Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of low-temperature drying ovens, and more specifically, relates to a layered konjac low-temperature drying oven. Background Art
[0002] As an important cash crop, konjac is rich in functional components such as glucomannan and has wide applications in the fields of food, medicine, chemical engineering, etc. During the processing of konjac, drying is one of the key links. Low-temperature drying can maximize the retention of the nutritional components and functional characteristics of konjac and avoid damage to its quality caused by high temperatures. Therefore, the konjac low-temperature drying oven plays an important role in the konjac processing industry. Traditional konjac low-temperature drying ovens usually adopt a fixed layered structure with a fixed spacing between the internal drying racks, which cannot be flexibly adjusted according to the actual size and stacking thickness of konjac. When drying konjac with a large volume or thick stacking, due to the insufficient spacing between the drying racks, the ventilation between konjac is poor, resulting in uneven heat transfer. Some konjac is not fully dried, while some konjac may be charred due to local overheating, seriously affecting the drying quality and yield of konjac. On the contrary, when drying konjac with a small volume or thin stacking, the drying racks with fixed spacing will cause waste of space, reduce the use efficiency of the drying oven, and increase the unit energy consumption.
[0003] In addition, the structural design of the drying racks of traditional drying ovens is not reasonable enough. Some drying racks adopt a solid plate structure, and hot air is difficult to penetrate. Konjac can only be heated on one side, and it needs to be frequently turned manually to achieve uniform drying, which not only increases the labor intensity but also easily damages konjac during the turning process, affecting the product quality. At the same time, the hot air circulation system design of traditional drying ovens is not scientific enough. The hot air is unevenly distributed in the oven, and there are air flow dead ends, resulting in inconsistent drying speeds of konjac, prolonging the overall drying time, and reducing the production efficiency. In terms of the operation and maintenance of the equipment, there are also many problems with traditional konjac low-temperature drying ovens. The installation and disassembly of its drying racks are inconvenient, and the adjustment process is complex. It needs to be operated with the help of professional tools and technicians, increasing the use and maintenance costs of the equipment. Moreover, the sealing and heat insulation performance of the drying oven is poor, and the heat dissipation is serious, which not only causes energy waste but also may lead to unstable temperature inside the oven, affecting the drying effect. The support structure of the drying oven is usually of a fixed height and cannot adapt to different ground conditions. When placed on an uneven ground, the drying racks are prone to tilt, resulting in uneven distribution of konjac and further affecting the drying quality. Summary of the Invention
[0004] In view of this, a layered konjac low-temperature drying oven provided by the present invention solves the technical problem of uneven drying caused by the fixed spacing of the drying racks of traditional konjac low-temperature drying ovens and improves the drying efficiency.

[0023] The beneficial effects of adopting the above-mentioned improved scheme are: the cooperation between the guide protrusion and the guide groove provides precise guidance for the movement of the drying rack in the slot, making the movement of the drying rack more stable and smooth, avoiding the drying rack from tilting or jamming during movement, and improving the efficiency and accuracy of the spacing adjustment.
[0024] Furthermore, an openable and closable door is provided on the front of the drying box body, and an observation window is provided on the door, and the observation window is made of transparent tempered glass.

