Description

Technical Field

[0001] The invention relates to the technical field of puffed food drying, in particular to a temperature self-adapting drying device and a drying method for puffed food processing. Background Art

[0002] Puffed food is a new type of food, which uses cereals, potatoes, beans and other foods with low water content as the main raw materials. After pressurization and heating, the raw materials expand their volume, and then are processed and formed. This type of food has a porous and fluffy structure, a crispy and sweet taste, and has certain nutritional value.

[0003] In the production process of puffed food, drying is an important production process. Drying can remove excess moisture in the puffed food and improve the taste and storage time of the puffed food.

[0004] Most of the existing puffed food drying devices use tunnel dryers. During drying, the puffed food is transported to the tunnel dryer by a conveying device to complete the drying operation. This has a more obvious drying effect for some thinner puffed foods such as potato chips, but the drying effect is relatively general for thicker puffed foods such as French fries. This is mainly because the thickness of such puffed foods is relatively thick, and the temperature is often not transmitted to the inside or the temperature inside is relatively low. In addition, when such puffed foods are in a slightly stacked state, it is more difficult to achieve a better drying effect, which affects the drying effect of such puffed foods. Summary of the invention

[0005] The object of the present invention is to provide a temperature adaptive drying device and a drying method for puffed food processing, so as to solve the problems raised in the above-mentioned background technology.

[0009] As a further solution of the present invention: the limiting assembly includes a limiting member arranged on the shovel plate and an abutment plate slidably connected to the limiting member, and the abutment plate is connected to the shovel plate through a spring; the limiting wheel is located between the limiting member and the abutment plate, and the limiting wheel is rotatably connected to the pulling rod rotatably installed on the connecting rod; the limiting member is provided with two groups of limiting grooves on one side facing the abutment plate, the limiting grooves form the buffer position, and the two groups of limiting grooves are connected by a guide plane.

[0010] As a further solution of the present invention: the trigger structure includes a trigger member arranged on the inner wall of the drying box and a follower rod fixedly connected to the rotating shaft of the shovel plate, and a trigger shaft is arranged at one end of the follower rod away from its rotation center. The trigger shaft cooperates with the trigger member and can drive the shovel plate to deflect when the shovel plate moves to the end of the stroke.

[0011] As a further solution of the present invention: the driving assembly includes a bracket connected to the drying box, a transverse rod is slidably installed on the bracket, and the transverse rod is slidably connected to the connecting rod; the driving assembly also includes a linear driving module connected to the bracket and a guide plate arranged in the drying box, the linear driving module is connected to a driving frame, and the driving frame is provided with an abutment groove; a guide groove is provided on the guide plate, and a coaxial wheel set installed on the connecting rod cooperates with the abutment groove and the guide groove, so as to drive the shovel plate to perform a lifting action when the shovel plate moves to the end of the stroke.

[0012] As a further solution of the present invention: the abutment groove includes a triangular hollow structure opened on the driving frame, and two groups of symmetrically arranged inclined guide surfaces are formed in the triangular hollow structure; the guide groove includes a horizontal groove arranged along the length direction of the guide plate, and vertical grooves are connected on both sides of the horizontal groove.

[0014] A drying method, using the temperature adaptive drying device for puffed food processing, comprises the following steps:

[0015] Step 1: Place the puffed food to be dried in the storage tank, and connect the external high-temperature gas pumping device to the air supply pipe;

[0016] Step 2: Start the driving assembly to make the shovel plate fit with the upper surface of the storage tank, then move the shovel plate horizontally and scoop up the puffed food in cooperation with the vertical plate;

[0017] Step 3: When the shovel plate moves to the end of the stroke, the trigger structure triggers the shovel plate to deflect, so that the puffed food on the shovel plate can slide from the other end of the shovel plate into the storage tank, and in the process of sliding, the puffed food can contact with the high-temperature gas;

[0018] Step 4: The shovel plate continues to move, and under the action of the driving component, the shovel plate moves upward. At this time, the shovel plate can shake due to the vertical movement force generated, so that the separation rate of the puffed food and the shovel plate is higher;

[0019] Step 5: The driving component drives the shovel to move in the opposite direction, and at the same time, the flow direction of the high-temperature gas in the drying box changes;

