Description

TECHNICAL FIELD

[0001] The utility model relates to the field of vacuum cooling machinery, especially relates to a horizontal vacuum pre-cooler and a halogen cooking production line using the vacuum pre-cooler. BACKGROUND

[0002] The vacuum pre-cooler is used for rapidly cooling the high-temperature food prepared in the food production process, so as to facilitate the packaging and storage in the later period. Compared with the traditional cooling method, the vacuum pre-cooling technology has the characteristics of fast cooling speed, uniform cooling temperature, avoidance of secondary pollution of the environment to food, improvement of the quality of cooked food products, less energy consumption, and convenient transportation. Based on the above advantages, the vacuum pre-cooler is widely used in the field of prepared food preparation.

[0003] An existing vacuum pre-cooler is a vertical single-side door structure. When pre-cooling the high-temperature food prepared, the food needs to be sent into the pre-cooling cabinet of the vacuum pre-cooler from the vertical door by using a trolley or manual carrying, and then the vertical door is closed for pre-cooling. After the pre-cooling is completed, the vertical door is opened again, and the food is carried out by using the trolley or manual carrying. Taking halogen cooking as an example, after the food material completes the halogen cooking process in the halogen cooking pot, the food material needs to be taken out from the halogen cooking pot by using a mechanical device and sent into the trolley. The trolley is used to send the halogen-cooked food into the vacuum pre-cooler for cooling. After the cooling is completed, the food is carried out by using the trolley or manual carrying, and then a subsequent packaging process is performed. The food needs to go through a transfer process from the halogen cooking pot to the vacuum pre-cooler. During the transfer process, the risk of pollution is increased, and it is time-consuming and labor-intensive.

[0004] Another existing vacuum pre-cooler is a vertical double-side door structure. The pre-cooling cabinet of the vacuum pre-cooler is provided with an inlet door and an outlet door arranged oppositely. The pre-cooling cabinet of the vacuum pre-cooler is generally embedded in a wall, and the wall is used to separate the heating process from the packaging process after pre-cooling. When pre-cooling the high-temperature food prepared, the food needs to be sent into the pre-cooling cabinet of the vacuum pre-cooler from the inlet door by using a trolley or manual carrying. The inlet door and the outlet door are closed simultaneously for pre-cooling. After the pre-cooling is completed, the outlet door is opened again, and the food is carried out by using the trolley or manual carrying for the next process. This kind of vacuum pre-cooler also needs to use the trolley or manual carrying for transfer, which is time-consuming and labor-intensive.

[0005] For a large food processing production line, multiple cooking pots are arranged. After the food material is placed in a cooking basket, the cooking basket is placed into a cooking pot from the top opening of the cooking pot. After the cooking process is completed, the cooking basket with the food material is taken out from the top opening of the cooking pot and moved to a trolley on one side of the cooking pot, and then transported to the vacuum pre-cooler for cooling. This transfer process consumes a lot of manpower and slows down the production speed, thereby reducing the production efficiency. Utility model content

[0052] As Figure 9 shown in the figure, a horizontal vacuum pre-cooling machine comprises a pre-cooling cabinet, the pre-cooling cabinet is connected with a vacuumizing device and a re-pressurizing device, the pre-cooling cabinet comprises a cabinet body 11 with an open top end, the open end of the cabinet body 11 is provided with a cabinet door 12 which is opened by translating to one side, the two sides of the translation stroke of the cabinet door 12 are provided with cabinet door 12 supporting devices, and the cabinet door 12 is connected with a translation driving device.

[0053] Different from the structure of the conventional pre-cooling cabinet with a side opening door, the pre-cooling cabinet in the present application has an open top end of the cabinet body 11 and is provided with the cabinet door 12, when the pre-cooling cabinet is needed to place the goods to be cooled, the cabinet door 12 is driven by the translation driving device to translate to one side, the open top end of the cabinet body 11 is opened, and the goods to be cooled are put into the cabinet body 11 from the open top end. The top feeding mode enables the vacuum pre-cooling machine to match many top feeding and discharging devices, such as halogen boiling devices. As both are top feeding and discharging, the process of transferring and loading and unloading the goods can be reduced, not only the working procedure and manpower can be saved, but also the working efficiency can be improved, and the risk of food pollution can be reduced.

