Description

Technical Field

[0001] This utility model belongs to the field of fresh food preservation technology, specifically a vacuum pre-cooling and preservation device for fresh corn. Background Technology

[0002] Fresh corn is a popular agricultural product, and preservation is one of its most important processing methods. Traditional preservation methods mainly rely on low-temperature refrigeration, but this method has many limitations. First, relying solely on low-temperature refrigeration is not enough to quickly lower the temperature of corn in a short period of time, and the pre-cooling process is slow, which may affect the freshness of corn in the initial stage. Second, traditional refrigeration methods cannot effectively control the humidity in the storage environment, which often makes corn in a high-humidity environment. This provides favorable conditions for the growth of microorganisms. At the same time, a high-humidity environment may cause condensation on the surface of corn, further accelerating the reproduction of microorganisms, affecting the appearance and quality of corn, and thus causing corn to spoil, mold, and shorten the shelf life of fresh corn. Utility Model Content

This provides favorable conditions for the growth of microorganisms, accelerates their reproduction, affects the appearance and quality of corn, and leads to spoilage, mold growth, and shortens the shelf life of fresh corn.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vacuum pre-cooling and preservation device for fresh corn, comprising a storage cabinet, a suction mechanism on one side of the storage cabinet, a heating mechanism below the suction mechanism, and a cooling mechanism below the heating mechanism. The suction mechanism includes a fixed frame, which is fixedly connected to one side of the storage cabinet. Several through slots are opened on the side of the fixed frame facing the storage cabinet, and these through slots communicate with the storage cabinet. A suction fan is rotatably connected between the inner walls of the fixed frame. An output motor is fixedly installed at the other end of the fixed frame, and the output end of the output motor is connected to the suction fan. The heating mechanism includes a mounting frame, which is located below the fixed frame and fixedly connected to one side of the storage cabinet. A heating element is fixedly installed inside the mounting frame. The cooling mechanism includes a support frame, which is fixedly connected to the storage cabinet. A cooling element is fixedly installed inside the support frame. A drain outlet is opened at the bottom of the support frame, and several through holes are opened on the side of the support frame facing the storage cabinet, and these through holes communicate with the storage cabinet.

[0006] As a further embodiment of this utility model: the storage cabinet is provided with a storage frame inside, and four limiting blocks are fixedly connected to the four corners of the bottom of the storage frame.

[0007] As a further embodiment of this utility model: four limiting slide rails are fixedly connected to the four corners of the inner wall of the storage cabinet, and the four limiting blocks slide between the inner walls of the four limiting slide rails respectively.

[0008] As a further embodiment of this utility model: the storage cabinet is provided with a vibrating screen mechanism, the vibrating screen mechanism includes a control motor, the control motor is fixedly installed on the outer wall of the storage cabinet, the output end of the control motor passes through one side of the storage cabinet and the end is fixedly connected to a drive arm.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This vacuum pre-cooling and preservation device for fresh corn, by setting up a suction mechanism, a heating mechanism, and a cooling mechanism, first starts the output motor of the suction mechanism, which drives the suction fan to rotate in the fixed frame, drawing air out of the storage cabinet through the through slot, quickly reducing the air pressure inside the storage cabinet. Subsequently, the airflow flows through the connecting pipe through the mounting frame and the support frame. During this process, the heating element in the mounting frame heats the airflow. When the airflow enters the support frame, the cooling element quickly cools it, causing the water vapor in the airflow to condense and be discharged through the drain. The treated low-humidity airflow returns to the storage cabinet through the through hole, completing one cycle. This series of operations realizes the coordinated operation of heating, cooling, and dehumidification of the airflow, accelerating the pre-cooling process, improving pre-cooling efficiency, and effectively reducing the humidity inside the storage cabinet and the corn, effectively preventing the growth of microorganisms and ensuring the freshness of the corn.

[0012] 2. This vacuum pre-cooling and preservation device for fresh corn, by setting up a vibrating screen mechanism, controls the motor to drive the drive arm to rotate during the process of adding corn into the storage frame. The rotation of the drive arm is converted into the reciprocating up-and-down linear motion of the storage frame through the connecting arm, so that the corn is tightly arranged and the gaps are reduced, thereby increasing the storage capacity. At the same time, when the storage frame moves up and down, the limiting block slides smoothly along the limiting slide rail to ensure the stability of the storage frame during the vibration process and prevent the storage frame from shifting. These operations not only improve the utilization rate of storage space and increase the storage capacity of corn, but also ensure the stability of the storage frame vibration, guarantee the smooth progress of the entire pre-cooling process, and improve the reliability of the device during use.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] like Figure 1-5As shown, this utility model provides a technical solution: a vacuum pre-cooling and preservation device for fresh corn, including a storage cabinet 1, a suction mechanism 2 on one side of the storage cabinet 1, a heating mechanism 3 below the suction mechanism 2, and a cooling mechanism 4 below the heating mechanism 3. The suction mechanism 2 includes a fixing frame 201, which is fixedly connected to one side of the storage cabinet 1. The fixing frame 201 has several through slots 202 on the side facing the storage cabinet 1, which are connected to the storage cabinet 1. A suction fan 203 is rotatably connected between the inner walls of the fixing frame 201. The other side of the fixing frame 201... An output motor 204 is fixedly installed at the end, and the output end of the output motor 204 is connected to the suction fan 203. Because a suction mechanism 2 is provided, the output motor 204 in the suction mechanism 2 drives the suction fan 203 to rotate. When the suction fan 203 rotates in the fixed frame 201, it draws out the air in the storage cabinet 1 through the through groove 202, creating conditions for subsequent cooling and dehumidification operations and accelerating the pre-cooling process. The heating mechanism 3 includes a mounting frame 301, which is located below the fixed frame 201 and fixedly connected to one side of the storage cabinet 1. A heating element 302 is fixedly installed in the mounting frame 301.

