Description

Technical Field

[0001] This invention belongs to the field of cardamom processing technology, specifically relating to a cardamom drying device with automatic loading and unloading functions. Background Technology

[0002] Cardamom is one of the major varieties of Chinese medicinal herbs used for both food and medicine, with the edible portion exceeding the medicinal portion. Cardamom is harvested in autumn when the fruits are ripe. After washing to remove impurities, it is sun-dried or low-temperature oven-dried. Oven-drying is used for long-term storage without damaging its nutritional components. The drying process removes a certain amount of moisture, increasing the concentration of soluble substances to a level that is difficult for microorganisms to utilize. During the drying process, the drying speed determines the quality of the dried product. The drying speed is related to the drying method and is influenced by factors such as the heating method, heating temperature, temperature and humidity of the medium, airflow speed, fruit variety, and state.

[0003] In existing technologies, the drying of cardamom after washing is generally accomplished using equipment such as drying ovens. However, existing drying ovens require manual loading and unloading of cardamom, resulting in low work efficiency. The drying time in drying ovens is long, and the center of the agglomerated material is not thoroughly dried, causing the overall product to fail to meet drying standards. To improve drying efficiency, the drying temperature of the oven can only be increased, which will change the quality of the product. Some material components will change or decrease due to excessively high temperatures, resulting in poor material quality. Summary of the Invention

[0004] To overcome the problems of low efficiency, long drying time, and incomplete drying of agglomerated materials in existing drying ovens, which require manual loading and unloading of cardamom, resulting in substandard product drying, and the need to increase oven temperature to improve efficiency, which alters product quality and reduces the composition of some materials, thus lowering the overall quality, this invention provides a cardamom drying device with automatic loading and unloading. The device uses a material lifting device for loading, and the drying chamber has a discharge port. During discharge, the material is conveyed and cooled before packaging. Compared to manual loading and unloading, this device improves work efficiency and reduces labor intensity and costs. The drying chamber is equipped with evenly spaced, inclined air distribution plates that create secondary air distribution cavities, allowing for multi-layered distribution of cardamom and effectively controlling the thickness of the cardamom layers. Furthermore, the multiple air distributions ensure uniform heating and drying during the subsequent blanching and drying processes, guaranteeing the quality of the cardamom processing.

[0024] To make the objectives, technical solutions, and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.

[0025] This invention discloses a cardamom drying device with automatic loading and unloading functions. The cardamom drying device mainly includes a drying chamber 1, a material lifting device 2, a conveying device 3, a steam boiler 4, a hot air boiler 5, and a condenser 6. The drying chamber 1 has a hot air duct 10 at its bottom. A perforated bottom plate 11 is inclined at the bottom of the drying chamber 1. A discharge port 12 is provided on the side wall of the drying chamber 1 on one side of the perforated bottom plate 11. A supporting mesh plate 13 is inclined above the perforated bottom plate 11 inside the drying chamber 1. An air distribution plate 14 is evenly inclined above the supporting mesh plate 13 inside the drying chamber 1. Material channels 15 are formed between the supporting mesh plate 13, the air distribution plate 14, and the inner wall of the drying chamber 1 on both sides. The top of the drying chamber 1 has a feed inlet 16 and an air outlet 17. A material intercepting baffle 18 is provided at the material channels formed between the supporting mesh plate 13 and the inner wall of the drying chamber 1 on both sides. A gate 19 is provided on the discharge port 12, and a cover plate 20 is provided on the feed inlet 16. The feed inlet 16 of the drying chamber 1 is connected to... At the end of the material lifting device 2, the conveying device 3 is connected to the discharge port 12. The steam boiler 4 and the hot air boiler 5 are respectively connected to the hot air pipe 10, and the condenser 6 is connected to the air outlet 17. The material is lifted by the material lifting device 2 for loading. The steam boiler 4 supplies high-temperature steam to blanch the fresh cardamom in the drying box 1. Then, the hot air boiler 5 supplies high-temperature air for drying. The condenser 6 condenses and dries the hot air during the blanching and drying process, effectively improving the drying effect. The drying box is equipped with a discharge port. When discharging, the material is conveyed and cooled by the conveying device before packaging. Compared with manual loading and unloading of cardamom, this method is beneficial to improving work efficiency and reducing labor intensity and labor costs. The drying box is equipped with inclined and uniform air distribution plates. The air distribution plates form a secondary air distribution cavity, which realizes the multi-layer distribution of cardamom and effectively controls the thickness of the cardamom stack. At the same time, the multiple air distribution by the air distribution plates ensures that the cardamom is heated and dried evenly during the blanching and drying process, thus ensuring the processing quality of cardamom.

