Description

Technical Field

[0001] This invention relates to the field of fruit and vegetable drying technology, specifically to a fruit and vegetable hot air dryer and its usage method. Background Technology

[0002] my country has abundant agricultural resources and high yields of fruits and vegetables. However, aside from the sale of fresh vegetables, most of them spoil before reaching customers' tables. Currently, by drying fruits and vegetables, processing them into dried fruits and vegetables, the full utilization of these materials is achieved, expanding the application range of raw materials and making them an excellent source of nutritious processed products. Drying is typically done using a drying machine, which evaporates the moisture in the fruits and vegetables through hot air circulation. The drying machine has temperature and time control functions, which can be adjusted according to different types of fruits and vegetables to ensure the drying effect.

[0003] In order to ensure that each fruit and vegetable slice comes into contact with the hot air, the existing dryers require manual labor to spread the slices evenly on the dryer's trays, ensuring that there are enough gaps between them. This is tedious and involves a large number of fruit and vegetable slices, which makes the operation tiring for workers, increases the production cycle, and is inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to provide a hot air dryer for fruits and vegetables and its usage method, so as to solve the problem that the process of manually spreading fruit and vegetable slices evenly on the dryer tray is large in quantity and cumbersome, which leads to the fatigue of workers, increases the production cycle, and is inconvenient to use.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A hot air dryer for fruits and vegetables includes a drying rack. A detachable fruit and vegetable collection component is installed on the surface of the drying rack. The fruit and vegetable collection component has a large space with an upward opening and a bottom feeding port that can be opened and closed. A space dividing component is provided inside the fruit and vegetable collection component to divide the large space inside the fruit and vegetable collection component into multiple small spaces. A detachable storage basket is installed on the surface of the drying rack. The storage basket has an upward-opening placement groove, and the depth of the placement groove is the same as the thickness of the fruit and vegetable slices. The placement groove is divided into multiple small grooves, and each small groove can be aligned vertically with each small space.

[0007] Preferably, the fruit and vegetable collection assembly includes a collection box and a bottom sealing plate. The bottom sealing plate is slidably connected to the bottom surface of the collection box. The collection box is detachably installed on the surface of the drying rack. The bottom surface of the bottom sealing plate and the bottom surface of the collection box are on the same horizontal plane.

[0008] Preferably, the space separation component includes multiple fixed partitions and multiple movable partitions. The multiple fixed partitions are fixedly connected to the inner wall of the collection box at equal intervals, and the multiple movable partitions are slidably connected to the inner wall of the collection box at equal intervals.

[0009] Preferably, the rear end of the bottom sealing plate is configured as a second inclined surface, and the lower corner of the front end of each movable partition is configured as a first inclined surface.

[0010] Preferably, a vertically extendable spacing adjustment component is fixedly connected to the center of the bottom of the storage basket, and a first mesh cover is connected to the bottom of the storage basket through the spacing adjustment component.

[0011] Preferably, the spacing adjustment component includes a sleeve and a telescopic block. The sleeve is fixedly installed at the bottom of the storage basket, and the telescopic block is fixedly connected to the top of the first mesh cover. The sleeve and the telescopic block are slidably connected.

[0012] Preferably, a first return spring is fixedly connected between the sleeve and the telescopic block, an inclined limiting baffle is fixedly connected to the surface of the telescopic block, and a linkage plate is rotatably connected to the surface of the telescopic block.

[0013] Preferably, one end of the linkage plate is connected to a retractable handle, and both ends of the handle are fixedly connected to positioning rods. The surface of the storage basket is provided with positioning slots for the positioning rods to be inserted.

[0014] Preferably, a second slider is fixedly connected to both sides of the storage basket, and a plurality of first mounting slots for the second sliders to be embedded are provided on the surface of the drying rack. The inner wall of the drying rack is provided with a stacking guide slot for the second sliders to slide up and down, and the stacking guide slot is connected to all the first mounting slots.

[0015] The specific steps for using a hot air dryer for fruits and vegetables are as follows:

[0016] A. First, slice a large amount of fruits and vegetables, and then collect them in a collection box.