[0020] Step 6: Repeat steps 1 to 5 above until the puffed food is completely dried.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: firstly, the shovel plate can maintain a stable tilted state through the provided limit assembly and trigger structure, so that the puffed food can be scooped up when the shovel plate moves laterally; secondly, when the shovel plate moves to the end of the stroke, the shovel plate can tilt in the opposite direction, so that the scooped puffed food can slide down from the other side of the shovel plate, thereby achieving the effect of repeatedly turning over the puffed food, and cooperating with the conveying direction of the high-temperature gas to improve the drying effect of the puffed food; on the one hand, the air supply pipe, the conversion sleeve and the power structure can be provided, so that the puffed food can be heated. On the one hand, the drying effect is improved, and on the other hand, the temperature in the drying box can be more balanced, so as to avoid the phenomenon that the drying degree of the puffed food in the drying box is inconsistent due to heat loss. At the same time, the high-temperature gas can collide with the puffed food in the sliding state under the guidance of the shovel in the inclined state, so as to improve the drying effect of the puffed food. When the puffed food falls into the storage tank, the high-temperature gas can continue to act on the puffed food in the storage tank, and can continue to dry it, so that the puffed food can be accumulated on one side of the storage tank, so as to avoid the puffed food from being dried when the shovel descends and moves in the reverse direction. When the shovel moves, the puffed food in the storage tank is squeezed, causing the puffed food to be damaged, thereby improving the yield rate of the puffed food after drying; through the set driving component, when the movement direction of the shovel plate changes, the shovel plate can produce an effect of assisting the separation of the puffed food from the shovel plate under the cooperation of the inertial force and the limit component, thereby improving the separation rate of the puffed food from the shovel plate, avoiding the puffed food from adhering to the shovel plate and being unable to be dried, and ensuring the cyclic flipping effect of the puffed food during the shovel plate action process; a temperature sensor is arranged outside the drying box, which can detect the high temperature flowing out of the drying box. The temperature of the gas is controlled in real time, and the temperature of the high-temperature gas pumped by the external high-temperature gas pumping device is controlled in real time to prevent the gas with too high temperature from being transported into the drying box all the time, which may cause the puffed food to gelatinize. At the same time, the air supply pipe at the end is only provided with an air outlet on one side facing the middle of the drying box, thereby avoiding the high-temperature gas from directly acting on the temperature sensor after coming out of the air supply pipe without heat exchange with the puffed food, which may cause the temperature of the high-temperature gas to be adjusted too low and affect the drying effect. The temperature in the drying box is adaptively controlled to ensure that the temperature in the drying box remains relatively constant, so as to improve the drying effect.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0036] See also Figure 1 to Figure 11 In an embodiment of the present invention, a temperature adaptive drying device for puffed food processing includes a drying box 1, a connecting rod 6, a limit assembly, a trigger structure, a driving assembly, and also includes an air supply pipe 25, a conversion sleeve 24 and a power structure.

[0037] There are multiple groups of air supply pipes 25 installed in the drying box 1 and located on the upper part of the vertical plate 1901. Two groups of air outlets 2501 are circumferentially opened on the air supply pipes 25; the conversion sleeve 24 is sealed and rotatably fitted with the air supply pipes 25, and the conversion sleeve 24 is provided with a conducting hole 2401 adapted to the air outlet 2501. When the conducting hole 2401 coincides with the air outlet 2501, high-temperature gas can enter the drying box 1 through the conducting hole 2401 and the air outlet 2501.

[0038] In this embodiment, the external high-temperature gas pumping device is connected to the air supply pipe 25, so that when the puffed food is dried, the high-temperature gas can enter the drying box 1 through the air outlet 2501 on the air supply pipe 25, and because the air supply pipe 25 is equidistantly arranged with the vertical plate 1901, the high-temperature gas flowing out of the air outlet 2501 can act on the puffed food to be dried in sections. On the one hand, the puffed food can be heated more evenly and the drying effect can be improved. On the other hand, the temperature in the drying box 1 can be more balanced, avoiding the phenomenon of inconsistent drying degree of the puffed food in the drying box 1 due to heat loss.

