Description

Technical Field

[0001] The invention relates to the field of fruit dryers, in particular to an automatic intelligent dryer for navel oranges. Background Art

[0002] The dried navel orange products include dried navel orange peels and dried navel orange slices. Both drying methods for the dried navel oranges are to directly arrange the dried objects on mesh disks, and then place multiple mesh disks in a vertically stacked state into a hot air dryer, and simultaneously perform timed drying on each dried object. This method can simultaneously process batches of dried objects, but because the drying airflow is usually sprayed upward from a nozzle installed on the bottom of the drying bin, the dried objects on the upper layer will be blocked by the dried objects on the lower layer. Therefore, the drying speeds of the dried objects on different layers vary greatly, resulting in inconsistent drying effects on the dried objects on different layers. The hot air dryer cannot identify the drying status of each dried object individually, and can only simultaneously perform uniform drying on all dried objects in a timed drying manner. Therefore, the overall drying time required for the dried navel oranges is relatively long, affecting the overall production efficiency of the dried navel oranges. Summary of the invention

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Embodiment 1

At the same time, the circulating airflow mechanism sucks the hot air flow in the inner cabin 2 through each exhaust pipe 3 to form a circulating hot air flow in the inner cabin 2; all exhaust pipes 3 and all jet pipes 4 are connected to the circulating airflow mechanism; each second fixed plate 22 is slidably connected with a plurality of groups of support rods 5; each group of support rods 5 is composed of four support rods 5, and each group of support rods 5 is surrounded by four support rods 5 on the outside of a corresponding jet pipe 4; the lower ends of all support rods 5 on the same second fixed plate 22 are fixedly connected to a connecting plate 51; each second fixed plate 22 is fixedly connected to two electric lifting push rods 52; the telescopic ends of the two electric lifting push rods 52 on the same second fixed plate 22 are fixedly connected to the corresponding connecting plate 51.

[0024] like Figure 3 and Figure 4As shown, the circulating airflow mechanism includes an exhaust main pipeline 31, an exhaust branch pipeline 32, an air jet main pipeline 41, an air jet branch pipeline 42 and a circulating hot air blower; the drying machine body 1 is equipped with a circulating hot air blower; each first fixed plate 21 is fixedly connected with an exhaust main pipeline 31; each first fixed plate 21 is fixedly connected with a plurality of exhaust branch pipelines 32 connected to the corresponding exhaust main pipeline 31; each exhaust pipe 3 is respectively connected to the corresponding exhaust branch pipeline 32; all the exhaust main pipelines 31 are connected to the air inlet end of the circulating hot air blower; each second fixed plate 22 is fixedly connected with an air jet main pipeline 41; each A plurality of jet branch pipes 42 connected to the corresponding jet main pipe 41 are fixedly connected in each second fixed plate 22; the jet branch pipes 42 are pluggablely connected to the jet main pipe 41. When the staff pulls the second fixed plate 22 outward, the second fixed plate 22 can drive the jet branch pipes 42 to be pulled out from the jet main pipe. When the staff pushes the second fixed plate 22 back inward, the second fixed plate 22 can drive the jet branch pipes 42 to be inserted back into the jet main pipe; each jet pipe 4 is respectively connected to the corresponding jet branch pipe 42; all the jet branch pipes 42 are commonly connected to the air outlet of the circulating hot air blower.

[0025] like Figure 6 As shown, each exhaust pipe 3 is provided with a drying cylinder 34, which is composed of a cylinder body and a desiccant filled inside the cylinder body, and a vent structure for air flow to flow up and down is provided at both ends of the cylinder body; each exhaust pipe 3 is composed of an upper fixed tube body and a lower movable tube body, and the drying cylinder 34 is placed in the lower movable tube body, and the upper fixed tube body and the lower movable tube body are fixed to each other by a threaded structure, which is convenient for the staff to remove the lower movable tube body from the upper fixed tube body, and regularly replace the drying cylinder 34 in the lower movable tube body, so as to improve the absorption efficiency of the desiccant in the drying cylinder 34 for moisture in the air flow. First, the navel orange dried material placement work of the automatic navel orange intelligent drying machine of the present invention is carried out.

[0026] After the staff opens the hatch 11, they pull out the second fixed plates 22 of each layer in turn, driving the jet branch pipes 42, jet pipes 4 and support rods 5 connected thereto to move outward, and place the dried objects in the same batch above the support rod 5 groups corresponding to each jet pipe 4, and the dried objects are supported above the jet pipe 4 by the support rods 5 in the support rod 5 groups. The staff then pushes the second fixed plates 22 and the jet branch pipes 42, jet pipes 4 and support rods 5 connected thereto back into the inner cabin 2, so that the dried objects on each support rod 5 group are aligned between the corresponding jet pipe 4 and the exhaust pipe 3. The staff then controls each electric lifting push rod 52 to pull the connected connecting plate 51 upward, and the connecting plate 51 pushes the support rod 5 to prop up the dried objects, so that the dried objects are close to the exhaust pipe 3 upward but not in contact with it. Then the staff closes the hatch 11 and turns on the drying machine body 1 to carry out drying. At this time, the lighting system in the drying machine body 1 provides lighting to the inside of the inner cabin 2, and the photosensors 33 in each exhaust pipe 3 can all recognize the light provided by the lighting.

