Abstract
Description
Technical Field
[0001] This utility model relates to the field of sunflower seed processing technology, specifically a rapid cooling device for sunflower seed processing. Background Technology
[0002] In the production process of sunflower seeds, the cooling stage is crucial. Conventional sunflower seed production generally involves multiple steps, including screening, soaking and flavoring, steaming, drying, cooling, and packaging. The traditional cooling method involves pouring the processed seeds onto a clean surface to cool naturally, and then collecting them manually after cooling. This method is not only inefficient and labor-intensive, but also allows the seeds to easily accumulate dust and other impurities during prolonged exposure, affecting their taste.
[0003] To improve the cooling efficiency of sunflower seeds and shorten the production cycle, some processing companies have adopted the method of placing air coolers on the conveyor belt to cool the seeds. While this method speeds up the cooling process to some extent, it has also caused a series of new problems. First, when the sunflower seeds are conveyed on the conveyor belt, the air coolers blow cold air from above, which only temporarily cools the surface of the seeds and cannot cool the bottom, resulting in low cooling efficiency. Second, because dried sunflower seeds are relatively light, if the airflow is too weak, it is difficult to ensure the cooling quality. To achieve the ideal effect, multiple fans are often required, which undoubtedly increases production costs significantly. On the other hand, if the airflow is too strong, it is easy to blow the sunflower seeds off the conveyor belt, disrupting the normal conveying rhythm and seriously affecting the automated production process of sunflower seeds. Utility Model Content
[0004] Therefore, to address the aforementioned shortcomings, this utility model provides a rapid cooling device for sunflower seed processing. This cooling device cools sunflower seeds by combining an air-cooled conveying mechanism and a vibrating cooling frame with a refrigerant coil. The refrigerant flowing inside the refrigerant coil cools the air outside the coil, and the vibration of the cooling frame throws the sunflower seeds upwards, ensuring that both sides of the seeds come into contact with the outside of the coil. This achieves multi-stage cooling of the sunflower seeds, effectively improving the cooling efficiency. Furthermore, it allows for continuous conveying of the seeds, enabling automated cooling. Compared to traditional air cooling, this device avoids the problem of sunflower seeds being blown out by the wind and also avoids the increased cost of having multiple fans. This device is low-cost, easy to install and use, and readily adopted.
[0005] This utility model is implemented as follows: a rapid cooling device for sunflower seed processing is provided, including a cooling frame placed on a base and driven by a vibration motor to vibrate;
[0006] A baffle plate is movably mounted on the feeding end of the cooling frame to ensure that the sunflower seeds move evenly within the cooling frame.
[0007] The refrigerant coil is fixed to the inner bottom of the cooling frame and maintains a gap between it and the inner bottom. The vibration of the cooling frame causes the sunflower seeds to shake upwards and keep them in contact with the refrigerant coil for cooling.
[0008] The air-cooled conveying mechanism is located above the feed end of the cooling frame to air-cool the sunflower seeds.
[0009] Preferably, an elastic element is installed on the outer side of the cooling frame via a mounting block, and the cooling frame is elastically connected to the base via the elastic element.
[0010] Preferably, the inner bottom of the cooling frame is a slope, and its feed end is located at the highest position of the slope. The vibration motor is mounted above the cooling frame through a bracket. One end of the refrigerant coil extends through to the outer end of the cooling frame and is connected to an external hose, while the other end is arranged along the length of the inner bottom of the cooling frame.
[0011] Preferably, the refrigerant coil is fixed to the inner bottom of the cooling frame by several pipe clamps, so that there is a gap between the refrigerant coil and the inner bottom of the cooling frame.
[0012] Preferably, the side of the cooling frame has a strip-shaped hole in the vertical direction, and the baffle plate is set inside the cooling frame and fixed by fastening bolts passing through the strip-shaped hole and engaging with nuts.
[0013] Preferably, the end of the baffle plate is provided with a threaded connection hole, one end of the fastening bolt is provided with a first thread for inserting into the threaded connection hole, and the other end of the fastening bolt is provided with a second thread for engaging with the nut.