[0039] The power structure is connected to the conversion sleeve 24, and the power structure can drive the conversion sleeve 24 to rotate relative to the air supply pipe 25. The power structure includes a gear 23 coaxially fixedly connected to the conversion sleeve 24 and a segmented rack plate 21 arranged outside the drying box 1, and the segmented rack plate 21 is formed with teeth meshing with the gear 23; the segmented rack plate 21 is rollingly connected to the guide member 22 arranged on the drying box 1, and the segmented rack plate 21 is connected to the electric telescopic rod 20 arranged on the drying box 1; a receiving plate 19 is arranged in the drying box 1, and the receiving plate 19 is divided by a vertical plate 1901 to form a plurality of storage slots, wherein the vertical plate 1901 is provided with a plurality of holes for high-temperature gas to pass through; the connecting rod 6 is arranged at the upper part of the storage slot, and a shovel plate 18 is rotatably installed on the connecting rod 6, wherein a plurality of connecting rods 6 are provided, and the plurality of connecting rods 6 are connected by a connecting plate 26.

[0040] In the present invention, the shovel board 18 always has a state of being inclined toward its movement direction, and the shovel board 18 can perform a lifting action so that the scooped puffed food can slide back into the storage tank (described in detail below). In this embodiment, the flow direction of the high-temperature gas entering the drying box 1 through the air supply pipe 25 can change with the change of the movement direction of the shovel board 18. Specifically, when the shovel board 18 tilts in one direction, the puffed food placed in the storage tank can be scooped up, and then the shovel board 18 will move upward, so that the separation rate of the puffed food on the shovel board 18 and the shovel board 18 is higher, and at this time, the conducting hole 2401 on the conversion sleeve 24 and the air supply pipe 25 are connected. One of the groups of air outlets 2501 on the upper surface overlaps, so that the high-temperature gas enters the drying box 1, and the high-temperature gas can move downwardly under the guidance of the shovel plate 18 in an inclined state, so that the high-temperature gas can collide with the puffed food in a sliding state, thereby improving the drying effect of the puffed food, and when the puffed food falls into the storage tank, the high-temperature gas can continue to act on the puffed food in the storage tank, and can continue to dry it while allowing the puffed food to be accumulated on one side of the storage tank, so as to avoid squeezing the puffed food in the storage tank when the shovel plate 18 descends and moves in the reverse direction, causing damage to the puffed food, thereby improving the yield rate of the puffed food after drying.

[0041] Furthermore, when the shovel plate 18 moves in the opposite direction to scoop up the puffed food and then deflects in the opposite direction again, the electric telescopic rod 20 will move to drive the segmented rack plate 21 to move laterally. At this time, with the cooperation of the teeth and the gear 23, the conversion sleeve 24 can rotate relative to the air supply pipe 25, so that another group of air outlets 2501 on the air supply pipe 25 is connected, thereby changing the flow direction of the high-temperature gas and matching it with the sliding direction of the puffed food, thereby achieving the same effect as above, that is, the high-temperature gas can remain directional and be used for puffed food, thereby realizing continuous drying of the puffed food and further improving the drying effect.

[0042] It should be noted that a temperature sensor is provided on the outside of the drying box 1, and the temperature sensor can detect the temperature of the high-temperature gas flowing out of the drying box 1, and control the temperature of the high-temperature gas pumped by the external high-temperature gas pumping device in real time, so as to prevent the excessively high-temperature gas from being transported into the drying box 1 all the time, causing the puffed food to gelatinize. At the same time, the air supply pipe 25 located at the end is only provided with an air outlet 2501 on one side facing the middle of the drying box 1, thereby avoiding the high-temperature gas from not exchanging heat with the puffed food after coming out of the air supply pipe 25 and directly acting on the temperature sensor, causing the temperature of the high-temperature gas to be adjusted too low and affecting the drying effect, so as to adaptively control the temperature in the drying box 1 to ensure that the temperature in the drying box 1 remains relatively constant, so as to improve the drying effect.

[0043] See also Figure 3 , Figure 7~Figure 9 The limiting assembly is installed on the shovel plate 18, and two groups of buffer positions are formed on the limiting assembly. The limiting wheel 11 connected to the connecting rod 6 can switch between the two groups of buffer positions to convert the deflection direction of the shovel plate 18; the limiting assembly includes a limiting member 12 arranged on the shovel plate 18 and an abutment plate 13 slidably connected to the limiting member 12, and the abutment plate 13 is connected to the shovel plate 18 through a spring 14. Specifically, a telescopic shaft is arranged on the abutment plate 13, and a The guide hole is configured such that the telescopic shaft can slide in the guide hole, so that the abutment plate 13 can maintain a state parallel to the shovel plate 18; the limiting wheel 11 is located between the limiting member 12 and the abutment plate 13, and the limiting wheel 11 is rotatably connected to the pulling rod 10 rotatably mounted on the connecting rod 6; the limiting member 12 is provided with two groups of limiting grooves 1202 on one side facing the abutment plate 13, the limiting grooves 1202 form the buffer position, and the two groups of limiting grooves 1202 are connected by a guiding plane 1201.