[0017] B. Next, insert the first inserts on both sides of the collection box into the second mounting slot and install the collection box onto the drying rack.

[0018] C. Next, the second sliders on both sides of the storage basket are inserted into the first mounting slot at the top of the surface of the drying rack. The storage basket is installed on the drying rack and is located at the bottom of the collection box. When installing the storage basket, when inserting the second sliders along the track of the first mounting slot, do not push them all the way down. Let the second sliders be slightly offset from the stacking guide slot.

[0019] D. Next, pull the bottom sliding plate outward to open the opening at the bottom of the collection box, and the fruit and vegetable slices inside the collection box will fall into the storage basket.

[0020] E. When the storage basket is full of fruit and vegetable slices, push back the bottom sliding plate to guide the excess fruit and vegetable slices back into the collection box;

[0021] F. Then push the storage basket so that the second slider goes to the bottom. Then the storage basket moves down along the track of the stacking guide groove through the second slider and falls to the bottom of the drying rack. Then repeat the operation from C to F to stack multiple storage baskets layer by layer.

[0022] G. When the storage basket on the drying rack is full, take out the collection box, then put the second mesh cover on top of the top storage basket, then close the door of the dryer and start the dryer to dry the fruit and vegetable slices with hot air.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. By setting up a bottom-sealing slide and a space-dividing component, the bottom-sealing slide can be pulled out to open the feeding port at the bottom of the collection box, allowing fruit and vegetable slices to fall into the storage basket. Due to the space-dividing component, the fruit and vegetable slices are separated into the small grooves above the storage basket before falling from the bottom of the collection box. This ensures that when the fruit and vegetable slices fall from the collection box into the storage basket, they will fall into the corresponding small grooves, achieving a uniform distribution of fruit and vegetable slices. Moreover, only the bottom-sealing slide needs to be pulled out, reducing the time spent on manual placement, which helps to reduce labor and shorten the production cycle.

[0025] 2. By setting up a collection box, which can be installed on the drying rack, fruit and vegetable slices can be placed in the storage basket in the dryer. This helps to prevent the fruit and vegetable slices from shifting during the handling process after they have been placed in the storage basket.

[0026] 3. By setting up a movable partition that can slide up and down, when the bottom sealing slide is pushed back, the fruit and vegetable slices between the storage basket and the fixed partition will be squeezed by the movable partition and the bottom sealing slide, so that the fruit and vegetable slices will be guided by the second inclined surface and moved back into the collection box. Then the discharge port of the collection box is closed, which is conducive to placing fruit and vegetable slices in the next storage basket. This allows for the continuous placement of fruit and vegetable slices in multiple storage baskets, which helps to reduce the drying cycle.

[0027] 4. By utilizing the elastic force of the first return spring to allow the sleeve and the telescopic block to slide against each other, a physical control method can be achieved. This helps to reduce the installation of electrical appliances, reduce energy output, and save energy. Moreover, the heat generated by the physical control is negligible, which helps to reduce the impact on hot air drying. Furthermore, through the design of the linkage plate in conjunction with the first return spring, the distance between the storage basket and the first mesh cover can be changed by simply inserting and removing the positioning rod. The operation is simple and convenient. Attached Figure Description

[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Please see Figures 1 to 18 The present invention provides a technical solution:

[0049] A hot air dryer for fruits and vegetables includes a dryer 1, which has a cavity and a closable door for opening and closing the cavity. The dryer 1 has a hot air blower on its side wall for drying the interior. It also includes a drying rack 2, which can be placed inside the cavity of the dryer 1. The drying rack 2 is used to accommodate multiple storage baskets 17 installed in layers to achieve uniform hot air drying. A detachable fruit and vegetable collection assembly is installed on the surface of the drying rack 2. The fruit and vegetable collection assembly has a large, upward-opening space, allowing materials to be fed into the collection box 6 from above. It also has a closable bottom feeding port. The vegetable collection assembly includes a collection box 6 and a bottom sealing slide plate 14. The bottom sealing slide plate 14 is slidably connected to the bottom surface of the collection box 6. By sliding the bottom sealing slide plate 14 back and forth, the feeding port at the bottom of the collection box 6 is opened, allowing the fruit and vegetable slices in the collection box 6 to fall from below. The collection box 6 is detachably installed on the surface of the drying rack 2. A detachable storage basket 17 is installed on the surface of the drying rack 2. The storage basket 17 is used to evenly separate the fruit and vegetable slices and allow them to receive hot air drying in the air inside the dryer 1 cavity. The storage basket 17 has an upward-facing placement slot, allowing the fruit and vegetable slices falling from below the collection box 6 to enter the placement slot of the storage basket 17 from above.