[0014] Preferably, the end of the baffle plate has at least two threaded connection holes, and each threaded connection hole is fitted with a fastening bolt and a nut.
[0015] Preferably, the air-cooled conveying mechanism includes a conveyor belt 18 disposed in the cavity 13. The conveyor belt 18 is tensioned in the cavity 13 and keeps rotating. A feed inlet 14 is provided at the top of one side of the cavity 13. A negative pressure exhaust pipe 16 and a discharge port 17 are respectively provided at the top and bottom of the other side of the cavity 13. The discharge port 17 corresponds to the feed end of the cooling frame. A cold air blower 15 for blowing cold air onto the conveyor belt 18 is also provided at the top of the cavity 13.
[0016] Preferably, the conveyor belt 18 is a chain plate conveyor belt or a mesh belt, and baffles 19 are provided on both sides of the conveyor belt 18.
[0017] Compared with the prior art, the present invention has the following advantages:
[0018] 1. This cooling device cools sunflower seeds by combining an air-cooled conveying mechanism and a vibrating cooling frame with a refrigerant coil. The refrigerant flowing inside the refrigerant coil cools the air outside the coil. The vibration of the cooling frame throws the sunflower seeds upward, allowing both sides of the seeds to contact the outside of the coil. This achieves multi-stage cooling of the sunflower seeds, effectively improving the cooling efficiency. Furthermore, it allows for continuous conveying of the sunflower seeds, enabling automated cooling.
[0019] 2. Unlike traditional air-cooling methods, this device combines air cooling with refrigerant cooling, eliminating the risk of excessive airflow blowing the sunflower seeds out. This ensures the sunflower seeds remain stably within the cooling frame throughout the cooling process, guaranteeing the continuity and stability of the production flow. It also prevents problems such as conveyor interruptions and material losses caused by sunflower seeds being blown out, effectively guaranteeing the smooth operation of automated sunflower seed production.

[0034] As described in the background section, sunflower seed production enterprises currently generally use air-cooled conveyor belts to quickly cool sunflower seeds. However, this method can only cool the top surface of the seeds, which is not efficient enough. Furthermore, the air-cooling process may cause sunflower seeds to be blown off the conveyor belt, affecting the conveying process.
[0035] Based on the above reasons, in order to solve the above problems, this utility model provides the following technical solution:
[0036] Example 1,
[0037] Please see the appendix Figure 1 ~Appendix Figure 2 A rapid cooling device for processing sunflower seeds includes a cooling frame 2, which is placed on a base 1 and vibrated by a vibration motor 6.
[0038] The baffle plate 9 is movably set on the feeding end of the cooling frame 2 to make the sunflower seeds move evenly within the cooling frame 2;
[0039] The cooling medium coil 7 is fixed to the inner bottom of the cooling frame 2 and maintains a gap between it and the inner bottom. The vibration of the cooling frame 2 causes the sunflower seeds to shake upwards and keep them in contact with the cooling medium coil 7 for cooling.
[0040] The air-cooled conveying mechanism is located above the feed end of the cooling frame 2 to air-cool the sunflower seeds.
[0041] In this embodiment, to facilitate the conveying of sunflower seeds and to facilitate cooling of the seeds during conveying, the inner bottom of the cooling frame 2 is inclined, and its feeding end is set at the highest position of the inclined surface. The vibration motor 6 is installed above the cooling frame 2 through the bracket 5. One end of the cooling medium coil 7 extends through to the outer end of the cooling frame 2 and is connected to the external hose, while the other end is arranged along the length direction of the inner bottom of the cooling frame 2.
[0042] In practical use, refrigerant is first introduced into the refrigerant coil 7 through an external hose and an external refrigeration system to maintain circulation and cool the air inside the cooling frame 2. Then, the air-cooled conveying mechanism is started to convey and air-cool the sunflower seeds. At the same time, the vibration motor 6 is started to drive the cooling frame 2 to vibrate. The air-cooled conveying mechanism conveys the sunflower seeds cooled on the upper surface to the feeding end of the cooling frame 2. Under the vibration of the baffle plate 9 and the cooling frame 2, the sunflower seeds flow evenly to the lower end of the slope and are thrown upwards to contact the refrigerant coil 7 for heat exchange, thus achieving overall cooling of the sunflower seeds. Finally, the sunflower seeds are discharged from the lowest point of the cooling frame 2, completing the cooling process.
