temperature supplied by the transmission is insufficient, resulting in poor withering treatment effect.

[0024] As Figure 1 , 2 shown, a withering device for improving the withering effect includes a frame 00 and a withering drum 10 rotatably installed on the frame 00. The withering drum 10 has a moisture discharge section 12 and a working section 11. The working section 11 is used for withering tea. The barrel wall of the moisture discharge section 12 has a moisture discharge structure, and the moisture discharge structure meets the requirements for the tea to advance along the length direction of the drum and enables the moisture at the moisture discharge section to be discharged to the outside of the drum through the moisture discharge structure. By setting the moisture discharge structure, the generated moisture can be effectively discharged, avoiding the poor withering effect in the latter section of the withering drum 10 caused by the continuous accumulation of moisture, and improving the moisture discharge effect. In addition, in the moisture discharge section 12, the tea can be rebalanced in terms of moisture distribution, providing a better tea withering effect. The withered tea will be greener in color. Solving the moisture discharge problem can greatly reduce the water vapor concentration of the fresh leaves during withering, avoid the appearance of stuffy smell, and a better fragrance can be formed during this process. For example, if the quality of the tea is good, an orchid fragrance can be formed.

[0025] If the withering drum 10 is relatively large, multiple moisture discharge sections 12 can be set, so that the working section 11 and the moisture discharge section 12 are arranged at intervals and staggered along the length direction of the withering drum 10. There are two implementation methods of the moisture discharge structure. The first one is that the moisture discharge structure is composed of through holes provided on the barrel wall of the moisture discharge section 12, as Figure 4 shown. The second one is that there are vacancy parts provided on the barrel wall of the moisture discharge section 12, and the moisture discharge structure is composed of a mesh body 13 provided on the barrel wall. The size of the mesh holes on the mesh body 13 is determined according to the size of the tea to be processed, and can be specifically set to 0.3 - 3 mm, preferably about 0.5 mm. When implemented in this way, reinforcing ribs are provided between the annular baffles 14 at both ends for connection, and the mesh body 13 is fixed on the reinforcing ribs, and the reinforcing ribs are arranged at intervals along the circumferential direction of the drum.

[0026] A further solution is that a heating component 01 for heating the drum is provided on the outer side of the barrel wall of the working section 11, and a heat insulation structure is provided at the junction of the working section 11 and the moisture discharge section 12. The heat insulation structure is used to prevent the heat generated by the heating component 01 from being conducted from the outer side of the working section 11 to the outer side of the moisture discharge section 12. A housing is also provided on the frame 00, and an installation area for installing the drum is provided inside the housing. The heat insulation structure is composed of an annular heat insulation ring provided between the housing and the withering drum 10, and the annular heat insulation ring 05 is made of heat-resistant and heat-insulating materials. Specifically, as Figure 3 , 5As shown, the outer casing includes a first casing section and a second casing section. The first casing section corresponds to the working section 11, and the second casing section corresponds to the moisture exhaust section 12. The annular heat insulation ring is fixedly installed at the junction of the first casing section and the second casing section. An annular installation groove is provided at the junction of the first casing section and the second casing section, and the annular heat insulation ring is installed in the annular installation groove. A moisture exhaust hood 40 for discharging the moisture flowing out of the moisture exhaust section 12 is provided on the second casing section. An adjustment assembly for adjusting the size of the outlet of the moisture exhaust hood 40 and a suction fan 43 for sucking the moisture are provided at the upper end of the moisture exhaust hood 40. The moisture exhaust hood 40 can be specifically made of a metal plate and is installed vertically. The two annular heat insulation rings not only have a heat insulation effect, but also can block the water vapor in the moisture exhaust section from entering the heater, prolonging the service life of the heating electrical components.

