Detailed implementation manners

[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 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 scope of protection specifically claimed by the present utility model.

[0023] The present utility model further improves a tea fixation drum 10 machine with a relatively large length. The purpose of the improvement is to improve the tea fixation effect. There are mainly two improvement points. One is to solve the problem of moisture exhaust of the traditional long drum, and the other is to solve the problem that the temperature of the hot air supplied by the transmission is not enough, resulting in poor tea fixation treatment effect.

[0024] As Figure 1 、 2 shown, a drum tea fixation machine includes a frame 00 and a tea fixation drum 10 rotatably installed on the frame 00. The tea fixation drum 10 has a moisture exhaust section 12 and a working section 11. The working section 11 is used for tea fixation treatment. The barrel wall of the moisture exhaust section 12 has a moisture exhaust structure. The moisture exhaust structure meets the requirement of allowing the tea to advance along the length direction of the drum and enables the moisture at the moisture exhaust section to be discharged to the outside of the drum through the moisture exhaust structure. Through the provided moisture exhaust structure, the generated moisture and dampness can be effectively discharged, avoiding the poor tea fixation effect in the rear section of the tea fixation drum 10 caused by the continuous accumulation of moisture, and improving the moisture exhaust effect. In addition, in the moisture exhaust section 12, the tea can perform moisture redistribution and balance, providing a better tea fixation effect.

[0025] If the tea fixation drum 10 is relatively large, multiple moisture exhaust sections 12 can be provided, so that the working section 11 and the moisture exhaust section 12 are arranged at intervals and staggered along the length direction of the tea fixation drum 10. There are two implementation manners of the moisture exhaust structure. The first one is that the moisture exhaust structure is composed of through holes provided on the barrel wall of the moisture exhaust section 12. AsFigure 4 As shown. The second type is that there is a vacancy part on the barrel wall of the moisture exhaust section 12, and the moisture exhaust structure is composed of a net body 13 provided on the barrel wall. The size of the mesh holes on the net body 13 is determined according to the size of the tea leaves to be processed, and can be specifically set to 0.3 - 3 mm, preferably about 0.5 mm. When implemented in this way, a reinforcing rib is provided between the annular baffles 14 at both ends for connection, the net body 13 is fixed on the reinforcing rib, 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 exhaust 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 exhaust section 12. An outer shell body is also provided on the frame 00, and an installation area for installing the drum is provided inside the outer shell body. The heat insulation structure is composed of an annular heat insulation ring provided between the outer shell body and the green tea killing drum 10, and the annular heat insulation ring 05 is made of a heat-resistant and heat-insulating material. Specifically, as Figure 3 、 5 shown, the outer shell body includes a first shell section and a second shell section. The first shell section corresponds to the working section 11, and the second shell section corresponds to the moisture exhaust section 12. The annular heat insulation ring is fixedly installed at the junction of the first shell section and the second shell section. An annular installation groove is provided at the junction of the first shell section and the second shell section, and the annular heat insulation ring is installed in the annular installation groove. A moisture exhaust air hood 40 for discharging the moisture flowing out of the moisture exhaust section 12 is provided on the second shell section. An adjusting component for adjusting the size of the outlet of the moisture exhaust air hood 40 and a suction fan 43 for sucking the moisture are provided at the upper end of the moisture exhaust air hood 40. The moisture exhaust air hood 40 can be specifically made of a metal plate, and the moisture exhaust air hood 40 is installed vertically.

[0027] Specifically: The outer casing is composed of an upper casing and a lower casing 03. The upper casing includes a first upper casing section and a second upper casing section. The lower casing 03 includes a first lower casing section and a second lower casing section. The second upper casing section and the second lower casing section form the second casing section. An upwardly open trough-shaped lower mounting area is provided on the lower casing 03, and a downwardly open arc-shaped upper mounting area is provided on the first upper casing section. An upper semi-circular mounting groove section is provided at the junction of the first upper casing section and the second upper casing section, and a lower semi-circular mounting groove section is provided at the junction of the first lower casing section and the second lower casing section. The upper semi-circular mounting groove section and the lower semi-circular mounting groove section form the annular mounting groove. The upper semi-circular mounting groove section can specifically be composed of two spaced semi-circular arc-shaped arc plates provided on the first upper casing section. The lower semi-circular mounting groove section can specifically be composed of two spaced partition plates 41 provided on the first lower casing section. A semi-circular arc-shaped vacant portion 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 air duct at the upper end of the moisture exhaust hood 40. The partition plate 41 is arranged in the length direction of the tea-killing drum 10. The partition plate 41 divides the inner cavity of the upper air duct into a first exhaust air channel and a second exhaust air channel. The adjusting assembly includes adjusting damper plates 42 respectively corresponding to the first exhaust air channel and the second exhaust air channel. The suction fan 43 is respectively provided 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 aroma type of the tea undergoing the tea-killing treatment 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 treatments of different qualities, different sizes, and different picking periods, the required moisture exhaust intensity is different. Therefore, by adjusting the opening and closing states of the adjusting damper plates 42 and adjusting the working state of the induced draft fan, the requirements of different moisture exhaust intensities can be met, the adaptability range and the precise control of the moisture exhaust intensity can be improved, and the effect of the tea-killing treatment can be enhanced. Annular baffles 14 are respectively provided at both ends of the moisture exhaust section 12. The annular mounting groove is provided outside the annular baffle 14. Here, the outside refers to the side of the annular baffle 14 away from the middle of the moisture exhaust section 12. Specifically, two annular baffles 14 can be respectively and spacedly provided 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 mounting 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 can be blocked and the requirements for the rotational assembly of the tea-killing drum 10 can be met. An installation vacant portion is provided on the first lower casing section, and a horizontally arranged plate-frame-shaped heating assembly 01 is installed at the installation vacant portion.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 cylinder 10 are the same as those of a traditional drum fixation machine. The two annular heat insulation rings not only have a heat insulation effect but also can block the moisture in the moisture exhaust section from entering the heater, prolonging the service life of the heating electrical components.

