Description

Technical Field

[0001] This utility model relates to the field of vacuum precooling machine technology, and in particular to a vehicle-mounted dual-slot vacuum precooling machine for fruits and vegetables. Background Technology

[0002] A vacuum precooler is a cooling processing device that uses vacuum precooling technology to extract air and water vapor from a vacuum chamber using a vacuum pump, thereby reducing the air pressure inside the vacuum chamber. Under low pressure, the boiling point of water decreases, the latent heat of vaporization increases, and the free water on the surface of the object being cooled vaporizes, carrying away heat from itself and the environment, thus achieving a cooling effect.

[0003] A search revealed that Chinese Patent Publication No. CN110367331A discloses a vehicle-mounted dual-slot vacuum precooling machine for fruits and vegetables. The machine includes a mounting base, a support frame mounted on top of the mounting base, vacuum slots, vacuum slot doors mounted on the outside of the vacuum slot openings, and a refrigeration unit. Two sets of horizontally distributed vacuum slots are symmetrically fixedly connected to the top of the mounting base on both sides of the support frame. Each set of vacuum slots has a funnel-shaped storage hopper installed inside, and the bottom of the storage hopper has vertically distributed discharge ports. This invention, firstly, adopts a combined integrated structure. This structure allows for on-site storage and processing of fruits and vegetables after harvesting in the field, extending the shelf life of plastic-coated freshness and reducing quality degradation. Secondly, it includes an automated unloading mechanism, enabling automated unloading of fruits and vegetables, reducing operator workload and improving unloading efficiency.

[0004] A search revealed a utility model patent with Chinese patent publication number CN222257168U, which provides a digital vacuum precooling machine for fruits and vegetables, relating to the field of fruit and vegetable cooling technology. The machine includes a housing with a movably mounted sealing door on one side and casters fixedly mounted on the bottom. Slide rails are fixedly connected to both sides of the inner wall of the housing. The interior of the housing has a holding plate, with a first baffle and a second baffle movably mounted on the top of the holding plate. A fixed cylinder is fixedly connected to the bottom of the housing. The first and second baffles on the top of the holding plate limit the movement of fruits and vegetables. When storing a small amount of fruits and vegetables, the position of the first and second baffles can be adjusted by rotating a first handle to prevent the fruits and vegetables from rolling on the top of the holding plate. The casters at the bottom of the housing allow for movement and transportation. Rotating a second handle adjusts the height of the support plate, ensuring it contacts the ground and preventing the housing from shaking when the position is fixed.

[0005] However, in existing technologies, water vapor emitted by fruits and vegetables after vacuuming tends to adhere to the inner wall of the vacuum chamber, thereby reducing the cooling effect of the vacuum chamber. Poor cooling of fruits and vegetables can easily lead to spoilage.

[0006] To address these issues, we propose a vehicle-mounted dual-slot vacuum precooling machine for fruits and vegetables. Utility Model Content

[0007] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a vehicle-mounted dual-slot vacuum precooling machine for fruits and vegetables.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A vehicle-mounted dual-slot vacuum precooling machine for fruits and vegetables includes a precooling unit and further includes:

[0010] Vacuum chambers are respectively located on both sides of the precooling machine. A valve is provided between the precooling machine and the vacuum chambers. One side of the valve is fixedly connected to the vacuum chamber, and the side of the valve opposite to the vacuum chamber is fixedly connected to the precooling machine.

[0011] The first suction plate is fixed to the bottom and top inner walls of the vacuum chamber. The first suction plate is provided with a plurality of first suction holes. The end face of the first suction plate facing the interior space of the vacuum chamber has a convex wave shape.

[0012] The second suction plate is fixed to the inner walls of both sides of the vacuum chamber. The second suction plate is provided with multiple second suction holes. The end face of the second suction plate facing the interior space of the vacuum chamber is concave and wavy.

[0013] More preferably, the vacuum chamber is provided with a door on the side opposite to the precooler, and the door is provided with a control panel with multiple control buttons.

