[0016] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.
[0017] Please refer to Figures 1 to 4 As shown, the freezing system for producing frozen large yellow croaker of the present invention comprises: The platform 1 is provided with more than three limiting vertical plates 11 at intervals, a conveying channel 12 is provided between two adjacent limiting vertical plates 11, a vertical conveyor belt group 13 is provided in the conveying channel 12, and the vertical conveyor belt group 13 is used to clamp and convey the large yellow croaker; The guide column 2 is slidably arranged on the platform 1, and the vertical conveyor belt group 13 is sent out from one conveying channel 12 and then turns through the guide column 2 and enters another adjacent conveying channel 12; The elastic member 3 is connected to the platform 1 and the guide column 2 respectively, and the elastic member 3 is used to support the guide column 2 in a direction away from the limiting vertical plate 11.
[0018] From the above description, it can be seen that the beneficial effects of the present invention are: a freezing system for producing frozen large yellow croaker, a platform 1 specially designed for conveying large yellow croaker, a limiting plate 11 and a guide column 2 are arranged on the platform 1, a vertical conveyor belt group 13 can clamp the large yellow croaker, the limiting plate 11 forms a conveying channel 12, and the guide column 2 has a steering and traction function, so that the vertical conveyor belt group 13 conveys the large yellow croaker along an S-shaped route on the platform 1, and the large yellow croaker is drained in the straight conveying section. The vertical conveyor belt group 13 passes through the guide column 2, and under the action of the elastic member 3, the guide column 2 has a tendency to move away from the limiting plate 11. When the large yellow croaker passes the first guide column 2 along the vertical conveyor belt, the guide column 2 compresses the spring and slides on the platform 1, so that The size of the angle formed by the guide column 2 and the two adjacent conveying channels 12 can be adaptively adjusted according to the size of the yellow croaker. Small fish match a larger angle, and large fish match a smaller angle. While ensuring the drainage effect, excessive squeezing and damage to the fish meat are avoided. The yellow croaker body is bent in one direction along with the vertical conveyor belt group 13, so that the processing liquid and mucus remaining in the fish body and fish belly are squeezed out. After that, when the yellow croaker is conveyed by the vertical conveyor belt through the second guide column 2, the yellow croaker body is bent in the opposite direction along with the vertical conveyor belt group 13 to further drain the residual liquid. In this way, the excess liquid impurities of the pickled yellow croaker can be fully removed before freezing and packaging, so as to avoid the fishy smell of the yellow croaker product when it is eaten later, thereby improving the quality of the product.
[0019] In an optional embodiment, the vertical conveyor belt set 13 includes two vertical conveyor belts 131 moving synchronously.
[0020] From the above description, it can be seen that the two vertical conveyor belts 131 move synchronously, firmly and stably clamp the large yellow croaker body and convey it along a preset path. The advantages of vertical conveying are that it can improve the efficiency of draining impurities and that it is conducive to the uniformity of subsequent air-cooling freezing on both sides of the fish body, thereby improving the freezing quality.
[0021] In an optional embodiment, drainage holes are provided on the surface of the vertical conveyor belt 131 .
[0022] From the above description, it can be seen that the function of the drain hole is to enable the contact area between the fish body and the vertical conveyor belt 131 to also have the function of draining liquid, so as to ensure that the processing liquid, mucus, etc. are fully drained out.
[0023] In an optional embodiment, a side wall of the limiting vertical plate 11 is provided with a rotating column 111 for limiting the vertical conveyor belt 131 .
[0024] From the above description, it can be seen that the function of the rotating column 111 is to limit the vertical conveyor belt 131, control the distance and direction of the two vertical conveyor belts 131 in the conveying channel 12, and ensure that the fish body is stably clamped.
[0025] In an optional embodiment, a drain port 14 is provided at a position of the platform 1 corresponding to the conveying channel 12 .
[0026] From the above description, it can be known that the function of the drain port 14 is to quickly discharge the processing liquid, mucus, etc. drained from the previous large yellow croaker from the table to prevent them from adhering to the large yellow croaker that is subsequently transported.
[0027] In an optional embodiment, an arc groove 21 is provided on the surface of the guide post 2 along the circumferential direction.
