Description

Technical Field

[0001] The invention relates to the technical field of dried vegetable production, in particular to an automatic drying device for drying vegetables. Background Art

[0002] In the field of dried vegetable processing, the drying process is a key link that affects the quality and production efficiency of dried vegetables. Currently, the common methods for drying dried vegetables on the market are mainly natural air drying and sun drying. Although this traditional method has the advantage of low cost, it has significant disadvantages. On the one hand, it is heavily dependent on weather conditions. In the event of inclement weather such as rainy, humid, etc., the drying process cannot proceed normally, which greatly limits the continuity and stability of production. On the other hand, long-term natural drying is not only time-consuming, but also causes the dried vegetables to be exposed to the external environment for a long time, which makes them easily contaminated with pollutants such as dust and microorganisms, making food safety difficult to guarantee. Moreover, natural drying cannot ensure that every piece of dried vegetable can receive sunlight and wind evenly, resulting in inconsistent drying levels and uneven product quality.

[0003] With technological advancements, oven drying has gradually become used in the production of dried vegetables. However, existing oven equipment has numerous drawbacks. During operation, the air inside and outside the oven continuously exchanges air, dissipating a significant amount of heat. This results in significant energy waste and high drying costs. Furthermore, the airflow within the oven is often not optimal, making it difficult to achieve uniform, all-around drying of large vegetables, such as whole carrots. This results in significant variations in the taste of dried vegetables, failing to meet consumer demand for high-quality dried vegetables. Summary of the Invention

[0039] A partition box 101 is provided in the housing 1, which divides the housing 1 into a front chamber 104 and a rear chamber 102. A sealing door 105 is provided on the front face of the housing 1. A controller for controlling the speed of the motor 301 and the temperature of the heating wire 202 is provided on the housing 1.

[0041] The wind circulation mechanism 4 includes an upper air guide cover 401, a lower air guide cover 403, a connecting pipe 402, a first fan 404, and a second fan 405. The upper air guide cover 401 is fixedly mounted on the upper end surface of the casing 1, and the lower air guide cover 403 is fixedly mounted on the lower end surface of the casing 1. The upper air guide cover 401 and the lower air guide cover 403 are connected through the connecting pipe 402. The first fan 404 is mounted in the lower air guide cover 403, and the second fan 405 is mounted in the upper air guide cover 401.

[0042] The dried vegetable tumbling mechanism 3 includes a motor 301, a rotating drum 302, an inner container 303, a spiral scraper 304 and a transmission frame 305. The dried vegetable tumbling mechanism 3 is installed in the heating mechanism 2.

[0043] The gas-liquid separator 5 includes a housing 501 , a reflective tube 502 and a filter 504 . The gas-liquid separator 5 is fixedly mounted on the connecting pipe 402 .

[0044] Furthermore, the lower air guide cover 403 is connected to the rear chamber 102, the upper air guide cover 401 is connected to the front chamber 104, the heat conduction plate 201 is fixedly installed on the partition box 101, and the first axial hole 2011 that is connected to the front chamber 104 and the rear chamber 102 is evenly arranged on the heat conduction plate 201, and the dried vegetable rolling mechanism 3 is movably installed in the first axial hole 2011.

[0045] Air is blown from the rear chamber 102 by the first fan 404, and air is extracted from the front chamber 104 by the second fan 405, so that the air flow passes through the first axial hole 2011 from the rear chamber 102 and enters the front chamber 104, thereby drying the dried vegetables in the dried vegetable tumbling mechanism 3. The wind circulation mechanism 4 circulates the air in the casing 1 to the gas-liquid separator 5, thereby separating the moisture in the humid air and gradually reducing the humidity in the chassis.

[0046] Furthermore, the rotating drum 302 passes through the first axial hole 2011 and is rotatably connected to the heat conduction plate 201. The motor 301 is fixedly mounted on the partition box 101. A drive shaft 306 is fixedly mounted on the output shaft of the motor 301. A transmission shaft 307 rotatably connected to the casing 1 is provided at the bottom lower end of the rotating drum 302. A fourth toothed umbrella 3061 is provided on the drive shaft 306. A fifth toothed umbrella 3071 meshing with the fourth toothed umbrella 3061 is provided on the transmission shaft 307. A worm 3072 is provided on the transmission shaft 307. A worm wheel 3021 cooperating with the worm 3072 is fixedly mounted on the outer end of the rotating drum 302.

[0047] The motor 301 drives the drive shaft 306 to rotate, and drives the transmission shaft 307 to rotate through the cooperation of the fourth gear umbrella 3061 and the fifth gear umbrella 3071. The transmission shaft 307 drives each rotating drum 302 through the worm gear 3021 and the worm 3072, thereby driving the dried vegetables to rotate, causing the dried vegetables to roll in the inner pot 303, so that the dried vegetables are evenly heated, avoiding unilateral heating of the dried vegetables, resulting in uneven heating of the dried vegetables and affecting the quality of the dried vegetables.

