Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a rapid freezing device for food. Background Technology

[0002] Some foods that require freezing need to be frozen after processing before being repackaged and shipped. Currently, the freezing process involves using a tunnel-type freezer after production, where food is fed into a box-type freezer via a conveyor belt for initial freezing. While this method is highly efficient, it has drawbacks. Some foods are large or have irregular shapes, resulting in uneven freezing, while others are smaller and freeze more evenly. This makes it difficult for the freezer to adjust the cooling according to actual needs. Utility Model Content

[0003] The purpose of this invention is to provide a rapid freezing device for food, which solves the aforementioned problems existing in current freezing devices.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A rapid freezing device for food includes a tunnel freezing chamber, a first conveyor belt, a second conveyor belt, and a third conveyor belt disposed within the tunnel freezing chamber. The first, second, and third conveyor belts are arranged sequentially at intervals. The conveying direction of the second conveyor belt is opposite to that of the first and third conveyor belts. The second conveyor belt is connected to a belt shifting mechanism for driving the input end of the second conveyor belt to protrude beyond the output end of the first conveyor belt. Food is output through the output end of the first conveyor belt, or, after falling into the input end of the second conveyor belt, is output through the third conveyor belt.

[0006] Furthermore, a groove is provided along the length direction on the inner wall of the tunnel freezing box, and a sliding strip is provided on the side of the second conveyor belt. The second conveyor belt is slidably disposed in the tunnel freezing box through the cooperation of the sliding strip and the groove. The belt shifting mechanism is connected to the sliding strip, and the second conveyor belt is driven to move along the tunnel freezing box through the belt shifting mechanism to drive the input end of the second conveyor belt to protrude out of the output end of the first conveyor belt.

[0007] Furthermore, the conveyor belt shifting mechanism includes a cylinder and a drive connecting block. An avoidance groove is provided on the outer wall of the tunnel freezing box. The cylinder is located on the outer wall of the tunnel freezing box. One end of the drive connecting block is connected to the output shaft of the cylinder, and the other end passes through the avoidance groove and is connected to the slide bar. The cylinder drives the input end of the second conveyor belt to protrude from the output end of the first conveyor belt.

[0008] Furthermore, the tunnel freezing box is provided with a discharge conveying mechanism on one side of the output end of the first conveyor belt. The discharge conveying mechanism includes a discharge conveyor belt and a lifting mechanism. The lifting mechanism drives the discharge conveyor belt to connect with the output end of the first conveyor belt or to connect with the output end of the third conveyor belt.

[0009] Furthermore, the lifting mechanism includes a base, a support frame, and a drive mechanism. The lower end of the support frame is slidably inserted into the base in the vertical direction, and the upper end is connected to the discharge conveyor belt. The drive mechanism drives the support frame to move up and down along the base. The base is provided with a locking knob for positioning the support frame.

[0010] Furthermore, the driving mechanism includes a screw and a turntable. The upper end of the screw is fixedly connected to the support frame and sleeved in the base. The turntable is threadedly connected to the screw and abuts against the base. By rotating the turntable, the support frame is driven to move up and down to adjust the height of the discharge conveyor belt.

[0011] The beneficial effects of this utility model are:

[0012] This invention relates to a rapid freezing device for food. By setting up a first, second, and third conveyor belt with vertical spacing and adjustable conveying direction, it can flexibly freeze foods of different sizes and shapes. For smaller, uniformly frozen foods, they can be directly conveyed through the first conveyor belt. For larger, irregularly shaped, or unevenly frozen foods, the second conveyor belt can be moved by a belt shifting mechanism to receive the food and further freeze it, thereby greatly improving freezing efficiency and uniformity. The belt shifting mechanism allows the second conveyor belt to be adjusted in position according to actual needs, enhancing the adaptability and flexibility of the device.

[0013] Furthermore, through the cooperation of the lifting mechanism and the drive mechanism, the discharge conveyor belt can be easily connected to the output end of the first or third conveyor belt, thereby simplifying the discharge process. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0039] Please see Figures 1 to 5 A rapid freezing device for food includes a tunnel freezing chamber 1, a first conveyor belt 2, a second conveyor belt 3 and a third conveyor belt 4 disposed in the tunnel freezing chamber 1.