[0044] In the initial state, the limiting wheel 11 is in one group of limiting grooves 1202, and the limiting wheel 11 is limited in the group of limiting grooves 1202 by the abutment plate 13. The limiting wheel 11 is connected to the connecting rod 6 through the pulling rod 10, so that the shovel plate 18 can maintain a stable inclined state, and when the lower end of the shovel plate 18 is attached to the upper surface of the storage tank and moves laterally, it can cooperate with the vertical plate 1901, so that the puffed food in the storage tank can be shoveled onto the shovel plate 18.

[0045] When the shovel plate 18 is triggered by the trigger structure and deflected, the limiting wheel 11 is pulled by the pulling rod 10. At this time, the limiting wheel 11 can be separated from the limiting groove 1202 and push the abutment plate 13 upward, so that the spring 14 is stretched and the limiting wheel 11 can move along the guide plane 1201. When the limiting wheel 11 moves along the guide plane 1201 to another limiting groove 1202, the limiting wheel 11 can be restricted again. At this time, the shovel plate 18 realizes reverse deflection, so that when the shovel plate 18 moves in the opposite direction, its lower end can fit with the upper surface of the storage tank again, thereby scooping up the puffed food.

[0046] It should also be noted that the two sides of the limit groove 1202 are inclined, which can be simply understood as an inverted "eight" structure of the limit groove 1202, so that when the limit wheel 11 switches from the guide plane 1201 to the limit groove 1202, on the one hand, the shovel plate 18 can be slowly deflected to prevent the shovel plate 18 from deflecting too fast at the end of the deflection, which will scoop up the puffed food and cause the puffed food to be damaged by collision during the falling process, thereby further improving the yield rate. On the other hand, in the process of switching the shovel plate 18 from the horizontal direction to the vertical direction, the shovel plate 18 can produce reciprocating deflection and shaking to improve the separation rate of the puffed food and the shovel plate 18.

[0047] The trigger structure is connected to the rotating shaft of the shovel plate 18. When the shovel plate 18 moves to the end of its stroke, the trigger structure can actively deflect the shovel plate 18 and switch the limiting wheel 11 from one group of buffer positions to another group of buffer positions; the trigger structure includes a trigger member 17 arranged on the inner wall of the drying box 1 and a follower rod 15 fixedly connected to the rotating shaft of the shovel plate 18, and a trigger shaft 16 is arranged at one end of the follower rod 15 away from its rotation center. The trigger shaft 16 cooperates with the trigger member 17 and can drive the shovel plate 18 to deflect when the shovel plate 18 moves to the end of its stroke.

[0048] In the present embodiment, when the shovel plate 18 moves laterally to scoop up the puffed food, when the shovel plate 18 moves to the end of the stroke, the trigger shaft 16 can abut against the trigger member 17 on one side, so that the follower rod 15 drives the shovel plate 18 to deflect, and the inclination direction of the shovel plate 18 changes, so that the scooped puffed food can slide back into the storage tank through the other side of the shovel plate 18. Similarly, when the shovel plate 18 moves in the opposite direction, the above process can be repeated, that is, during the reciprocating motion of the shovel plate 18, it has a reciprocating deflection state, and can scoop up the puffed food and then make the puffed food fall back into the storage tank, thereby realizing the reciprocating turning of the puffed food and coordinating with the conveying direction of the high-temperature gas to improve the drying effect of the puffed food.

[0049] See also Figure 3~Figure 6, the driving assembly is connected to the connecting rod 6, and the driving assembly can make the connecting rod 6 perform a lifting action when the shovel plate 18 moves to the end of the stroke; the driving assembly includes a bracket 2 connected to the drying box 1, and a transverse rod 7 is slidably installed on the bracket 2, and the transverse rod 7 is slidably connected to the connecting rod 6; the driving assembly also includes a linear driving module 3 connected to the bracket 2 and a guide plate 5 arranged in the drying box 1, the linear driving module 3 is connected to a driving frame 4, and an abutment groove is provided on the driving frame 4, and the abutment groove includes a triangular hollow structure opened on the driving frame 4, and the triangular hollow structure Two groups of symmetrically arranged inclined guide surfaces 401 are formed in the hollow structure; a guide groove is arranged on the guide plate 5, and a coaxial wheel group installed on the connecting rod 6 cooperates with the abutment groove and the guide groove, so that when the shovel plate 18 moves to the end of the stroke, the shovel plate 18 can be driven to perform a lifting action, wherein the guide groove includes a horizontal groove 501 arranged along the length direction of the guide plate 5, and vertical grooves 502 are connected to both sides of the horizontal groove 501; the coaxial wheel group includes an interlocking wheel 8 and a groove wheel 9 connected to the connecting rod 6 and coaxially arranged, the interlocking wheel 8 is adapted to the abutment groove, and the groove wheel 9 can roll in the guide groove.