[0050] By placing the chopped fruit and vegetable slices in the collection box 6, and then installing the collection box 6 and the storage basket 17 onto the drying rack 2, the feeding port under the collection box 6 is opened by pulling the bottom sealing slide plate 14, allowing the fruit and vegetable slices to fall into the storage basket 17. Placing the fruit and vegetable slices into the storage basket 17 inside the dryer 1 helps prevent the fruit and vegetable slices from shifting during the handling process after being placed in the storage basket 17.

[0051] Furthermore, both sides of the collection box 6 are fixedly connected with first inserts 7, and the surface of the drying rack 2 is provided with a second mounting groove 5 for the first inserts 7 to be inserted. The collection box 6 can be installed and removed by moving it along the track of the second mounting groove 5. Both sides of the bottom sealing slide plate 14 are fixedly connected with second inserts 15, and the inner wall of the collection box 6 is provided with a first sliding groove 8 for the second inserts 15 to move back and forth. The bottom sealing slide plate 14 can be slid back and forth by moving it along the track of the first sliding groove 8. The storage basket 1 The second slider 18 is fixedly connected to both sides of the drying rack 2. The surface of the drying rack 2 is provided with a plurality of vertically arranged first mounting slots 3 at equal intervals for the second slider 18 to be inserted. The storage basket 17 can be installed and removed by moving it along the track of the first mounting slot 3. The inner wall of the drying rack 2 is provided with a stacking guide slot 4 for the second slider 18 to slide up and down. The stacking guide slot 4 is connected to all the first mounting slots 3. The storage basket 17 can be moved up and down by moving it along the track of the stacking guide slot 4.

[0052] Furthermore, the fruit and vegetable collection component is equipped with a space dividing component, which is used to divide the large internal space of the fruit and vegetable collection component into multiple small spaces. The depth of the placement slot of the storage basket 17 is the same as the thickness of the fruit and vegetable slices. In reality, the thickness of the fruit and vegetable slices is usually 5mm for the best drying effect and taste. The placement slot is divided into multiple small grooves, and each small groove can be aligned vertically with each small space. The placement slot can be divided into spaces with the same arrangement as the space dividing component by multiple warp and weft mesh plates, so that each small groove can be aligned vertically with each small space.

[0053] By setting the depth of the placement slot in the storage basket 17 to be the same as the thickness of the fruit and vegetable slices, only one row of fruit and vegetable slices can be placed in the placement slot of the storage basket 17 at most. Excess fruit and vegetable slices will be guided back into the collection box 6 when the bottom sealing slide 14 is pushed back, which helps to prevent the fruit and vegetable slices from piling up and causing uneven drying. By setting a space dividing component, the fruit and vegetable slices are separated in the collection box 6, and the position of the dividing point is aligned with the small groove. When the fruit and vegetable slices fall from the collection box 6 into the storage basket 17, they will fall into the corresponding small groove, so that each small groove can hold one fruit and vegetable slice, achieving the effect of uniform distribution of fruit and vegetable slices. Moreover, only the bottom sealing slide 14 needs to be pulled out, reducing the time for manual placement, which helps to reduce labor and shorten the production cycle.

[0054] Furthermore, the bottom surface of the sealing plate 14 is on the same horizontal plane as the bottom surface of the collection box 6. This is beneficial because when the storage basket 17 is located on the lower surface of the collection box 6, the storage basket 17 is also in contact with the bottom surface of the sealing plate 14. This helps to reduce the time when the fruit and vegetable slices fall and reduce the probability of them falling off course. Also, since the top surface of the storage basket 17 is in contact with the sealing plate 14, when the sealing plate 14 is pushed back, the fruit and vegetable slices between the storage basket 17 and the fixed partition 9 can be scooped up and guided back into the collection box 6.

