Description

Technical Field

[0001] The invention relates to the technical field of tsaoko drying, and in particular to a tsaoko drying device. Background Art

[0002] In the process of drying the tsaoko, specific drying stages usually refer to different drying periods divided according to the characteristics of the tsaoko and the drying process requirements. These stages are designed to ensure that the tsaoko can be dried evenly and quickly while maintaining its good quality and nutritional content. The tsaoko drying process is generally as follows:

[0003] The first stage requires preheating

[0004] The preheating stage is mainly to balance the temperature inside and outside the fruit, so that the fruit can gradually adapt to the environment in the drying room and avoid sudden high temperature damage to the fruit. In this stage, the temperature in the drying room will gradually increase to a lower level (such as 35℃-40℃), while maintaining a low humidity to prevent the fruit from crusting prematurely or the internal moisture from being unable to be discharged. The preheating time is 2-3 hours.

[0005] The second stage is the drying stage

[0006] During the drying process, the grass fruit begins to evaporate a large amount of water while maintaining its internal nutrients and color. At this stage, the temperature of the drying room will be further increased to an appropriate range (such as 40℃-45℃), and the dehumidification system will be turned on to control the humidity in the drying room. This stage usually takes a long time (such as 8 hours) to ensure that the grass fruit can be evenly heated and a large amount of water can be discharged.

[0007] The third stage is the deep drying stage

[0008] The deep drying stage is to further remove the moisture inside the cardamom while maintaining the stability of its shape and color. At this stage, the temperature of the drying room will be relatively high (such as 50℃-55℃) to accelerate the evaporation of the moisture inside the cardamom. At the same time, the dehumidification system will continue to work to keep the humidity in the drying room at a low level. This stage usually takes a long time (such as 10 hours) to ensure that the cardamom can be completely dried.

[0009] During the above drying operation in the existing drying room, the applicant found that since the racks are randomly placed, the drying operation is realized only by the temperature in the drying room. In the first and second stages, moisture is mainly discharged. Therefore, the temperature control is very strict to avoid premature crusting. At the drying stage, a large amount of internal moisture needs to be discharged. The existing open drying method in a closed space has the following defects:

[0010] First, each stage takes a long time, and the heat concentration is uneven, resulting in differences in the preheating stage and the drying stage, which makes the drying effect of the internal grass fruit asynchronous;

[0011] Second, the wind force generated by the drying device causes the heat to flow inside. The cardamom close to the heat source is subjected to concentrated heat in the later stage, and the small particles are easily brittle, resulting in a decrease in the qualified rate.

[0045] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0046] Reference Figures 1 to 13 The present invention provides a tsaoko drying device, comprising:

[0047] A drying room 1 is provided with a shelf rail 2 and a hydraulic adjustment device 3 corresponding to the shelf rail 2. The hydraulic adjustment device 3 is provided on the inner side of the double door of the drying room 1. The shelf rail 2 has a transverse slide rail part for moving the placement rack upward. Of course, the bottom of the placement rack is provided with a roller limited to the transverse slide rail part, and an edge limit baffle plate vertically provided with the transverse slide rail part. The edge limit baffle plate is in contact with the movable avoidance rack 4. A dehumidification system 7 is also provided on the top of the drying room 1. According to the requirements of the drying process, the internal moisture can be quickly discharged. A plurality of groups of hot air blowers 6 are provided in the direction toward the shelf rail 2, and the temperature of the hot air blowers 6 is adjustable;