[0054] Further, the cabinet body 11 is further provided with a steam exhaust port, the steam exhaust port is provided with a steam exhaust pipe 21, the open end of the steam exhaust pipe 21 is provided with a filter screen 22, and the steam exhaust pipe 21 is provided with a solenoid valve 23.

[0055] Further, the horizontal vacuum pre-cooling machine further comprises a frame body 3, and the pre-cooling cabinet is installed on the frame body 3. By arranging the frame body 3, the pre-cooling cabinet can be arranged at a suitable height, facilitating matching with other matched equipment. The frame body 3 adopts a frame structure, and the pre-cooling cabinet, the vacuumizing device and the pressure restoring device are installed on the frame body 3. The frame body 3 is provided with a guard plate for packaging the vacuumizing device and the pressure restoring device. The vacuumizing device and the pressure restoring device can be completely packaged, or only part of the structure can be packaged according to the requirement.

[0056] Further, the cabinet door 12 supporting device comprises guide rails arranged on both sides of the translational stroke of the cabinet door 12, and the two sides of the cabinet door 12 are provided with sliding devices matched with the guide rails. The cabinet door 12 can slide back and forth in the translational stroke by means of the sliding devices matched with the guide rails, so as to realize the opening and closing of the cabinet door 12.

[0057] Further, the guide rails comprise fixed guide rails 41 and lifting guide rails 42, and the lifting guide rails 42 are arranged on both sides of the opening end of the cabinet body 11. Each of the lifting guide rails 42 is connected with a jacking device for jacking the lifting guide rail 42 to be flush with the fixed guide rail 41. The lifting guide rails 42 and the cabinet body 11 are provided with lifting guide devices. The guide rails are installed on the frame body 3. The fixed guide rails 41 are fixedly connected with the frame body 3, and the lifting guide rails 42 are movably connected with the frame body 3. The lifting guide rails 42 have the freedom of rising and falling on the frame body 3. When the cabinet door 12 runs onto the lifting guide rails 42, the cabinet door 12 is located above the opening end of the pre-cooling cabinet. At this time, there is still a gap between the cabinet door 12 and the opening end of the pre-cooling cabinet. The lifting guide rails 42 slide downward along the lifting guide devices, and the cabinet door 12 falls onto the cabinet body 11 to block the opening end. The design of the lifting guide rails 42 enables the cabinet door 12 to block the opening end of the cabinet body 11 by its own gravity without the need of adding external force. When pre-cooling is performed, the pre-cooling cabinet is vacuumized, and the pre-cooling cabinet is in a negative pressure state. At this time, the cabinet door 12 is sucked by the inside of the pre-cooling cabinet, so that the cabinet door 12 further falls down to more tightly block the opening end of the pre-cooling cabinet. In the case that the cabinet door 12 falls down, the lifting guide rails 42 can automatically cooperate with the falling down, so as to prevent the cabinet door 2 from further falling down to rigidly extrude the guide rails and other components, and prevent the damage of the components. The jacking device cooperates with the action.

[0058] Further, the jacking device comprises a toggle arm 43 rotatably installed on the outer wall of the cabinet body 11, the toggle arm 43 is rotatably connected with the cabinet body 11 at the corner of the toggle arm 43, one end of the toggle arm 43 is drivingly connected with the lifting guide rail 42, and the other end of the toggle arm 43 is drivingly connected with a lifting driving device. The lifting and lowering of the lifting guide rail 42 is controlled by the swing of the toggle arm 43. When the lifting guide rail 42 is lifted, the lifting guide rail 42 is flush with the fixed guide rail 41, the cabinet door 12 is slid from the fixed guide rail 41 to the lifting guide rail 42, at this time, the cabinet door 12 is above the opening end of the cabinet body 11, and a gap is left between the cabinet door 12 and the opening end of the cabinet body 11, then the lifting guide rail 42 is lowered, and the cabinet door 12 falls to the opening end of the cabinet body 11 to close the opening end of the cabinet body 11. The design of the toggle arm 43 can flexibly drive the lifting and lowering of the lifting guide rail 42, thereby controlling the closing and opening of the cabinet door 12 and the opening end of the cabinet body 11.

[0059] Further, the lifting driving device comprises a telescopic rod 441, the telescopic rod is drivingly connected with a driving motor 442, and the power output end of the telescopic rod 441 is hingedly connected with the toggle arm.