[0014] In a further preferred embodiment, an observation window is provided in the middle of one side of the box door, and a sliding window is provided on the outer side of the observation window, with a handle on one side of the sliding window.

[0015] More preferably, the precooler is provided with multiple protruding circulation pipes, the circulation pipes are spaced evenly, and the bottom of both ends of the precooler is provided with support seats located between the circulation pipes.

[0016] More preferably, the support base is L-shaped, one end of the support base is fixed to the precooling machine by welding, and the bottom end of the support base is fixedly connected to the external vehicle by screws.

[0017] More preferably, one end of the valve is provided with a first side tube, which penetrates the interior of the vacuum chamber and is connected to the second suction plate.

[0018] More preferably, the valve has a second side pipe at one end opposite to the first side pipe, the second side pipe penetrates the interior of the vacuum chamber, and the second side pipe is connected to a second suction plate on the opposite side of the second suction plate connected to the first side pipe inside the vacuum chamber.

[0019] More preferably, the valve has a first bottom edge tube at its bottom end, the first bottom edge tube penetrates the vacuum chamber, and the first bottom edge tube is connected to a first air extraction plate at the bottom of the vacuum chamber.

[0020] More preferably, the valve has a first top edge tube at its top, which penetrates the vacuum chamber and is connected to a first suction plate at the top of the vacuum chamber.

[0021] More preferably, the first suction plate is internally connected, the second suction plate is internally connected, and the top and bottom ends of the second suction plate are in contact with the first suction plate.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] By setting up a first and second wavy suction plate, water vapor can leave its own first or second suction hole through the protrusions and depressions. After vacuuming, the water vapor discharged from the vegetables is less likely to adhere to the inner wall of the vacuum chamber, thus improving the cooling effect of the vacuum chamber. Good cooling effect of fruits and vegetables reduces the risk of spoilage. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] refer to Figure 1 A vehicle-mounted dual-slot vacuum precooling machine for fruits and vegetables 1 includes a precooling machine 1, which is a cooling processing device that uses vacuum precooling technology to extract air and water vapor from a vacuum chamber 2 to reduce the air pressure inside the vacuum chamber 2. Under low air pressure, the boiling point of water decreases and the latent heat of vaporization increases. Free water on the surface of the object being cooled undergoes vaporization, carrying away its own and the environment's heat, thus achieving a cooling effect. Referring to the invention with Chinese Patent Publication No. CN110367331A, the precooling machine 1 is prior art and will not be described in detail again.

[0031] refer to Figure 1 and Figure 4 The vacuum box 2 is used to place fruits and vegetables for cooling. The vacuum boxes 2 are respectively located on both sides of the precooling machine 1. The two vacuum boxes can hold more fruits and vegetables, increasing the single transport capacity of the vehicle. A valve 14 is provided between the precooling machine 1 and the vacuum box 2. One side of the valve 14 is fixedly connected to the vacuum box 2, and the side of the valve 14 opposite to the vacuum box 2 is fixedly connected to the precooling machine 1. Vacuuming is controlled through the valve 14 to control the vacuuming of each pipeline.

[0032] refer to Figure 3 The first suction plate 8 can evacuate the vacuum chamber 2 from the bottom and top. The first suction plate 8 is fixed to the bottom and top inner walls of the vacuum chamber 2. The first suction plate 8 is provided with multiple first suction holes 9. Gas and water vapor can be extracted through the first suction holes 9. The end face of the first suction plate 8 facing the interior space of the vacuum chamber 2 has a convex wave shape, which facilitates the flow of attached water vapor.

[0033] refer to Figure 3 The second suction plate 10 can evacuate from both sides of the vacuum chamber 2. The second suction plate 10 is fixed to the inner walls of both sides of the vacuum chamber 2. The second suction plate 10 is provided with multiple second suction holes 11. Gas and water vapor can be extracted through the second suction holes 11. The end face of the second suction plate 10 facing the interior space of the vacuum chamber 2 is concave and wavy. The wavy shape facilitates the flow of attached water vapor.