[0048] The placing rack is placed on the shelf guide rail 2, and multiple placing racks are placed side by side on the shelf guide rail 2 and limited by the hydraulic adjustment device 3. The piston end of the hydraulic adjustment device 3 is provided with a contact plate, and the contact plate contacts with the movable avoidance frame 4 on the placing rack through the movable end of the hydraulic adjustment device 3, so that it is placed regularly on the shelf guide rail 2 to prevent unstable placement. The hydraulic adjustment device 3 has a first telescopic station and a second telescopic station. The placing rack includes a stabilizing frame 8, and a movable avoidance frame 4 elastically arranged on the stabilizing frame 8 and capable of moving closer to and away from each other. The stabilizing frame 8 includes a movable bottom plate 81, and a U-shaped groove is arranged on the movable bottom plate 81. The movable avoidance frame 4 is elastically arranged in the U-shaped groove by a compression spring 82. When the movable avoidance frames 4 on both sides are squeezed by both sides When force is applied, the two movable avoidance frames 4 will slide in the U-shaped groove, and the compression spring 82 will be compressed, so that the movable avoidance frames 4 on both sides will abut against the movable bottom plate 81, and the adjacent two side placement frames will be close together, and the supporting frames 9 will be spliced, and the multiple horizontal trays 5 and the supporting frames 9 on both sides of the trays 5 will form a contact state. At this time, after the side panels 10 fall down, they will form a closed channel with the multiple horizontal trays 5 on the upper side and the supporting frames 9 on both sides of the trays 5. It should be noted about the closed channel that since the length of the side panels 10 cannot include the length of both sides of the tray 5, there is a gap between the two adjacent side panels 10, and after the two contacting movable avoidance frames 4 are closed, the gap between the two side panels 10 can be filled, which is beneficial to the airflow during the guiding process and can reduce heat loss.

[0049] It should be noted that the guide crossbeam 83 is inserted into the transverse cavity of the movable avoidance frame 4, and the guide crossbeam 83 is fixedly connected to the vertical rod 85 through the connecting block 84. The vertical rod 85 is located in the vertical cavity of the movable avoidance frame 4, and the guide crossbeam 83 is equivalent to a positioning slide bar. The movable avoidance frame 4 moves on the positioning slide bar, thereby ensuring stability, so that during the overall approach process, the movable avoidance frame 4 will not shake. The bottom of the vertical rod 85 is fixedly connected to the connecting block 84, and the vertical rod 85 is fixedly set, and when the two movable avoidance frames 4 are in a distant state, the vertical rod 85 is attached to one side of the inner wall of the movable avoidance frame 4, and when the two movable avoidance frames 4 move close to each other, the other side of the vertical rod 85 is attached to the other side of the inner wall of the movable avoidance frame 4.

[0050] It is important to emphasize that a base is provided between the top of the movable bottom plate 81 and the lowest tray 5. The function of the base is to limit the downward movement of the tray 5 and provide necessary support. After drying, the multiple trays 5 are in a stacked state, so the base provided directly below the tray 5 effectively prevents the stacked trays 5 from tipping over.

[0051] like Figures 7 to 9The support bracket 9 shown is arranged on the stabilizing frame 8, and both ends thereof pass through the avoidance grooves 41 arranged on the movable avoidance frame 4. When the movable end of the hydraulic adjustment device 3 is located at the first working position, the movable avoidance frame 4 on the same placement frame is in a separated state, and the support bracket 9 is in a horizontal state. When the movable end of the hydraulic adjustment device 3 is located at the second working position, the movable avoidance frame 4 on the same placement frame is in a close state, and the support bracket 9 is in a vertical state.

[0052] It needs to be explained that the support frame 9 is used to support the tray 5, and there is a support frame 9 on both sides of each tray 5. When the movable avoidance frames 4 on both sides are brought together, the offset grooves 43 on the front and rear sides first drive the two trigger members on the support frame 9 to gradually move together, and then the pressure of the movement together makes the two correction members move together, while the tray 5 can be corrected in the width direction, so that the multiple trays 5 in the horizontal direction are kept on the same horizontal line, so that the air duct is in a horizontal state and the air duct will not deviate.

[0053] In the specific implementation process, the support frame 9 includes a load-bearing rod that passes through the avoidance groove 41 on the front and rear sides, and the load-bearing rod includes a fixed rod 91A. Rotating rods 91 are arranged on both sides of the fixed rod 91A through torsion springs. The rotating rod 91 is arranged on the trigger member, and one end of the rotating rod 91 is fixedly connected to a gear 92. A short rack 42 is arranged above the tail end of the avoidance groove 41, and the short rack 42 is located on the path of the gear 92. In the process of moving the movable avoidance frame 4, first, the offset groove 43 drives the two trigger members on the support frame 9 to gradually get closer. When the gear 92 is engaged with the short rack 42, the rotating rod 91 can be rotated. Since a splicing plate 918 and an adapting sleeve 919 that fits the splicing plate 918 are designed, and the adapting sleeve 919 cooperates with the guide shaft 917 through a spiral groove, of course, a splicing plate 918 can be set between the spiral grooves. The torsion spring can limit the fixed rod 91A by the splicing plate 918 during the rotation of the rotating rod 91, so that the splicing plate 918 always maintains a horizontal state, so that when two adjacent splicing plates 918 are in contact, a horizontal state can be formed. It should be further explained that the splicing plate 918 can be elastically stretched in the width direction, so that an adjustment margin can be reserved. When approaching, that is, before the gear 92 and the short rack 42 are engaged, the two adjacent splicing plates 918 are first in contact, and then through the friction force after contact, when the gear 92 and the short rack 42 are engaged, it can further ensure that the two adjacent splicing plates 918 are in a horizontal state and will not rotate. In addition, in the above-mentioned effects, the error generated when the movable avoidance frame 4 is approached can also be compensated by the splicing plate 918.

