Description

Technical Field

[0001] The present application relates to the technical field of fruit and vegetable drying equipment, and in particular to a low-fat fruit and vegetable crisp processing device and a process thereof. Background Art

[0002] Fruit and vegetable chips are a healthy food that can satisfy your snack cravings and provide nutritional supplements. They are usually made from fruits and vegetables that have been dried or baked without adding too much oil, so their fat content is relatively low. This low-fat fruit and vegetable chip retains the fiber content of the original fruits and vegetables, and contains a large amount of vitamins, minerals and antioxidants, which can supplement the body's daily nutritional needs.

[0003] The production and processing of fruit and vegetable chips generally include washing, slicing, drying, packaging and other processes. Some fruit and vegetable chips will be crushed into powder after drying so that they can be made into packaged beverage powder, which is more convenient for drinking. In the drying process, hot air drying or freeze drying is usually used. The hot air drying method can retain the natural taste and aroma of the ingredients, allowing the fruit and vegetable chips to present the unique flavor of the raw materials while maintaining a crispy taste. In addition, hot air drying consumes less energy and is more conducive to energy saving.

[0004] When fruit and vegetable slices are drying, especially some high-sugar fruit slices, as the water on the surface of the fruit slices evaporates, the sugar in the fruit will gradually concentrate and form a sticky layer on the surface of the fruit slices, which will cause the fruit slices to stick together and also cause the fruit slices to stick to the trays they are placed on, which will increase the difficulty of operation in subsequent processing.

At the same time, the fan blades drive the air inlet baffle to slide back and forth in the sealing box through the first driving assembly and the second driving assembly. The air inlet baffle can block the hot air flow from entering the air inlet at intervals during the reciprocating sliding process, so that the hot air flow in the air duct is blown out at intervals, and the hot air flow blown out at intervals blows the fruit and vegetable slices away from the supporting side wall at intervals, thereby effectively preventing the fruit and vegetable slices from adhering to the placement board during the drying process; 3. When the placement slot has two inclined supporting side walls, the fruit and vegetable slices are placed on one of the inclined supporting side walls, which also makes the fruit and vegetable slices inclined. At this time, two groups of air ducts are provided, and two groups of first drive components, second drive components and fan blades are also provided. The two groups of air ducts are respectively provided with two air inlets, and each group of air ducts shares one of the air inlets. Each group of fan blades blocks the corresponding air inlets through an air inlet baffle of the first drive component and the second drive component respectively, and the two air inlets are not connected or blocked at the same time, so that the two groups of air ducts can blow out hot air flows at different times during operation, that is, the air outlets corresponding to the two groups of air ducts blow out hot air flows alternately, so that the fruit and vegetable slices can swing back and forth between the two supporting side walls of the same placement slot.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-6 This application is described in further detail. Example 1

[0020] Embodiment 1 of the present application discloses a low-fat fruit and vegetable crisp chip processing device and its process, wherein the low-fat fruit and vegetable crisp chip processing device comprises a cleaning unit, a slicing unit and a drying unit in sequence, wherein the cleaning unit may comprise an ultrasonic cleaning machine or a bubble cleaning machine commonly available on the market, which is used to clean fresh fruits and vegetables picked, and completely remove agricultural pesticides remaining on the surface of fruits and vegetables. A conveyor belt may be set up between the cleaning unit and the slicing unit, and the washed fruits and vegetables are sent into the slicing unit by means of the conveyor belt. The slicing unit may comprise a common fruit and vegetable slicer commonly available on the market, which is used to slice the washed fruits and vegetables, and the thickness of the slices may be determined according to the type of fruits and vegetables. After slicing, the fruit and vegetable slices are sent into the drying unit for drying.

[0021] Reference Figure 1 and Figure 2 The drying unit includes a box body 1 and a hot air blower (not shown). A door that can be opened and closed is provided on one side of the box body 1 to facilitate the taking and delivery of fruit and vegetable slices. The hot air blower is fixed on the back of the box body 1 to provide hot air for drying inside the box body 1. There are multiple horizontally placed storage boards 2 in the box body 1, and the multiple storage boards 2 are spaced up and down.