[0050] In the initial state, the shovel plate 18 is in an inclined state with the lower end away from the upper surface of the storage tank. At this time, the groove wheel 9 is at the upper end of one group of vertical grooves 502, and the engaging wheel 8 is in contact with the side of one group of inclined guide surfaces 401 (see Figure 6), and when the linear drive module 3 is in action, it can drive the driving frame 4 to move along the length direction of the bracket 2, and enable the engaging wheel 8 to move along the above-mentioned inclined guide surface 401. At this time, the groove wheel 9 moves downward along the above-mentioned vertical groove 502, so that the connecting rod 6 can move downward. When the lower end of the shovel plate 18 is in contact with the upper surface of the storage groove, the groove wheel 9 moves to the lower end of the vertical groove 502, and the engaging wheel 8 moves to the lower end of the two groups of inclined guide surfaces 401. Then the driving frame 4 continues to move laterally, so that the groove wheel 9 can move along the horizontal groove 501. At this time, the shovel plate 18 will move laterally and scoop up the puffed food. After the groove wheel 9 moves to the end of the horizontal groove 501, the driving frame 4 continues to move. At this time, the engaging wheel 8 can abut against another group of inclined guide surfaces 401, and enable the groove wheel 9 to move upward along the other vertical groove 502. This process During the process, the shovel board 18 can move upward, and when the shovel board 18 switches from horizontal movement to vertical movement, the shovel board 18 has achieved a change in the tilting direction, and the puffed food moves toward the lower end of the shovel board 18 that switches the tilting direction (the center of gravity of the shovel board 18 has changed), and when the shovel board 18 moves vertically, the shovel board 18 will maintain its original state due to inertia. At this time, the limiting wheel 11 can roll slightly in the limiting groove 1202, so that during the rising process of the shovel board 18, the shovel board 18 has a reciprocating deflection along its rotating axis. During this process, an effect of assisting the separation of the puffed food from the shovel board 18 can be generated, thereby improving the separation rate of the puffed food from the shovel board 18, avoiding the puffed food from adhering to the shovel board 18 and being unable to be dried, and ensuring the cyclic flipping effect of the puffed food during the movement of the shovel board 18.

[0051] It should also be noted that in order to further improve the separation rate of the puffed food and the shovel plate 18, the driving speed of the linear drive module 3 can be changed during the rising process of the shovel plate 18 to increase the duration of the reciprocating deflection of the shovel plate 18 during the rising process.

[0052] As an embodiment of the present invention, a drying method is also proposed, which uses the temperature adaptive drying device for puffed food processing, comprising the following steps:

[0053] Step 1: Place the puffed food to be dried in the storage tank, and connect the external high-temperature gas pumping device to the air supply pipe 25;

[0054] Step 2: Start the driving assembly to make the shovel plate 18 fit with the upper surface of the storage tank, then the shovel plate 18 moves horizontally and scoops up the puffed food in cooperation with the vertical plate 1901;

[0055] Step 3: When the shovel plate 18 moves to the end of the stroke, the trigger structure triggers the shovel plate 18 to deflect, so that the puffed food on the shovel plate 18 can slide from the other end of the shovel plate 18 into the storage tank, and in the process of sliding, the puffed food can contact with the high-temperature gas;

[0056] Step 4: The shovel board 18 continues to move, and under the action of the driving assembly, the shovel board 18 moves upward. At this time, the shovel board 18 generates a vertical movement force, so that the shovel board 18 can shake, so that the separation rate of the puffed food and the shovel board 18 is higher;

[0057] Step 5: The driving assembly drives the shovel plate 18 to move in the reverse direction, and at the same time, the flow direction of the high-temperature gas in the drying box 1 changes;

[0058] Step 6: Repeat steps 1 to 5 above until the puffed food is completely dried.