[0054] It is further explained that the trigger member is arranged at both ends of the load-bearing rod and slides horizontally in the avoidance groove 41. The trigger member includes a sleeve groove 96 arranged on the slider 94. The upper and lower sides of the slider 94 are respectively in contact with the upper and lower sides of the inner wall of the avoidance groove 41 or a small gap is reserved. In this way, when the movable avoidance frame 4 moves, the slider 94 can maintain a stable state, so that the tray 5 as a whole remains stable. A displacement member 95 is elastically arranged on the sleeve groove 96. The upper and lower sides of the displacement member 95 are fixedly connected to a guide rod 97. The guide rod 97 is inserted into the offset groove 43 opened on the inner wall of the avoidance groove 41. The outer side of the displacement member 95 is fixedly connected to an independent sleeve 98 attached to one side of the slider 94. One side of the independent sleeve 98 is fixedly connected to a flower axis 99, a splicing plate 918 fixedly arranged on the load-bearing rod, a correction member located on both sides of the splicing plate 918 and axially movable on the load-bearing rod, a guide slide rail fixedly connected to one side of the trigger member, and the guide slide rail is sleeved on the load-bearing rod.

[0055] Specifically, when the movable avoidance frame 4 moves, the offset groove 43 is a 120-degree groove. When the guide rod 97 moves in the offset groove 43, the guide rod 97 drives the displacement member 95 to move out of the sleeve groove 96. In this way, the independent sleeve 98 and the flower shaft 99 fixed to the displacement member 95 both slide axially on the rotating rod 91. It should be noted that the correction member includes a correction bar 914, and a slide groove opening 915 is provided on the correction bar 914. The uppermost position of the slide groove opening 915 is as shown in FIG. Fig. 9In the state shown, a card slot is provided at the slot opening 915 and the sliding rod 913, which is used to limit the sliding rod 913 and stably suspend the support frame 920. The correction bar 914 is rotatably connected to the outer side of the flower shaft 99, and the sliding rod 913 is penetrated by the slot opening 915. One end of the sliding rod 913 is fixedly connected to a sleeve rod 916, and a guide shaft 917 is provided on the sleeve rod 916. The guide shaft 917 is inserted into the spiral groove provided on the horizontal support plate, and the flower shaft 99 moves synchronously with the correction bar 914. In this way, when the correction bar 914 is in the process, it can squeeze the tray 5 with the placement deviation so that the tray 5 can be corrected. In addition, during the movement, the slot opening 915 can make the sliding rod 913 move axially. Of course, there is a baffle on the sliding rod 913, so that the sliding rod 913 is always located in the slot opening 915. When the sliding rod 913 moves, the guide shaft 917 moves in the spiral groove. , the spiral groove and the guide shaft 917 can make the horizontal support plate rotate, so that the horizontal support plate can rotate 45 degrees. During the rotation process, the horizontal support plate can maintain a closer contact with the tray 5, and the tray 5 can be corrected in the length direction. The guide rail includes a plurality of connecting strips, and the connecting strip is located in the notch of the flower axis 99. One end of the connecting strip is fixedly connected to one side of the slider 94, and is connected in the notch of the flower axis 99 and can move axially, thus ensuring that the flower axis 99 and the connecting strip do not interfere with the axial movement. The curved guide strip 910 is fixedly connected to the plurality of connecting strips, and the curved guide strip 910 is provided with a displacement notch 911. The outer side of the correction strip 914 is fixedly connected with a second bevel gear 912, and the rotating rod 91 is provided with a first bevel gear 93. When the correction strip 914 moves, the second bevel gear 912 and the first bevel gear 93 can form a meshing state, and the gear 92 is meshing with the short rack 42;The horizontal support plate that originally rotated 45 degrees can continue to rotate until the horizontal support plate rotates to nearly 90 degrees, so that the base can support the stacked tray 5, and the horizontal support plates on both sides can be limited in the length direction. When the gear 92 is meshed and rotated with the short rack 42, when the rotating rod 91 rotates, the first bevel gear 93 drives the second bevel gear 912 to rotate, and then the correction bar 914 rotates on one side of the flower axis 99. Since the end of the sliding rod 913 is located on the curved guide bar 910, when the correction bar 914 rotates, the sliding rod 913 moves in the sliding groove mouth 915 and is guided downward by the curved guide bar 910. In this way, the height of the tray 5 is adjusted, so that the tray 5 moves downward by a certain distance, and the downward movement distance The advantage is that since the bottom tray 5 does not need to be adjusted, the upper tray 5 moves down as a whole to a closer distance, which can provide downward pressure when the side plate 10 falls, so that the side plate 10 can complete the collision with the lower tray 5 by its own weight. Of course, when the above scheme is implemented, the length of the slide slot 915 from top to bottom and the rotation range of the correction bar 914 are reduced successively, so that the distance of the upper downward movement can be increased, and then the difference in the downward pressure process can provide a gradually decreasing downward pressure, so that the hot air of the hot air blower 6 can be concentrated between the upper and lower trays 5 and the side plates 10, and flow in multiple groups of separate paths, so that the heat source is closer to the grass fruit, and the quality and efficiency of the whole drying are significantly improved. ;