[0028] From the above description, it can be seen that the purpose of designing the arc groove 21 is to better fit the shape of the fish body and increase the pressure area of the guide column 2 on the fish body, so that the processing liquid and mucus remaining in the fish body and fish belly can be fully squeezed out, while avoiding damage to the fish meat.
[0029] In an optional embodiment, an annular rubber layer is provided on the surface of the arc-shaped groove 21 .
[0030] From the above description, it can be seen that the annular rubber layer plays a role in increasing friction and buffering protection. The rubber layer with elastic deformation ability can increase the pressure area on the fish body and can adaptively deform according to the size of the fish during the passage of the fish to avoid damage to the fish meat.
[0031] In an optional embodiment, two adjacent limiting upright plates 11 are respectively provided with staggered arc-shaped bosses 112 on two oppositely disposed surfaces.
[0032] From the above description, it can be seen that one row of arc-shaped bosses 112 is provided on one limiting vertical plate 11, and another row of arc-shaped bosses 112 is provided on another limiting vertical plate 11. The two rows of arc-shaped bosses 112 are arranged alternately and staggered, so that the conveying channel 12 becomes an S-shaped route. During the clamping and conveying process of the fish on the vertical conveyor belt group 13, the two rows of arc-shaped bosses 112 continuously and alternately limit and squeeze the fish body, so that the fish body is continuously twisted and conveyed in the conveying channel 12, thereby continuously and multi-directionally forcing the residual processing liquid and mucus in the fish body and fish belly to be fully squeezed and drained. Compared with the vibration drainage method, the risk of fish meat damage can be reduced.
[0033] In an optional embodiment, an air cooler 4 is provided above the platform 1 , and the air cooler 4 is provided with an air outlet arranged toward the conveying passage 12 .
[0034] From the above description, it can be seen that the air cooler 4 cooperates with the drainage structure to drain impurities and preliminarily freeze the large yellow croaker at the same time, and can also lock the moisture in the fish meat to prevent loss. While cooling the fish body, the fish meat remains fresh and tender, and the pickled flavor is retained. It does not affect the production efficiency and is also conducive to ensuring the deliciousness of the large yellow croaker frozen products.
[0035] In an optional embodiment, it also includes a freezing box 5, a chain conveyor belt 6, a liquid freezing pool 7 and a vacuum freezing chamber 8. The platform 1 is arranged in the freezing box 5, the vertical conveyor belt group 13 is connected to the liquid freezing pool 7 through a chain conveyor belt 6, and the liquid freezing pool 7 is connected to the vacuum freezing chamber 8 through another chain conveyor belt 6.
[0036] From the above description, it can be seen that after being drained and preliminarily frozen, the large yellow croaker is then passed through the liquid freezing pool 7 and the vacuum freezing chamber 8 for double freezing, which is beneficial to protecting the quality of the fish, retaining the nutrition and improving the flavor of the fish.
[0037] Please refer to Figures 1 to 4 As shown, the first embodiment of the present invention is: a freezing system for producing frozen large yellow croaker, comprising: The platform 1 is provided with more than three limiting upright plates 11 at intervals, the limiting upright plates 11 are parallel to each other, a locking hole group for installing the limiting upright plates 11 is provided on the platform 1, a conveying channel 12 is provided between two adjacent limiting upright plates 11, and the width of the conveying channel 12 can be adjusted when the limiting upright plates 11 are locked with different locking holes in the locking hole group to meet the processing requirements of fish bodies of different sizes, and a vertical conveyor belt group 13 is provided in the conveying channel 12, and the vertical conveyor belt group 13 is used to clamp and convey large yellow croaker; The guide column 2 is slidably arranged on the platform 1 through a sliding seat. The vertical conveyor belt group 13 is sent out from one conveying channel 12 and then turns through the guide column 2 to enter another adjacent conveying channel 12; the guide column 2 is detachably connected to the sliding seat, and the conveying requirements of large yellow croakers of different sizes can be adapted by replacing the guide column 2; with the rotating shaft of the guide column as the center of the circle, the angle range formed with the two adjacent conveying channels under normal conditions is 30°~60°; The elastic member 3 is connected to the platform 1 and the guide column 2, respectively, and is used to support the guide column 2 in a direction away from the limiting vertical plate 11. In this embodiment, the elastic member 3 is a spring, and the specification of the spring can be selected according to the processing requirements of fish bodies of different sizes. The elastic force of the spring is negatively correlated with the size of the fish body, thereby preventing the large yellow croaker from being damaged when passing through the guide column 2.
