Description
Technical Field
[0001] This utility model relates to the field of fruit processing technology, and in particular to a continuous freeze-drying vacuum processing device for fruits. Background Technology
[0002] In the food processing industry, fruit freeze-drying technology is becoming increasingly important. Traditional fruit preservation methods easily lead to the loss of nutrients and a deterioration in taste. Continuous fruit freeze-drying vacuum processing equipment has emerged to address this issue, with the freeze-drying chamber being a key component. Early freeze-drying chambers were mostly intermittent, resulting in low production efficiency and difficulty in meeting the demands of large-scale markets. Continuous freeze-drying chambers can keep fruits in a vacuum low-temperature environment, completing the freeze-drying process uninterrupted, greatly improving production efficiency. However, they place extremely high demands on the equipment's sealing, temperature uniformity, and vacuum control, requiring continuous optimization of design and technology to maximize the preservation of fruit nutrients and flavor while achieving high-efficiency production.
[0003] In existing technologies, freeze-drying chambers typically include a drying chamber, a water-catching chamber, a heating system, and a vacuum system. Items to be freeze-dried are placed in the drying chamber, while the water-catching chamber contains a cooling hydrazine. The drying chamber and the water-catching chamber are separated by pipes and valves. The vacuum system evacuates the water-catching chamber, and the heating system heats the items. The water in the items sublimates and enters the water-catching chamber to be collected. This freeze-drying machine structure has the problem of items softening and deforming in the drying chamber, especially items with high water content that require a long freeze-drying time, affecting the appearance and quality of the freeze-dried product. Furthermore, the water-catching chamber has low water collection efficiency.
[0004] Existing patents offer solutions to the above problems, but freeze-drying processes have low continuity, resulting in low efficiency when large-scale processing is required. This is mainly due to the lengthy preparation process that requires continuous adjustments based on the size of the fruit and the spacing of the trays before processing, and the slow speed of storing freeze-dried fruit after processing, making it difficult to quickly deploy the equipment.
[0005] Therefore, a continuous freeze-drying vacuum processing device for fruits is proposed. Utility Model Content
[0006] The purpose of this invention is to provide a continuous freeze-drying fruit vacuum processing device that can solve the problems of long preparation time before processing and low storage efficiency after processing.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a continuous freeze-drying fruit vacuum processing device, including a freeze-drying chamber, a transmission rail movably connected to the inner side of the freeze-drying chamber, a sealing chamber door movably connected to the outer side of the freeze-drying chamber, a carrying mechanism movably connected to the inner side of the transmission rail, and an installation mechanism movably connected to the inner side of the carrying mechanism.
[0008] The supporting mechanism includes a sliding upright plate, a fixed plate, a supporting plate, an adjusting component, a composite plate, a first telescopic rod, and a compression spring. The sliding upright plate is movably connected to the inner side of the transmission rail. The fixed plate is fixedly connected to the top of the outer side of the sliding upright plate. The supporting plate is slidably connected to the outer side of the sliding upright plate. The adjusting component is movably connected to the outer sides of the fixed plate and the supporting plate. The composite plate is movably connected to the bottom of the bottom supporting plate and the outer side of the sliding upright plate. The first telescopic rod is fixedly connected to the inner side of the composite plate, and the compression spring is fixedly connected to the inner side of the first telescopic rod.
[0009] Preferably, the installation mechanism includes an installation groove, a sliding support crossbar, a second telescopic rod, a tension spring, a connecting clamp, an extension block, a limiting plate, and a limiting groove.
[0010] Preferably, the mounting groove is formed on the top of the support plate, the sliding support crossbar is fixedly connected to the top of the support plate, the second telescopic rod is fixedly connected to the outer side of the top of the sliding support crossbar, the tension spring is fixedly connected to the outer side of the second telescopic rod, the linkage clamp is fixedly connected to the outer side of the second telescopic rod, the linkage clamp is slidably connected to the outer side of the sliding support crossbar, and the linkage clamp is arranged on both sides of the mounting groove.
