Description

Technical Field

[0001] The utility model relates to the field of food processing, and particularly relates to a drying room for making beef jerky. Background Art

[0002] In the field of food processing, especially in the process of making beef jerky, drying is a key link;

[0003] Existing drying rooms usually use hot air to blow directly from the lower part and extract moisture from the upper part for drying. However, in this direct blowing mode, the hot air will flow along a fixed straight line direction, resulting in uneven heat distribution inside the drying room;

[0004] This uneven heating condition makes it difficult to achieve an ideal drying effect for beef jerky. Some beef jerky may be over-dried, affecting the taste and quality, while some other parts may not be dried sufficiently, leaving too much moisture remaining, which is not conducive to preservation, directly leading to a decline in the economic benefits of the enterprise. At the same time, it will also extend the drying time and increase energy consumption. Content of the Utility Model

[0005] In order to solve the above existing problems, the utility model provides a drying room for making beef jerky.

[0006] The utility model is realized through the following technical solutions:

[0007] A drying room for making beef jerky includes a drying room and a blower on its outer side. The blower air outlet is connected to a heater inside the drying room through an air supply pipe. A main exhaust pipe is arranged below the heater, and the main exhaust pipe is connected to the air outlet of the drying room. Inside the air outlet, a plurality of adjusting vanes for adjusting the wind direction are rotatably supported. The upper part of the adjusting vane is rotatably connected to a reciprocating rod that can perform reciprocating motion. The end of the reciprocating rod is slidably connected to a transmission component that enables it to perform reciprocating motion. A second air outlet that can perform reciprocating motion through a sliding mechanism is arranged on the side wall of the drying room. The second air outlet is connected to the main exhaust pipe through a corrugated hose.

[0008] Further optionally, the transmission component includes a driving motor. A crank is fixedly connected to the output shaft of the driving motor, and a connecting rod is hinged to the end of the crank.

[0009] Further optionally, a sliding groove is formed on the connecting rod, and the sliding rod at the end of the reciprocating rod is slidably connected to the sliding groove.

[0010] Further optionally, the sliding mechanism includes a slide rail that is slidably connected to the second air outlet. A lead screw is rotatably supported on the upper part outside the slide rail. A nut slider is threadedly slidably connected to the lead screw. The nut slider is fixedly connected to the second air outlet through a connecting bracket. One end of the lead screw is connected to a control motor.

[0011] Further optionally, it further includes an automatic control system, which includes a first temperature sensor, a second temperature sensor and a humidity sensor arranged in the drying room. The temperature sensors, the second temperature sensor and the humidity sensor are electrically connected to a PLC controller, and the PLC controller is respectively electrically connected to a driving motor, a control motor, a blower and a heater.

[0012] Compared with the existing technology, the beneficial effects of the present utility model are as follows: By arranging adjustable blades capable of reciprocating movement and an air outlet capable of reciprocating movement in the air outlet, a series of problems caused by the hot air blowing directly and resulting in too fast local heating are fundamentally solved, which better ensures the uniform distribution of the hot air in the drying room, improves the quality and efficiency of beef jerky drying, ensures the consistency of product quality, greatly shortens the drying time, and reduces energy consumption.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The present utility model will be further described in detail below in conjunction with the drawings and the specific embodiments:

[0020] As Figure 1 , 2, as shown in Figures 3, 5, a drying room for making beef jerky includes a drying room 1 and a blower 2 outside it. The air outlet of the blower 2 is connected to a heater 4 inside the drying room 1 through an air supply pipe 3. A main exhaust pipe 5 is arranged below the heater 4, and the main exhaust pipe 5 is connected to the air outlet 6 of the drying room 1. Inside the air outlet 6, a plurality of adjusting vanes 7 for adjusting the wind direction are rotatably supported. The upper part of the adjusting vane 7 is rotatably connected to a reciprocating rod 8 that can perform reciprocating motion. The end of the reciprocating rod 8 is slidably connected to a transmission component that enables it to perform reciprocating motion. A second air outlet 10 that can perform reciprocating motion through a sliding mechanism is arranged on the side wall of the drying room 1, and the second air outlet 10 is connected to the main exhaust pipe 5 through a corrugated hose 11.