[0026] The air distribution plate 14 is a hollow composite plate with an air distribution cavity in the middle. Air distribution holes 141 are evenly provided on the upper and lower side plates of the air distribution plate 14. By layering the air distribution plate, the thickness of the material layer is effectively reduced, which is conducive to the uniform passage of steam and hot air through the material layer. At the same time, the air distribution cavity can effectively redistribute the distribution of steam and hot air in various places, and redistribute the steam and hot air multiple times, which can effectively ensure that the steam and hot air pass through the material layer evenly, thereby improving the blanching and drying effect of the material.

[0027] The condenser 6 is connected to the steam boiler 4 and the hot air boiler 5 respectively.

[0028] The air distribution plates 14 are installed in the drying box 1 in a figure-eight structure in pairs. The two air distribution plates 14 form a material discharge channel 7. When the material cutting baffle 18 is closed, the material can be effectively filled through the material discharge channel 7 and the material channel 15 to ensure the filling effect.

[0029] The material channel formed between the two sides of the support mesh plate 13 and the inner wall of the drying box 1 is provided with an insertion port on the side wall of the drying box 1. The material cutting baffle 18 is inserted into the insertion port. The two ends of the material cutting baffle 18 are connected to the outer wall of the drying box 1 through telescopic cylinders. When it is necessary to discharge material, the material cutting baffle 18 is opened. The material discharge effect and complete discharge can be ensured through the discharge channel 7 and the material channel 15, avoiding residual material.

[0030] The discharge port 12 is provided with sliding grooves 191 on both sides. The gate 19 can be slidably installed in the sliding grooves 191. The two ends of the gate 19 are installed on the outer wall of the drying box 1 through telescopic cylinders. During the blanching and drying process, the gate 19 is kept closed to ensure the airtightness of the drying box 1, prevent steam and hot air leakage, and ensure the blanching and drying effect.

[0031] The feed inlet 16 is provided with support beams 161 on both sides, and a limiting groove 162 is provided on the inner side of the support beams 161. The cover plate 20 is slidably installed in the limiting groove 162. The cover plate 20 is installed on the support beams 161 through a multi-stage telescopic cylinder 163. During the blanching and drying process, the cover plate 20 is kept closed to ensure the airtightness of the drying box 1 and prevent steam and hot air leakage.

[0032] The material lifting device 2 includes an annular material bin 21, a chain conveyor assembly 22, and a lifting hopper 23. The chain conveyor assembly 22 is installed inside the annular material bin 21, and the lifting hoppers 23 are evenly installed on the chain conveyor assembly 22. The lifting hoppers 23 are located inside the annular material bin 21. The bottom of the annular material bin 21 is provided with a feeding port, and a feeding hopper 24 is installed on the feeding port. The top of the annular material bin 21 is provided with a discharge port, and a material chute 25 is provided on the discharge port. The lifting hoppers 23 are driven by the chain conveyor assembly 22 to circulate within the annular material bin 21, thereby lifting the material from the bottom to the top, realizing material lifting, automatic feeding, and filling.

[0033] The annular material bin 21 is provided with slide rails 26 on both sides. The chain conveyor assembly 22 is equipped with rollers 27 on its side via short shafts. The rollers 27 are limited and installed in the slide rails 26. The chain conveyor assembly 22 is supported by the rollers 27 and the slide rails 26 to ensure the smooth operation of the lifting hopper 23.

[0034] The outer wall of the drying oven 1 is a hollow double-layer structure, and the hollow space is filled with a heat-insulating structure.

[0035] Work process: When loading materials, with the material cut-off baffle 18 closed, the material is lifted by the material lifting device 2 for loading. The material can be effectively loaded through the discharge channel 7 and the material channel 15, ensuring loading efficiency. The gate 19 and cover 20 are closed to ensure the airtightness of the drying chamber 1 and prevent steam and hot air leakage. High-temperature steam is supplied by the steam boiler 4 to blanch the fresh cardamom in the drying chamber 1. High-temperature air is then supplied by the hot air boiler 5 for drying. The condenser 6 condenses and dries the hot air during blanching and drying, effectively improving the drying effect. When discharging materials, the gate 19 and the material cut-off baffle 18 are opened. The baffle 18, through the feeding channel 7 and the material channel 15, ensures the effective and complete discharge of materials, avoiding any residual materials. During discharge, the materials are conveyed and cooled by a conveying device before packaging. Compared with manual filling and removal of cardamom, this method improves work efficiency and reduces labor intensity and labor costs. The drying box is equipped with evenly inclined air distribution plates, which form secondary air distribution cavities to achieve multi-layer distribution of cardamom, effectively controlling the thickness of the cardamom stack. At the same time, the multiple air distributions by the air distribution plates ensure uniform heating and drying of the cardamom during the subsequent blanching and drying processes, thus guaranteeing the processing quality of the cardamom.

[0036] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of the present invention.