[0027] Specifically: The outer shell body is composed of an upper shell body and a lower shell body 03. The upper shell body includes a first upper shell body section and a second upper shell body section. The lower shell body 03 includes a first lower shell body section and a second lower shell body section. The second upper shell body section and the second lower shell body section form the second shell body section. An upwardly open trough-shaped lower installation area is provided on the lower shell body 03. An arc-shaped upper installation area with a downward opening is provided on the first upper shell body section. An upper semi-circular installation groove section is provided at the junction of the first upper shell body section and the second upper shell body section. A lower semi-circular installation groove section is provided at the junction of the first lower shell body section and the second lower shell body section. The upper semi-circular installation groove section and the lower semi-circular installation groove section form the annular installation groove. The upper semi-circular installation groove section can specifically be composed of two arc-shaped plates arranged at intervals on the first upper shell body section. The lower semi-circular installation groove section can specifically be composed of two partition plates 41 arranged at intervals on the first lower shell body section. A semi-circular arc-shaped vacant part is provided on the upper side edge of the partition plate 41. The moisture exhaust hood 40 is arranged vertically. A vertically arranged partition plate 41 is provided in the upper duct of the moisture exhaust hood 40. The partition plate 41 is arranged along the length direction of the tea-killing drum 10. The partition plate 41 divides the inner cavity of the upper duct into a first exhaust air channel and a second exhaust air channel. The adjustment assembly includes adjustment gate plates 42 respectively corresponding to the first exhaust air channel and the second exhaust air channel. The suction fan 43 is respectively arranged corresponding to the first exhaust air channel and the second exhaust air channel. Humidity adjustment in the tea-killing drum 10 is the core to improve the quality of tea killing. If the moisture is exhausted too quickly, the fragrance type of the tea processed by tea killing will be poor. If the moisture is exhausted slowly and the humidity in the tea-killing drum 10 is too high, the color of the tea will be poor. Therefore, it is necessary to precisely adjust to maintain the humidity in the tea-killing drum 10 within a certain range to ensure reliable tea-killing treatment of the tea. For tea-killing treatment of tea with different qualities, different sizes, and different picking periods, the required moisture exhaust intensity is different. Therefore, by adjusting the opening and closing state of the adjustment gate plate 42 and adjusting the working state of the induced draft fan, the requirements of different moisture exhaust intensities are met, the adaptation range and the precise control of the moisture exhaust intensity are improved, and the effect of tea-killing treatment is enhanced. Annular baffles 14 are respectively provided at both ends of the moisture exhaust section 12. The annular installation groove is arranged outside the annular baffle 14. Here, the outside refers to the side of the annular baffle 14 far from the middle of the moisture exhaust section 12. Specifically, two annular baffles 14 can be respectively arranged at intervals at both ends of the moisture exhaust section 12. The annular baffle 14 can not only improve the performance of blocking heat conduction between the working section 11 and the outside of the moisture exhaust section 12, but also enhance the strength of the moisture exhaust section 12. There is a clearance fit between the annular heat insulation ring and the outer wall of the drum, and there is a clearance fit between the annular baffle 14 and the annular installation groove. The outer diameter of the outer ring of the annular baffle 14 is greater than the inner diameter of the inner ring of the annular heat insulation ring. Thus, the heat conduction is blocked and the requirement for the rotational assembly of the tea-killing drum 10 is met. An installation vacant part is provided on the first lower shell body section, and a horizontally arranged plate-frame-shaped heating component 01 is installed at the installation vacant part.The specific heating component 01 includes a plate-frame-shaped heating mounting base and an electric heating component 01 arranged on the heating mounting base. The electric heating component 01 can be an electric heating wire. The bottom of the groove of the second lower housing section can be set to be vacant or in other structural forms. The installation methods at both ends of the fixing roller 10 are the same as those of the fixing equipment that can improve the fixing effect traditionally.

[0028] Furthermore, a serpentine air flow channel for air to flow is arranged on the outer housing. One end of the air flow channel is connected to the blower 52, and the other end of the air flow channel is connected to the barrel cavity at the feeding end of the fixing roller 10 through an air duct 54. By setting the air flow channel for air to flow in a serpentine shape, the time for air to flow in the outer housing is increased, thereby prolonging the heating time of the air. Furthermore, the temperature of the air discharged from the air duct 54 is higher, so as to better fix the tea leaves and improve the fixing effect.

