Description

Technical Field

[0001] The utility model relates to a dried fruit drying device, and more particularly to a dried fruit drying room which can effectively improve the drying effect of the drying room so that all the dried fruits can be heated evenly, and which is easy to manufacture, has reasonable cost and has good drying effect. Background Art

[0002] The traditional method of drying preserved fruits is natural drying, which is greatly restricted by weather conditions, takes a long time to dry, has low efficiency, is easily contaminated by dust and insects, and is difficult to ensure the sanitary quality of the preserved fruits. Natural drying is difficult to achieve uniform drying, and the quality of the preserved fruits varies greatly, with large differences in color and taste.

[0003] To this end, people use universal drying rooms to complete the drying process of preserved fruits. However, existing drying rooms are prone to uneven heating of the preserved fruits due to hot air flow, resulting in the preserved fruits in some areas being over-dried while the preserved fruits in other areas are not dried sufficiently. The preserved fruits in over-dried areas may become hard and have a worse taste, while the preserved fruits in insufficiently dried areas may become moldy, which not only affects the taste and quality of the preserved fruits and affects the safety of the products, but also causes energy waste.

[0004] In order to solve the above problems, a Chinese patent document with publication number CN 220169902 U and titled "A Curing Barn with Stable Hot Air Circulation" discloses a curing barn, which includes a curing barn body, side air ducts on both sides of the curing barn body, and fixed air nests on both sides of the top of the curing barn body. The interiors of the two air nests are respectively connected to the air ducts on both sides. Several air ducts are also connected between the two air nests, and a two-way fan is fixed in each air duct.

[0005] However, the applicant found that although the drying room has achieved a certain degree of improvement in the hot air distribution and made the preserved fruits heated more evenly by improving the flow direction of the hot air in the drying room, it still cannot effectively eliminate the defect of uneven heating of different areas of the preserved fruits due to the conflict between the structure of the preserved fruit drying equipment and the hot air flow. The problem of uneven heating of preserved fruits in different areas and resulting in unstable quality still exists. Moreover, since this technology requires substantial improvements to the structure of ordinary drying rooms, the cost of the drying room is too high, resulting in a low cost-effectiveness of this technology, which is difficult to meet the needs of producers. Utility Model Content

[0006] The purpose of this utility model is to provide a preserved fruit drying room with good drying effect, which can effectively improve the drying effect of the drying room, so that all preserved fruits can be heated evenly, and is easy to manufacture and has reasonable cost. The technical solution adopted is as follows:

[0007] 18. The fruit drying room as claimed in claim 17, wherein the baking room comprises a baking room body, at least one baking lamp, at least one three-hole bellows and at least one baking rack. The inner cavity of the baking room body comprises an inner bottom surface, and the baking lamp and the three-hole bellows are respectively installed in the inner cavity of the baking room body, and the characteristic is that the said fruit drying room further comprises at least one rotatable supporting device, the rotatable supporting devices and the baking racks are the same in number and correspond one to one, the rotatable supporting device is installed on the inner bottom surface of the inner cavity of the baking room body, and each baking rack is respectively arranged on the corresponding rotatable supporting device; the rotatable supporting device comprises a support platform, a rotatable disk, a servo motor and at least one cylinder, all cylinders are fixed on the inner bottom surface of the inner cavity of the baking room body and the piston shaft of the cylinder extends vertically upward and is connected to the support platform, the servo motor is fixed on the bottom surface of the support platform and the output shaft of the servo motor extends upward through the support platform, the rotatable disk is fixed on the output shaft of the servo motor and the rotatable disk is located on the top surface of the support platform, and each baking rack is respectively arranged directly above the rotatable disk of the corresponding rotatable supporting device. When the baking rack needs to be rotated, all the cylinders of the rotatable support device operate, and the piston shafts of the cylinders extend upward, driving the support platform and the rotatable plate to rise until the rotatable plate contacts the bottom surface of the baking rack, lifting the baking rack and placing it in a suspended state. Then the servo motor operates, driving the rotatable plate to rotate a certain angle and then stop. Finally, the piston shafts of the cylinders retract downward, driving the support platform and the rotatable plate to descend until the rotatable plate is away from the bottom surface of the baking rack, and the baking rack returns to a state of contact with the inner bottom surface of the baking room body. In this way, rotating the baking rack at an angle at regular intervals can effectively ensure that the hot air flows evenly throughout the space, blowing the preserved fruits without blind spots, and all receiving hot air of the same intensity and temperature, thereby achieving uniform drying and avoiding local over-drying or insufficient drying.

[0008] In a more preferred solution, the baking lamps are fixed above the inner cavity of the baking room body and arranged in a linear array; the three-hole bellows are fixed on the side wall of the inner cavity of the baking room body and are arranged in a ring shape.

[0009] A better solution is that a cross fixing frame is provided inside the three-hole bellows, a driving motor is provided on the side wall of the cross fixing frame, a fan is installed on the output shaft of the driving motor, and air guide plates are respectively provided at the four corners of the bottom surface of the inner cavity of the baking room body, and the air guide plates are installed on the bottom surface of the inner cavity of the baking room body using fixing rods.

[0010] A preferred solution is that a plurality of baking tables are installed in the middle of the baking rack, and the baking tables are arranged in a linear array from top to bottom in the middle of the baking rack. A plurality of support blocks are installed at the bottom of the baking rack, and these support blocks are arranged around the bottom of the baking rack. A support rod is fixed to the bottom of the support block, and a roller is installed at the bottom of the support rod.