[0034] refer to Figure 3 By setting the first suction plate 8 and the second suction plate 10 in a wave shape, water vapor can leave the first suction hole 9 or the second suction hole 11 through the protrusions and depressions. After vacuuming, the water vapor discharged from the vegetables is less likely to adhere to the inner wall of the vacuum chamber 2, thereby improving the cooling effect of the vacuum chamber 2. Good cooling effect of fruits and vegetables makes them less likely to rot.

[0035] refer to Figure 2 The vacuum chamber 2 is equipped with a door 3 on the side opposite to the precooler 1. By opening the door 3, fruits and vegetables can be placed into the vacuum chamber 2 for vacuum precooling. The door 3 is equipped with a control panel 7, which has multiple control buttons. The control buttons can be used to control the vacuum chamber 2 to perform vacuuming, and the cooling temperature and time can be controlled.

[0036] refer to Figure 2 An observation window 4 is provided in the middle of one side of the door 3. A sliding window 5 is provided on the outside of the observation window. A handle 6 is provided on one side of the sliding window 5. A control panel 7 is provided on one side of the observation window. The sliding window 5 can be opened by pulling the handle 6. The user can observe the cooling status inside the vacuum chamber 2 through the observation window 4. The observation window 4 is sealed and has transparent glass.

[0037] refer to Figure 4 The precooler 1 is equipped with multiple protruding circulation pipes 12, through which water vapor and air can be extracted and circulated. The precooler 1 also has exhaust ports for discharging gas from the circulation pipes 12. The spacing between the circulation pipes 12 is uniform, ensuring consistent air pressure within the pipes and extending their service life. Support seats 13 are located at both ends of the precooler 1, between the circulation pipes 12. The support seats 13 provide support for the precooler 1.

[0038] refer to Figure 4 The support base 13 is L-shaped, which has good stability. One end of the support base 13 is fixed to the precooler 1 by welding. Welding can stably connect the support base 13 and the precooler 1. The bottom end of the support base 13 is fixed to the external vehicle by screws. The precooler 1 can be disassembled by removing the screws, which is convenient.

[0039] refer to Figure 4 One end of valve 14 is provided with a first side pipe 15, which penetrates the interior of vacuum chamber 2 and is connected to the second suction plate 10. By connecting the first side pipe 15 to the second suction plate 10, the precooler 1 can perform suction on one side of the vacuum chamber 2.

[0040] refer to Figure 4 A second side pipe 17 is provided at one end of the valve 14 opposite to the first side pipe 15. The second side pipe 17 penetrates the interior of the vacuum chamber 2. The second side pipe 17 is connected to the second suction plate 10 on the opposite side of the second suction plate 10 connected to the first side pipe 15 inside the vacuum chamber 2. Through the second suction plate 10 at the other end of the second side pipe 17, the precooler 1 can evacuate the two ends inside the vacuum chamber 2 through the first side pipe 15 and the second side pipe 17, covering a large area.

[0041] refer to Figure 4 The bottom end of the valve 14 is provided with a first bottom edge pipe 16, which penetrates the vacuum box 2 and is connected to the first suction plate 8 at the bottom of the vacuum box 2. Thus, the precooler 1 can evacuate the bottom of the vacuum box 2 through the first bottom edge pipe 16 and the first suction plate 8.

[0042] refer to Figure 4 The valve 14 is provided with a first top edge pipe 18, which penetrates the vacuum box 2 and is connected to the first suction plate 8 at the top of the vacuum box 2. Thus, the precooler 1 can evacuate the bottom of the vacuum box 2 through the first bottom edge pipe 16 and the first top edge pipe 18, covering a large area.

[0043] refer to Figure 3 The first suction plate 8 is connected to the inside of the vacuum chamber 2, and the second suction plate 10 is connected to the inside of the vacuum chamber 2. This allows vacuuming to be performed from various positions inside the vacuum chamber 2 through the first suction port 9 and the second suction port 11. The top and bottom of the second suction plate 10 are in contact with the first suction plate 8, so that water vapor will adhere to the inner wall of the vacuum chamber 2 and can only adhere to the first suction plate 8 and the second suction plate 10.