[0022] In the embodiment of the present application, all the storage boards 2 are hollow mesh structures, so that airflow can pass through the storage boards 2, and the number of storage boards 2 is set to three layers. In other embodiments of the present application, multiple through holes can be opened on the storage boards 2 to replace the hollow mesh structure, so that the storage boards 2 can also allow airflow to pass through. At the same time, the number of storage boards 2 can be increased or decreased according to the actual volume size of the box 1.

[0023] A bracket 3 is provided under each layer of the storage board 2. The bracket 3 is also placed horizontally and fixed on the inner wall of the box body 1. The storage board 2 is horizontally slidable along the depth direction of the box body 1 and connected to the top of the bracket 3. The bracket 3 can be used as a supporting object for the storage board 2, so that the storage board 2 can be pulled out or pushed back into the box body 1 along the bracket 3.

[0024] A fan blade 4 is provided on both sides of each layer of the storage board 2. The fan blade 4 is rotatably connected to the side wall of the bracket 3 through a rotating shaft. The rotation axis of the fan blade 4 is horizontal and extends along the width direction of the box body 1. The length of the fan blade 4 exceeds the upper surface of the storage board 2, so that the fan blade 4 can accelerate the hot air to blow to the surface of the storage board 2 when rotating. The hot air blower conveys the hot air to the inside of the box body 1 through the connecting pipe 11. A part of the connecting pipe 11 is provided with a driving air outlet 12. The driving air outlet 12 corresponds to the fan blade 4 one by one and faces the direction of the fan blade 4. The hot air blows from the driving air outlet 12 to the surface of the fan blade 4 to drive the fan blade 4 to rotate by itself. The faster the wind speed output by the hot air blower, the faster the fan blade 4 rotates.

[0025] A plurality of placement grooves 21 are provided on the placement plate 2, and the plurality of placement grooves 21 are spaced apart along the width direction of the box body 1, and each placement groove 21 extends along the depth direction of the box body 1. The specific number of the placement grooves 21 can be increased or decreased according to the actual width of the placement plate 2, and each placement groove 21 includes an inclined supporting side wall 22 and a vertical wall surface, and the supporting side wall 22 is used to place and support fruit and vegetable slices, so that the fruit and vegetable slices can remain in an inclined state after being placed on the supporting side wall 22.

[0026] The fan blades 4 are driven by the hot air blower through the driving air port 12 on the connecting pipe 11. When the hot air blower delivers hot air flow into the box body 1, a part of the hot air flow is blown out from the driving air port 12 and blows to the surface of the fan blades 4, thereby driving the fan blades 4 to rotate. The rotating fan blades 4 can concentrate the hot air flow to the direction of the placement plate 2, and the placement plate 2 is laid with fruit and vegetable slices to be dried. Therefore, the rotating fan blades 4 can concentrate the hot air to the surface of the fruit and vegetable slices to be dried, thereby accelerating the drying. At the same time, the fruit and vegetable slices are placed on the inclined supporting side wall 22, so the fruit and vegetable slices are also inclined. The inclined placement of the fruit and vegetable slices allows more fruit and vegetable slices to be placed on the placement plate 2 at the same time, improving the utilization rate of the space, and the inclined placement of the fruit and vegetable slices can make their surfaces have better contact with the hot air flow, thereby improving the drying efficiency and drying effect.

[0027] Reference Figures 3 to 5A group of horizontal air ducts 5 is arranged below the storage board 2. The group of air ducts 5 includes a plurality of air ducts arranged side by side. The plurality of air ducts 5 arranged side by side are spaced apart along the depth direction of the box body 1. The specific number of air ducts 5 can be increased or decreased according to the actual length of the storage board 2, so that the group of air ducts 5 can cover the lower surface of the storage board 2 as much as possible. Each air duct 5 extends along the width direction of the box body 1, and each air duct 5 is provided with an air outlet 51 corresponding to the number of the placement slots 21. Each air outlet 51 on the same air duct 5 is inclined toward the supporting side wall 22 on one side of the corresponding placement slot 21.