[0060] Alternatively, the lifting driving device comprises an electric push rod, and the power output end of the electric push rod is hingedly connected with the toggle arm 43. The telescopic rod 441 or the electric push rod drives the toggle arm 43 to swing, when the telescopic rod 441 or the electric push rod is elongated, the toggle arm 43 swings and pushes the lifting guide rail 42 to lift, when the telescopic rod 441 or the electric push rod is retracted, the toggle arm 43 swings and contacts the jacking force of the lifting guide rail 42, and the lifting guide rail 42 is lowered under the action of its own gravity.

[0061] Further, the end of the toggle arm 43 connected with the lifting guide rail 42 is rotatably installed with a top wheel 45, and the top wheel 45 is abuttingly connected with the lifting guide rail 42. The top wheel 45 is rotatably installed on the toggle arm 43, and the top wheel 45 rotates in the process of jacking the lifting guide rail 42, which can reduce friction and make the jacking action smoother.

[0062] Further, the end of the toggle arm 43 connected with the lifting guide rail 42 is arc-shaped, and the arc-shaped end of the toggle arm 43 is abuttingly connected with the lifting guide rail 42. The position of the toggle arm 43 in contact with the lifting guide rail 42 is arc-shaped, which can ensure that the toggle arm 43 smoothly and stably jacks up the lifting guide rail 42. During the jacking operation, the arc-shaped end of the toggle arm 43 moves axially along the lifting guide rail 42. Compared with the structure of the top wheel 45 described above, the friction between the jacking surfaces will be larger. In order to improve the problem of large friction, a roller can be installed on the arc-shaped end of the toggle arm 43, the number of the roller can be determined as appropriate, and the roller has the same effect as the top wheel 45 described above, which will not be described here.

[0063] Further, the cabinet body 11 is fixedly provided with a crank arm seat 46, and the crank arm 43 is hingedly connected to the crank arm seat 46. The crank arm 43 is preferably L-shaped. The crank arm 43 can swing around the hinge point of the crank arm 43 and the crank arm seat 46, and convert the extension and retraction movement of the telescopic rod 441 or the electric push rod into the lifting movement of the lifting guide rail 42; the design of the crank arm seat 46 can facilitate the installation of the crank arm 43.

[0064] Further, the bottom of the lifting guide rail 42 is provided with a jacking block 47, and one end of the crank arm 43 is drivingly connected to the jacking block 47. The jacking block 47 is designed to move the contact point between the crank arm 43 and the lifting guide rail 42 downward, thus leaving space for the installation of the lifting guide device and preventing the telescopic rod 441 or the electric push rod from interfering with the lifting guide device.

[0065] Further, the lifting guide device includes guide assemblies installed on both sides of the jacking device, and each guide assembly includes a guide seat 48 fixedly installed on the cabinet body 11 and a guide sleeve 49 fixedly installed on the lifting guide rail 42 and slidingly matched with the guide seat 48. The lifting guide rail 42 and the guide sleeve 49 are connected by an L-shaped metal piece, which includes two vertically arranged and integrally formed connecting plates, one of which is fixedly connected to the bottom of the lifting guide rail 42, and the other of which is fixedly connected to the guide sleeve 49. During the lifting of the lifting guide rail 42, the guide sleeve 49 fixedly connected to the lifting guide rail 42 moves along the guide seat 48, thus ensuring that the lifting guide rail 42 will not deviate during the lifting and ensuring that the lifting guide rail 42 can be accurately connected to the fixed guide rail 41 after being lifted.

[0066] Further, the guide rail is a sliding rail (not shown in the figure), and the sliding device includes a sliding block fixedly connected to the cabinet door 12 and slidingly connected to the sliding rail. The cabinet door 12 moves on the sliding rail by means of the sliding block, thus realizing the opening and closing of the cabinet door 12.

