Abstract
Description
Technical Field
[0001] This utility model relates to a thawing device, specifically a meat tray separation device. Background Technology
[0002] Meat trays, made of stainless steel, are used to hold and freeze food, primarily meat. They are also called freezing trays. During food processing, the frozen meat trays need to be partially thawed, not completely thawed. The purpose of this partial thaw is to separate the tray from the frozen meat inside, making it easier to process. Traditionally, this is done through a water bath, immersing the frozen meat tray in warm or hot water. However, the water used for water bath thawing easily becomes cloudy, which not only breeds bacteria but also affects the taste of the frozen meat and increases the difficulty of subsequent wastewater treatment. Therefore, improvements are urgently needed. Utility Model Content
[0003] In order to solve the above problems, the purpose of this utility model is to provide a meat plate separation device.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a meat tray separation device, including a chain conveyor belt and a heating device, wherein the heating device is driven to rise and fall above the chain conveyor belt by a lifting device, and the heating device is provided with a heating cover that fits against the upper surface of the meat tray in the inverted state, and the heating device covers the outer surface of the heating cover.
[0005] Furthermore, the rear of the chain conveyor belt of the heating device is equipped with a vibrating device that drives the lifting and lowering, and the vibrating device contacts the upper surface of the inverted meat tray after it descends.
[0006] Furthermore, the front of the chain conveyor belt of the heating device is equipped with a left-right symmetrical alignment device, which consists of multiple sets of rotating brackets with freely rotatable pulleys at their outer ends.
[0007] Furthermore, the heating device is a high-frequency induction heating coil, the lifting device is fixed on the top of the heating frame above the chain conveyor belt, the telescopic end of the lifting device is equipped with a high-frequency generator placement box, the high-frequency generator is located in the high-frequency generator placement box, and the output end of the high-frequency generator is electrically connected to the high-frequency induction heating coil to form a high-frequency induction heating device for heating stainless steel meat trays, and the upper surface of the heating cover is fixedly connected to the bottom of the high-frequency generator placement box.
[0008] Furthermore, a horizontal guide frame is provided between the heating cover and the high-frequency generator placement box. Vertical guide pulleys are provided at the four corners of the guide frame. Each guide pulley is in close contact with the vertical guide rails of the four legs of the heating frame and slides up and down along the vertical guide rails.
[0009] Furthermore, a limit baffle is provided on the front side of the heating frame, which is driven to rise and fall vertically by a cylinder. After the limit baffle is lowered, it blocks the meat tray on the front side of the heating frame. Photoelectric sensor switches for detecting the meat tray are respectively provided on the rear side of the heating cover and the chain conveyor belt frame directly below the limit baffle.
[0010] Furthermore, the vibration device consists of multiple pneumatic vibrators, each of which is vertically suspended below the lower vibration plate via telescopic rods fixed at both ends. The center of the lower vibration plate is fixedly connected to the lower telescopic end of the lifting device of the vibration device, and the lifting device of the vibration device is fixed to the top of the vibration support.
[0011] Furthermore, each telescopic rod is fitted with a rebound spring, the lower end of each rebound spring is in contact with the end of the pneumatic vibrator, and the upper end of each rebound spring is in contact with the lower surface of the pressure vibrating plate.
[0012] Furthermore, the lifting device is a vertically arranged lifting cylinder.
[0013] Furthermore, the chain conveyor belt is supported on multiple outriggers.
[0014] With the above setup, during operation, the heating device heats the stainless steel meat tray, forming an electric heating device similar to an induction cooker. This facilitates direct heating of the stainless steel meat tray, allowing for better separation of the heated meat tray from the frozen meat inside. After initial separation, to further separate the meat tray from the frozen meat, multiple vibrating devices are brought into close contact with the tray as it passes underneath. The vibrating devices then cause the heated meat tray to vibrate immediately, further separating the meat from the frozen meat. This also creates a gap between the meat tray and the frozen meat, effectively preventing the frozen meat from freezing back to the tray due to excessively low temperatures. This results in a more thorough and effective separation. This invention, which separates the meat tray from the frozen meat during thawing, not only effectively saves energy and water resources and concentrates heat on the meat tray for better separation, but also effectively prevents contamination of the frozen meat due to water baths, ensuring the food safety of the frozen meat.

[0022] like Figure 1-6 As shown, a meat tray separation device includes a chain conveyor belt 1 and a heating device 2, such as the existing chain conveyor belt 1 device, which is driven by a geared motor. The heating device 2 is driven to rise and fall above the chain conveyor belt 1 by a lifting device 3. The lifting device 3 is a vertically arranged lifting cylinder. The chain conveyor belt 1 is supported on multiple support legs, such as the commonly used chain conveyor belt 1. The heating device 2 is provided with a heating cover 4 that fits against the upper surface of the meat tray in the inverted state. The heating device 2 covers the outer surface of the heating cover 4.
