Description
Technical Field
[0001] This utility model relates to the field of food drying equipment technology, specifically a burdock drying equipment with residual heat recovery. Background Technology
[0002] Burdock, also known as burdock, is a biennial herbaceous plant belonging to the genus Arctium in the family Asteraceae. It has both edible and medicinal value. As a plant with both medicinal and edible properties, the drying process is crucial in its processing. Fresh burdock has a high water content and is prone to spoilage. Drying significantly reduces the moisture content, extends its shelf life, and facilitates long-term storage and transportation. By controlling the temperature and humidity during the drying process, problems such as discoloration and cracking can be avoided, ensuring the consistency of the product's appearance and taste. Therefore, compared with traditional sun-drying methods, modern drying technology consumes less energy, is more efficient, and is not affected by weather, making it more suitable for large-scale production.
[0003] When used for burdock drying, commonly used drying equipment includes heat pump dryers and continuous dryers. In production lines, continuous dryers are often used due to the large material flow rate. A conveyor belt is used to continuously feed the burdock raw material into the drying channel, and the drying process is achieved by exhausting hot air.
[0004] When the aforementioned drying equipment heat-dries burdock, the internal moisture of the burdock evaporates to generate high-temperature steam when heated, which is discharged through the exhaust port structure. At the same time, the hot air of the drying device is continuously discharged into the drying channel through fans and other devices. Some of the heat cannot be used in the drying process and is discharged with the steam through the exhaust port, resulting in a large waste of waste heat resources. To address this, we propose a burdock drying equipment with waste heat recovery. Utility Model Content
[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0006] The purpose of this invention is to provide a burdock drying device with residual heat recovery to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a burdock drying device with residual heat recovery, comprising an outer frame, a conveying mechanism connected inside the outer frame, a liquid storage frame connected to the bottom of the inner part of the outer frame, the outer frame including an outer shell, a control panel provided on one side of the outer wall of the outer shell, a pressure gauge provided on one side of the control panel, a heat pump dryer fixed to one end of the outer wall of the outer shell, a fan connected to one side of the heat pump dryer, a drying chamber connected to one side of the fan, heating pipes distributed at the top of the drying chamber, and a steam exhaust valve connected to the top of the heating pipes.
[0008] Furthermore, the top of the drying chamber is inclined, and the heating pipes are distributed along the top of the drying chamber and pass through both ends of the outer casing frame.

[0011] Furthermore, the two sides of the conveyor frame are fixedly connected to the inner walls of the drying chamber via brackets, and the chain mesh belt forms a transmission structure with the conveyor frame via a motor-driven roller.

[0013] Furthermore, the liquid storage seat is fixedly connected to the liquid storage cavity by a tripod, and the tripod is arranged at equal intervals along the top surfaces of both sides of the liquid storage seat.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This drying equipment uses a heat pump dryer connected to one end of the outer frame, along with a built-in fan, to input heat energy. It works in conjunction with a conveying mechanism to continuously dry burdock raw materials. During the process, the high temperature generated in the drying chamber is absorbed by the distributed heating pipes.

[0027] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0028] This utility model provides, for example Figure 1-4 The burdock drying equipment with residual heat recovery shown includes an outer frame 1, a conveying mechanism 2 connected inside the outer frame 1, a liquid storage frame 3 connected to the bottom inside the outer frame 1, an outer shell 101, a control panel 102 provided on one side of the outer wall of the outer shell 101, a pressure gauge 103 provided on one side of the control panel 102, a heat pump dryer 104 fixed on one end of the outer wall of the outer shell 101, a fan 105 connected to one side of the heat pump dryer 104, a drying chamber 106 connected to one side of the fan 105, a heating pipe 107 distributed at the top of the drying chamber 106, and a steam exhaust valve 108 connected to the top of the heating pipe 107.
[0029] To ensure effective preheating utilization in the drying process and reduce waste of thermal energy resources, such as Figure 1-2 As shown, this drying equipment uses a heat pump dryer 104 connected to one end of the outer frame 101, in conjunction with a built-in fan 105, to input heat energy. It works with the conveying mechanism 2 to continuously dry the burdock raw material. During the process, the high temperature generated in the drying chamber 106 is absorbed by the distributed and penetrating heating pipes 107. The heat can be absorbed by the medium in the heating pipes 107, such as industrial water, to form warm water for use, thus achieving the effect of residual heat recovery. The inclined structure at the top of the drying chamber 106 can condense the water vapor rising from the burdock raw material during drying and then slide it down to the liquid storage frame 3 at the bottom of the inner wall for collection, which is convenient for subsequent collection, cleaning and reuse.
[0030] During the drying process, the internal high temperature and steam pressure of the drying chamber 106 can be monitored by the pressure gauge 103 connected to one side to ensure stability. When the pressure is too high, the steam venting valve 108 connected to the top can be opened in time to vent steam and relieve pressure, thereby improving safety.
[0031] like Figure 3 As shown, the conveying mechanism 2 includes a conveying frame 201, and supports 202 are connected to the outer walls of both sides of the conveying frame 201. One side of the supports 202 is fixed to the inner wall of the drying chamber 106. Chain mesh belts 203 are provided inside both sides of the conveying frame 201, and motor drive rollers 204 are connected to both ends of the chain mesh belts 203.
[0032] To further improve the stability of the continuous drying process of this drying equipment, such as Figure 3As shown, the drying equipment has a conveyor frame 201 fixed on both sides of the inner wall of the outer shell frame 101 by a bracket 202. During continuous drying, the burdock raw material can be stably and continuously transported by the motor-driven roller 204 driving the chain mesh belt 203, thereby maintaining the continuity and stability of the heating process.
[0033] like Figure 4 As shown, the liquid storage frame 3 includes a liquid storage base 301, and a tripod 302 is connected to both sides of the top of the liquid storage base 301. A liquid storage cavity 303 is opened inside the liquid storage base 301. The top of the liquid storage cavity 303 is connected to the drying cavity 106, and a drain valve 304 is connected to both ends of the liquid storage cavity 303.
[0034] Finally, to facilitate subsequent cleanup and collection and reuse of the waste liquid, such as Figure 4 As shown, this drying equipment has a liquid storage seat 301 connected to the bottom of the drying chamber 106. The condensed steam water that slides down can be collected through the liquid storage chamber 303 opened in the liquid storage seat 301 and then discharged through the drain valves 304 on both sides.
[0035] In summary, when using this drying equipment, the user first places the burdock raw material to be dried onto the chain conveyor belt 203 inside the conveyor frame 201. Driven by the motor of the motor-driven roller 204, the chain conveyor belt 203 is driven, transporting the burdock raw material into the drying chamber 106 of the outer shell frame 101. The heat pump dryer 104 needs to be turned on beforehand, and the fan 105 connected to the heat pump dryer 104 preheats the chamber. Once the burdock raw material enters the drying chamber 106, it undergoes drying. The high temperature generated inside will then be absorbed by the heat pump dryer. The heating pipe 107 conducts heat, and the heat is absorbed and heated through the circulating medium inside the heating pipe 107 to complete the waste heat recovery. The heating pipe 107 needs to be connected to the circulating water pipe to maintain the circulation process of heating and preheating recovery. In the inclined structure at the top of the drying chamber 106, the water vapor rising from the burdock raw material after drying can be condensed through the inclined structure and slowly slide down to the inner walls on both sides. Then, it flows through the inner walls to the liquid storage frame 3 at the bottom for collection. Subsequently, it can be discharged and treated by opening the drain valves 304 on both sides, and the collected liquid can be collected, cleaned, and used.
[0036] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