[0027] Then, the drying process of the dried navel oranges of the automatic navel orange intelligent drying machine of the present invention is carried out.

[0028] The circulating hot air blower in the drying machine body 1 transports the hot air flow along the jet main pipe 41 and the jet branch pipe 42, and at the same time sprays the hot air flow upward through each jet pipe 4. At the same time, the circulating hot air blower exhausts each exhaust pipe 3 along the exhaust main pipe 31 and the exhaust branch pipe 32. After the hot air flow is sprayed upward into the inner cabin 2, the exhaust pipe 3 promptly draws away the hot air flow in the inner cabin 2, so that the circulating hot air blower circulates and transports the hot air flow in the inner cabin 2 through each jet pipe 4 and the corresponding exhaust pipe 3. At this time, the hot air flow forms a plurality of hot air flow flow areas between each jet pipe 4 and the corresponding exhaust pipe 3, and the dried objects on each support rod 5 group are dried by the hot air flow in the corresponding hot air flow flow area, so that each dried object is dried independently. During this period, the desiccant in the drying cylinder 34 dries the hot air flow passing through the exhaust pipe 3 in time, and the moisture absorbed by the hot air flow in the process of drying the dried objects is transferred to the desiccant, so that the hot air flow can maintain a dry state and efficiently dry the dried objects.

[0029] As the hot air flows in each hot air flow zone continuously and individually dry the corresponding drying objects, the moisture content of the drying objects will be significantly reduced, and the overall weight of the drying objects will be significantly reduced. When a certain drying object completes the drying process first, under the combined action of the suction force of the exhaust pipe 3 and the blowing force of the jet pipe 4, the gravity of the drying object has been reduced to a level sufficient to be blown upward to the bottom of the corresponding exhaust pipe 3 by the blowing force, and the drying object will remain firmly adsorbed on the bottom of the exhaust pipe 3. At this time, the photosensor 33 in the exhaust pipe 3 is blocked by the light from the drying object, and a completion signal is fed back to the drying machine body 1 through the circuit system, and the drying machine body 1 can recognize that the drying object has been completed. During the drying process, since the exhaust pipe 3 is blocked by the adsorbed drying objects, the suction amount of the hot air flow from the jet pipe 4 below it will be greatly reduced, and the hot air flow blown up by the jet pipe 4 below will also be blocked by the drying objects. Therefore, the hot air flow blown upward from the jet pipe 4 will flow to the adjacent exhaust pipe 3 and be sucked away. The hot air flow will be added to the drying process of the adjacent drying objects, thereby accelerating the drying speed of the adjacent drying objects, allowing the adjacent drying objects to complete the drying process faster and be adsorbed upward on the exhaust pipe 3 by the blowing force of the hot air flow. A chain reaction occurs based on this principle, which can not only improve the overall drying efficiency of all the drying objects in the inner cabin 2, but also enhance the consistency of the overall drying effect of all the drying objects.

[0030] During this process, each time the drying process of an object to be dried is completed, the object to be dried will be affected by the blowing force of the hot air flow from the corresponding hot air flow area and will be blown upward to be close to the bottom of the corresponding exhaust pipe 3. When the light-sensitive sensor 33 feeds back a signal to the drying machine body 1, the drying machine body 1 will record the total number of objects to be dried that have completed the drying process. Due to the differences in the volumes of different objects to be dried, the weights of different objects to be dried will also vary. Even after the drying process is completed, objects with heavier weight will not be blown upward to be close to the bottom of the corresponding exhaust pipe 3 by the blowing force of the hot air flow. Therefore, when the drying machine body 1 recognizes that 80% of the objects to be dried have completed the drying process, it means that all the objects to be dried in the inner cabin 2 have completed the drying process, and the staff can be promptly informed that the drying process of this batch of objects has been completed. There is no need to use a long-term timed drying method to dry the objects to be dried, which greatly shortens the overall drying process time of all the objects to be dried in the inner cabin 2.

[0031] In addition, when the drying machine body 1 fails to identify that 80% of the dried objects have completed the drying process after exceeding the specified time, it means that there are a large number of heavy dried objects in the batch of dried objects, resulting in the inability of the hot air flow blowing force to blow the dried objects that have completed the drying process upwards. At this time, it is necessary to electrically lift and pull the connecting plate 51 to drive the support rod 5 groups to move upwards, and the support rod 5 groups push the corresponding dried objects upwards and close to the bottom of the exhaust pipe 3. At this time, the dried objects that have completed the drying process will be tightly adsorbed on the bottom of the exhaust pipe 3 under the action of the hot air flow blowing force. Then the electric lifting pushes the connecting plate 51 to drive the support rod 5 groups downward away from the exhaust pipe 3, and the dried objects that have completed the drying process and are tightly adsorbed on the bottom of the exhaust pipe 3 will be separated from the support rod 5 groups, allowing the drying machine body 1 to accurately identify that 80% of the dried objects have completed the drying process.