[0027] In terms of drying quality, through the adjustable spacing of the drying racks, the space can be flexibly adjusted according to the actual situation of konjac to ensure that there is enough space for konjac during the drying process, avoiding uneven drying caused by cramped space. Whether drying konjac with a large volume and thick accumulation or small and thin konjac, it can ensure uniform circulation of hot air, enabling all parts of the konjac to be evenly heated, effectively avoiding local overheating or insufficient drying, thereby significantly improving the drying quality and yield rate of konjac. At the same time, the mesh bearing plate and reasonable hot air circulation design further promote heat transfer and water evaporation, enabling konjac to be dried evenly and efficiently, improving the product quality;
[0028] In terms of production efficiency, on the one hand, the flexible adjustment function of the drying rack spacing reduces the problem of extended drying time caused by unreasonable space, and can quickly adjust the drying conditions according to the characteristics of konjac, increasing the drying amount per unit time. On the other hand, the recycling of hot air and the reasonable air duct design enable hot air to fully contact konjac, accelerating the water evaporation speed and shortening the overall drying time. In addition, convenient operation structures such as an openable box door and easily adjustable drying racks reduce the time for loading and unloading konjac and equipment adjustment, improving the efficiency of production operations, thereby significantly enhancing the overall production efficiency of the drying box and meeting the needs of large-scale production of enterprises;
[0029] In terms of equipment versatility and applicability, the design of adjustable spacing enables the drying box to adapt to the drying requirements of konjac with different sizes, shapes, and stacking thicknesses. Whether dealing with different varieties of konjac or meeting the requirements of different production batches, it can easily cope, greatly improving the versatility of the equipment. At the same time, the structural design of the equipment takes into account various actual application scenarios, such as adjustable-height support feet to adapt to different ground conditions, and an openable box door for easy operation and maintenance, enhancing the applicability of the equipment in various environments and expanding the application range of the equipment.

[0054] Specifically, the principle of the present invention is:
[0055] Regarding the adjustment of the distance between the drying racks, multiple groups of vertically arranged card slots provided on the inner walls on both sides of the drying box body, together with the drying racks and adjusting bolts, constitute an adjustable structure. The card slots are in the shape of long grooves and the groove walls are provided with internal threads. After the two ends of the drying rack are inserted into the card slots, the adjusting bolts pass through the through holes on the drying rack and are threadedly connected to the internal threads of the card slots. According to the principle of screw drive, when a tool is used to rotate the adjusting bolt, due to the meshing of the threads, the drying rack will move precisely in the vertical direction within the card slots. By controlling the number of turns and direction of rotation of the adjusting bolt, the distance between each layer of drying racks can be accurately adjusted, so as to meet the drying requirements of konjac of different sizes and stacking thicknesses. This structural design is simple and reliable, and the operation is convenient. Without complex mechanical structures or control systems, the distance between the drying racks can be flexibly adjusted;
[0056] For the hot air circulation system, the drying box adopts a design method of inlet air from the top and outlet air from the bottom. After the hot air enters the drying box from the hot air inlet at the top, it flows downward in the box and passes through the konjac on each layer of drying racks. Since the drying rack adopts a mesh bearing plate structure and the mesh holes are in the shape of diamonds or squares, this design is conducive to the uniform penetration of the hot air, enabling each part of the konjac to fully contact the hot air and ensuring the uniformity of heat transfer. After the hot air exchanges heat with the konjac, it carries moisture and is discharged from the hot air outlet at the bottom, enters the external hot air circulation system for treatment, and after heating, dehumidification and other processes, it enters the drying box from the hot air inlet again to realize the recycling of the hot air. This hot air circulation method not only improves the energy utilization efficiency, reduces the drying cost, but also maintains a stable temperature and humidity environment inside the drying box, ensuring that the konjac is dried under suitable conditions;
[0057] Scientific design principles also contribute to the equipment's stability and ease of use. Guide protrusions on each end of the drying rack mate with guide grooves in the slot walls, providing precise guidance during movement, ensuring smooth movement and preventing tilting or jamming. The adjusting bolt heads are larger than the diameter of the drying rack's through-holes to prevent the bolts from falling out and ensure a secure connection between the drying rack and the slots. The insulation on the side walls of the drying oven effectively blocks heat loss, reducing energy consumption while preventing overheating of the outer wall and ensuring operator safety. The height-adjustable support legs, threaded into the adjustment sleeves via threaded studs, allow for flexible adjustment of the drying oven's height according to floor conditions, maintaining a level surface and ensuring even distribution of the konjac on the drying rack for uniform drying. The retractable door is connected to the drying oven body via hinges or hinges. A locking mechanism and sealing strips ensure ease of operation while ensuring a tight seal, minimizing hot air leakage and external interference.
