Description

Technical Field

[0001] This utility model relates to the technical field of soybean product production equipment, and in particular to an automatic cooling device for producing tofu sheets. Background Technology

[0002] Thousand-layer tofu is made by pressing and slicing soy milk into multiple layers after coagulation. It has a moderate thickness, distinct layers, and strong toughness. In the production process of stamped tofu, the formed thousand-layer tofu is at a high temperature after the previous process, so it needs to be cooled before packaging. The traditional cooling method is to spread it out to cool. However, due to the trend of automation in production, automated workshops do not have the space required to spread out a large number of thousand-layer tofu for cooling. Therefore, an automated conveyor belt with a fan is used to blow cool air on the thousand-layer tofu while it is being transported. However, due to the small area of ​​the spread-out tofu and the small intervals between the thousand-layer tofu during transport, the blowing effect of the fan next to the conveyor belt is not good, and it can only achieve localized cooling, resulting in poor cooling effect. To achieve better results, the speed of the conveyor belt must be slowed down and the blowing time increased for more comprehensive cooling. However, this will affect the production efficiency. Therefore, it is necessary to continue to improve the existing cooling conveyor equipment to improve its cooling efficiency and operating speed to solve the above problems. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides an automatic cooling device for the production of tofu sheets, comprising a suspended conveying mechanism and a cooling device. The cooling device is mounted on a mounting frame of the suspended conveying mechanism and communicates with the interior of the mounting frame. The cooling device includes a cooling fan, a mounting cavity, an air outlet pipe, and a pair of air outlet branch pipes. The cooling fan is located on one side of the mounting frame, which has an air inlet. The mounting cavity is located within the air inlet. The air outlet pipe is located on the mounting cavity, with one end connected to the air outlet of the cooling fan and the other end connected to the pair of air outlet branch pipes. The pair of air outlet branch pipes are symmetrically arranged inside the mounting frame, each with several small air holes and an airflow control structure.

[0004] By adopting the above technical solution, a cooling device including a cooling fan, mounting cavity, air outlet duct, and a pair of air outlet branch ducts is installed on the mounting frame of the suspended conveyor mechanism. An air volume control mechanism is then installed on the pair of air outlet branch ducts. Cold air with better cooling effect replaces ordinary fan blowing, effectively improving the cooling effect. A pair of air outlet branch ducts are installed at the end of the air outlet duct, and several small air holes are set on the air outlet branch ducts so that the cold air from the air cooler can be discharged through the small air holes of the air outlet branch ducts. This allows the cold air to cover a large area of ​​tofu sheets on the suspended conveyor mechanism. Even when the tofu sheets are moving, they can still be aligned and continuously cooled by cold air, further improving the cooling effect. This allows the tofu sheets to cool down quickly, while also ensuring the operating speed of the conveyor mechanism.

[0005] Further features of this invention: The air volume control structure includes a connecting pipe and several inclined air outlet pipes. Each pair of air outlet branch pipes includes a fast air outlet pipe and a slow air outlet pipe. The diameter of the small air holes on the slow air outlet pipe is larger than the diameter of the small air holes on the fast air outlet pipe. A connecting hole is opened on the upper part of the slow air outlet pipe. The two ends of the connecting pipe are respectively connected to the connecting hole and the small air holes at the end of the fast air outlet pipe. The several inclined air outlet pipes are arranged on the several small air holes of the fast air outlet pipe.

[0006] Using the above technical solution, the airflow control structure includes a connecting pipe and several inclined air outlet pipes. Each pair of air outlet branch pipes includes a fast air outlet pipe and a slow air outlet pipe. The diameter of the small air holes on the slow air outlet pipe is larger than the diameter of the small air holes on the fast air outlet pipe. A connecting hole is opened at the upper part of the slow air outlet pipe. The two ends of the connecting pipe are respectively connected to the connecting hole and the small air holes at the end of the fast air outlet pipe. The several inclined air outlet pipes are arranged on the several small air holes of the fast air outlet pipe. The small air holes are controlled by setting small air holes of different diameters on the fast air outlet pipe and the slow air outlet pipe. The wind speed is controlled by installing oblique air outlets on several small air holes in the fast air duct, so that the air coming out of the fast air duct can blow obliquely onto the tofu sheets on the suspended conveyor mechanism. This avoids the situation where adjacent tofu sheets stick together due to the influence of the fast airflow caused by excessive vertical airflow. In this way, most of the heat of the tofu sheets can be removed by the high-speed cold air. After passing through the fast air duct, the tofu sheets are then cooled by vertical airflow at a normal flow rate through the slow air duct, removing the remaining heat. This efficiently completes the cooling process of the tofu sheets.

[0007] A further feature of this invention is that an anti-fall conveyor belt is provided on the suspended conveyor mechanism near the bottom of the mounting frame.