[0043] Example 2,
[0044] Please see the appendix Figure 3 and attached Figure 4 Based on Embodiment 1, in order to ensure that the cooling frame can vibrate on the base, an elastic element 4 is installed on the outside of the cooling frame 2 through the mounting block 3, and the cooling frame 2 is elastically connected to the base 1 through the elastic element 4.
[0045] Example 3,
[0046] Please see the appendix Figure 5 Based on Embodiment 1, in order to ensure that the sunflower seeds can move within the cooling frame while ensuring the fixation of the cooling medium coil, the cooling medium coil 7 is fixed to the inner bottom of the cooling frame 2 by several pipe clamps 8, so that there is a gap between the cooling medium coil 7 and the inner bottom of the cooling frame 2, which facilitates the movement of the sunflower seeds on the cooling frame 2.
[0047] Example 4,
[0048] Please see the appendix Figure 4 and attached Figure 6Based on embodiment 1, in order to ensure that the sunflower seeds move evenly in the cooling frame and thus facilitate cooling, the side of the cooling frame 2 is provided with a strip hole 12 in the vertical direction. The baffle plate 9 is set inside the cooling frame 2 and is fixed by fastening bolts 10 passing through the strip hole 12 and connecting with nuts 11.
[0049] In this embodiment, in order to facilitate the installation of the baffle plate inside the cooling frame, the baffle plate 9 has a threaded connection hole at its end, and one end of the fastening bolt 10 has a first thread for inserting into the threaded connection hole, and the other end of the fastening bolt 10 has a second thread for engaging with the nut 11.
[0050] In this embodiment, to prevent the baffle plate from randomly flipping around the connection point of the fastening bolt during vibration, the end of the baffle plate 9 has at least two threaded connection holes, and each threaded connection hole is equipped with a fastening bolt 10 and a nut 11.
[0051] Example 5,
[0052] Please see the appendix Figure 7 Based on the contact in Embodiment 1, in order to facilitate the movement and cooling of sunflower seeds within the cooling frame 2, the cooling medium coil 7 can be replaced with a plate with a cooling medium flow channel. The plate is fixed to the bottom of the cooling frame 2, and its cooling medium flow channel is flexibly connected to the external cooling medium pipeline. When sunflower seeds fall onto the plate, they exchange heat through the cooling medium flowing in the internal cooling medium flow channel, thus achieving cooling and facilitating the movement of the sunflower seeds.
[0053] Example 6,
[0054] Please see the appendix Figure 8 ~Appendix Figure 10 Based on the contact of Embodiment 1, in order to facilitate rapid cooling and uniform conveying of sunflower seeds, an air-cooled conveying mechanism is provided. The air-cooled conveying mechanism includes a conveyor belt 18 disposed in the cavity 13. The conveyor belt 18 is tensioned in the cavity 13 and keeps rotating. A feed inlet 14 is provided at the top of one side of the cavity 13. A negative pressure exhaust pipe 16 and a discharge port 17 are respectively provided at the top and bottom of the other side of the cavity 13. The negative pressure exhaust pipe 16 can be connected to an external negative pressure device to facilitate the discharge of smoke and dust generated during the air cooling of sunflower seeds. The discharge port 17 corresponds to the feed end of the cooling frame. A cold air blower 15 that blows cold air onto the conveyor belt 18 is also provided at the top of the cavity 13.
[0055] In this embodiment, the conveyor belt 18 is a chain plate conveyor belt or a mesh belt, and baffles 19 are provided on both sides of the conveyor belt 18.
[0056] Setting the conveyor belt 18 as a chain plate conveyor belt or mesh belt ensures that the surface of the conveyor belt 18 can withstand the high temperature of the sunflower seeds, while facilitating air flow and cooling of the sunflower seeds. The baffle is set to prevent the sunflower seeds from being blown out when the air cooler is cooling the sunflower seeds on the conveyor belt 18.
[0057] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