[0055] Furthermore, the space separation component includes multiple fixed partitions 9 and multiple movable partitions 10. The multiple fixed partitions 9 are fixedly connected to the inner wall of the collection box 6 at equal intervals, and the multiple movable partitions 10 are slidably connected to the inner wall of the collection box 6 at equal intervals. A first slider 11 is fixedly connected to both sides of the movable partition 10. A second sliding groove 12 is provided on the surface of the fixed partition 9 to allow the first slider 11 to move up and down. The movable partition 10 can slide up and down by moving along the track of the second sliding groove 12. The fixed partitions 9 are arranged front and back, and the movable partitions 10 are arranged left and right, so that the setting direction of the movable partitions 10 is perpendicular to the moving direction of the bottom sealing slide plate 14. When the bottom sealing slide plate 14 moves past the movable partition 10, the movable partition 10 loses the support of the bottom sealing slide plate 14 and automatically slides down.

[0056] By setting up a movable partition 10 that can slide up and down, when the bottom sealing slide plate 14 is pushed back, the movable partition 10 will prevent the fruit and vegetable slices from moving backward. The fruit and vegetable slices between the storage basket 17 and the fixed partition 9 will be squeezed by the movable partition 10 and the bottom sealing slide plate 14, so that the fruit and vegetable slices will be guided by the second inclined surface 16 back into the collection box 6. Then the discharge port of the collection box 6 will be closed, which is conducive to placing fruit and vegetable slices in the next storage basket 17. This allows for the continuous placement of fruit and vegetable slices in multiple storage baskets 17, which helps to reduce the drying cycle.

[0057] Furthermore, the rear end of the bottom sealing plate 14 is set as a second inclined surface 16, and the front lower corner of each movable partition 10 is set as a first inclined surface 13. This is beneficial because during the back push of the bottom sealing plate 14, when the bottom sealing plate 14 moves to the second inclined surface 16 and contacts the first inclined surface 13, continuing to move the bottom sealing plate 14 will push the movable partition 10 back to its original position.

[0058] Furthermore, a vertically extendable spacing adjustment component is fixedly connected to the center of the bottom of the storage basket 17, and the bottom of the storage basket 17 is connected to a first mesh cover 32 through the spacing adjustment component.

[0059] By setting a spacing adjustment component, a certain gap can be made between the two storage baskets 17 to allow hot air to pass through, and to ensure that the gap between each storage basket 17 is equal, which is conducive to the uniform distribution of hot air. Since the gap between each storage basket 17 is equal, in conjunction with the spacing design between each first mounting groove 3, each second slider 18 can be placed in the track of the corresponding first mounting groove 3. The spacing adjustment component includes a sleeve 22 and a telescopic block 23. The sleeve 22 is fixedly installed at the bottom end of the storage basket 17, and the telescopic block 23 is fixedly connected to the top end of the first mesh cover 32. The sleeve 22 and the telescopic block 23 are slidably connected. The distance between the storage basket 17 and the first mesh cover 32 is changed by sliding the sleeve 22 and the telescopic block 23 against each other.

[0060] Furthermore, a first return spring 24 is fixedly connected between the sleeve 22 and the telescopic block 23, an inclined limit baffle 25 is fixedly connected to the surface of the telescopic block 23, a linkage plate 26 is rotatably connected to the surface of the telescopic block 23, a telescopic handle 30 is connected to one end of the linkage plate 26, a positioning rod 31 is fixedly connected to both ends of the handle 30, and a positioning slot 21 for the positioning rod 31 to be inserted is provided on the surface of the storage basket 17.