[0038] The vertical conveyor belt group 13 includes two synchronously moving vertical conveyor belts 131, each of which is continuously conveyed forward by the drive of the conveying motor set on the platform 1 and the guidance of the guide roller group. The surface of the vertical conveyor belt 131 is provided with a drain hole, and the drain hole is preferably a strip hole, so as to quickly and comprehensively drain the liquid. The side wall of the limiting vertical plate 11 is provided with a rotating column 111 for limiting the vertical conveyor belt 131, and the rotating column 111 is preferably a rubber roller. The platform 1 is provided with a through groove at the position corresponding to the conveying channel 12. The cross section of the through groove is designed to be conical or arc-shaped, which can support and limit the body of the large yellow croaker. The bottom of the through groove is provided with a strip-shaped drain port 14, and the drain port 14 is connected to the water receiving tank below the platform 1. The surface of the guide column 2 is provided with an arc groove 21 along the circumferential direction. The curvature of the arc groove 21 is positively correlated with the size of the fish body, so as to avoid the large yellow croaker from damaging the fish meat when passing through the guide column 2. The surface of the arc groove 21 is provided with an annular rubber layer, and the annular rubber layer can be designed with convex edges, which can increase friction to assist the fish body to pass smoothly on the one hand, and squeeze the fish body to further drain impurities on the other hand. Two adjacent limiting vertical plates 11 are respectively provided with staggered arc bosses 112 on two oppositely arranged surfaces. An air cooler 4 and an ultraviolet disinfection lamp are arranged above the platform 1, and the air cooler 4 is provided with an air outlet arranged toward the conveying channel 12. It also includes a freezer 5, a chain plate conveyor belt 6, a liquid freezing pool 7 and a vacuum freezing chamber 8. The platform 1 is arranged in the freezer 5, and the vertical conveyor belt group 13 is connected to the liquid freezing pool 7 through a chain plate conveyor belt 6. The liquid freezing pool 7 contains a freezing medium (-40℃~-35℃), including glycerin, sodium amide, ethanol, etc. The liquid freezing pool 7 is connected to the vacuum freezing chamber 8 through another chain plate conveyor belt 6.
[0039] In summary, the freezing system for producing frozen large yellow croaker of the present invention is designed as a platform specially used for conveying large yellow croaker, and a limiting vertical plate and a guide column are arranged on the platform. The vertical conveyor belt group can clamp the large yellow croaker, and the limiting vertical plate forms a conveying channel. The guide column has a steering and traction function, so that the vertical conveyor belt group conveys the large yellow croaker along an S-shaped route on the platform. The large yellow croaker is drained in a straight conveying section, and the vertical conveyor belt group passes around the guide column. Under the action of the elastic member, the guide column has a tendency to move away from the limiting vertical plate. When the large yellow croaker passes through the first guide column along the vertical conveyor belt, the guide column compresses the spring and slides on the platform, so that the large yellow croaker can be more adaptively adjusted according to the size of the large yellow croaker. The size of the angle formed by the guide column and the two adjacent conveying channels is such that small fish match a larger angle and large fish match a smaller angle, so as to ensure the drainage effect while avoiding excessive squeezing and damaging the fish meat. The body of the yellow croaker bends in one direction along with the vertical conveyor belt group, so that the processing liquid and mucus remaining in the fish body and fish belly are squeezed out. After that, when the yellow croaker is conveyed by the vertical conveyor belt through the second guide column, the body of the yellow croaker bends in the opposite direction along with the vertical conveyor belt group to further drain out the residual liquid. In this way, the excess liquid impurities of the pickled yellow croaker can be fully removed before freezing and packaging, so as to avoid the fishy smell of the yellow croaker product when it is eaten later, thereby improving the quality of the product.