[0040] like Figure 1 and Figure 2 As shown, the first conveyor belt 2, the second conveyor belt 3, and the third conveyor belt 4 are arranged sequentially, one above the other, at intervals. The conveying direction of the second conveyor belt 3 is opposite to that of the first conveyor belt 2 and the third conveyor belt 4. The second conveyor belt 3 is connected to a belt shifting mechanism 5, which drives the input end of the second conveyor belt 3 to protrude beyond the output end of the first conveyor belt 2. Food is output through the output end of the first conveyor belt 2, or falls into the input end of the second conveyor belt 3 and is then output via the third conveyor belt 4.

[0041] With this configuration, food enters the tunnel freezer 1 from the input end of the first conveyor belt 2 for initial freezing. Smaller foods that are frozen relatively evenly can be directly discharged from the output end of the first conveyor belt 2. Larger foods, or those with irregular shapes or uneven freezing, are moved by the conveyor belt shifting mechanism 5, causing the input end of the second conveyor belt 3 to protrude beyond the output end of the first conveyor belt 2. These foods then fall onto the second conveyor belt 3 for further freezing and are finally discharged via the third conveyor belt 4. This configuration allows for flexible adjustment based on the actual freezing requirements of the food, improving the adaptability and freezing effect of the freezing device.

[0042] It should be noted that the technical principle of using tunnel freezing boxes for freezing is existing technology and will not be elaborated here.

[0043] Furthermore, such as Figure 2 and Figure 3 As shown, a chute (not shown) is provided along the length of the inner wall of the tunnel freezing box 1. A sliding strip 7 is provided on the side of the second conveyor belt 3. The second conveyor belt 3 is slidably disposed in the tunnel freezing box 1 through the cooperation of the sliding strip 7 and the chute. The belt shifting mechanism 5 is connected to the sliding strip 7. The belt shifting mechanism 5 drives the second conveyor belt 3 to move along the tunnel freezing box 1, so as to drive the input end of the second conveyor belt 3 to protrude beyond the output end of the first conveyor belt 2.

[0044] Specifically, the conveyor belt shifting mechanism 5 includes a cylinder 51 and a drive connecting block 52. A clearance groove 8 is provided on the outer wall of the tunnel freezing box 1. The cylinder 51 is mounted on the outer wall of the tunnel freezing box 1. One end of the drive connecting block 52 is connected to the output shaft of the cylinder 51, and the other end passes through the clearance groove 8 and is connected to the slide bar 7. Through the extension and retraction movement of the cylinder 51, the second conveyor belt 3 can be driven to move along the tunnel freezing box 1, thereby adjusting the relative position between the input end of the second conveyor belt 3 and the output end of the first conveyor belt 2.

[0045] In addition, such as Figure 1 and Figure 5 As shown, the tunnel freezing box 1 is equipped with a discharge conveying mechanism 9 on one side of the output end of the first conveyor belt 2. The discharge conveying mechanism 9 includes a discharge conveyor belt 91 and a lifting mechanism 92. The lifting mechanism 92 drives the discharge conveyor belt 91 to connect with the output end of the first conveyor belt 2 or with the output end of the third conveyor belt 4. The height and position of the discharge conveyor belt 91 can be easily adjusted to adapt to the discharge requirements of different conveyor belts.

[0046] Specifically, Figure 5 As shown, the lifting mechanism 92 includes a base 921, a support frame 922, and a drive mechanism 923. The lower end of the support frame 922 is slidably inserted into the base 921 in the vertical direction, and the upper end is connected to the discharge conveyor belt 91. The drive mechanism 923 is used to drive the support frame 922 to move up and down along the base 921. The base 921 is provided with a locking knob 924 for positioning the support frame 922. Through the cooperation of the drive mechanism 923 and the locking knob 924, the height and position of the discharge conveyor belt 91 can be precisely adjusted.

[0047] More specifically, the drive mechanism 923 includes a screw 9231 and a turntable 9232. The upper end of the screw 9231 is fixedly connected to the support frame 922 and is sleeved in the base 921. The turntable 9232 is threadedly connected to the screw 9231 and abuts against the base 921. By rotating the turntable 9232, the support frame 922 can be driven to move up and down along the base 921, thereby adjusting the height of the discharge conveyor belt 91.

[0048] The food rapid freezing device of this utility model achieves rapid and uniform freezing of food by setting up a first conveyor belt 2, a second conveyor belt 3 and a third conveyor belt 4 with vertical spacing and opposite conveying directions, as well as a mesh belt shifting mechanism 5 and a discharge conveying mechanism 9 that cooperate with them, and improves the adaptability and flexibility of the freezing device.

[0049] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