[0029] A further solution is as Figure 5 shown: The outer housing is composed of an upper housing located above the fixing roller 10 and a lower housing 03 located below the fixing roller 10. The air flow channel is arranged on the upper housing. During specific operation, there are the following two implementation methods, which can be selected according to specific operations. The first one is: The air flow channel is composed of long-strip-shaped air flow units. The length direction of the air flow units is the same as the length direction of the fixing roller 10. The air flow units are arranged at intervals along the circumferential direction of the fixing roller 10, and the ends of the air flow units are connected in communication. The second one is: The air flow channel is composed of arc-shaped air flow units. The length direction of the air flow units is the same as the circumferential direction of the fixing roller 10. The air flow units are arranged at intervals along the length direction of the fixing roller 10, and the ends of the air flow units are connected in communication.

[0030] Details: An arc-shaped air distributor 53 is provided at the upper outer side of the feeding end of the fixing cylinder 10. The other end of the air flow channel is connected to the air inlet provided on the air distributor 53. The air distributor 53 is provided with air outlets at intervals along the circumferential direction of the fixing cylinder 10, and air supply pipes are respectively arranged at each air outlet. The air distributor 53 may specifically be composed of an arc-shaped box body, and the arc-shaped box body and the fixing cylinder 10 may specifically be arranged concentrically. The air outlets may be arranged at equal intervals on the air distributor 53. Preferably, the density of the air outlets corresponding to the tea fixing area is greater than that corresponding to other areas. The tea fixing area is the area where the tea is distributed in the fixing cylinder 10 during tea fixing. A feeding hopper 04 may be provided at the feeding end of the fixing cylinder 10 to avoid interference with the feeding hopper 04. In addition, a air distribution mechanism for blowing hot air directly into the fixing cylinder 10 may also be arranged in the fixing cylinder 10, and the arrangement of the air distribution mechanism may be implemented according to the patents previously applied by the applicant. The air flow unit includes a first air flow section corresponding to the cylinder body of the working section 11 and a second air flow section corresponding to the cylinder body of the moisture exhaust section 12. The first air flow section is constituted by a clamping cavity portion provided on the first upper shell section, and the second air flow section is constituted by an air flow connecting pipe 51 provided on the second shell section. The adjacent two first air flow sections on the same air flow unit are connected and communicated through the air flow connecting pipe 51.

An odd number of air flow units are arranged along the circumferential direction of the fixing cylinder 10.

[0031] A more specific solution is, for example Figure 6As shown in the figure: The de-enzyming drum 10 is composed of two working sections 11 and one moisture exhaust section 12. The two first upper shell sections arranged corresponding to the two working sections 11 are respectively denoted as the A1 upper shell section 20 and the A2 upper shell section 30. The A1 upper shell section 20 is arranged corresponding to the feeding end of the de-enzyming drum 10. The A1 upper shell section 20 includes the A11 arc-shaped plate 21 and the A12 arc-shaped plate 22 which are arranged at intervals and are in the shape of arc-shaped plates.

The same group of correspondingly arranged A1 clamping cavity parts 24 and A2 clamping cavity parts 34 are connected and communicated through an air flow connecting pipe 51. An A1 arc-shaped buffer plate 25 for buffering the air flow is arranged on the A1 clamping cavity part 24. Each A1 buffer air flow hole 26 for the air flow to pass through is arranged on the A1 arc-shaped buffer plate 25.

The A1 clamping cavity is divided into three A1 clamping cavity parts 24 by two A1 partition plates 23, and the A2 clamping cavity is divided into three A2 clamping cavity parts 34 by two A2 partition plates 33. The outlet of the blower 52 is connected and communicated with the outer end of an A2 clamping cavity part 34 located at the edge. Among the two A2 partition plates 33, the A2 partition plate 33 which is farther from the blower 52 along the circumferential direction of the de-enzyming drum 10 is denoted as the A2 communication partition plate 41.

[0032] Through the air flow channel with the above-mentioned structure arranged, the air blown by the blower 52 can be reliably heated, so that the temperature of the air entering the drum is higher. Compared with the traditional scheme, the air flow temperature at the outlet of the air supply port can be increased by 40 - 60 °C, and the tea de-enzyming effect is better.