[0048] Furthermore, a rectangular ridge 3031 is provided on the outer side of the inner liner 303, and a strip groove 3023 that slides with the rectangular ridge 3031 is provided on the inner end face of the rotating drum 302. The inner liner 303 is inserted into the rotating drum 302 and is slidably connected thereto. A second axial hole 3032 is provided at the bottom of the inner liner 303, and a first rotating shaft 3041 is provided at the bottom of the spiral scraper 304. The first rotating shaft 3041 passes through the second axial hole 3032 and is movably connected to the inner liner 303. The scraper is a spiral structure, and the outer end face of the scraper is in sliding contact with the inner end face of the inner liner 303. The edges of the double spiral scraper 304 are chamfered.

[0049] The rectangular ridge 3031 cooperates with the strip groove 3023 so that the inner pot 303 can be removed from the drum 302, and the drum 302 can drive the inner pot 303 to rotate, and the rectangular ridge 3031 structure increases the contact area between the inner pot 303 and the drum 302, so that the heating mechanism 2 can heat the inner pot 303 more quickly. Through the cooperation of the first rotating shaft 3041 and the second shaft hole 3032, the double spiral scraper can be taken out from the inner pot 303 and can be rotated around the first rotating shaft 3041 in the inner pot 303 after installation. The sliding connection structure of the inner pot 303 and the spiral scraper 304 enables the inner pot 303 and the spiral scraper 304 to be removed for cleaning after production is completed, thereby improving the convenience of equipment cleaning and ensuring food safety.

[0050] Furthermore, the transmission frame 305 is fixedly mounted on the heat conducting plate 201, and a second rotating shaft 3051 and a sleeve 3052 are provided on the transmission frame 305. The outer end surface of the rotating cylinder 302 is provided with a fixedly connected first toothed umbrella 3022, and the outer end of the sleeve 3052 is provided with a fixedly connected third toothed umbrella 3054. The sleeve 3052 is rotatably connected to the transmission frame 305, and a second toothed umbrella 3053 engaged with the first toothed umbrella 3022 and the third toothed umbrella 3054 is provided on the second rotating shaft 3051. The first rotating shaft 3041 is detachably mounted in the sleeve 3052.

[0051] When the drum 302 rotates, the first tooth umbrella 3022, the second tooth umbrella 3053 and the third tooth umbrella 3054 cooperate to drive the sleeve 3052 to rotate in the opposite direction, so that the sleeve 3052 cooperates with the first rotating shaft 3041 to make the double spiral scraper 304 and the inner tank 303 rotate in the opposite direction. The scraper scrapes off the condensed water and impurities on the inner wall of the inner tank 303, so that they are discharged into the guide groove 106 in time for removal, and at the same time, the dried vegetables are intermittently separated from the inner wall of the inner tank 303 to avoid continuous contact between the dried vegetables and the inner wall. After drying, the dried vegetables stick to the inner tank 303, making it impossible to remove the dried vegetables. In addition, during the scraping process, the scraper can smear excess impurities on the surface of the dried vegetables, thereby improving its lubricity and reducing the evaporation rate of surface water.

[0052] Furthermore, a triangular axis 3042 is provided at the end of the first rotating shaft 3041 , and a triangular groove 30521 corresponding to the triangular axis 3042 is provided at the front end of the sleeve 3052 , and the triangular groove 30521 is a prism-shaped structure.

[0053] The front end opening of the triangular groove 30521 is relatively large, which facilitates the insertion of the triangular shaft 3042 into the triangular groove 30521 and its cooperation. As the diameter of the triangular groove 30521 becomes smaller, the sleeve 3052 is rotated until the triangular groove 30521 and the triangular shaft 3042 are aligned and cooperated.

[0054] Furthermore, the angle between the heat conducting plate 201 and the horizontal plane is 0-30°, the bottom of the inner tank 303 and the bottom of the double spiral scraper 304 are provided with a hollow groove 3043, a drain pipe 107 is provided in the casing 1, and the side of the drain pipe 107 is provided with a guide groove 106 that passes through it, and the guide groove 106 is located at the lower end of the inner tank 303.

[0055] When the double-helix scraper 304 scrapes off the condensed water and impurities on the inner wall of the inner tank 303, the condensed water and impurities flow out from the hollow groove 3043, flow into the guide groove 106, and overflow into the drain pipe 107 to be discharged outside the casing 1. The hollow groove 3043 improves the ventilation effect and prevents impurities from accumulating and soaking the dried vegetables, affecting the quality of the dried vegetables.