[0011] Preferably, the extension block is fixedly connected to the outside of the linkage clamp, the limiting plate is slidably connected to the inside of the extension block, the limiting slot is opened on the top of the bearing plate, and the limiting plate is movably connected to the inside of the limiting slot.
[0012] Preferably, the adjustment assembly includes a telescopic bracket, a support column, a linkage tab, and an electronic telescopic support column.
[0013] Preferably, the telescopic bracket is movably connected to the rear side of the fixed plate, the telescopic bracket is movably connected to the rear side of the bearing plate, the linkage pull piece is movably connected to the rear side of the bottom of the telescopic bracket, the linkage pull piece is slidably connected to the inner side of the support column, the support column is fixedly connected to the outer side of the sliding upright plate, the electronic telescopic support column is fixedly connected to the outer side of the support column, and the electronic telescopic support column is fixedly connected to the top of the linkage pull piece.

[0015] Preferably, the bottom of the freeze-drying chamber is fixedly connected to a support, and the top of the freeze-drying chamber is movably connected to an air vent.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. By setting up a carrying mechanism, this application can activate the electronic telescopic support column to drive a series of components through the pre-adjusted transfer structure. It can synchronously adjust the spacing of the carrying plates to adapt to fruits of different sizes. The reasonable adjustment of the spacing is conducive to water vapor diffusion and heat transfer, and can also improve the heat conduction utilization rate, ensuring continuous freeze-drying operation and improving the freeze-drying effect. At the same time, when the carrying plate is raised, the composite plate and internal structure can buffer the spacing adjustment to prevent the fruit from rolling off. This effectively solves the problems of low continuity of freeze-drying processing, low efficiency of large-scale processing and cumbersome pre-preparation caused by inconvenient spacing adjustment, and greatly improves production efficiency.
[0018] 2. This application improves the continuity and efficiency of freeze-drying processing by setting up an installation mechanism. By directly replacing the tray, the slow process of collecting fruit is avoided, saving time. Pulling the connecting clamp outward can accumulate elastic potential energy. The limiting plate and limiting slot are used to limit the connecting clamp, making it easy to remove the tray and freeze-dried fruit. Then, an empty tray is placed in, and the limiting plate is lifted to release the elastic potential energy and quickly fix the tray. This achieves rapid tray assembly and disassembly, which solves the problems of low continuity in freeze-drying processing, low efficiency in large-scale processing, and slow speed of collecting freeze-dried fruit after processing. This allows the equipment to be quickly put into a new round of operation, effectively improving the overall work efficiency. Attached Figure Description

[0026] 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.
[0027] Please see Figure 1-6 The present invention provides the following technical solution:
[0028] A continuous freeze-drying fruit vacuum processing device includes a freeze-drying chamber 1, a transfer rail 2 movably connected to the inner side of the freeze-drying chamber 1, a sealing chamber door 3 movably connected to the outer side of the freeze-drying chamber 1, a carrying mechanism 4 movably connected to the inner side of the transfer rail 2, and an installation mechanism 5 movably connected to the inner side of the carrying mechanism 4.
[0029] The supporting mechanism 4 includes a sliding upright plate 41, a fixed plate 42, a supporting plate 43, an adjusting component 44, a composite plate 45, a first telescopic rod 46, and a compression spring 47. The sliding upright plate 41 is movably connected to the inner side of the transmission rail 2. The fixed plate 42 is fixedly connected to the top of the outer side of the sliding upright plate 41. The supporting plate 43 is slidably connected to the outer side of the sliding upright plate 41. The adjusting component 44 is movably connected to the outer side of the fixed plate 42 and the supporting plate 43. The composite plate 45 is movably connected to the bottom of the bottom supporting plate 43 and the outer side of the sliding upright plate 41. The first telescopic rod 46 is fixedly connected to the inner side of the composite plate 45, and the compression spring 47 is fixedly connected to the inner side of the first telescopic rod 46.