[0028] This group of air ducts 5 penetrates from the right side wall of the bracket 3, and the right side pipes of this group of air ducts 5 are connected together, and a common air inlet 52 is provided. The air inlet 52 is located on the right side of the air ducts 5, and the hot air blower transports hot air flow to the group of air ducts 5 through the same air inlet 52. The hot air blower is connected to the air inlet 52 through a connecting pipe 11.

[0029] A sealing box 6 is fixed on one side wall of the bracket 3. The air inlet 52 of the air duct 5 is located in the sealing box 6. An air inlet baffle 61 is slidably connected to the position corresponding to the air inlet 52 in the sealing box 6. The air inlet 52 is located on the moving path of the air inlet baffle. The air inlet baffle 61 can intermittently open or block the air inlet 52 during the reciprocating sliding process. A cam 62, a driving rod 63 and a return member 64 are also provided in the sealing box 6. The return member 64 can be a tension spring. The cam 62 is rotatably connected to the sealing box 6, and the rotation axis is parallel to the length direction of the air duct 5. A sealed cavity 65 is also provided in the sealing box 6. The air inlet baffle 61 slides in the sealed cavity 65. The driving rod 63 extends along the depth direction of the box body 1 and is slidably connected to the sealing box 6. One end of the driving rod 63 is in sliding contact with the edge of the cam 62, and the other end of the driving rod 63 extends into the sealed cavity 65 and is fixedly connected to the air inlet baffle 61. The return member 64 is located in the sealed cavity 65, one end of the return member 64 is fixed to the end of the driving rod 63, and the other end is fixed to the inner wall of the sealed cavity 65. The return member 64 can keep one end of the driving rod 63 always in contact with the outer edge of the cam 62. When the cam 62 rotates, it will push the driving rod 63 to slide back and forth. During the reciprocating sliding of the driving rod 63, the air inlet baffle 61 will be driven to reciprocate synchronously. The reciprocating air inlet baffle 61 will block the air inlet 52 at intervals.

[0030] Furthermore, the seal box 6 is rotatably connected with a driving gear 66 and a driven gear 67, the driving gear 66 meshes with the driven gear 67, and the diameter of the driving gear 66 is smaller than the diameter of the driven gear 67, so that the driving gear 66 rotates faster than the driven gear 67. The driven gear 67 is coaxially fixed with the cam 62, and the fan blade 4 is coaxially fixed with the driving gear 66. After the fan blade 4 rotates, the meshed driving gear 66 and the driven gear 67 drive the cam 62 to rotate, thereby driving the air inlet baffle 61 to block the connecting pipe 11 from delivering hot air to the air inlet 52, and finally realizing the interval blowing of the air guide 5.

[0031] The hot air blower simultaneously delivers hot air to all the air ducts 5 through an air inlet 52, so that the hot air flow blown out from the air outlet 51 can spray toward the fruit and vegetable slices from bottom to top, and the fan blades 4 drive the cam 62 to rotate through the meshing driving gear 66 and the driven gear 67, thereby driving the air inlet baffle 61 to slide back and forth. During the reciprocating sliding process, the air inlet baffle 61 can block the hot air flow from the connecting pipe 11 to enter the air inlet 52 at intervals, so that the hot air flow in the air duct 5 is blown out from each air outlet 51 at intervals, and the hot air flow intermittently blown toward the fruit and vegetable slices can temporarily blow the fruit and vegetable slices away from the supporting side wall 22, so that the hot air flow can dry the bottom surface of the fruit and vegetable slices while temporarily blowing the fruit and vegetable slices away from the supporting side wall 22, thereby effectively preventing the fruit and vegetable slices from sticking to the supporting side wall 22.