[0067] Further, the guide rail is a groove-type rail, and the sliding device includes a roller 52 rotatably installed at the bottom of the cabinet door 12 and matched with the groove-type rail. The cabinet door 12 is fixedly provided with a roller 52 seat, and the roller 52 is rotatably installed on the roller 52 seat. The roller 52 rolls in the groove of the groove-type rail, thus realizing the opening and closing of the cabinet door 12. Specifically, the roller 52 seat includes a base 53 fixedly installed on one side of the cabinet door 12, a support rod 51 fixedly installed on the base 53, an end of the support rod 51 extending into the groove of the groove-type rail and provided with a seat plate, and the roller 52 rotatably installed on the seat plate. The central axis of the roller 52 is perpendicular to the axial direction of the groove-type rail, i.e., the roller 52 rolls along the axial direction of the groove-type rail.

[0068] Further, the opening end of the cabinet 11 is provided with a sealing ring 13 between the cabinet 11 and the cabinet door 12. When the cabinet door 12 is closed, the sealing ring 13 is pressed to seal the pre-cooling cabinet. The sealing ring 13 is preferably a rubber sealing ring 13.

[0069] Further, the translation driving device includes a cylinder 61 and a cylinder seat 62. One end of the cylinder 61 is rotationally connected to the cylinder seat 62. A driving seat 63 is installed on the cabinet door 12. The other end of the cylinder 61 is hingedly connected to the driving seat 63. The free end of the cylinder body of the cylinder 61 is hingedly connected to the cylinder seat 62. The free end of the plunger of the cylinder 61 is hingedly connected to the driving seat 63. The two hinged designs enable the cylinder 61 to automatically adapt to the position changes of the cabinet door 12. When the lifting guide rail 42 is raised, or when the cabinet door 12 is located on the fixed guide rail 41, the cabinet door 12 is in a high position. When the lifting guide rail 42 is lowered, if the cabinet door 12 is on the lifting guide rail 42, the cabinet door 12 is lowered and is in a low position.

[0070] Further, the axial direction of the cylinder 61 is arranged in the same direction as the translation direction of the cabinet door 12. The cylinder seat 62 is located outside the opening stroke end of the cabinet door 12. The driving seat 63 is located on the side of the cabinet door 12 away from the cylinder seat 62. The cylinder 61 is located above the cabinet door 12. Such arrangement of the positions of the cabinet door 12 and the cylinder 61 can obtain the maximum driving stroke in a limited space.

[0071] Further, the vacuumizing device includes a steam pipe 71 connected to the air hole of the pre-cooling cabinet. The steam pipe 71 is connected to a heat exchanger 72. The heat exchanger 72 is connected to a vacuum pump 73. The vacuum pump 73 is used to draw away the gas in the pre-cooling cabinet, so as to reduce the air pressure in the pre-cooling cabinet, thereby reducing the boiling point of water, rapidly vaporizing the water on the surface and inside of the object at low temperature, absorbing the latent heat of evaporation, thereby taking away the heat of the object itself and the environment, and achieving cooling.

[0072] Further, the steam pipe 71 is a Venturi tube. After the outlet side of the expansion section of the Venturi tube, the high-speed airflow diffuses to cause a sudden drop in pressure, forming a "vacuum zone". The gas in the pre-cooling cabinet is sucked in due to the pressure difference, achieving the function of vacuumizing.

[0073] Further, the re-pressurizing device includes a steam generator (not shown in the figure), an inlet pipe 81, and a stop valve 82. One end of the inlet pipe 81 is connected to the air hole of the pre-cooling cabinet, and the other end is connected to the steam generator. The stop valve 82 is installed on the inlet pipe 81. When the air pressure in the pre-cooling cabinet needs to be restored, the stop valve 82 is opened. The steam generated by the steam generator enters the pre-cooling cabinet through the inlet pipe 81, restoring the air pressure in the pre-cooling cabinet.

[0074] Further, asFigure 1 As shown, gantry rails 93 (not shown in the figure) are installed on both sides of the pre-cooling cabinet, and a gantry frame 94 located above the pre-cooling cabinet is slidably installed on the gantry rails 93. Items can be easily placed and removed from the top opening of the pre-cooling cabinet through the gantry frame 94.

