Description

Technical Field

[0001] The invention relates to the technical field of food processing, in particular to a quick-freezing machine used for food processing. Background Art

[0002] The quick freezer is a highly efficient freezing device that can freeze a large number of products in a short period of time. It can effectively and economically freeze a variety of products placed inside the quick freezer, such as meat, fish, shrimp, meatballs, vegetables, prepared foods, dairy products, etc. in various shapes. Some quick-frozen foods also need to be quick-frozen after packaging.

[0003] In the prior art, after quick-frozen food is packaged, it is transported to a quick-freezing machine via a conveyor belt and, after being frozen, is packaged and boxed.

[0004] However, since the temperature of quick-frozen food is low after production, the temperature difference between the inside and outside of the packaging bag makes it easy for moisture to precipitate on the surface of the packaging bag. After the conveyor transports it through the quick-freezer, the moisture on the surface solidifies, which can easily freeze the food bag on the conveyor belt, affecting the subsequent packaging process.

DETAILED DESCRIPTION

[0038] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0039] See also Figures 1 to 13 The present invention provides a technical solution: a quick freezer for food processing, comprising a quick freezer 1, workbenches 11 are respectively installed on both sides of the quick freezer 1, a conveying device 2 for driving food to pass through the quick freezer 1 is installed above the quick freezer 1 and the workbenches 11, and a conveyor belt 21 is driven on the conveying device 2;

[0040] The conveying device 2 passes through the quick freezer 1, so that the food to be quick-frozen is placed on the starting point of the conveyor belt 21. With the relative movement of the conveyor belt 21, the food is driven to pass horizontally through the quick freezer 1 for quick freezing operation.

[0041] The part of the conveying device 2 located in the quick freezer 1 is provided with an adsorption roller 211, and the adsorption roller 211 adsorbs excess moisture on the surface of the food on the conveying device 2;

[0042] When the food moves along the conveyor belt 1, the adsorption roller 211 absorbs the moisture on the surface of the food to prevent the moisture on the surface of the food from freezing during the quick freezing process and solidifying the food on the surface of the conveyor belt 21, which affects the subsequent packaging and transportation process.

[0043] A collecting box 4, wherein the collecting box 4 is arranged above the adsorption roller 211, and the collecting box 4 scrapes off the moisture adsorbed on the surface of the adsorption roller 211 to prevent the adsorption roller 211 from freezing;

[0044] The collecting box 4 is used to scrape off the moisture adsorbed on the surface of the adsorption roller 211, thereby preventing the moisture adsorbed inside the adsorption roller 211 from freezing during its operation in the quick-freezing machine 1, which would cause the adsorption roller 211 to be unable to effectively adsorb moisture on the food surface.

[0045] The conveying device 2 is provided with a second lifting plate 64 above the side away from the adsorption roller 211 in the quick freezer 1, and a scraper 65 is provided on the part of the second lifting plate 64 parallel to the conveying device 2. The scraper 65 separates the food frozen on the conveyor belt 21 for subsequent packaging and transportation of the food.

[0046] Even if the moisture on the surface of the food is adsorbed, the moisture inside the quick freezer 1 will still freeze the food on the surface of the conveyor belt 21, but the freezing strength at this time is not high. Through the structure of the scraper 65, the food is separated from the conveyor belt 21 when it is about to pass through the quick freezer 1.

[0047] The conveying device 2 horizontally penetrates the quick freezer 1, and wind shields 12 are respectively provided on both sides of the quick freezer 1. The lower part of the wind shield 12 hangs down to the surface of the conveyor belt 21. The part of the quick freezer 1 located below the conveying device 2 is provided with a lower cold air port 13, and the top of the quick freezer 1 is provided with an upper cold air port 14. The upper cold air port 13 and the lower cold air port 14 simultaneously inject cold air into the part of the quick freezer 1 located within the wind shield 12.

[0048] The structure of the wind shield 12 isolates the inside and outside of the quick freezer 1 to prevent the internal cold air from overflowing and causing the internal refrigeration effect of the quick freezer 1 to decrease. Cold air is simultaneously transported to the inside through the upper cold air port 13 and the lower cold air port 14 to ensure that the food is frozen evenly in the quick freezer 1.

[0049] The conveying device 2 is provided with a first driven wheel 22 at an initial position of the moving direction of the conveying belt 21, and the first driven wheel 22 is transmission connected to the conveying belt 21. A first transmission wheel 24 is provided on the side of the first driven wheel 22 away from the conveying device 2, and the first transmission wheel 24 rotates coaxially with the first driven wheel 22. A second transmission wheel 25 is provided above the first transmission wheel 24, and the first transmission wheel 24 and the second transmission wheel 25 are transmission connected via a belt 26.

