Description

Technical Field

[0001] This utility model relates to the field of drying equipment technology, and in particular to a corn silk tea drying device. Background Technology

[0002] Corn silk tea is a beverage made primarily from corn silk. The preparation of corn silk tea requires drying the washed corn silk for longer storage. Because corn silk tea is lightweight, airflow must be minimized during drying to prevent it from scattering in the air. Therefore, most existing corn silk tea drying equipment uses a drying lamp for roasting. The corn silk tea is placed on a hopper and then placed under the drying lamp for drying.

[0003] According to utility model patent CN219869000U, a corn silk tea drying device includes a frame with two belt rollers symmetrically and horizontally mounted on its top. The device also includes a drying component comprising a conveyor belt and drying lamps. The conveyor belt is tensioned and mounted on the two belt rollers of the frame, and multiple drying lamps are evenly fixed laterally on the outer end face of the conveyor belt. A material holding component includes a material holding frame, a fixing plate, and a material dispensing component. The material holding frame is positioned directly below the conveyor belt, and a fixing plate is located on one side of the material holding frame and fixed to the frame. A rotating shaft, rotatably connected to the fixing plate, is horizontally fixed to one end of the material holding frame. A slot is formed through the end face of the material holding frame away from the fixing plate, and a material dispensing component for holding the corn silk tea is horizontally inserted into the slot. This utility model overcomes the problem of uneven drying of corn silk tea caused by existing methods using drying lamps.

[0004] While the above-mentioned technical solution can dry corn silk tea, the drying rack does not have a heat preservation function and can only be dried by drying lamps. This not only results in poor drying effect and long working time, but also wastes energy. In addition, the amount of corn silk that can be dried at one time is limited, and its applicability is not high. Utility Model Content

[0005] The purpose of this invention is to provide a corn silk tea drying device that can not only dry corn silk tea, but also keep it warm during the drying process. It can also dry a large amount of corn silk at a time, improving work efficiency and reducing energy waste, thus enhancing its applicability.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A corn silk tea drying device includes an insulated box with an open front end, a door hinged to and sealed to one side of the insulated box opening, a heat-conducting frame with an open front end that matches the inner wall of the insulated box, gaps between the outer wall of the heat-conducting frame and the inner wall of the insulated box, a sealed connection between the front end of the heat-conducting frame and the front end of the inner wall of the insulated box, electric heaters that match the inner wall of the insulated box and contact the outer wall of the heat-conducting frame installed on the left and right sides and the rear end of the inner wall of the insulated box, and multiple U-shaped fixing frames that are equally spaced and arranged from bottom to top along the height direction of the inner wall of the heat-conducting frame, each fixing frame having a sliding groove that is oppositely arranged on the left and right sides of the inner wall of each fixing frame along its length direction, and several through grooves arranged in an array on the left and right sides of the upper end of the outer wall of each fixing frame.

[0008] Each pair of oppositely arranged sliding grooves is slidably connected to a placement rack that allows the fixed frame to be pulled out. Each fixed frame and each placement rack is made of thermally conductive material. An exhaust port is provided at the upper end of the outer wall of the thermally conductive frame, and an exhaust component is provided inside the exhaust port and extends out of the upper end of the outer wall of the insulation box. A temperature sensor is installed on one side of the upper end of the inner wall of the thermally conductive frame, and a control panel is provided on one side of the outer wall of the insulation box. The electric heater and the temperature sensor are both electrically connected to the control panel.

[0009] By adopting the above technical solution, when using the device, first power it on, operate the control panel to activate the electric heater, and the heat generated by the electric heater will be conducted through the heat-conducting frame to preheat the interior. During preheating, the heat on the heat-conducting frame will be transferred to the mounting bracket. After preheating, open the door, pull out the placement rack on the mounting bracket, place the corn silk tea to be dried on the placement rack and spread it out, then put the placement rack back into the mounting bracket, close the door, and operate the control panel to control the electric heater. At the same time, the temperature inside the heat-conducting frame can be controlled by a temperature sensor to prevent the temperature from being too high and affecting the drying process. The drying effect of corn silk tea is achieved by operating the control panel to activate the exhaust component in the exhaust port. This not only accelerates the airflow within the heat-conducting frame but also extracts the moisture generated during the drying process, improving the drying effect. The moisture and airflow at the bottom of the heat-conducting frame flow upwards through the slots on the mounting bracket. Since the mounting bracket is U-shaped, the heat from the upper part of the inner wall of the bracket can heat the corn silk tea in the corresponding placement rack. Simultaneously, the heat from the placement rack can also heat and dry the corn silk tea at the bottom, thereby improving the drying efficiency.

[0010] A further feature of this invention is that the placement frame includes a positioning frame, a placement net disposed at the bottom of the positioning frame and communicating with it, and sliding rods disposed on the left and right sides of the outer wall of the positioning frame and cooperating with the sliding groove.

[0011] A further feature of this invention is that the exhaust assembly includes an exhaust hopper that is tapered and wider at the bottom than at the top, and an exhaust fan installed on and connected to the lower end of the inner wall of the exhaust hopper.

[0012] By adopting the above technical solution, not only can the air flow inside the heat-conducting frame be accelerated, but the moisture generated during the drying of corn silk can also be extracted, thereby improving the drying effect of corn silk.

[0013] A further feature of this invention is that an electromagnetic valve is installed at the upper end of the exhaust hopper and communicates with it, and the electromagnetic valve is electrically connected to the control panel.