[0032] The reason why the present invention uses the photosensitive sensor 33 to monitor the adsorption state of the dried object instead of using the pressure sensor to monitor the weight of the dried object is that the pressure sensor can only be installed in the contact area between the support rod 5 group and the dried object. The dried object will secrete a large amount of juice such as sugar during the drying process. Once the juice adheres to the pressure sensor, it will seriously affect the accuracy of the pressure sensor in measuring the weight of the dried object. In addition, the hot air flow ejected upward from the air jet pipe 4 will also generate an upward thrust on the dried object. This unstable thrust will also interfere with the weight measurement of the dried object. The use of the photosensitive sensor 33 to monitor the adsorption state of the dried object does not require precise measurement, is subject to fewer interference factors, and is conducive to improving the accuracy of monitoring the adsorption state of the dried object.

[0033] like Figure 4 As shown, when the dried object is navel orange slices, each support rod 5 is fixedly connected with a fine needle 6. Since the fine needles 6 are configured as a pointed cone structure that contracts upward, under the combined action of the suction force of the exhaust pipe 3 and the blowing force of the air jet pipe 4, the dried navel orange peels can smoothly detach from the pointed cone structure of the fine needles 6 and move upward.

[0034] Since the navel orange slices are thin and slippery, after the navel orange slices are placed on the support rods 5, when the wind speed of the hot air flow blown out from the air jet pipe 4 is relatively high, the navel orange slices are easily blown to the surroundings by the wind force and fall off the support rods 5. Therefore, the staff needs to pre-pierce the navel orange slices into the fine needles 6 of each support rod 5, and limit the left and right deviation of the navel orange slices by the fine needles 6, so that the navel orange slices can be smoothly adsorbed upwards in the corresponding exhaust pipe 3 after the drying process is completed. Embodiment 2

[0035] On the basis of Example 1, Figure 1-Figure 6As shown, the upper ends of all the support rods 5 on the same second fixing plate 22 of this embodiment are commonly fixedly connected with a supporting net 7 .

[0036] Even if the navel orange slices fall off the fine needles 6, or the navel orange slices still fall after being adsorbed upwards, the navel orange slices will fall on the supporting net 7. Since the supporting net 7 is always located between the exhaust pipe 3 and the air jet pipe 4, the navel orange slices can be fully dried by the hot air flow flowing between the exhaust pipe 3 and the air jet pipe 4, so that the navel orange slices that fall on the supporting net 7 can also complete the corresponding drying process smoothly. Embodiment 3

[0037] On the basis of Example 2, each exhaust pipe 3 of this embodiment is connected to a sealing plate 36 through a connecting piece 35, and the sealing plate 36 is flush with the bottom of the exhaust pipe 3; the connecting piece 35 uses a spring telescopic rod component, which is composed of a telescopic rod and a spring sleeved on the outer surface of the telescopic rod.

[0038] When the dried object is navel orange peel, the navel orange peel needs to be placed on the support rod 5 group with the middle part arched upward. Under the combined effect of the suction force of the exhaust pipe 3 and the blowing force of the air jet pipe 4, the navel orange peel that has completed the drying process is adsorbed upward to the bottom of the exhaust pipe 3. At this time, the arched part of the middle part of the navel orange peel will push the sealing plate 36 to drive the connecting piece 35 composed of the spring telescopic rod component to compress upward, so that the arched part of the middle part of the navel orange peel can smoothly recess upward into the exhaust pipe 3, avoiding the interference of the sealing plate 36 with the arched part of the middle part of the navel orange peel. After the middle part of the navel orange peel enters the exhaust pipe 3, the blocking effect of the navel orange peel on the exhaust pipe 3 can be improved, avoiding the large air leakage analysis structure between the navel orange peel and the exhaust pipe 3, which affects the adsorption effect of the navel orange peel in the exhaust pipe 3, and achieving the navel orange peel being firmly adsorbed in the exhaust pipe 3.

[0039] When the dried object is navel orange slices, and when the rib structure in the middle of the navel orange slices has been removed in advance, there will be a hollow hole structure in the middle of the navel orange slices. Under the combined action of the suction force of the exhaust pipe 3 and the blowing force of the air jet pipe 4, the dried navel orange slices are adsorbed upward to the bottom of the exhaust pipe 3. After the drying process is completed, the hollow hole structure in the middle of the navel orange slices is likely to shrink to the surroundings to form a larger hollow hole structure. When the dried navel orange slices are adsorbed upward to the bottom of the exhaust pipe 3, the hollow holes formed in the middle area of ​​the navel orange slices will be in close contact with the sealing plate 36 in the exhaust pipe 3 in time. Therefore, the sealing plate 36 can reduce the size of the leakage hole structure formed by the hollow hole structure in the middle area of ​​the navel orange slices, reduce the damage caused by the leakage holes in the middle of the navel orange slices to the adsorption effect of the navel orange slices, and achieve the navel orange slices can be adsorbed to the bottom of the exhaust pipe 3 under sufficient suction force.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application.