[0061] By utilizing the elastic force of the first return spring 24 to allow the sleeve 22 and the telescopic block 23 to slide against each other, physical control can be achieved. This reduces the need for electrical components, decreases energy output, and saves energy. Furthermore, the heat generated by physical control is negligible, minimizing its impact on hot air drying. Additionally, by designing the linkage plate 26, when it rotates to the point where it is blocked by the limiting baffle 25, and one end of the positioning rod 31 is inserted into the positioning slot 21, that is, when the angle, length, and one end position of the linkage plate 26 are determined, the other end of the linkage plate 26 will stretch the first return spring 24. The positioning spring 24 stores elastic potential energy, causing the telescopic block 23 to move to a designated position, thus ensuring that the distance between the storage basket 17 and the first mesh cover 32 is fixed. When the positioning rod 31 is pulled out of the positioning slot 21, the restriction on the position of the linkage plate 26 is released. Under the elastic force of the first return spring 24, the telescopic block 23 will retract into the sleeve 22, thereby reducing the distance between the storage basket 17 and the first mesh cover 32. In other words, the distance between the storage basket 17 and the first mesh cover 32 can be changed by simply inserting and removing the positioning rod 31. The operation is simple and convenient.

[0062] Furthermore, a third sliding groove 27 is provided at one end of the linkage plate 26, and a second return spring 28 is fixedly installed in the third sliding groove 27. A third insert 29 is fixedly connected to one end of the second return spring 28. The handle 30 is fixedly connected to the third insert 29. By setting the second return spring 28, when the handle 30 is pulled and then released, the handle 30 automatically returns to its original position under the action of the second return spring 28, eliminating the need to insert the handle 30 back into place. This simplifies the operation and improves the drying effect.

[0063] Furthermore, a fruit and vegetable hot air dryer also includes a second mesh cover 34. By providing the second mesh cover 34, after the collection box 6 is removed, it can cover the top surface of the uppermost storage basket 17, preventing fruit and vegetable pieces from falling during drying. The bottom ends of both the first mesh cover 32 and the second mesh cover 34 are fixedly connected with mating strips 33. The top of the storage basket 17 is provided with a mating groove 19 for the mating strips 33 to be inserted. By inserting the mating strips 33 into the mating grooves 19, the connection between the upper and lower storage baskets 17 is stable, which helps prevent the storage baskets 17 from falling. The drying process generates shaking. Multiple equally spaced buffer springs 20 are fixedly connected inside the docking groove 19. These springs help to cushion the movement when the storage basket 17 falls and the docking strip 33 is embedded in the docking groove 19. The storage basket 17, the first mesh cover 32, the second mesh cover 34, the warp mesh plate, and the weft mesh plate are all mesh structures, which facilitates the flow of hot air on the surface of the fruit and vegetable slices. The mesh aperture is smaller than the size of the fruit and vegetable slices, preventing them from falling out of the storage basket 17. The mesh lines are omitted in the attached diagram for clarity of the structure.

[0064] The specific operating method of this fruit and vegetable hot air dryer is as follows: Place the drying rack 2 inside the dryer 1. First, slice a large quantity of fruits and vegetables, then place them uniformly in the collection box 6. The fixed partitions 9 and movable partitions 10 inside the collection box 6 initially divide the fruit and vegetable slices into various areas, and the areas separated in the storage basket 17 correspond one-to-one with the areas separated by the fixed partitions 9 and movable partitions 10. Then, move the collection box 6 onto the drying rack 2 and install it, positioning it at the bottom of the collection box 6. Next, pull out the bottom sealing slide 14 to open the opening at the bottom of the collection box 6, allowing the fruits and vegetables inside to pass through. The fruit and vegetable slices fall into the storage basket 17. Since the areas divided within the storage basket 17 correspond one-to-one with the areas divided by the fixed partition 9 and the movable partition 10, as the bottom-sealing slide plate 14 is pulled out, the areas divided by the fixed partition 9 and the movable partition 10 gradually open and connect with the areas divided by the storage basket 17, allowing the fruit and vegetable slices to fall into the corresponding areas within the storage basket 17. Since the depth of the groove in the storage basket 17 is equal to the thickness of the fruit and vegetable slices, each area divided by the storage basket 17 contains one fruit and vegetable slice, achieving a uniform distribution effect. Moreover, only the bottom-sealing slide plate 14 needs to be pulled or pushed, reducing labor and speeding up the production cycle.