[0032] The implementation principle of a low-fat fruit and vegetable crisp processing device in Example 1 of the present application is as follows: the fruit and vegetable slices are placed on the inclined supporting side wall 22, and the fan blades 4 drive the cam 62 to rotate through the meshing driving gear 66 and the driven gear 67, thereby driving the air inlet baffle 61 to slide back and forth. During the reciprocating sliding process, the air inlet baffle 61 can block the hot air flow from the connecting pipe 11 to the air inlet 52 at intervals, so that the hot air flow in the air guide duct 5 is blown out from each air outlet 51 at intervals. The intermittent hot air flow blown toward the fruit and vegetable slices can temporarily blow the fruit and vegetable slices away from the supporting side wall 22. Example 2

[0033] The difference between Example 2 and Example 1 is that: Figure 5 and Figure 6 Each placement slot 21 includes two inclined supporting side walls 22, and the two supporting side walls 22 of the same placement slot 21 are inclined in opposite directions. At the same time, two groups of air ducts 5 are arranged under the storage plate 2, and each group of air ducts 5 is provided with a plurality of air ducts 5 arranged side by side, and are spaced apart along the depth direction of the box body 1. Each air duct 5 extends along the width direction of the box body 1, and each air duct 5 is provided with air outlets 51 corresponding to the number of the placement slots 21.

[0034] One of the two groups of air ducts 5 penetrates from the left side wall of the bracket 3, and the other group of air ducts 5 penetrates from the right side wall of the bracket 3. The air outlets 51 on the two groups of air ducts 5 correspond to the two supporting side walls 22 facing the same placement slot 21. The air ducts 5 belonging to the same group are provided with a common air inlet 52. The two air inlets 52 are respectively located on both sides of the bracket 3. The hot air blower simultaneously delivers hot air to the two air inlets 52 at intervals through the connecting pipe 11. Correspondingly, the sealing box 6 is also provided with two, distributed on both sides of the bracket 3, and the meshing driving gear 66 and the driven gear 67, as well as the cam 62, the driving rod 63, the return member 64 and the air inlet baffle 61 in the sealing box 6 are provided with two groups, distributed on both sides of the bracket 3. The blowing time of the two groups of air ducts 5 is different, that is, when one group of air ducts 5 is blowing, the other group of air ducts 5 is not blowing. The initial rotation position of the two groups of cams 62 can be adjusted so that the two groups of air inlet baffles 61 block their corresponding air inlets 52 at different times, thereby achieving the two groups of air ducts 5 blowing in sequence.

[0035] The fruit and vegetable slices are placed on one of the inclined supporting side walls 22, which also makes the fruit and vegetable slices inclined. The two groups of air ducts 5 block their corresponding air inlets 52 through two groups of air inlet baffles 61 respectively, and the two air inlets 52 are not connected or blocked at the same time, so that the two groups of air ducts 5 can blow out hot air flows at different times during operation, that is, the air outlets 51 corresponding to the two groups of air ducts 5 blow out hot air flows alternately, so that the fruit and vegetable slices can swing back and forth between the two supporting side walls 22 of the same placement groove 21 and turn over. In this way, while improving the drying effect, it can also further prevent the fruit and vegetable slices from sticking to the placement plate 2. Example 3

[0036] Example 3 of the present application discloses a low-fat fruit and vegetable crisps processing process, which uses the low-fat fruit and vegetable crisps processing device in Example 1 or Example 2 to produce and process fruit and vegetable slices, including the following steps: S1: Clean the freshly picked fruits and vegetables thoroughly in the cleaning unit to ensure that there is no agricultural pesticide residue on the surface of the fruits and vegetables; S2: The washed fruits and vegetables are sent to the slicing unit and sliced ​​into different sizes according to the types of fruits and vegetables; S3: The sliced ​​fruit and vegetable slices are placed in the box 1 for drying. First, the fruit and vegetable slices are laid flat on the inclined supporting side wall 22 of each placement groove 21 in turn, the box 1 is closed, and then the hot air blower is started. The hot air blower conveys hot air to the air inlet 52 corresponding to each group of air guide pipes 5 through the connecting pipe 11. While the hot air flow is used to dry the fruit and vegetable slices, the fruit and vegetable slices are temporarily blown away from the supporting side wall 22 where they are placed until they are completely dried.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