[0011] Compared with the prior art, the beneficial effect of the present invention is that, due to the provision of a rotatable supporting device, the baking rack is lifted to a suspended state and rotated to an angle and then lowered at regular intervals during the baking process, so that the preserved fruits placed thereon can continuously change their orientation, so that the preserved fruits in each area have the opportunity to be exposed to hot air from different directions, thereby effectively avoiding the conflict between the baking rack structure and the hot air, which causes the preserved fruits in different areas to be heated unevenly, resulting in some preserved fruits being over-dried and / or some preserved fruits being insufficiently dried.

A cross-shaped fixing frame 301 is installed inside each of the three-hole bellows 3. A drive motor (not visible in the figure) is mounted on the sidewall of the cross-shaped fixing frame 301. A fan 302 is mounted on the output shaft of the drive motor. Air deflectors 4 are installed at the four corners of the inner bottom surface of the barn body 1. The air deflectors 4 are mounted to the inner bottom surface of the barn body 1 using fixing rods 5. A mounting seat 6 is provided on one side of the outer wall of the barn body 1 at the outlet. A convex sealing door 7 for sealing the outlet of the barn body 1 is rotatably mounted on the mounting seat 6. A handle 701 is mounted on the outer wall of the convex sealing door 7. A positioning seat 8 is installed on the other side of the exit of the outer side wall of the baking room body 1. The positioning seat 8 is arranged near the side of the hand handle 701. A rotating buckle 9 is installed at the end of the positioning seat 8. A limiting buckle 10 that can cooperate with the rotating buckle 9 is installed on the side wall of the convex sealing door 7. When the convex sealing door 7 is closed, the rotating buckle 9 and the limiting buckle 10 can be connected to each other in a buckled and locked manner.

[0016] like Figure 1 、 2As shown, the preserved fruit baking room also includes a plurality of baking racks 11. The inner cavity of the baking room body 1 has an inner bottom surface. A plurality of rotatable support devices 12 are installed on the inner bottom surface of the inner cavity of the baking room body 1. The number of rotatable support devices 12 and the baking racks 11 are the same and correspond one to one. Each baking rack 11 is respectively arranged on the corresponding rotatable support device 12.

[0017] like Figure 2 、 3 As shown, the rotatable support device 12 includes a support platform 1201, a rotatable disk 1204, a servo motor 1203, and four cylinders 1202. All cylinders 1202 are fixed on the inner bottom surface and the piston shafts of the cylinders 1202 extend vertically upward and are connected to the support platform 1201. The servo motor 1203 is fixed on the bottom surface of the support platform 1201 and the output shaft of the servo motor 1203 extends upward through the support platform 1201. The rotatable disk 1204 is fixed on the output shaft of the servo motor 1203 and the rotatable disk 1204 is located on the top surface of the support platform 1201. Each baking rack 11 is respectively arranged directly above the rotatable disk 1204 of the corresponding rotatable support device 12.

[0018] like Figure 1 、 2 As shown, an optional embodiment of the present application, a plurality of baking tables 1101 are installed in the middle of the baking rack 11; all baking tables 1101 are arranged in a linear array from top to bottom in the middle of the baking rack 11; a plurality of support blocks 1102 are installed at the bottom of the baking rack 11, and these support blocks 1102 are arranged around the bottom of the baking rack 11, and a support rod 1103 is fixed to the bottom of the support block 1102, and a roller 1104 is installed at the bottom of the support rod 1103.

[0019] like Figure 1 As shown, a drainage hole 15 is provided on the inner cavity side wall of the baking room body 1, and a water seal cover 16 is provided at the end of the drainage hole 15. During operation, when water accumulates in the inner cavity of the baking room body 1, the water seal cover 16 provided at the end of the drainage hole 15 is removed, and the water inside the baking room body 1 can flow out through the drainage hole 15 provided on the inner cavity side wall of the baking room body 1. The presence of accumulated water will increase the humidity in the baking room and affect the drying speed and quality of the preserved fruits. The above structure can effectively drain the accumulated water in time to avoid the accumulated water affecting the drying effect of the preserved fruits, and can also make cleaning and maintenance more convenient. The water seal cover 16 is installed above the drainage hole 15 to form a water seal to prevent the odor in the drainage pipe from flowing back into the baking room.

[0020] During operation, when it is time to bake preserved fruit, a large amount of preserved fruit is first spread out on the baking table 1101 (a preserved fruit collection basket can be used to store the spread preserved fruit, which is then placed on the baking table 1101). The baking rack 11 is then pushed into the baking room body 1 using the rollers 1104 at its bottom. The convex sealing door 7 is then closed by gripping the handle 701. The convex sealing door 7 is locked by rotating the buckle 9 to tightly engage the limit buckle 10 fixed to the side wall of the convex sealing door 7. The heat generated by the baking lamp 2 installed on the top of the baking room body 1 is then driven by the drive motor of the multiple three-hole bellows 3 to rotate the fan 302. As the fan 302 rotates, the air guide plate 4 inside the baking room body 1 circulates and bakes evenly within the baking room body 1.

[0021] Every period of time (a period of time is 2 hours in this embodiment), the four cylinders 1202 of each rotatable support device 12 synchronously extend the piston shaft upward to lift the support platform 1201 upward until the rotatable disk 1204 is against the baking rack 11 located above and lifts the baking rack 11 to a suspended state, and then the servo motor 1203 drives the rotatable disk 1204 to rotate an angle (the angle is 60 degrees in this embodiment), and the baking rack 11 follows the rotatable disk 1204 to rotate the angle, and finally the four cylinders 1202 synchronously retract the piston shaft until all the rollers 1104 of the baking rack 11 return to the bottom surface. This design allows all preserved fruits to better contact with hot air.

[0022] When water accumulates inside the baking room body 1, the water sealing cover 16 provided at the end of the drainage hole 15 can be removed, and the water inside the baking room body 1 can flow out through the drainage hole 15 opened on one side wall of the baking room body 1.
