Description

Technical Field

[0001] The utility model patent relates to tea processing equipment, specifically to a tea drying net. Background Art

[0002] Tea drying is an important step in the tea processing process. It is mainly to remove moisture from tea leaves. The moisture and aroma of tea leaves are dried out by high temperature, and the tea leaves are dried to completely eliminate the grassy smell in the tea leaves, so that the tea leaves can be preserved for a longer time and improve the taste and aroma. The general methods of drying tea leaves include sun drying, drying machine, and roasting. Among them, the use of a dryer is a modern drying method. By controlling the temperature and humidity, the tea leaves can be dried quickly, which can better control the drying effect and improve production efficiency.

[0003] The name is "tea drying oven" (document number CN208223030U, hereinafter referred to as document 1). In the document 1, the heat source generates hot air that flows upward from the bottom of the drying oven 10. When the lifting mechanism works, the drying net 20 is stacked and lifted to the top layer of the drying oven 10 in a progressive manner. The baffle 30 is arranged at the opening 12. In this process, it is ensured that the heat will not be directly lost from the opening 12 as much as possible. After the tea leaves are baked, the drying net 20 is extracted layer by layer from the top to the bottom of the drying oven 10. However, there are still some shortcomings: considering that the steam flows from bottom to top, the tea leaves on the upper drying net are affected by the moisture volatilized by the tea leaves on the lower drying net. Therefore, the tea leaves on the lower drying net are dried one step earlier than the upper layer, and the lower drying net should be taken out one step earlier. However, the upper and lower end surfaces of the upper and lower superimposed drying nets are close to each other, so that the outer side surface of the entire drying net forms a relatively dense plane. In the process of taking out the drying net, there is a lack of effective support points on the drying net to support the drying net, making it difficult to take out the drying net pressed below. Summary of the invention

[0004] The utility model provides a tea drying net, which uses a supporting component to support the top surface of the missing space on the drying net and bear all the superimposed drying nets above the supported position to release the pressure constraint of the drying net below the supporting position for easy movement and removal.

[0005] In order to achieve the above-mentioned purpose, the adopted technical solution is: a tea drying net, the drying net has frame rods and a net body arranged in the area surrounded by the frame rods, the mesh surface of the net body is lower than the upper frame surface of the frame rods, and the outer positions of the frame rods of adjacent drying nets overlapped with each other on the upper and lower sides form a missing airspace, and the mass center of the drying net is located within the area enclosed by the supporting position formed by the missing airspace.

[0006] Compared with the prior art, the technical effect of the utility model is as follows: by arranging missing spaces on the opposite sides of the outer frame rods of the adjacent drying nets stacked on each other at the upper and lower sides, a supporting portion for supporting the drying net is formed on the outer side of the frame rods of the drying net. The supporting component supports the top surface of the missing space on the drying net and bears all the stacked drying nets above the supported position, so that the pressure constraint of the supported position and all the drying nets above the supported position on the drying net below the supported position can be released, so that the drying net below the supported position is in a free state and convenient.

[0015] The following is combined with Figure 1-10 And related content, the utility model is further described in detail:

[0016] A tea drying net, the drying net 1 having frame rods 10 and a net body 20 arranged in an area surrounded by the frame rods 10, the net surface of the net body 20 is lower than the upper frame surface of the frame rods 10, the outer positions of the frame rods 10 of adjacent drying nets 1 overlapped with each other on the upper and lower sides form a missing airspace A, and the mass center of the drying net 1 is located within the area surrounded by the supporting position formed by the missing airspace A.

[0017] In the above scheme, missing spaces A are provided on the opposite sides of the outer frame rods 10 of adjacent drying screens stacked on each other at the upper and lower sides, so that a supporting portion for supporting the drying screen 30 is formed on the outer side of the frame rods 10 of the drying screen 1. The top surface of the missing space A on the drying screen 1 is supported by the supporting component and all the stacked drying screens 1 above the supported position are supported, so as to release the pressing constraints of the supported position and all the drying screens 1 above the supported position on the drying screen 1 below the supported position, so that the drying screen 1 below the supported position is in a free state for easy removal. In addition, in the present scheme, in the process of supporting the drying screen 1, the supporting position formed by the missing space A serves as a force-bearing portion. Since the mass center of the drying screen 1 is located within the area enclosed by the supporting position formed by the missing space A, it can ensure that the drying screen 1 is stably supported to prevent the screen surface from sliding due to tilting.

[0018] As a preferred solution, a perpendicular line from the mass center of the drying net 1 to the border rod 10 where the missing space A is set is located within the range where the missing space A is located.

