Description

Technical Field

[0001] This utility model belongs to the technical field of Dendrobium flower tea, and in particular relates to a Dendrobium flower tea drying device. Background Technology

[0002] The processing of Dendrobium flower tea mainly includes several steps such as picking, washing, spreading out and drying. Among them, the drying process can effectively remove excess moisture from the flower tea, prevent mold, and at the same time retain its unique aroma and nutrients.

[0003] In traditional drying equipment, materials are mostly dried by statically spreading them out, which restricts air circulation. This causes the surface material to lose water too quickly while the inside remains damp, affecting the overall drying efficiency and the quality of the finished product. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] This utility model provides a drying device for Dendrobium flower tea, including:

[0006] Drying oven;

[0007] The support assembly is elastically and movably disposed inside the drying oven along the longitudinal direction. The support assembly includes a horizontally arranged support filter screen. Both the upper and lower ends of the support filter screen are fixedly provided with extension rings, and a collection filter screen is threadedly fitted to the outer side of the lower extension ring.

[0008] The shaft is rotatably disposed inside the drying chamber and located below the support assembly. Top blocks are symmetrically arranged on the outside of the shaft. During the rotation of the shaft, the top blocks are driven to intermittently abut against the support assembly, causing it to move up and down reciprocally.

[0009] As a preferred embodiment of the above technical solution, the outer side of the upper extension ring of the carrying filter screen is threaded with a limiting sleeve.

[0010] As a preferred embodiment of the above technical solution, the drying oven has symmetrically arranged fixing blocks on opposite side walls. Each fixing block has a detachable base, which includes a seat body and a vertically extending guide rod. Both ends of the filter screen are provided with sleeves, which are slidably fitted onto the guide rod on their respective sides. A spring is also fitted around the guide rod.

[0011] As a preferred embodiment of the above technical solution, a connecting block is provided at one end of the seat body near the fixing block on the side where it is located, and a bolt is used to lock the connecting block and the fixing block through it.

[0012] As a preferred embodiment of the above technical solution, the drying oven is hinged to a door on its front side.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model uses a supporting component and a top block to achieve elastic up-and-down reciprocating motion through a guide rod and a spring. Under the periodic impact of the top block, the carrying filter screen vibrates, loosening the material and making it easier for hot air to penetrate, greatly improving heat transfer efficiency and effectively avoiding the phenomenon of the surface cracking and the inside being damp. At the same time, during the vibration process, small impurities (such as dust and debris) fall from the filter screen pores and are captured by the collection filter screen, realizing automatic impurity removal.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] Example

[0021] like Figure 1 , Figure 2 As shown, Figure 1 The diagram shown is a front view of the drying apparatus in the embodiment; Figure 2 The diagram shown is a cross-sectional view of the drying apparatus in the embodiment;

[0022] This device includes:

[0023] Drying oven 10, with a door 12 hinged to the front side of the drying oven 10.

[0024] The drying oven 10 is used to hold the Dendrobium flower tea material to be dried, and is equipped with existing heating elements (such as electric heating wires, infrared heating tubes, etc.) and ventilation systems (such as fans) to ensure uniform heating and good air circulation.

[0025] When the door 12 is closed, it can maintain the airtightness of the drying oven 10, preventing heat loss and external contamination.

[0026] like Figure 2 , Figure 3 As shown, Figure 2 The diagram shown is a cross-sectional view of the drying apparatus in the embodiment; Figure 3 The diagram shown is a cross-sectional view of the support component and the base in an embodiment.

[0027] Also includes:

[0028] The support assembly 40 is elastically and movably disposed inside the drying oven 10 along the longitudinal direction. The support assembly 40 includes a horizontally arranged support filter 41. Both the upper and lower ends of the support filter 41 are fixedly provided with extension rings 42. The outer side of the lower extension ring 42 is threaded with a collection filter 44.

[0029] Shaft 21 is rotatably disposed inside the drying chamber 10 and located below the support assembly 40. Top blocks 22 are symmetrically arranged on the outside of shaft 21. During the rotation of shaft 21, the top blocks 22 are driven to intermittently abut against the support assembly 40, causing them to move up and down reciprocally.

[0030] Dendrobium flower tea to be dried is piled on the upper surface of the carrier filter 41. The Dendrobium flower tea cannot pass through the filter holes of the carrier filter 41. The fine impurities mixed in the Dendrobium flower tea can pass through the filter holes of the carrier filter 41 and fall into the collection filter 44 below. Specifically, the collection filter 44 is a filter box with an open top.

[0031] During operation, the rotation of shaft 21 drives top block 22 to periodically contact the bottom of collection filter 44, causing it to vibrate up and down, thereby shaking, loosening and separating impurities from the Dendrobium flower tea and collecting it. The shaking and loosening also increases the gaps between the piled Dendrobium flower tea, making it easier for hot air to penetrate and improving drying efficiency.

[0032] The outer wall of the extension ring 42 is threadedly engaged with the inner wall of the opening end of the collecting filter 44, enabling quick installation and removal of the collecting filter 44.

[0033] Specifically, such as Figure 1 As shown, the drying oven 10 is equipped with a motor for driving the shaft 21 to rotate. The output end of the motor is connected to the shaft 21. In actual application, the shaft 21 should rotate slowly to hit and vibrate the support assembly 40.

[0034] The outer side of the upper extension ring 42, which carries the filter screen 41, is threadedly fitted with a limiting sleeve 43.

[0035] The limiting cylinder 43 is a cylindrical shape with openings at both the top and bottom, and has a moderate height. It cooperates with the edge of the carrying filter 41 to form a barrier area, which forms a physical boundary for the Dendrobium flower tea placed on the carrying filter 41, preventing it from slipping outward or scattering during vibration.

[0036] The drying oven 10 has symmetrically arranged fixing blocks 11 on opposite side walls. The fixing blocks 11 are detachably mounted on bases 30. The bases 30 include a seat body 31. The seat body 31 is provided with a vertically extending guide rod 32. The two ends that support the filter screen 41 are provided with sleeves 45. The sleeves 45 are slidably mounted on the guide rod 32 on their respective sides. The guide rod 32 is also fitted with a spring 33.

[0037] The fixing block 11 is used to install the detachable base 30. The guide rod 32 extends vertically on the base 31 to guide the up and down movement of the filter screen 41. The spring 33 is sleeved on the outside of the guide rod 32 to provide elastic restoring force.

[0038] Specifically, the two ends of the spring 33 are fixedly connected to the seat 31 and the sleeve block 45, respectively.

[0039] A connecting block 34 is provided at one end of the base 31 near the fixing block 11 on the side, and a bolt 35 is used to lock the connecting block 34 and the fixing block 11 through it.

[0040] The connecting block 34 and the fixing block 11 are locked together by bolts 35, so as to achieve a stable and detachable connection between the base 30 and the drying box 10, and the supporting component 40 can be quickly disassembled as needed.

[0041] Working principle: Dendrobium flower tea is stacked in an orderly manner on the upper surface of the support filter screen 41. The limiting cylinder 43 prevents the material from splashing. The heating system is started to dry the tea. At the same time, the motor is started to drive the shaft 21 to rotate. The shaft 21 drives the top block 22 to rotate and periodically impact the bottom of the support component 40. The support component 40 slides vertically under the guidance of the guide rod 32 and the sleeve block 45. The spring 33 provides buffering force during compression and reset, so that the support component 40 can achieve elastic up and down vibration. During the vibration, the Dendrobium flower tea loosens and impurities fall from the holes of the support filter screen 41. The impurities are collected by the collection filter screen 44 below, realizing automatic impurity removal.

[0042] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