[0050] After the conveying device 2 is started, the conveyor belt 21 runs, driving the first driven wheel 22 to rotate, so that the first transmission wheel 24 rotates coaxially with the first driven wheel 22, and under the transmission action of the belt 26, the second transmission wheel 25 rotates in the same direction as the first transmission wheel 24.

[0051] A rotating column 28 is installed on the side of the second transmission wheel 25 facing the conveyor belt 21, and the rotating column 28 is set to be L-shaped. One end of the rotating column 28 is fixed to the axis of the second transmission wheel 25, and the other end of the rotating column 28 is sleeved with a movable column 210, and the movable column 210 is slidably connected to the rotating column 28. A first spring 29 is arranged between the movable column 210 and the rotating column 28, one end of the first spring 29 is fixedly connected to the rotating column 28, and the other end of the first spring 29 is fixedly connected to the inner wall of the movable column 210, and the end of the movable column 210 away from the rotating column 28 is installed with the adsorption roller 211, and the adsorption roller 211 is rotatably connected to the movable column 210.

[0052] During the rotation of the second transmission wheel 25, the rotating column 28 is driven to rotate. With the cooperation of the movable column 210, the adsorption roller 211 performs periodic circular motion above the conveyor belt 21, so that after each food bag passes under the adsorption roller 211, the adsorption roller 211 will contact the top of the food bag and adsorb the water on the surface of the food bag and the water flowing from the surface to the surface of the conveyor belt 21. Under the elastic force of the first spring 29, the adsorption roller 211 slides in the direction away from the rotating column 28, that is, the adsorption roller 211 will fit closely with the upper surface of the conveyor belt 21 during the rotation process, so as to better adsorb the moisture on the surface of the food bag and the surface of the conveyor belt 21.

[0053] The part of the rotating column 28 coaxial with the second transmission wheel 25 is fixedly connected with a gear 27, and the rotating column 28 rotates coaxially with the gear 27. A tooth block is provided on the side of the gear 27 away from the adsorption roller 211, and a rack 35 is provided on one side of the gear 27. The tooth block of the gear 27 is meshed with the rack 35 for transmission, and a lifting column 32 is fixedly connected to the side of the rack 35 away from the gear 27. The lower part of the lifting column 32 is arranged in a fixed column 33, and the lifting column 32 is vertically slidably connected to the fixed column 33. The fixed column 33 is installed on the inner wall of the quick-freezing machine 1, and a second spring 34 is provided between the fixed column 33 and the lifting column 32, and the two ends of the second spring 34 are fixedly connected to the fixed column 33 and the lifting column 32 respectively.

[0054] During the rotation of the rotating column 28, the gear 27 and the second transmission wheel 25 rotate in the same direction and at the same speed. During the upward rotation of the adsorption roller 211, the tooth block of the gear 27 meshes with the rack 35 and drives the rack 35 to move downward, so that the rack 35, i.e., the lifting column 32, slides synchronously into the fixed column 33.

[0055] When the adsorption roller 211 rotates downward, the tooth block of the gear 27 separates from the rack 35, so that the rack 35 loses its downward restraining force. Under the elastic force of the second spring 34, the lifting column 32 slides upward, causing the rack 35 to slide upward to the initial position.

[0056] A first lifting plate 3 is fixedly connected to the top of the lifting column 32, a collecting box 4 is arranged above the first lifting plate 3, the collecting box 4 is installed above the quick-freezing machine 1, the collecting box 4 is arranged in a trapezoidal shape, a scraper 41 is arranged on the hypotenuse of the collecting box 4, one end of the scraper 41 is rotatably mounted on the collecting box 4 through an axis, and the other end of the scraper 41 is an opening and closing end, a first connecting rope 31 is installed above the first lifting plate 3, and the other end of the first connecting rope 31 is connected to the bottom of the opening and closing end of the scraper 41.

[0057] When the lifting column 32 slides downward, the first lifting plate 3 moves downward, that is, the first connecting rope 31 is tightened and contracts downward, so that the other end of the first connecting rope 31 pulls the opening and closing end of the scraper 41 to flip downward, that is, the scraper 41 opens to the bottom of the collection box 4.

