Description

Technical Field

[0001] This utility model relates to a drying technology, specifically a continuous intelligent drying equipment for agricultural and sideline products. Background Technology

[0002] Agricultural and sideline products refer to primary products produced during agricultural production, namely, unprocessed or only partially processed products obtained directly from crop farming, animal husbandry, and fisheries. These products include, but are not limited to, grains, beans, vegetables, fruits, meat, poultry eggs, aquatic products, and the harvested products of various cash crops. Continuous intelligent drying equipment for agricultural and sideline products is a modern agricultural processing equipment specifically designed for the efficient and uniform drying of agricultural and sideline products, thereby better preserving their quality and nutritional components.

[0003] In traditional continuous intelligent drying equipment, the bottom cavity adopts an integral structure, and hot air is blown from one end to the other. After being folded back by the front plate of the equipment, it enters the upper drying mesh belt. This design results in a single and concentrated flow path of hot air in the cavity, which cannot evenly cover the entire material area. Due to the large cavity area, the energy of the hot air gradually decreases during transmission, especially in areas far from the hot air inlet, where the intensity of the hot air is significantly weakened. This means that some materials cannot come into contact with enough hot air. This uneven distribution of hot air means that some materials can be fully dried, while others are under-dried due to insufficient heat, resulting in uneven drying. Uneven heating of materials not only leads to poor drying effect but also results in inconsistent product quality. Utility Model Content

[0011] A lifting frame is provided, and a material feeding device is provided on the lifting frame. A power source for driving the material feeding device is installed on the lifting frame.

[0012] The lifting mesh belt is driven on the lifting frame, and the lifting frame on both sides of the lifting mesh belt is provided with first material-stopping edges to prevent materials from falling during the lifting process.

[0017] A cavity frame, on which a fixed door is provided, and a movable door is adapted to be installed on the cavity frame located on one side of the fixed door, and a second wind baffle is provided on the cavity frame on one side of the movable door.

[0018] A drying mesh belt is installed on the cavity frame in several places. Each of the drying mesh belts has a second baffle on both sides to prevent material from falling during the drying process. The top of the cavity frame is equipped with a dehumidification duct for discharging humid air.

[0019] As described above, a continuous intelligent drying equipment for agricultural and sideline products includes the following active device:

[0020] An active frame, wherein a second drive motor is mounted on the top of the active frame, and the second drive motor is connected to the ends of a second active shaft and a second passive shaft provided on the active frame via a drive belt;

[0021] The second material guiding device is installed on the active frame. The bottom of the active frame is provided with a third baffle to prevent hot air leakage. The active frame is also equipped with a second sprocket cover that shields the transmission belt.

[0022] The above-mentioned continuous intelligent drying equipment for agricultural and sideline products includes a hot air circulation device comprising:

[0023] A circulating fan, one side of which is connected to a circulating air duct, is used to blow external air to a steam radiator and generate hot air through heat exchange via the steam radiator.

[0029] By dividing the hot air circulation device into multiple independent units, each equipped with an independent steam radiator and circulating fan, these independent units are staggered on both sides of the cavity device. Each group of hot air circulation devices is separated by a baffle plate to ensure that the hot air circulation on both sides does not interfere with each other. This design allows the hot air to be evenly distributed in the cavity, avoiding the problem of hot air being concentrated in a certain area in traditional equipment.

[0030] The baffle plate further optimizes the flow path of hot air. It can not only effectively separate the hot air from different units and prevent the hot air from flowing turbulently in the cavity, but also guide the hot air to penetrate each layer of drying mesh belt evenly. In this way, the material can come into uniform contact with the hot air during the drying process, thereby achieving uniform drying of the material. This uniform hot air distribution not only improves drying efficiency, but also significantly improves the consistency of material quality and reduces the defect rate caused by uneven drying.

[0046] Hot air circulation device 5, which includes a steam control system 7 and a condensate drainage system 8, is provided in several staggered positions on both sides of the cavity device 3 for blowing hot air onto the material. Each group of hot air circulation devices 5 is separated by a baffle plate, and the hot air circulation devices 5 on both sides do not interfere with each other.

[0047] The discharge conveying device 6 is installed on the active device 4 and is used to convey the dried material to the outside of the equipment.

[0048] In this embodiment, the lifting device 1 serves as the initial processing unit for materials, which can lift the pile of materials to a certain height and ensure that the materials are evenly distributed when entering the cavity device 3, laying the foundation for the subsequent drying process. The cavity device 3 serves as the core drying area, with the passive device 2 and active device 4 set at both ends working together to ensure the smooth transport and orderly turnover of materials in the cavity.

[0049] The hot air circulation device 5 is a key component for achieving efficient drying. It ensures that hot air can evenly cover the entire material area, avoiding the problem of uneven hot air distribution commonly found in traditional drying equipment. Through the precise control of the steam control system 7 and the effective cooperation of the condensate drainage system 8, the hot air circulation device 5 can continuously and stably provide hot air at a suitable temperature, while effectively removing steam condensate, ensuring the stability of the drying process, improving drying efficiency, and significantly reducing energy consumption and operating costs. The discharge conveying device 6 is responsible for smoothly and efficiently transporting the dried material to the outside of the equipment, ensuring the continuity and automation of the entire drying process.

It is used to carry and transport materials. Each drying mesh belt 305 has a second baffle 306 on both sides. This design can effectively prevent materials from falling due to vibration or airflow during the drying process and ensure the stability of materials throughout the drying process. In addition, a dehumidification duct 307 is installed on the top of the cavity frame 301 to exhaust the humid air generated during the drying process and prevent moisture from accumulating in the cavity, thereby ensuring the uniformity and efficiency of the drying effect.