[0056] It should be understood that a horizontal support plate is arranged between the front and rear correcting parts, and the horizontal support plate includes an adaptor sleeve 919, in which a spiral groove is arranged, and the surface of the adaptor sleeve 919 is fitted with one side of the splicing plate 918. The purpose of the surface of the adaptor sleeve 919 fitting with one side of the splicing plate 918 is to make them in a contact state when the pallet 5 is not placed, so as to prevent the two from detaching. A support frame 920 is arranged on one side of the adaptor sleeve 919, and a strip groove 921 is arranged on the support frame 920, and the strip groove 921 matches the edge shape of the pallet 5. The support frame 920 is overlapped with the L-shaped lap plate 58, and during the rotation of the support frame 920, the strip groove 921 always forms an abutment state with the L-shaped lap plate 58, so that the pallet 5 is placed to fall, thereby ensuring the stability of the switching process to the air duct.

[0057] The tray 5 needs to be described in detail. There are multiple trays 5, and the multiple trays 5 are placed on the support frames 9 on both sides at equal intervals from top to bottom. The tray 5 includes a U-shaped plate 51. Both sides of the U-shaped plate 51 are elastically rotatably provided with L-shaped lap plates 58. The L-shaped lap plates 58 are overlapped on the support frame 920. A baffle interlayer is provided on the U-shaped plate 51, and a locking component is provided in the baffle interlayer. When the locking component contacts the L-shaped lap plate 58, the horizontal tray can rotate 45 degrees and the side plate 10 falls to the lowest position, and the upper end of the locking component moves to the top of the U-shaped plate 51 in the baffle interlayer, and the locking component The movable end of the component passes through the hook groove 57 set on the U-shaped plate 51 and extends into the U-shaped plate 51. The locking assembly is set in the displacement groove reserved on the inner wall of the baffle interlayer. The displacement groove is provided with a slide bar 52. Two elastic clamping rods 55 are penetrated on the slide bar 52. The outer side of the elastic clamping rod 55 is provided with a guide inclined surface 56 at the top of the slide bar 52. The bottom of the two elastic clamping rods 55 is fixedly connected with a flexible shaft 53. The clamping shaft rod on the flexible shaft 53 passes through the hook groove 57. The flexible shaft 53 is elastically connected to the bottom of the slide bar 52 in the displacement groove. The clamping head of the elastic clamping rod 55 abuts against the limiting protrusion 104 in the locking cavity 102.

