Abstract
Description
A food processing drying device Technical Field
[0001] This utility model relates to the field of food drying technology, specifically a food processing drying device. Background Technology
[0002] Food processing drying equipment is used in the food processing industry to remove moisture from food to achieve purposes such as drying, preservation, and ease of storage and transportation. It typically uses heating modules to transfer heat to the food, causing the moisture in the food to absorb the heat and turn into water vapor, which is then exhausted through a ventilation system, thus achieving drying. Traditional drying ovens, for example, use heating elements to generate heat, which is then transferred to the food through the air inside the oven.
[0003] Common food processing and drying equipment on the market has many drawbacks. In terms of drying uniformity, traditional equipment causes uneven contact between the food and the hot air during the drying process because the food is placed on the tray. This results in some areas being overheated or over-dried, while others are not yet dried, reducing the stability of the dried food quality. Food placed at the top dries faster, while food at the bottom dries slower.
[0004] Secondly, the drums of commercially available drum-type food dryers are usually cylindrical. When food enters the drum, it will naturally gather towards the bottom of the drum under the action of gravity. If the drum diameter is large, the food will be distributed over a relatively wide area in the circumferential direction of the drum. During tumbling, the drop between food in different positions is large, which can easily cause food on top to fall onto food on bottom during tumbling, causing them to pile up. This not only affects the drying efficiency, but also causes uneven drying of the food, with some areas not drying properly due to the pile-up.
[0005] Finally, during the operation of drum-type food dryers on the market, if the rotation speed is too slow, the food will not be lifted high enough inside the drum, and the impact force when it falls will be small, which will not effectively break up the stacked food. If the rotation speed is too fast, the food will be subjected to a large centrifugal force inside the drum, and will stick tightly to the inner wall of the drum and rotate with the drum. There is not enough space for free tumbling, which is not conducive to the even spreading of the food.
[0006] Therefore, a food processing drying device is proposed. Summary of the Invention
[0007] The purpose of this invention is to provide a food processing and drying device to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a food processing and drying device, comprising a food drying chamber and a movable frame, wherein the movable frame is disposed outside the food drying chamber, and a moving component and a driving component are disposed on the top of the movable frame;
[0009] The moving component includes a set of sliding rods, which are slidably connected to the moving frame. There are three sets of sliding rods, with two in each set. A stabilizing plate is fixedly connected to the outer side of each set of sliding rods. A placement plate is fixedly connected to the top of the stabilizing plate. Trapezoidal deceleration blocks are arranged horizontally and equidistantly inside the placement plate. Three L-shaped relay blocks are fixedly connected to the outer wall of the stabilizing plate. A connecting plate set is fixedly connected to the outer wall of the moving frame.
[0010] Preferably, the driving assembly includes a positioning plate, which is fixedly connected to the outside of the movable frame. A trapezoidal slider is slidably connected to the top of the positioning plate, and a concave lever is fixedly connected to the outer wall of the trapezoidal slider. Limiting rings are symmetrically fixedly connected to the top of the positioning plate.
[0011] Preferably, the drive assembly further includes a cross-shaped slide bar, which is fixedly connected to the side of the trapezoidal slider away from the concave dial plate. A servo motor is fixedly connected to the top of the positioning plate, and a circular dial is fixedly connected to the output shaft of the servo motor.
[0012] Preferably, the movable frame has three equidistant limiting grooves, and the sliding rod assembly slides within the limiting grooves of the movable frame.
[0013] Preferably, the movable frame is connected by a connecting plate assembly.
[0014] Preferably, the end of the L-shaped relay block away from the stabilizing plate is in sliding engagement with the concave dial plate.
[0015] Preferably, the cross-shaped slide bar is slidably connected inside the limiting ring.