[0056] Furthermore, a first baffle 406 and a second baffle 407 are arranged between the rear chamber 102 and the lower air guide cover 403, a vent 4071 is provided on the first baffle 406, a slide groove 1011 is provided on the side of the partition box 101, a spring 1012 is provided in the slide groove 1011, the second baffle 407 is inserted into the slide groove 1011 and elastically slidably connected to the partition box 101, the lower end face of the second baffle 407 is fitted with the upper end face of the first baffle 406, a turntable 3062 is provided on the bottom side end face of the drive shaft 306, and a spiral spring 3063 fitted with the side of the turntable 3062 is provided on the side of the turntable 3062.

[0057] In the initial state, the second baffle 407 half blocks the vent 4071, and the air inlet flow is small. When the motor 301 drives the drive shaft 306 to rotate, the drive shaft 306 drives the turntable 3062 to rotate, and the spiral spring 3063 expands outward under the action of centrifugal force, squeezing the second baffle 407, causing the second baffle 407 to slide into the slide groove 1011, thereby increasing the opening of the vent 4071 and increasing the air intake flow. As the air flow increases, the speed of the electric double-helix scraper of the motor 301 also increases, preventing the dried vegetables from drying too quickly and causing the dried vegetables to stick to the inner wall of the inner tank 303.

[0058] Furthermore, a counterweight 3064 is provided at the end of the spiral spring 3063, and a pulley 3065 is rotatably connected to the counterweight 3064. The second baffle 407 is provided with an arc groove 4061 that is connected to the spiral spring 3063, and the arc groove 4061 is an elliptical structure.

[0059] The counterweight 3064 increases the centrifugal force at the end of the spiral spring 3063, and the pulley 3065 structure reduces the friction between the spiral spring 3063 and the second baffle 407, thereby improving the stability of the device. The arc groove 4061 structure makes the spiral spring 3063 and the second baffle 407 fit more closely, thereby reducing the noise generated by the counterweight 3064 suddenly hitting the second baffle 407.

[0060] Furthermore, an air inlet 5011 and an air outlet 5012 are provided on the left and right sides of the shell 501, a drain outlet 5013 is provided at the bottom of the shell 501, the reflective tube 502 is installed in the shell 501 and is rotatably connected thereto, a spiral blade 503 is provided on the outer end face of the reflective tube 502, and a filter screen 504 is installed on the inner side of the reflective cover, and the filter screen 504 is a barrel-shaped structure.

[0061] When the air flow enters the housing 501 from the air inlet 5011, the air flow blows on the spiral blade 503, causing the reflective cylinder 502 to rotate. The droplets are separated from the air flow under the action of centrifugal force. The air flow passes through the filter 504 and enters the dryer housing 501 again from the air outlet 5012 to dry the dried vegetables. The drain port 5013 is opened regularly to drain water.

[0062] When the dryer is in use, the dried vegetables (such as carrots) to be dried are neatly placed in the inner pot 303, with one dried vegetable placed in each inner pot 303, and the sealing door 105 at the front end of the casing 1 is ensured to be completely closed and locked to maintain good sealing. The first fan 404 and the second fan 405 are started first to ensure that the air flow can smoothly enter the front chamber 104 from the rear chamber 102 through the inner pot 303, and the heating mechanism 2 is turned on. The power switch of the heating mechanism 2 is turned on and preheated for a period of time until the heat conducting plate 201 reaches the set temperature, and the motor 301 is started to drive the drum 302 and the inner pot 303 to rotate through the drive shaft 306 and the gear transmission mechanism, so that the dried vegetables are evenly turned over in the inner pot 303. At this time, the spiral scraper 304 will also start to rotate to help remove condensed water and impurities on the inner wall of the inner pot 303. The impurities flow into the guide groove 106 and are discharged from the discharge pipe 107. According to the drying condition of the dried vegetables, The speed of motor 301 is adjusted. The motor 301 drives the spiral spring 3063 and the second baffle 407, which are linked together to adjust the opening of vent 4071 to control the drying speed and effect. The sealed door 105 is opened at regular intervals to check the dryness of the dried vegetables and ensure uniform drying. When the dried vegetables reach the desired dryness, the power switch of heating mechanism 2 is first turned off to stop heating. After waiting for a few minutes to allow the dried vegetables to gradually cool, the motor 301 is turned off, and the operation of the dried vegetable tumbling mechanism 3 is stopped. Finally, the first and second fans 404 and 405 are turned off to stop the wind circulation. The sealed door 105 is opened, and the dried dried vegetables are removed from the inner container 303. The inner container 303 and spiral scraper 304 are removed from the drum 302 and thoroughly cleaned with clean water and detergent to ensure no residue. The drain port 5013 of the gas-liquid separator 5 is opened to drain the waste liquid. The device can also be used for baking sausages, where the drain pipe can drain grease.

[0063] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