[0021] As Figure 3 , 4 shown, the transmission component includes a driving motor 9. A crank 12 is fixedly connected to the output shaft of the driving motor 9, and a connecting rod 13 is hinged to the end of the crank 12.

[0022] As Figure 3 , 4 shown, a chute 14 is formed on the connecting rod 13, and the chute 14 is slidably connected to the sliding rod at the end of the reciprocating rod 8.

[0023] As Figure 2 , 3 , 5 shown, the sliding mechanism includes a slide rail 15 slidably connected to the second air outlet 10. A lead screw 16 is rotatably supported on the upper part outside the slide rail 15. A nut slider 17 is threadedly slidably connected to the lead screw 16, and the nut slider 17 is fixedly connected to the second air outlet 10 through a connecting bracket 18. One end of the lead screw 16 is connected to a control motor 19.

[0024] As Figure 1 , 2 , 3, 5 shown, it further includes an automatic control system. The automatic control system includes a first temperature sensor 20, a second temperature sensor 21, and a humidity sensor 22 arranged inside the drying room 1. The temperature sensor 20, the second temperature sensor 21, and the humidity sensor 21 are electrically connected to a PLC controller 23. The PLC controller 23 is respectively electrically connected to the driving motor 9, the control motor 19, the blower 2, and the heater 4.

[0025] The implementation principle of a drying room for making beef jerky in an embodiment of this application is as follows:

[0026] When the drying room 1 is in operation, the PLC controller 23 will send a signal to start the fan 2 and the heater 4. The fan 2 will suck the air purified by the purifier 24 from the outside into the air supply pipe 3 and send it into the heater 4 for heating. The heated hot air will be transported through the main exhaust pipe 5 to the air outlet 6 and the second air outlet 10. When the hot air is transported to the air outlet 6, the PLC controller 23 will send a signal to start the drive motor 9. After the drive motor 9 is started, it will drive the crank 12 and the connecting rod 13 to perform circular motion. The sliding rod at the end of the reciprocating rod 8 slides in the chute 14, and at the same time, the reciprocating rod 8 performs reciprocating motion. While the reciprocating rod 8 performs reciprocating motion, it will drive the adjusting blade 7 to swing left and right, so that the hot air flows fully and evenly in different directions, so as to make the heat distribution in the drying room 1 uniform;

[0027] At the same time, the temperature sensor 20 and the second temperature sensor 21 will collect the temperature inside the drying room 1 and send the data to the PLC controller 23. The PLC controller 23 will judge whether the temperature inside the drying room 1 is uniform according to the collected temperature difference (when the difference is 3-8 degrees Celsius, it will be considered that the heating is uneven). When it is detected that the heating is uneven, the PLC controller 23 starts the control motor 19 to rotate forward to drive the lead screw 16 to rotate. The nut slider 17 threadedly connected to the lead screw 16 moves, and the nut slider 17 thus drives the second air outlet 10 to move through the connecting bracket 18. When it moves to the end of the slide rail 15, the PLC controller 23 drives the control motor 19 to reverse to make the nut slider 17 move in the reverse direction, so as to realize the reciprocating movement of the second air outlet 10 along the slide rail 15 and ensure the relative uniformity of the temperature inside the drying room 1;

[0028] When the temperatures of the temperature sensor 20 and the second temperature sensor 21 are the same, the PLC controller 23 will send a signal to stop the rotation of the control motor 19, and at the same time, the second air outlet 10 will stop at the end of the slide rail 15;

[0029] When the drying room 1 is performing drying operations, moisture will be generated. When the data collected by the humidity sensor 22 is greater than the set value, the PLC controller 23 will send a signal to start the dehumidifying fan 26. The dehumidifying fan 26 will discharge the moisture inside the drying room 1 along the dehumidifying pipe 25 to the outside, so as to ensure the dryness inside the drying room 1.