[0008] By adopting the above technical solution, since the suspended conveyor mechanism is equipped with an anti-fall conveyor belt located near the bottom of the mounting frame, the situation of the tofu sheets being accidentally blown off during the cooling process can be avoided.

[0009] A further feature of this invention is that an operating port is provided on one side of the mounting cavity, and a detachable door panel is provided on the operating port.

[0010] By adopting the above technical solution, since an operating port is provided on one side of the installation cavity and a detachable door panel is provided on the operating port, it is convenient to adjust and maintain the air outlet branch pipe. Attached Figure Description

Detailed Implementation

[0015] like Figure 1-3 As shown, an automatic cooling device for producing tofu sheets includes a suspended conveying mechanism 1 and a cooling device 2. The cooling device is mounted on a mounting frame 15 of the suspended conveying mechanism and communicates with the interior of the mounting frame. The cooling device includes a cooling fan 3, a mounting cavity 4, an air outlet pipe 5, and a pair of air outlet branch pipes 6. The cooling fan is located on one side of the mounting frame, and the mounting frame has an air inlet. The mounting cavity is located inside the air inlet. The air outlet pipe is located on the mounting cavity. One end of the air outlet pipe is connected to the air outlet of the cooling fan, and the other end is connected to the pair of air outlet branch pipes. The pair of air outlet branch pipes are symmetrically arranged inside the mounting frame. Each pair of air outlet branch pipes has several small air holes 7 and an air volume control structure 8.

[0016] By installing a cooling device including a cooling fan, mounting cavity, air outlet duct, and a pair of air outlet branch ducts on the mounting frame of the suspended conveyor mechanism, and then installing an airflow control mechanism on the pair of air outlet branch ducts, the cooling effect is effectively improved by replacing ordinary fans with cold air that has a better cooling effect. A pair of air outlet branch ducts are installed at the end of the air outlet duct, and several small air holes are set on the air outlet branch ducts so that the cold air from the air cooler can be discharged through the small air holes of the air outlet branch ducts. This allows the cold air to cover a large area of ​​the tofu sheets 16 on the suspended conveyor mechanism. Even when the tofu sheets are moving, they can still be aligned and continuously cooled by cold air, further improving the cooling effect and allowing the tofu sheets to cool down quickly, while also ensuring the operating speed of the conveyor mechanism.

[0017] The air volume control structure includes a connecting pipe 9 and several outlet oblique pipes 10. Each pair of outlet branch pipes includes a fast air pipe 11 and a slow air pipe 12. The diameter of the small air holes on the slow air pipe is larger than the diameter of the small air holes on the fast air pipe. A connecting hole is opened on the upper part of the slow air pipe. The two ends of the connecting pipe are respectively connected to the connecting hole and the small air holes at the end of the fast air pipe. The several outlet oblique pipes are arranged on the several small air holes of the fast air pipe.

[0018] The airflow control structure includes a connecting pipe and several inclined air outlet pipes. Each pair of air outlet branch pipes includes a fast air outlet pipe and a slow air outlet pipe. The diameter of the small air holes on the slow air outlet pipe is larger than that on the fast air outlet pipe. A connecting hole is opened on the upper part of the slow air outlet pipe. The two ends of the connecting pipe are connected to the connecting hole and the small air holes at the end of the fast air outlet pipe, respectively. Several inclined air outlet pipes are set on several small air holes of the fast air outlet pipe. By setting small air holes of different diameters on the fast air outlet pipe and the slow air outlet pipe, the air speed of the small air holes is controlled. By setting the inclined air outlet pipes on several small air holes of the fast air outlet pipe, the air from the fast air outlet pipe can blow obliquely onto the tofu sheets on the suspended conveyor mechanism, avoiding the situation where adjacent tofu sheets stick together due to the influence of the fast airflow due to the excessive vertical airflow speed. Thus, most of the heat of the tofu sheets can be removed by the high-speed cold air. After passing through the fast air outlet pipe, the slow air outlet pipe will then carry out vertical airflow at a normal flow rate to cool the tofu sheets and remove the remaining heat, thereby efficiently completing the cooling process of the tofu sheets.

[0019] The suspended conveyor mechanism is equipped with a fall-proof conveyor belt 13 located near the bottom of the mounting frame.

[0020] Because the suspended conveyor mechanism is equipped with an anti-fall conveyor belt located near the bottom of the mounting frame, the tofu sheets can be prevented from being accidentally blown off during the cooling process.

[0021] The mounting cavity has an operating port on one side and a detachable door panel 14 on the operating port.

[0022] Since the installation cavity has an operating port on one side and a detachable door panel on the operating port, it is convenient to adjust and maintain the air outlet branch pipe.