[0021] The cooling mechanism 4 includes a support frame 401, which is fixedly connected to the storage cabinet 1. A cooling component 402 is fixedly installed inside the support frame 401. A drain outlet 403 is provided at the bottom of the support frame 401. Several through holes 404 are provided on the side of the support frame 401 facing the storage cabinet 1, and the through holes 404 are connected to the storage cabinet 1. Through the cooperation between the heating mechanism 3 and the cooling mechanism 4, when the airflow passes through the heating mechanism 3, the heating component 302 heats the airflow. When the airflow enters the cooling mechanism 4, the water vapor in the airflow quickly condenses under the action of the cooling mechanism 4, thereby removing the water vapor in the airflow, reducing the humidity inside the storage cabinet 1 and the corn, and preventing microorganisms. To ensure the freshness of corn, a connecting pipe 5 is provided between the fixed frame 201, the mounting frame 301 and the support frame 401. The fixed frame 201 and the mounting frame 301 are connected by the connecting pipe 5, and the mounting frame 301 and the support frame 401 are connected by the connecting pipe 5. Because of the connecting pipe 5, the airflow circulates between the fixed frame 201, the mounting frame 301 and the support frame 401 through the connecting pipe 5. The connecting pipe 5 ensures that the airflow flows smoothly between the suction mechanism 2, the heating mechanism 3 and the cooling mechanism 4, realizing the coordinated work of heating, cooling and dehumidification, and improving the efficiency of pre-cooling. A vacuum pump 6 is fixedly installed on the other side of the storage cabinet 1, and a sealed top cover 7 is provided on the top of the storage cabinet 1.

[0022] The storage cabinet 1 has a storage frame 8 inside. Four limiting blocks 9 are fixedly connected to the four corners of the bottom of the storage frame 8. Four limiting slide rails 10 are fixedly connected to the four corners of the inner wall of the storage cabinet 1. The four limiting blocks 9 slide between the inner walls of the four limiting slide rails 10. Through the cooperation between the limiting blocks 9 and the limiting slide rails 10, the storage frame 8 moves up and down, causing the limiting blocks 9 to move up and down within the limiting slide rails 10, thereby improving the stability of the storage frame 8 during vertical vibration and preventing it from shifting. The storage cabinet 1 also has a vibrating screen mechanism 11, which includes a control motor 1101. The control motor 1101 is fixedly installed on the outer wall of the storage cabinet 1, and its output end passes through the storage frame. A drive arm 1102 is fixedly connected to one side and one end of the cabinet 1. A connecting arm 1103 is rotatably connected to the other end of the drive arm 1102. The length of the connecting arm 1103 is greater than that of the drive arm 1102. The other end of the connecting arm 1103 is rotatably connected to the bottom of the storage frame 8. When corn is added into the storage frame 8, the control motor 1101 controls the drive arm 1102 to rotate. The rotation of the drive arm 1102 continuously pushes and pulls the connecting arm 1103. The connecting arm 1103 converts the rotation of the drive arm 1102 into the reciprocating up-and-down linear motion of the storage frame 8. Through such up-and-down movement, the corn is arranged more closely, avoiding excessive or insufficient local accumulation and reducing gaps. Thus, more corn can be stored in the same storage space, improving storage efficiency.

[0023] The working principle of this utility model is as follows: When using the device, open the sealed top cover 7 and add fresh corn into the storage frame 8. During the adding process, the control motor 1101 in the vibrating sieve mechanism 11 drives the drive arm 1102 to rotate. The connecting arm 1103 converts the rotation of the drive arm 1102 into linear motion, causing the storage frame 8 to move back and forth up and down, making the corn more compact and reducing gaps, thus storing more corn. Then, the output motor 204 in the suction mechanism 2 drives the suction fan 203 to rotate. When the suction fan 203 rotates in the fixed frame 201, it draws the air out of the storage cabinet 1 through the through groove 202. The airflow enters the fixed frame 201 and then enters the mounting frame 301 through the connecting pipe 5. The heating element 302 rapidly heats the passing airflow. After passing through the heating mechanism 3, the airflow enters the support frame 401 in the cooling mechanism 4. The cooling element 402 in the support frame 401 then rapidly cools the airflow, causing the water vapor in the airflow to condense and be adsorbed onto the cooling element 402. Under the action of gravity, the water vapor is discharged through the drain port 403. The airflow after removing the water vapor is discharged back into the storage cabinet 1 through the through hole 404, reducing the humidity and temperature inside the storage cabinet 1 and pre-cooling the corn inside the storage cabinet 1. After the humidity treatment is completed, the sealed top cover 7 is closed, and the vacuum pump 6 performs a vacuuming operation to reduce the air pressure inside the storage cabinet 1 and preserve the corn. Finally, the sealed top cover 7 is opened, the pre-cooled corn is taken out, and subsequent packaging and storage are carried out.
