Description

Technical Field

[0001] This utility model relates to the field of bread processing equipment technology, and more specifically, to a lifting-type non-destructive cooling line for bread. Background Technology

[0002] Because bread reaches excessively high temperatures after baking and shaping, it cannot be directly packaged, making cooling crucial. Traditionally, bread is placed on a conveyor belt, where it cools naturally during transport or is transferred to a refrigeration chamber for further cooling.

[0003] A search revealed that existing patent publication number CN219330571U discloses a multi-strip bread cooling conveyor device, including a conveying mechanism and a cooling mechanism. The conveying mechanism includes a concave conveyor frame and a conveyor mesh plate. Conveyor rollers are rotatably connected to both ends of the concave conveyor frame along its length, and a conveyor mesh plate is wound between the two conveyor rollers. The cooling mechanism includes an inverted concave cooling hood and a suction pipe. The inverted concave cooling hood is snapped onto the upper surface of the concave conveyor frame, and its outer wall is fixed to the outer wall of the concave conveyor frame by fixing bolts. In this utility model, the multi-strip bread cooling conveyor device combines the cooling mechanism with the conveying mechanism, allowing the bread to be cooled during conveying, thereby reducing the overall footprint of the cooling and conveying mechanisms and improving bread processing efficiency. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] Existing bread cooling conveyor systems suffer from problems because bread contains a lot of moisture and air. After baking, the bread is hot and has a relatively soft structure. During the conveying process, the large heat contact area at the bottom of the bread prevents heat from dissipating in time, causing the dough at the bottom to continue to expand while the rest of the bread has already set. Furthermore, because the bread is still soft during cooling, it needs to be placed on the conveyor belt during transport, which causes the bottom of the bread to bulge and deform, thus damaging the overall shape of the bread.

[0005] Therefore, a non-destructive bread cooling line with a lifting mechanism is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a non-destructive cooling line for bread lifting to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a lifting-type bread cooling line without damage, comprising a load-bearing bracket, a hollow conveyor frame, an air duct, and a ventilation silicone bracket. Both ends of the inner cavity of the load-bearing bracket are equipped with drive rollers. The outer surfaces of both ends of the drive rollers are provided with toothed grooves. A belt is fitted onto the outer surface of every two sets of toothed grooves. The hollow conveyor frame is fixedly connected to the opposite surfaces of the two sets of belts. Several sets of hollow conveyor frames are provided, and a motor is installed on the right side of the front end of one set of the load-bearing bracket.

[0008] Fixed plates are provided at the center of the front and rear ends of the load-bearing bracket. Fans are installed on both sides of the bottom of the fixed plates. Air supply pipes are installed on the opposite sides of the two sets of fixed plates. Air outlet nozzles are opened on the outer surface of the air supply pipes. A silicone tray is installed at the upper end of the hollow conveyor frame. The ventilation silicone bracket is opened on the inner surface of the silicone tray.

[0009] Preferably, several sets of the hollow conveyor frames are distributed at equal intervals, and the motor is used to drive one set of the transmission rollers to rotate around its axis.

[0010] Preferably, the two sets of belts are symmetrically arranged, and the teeth on the inner surface of the belts are engaged with the teeth on the outer surface of the tooth grooves.

[0011] Preferably, when the belt rotates with the drive roller, the belt drives the hollow conveyor frame to rotate through the tooth groove.

[0012] Preferably, the silicone trays are provided in several groups, and the ventilated silicone supports are in the shape of several strips and are distributed at equal intervals.

[0013] Preferably, the air supply pipe and the air outlet nozzle are provided in several groups, and the output end of the fan in each group is connected to one of the groups of air supply pipes.

[0014] Preferably, the several groups of air supply pipes and the several groups of air outlet nozzles are distributed at equal intervals, and a short pipe is provided between every three groups of air supply pipes, and the three groups of air supply pipes are interconnected through the short pipes.

[0015] Preferably, the silicone trays are arranged adjacent to each other in every two sets, and the edges of the silicone trays are inclined upward at 20°.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. Compared with existing technologies, this lifting-type bread cooling line adopts a hollow ventilation structure through the conveyor hollow frame, and the silicone tray has ventilation silicone support, which allows air to circulate more smoothly at the bottom of the bread, so that the bottom of the bread and other parts can get the same cooling effect, effectively preventing the bread from shrinking, deforming or collapsing during the cooling process.