[0019] Furthermore, a concave portion 11 is provided at the lower outer side of the frame rod 10. The concave portion 11 can provide a space for an external force source to be inserted, so as to support the drying net 1 by supporting the concave portion 11, so as to take out the drying net 1.

[0020] In addition, the notch 11 may also be disposed on the upper outer side of the frame rod 10 .

[0021] Furthermore, four upper frame bars 10a are connected end to end to form a square upper frame 11a, and four lower frame bars 10b are connected end to end to form a square lower frame 11b, and the net body 20 is arranged between the upper frame 11a and the lower frame 11b. The upper frame 11a and the lower frame 11b are connected to form the frame bars 10, and the net body 20 can be effectively clamped and fixed between the upper frame 11a and the lower frame 11b. The groove-shaped area enclosed by the inner side surface of the upper frame 11a and the upper end surface of the net body 20 is used to hold tea leaves. With the structure of the upper frame 11a and the lower frame 11b, the net body 20 is clamped between the upper frame 11a and the lower frame 11b, which is conducive to the flat tension and fixation of the net body 20.

[0022] There are two basic forms for constructing the missing space A. One is to use the cross-sectional shape of the frame rod 10, and the other is to use the length difference between the upper frame rod 10a and the lower frame rod 10b. The following is a detailed description.

[0023] Example 1

[0024] Combination Figure 1 , 2As shown, the outer side surface and the bottom surface or the top surface of the frame rod 10 are transitioned by the inclined surface 12 to form a concave portion 11. If the inclined surface 12 is arranged between the outer side surface and the bottom surface of the frame rod 10, when taking the drying net 1, the drying net 1 provided with the inclined surface 12 can be supported by supporting the inclined surface 12; if the inclined surface 12 is arranged between the outer side surface and the top surface of the frame rod 10, when taking the drying net 1, the concave portion 11 formed by the inclined surface 12 can be placed into it by an external force source, and when the drying net 1 is supported, the drying net 1 supported is the drying net 1 of the upper layer of the drying net 1 where the inclined surface 12 is located.

[0025] It should be noted that the frame rod 10 can be a rod profile with a uniform cross-section and a slope 12, and the slope 12 is continuous in the length direction of the frame rod 10, or the slope 12 can be arranged at intervals in the length direction of the frame rod 10. As the latter, the symmetry of the slope 12 in the length direction of the frame rod 10 needs to be considered.

[0026] In order to better illustrate the change of the drying net 1 from the stacking state to the supporting state, Figure 7 , 8 As shown, Figure 7 The figure shows a state where three layers of drying nets 1 are stacked and the inclined surface 12 is located between the outer side surface and the bottom surface of the frame rod 10. Figure 8 The drying net 1 is shown in the state of being supported.

[0027] Example 2

[0028] Combination Figure 3 , 4 As shown, the length of the upper frame rod 10a on the same side is longer than the length of the lower frame rod 10b, and the two ends of the upper frame rod 10a and the two ends of the lower frame rod 10b are arranged at a distance. In this solution, the rod ends of the upper frame rod 10a and the rod ends of the lower frame rod 10b are formed with notches opening downward, and when taking the drying net 1, the notches can be used for external force sources to be placed therein, and when the drying net 1 is supported, the drying net 1 supported is the drying net 1 forming the notch.

[0029] In this embodiment, in order to show the change of the drying net 1 from the stacking state to the supporting state, Fig. 9 , 10 As shown, Fig. 9 The three layers of drying nets 1 are shown in FIG. Figure 8 The drying net 1 is shown in the state of being supported.

[0030] Example 3

[0031] Combination Figure 5As shown, the length of the upper frame rod 10a on the same side is shorter than that of the lower frame rod 10b, and the two ends of the upper frame rod 10a are arranged at a distance from the two ends of the lower frame rod 10b. In this solution, the rod ends of the upper frame rod 10a and the rod ends of the lower frame rod 10b are also formed with notches, but the openings are arranged upward. When taking the drying net 1, the external force source is placed in the notch, and the supported drying net 1 is the upper layer of the drying net 1 forming the notch.

[0032] Example 4

[0033] Combination Figure 6 As shown, there are 2 to 3 upper frame bars 10a on the same side, and the ends of the upper frame bars 10a arranged at intervals are arranged at intervals with the ends of the lower frame bars 10b. Similar to the third scheme, in this scheme, notches with openings facing upwards can be formed between two adjacent upper frame bars 10a and between the rod ends of the upper frame bars 10a and the rod ends of the lower frame bars 10b, and the external force source can be placed in each notch and provide multi-point support. It should be noted that in this scheme, the upper frame bars 10a and the lower frame bars 10b can also adopt the opposite arrangement scheme, that is, the lower frame bars 10a are arranged at intervals of 2 to 3.