[0058] The U-shaped plate 51 is arranged in the width direction of the tray 5, and the L-shaped lap plates 58 are elastically arranged on both sides of the U-shaped plate 51, so that the U-shaped plate 51 is in a closed state, forming an independent space for placing the screen, and the screen provides a compression margin, so that when the L-shaped lap plates 58 on both sides rotate, it will not cause damage to the screen, and when the screen is deformed, the problem of grass fruit accumulation will not occur.

[0059] The locking assembly is arranged in the displacement groove. The function of the locking assembly is that when the elastic clamping rod 55 is pulled down to the lowest position, that is, when the clamping shaft rod on the flexible shaft 53 is located at the hook end of the hook groove 57, the two elastic clamping rods 55 are in a close state. At this time, the clamping head of the elastic clamping rod 55 and the limiting protrusion 104 in the locking cavity 102, and then the baffle 101 can be suspended in the baffle interlayer of the U-shaped plate 51;

[0060] When the top ends of the L-shaped lap plates 58 on both sides are subjected to extrusion force, the L-shaped lap plates 58 will move toward the position of the hook grooves 57, and the L-shaped lap plates 58 will cause the card shaft rod on the flexible shaft 53 to move to the lowest position when the hook end position of the hook groove 57 is located. During this process, the flexible shaft 53 causes the two upper elastic card rods 55 to move downward, and when the guide inclined surface 56 contacts the slide bar 52, the two elastic card rods 55 are in a state of being close to each other, and the card heads of the elastic card rods 55 are separated from the contact with the limiting protrusions 104 on both sides, and slide down from the baffle interlayer under the action of gravity of the baffle 101, and when the card shaft rod moves to the lowest position at the hook end position of the hook groove 57, it should be understood that the vertical groove of the hook groove 57 remains in contact with the L-shaped lap plate 58. The inclination of the connecting plate 58 when contacting the card shaft rod remains parallel, that is, the vertical slot is set at an angle, so under the elastic reset of the three reset springs 54, the slide bar 52 can be moved upward in the displacement groove, and the two elastic card rods 55 are also moved out of the slide bar 52, thereby ensuring that the card shaft rod is not blocked by the L-shaped lap plate 58 when it rises, thereby ensuring that the elastic card rod 55 can be quickly reset and moved to the top of the tray 5, and the side panel 10 is clamped in the baffle interlayer in the length direction of the tray 5, and the height of the side panel 10 is 1.2 to 1.4 times the spacing between the two adjacent trays 5 above and below, mainly to allow the bottom end of the side panel 10 to enter the baffle interlayer when the side panel 10 falls, forming a closed state. Of course, the side panel 10 includes a baffle 101, and a locking cavity 102 is provided at the locking assembly of the baffle 101, and a clamping groove 103 is provided below the locking cavity. The clamping groove 103 is located directly above the elastic clamping rod 55. During the falling process, the clamping groove 103 can be clamped with the two elastic clamping rods 55. Therefore, pressing down the tray 5 can also ensure stable and rapid alignment.

[0061] It should be noted that in the above embodiment, after the drying is completed, multiple U-shaped clamps can be used to clamp on two adjacent movable avoidance racks 4, so that multiple horizontally arranged display racks can be pulled out of the drying room 1 simultaneously. In this state, multiple trays 5 are stacked and supported by the base. In this way, the display rack after being pulled out can directly lift out multiple stacked trays 5 together, of course, depending on the operating habits of the operator.

[0062] When the drying process is specifically carried out, the switching operation can be performed during the process of fixing the green leaves. Of course, if the switching is not performed, the generated water vapor can be discharged from the gap between the trays 5, so that the speed of the internal air flow does not need to be increased, and the temperature can be controlled to be higher. If the switching is selected, an air duct can be formed. At this time, the air flow rate of the hot air blower 6 is increased and the temperature of the air flow is reduced. In this way, the fixing process can be carried out quickly, so that the air flow rate is increased, centralized processing can be carried out, and the drying efficiency is improved. The above operation can also be performed during the drying process. According to needs, drying can be carried out in a variety of ways;

[0063] Concentrate heat to ensure that the airflow flows quickly in the channel. The airflow can pass through the surface of the grass fruit to prevent over-drying and effectively utilize heat.

[0064] The uppermost tray 5 may be in an empty tray state, or a U-shaped baffle may be provided at the uppermost tray for restriction.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