[0014] By adopting the above technical solution, the opening and closing of the exhaust port of the exhaust component can be controlled according to the actual situation during preheating and drying, so as to improve the drying effect of corn silk.

[0015] A further feature of this invention is that a mesh is provided on the left and right sides of the inner wall of the heat-conducting frame near its upper end.

[0016] By adopting the above technical solution, not only can the rate of heat loss within the heat-conducting frame be reduced during exhaust, but the suction force during exhaust can also be reduced to prevent dry corn silk from splashing.

[0017] In summary, this utility model has the following beneficial effects:

[0018] Firstly, this utility model can not only dry corn silk tea, but also keep it warm during the drying process. It can also dry a large amount of corn silk at once, which can improve work efficiency and reduce energy waste, thereby improving its applicability.

[0019] Secondly, the exhaust component of this utility model can not only accelerate the air flow in the heat-conducting frame, but also extract the water vapor produced during the drying of corn silk, thereby improving the drying effect of corn silk.

[0020] Thirdly, when drying corn silk, this utility model can make the corn silk heat more evenly by using a combination of a heat-conducting frame, a fixing frame and a placement frame, which can improve drying efficiency and reduce energy consumption. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Example, refer to Figure 1-4A corn silk tea drying device includes an insulated box 1 with an open front end, a door 11 hinged to and sealed to one side of the open end of the insulated box 1, a heat-conducting frame 13 with an open front end that is fitted to the inner wall of the insulated box 1, gaps between the outer wall of the heat-conducting frame 13 and the inner wall of the insulated box 1, and a sealed connection between the front end of the heat-conducting frame 13 and the front end of the inner wall of the insulated box 1. An electric heater 12 that fits to the inner wall of the insulated box 1 and contacts the outer wall of the heat-conducting frame 13 is installed on the left and right sides and the rear end of the inner wall of the insulated box 1. Multiple U-shaped fixing frames 14 are evenly distributed and arranged between the left and right sides of the inner wall of the heat-conducting frame 13 from bottom to top along its height direction. Each fixing frame 14 has a sliding groove 16 with opposite sides opened on the left and right sides of the inner wall of each fixing frame 14. Several through grooves 15 arranged in an array are opened on the left and right sides of the upper end of the outer wall of each fixing frame 14.

[0031] Each pair of oppositely arranged sliding grooves 16 is slidably connected to a placement rack 17 with a removable fixing frame 14. The placement rack 17 includes a positioning frame 18, a placement net 19 disposed at the bottom of the positioning frame 18 and communicating with it, and sliding rods 2 respectively disposed on the left and right sides of the outer wall of the positioning frame 18 and cooperating with the sliding grooves 16. Each fixing frame 14 and each placement rack 17 are made of heat-conducting material. An exhaust port 21 is provided at the upper end of the outer wall of the heat-conducting frame 13 and extends downward. An exhaust component is disposed in the exhaust port 21 and communicates with it, extending out of the upper end of the outer wall of the heat preservation box 1. 22. The exhaust assembly 22 includes an exhaust hopper 23 that is tapered and wider at the bottom than at the top, and an exhaust fan 24 that is installed on and connected to the lower end of the inner wall of the exhaust hopper 23. A solenoid valve 25 that is connected to the upper end of the exhaust hopper 23 is installed. A temperature sensor 27 is installed on one side of the upper end of the inner wall of the heat-conducting frame 13. A mesh 26 is installed on the left and right sides of the inner wall of the heat-conducting frame 13 near its upper end. A control panel 28 is installed on one side of the outer wall of the insulation box 1. The electric heater 12, the temperature sensor 27 and the solenoid valve 25 are all electrically connected to the control panel 28.

[0032] Usage: When using, first turn on the power to the device, operate the control panel 28 on the heat preservation box 1 to make the electric heater 12 work. The heat generated by the electric heater 12 is conducted through the heat conduction frame 13 to preheat the inside of the device. During preheating, the heat on the heat conduction frame 13 will be conducted to the fixing frame 14 and the placement rack 17. After preheating, open the box door 11 and pull the placement rack 17 out of the slide groove 16 on the fixing frame 14. Then, place the corn silk tea to be dried on the placement net 19 in the placement rack 17 and spread it flat. Then, put the placement rack 17 back into the slide groove 16 on the fixing frame 14 through the slide rod 2 on the positioning frame 18. Then close the box door 11 and operate the control panel 28 to control the electric heater 12 to work. At the same time, the temperature sensor 27 can control the temperature inside the heat conduction frame 13 to be within an appropriate range to avoid the temperature being too high and affecting the drying effect of the corn silk tea.

[0033] Simultaneously, the control panel 28 is operated to activate the exhaust component 22 in the exhaust port 21 and open the solenoid valve 25. The exhaust fan 24 in the exhaust hopper 23 is activated, which not only accelerates the airflow in the heat-conducting frame 13 but also extracts the moisture from the dried corn silk tea, improving the drying effect. During exhaust, the mesh 26 disperses the airflow and reduces its suction force, which not only prevents the dried corn silk tea from splashing due to the airflow but also slows down the heat loss to a certain extent. The moisture and airflow at the bottom of the heat-conducting frame 13 will flow upward through the through groove 15 on the fixing frame 14. Since the fixing frame 14 is U-shaped, the heat above the inner wall of the fixing frame 14 can heat the corn silk tea in the corresponding placement rack 17. At the same time, the heat on the placement rack 17 can also heat and dry the corn silk tea at the bottom, thereby improving the drying efficiency of the corn silk tea.

[0034] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment that make creative contributions as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