[0058] A reset assembly 42 is provided above the inner wall of the collecting box 4, and a slider 43 is slidably connected in the reset assembly 42. A third spring 44 is provided on the side of the slider 43 facing the inner wall of the collecting box 4, and both ends of the third spring 44 are fixedly connected to the slider 43 and the inner wall of the reset assembly 42 respectively. A second connecting rope 45 is fixedly connected to the other side of the slider 43, and the second connecting rope 45 is connected to the upper part of the opening and closing end of the scraper 41. A drainage pipe 46 is provided on the right-angled side below the collecting box 4, and the lower part of the drainage pipe 46 is connected to the upper part of the water tank 5 installed in the quick-freezing machine 1, and the rotating column 28 periodically collides with the outer wall of the drainage pipe 46.

[0059] After the gear 27 is separated from the rack 35, the first lifting plate 3 slides upward, so that the first connecting rope 31 is loosened, and the first connecting rope 31 loses its binding force on the scraper 41. Under the elastic force of the third spring 44, the slider 43 slides toward the inside of the reset assembly 42, so that the second connecting rope 45 pulls the opening and closing end of the scraper 41 upward, so that the scraper 41 and the collection box 4 are closed, preventing the water in the collection box 4 from flowing into the conveyor belt 21 again along the opening between the scraper 41 and the collection box 4;

[0060] The downward force applied by the gear 27 to the rack 35 is greater than the sum of the maximum elastic forces of the second spring 34 and the third spring 44;

[0061] Under the elastic force of the first spring 29, the rotating column 28 and the movable column 210 can be extended and retracted, so that the adsorption roller 211 gradually shrinks inward after rotating to the oblique edge of the collecting box 4, and pops out again after passing through the collecting box 4. At this time, the position where the adsorption roller 211 pops out is opposite to the drainage tube 46, so that the adsorption roller 211 collides with the drainage tube 46, avoiding condensation of water inside the collecting box 4, resulting in the inability to discharge it into the water tank 5. At the same time, the scraper 41 scrapes the water off the adsorption roller 211 and prevents it from entering the collecting box 4.

[0062] The conveying device 2 is provided with a second driven wheel 23 at the end position of the moving direction of the conveyor belt 21. The second driven wheel 23 is fixedly connected to a limiting rod 212 away from the non-axial part of the conveyor belt 21. A movable frame 6 is sleeved on the limiting rod 212. The movable frame 6 is movably connected to the limiting rod 212. A positioning rod 61 is provided at the end of the movable frame 6 facing the quick freezer 1. The positioning rod 61 is fixed on the side wall of the conveying device 2, and the movable frame 6 is rotatably connected to the positioning rod 61.

[0063] A telescopic rod 62 is provided at the end of the movable frame 6 away from the positioning rod 61, and the fixed end of the telescopic rod 62 is fixedly connected to the movable frame 6, and the movable end of the telescopic rod 62 is hinged to the lower end of the connecting column 63, and the upper end of the connecting column 63 is fixedly connected to a second lifting plate 64, and the middle part of the second lifting plate 64 is provided with the scraper 65, the width of the scraper 65 is consistent with the conveyor belt 21, and the direction of the scraper 65 is opposite to the moving direction of the conveyor belt 21, and the two ends of the second lifting plate 64 are arranged in the limit groove 66, and the second lifting plate 64 is vertically slidably connected to the limit groove 66, and the limit groove 66 is fixedly connected to the inner wall of the quick-freezing machine 1.

[0064] The operation of the conveyor belt 21 synchronously drives the second driven wheel 23 to rotate, and the limiting rod 212 changes position following the rotation of the second driven wheel 23, and the positioning rod 61 fixes the position of one end of the movable frame 6, so that the movable frame 6 takes the positioning rod 61 as the center of the circle and swings up and down according to the position of the limiting rod 212, that is, the telescopic rod 62 swings up and down, and because the limiting groove 66 limits the sliding distance and direction of the second lifting plate 64, the connecting column 63 drives the second lifting plate 64 to move up and down, so that the scraper 65 can be lowered to the upper surface of the conveyor belt 21, and when the food bag passes through the scraper 65, the food bag is separated from the upper surface of the conveyor belt 21;

[0065] At the same time, since the running speed of the conveyor belt 21 is constant, the rotation speeds of the first driven wheel 22 and the second driven wheel 23 are kept consistent, so that the frequency of the adsorption roller 211 and the scraper 65 moving toward the surface of the conveyor belt 21 is consistent. Therefore, by controlling the placement spacing of the food bags on the conveyor belt 21, the adsorption roller 211 and the scraper 65 can synchronously process the food bags on the conveyor belt 21.

[0066] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