[0075] In this horizontal vacuum precooling machine, the opening of the precooling cabinet is located at the top of the cabinet body 11, and a cabinet door 12 is installed at the opening. When items to be cooled need to be placed into the cabinet body 11, the telescopic rod 441 or the electric push rod pushes the crank arm 43 to swing, so as to... Figure 2 and Figure 10 For example, the swing arm swings counterclockwise, the top wheel 45 drives the lifting block 47 to move upward, the lifting block 47 pushes the lifting guide rail 42 to rise, and after the lifting guide rail 42 is flush with the fixed guide rail 41, the cabinet door 12 is lifted up and disengaged from the opening end of the cabinet body 11. Then the cylinder 61 works, and the cabinet door 12 moves to one side under the drive of the cylinder 61, opening the top opening of the cabinet body 11. Food that needs to be cooled can be put into the top of the cabinet body 11. The top feeding method allows the vacuum precooler to be matched with many top feeding and discharging equipment, such as braising equipment. With the same top feeding and discharging method, the material transfer and loading / unloading process can be reduced, which can not only save processes and manpower and improve work efficiency, but also reduce the risk of food contamination.

[0076] like ​ As shown, a braising production line includes a braising pot 91 and the aforementioned horizontal vacuum precooler.

[0077] The horizontal vacuum precooler adopts a top-opening structure, which is consistent with the top-opening structure of the braising pot 91. This makes it convenient for the braising basket 92 inside the braising pot 91 to be directly transported from the braising pot 91 to the precooler without intermediate transfer. This not only saves labor and improves work efficiency, but also reduces the risk of food contamination.

[0078] Furthermore, gantry rails 93 are installed on both sides of the braising pot 91 and the horizontal vacuum precooling machine. A gantry frame 94 is slidably mounted on the gantry rails 93, located above the braising pot 91 and the horizontal vacuum precooling machine. The gantry frame 94 directly transports the braising basket 92 inside the braising pot 91 to the vacuum precooling machine, resulting in high work efficiency. The ingredients to be cooked are placed in the braising basket 92. After the braising process, the gantry frame 94 transports the ingredients and the braising basket 92 together to the precooling cabinet of the vacuum precooling machine. The prepared food is only removed from the braising basket 92 after the precooling process is completed. Before the food reaches packaging conditions, the ingredients are not removed from the braising basket 92 after being placed inside, reducing the risk of food contamination.

[0079] As a specific embodiment, the marinating production line comprises a plurality of marinating pots 91 and one horizontal vacuum pre-cooling machine, the plurality of marinating pots 91 are arranged to form a marinating pot 91 sequence, and the horizontal vacuum pre-cooling machine is arranged at any end of the marinating pot 91 sequence or between any two marinating pots 91. One horizontal vacuum pre-cooling machine is matched with a plurality of marinating pots 91, so that the pre-cooling machine can be fully utilized, the idle time is reduced, and the work efficiency is improved. The number of marinating pots 91 is set according to the length of time of marinating, the capacity of the marinating pot 91, the length of time of pre-cooling food by the pre-cooling machine, and the number of food pre-cooled by the pre-cooling machine at one time. If the marinating time is consistent with the pre-cooling time, and the pre-cooling machine pre-cools four times the capacity of the marinating pot 91 at one time, then one vacuum pre-cooling machine and four marinating pots 91 need to be arranged.

[0080] Further, two gantries 94 are arranged on the gantry rail 93, one gantry 94 is used to send unmarinated food into the marinating pot 91, and the other gantry 94 is used to take out the food in the marinating pot 91 and send it into the vacuum pre-cooling machine.

[0081] As a specific embodiment, the marinating production line comprises a plurality of marinating pots 91 and a plurality of horizontal vacuum pre-cooling machines, and the marinating pots 91 and the horizontal vacuum pre-cooling machines are arranged. The skilled arrangement of the marinating pot 91 and the horizontal vacuum pre-cooling machine is referred to the principles described above.

[0082] Further, the horizontal vacuum pre-cooling machine is arranged at intervals with the marinating pot 91, one horizontal vacuum pre-cooling machine is arranged every 3-5 marinating pots 91. After the food in the marinating pot 91 is processed, it is moved to the adjacent vacuum pre-cooling machine, thereby saving the transportation distance and improving the work efficiency.

[0083] The marinating production line adopts a horizontal vacuum pre-cooling machine with a top opening, which cooperates with the top opening structure of the marinating pot 91, so as to conveniently transport the marinating basket 92 in the marinating pot 91 from the marinating pot 91 to the pre-cooling machine, without intermediate transfer, thereby saving labor, improving work efficiency, and reducing the risk of food contamination.