[0030] In this embodiment, a transfer structure can be formed by sliding upright plate 41, fixed plate 42, bearing plate 43, composite plate 45 and tray 6. The transfer structure can be adjusted in the pre-preparation stage by adjusting component 44, which reduces manual time, increases pre-preparation efficiency and ensures continuity. The composite plate 45, first telescopic rod 46 and compression spring 47 can buffer the adjustment to prevent fruit inside tray 6 from rolling off, causing loss and equipment stagnation.
[0031] Specifically, such as Figure 2 , Figure 5 As shown, the installation mechanism 5 includes an installation groove 51, a sliding support crossbar 52, a second telescopic rod 53, a tension spring 54, a connecting clamp 55, an extension block 56, a limiting plate 57, and a limiting groove 58.
[0032] Specifically, such as Figure 2 , Figure 5 As shown, the mounting groove 51 is opened on the top of the bearing plate 43, the sliding support crossbar 52 is fixedly connected to the top of the bearing plate 43, the second telescopic rod 53 is fixedly connected to the outer side of the top of the sliding support crossbar 52, the tension spring 54 is fixedly connected to the outer side of the second telescopic rod 53, the linkage clamp 55 is fixedly connected to the outer side of the second telescopic rod 53, the linkage clamp 55 is slidably connected to the outer side of the sliding support crossbar 52, and the linkage clamp 55 is arranged on both sides of the mounting groove 51.
[0033] Specifically, such as Figure 2 , Figure 5 As shown, the extension block 56 is fixedly connected to the outside of the linkage clamp 55, the limiting plate 57 is slidably connected to the inside of the extension block 56, the limiting groove 58 is opened on the top of the bearing plate 43, and the limiting plate 57 is movably connected to the inside of the limiting groove 58.
[0034] In this embodiment: after freeze-drying, the fruit is placed into the storage point. To allow the transfer structure to quickly start a new round of operations, instead of slowly collecting the fruit from the tray 6, the tray 6 is directly replaced. The two sets of connecting clamps 55 on the inner side of the sliding support crossbar 52 are pulled outward. The connecting clamps 55 move outward, stretching the second telescopic rod 53 and the outer tension spring 54, accumulating elastic potential energy. When the connecting clamps 55 move to the position of the limiting slot 58, the limiting plate 57 slidably connected in the outer extension block 56 slides down due to gravity and gets into the limiting slot 58, thereby limiting the connecting clamps 55 on both sides. At this time, the tray 6 and freeze-dried fruit can be directly taken out. Then, the empty tray 6 is placed into the installation slot 51, and the limiting plates 57 on both sides are lifted to disengage them from the limiting position, releasing the elastic potential energy of the second telescopic rod 53 and the tension spring 54. The connecting clamps 55 on both sides will then move inward quickly, conveniently fixing the tray 6 and completing the quick assembly and disassembly.
[0035] Specifically, such as Figure 3 , Figure 4 , Figure 6 As shown, the adjustment assembly 44 includes a telescopic bracket 44a, a support column 44b, a linkage pull plate 44c, and an electronic telescopic support column 44d.
[0036] Specifically, such as Figure 3 , Figure 4 , Figure 6As shown, the telescopic bracket 44a is movably connected to the rear side of the fixed plate 42, the telescopic bracket 44a is movably connected to the rear side of the bearing plate 43, the linkage pull piece 44c is movably connected to the rear side of the bottom of the telescopic bracket 44a, the linkage pull piece 44c is slidably connected to the inner side of the support column 44b, the support column 44b is fixedly connected to the outer side of the sliding upright plate 41, the electronic telescopic support column 44d is fixedly connected to the outer side of the support column 44b, and the electronic telescopic support column 44d is fixedly connected to the top of the linkage pull piece 44c.