[0016] Preferably, the circular lever is slidably connected to the inside of the cross-shaped slide bar.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] By setting up the moving components, after the concave lever moves the L-shaped relay block, the L-shaped relay block will move the sliding rod assembly and the stabilizing plate along the top of the moving frame through the stabilizing plate. This causes the stabilizing plate to drive the placement tray to tilt back and forth, so that the food will slide back and forth synchronously along the top of the placement tray. This allows all parts of the food to have more opportunities to come into contact with hot air, avoiding local overheating or overdrying, or local undried conditions, ensuring uniform drying and improving product quality.
[0019] At the same time, the reciprocating tilting of the placement tray and the reciprocating sliding of the food can prevent the food from piling up on the placement tray, keeping the food in a relatively dispersed state, further promoting heat exchange, and helping to improve drying efficiency.
[0020] In addition, the concave structure can better cooperate with the L-shaped relay block, and can transmit power more accurately, ensuring that the L-shaped relay block moves accurately and stably when it is turned. Compared with the traditional flat plate, it has better guiding and positioning functions.
[0021] Finally, compared with traditional drum-type food dryers on the market, the above structure effectively avoids the phenomenon of food piling up during the drying process, while ensuring that the food is more dispersed during drying, thereby improving drying efficiency and ensuring a more uniform drying effect. With the trapezoidal deceleration block, the movement trajectory of the food is guided and restricted by the deceleration block, sliding on the placement tray according to a certain pattern, which is conducive to achieving more precise drying control, improving the consistency and stability of drying, and preventing food from colliding, squeezing or even rolling off the placement tray due to excessive rolling speed, thus achieving the purpose of flattening the food and improving the drying effect.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Example: As shown in Figures 1 to 3 and Figure 5, a food processing drying device includes a food drying chamber 11 and a movable frame 12. The food drying chamber 11 is equipped with a heating module group, which transfers heat to the food through the air inside the chamber. The moisture in the food absorbs the heat and is converted into water vapor, which is then discharged through the ventilation system, thereby achieving drying. The food drying chamber 11 is existing technology and will not be described in detail again. The bottom of the movable frame 12 is equipped with pulleys to assist the staff in moving the food. Three limiting grooves are equally spaced on the movable frame 12. The top of the movable frame 12 is equipped with a moving component and a driving component.
[0034] The moving assembly includes a sliding rod assembly 21, which is slidably connected to the moving frame 12. There are three sets of sliding rod assemblies 21, with two sliding rod assemblies in each set. The sliding rod assemblies 21 slide within the three limiting grooves of the moving frame 12, facilitating their movement. A stabilizing plate 22 is fixedly connected to the outer side of each sliding rod assembly 21. A placement plate 23 is fixedly connected to the top of the stabilizing plate 22. The spacing of the moving frame 12 is greater than the spacing between the sliding rod assembly 21, the stabilizing plate 22, and the placement plate 23 to avoid them from colliding with the moving frame 12 during movement. Trapezoidal deceleration blocks 24 are arranged horizontally and equidistantly inside the placement plate 23. An L-shaped relay block 25 is fixedly connected to the outer wall of the stabilizing plate 22, and there are three L-shaped relay blocks 25. A connecting plate assembly 26 is fixedly connected to the outer wall of the moving frame 12 for connecting the moving frame 12.
[0035] As shown in Figures 4, 6, and 7, the drive assembly includes a positioning plate 31, which is fixedly connected to the outside of the movable frame 12. A trapezoidal slider 32 is slidably connected to the top of the positioning plate 31, and a concave lever 33 is fixedly connected to the outer wall of the trapezoidal slider 32. The end of the L-shaped relay block 25 away from the stabilizing plate 22 is slidably engaged with the concave lever 33. A limit ring 35 is symmetrically fixedly connected to the top of the positioning plate 31, and a cross-shaped slide rod 34 is slidably connected inside the limit ring 35.
