Description

Technical Field

[0001] This utility model relates to the field of dispersing device technology, specifically to a dispersing mechanism for a fluidized quick-freezing device. Background Technology

[0002] A fluidized bed freezer is a device that uses fluidized bed technology for rapid freezing. It creates a suspension state, allowing the freezing medium (usually liquid nitrogen or carbon dioxide) to fully contact food or other materials, thus achieving rapid cooling and freezing. This technology not only accelerates the cooling process but also freezes items more uniformly, significantly improving freezing efficiency and the final quality of the product.

[0003] During fluidized bed freezing, the frozen products tend to stick together due to environmental factors such as temperature and humidity, making them difficult to separate. Usually, the products that are stuck together are separated manually, but this method is not only slow and time-consuming, but also cannot guarantee safety and hygiene, and cannot meet production needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dispersing mechanism for a fluidized bed quick-freezing device, which can separate products that are stuck together after freezing, thereby improving quick-freezing efficiency.

[0006] A dispersing mechanism for a fluidized bed quick-freezing device includes a vibrating screen disposed below a conveyor belt. A discharge channel is provided between the discharge end of the conveyor belt and the feed end of the vibrating screen to separate adhered products by impact. The discharge channel includes a fixed plate and an adjusting plate disposed opposite to each other. Two first inclined plates are disposed vertically at intervals on one side of the fixed plate opposite to the adjusting plate, and two second inclined plates are disposed vertically at intervals on one side of the adjusting plate opposite to the fixed plate. The first and second inclined plates are staggered and their inclination directions are opposite. The discharge end of the vibrating screen is provided with a screen outlet for individual products to pass through, and a discharge box for collecting products is disposed below the screen outlet.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] A dispersing mechanism for a fluidized bed quick-freezing apparatus, such as Figures 1 to 2 As shown, it includes a vibrating screen located below the conveyor belt 1. A discharge channel 2 is provided between the discharge end of the conveyor belt 1 and the feed end of the vibrating screen. The discharge channel 2 can impact the sticky products to separate them. At the same time, it works in conjunction with the vibration force of the vibrating screen to separate the sticky products, so that the products are formed into individual products that meet the production specifications.

[0017] The material feeding channel 2 includes a fixed plate 21 and an adjusting plate 23 arranged opposite to each other. Two first inclined plates 22 are arranged vertically at intervals on one side of the fixed plate 21 opposite to the adjusting plate 23, and two second inclined plates 24 are arranged vertically at intervals on one side of the adjusting plate 23 opposite to the fixed plate 21. The first inclined plates 22 and the second inclined plates 24 are staggered.

[0018] When the conveyor belt 1 delivers the quick-frozen product to the discharge channel 2, the second inclined plate 24 initially impacts the product, causing it to fall onto the first inclined plate 22 below. Then, it bounces back onto the second inclined plate 24 below, and finally passes through the first inclined plate 22 below to the vibrating screen. During this process, the sticky products separate and fall onto the vibrating screen during multiple bounces and collisions.

[0019] The vibrating screen is provided with a screen outlet 7 at the discharge end for individual products to pass through, and a discharge box 6 for collecting products is provided below the screen outlet 7.

[0020] The vibrating screen includes a screen 3, which is connected to the bottom plate 4 below via an elastic connector 10. The lower end of the elastic connector 10 is connected to the lower connecting seat 8 on the bottom plate 4, and the upper end of the elastic connector 10 is connected to the upper connecting seat 9, which is located on the side of the screen 3.

[0021] The elastic connector 10 can be a spring with strong support, or other elastic connectors can be selected as needed.

[0022] The base plate 4 is also equipped with a drive mechanism that drives the screen 3 to vibrate, and a cover 5 is provided above the drive mechanism to protect it.

[0023] The driving mechanism includes a connecting plate 16 connected to the feed end of the screen 3 and a rotating wheel 12 driven by a motor 11. The motor 11 is mounted on the base plate 4 via a motor mounting seat 18. An eccentric shaft 13 is provided on the rotating wheel 12. The bottom of the connecting plate 16 is connected to one end of a moving rod 15 that passes through the cover 5. The other end of the moving rod 15, located inside the cover 5, is hinged to a connecting rod 14. The other end of the connecting rod 14 is hinged to the eccentric shaft 13. A support seat 17 that is slidably connected to the moving rod 15 is also provided on the base plate 4.

[0024] When the motor 11 drives the rotating wheel 12 to rotate, the eccentric shaft 13 is eccentrically set relative to the center of the rotating wheel 12. Therefore, the eccentric shaft 12 drives the connecting rod 14 to change, thereby driving the moving rod 15 to move horizontally and causing the screen 3 to vibrate, thus separating the stuck products.

[0025] In addition, the bottom of the fixed plate 21 is fixedly connected to the base plate 4, and the adjusting plate 23 is installed on the screen 3 near the feed end. When the screen 3 vibrates under the action of the drive mechanism, the adjusting plate 23 will move with the screen 3. As the adjusting plate 23 moves closer to the fixed plate 21, it will generate a certain impact force, thereby knocking the stuck products apart and forming a linkage effect.

[0026] When in use, start the motor 11, which drives the screen 3 to vibrate through the drive mechanism. At this time, the product falls from the conveyor belt 1 and is repeatedly bounced and impacted in the material drop channel 2, breaking up the sticky products. At the same time, the adjusting plate 23 moves with the screen 3, forming a certain impact on the sticky products, so that the products that are not deeply stuck are separated.

[0027] Subsequently, the product enters the screen 3 along the feeding channel 2. The screen 3 generates vibration force under the drive mechanism, which vibrates and separates the products that are more stuck together, and sends the products to the discharge box 6 for collection through the screen outlet 7.

[0028] This utility model provides a dispersing mechanism for a fluidized bed quick-freezing device. By setting a material drop channel between the conveyor belt outlet and the vibrating screen, and setting opposing first and second inclined plates in the material drop channel, multiple rebounds of material drop are formed. The impact during the rebounds initially separates products that are not deeply stuck together. Then, the vibrating screen further separates products that are severely stuck together, thereby improving the separation effect and effectively separating products that are stuck together into individual products.