[0065] As the bottom-sealing slide plate 14 is pulled outward, each time it passes a movable partition 10, the movable partition 10 will descend due to the lack of support, causing the first slider 11 to move downward along the track of the second sliding groove 12 until it falls onto the warp plate corresponding to the storage basket 17. When the bottom-sealing slide plate 14 is pushed back, the movable partition 10 will restrict the movement path of the fruit and vegetable slices. The fruit and vegetable slices between the storage basket 17 and the fixed partition 9 will be squeezed by the movable partition 10 and the bottom-sealing slide plate 14, so that the fruit and vegetable slices will be guided by the second inclined surface 16 back into the collection box 6. When the second inclined surface 16 moves to contact the first inclined surface 13, it will continue to move and push the movable partition 10 back to its original position.

[0066] By inserting the first inserts 7 on both sides of the collection box 6 into the second mounting slots 5, the collection box 6 is installed onto the drying rack 2. By inserting the second sliders 18 on both sides of the storage basket 17 into the uppermost first mounting slot 3 on the surface of the drying rack 2, the storage basket 17 is installed onto the drying rack 2 and positioned below the collection box 6. When installing the storage basket 17, the second sliders 18 are inserted along the track of the first mounting slot 3 without being pushed all the way in initially. The second sliders 18 are slightly offset from the stacking guide slot 4 to prevent the second sliders 18 from being pulled... The movable storage basket 17 descends along the track of the stacking guide groove 4. When the storage basket 17 is full of fruit and vegetable slices, the storage basket 17 is pushed so that the second slider 18 reaches the bottom. Then the storage basket 17 moves down along the track of the stacking guide groove 4 through the second slider 18. Then the operation is repeated to stack multiple storage baskets 17 layer by layer. When the storage baskets 17 on the drying rack 2 are full, the collection box 6 is taken out, and the second mesh cover 34 is placed on the top of the top storage basket 17. Then the door of the dryer 1 is closed, and the dryer 1 is started to dry the fruit and vegetable slices with hot air.

[0067] During the stacking of multiple storage baskets 17, when the upper storage basket 17 falls to the lower storage basket 17, the connecting strip 33 on the upper storage basket 17 first inserts into the connecting groove 19 on the lower storage basket 17 for stacking. Since the distance between each storage basket 17 is fixed, the second sliders 18 on both sides of each layer of storage basket 17 are aligned with the first mounting groove 3 relative to the height, and the storage basket 17 can be pulled outward to move the entire storage basket 17 out of the dryer 1 at the same time, which is convenient to use.

[0068] When it is necessary to remove the middle layer of the storage basket 17 in the dryer 1, for example, if a bad fruit or vegetable slice is found in a middle layer, first pull out the pull handle 30 of that layer and the pull handle 30 at the top of that layer, so that the positioning rod 31 is pulled out from the positioning slot 21. At this time, release the pull handle 30, and the first return spring 24 on the two layers of storage basket 17 will be unrestricted and will automatically return to its original position under the elastic force, so that the telescopic block 23 will be pulled to retract into the sleeve 22, so that the docking strip 33 is moved out from the docking groove 19, and the storage basket 17 of that layer can be removed at this time.

[0069] When performing the pull handle 30 and linkage plate 26 reset operation, first rotate the linkage plate 26 until it is blocked by the limit baffle 25, and then insert the positioning rod 31 into the positioning slot 21. Since the angle of the linkage plate 26 is restricted and the length of the linkage plate 26 is also determined, the end of the positioning rod 31 is also positioned, so that the position of one end of the telescopic block 23 is determined, that is, the telescopic block 23 will be stretched out to its original state, so that the distance between all the storage baskets 17 is consistent.

[0070] To prevent misalignment between the middle layer storage basket 17 and the corresponding height first mounting slot 3 when disconnecting the middle layer storage basket 17 from the upper and lower end storage baskets 17, the storage basket 17 can be dragged along, allowing for one-handed operation without affecting the process.

[0071] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
