Description
Technical Field
[0001] The invention relates to the technical field of seasoning packaging, in particular to an energy-saving dehydrated vegetable drying device. Background Art
[0002] In the field of dehydrated vegetable processing, traditional drying equipment mostly relies on electric heating or fossil fuel heating to dehydrate vegetables in a single high-temperature environment. Such equipment needs to continuously consume a large amount of energy during operation, especially in large-scale production, where energy costs account for a high proportion. At the same time, due to the lack of an effective waste heat recovery mechanism, the hot and humid air discharged during the drying process is directly discharged, resulting in a large amount of sensible heat waste, further exacerbating the energy consumption problem. In addition, traditional devices mostly adopt a single-stage drying mode. The high-temperature environment not only easily destroys the nutrients and color in the vegetables, but may also cause product quality differences due to uneven dehydration, making it difficult to meet the production needs of high-quality dehydrated vegetables.
[0003] Currently, the dehydrated vegetable drying devices on the market generally have structural design defects. On the one hand, the drying process lacks gradient control and cannot dynamically adjust the drying parameters according to the moisture content of the vegetables. The high temperature stage easily leads to excessive dehydration of the vegetable surface and residual moisture inside. The low temperature stage prolongs the drying time due to insufficient energy supply. On the other hand, traditional devices lack an efficient air treatment system. The hot and humid air is directly discharged without filtration and dehumidification, which not only pollutes the environment but also wastes heat energy. The debris in the air can easily clog the air duct, affecting the stability of the equipment operation. In addition, manual cleaning and maintenance are frequently required, which not only increases costs, but may also reduce production efficiency due to downtime for maintenance, making it difficult to adapt to the needs of automated production lines.
[0004] In response to the problems of high energy consumption, insufficient quality assurance and difficult maintenance in traditional drying devices, the present invention proposes an energy-saving dehydrated vegetable drying device. By integrating a solar power supply system and waste heat recovery technology, light energy is converted into electrical energy and stored. At the same time, the hot and humid air discharged from the heating box is filtered and dehumidified through a rotating filter and a rotary dehumidifier, realizing the recycling of heat energy.

The gradient drying structure of the heating box and the air drying box is the core innovation. The high-temperature hot air in the heating box quickly dehydrates wet vegetables. When the moisture content of the vegetables drops to an appropriate range, the transmission belt transfers them to the air drying box. The hot and humid air discharged from the heating box is filtered, dehumidified, and heated again for gentle drying. This design not only improves dehydration efficiency through the high-temperature stage, but also uses the low-temperature waste heat stage to avoid nutrient loss, color deterioration, and over-drying of vegetables caused by continuous high temperature, thereby ensuring product quality consistency.
[0015] 2. The waste heat recovery system uses the coordinated operation of the rotary filter and the rotary dehumidifier to filter out debris from the hot and humid air discharged from the heating box. The hot and humid air then passes through the rotary dehumidifier's processing fan and regeneration fan to complete water vapor condensation and secondary air heating, allowing the dry hot air to re-enter the air drying box, significantly improving thermal energy utilization and reducing sensible heat waste. In the automatic cleaning component, the cleaning fixed plate at the bottom of the heating box rotates cyclically to clean debris, and the rotating filter in the filter cleaning box cooperates with the fixed brush to continuously remove impurities in the air. The debris collection tank facilitates centralized processing, reducing manual maintenance requirements and ensuring long-term stable operation of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The remaining structures are the same as those of Example 3.
[0029] Working principle of the present invention: In the first step, the energy-saving fixing plate 9 on the fixed base plate 1 is installed with a solar panel 10, which converts light energy into electrical energy and stores it in an integrated heat-insulating storage box 11 to power the entire system. After the system is started, the centrifugal fan 8 is connected to the heating box 7 through the heating connecting plate 6, and the external air or the warm air discharged from the waste heat hot air outlet 20 of the air drying box 5 is sucked in. The heating resistance wire inside the heating box 7 heats the air to form high-temperature hot air.
[0030] In the second step, hot air is blown into the heating box 2 through the heating connecting plate 6. The wet vegetables are placed on the transmission belt 35 in the heating box 2 and slowly move forward with the belt body. The high-temperature hot air quickly dehydrates the vegetables, which is the main moisture removal stage.
[0031] In the third step, the cleaning fixed plate 16 on the inside of the heating box 2 is sleeved on the rotating stud 15, and the servo motor 14 drives the rotating stud 15 to rotate, driving the cleaning fixed plate 16 to circulate in the guide constraint groove 12. The cleaning fixed plate 16 fits the bottom end of the heating box 2 and sweeps the dust and dehydrated vegetable debris blown in by the fan to the connection between the heating box 2 and the air drying box 5. The debris is sucked into the inside of the filter cleaning box 3 through the hot and humid air outlet 17.
[0032] In the fourth step, the hot and humid air enters the filter cleaning box 3 from the hot and humid air outlet 17 through the installation slot 21. The rotating filter 31 continues to rotate under the engagement drive of the rotating gear column 25 and the flexible annular strip 30. The fixed brush 23 adheres to the surface of the filter to clean the debris, and the debris falls into the debris collection slot 29 below.
[0033] In the fifth step, the air intake 18 of the rotary dehumidifier 4 inhales the filtered hot and humid air from the filter cleaning box 3. A processing fan and a regeneration fan are provided inside the rotary dehumidifier 4. The processing fan dries the internal components of the rotary dehumidifier 4 after the moisture is adsorbed. When the hot and humid air is cooled, the water vapor condenses and the temperature of the hot air decreases. The regeneration fan reheats the cooled air. The heated dry hot air is sent into the air drying box 5 through the dry hot air outlet 19.
[0034] In the sixth step, the warm dry air that has been dehumidified and heated twice enters the air drying box 5, and the moisture content of the vegetables drops below 50%. The vegetables are transferred from the heating box 2 to the air drying box 5 through the transmission belt 35, and the low-temperature hot air is used for gentle secondary drying to prevent high temperature from damaging the nutrition and color of the vegetables.
[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
