Description

Technical Field

[0001] This utility model relates to the field of food machinery technology, specifically to a discharge mold for a corn puffing machine. Background Technology

[0002] The discharge mold for a corn puffing machine is a key component installed at the end of the puffing machine. Its main function is to extrude corn material that has been treated with high temperature and high pressure through the discharge hole on the mold, so that it expands rapidly during the discharge process to form puffed food with a specific shape and texture. The design and material of the mold directly affect the quality of the product, production efficiency and equipment durability, and it is an important tool for realizing corn puffing processing.

[0003] Existing discharge molds have relatively simple structures, mostly only having the function of discharging material. Since the extruder extrudes multiple corn kernels simultaneously with varying sizes and speeds, the extruded material is prone to unevenness. When this uneven extruded material is squeezed towards the discharge hole, the thicker side of the material may not completely pass through the discharge hole, causing a small portion of the material to accumulate inside, thus clogging the mold. In view of this, we propose a discharge mold for corn extruders. Utility Model Content

[0004] The purpose of this utility model is to provide a discharge mold for a corn puffing machine to solve the problem that when uneven puffed material is squeezed and rushes towards the discharge hole, the thicker side of the material may not pass through completely, and a small part of the material will be stuck and accumulated in the discharge hole, thus causing the mold to be blocked.

[0005] To achieve the above objectives, a discharge mold for a corn puffing machine is provided, including a discharge mold body, wherein the discharge mold body has discharge holes arranged in a ring array and the discharge holes are cone-shaped, and the bottom of the discharge mold body has an installation groove, wherein a cone-shaped guide hopper is provided in the installation groove.

[0006] As a further improvement to this technical solution, the discharge hole is tapered, and the inner wall of the discharge hole is coated with polytetrafluoroethylene.

[0007] As a further improvement to this technical solution, the upper end of the conical guide bucket is provided with a second reserved groove and a first reserved groove, and the second reserved groove and the first reserved groove are arranged vertically.

[0008] As a further improvement to this technical solution, a sealing ring matching its size is installed in the first reserved groove.

[0009] As a further improvement to this technical solution, a first magnetic ring of a size adapted to the second reserved slot is fixedly connected inside the second reserved slot.

[0010] As a further improvement to this technical solution, a second magnetic ring with a magnetic field different from that of the first magnetic ring is fixedly connected to the inner wall of the mounting groove, and the second magnetic ring is in contact with the first magnetic ring.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this corn puffing machine, a conical guide hopper is installed at the bottom of the discharge mold body. When the corn is puffed and discharged near the discharge mold body, it is guided to flow smoothly and orderly to the discharge hole during the puffing process. This effectively reduces the phenomenon of uneven puffing material accumulating in the discharge hole due to disordered puffing. At the same time, the multiple discharge holes are set in a conical shape, making it easier for the puffed corn to pass through and be discharged during the extrusion process, thereby reducing the occurrence of blockage and ensuring the discharge efficiency of the mold.

In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0022] Example 1

[0023] Please see Figures 1-4 As shown, the purpose of this embodiment is to provide a discharge mold for a corn puffing machine, including a discharge mold body 1. The discharge mold body 1 has discharge holes 11 arranged in a ring array, and the discharge holes 11 are cone-shaped. The bottom of the discharge mold body 1 has an installation groove 12, and a cone-shaped guide bucket 2 is provided in the installation groove 12. By setting the installation groove 12, the installation groove 12 provides an installation environment for the cone-shaped guide bucket 2, thereby enhancing the rationality of the structure.

[0024] In addition, the inner wall of the discharge hole 11 is coated with polytetrafluoroethylene. By coating the discharge hole 11 with polytetrafluoroethylene, it has the characteristics of non-stick and low friction, which can further reduce the corn material from clogging in the discharge hole 11.

[0025] Furthermore, the upper end of the conical guide hopper 2 is provided with a second reserved groove 22 and a first reserved groove 21, and the second reserved groove 22 and the first reserved groove 21 are arranged vertically. A sealing ring 23 matching its size is installed in the first reserved groove 21, and a first magnetic ring 24 matching its size is fixedly connected in the second reserved groove 22. A second magnetic ring 25 with a magnetic property different from that of the first magnetic ring 24 is fixedly connected to the inner wall of the mounting groove 12, and the second magnetic ring 25 is in contact with the first magnetic ring 24. After the first magnetic ring 24 and the second magnetic ring 25 are attracted, a sealing ring 23 is formed. The sealing ring 23 ensures that no excessive expanded material enters the mounting groove 12 during the expansion process, preventing the conical guide bucket 2 from not being fully inserted into the mounting groove 12, thus ensuring the use of the conical guide bucket 2. The second reserved groove 22 is at the upper end of the conical guide bucket 2. Therefore, when the conical guide bucket 2 is inserted into the mounting groove 12, the second reserved groove 22 is inside, and the first reserved groove 21 is at the lower end and therefore close to the outside. This arrangement ensures that the sealing ring 23 on the first reserved groove 21 plays a sealing role, ensuring the realization of the function of the sealing ring 23.

[0026] The specific working principle of this solution is as follows: First, the user installs the conical guide bucket 2 into the mounting groove 12 at the bottom of the discharge mold body 1. Since the first magnetic ring 24 and the second magnetic ring 25 have opposite magnetic properties and are in contact, the first magnetic ring 24 on the conical guide bucket 2 and the second magnetic ring 25 on the inner wall of the mounting groove 12 can attract each other. The user can directly insert the conical guide bucket 2 into the mounting groove 12 to complete the assembly of the conical guide bucket 2 and the discharge mold body 1. Then, the conical guide bucket 2 and the discharge mold body 1 are installed together at the discharge port of the corn puffing machine. The discharge hole 11 faces outwards from the discharge port, while the inner side of the conical guide bucket 2 faces inwards from the puffing machine. When the corn puffing machine is started, the corn begins to puff, and the puffed corn travels along the inner side of the conical guide bucket 2. Guided by the conical guide bucket 2, the material begins to exit through the discharge hole 11 on the discharge mold body 1. The design of the conical guide bucket 2 reduces the dead zone in the puffing process, that is, the area where the material flow is not smooth. The existence of the dead zone can easily lead to material retention and blockage. By guiding the flow of puffed corn, the conical guide bucket 2 ensures that a certain amount of puffed material can only flow along the inner wall of the conical guide bucket 2, reducing the formation of the dead zone. When passing through the discharge hole 11, due to the conical setting of the discharge hole 11, its cross-sectional area gradually decreases. According to fluid dynamics, the speed of the puffed corn will gradually increase when passing through the discharge hole 11. This acceleration effect helps to carry the puffed corn out of the discharge hole 11, reducing its accumulation in the discharge hole 11, thereby reducing the possibility of blockage of the discharge hole 11.