[0036] The drive assembly also includes a cross-shaped slide bar 34, which is fixedly connected to the trapezoidal slider 32 on the side away from the concave dial plate 33. A servo motor 36 is fixedly connected to the top of the positioning plate 31. A circular dial 37 is fixedly connected to the output shaft of the servo motor 36, and the circular dial 37 is slidably connected to the inside of the cross-shaped slide bar 34 to drive the cross-shaped slide bar 34 to reciprocate along the inside of the limiting ring 35.
[0037] Based on the above preferred embodiments, the following is the complete working process and working principle of the above embodiments:
[0038] Preparation before drying:
[0039] Before drying the food, the staff first need to place the food on the top of the placement tray 23 in sequence, and then push the moving rack 12 and the moving assembly into the food drying chamber 11.
[0040] Drying steps:
[0041] After the mobile frame 12 and the mobile assembly are pushed into the food drying chamber 11, the staff will activate the heating module group inside the food drying chamber 11. This will cause the moisture in the food to absorb heat and be converted into water vapor, which will then be discharged through the ventilation system, thereby drying the food.
[0042] At the same time, when the staff starts the heating module group inside the food drying chamber 11, the staff needs to start the servo motor 36 simultaneously. Then the servo motor 36 will drive the circular dial 37 to rotate. The rotating circular dial 37 will move the cross-shaped slide bar 34 back and forth along the inside of the limiting ring 35 through the columnar protrusion.
[0043] During the horizontal reciprocating sliding of the cross-shaped slide bar 34, the cross-shaped slide bar 34 will drive the trapezoidal slider 32 to slide horizontally and reciprocatingly along the top groove of the positioning plate 31. During the sliding of the trapezoidal slider 32, the L-shaped relay block 25 will be moved by the concave dial plate 33. It can be seen that the length of the limiting groove on the moving frame 12 is greater than the length of the stabilizing plate 22. As a result, the L-shaped relay block 25 will first drive the stabilizing plate 22 to abut against one side of the upper limit groove of the moving frame 12. As the concave dial plate 33 continues to abut the L-shaped relay block 25, the L-shaped relay block 25 will then drive the stabilizing plate 22 to rotate and tilt with the end of the slide bar assembly 21 that abuts against the upper limit groove of the moving frame 12 as the center point.
[0044] Similar to the above-mentioned movement process, after the L-shaped relay block 25 causes the stabilizing plate 22 to contact the other side of the moving frame 12, the concave lever 33 continues to move the L-shaped relay block 25. Subsequently, the L-shaped relay block 25 will cause the stabilizing plate 22 to tilt. The concave structure of the concave lever 33 can better cooperate with the L-shaped relay block, and can transmit power more accurately, ensuring that the L-shaped relay block moves accurately and stably when it is moved. Compared with the traditional flat lever, it has a better guiding and positioning function.
[0045] When the stabilizing plate 22 is tilted, the stabilizing plate 22 will drive the top placement tray 23 to tilt synchronously, causing the food on the top of the placement tray 23 to roll along the inside of the placement tray 23, thereby allowing all parts of the food to have more opportunities to come into contact with hot air, avoiding local overheating or overdrying, or local undried conditions, ensuring the uniformity of the drying process and improving product quality.
[0046] Secondly, the reciprocating tilting of the placement tray 23 and the reciprocating sliding of the food can prevent the food from piling up on the placement tray 23, keeping the food in a relatively dispersed state, further promoting heat exchange, and helping to improve drying efficiency.
[0047] Finally, in traditional food processing and drying devices, food slides freely on the placement tray 23, and its movement trajectory is difficult to control. However, the above structure effectively avoids the phenomenon of food piling up during the drying process, and at the same time ensures that the food is more dispersed during drying. After setting the trapezoidal deceleration block 24, the movement trajectory of the food will be guided and restricted by the deceleration block, and it will roll on the placement tray 23 according to a certain pattern. This is conducive to achieving more precise drying control, improving the consistency and stability of drying, and at the same time preventing food from colliding, squeezing or even rolling off the placement tray 23 due to excessive rolling speed. This achieves the purpose of spreading the food flat and improves the drying effect.
[0048] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