[0037] In this embodiment: by activating the electronic telescopic support column 44d, the linkage pull plate 44c is driven to rise and fall within the support column 44b, thereby driving the telescopic pull frame 44a to contract and extend. The bottom rotation node of the telescopic pull frame 44a is located behind the fixed plate 42, and other rotation nodes are distributed behind each bearing plate 43. The driving rotation node is located behind the bottom bearing plate 43. In this way, when the telescopic pull frame 44a moves, it can simultaneously drive all bearing plates 43 to move in tandem, adjusting the spacing synchronously to accommodate fruits of different volumes in the tray 6. Increasing the spacing facilitates moisture diffusion and uniform heat transfer; decreasing the spacing can improve heat conduction utilization, reduce heat loss, ensure continuous freeze-drying operation, and improve the freeze-drying effect.
[0038] Specifically, such as Figure 5 As shown, a tray 6 is movably connected to the inner side of the mounting slot 51.
[0039] Specifically, such as Figure 1 As shown, a support 7 is fixedly connected to the bottom of the freeze-drying chamber 1, and an air vent 8 is movably connected to the top of the freeze-drying chamber 1.
[0040] In this embodiment: the tray 6 can hold the fruit for freeze-drying, the bracket 7 can support the freeze-drying chamber 1, and the air vent 8 can balance the air pressure inside the chamber and adjust the vacuum level.
[0041] Working principle: In continuous fruit freeze-drying operations, the transfer structure is composed of a sliding upright plate 41, a fixed plate 42, a bearing plate 43, a composite plate 45, and a tray 6. Fruit is transferred via the transfer rail 2. After the fruit is guided to the freeze-drying chamber 1 for processing, the outer transfer rail changes course, allowing the internal transfer structure to directly guide the fruit to the receiving point. Changing course again allows for the receiving of the next batch of freeze-dried material, achieving continuous freeze-drying. Before freeze-drying operations, the transfer structure needs to be pre-adjusted to prevent interruptions. Activating the electronic telescopic support column 44d drives the linkage pull plate 44c to rise and fall within the support column 44b, thereby driving the telescopic pull frame. 44a contracts and stretches. The bottom rotating node of the telescopic bracket 44a is located behind the fixed plate 42, and the other rotating nodes are distributed behind each bearing plate 43. The driving rotating node is behind the bottom bearing plate 43. In this way, when the telescopic bracket 44a moves, it can simultaneously drive all the bearing plates 43 to move together and adjust the spacing synchronously to accommodate fruits of different sizes in the tray 6. Increasing the spacing is conducive to water vapor diffusion and uniform heat transfer; decreasing the spacing can improve the heat conduction utilization rate, reduce heat loss, ensure continuous freeze-drying operation, and improve the freeze-drying effect. When the bearing plate 43 is raised, the bottom bearing plate 43 pulls the top of the composite plate 45 in the same way. The composite plate 45 is composed of two plates. The top is slidably connected to the outer side of the sliding upright plate 41, and the bottom is fixed to the bottom of the sliding upright plate 41. When the bottom bearing plate 43 applies force to the top of the composite plate 45, the first telescopic rod 46 on the inner side of the composite plate 45 is stretched or compressed accordingly. The internal compression spring 47 accumulates elastic potential energy to buffer the speed and force of the spacing adjustment, preventing the fruit in the tray 6 from rolling off during the adjustment process and affecting the production progress. After freeze-drying is completed and the fruit enters the storage point, in order to enable the transfer structure to quickly start a new round of operations, the fruit is no longer slowly collected from the tray 6, but the tray 6 is directly replaced, and the inner side of the sliding support crossbar 52 is pulled outward. Two sets of interlocking clamps 55 move outward, stretching the second telescopic rod 53 and the outer tension spring 54, accumulating elastic potential energy. When the interlocking clamps 55 move to the position of the limiting slot 58, the limiting plate 57 slidably connected in the outer extension block 56 slides down due to gravity and gets into the limiting slot 58, limiting the interlocking clamps 55 on both sides. At this time, the tray 6 and freeze-dried fruit can be taken out directly. Then, the empty tray 6 is placed into the installation slot 51, and the limiting plates 57 on both sides are lifted to disengage them from the limiting position, releasing the elastic potential energy of the second telescopic rod 53 and the tension spring 54. The interlocking clamps 55 on both sides move inward quickly, conveniently fixing the tray 6 and completing the quick assembly and disassembly.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