[0018] 2. Compared with existing technologies, this lifting-type bread cooling line uses a silicone tray to lift the bread. The bread is relatively soft during the cooling process and is easily deformed or damaged by squeezing and collision. The silicone tray provides good cushioning when in contact with the bread, which can effectively reduce the damage caused by vibration and collision during the conveying process, prevent the bread from deforming, and protect the appearance and integrity of the bread.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] As attached Figures 1 to 4The bread-lifting, non-destructive cooling line shown includes a load-bearing bracket 1, a hollow conveyor frame 5, an air duct 9, and a ventilation silicone bracket 13. The load-bearing bracket 1 provides support for the entire cooling line. Drive rollers 2 are installed at both ends of the inner cavity of the load-bearing bracket 1, providing rotational power. Toothed grooves 3 are formed on the outer surfaces of both ends of the drive rollers 2, providing meshing power to the belts 4. A belt 4 is fitted onto the outer surface of every two sets of toothed grooves 3. The belts 4 serve as the power transmission medium for the hollow conveyor frame 5, driving it to move cyclically, thereby conveying bread through the cooling line. Simultaneously, it also has a certain... The flexible hollow conveyor frame 5 is fixedly connected to the opposite sides of the two sets of belts 4. Several sets of hollow conveyor frames 5 are provided. The hollow conveyor frames 5 are used to carry the silicone tray 12 and bread. Multiple hollow conveyor frames 5 are connected together to form a continuous conveying channel, which allows the bread to move smoothly on it and realizes the continuous conveying of bread on the cooling line. Its hollow structure facilitates ventilation, etc. A motor 6 is installed on the right side of the front end of one set of load-bearing brackets 1. The motor 6 serves as the power source of the entire cooling line and provides power for the rotation of the transmission roller 2. By controlling the speed of the motor 6, the running speed of the belt 4 and the hollow conveyor frame 5 can be precisely adjusted.

[0027] Fixed plates 7 are installed at the center of both the front and rear ends of the load-bearing bracket 1. The fixed plates 7 fix the fan 8 and the air supply pipe 9, providing a stable installation position for the fan 8 and the air supply pipe 9. Fans 8 are installed on both sides of the bottom of the fixed plates 7, and air supply pipes 9 are installed on the opposite sides of the two sets of fixed plates 7. The air supply pipes 9 deliver the cooling air generated by the fans 8 to the air outlet nozzles 11. The air outlet nozzles 11 on the outer surface of the air supply pipes 9 can evenly distribute the cooling air, so that the cooling air can be accurately and evenly blown to the bottom of the bread, ensuring that all parts of the bottom of the bread are fully cooled, and achieving a uniform cooling effect. The air outlet nozzles 11 are opened on the outer surface of the air supply pipes 9, and the air outlet nozzles 11 deliver the cooling air... The cooling air is sprayed at a suitable angle and speed, precisely guiding it to the bottom of the bread to ensure that the bread is cooled evenly and effectively. A silicone tray 12 is installed at the upper end of the hollow conveyor frame 5. The silicone tray 12 is used to support the bread. Its soft silicone material can fit well with the surface of the bread, providing cushioning protection and preventing the bread from being damaged during conveying. A ventilated silicone support 13 is opened on the inner surface of the silicone tray 12. The ventilated silicone support 13 further enhances the ventilation performance of the silicone tray 12, allowing the cooling air to better reach the bottom of the bread through the silicone tray 12, promoting air circulation, improving the cooling effect, and also providing support and protection.

[0028] Example 2

[0029] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0030] In a preferred embodiment, several sets of hollow conveyor frames 5 are distributed at equal intervals. The equal-interval hollow conveyor frames 5 allow each loaf of bread to pass through the cooling zone under the same cooling conditions, resulting in more uniform cooling. A motor 6 drives one set of transmission rollers 2 to rotate around its axis. As a power source, the motor 6 provides stable and continuous power to the entire conveying system. Two sets of belts 4 are symmetrically arranged. The teeth on the inner surface of the belts 4 mesh with the teeth on the outer surface of the tooth grooves 3. When the belts 4 rotate with the transmission rollers 2, they drive the hollow conveyor frames 5 to rotate through the tooth grooves 3. The two sets of symmetrically arranged belts 4 can provide uniform support force to the hollow conveyor frames 5, keeping them balanced and stable during operation and preventing tilting or shaking. This ensures that the bread passes smoothly through the cooling line. The meshing of the teeth on the inner surface of the belts 4 with the teeth on the outer surface of the tooth grooves 3 accurately transmits the power of the transmission rollers 2 to the belts 4, thereby driving the hollow conveyor frames 5 to move.