[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 cylinder 10 through an air duct 54. By setting the air flow channel for air to flow in a serpentine shape, the flow time of air in the outer housing is increased, thereby prolonging the heating time of the air. As a result, the temperature of the air discharged from the air duct 54 is higher, so as to better perform the fixation treatment on the tea leaves and improve the fixation treatment effect.

[0029] A further solution is as Figure 5 shown: The outer housing is composed of an upper housing located above the fixing cylinder 10 and a lower housing 03 located below the fixing cylinder 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 is that 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 cylinder 10. The air flow units are arranged at intervals along the circumferential direction of the fixing cylinder 10, and the ends of the air flow units are connected in communication. The second is that 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 cylinder 10. The air flow units are arranged at intervals along the length direction of the fixing cylinder 10, and the ends of the air flow units are connected in communication.

[0030] Detailed: 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 provided at each air outlet. The air distributor 53 can specifically be composed of an arc-shaped box body, and the arc-shaped box body and the fixing cylinder 10 can specifically be arranged concentrically. The air outlets can 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 can 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 can be directly extended into the fixing cylinder 10 inside the fixing cylinder 10, and the setting of the air distribution mechanism can be implemented according to the patent applied by the applicant earlier. 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 formed by a clamping cavity portion provided on the first upper shell section, and the second air flow section is formed 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. The second air flow section is composed of a plurality of air flow connecting pipes 51, and the air flow connecting pipes 51 are arranged at intervals along the circumferential direction of the fixing cylinder 10. An odd number of air flow units are arranged along the circumferential direction of the fixing cylinder 10.

[0031] A more specific solution is, such as Figure 6As shown in the figure: The fixing roller 10 is composed of two working sections 11 and an air exhausting 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 fixing roller 10. The A1 upper shell section 20 includes the A11 arc plate 21 and the A12 arc plate 22 which are arranged at intervals and are in an arc plate shape. An A1 clamping cavity is formed between the A11 arc plate 21 and the A12 arc plate 22. The A1 clamping cavity is divided into a plurality of A1 clamping cavity parts 24 through each A1 partition plate 23. The A2 upper shell section 30 includes the A21 arc plate 31 and the A22 arc plate 32 which are arranged at intervals and are in an arc plate shape. An A2 clamping cavity is formed between the A21 arc plate 31 and the A22 arc plate 32. The A2 clamping cavity is divided into a plurality of A2 clamping cavity parts 34 through each A2 partition plate 33. Each A1 clamping cavity part 24 on the A1 upper shell section 20 and each A2 clamping cavity part 34 on the A2 upper shell section 30 are arranged corresponding to each other. The corresponding arranged A1 clamping cavity part 24 and A2 clamping cavity part 34 in the same group are connected and communicated through an air flow connecting pipe 51. An A1 arc 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 buffer plate 25. The A1 arc buffer plate 25 is arranged at intervals along the length direction of the fixing roller 10. An A2 arc buffer plate 35 for buffering the air flow is arranged on the A2 clamping cavity part 34. Each A2 buffer air flow hole 36 for the air flow to pass through is arranged on the A2 arc buffer plate 35. The A2 arc buffer plate 35 is arranged at intervals along the length direction of the fixing roller 10. The A1 clamping cavity is divided into three A1 clamping cavity parts 24 through two A1 partition plates 23. The A2 clamping cavity is divided into three A2 clamping cavity parts 34 through 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 away from the blower 52 along the circumferential direction of the fixing roller 10 is denoted as the A2 communication partition plate 41. An A2 communication air flow hole 37 for connecting and communicating the A2 clamping cavity parts 34 on both sides of it is arranged on the outer end of the A2 communication partition plate 41. Among the two A1 partition plates 23, the A1 partition plate 23 which is closer to the blower 52 along the circumferential direction of the fixing roller 10 is denoted as the A1 communication partition plate 41. An A1 communication air flow hole 27 for connecting and communicating the A1 clamping cavity parts 24 on both sides of it is arranged on the outer end of the A1 communication partition plate 41. The outer end of the A1 clamping cavity part 24 on the A1 upper shell section 20 which is farthest from the blower 52 along the circumferential direction of the fixing roller 10 is connected and communicated with the air distributor 53.

[0032] Through the air flow channel with the above - set structure, the air blown by the blower 52 can be reliably heated, so that the temperature of the air entering the roller 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 - leaf fixing effect is better.

[0033] In summary, the above-mentioned drum green tea fixer provided by the present utility model can effectively discharge moisture and improve the effect of green tea fixing treatment.

[0034] The above are only the preferred embodiments of the present utility model.