[0023] Specifically: The heating device 2 is a high-frequency induction heating coil. The lifting device 3 is fixed on the top of the heating frame 8 above the chain conveyor belt 1. The telescopic end of the lifting device 3 is equipped with a high-frequency generator placement box 9. The high-frequency generator is located inside the high-frequency generator placement box 9, and the output end of the high-frequency generator is electrically connected to the high-frequency induction heating coil to form a high-frequency induction heating device for heating stainless steel meat trays, which forms an electric heating device similar to an induction cooker, making it convenient to directly heat stainless steel meat trays. The upper surface of the heating cover 4 is fixedly connected to the bottom of the high-frequency generator placement box 9. In addition, a horizontal guide frame 10 is provided between the heating cover 4 and the high-frequency generator placement box 9. Vertical guide pulleys 11 are provided at the four corners of the guide frame 10. Each guide pulley 11 is in close contact with the vertical guide rails 12 of the four support legs of the heating frame 8 and slides up and down along the vertical guide rails 12 to play a guiding and supporting role.
[0024] To facilitate blocking the meat tray in front of the heating tray during heating, a limit baffle 13 is provided on the front side of the heating frame 8, which is driven vertically by a cylinder. After the limit baffle 13 is lowered, it blocks the meat tray in front of the heating frame 8. Photoelectric sensor switches 14 for detecting the meat tray are respectively provided on the rear side of the heating cover 4 and the frame of the chain conveyor belt 1 directly below the limit baffle 13. In addition, for better operation, i.e., to replace manual control, it can be controlled by setting up a PLC control cabinet (not shown). A complete control program can be formed by the existing technicians through program adaptation and adjustment. The above PLC control program will not be described again.
[0025] To facilitate faster and more efficient separation of the meat after heating the meat tray, a vibrating device 5 is installed at the rear of the chain conveyor belt 1 of the heating device 2 via a rear lifting device 3. The vibrating device 5 descends and contacts the upper surface of the inverted meat tray. The vibrating device 5 consists of multiple pneumatic vibrators, which are existing technology and their structure will not be described in detail here. Each pneumatic vibrator is vertically suspended below the lower vibrating plate 16 via telescopic rods 15 fixed at both ends. For example, there are five pneumatic vibrators in total, four at the four corners of the lower vibrating plate 16 and the fifth at the center of the lower vibrating plate 16. This ensures more comprehensive contact with the bottom surface of the meat tray after it has been inverted, resulting in more complete vibration of the meat tray and better vibration separation. The center of the lower vibration plate 16 is fixedly connected to the lower telescopic end of the lifting device 3 of the vibration device 5. The lifting device 3 of the vibration device 5 is fixed to the top of the vibration bracket 17. Each telescopic rod 15 is fitted with a rebound spring 18. The lower end of each rebound spring 18 contacts the end of the pneumatic vibrator, and the upper end of each rebound spring 18 contacts the lower surface of the lower vibration plate 16. The telescopic rods 15 and the rebound springs 18 better connect the vibration device 5 with the meat tray.
[0026] The front of the chain conveyor belt 1 of the heating device 2 is provided with a left-right symmetrical straightening device. The straightening device is composed of multiple sets of rotating brackets 6 with freely rotating pulleys 7 at their outer ends. As in the utility model patent applied for by the applicant on the same day, entitled "A Mobile Straightening Device", its structure will not be described in detail here.
[0027] The working principle of this utility model is as follows: First, the meat tray (also called the frozen tray) is placed upside down on the chain conveyor belt 1 between the left and right rotating supports. During the conveying process, the meat tray is straightened. When the upside-down meat tray moves directly under the heating cover 4, the photoelectric sensor switch 14 detects it. The lifting device 3 of the heating frame 8 lowers the heating cover 4 and catches the meat tray that is already in place inside the heating frame 8. The front side of the heating frame 8 is provided with a limit baffle 13 that is driven vertically by a cylinder. At this time, after the limit baffle 13 is lowered, it blocks the meat tray on the front side of the heating frame 8. The output end of the high frequency generator is electrically connected to the high frequency induction heating coil to form a high frequency induction heating device. The heating device 2 heats the stainless steel meat tray, which forms an electric heating device similar to an induction cooker, which facilitates direct heating of the stainless steel meat tray. This allows the heated meat tray to be better separated from the frozen meat inside. After the initial separation by heating, the lifting device 3 of the heating frame 8 raises the heating cover 4, and the frozen tray continues to be conveyed backward by the chain conveyor belt.
[0028] To further separate the meat tray from the frozen meat inside, when the heated meat tray passes under the vibrating device 5, the lifting device 3 of the vibrating support 17 lowers the lowering vibrating plate 16, so that multiple vibrating devices 5 come into close contact with the meat tray passing by. The vibrating devices 5 work, thereby causing the heated meat tray to vibrate immediately, further separating the meat tray from the frozen meat. This also creates a certain gap between the meat tray and the frozen meat, effectively preventing the frozen meat from freezing together with the meat tray again due to its low temperature, making the separation of the meat tray and the frozen meat more thorough and the separation effect better. After vibration, the lowering vibrating plate 16 and the vibrating device 5 rise, and the separated meat tray and frozen meat are transported to the rear end of the chain conveyor belt. The meat tray can be easily removed manually or by a robotic arm, and the frozen meat is sent to subsequent processing equipment.
[0029] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