[0031] In a preferred embodiment, the silicone trays 12 are provided in several groups, and the ventilated silicone supports 13 are in the shape of several strips and are evenly distributed. Multiple silicone trays 12 can carry multiple loaves of bread for transport at the same time, increasing the number of loaves that the cooling line can process at the same time and greatly improving the efficiency of bread cooling. The evenly distributed strip-shaped ventilated silicone supports 13 form many ventilation channels on the silicone trays 12, allowing the cooling air to smoothly reach the bread through the bottom of the tray, increasing the contact area between the bread and the cold air, promoting air convection, and accelerating the cooling process of the bread. The strip-shaped ventilated silicone supports 13 not only play a ventilation role, but also provide a certain support for the silicone trays 12. The silicone is soft and its surface is relatively smooth. When in contact with the bread surface, the friction is small, which can prevent the bread crust from being scratched by the rough surface of the tray or other parts during the bread cooling and transport process.

[0032] In a preferred embodiment, several sets of air supply pipes 9 and air outlet nozzles 11 are provided. The output end of each set of fans 8 is connected to one set of air supply pipes 9. The several sets of air supply pipes 9 and several sets of air outlet nozzles 11 are distributed at equal intervals. Multiple air outlet nozzles 11 can disperse the cooling air to different positions on the bottom of the bread, so that the bread can be evenly contacted by the cooling air and avoid local overheating or overcooling. A short pipe 10 is provided between every four sets of air supply pipes 9. Every four sets of air supply pipes 9 are interconnected through the short pipe 10. The connection of the short pipe 10 can connect the four adjacent sets of air supply pipes 9, ensuring that each set of air supply pipes 9 and air outlet nozzles 11 can provide stable and uniform cooling air.

[0033] In a preferred embodiment, each pair of silicone trays 12 are arranged adjacent to each other, with the edges of the silicone trays 12 tilted upwards at 20°. The adjacent arrangement allows the silicone trays 12 to be arranged closely, maximizing the number of trays on the limited hollow conveyor frame 5, thereby increasing the bread conveying capacity and improving the working efficiency per unit length of the cooling line. The tilted edges of the silicone trays 12 can form a barrier, which limits the bread placed on the silicone trays 12, especially when the bread moves with the tray, turns, or encounters some minor vibrations, effectively preventing the bread from slipping off the edge of the tray.

[0034] The working process of this utility model is as follows: First, the motor 6 starts and drives one of the transmission rollers 2 to rotate around its axis as a power source. The tooth grooves 3 on the outer surface of both ends of the transmission roller 2 mesh with the teeth on the inner surface of the belt 4. When the transmission roller 2 rotates, it drives the belt 4 to move. Since the two sets of belts 4 are symmetrically arranged and mesh with the tooth grooves 3, the belt 4 can accurately transmit the power of the transmission roller 2 and drive the hollow conveyor frame 5, which is fixedly connected to the opposite side of the two sets of belts 4, to rotate, so that the hollow conveyor frame 5 moves in a cycle to form a continuous conveying channel.

[0035] Subsequently, the bread is placed on the silicone tray 12 at the top of the hollow conveyor frame 5. The soft material of the silicone tray 12 conforms well to the surface of the bread, providing cushioning and protection. Several groups of silicone trays 12, evenly spaced and adjacent to each other, are closely arranged on the hollow conveyor frame 5, capable of holding multiple loaves of bread simultaneously. Ventilated silicone supports 13 are distributed in evenly spaced strips on the inner surface of the silicone tray 12, forming ventilation channels. This allows cooling air to better penetrate the silicone tray 12 and reach the bottom of the bread, increasing the contact area between the bread and the cold air, promoting air convection, and accelerating the cooling process. The edges of the silicone tray 12 are tilted upwards at 20°, forming a barrier to limit the movement of the bread and prevent it from shifting during transport. As the bread slides down the conveyor hollow frame 5, it is continuously conveyed on the cooling line. The fixed plate 7 fixes the fan 8 and the air supply pipe 9. After the fan 8 is started, it generates cooling air, which is conveyed through the air supply pipe 9. Several sets of air supply pipes 9 and air outlet nozzles 11 are evenly distributed. Multiple air outlet nozzles 11 disperse the cooling air to different positions on the bottom of the bread. At the same time, every four sets of air supply pipes 9 are interconnected by short pipes 10 to ensure that each set of air supply pipes 9 and air outlet nozzles 11 can provide stable and uniform cooling air, so that the cooling air is evenly blown to the bottom of the bread, achieving uniform cooling of the bread. After cooling, the bread enters the subsequent stage for processing. The above is the working principle of this kind of lifting bread non-destructive cooling line.
