[0002] Beef jerky contains a variety of minerals and amino acids needed by the human body. It not only maintains the chewy flavor of beef, but also does not deteriorate for a long time. At present, the preparation of beef jerky requires the selection of beef that has passed health inspections, trimming off the fat muscle membrane, broken bones, etc., cutting it into long strips, soaking it in circulating water for 24 hours, then marinating and air-drying the beef, and finally baking and packaging it.

DETAILED DESCRIPTION

[0035] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0036] Example 1

[0037] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig.10 , Fig.11As shown, a beef jerky microorganism detection sampling device comprises a sampling box 1, and a plurality of sampling barrels 2 are rotatably arranged on the inner side of the sampling box 1. In the present embodiment, three sampling barrels 2 are arranged, and the specific number can be flexibly set according to the actual situation. The sampling barrel 2 adopts a hollow circular ring structure penetrating from top to bottom, and a beef jerky 7 is suspended and fixedly arranged on the inner side of the sampling barrel 2. The beef jerky 7 is arranged in the central part of the sampling barrel 2, and a crushing mechanism 5 is arranged on the inner side of the three sampling barrels 2. The crushing mechanism 5 comprises a crushing roller 501 arranged on the inner side of the sampling barrel 2, and a plurality of crushing teeth 502 are arranged on the outer side of the crushing roller 501. A crushing motor 503 for driving the crushing roller 501 to rotate is arranged on the inner side of the sampling barrel 2. When in use, the crushing roller 501 is driven to rotate by the crushing motor 503, so that the plurality of crushing teeth 502 on the outer side of the crushing roller 501 can be driven to rotate, thereby cutting and sampling the beef jerky 7 on the inner side of the sampling barrel 2.

[0038] like Figure 4 , Figure 5 , Fig.10 , Fig.11 As shown, the outer sides of the three sampling barrels 2 are respectively provided with depth adjustment mechanisms 3 for driving the crushing mechanism 5 to slide along the diameter of the sampling barrel 2. The depth adjustment mechanism 3 includes a guide barrel 304 fixedly arranged at the upper and lower ends of the sampling barrel 2. Slide plates 301 are slidably arranged on the inner sides of the two guide barrels 304. The two slide plates 301 slide through the sampling barrel 2. The two ends of the crushing roller 501 are respectively rotatably arranged between the two slide plates 301. The crushing motor 503 is fixedly arranged on the slide plate 301. One end of the two slide plates 301 is commonly fixedly provided with a connecting plate 302 located on the outer side of the sampling barrel 2. The outer side of the sampling barrel 2 is fixedly provided with There is an electric telescopic rod 303 for driving the connecting plate 302 to move. When it is necessary to cut and sample beef jerky of different depths, it is only necessary to drive the crushing roller 501 to rotate through the crushing motor 503, and then drive the connecting plate 302 to move horizontally through the electric telescopic rod 303, thereby driving the slide plates 301 at both ends of the crushing roller 501 to slide along the diameter of the sampling tube 2, and then drive the crushing roller 501 to move along the diameter of the sampling tube 2, so that the crushing roller 501 moves along the diameter of the beef jerky, so that the beef jerky can be cut and sampled at different depths, and the beef jerky outside the insertion pin 601 can be cut and sampled at different depths.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Fig. 9As shown, a synchronous driving mechanism 4 for driving the three sampling tubes 2 to rotate simultaneously is arranged on the upper side of the sampling box 1, and the synchronous driving mechanism 4 includes a gear ring 403 fixedly sleeved on the outer side of the upper ends of the three sampling tubes 2. A servo motor 401 is fixedly arranged on the upper side of the sampling box 1, and a central gear 402 that meshes with the three gear rings 403 is fixedly arranged on the output end of the servo motor 401. Generally, the cross-section of the beef jerky 7 is square and has a long strip structure, and in order to improve the cutting efficiency of the beef strips, a machine is used to cut the long strip structure so that the shape of the beef jerky 7 is consistent. When it is necessary to cut and sample the four sides of the beef jerky, it only needs to be driven by the servo motor. 401 drives the central gear 402 to rotate, thereby causing the ring gear 403 to rotate 90°, which can drive the sampling tube 2 to rotate 90°, thereby causing the crushing roller 501 inside the sampling tube 2 to rotate 90° relative to the beef jerky 7. Repeating the above-mentioned depth adjustment mechanism 3 drives the crushing mechanism 5 to move radially, the other side of the beef jerky 7 can be cut and sampled at different depths. Similarly, when the servo motor 401 drives the central gear 402 to rotate, thereby causing the ring gear 403 to rotate 180° and 270°, the other side of the beef jerky can be cut and sampled at different depths, and finally the four sides of the beef jerky 7 are cut and sampled at different depths.

[0040] Example 2

[0041] A further improvement on the basis of Example 1 is that Figure 1 , Figure 2 , Figure 6 , Figure 7As shown, the upper side of the sampling box 1 is provided with three sampling fixing components 10 that cooperate with the upper end of the sampling tube 2. The sampling fixing component 10 includes a positioning groove 1001 opened on the upper side of the sampling box 1, and the bottom of the positioning groove 1001 is provided with a sampling port 1002 that penetrates the upper side of the sampling box 1. The sampling port 1002 is connected to the sampling tube 2 and is concentrically arranged with the sampling tube 2. The positioning groove 1001 and the sampling port 1002 form a stepped structure. The bottom edge of the positioning groove 1001 is provided with a plurality of screw holes 100 3. In this embodiment, three screw holes 1003 are provided, and the specific number can be flexibly adjusted. Three sample outlets 8 are provided on the lower side of the sampling box 1. The sample outlets 8 are matched with the lower end of the sampling tube 2. The sample outlets 8 are connected with the sampling tube 2 and are concentrically arranged with the sampling tube 2. The inner sides of the three sampling tubes 2 are all provided with a pin assembly 6 matched with the injection fixing assembly 10. The pin assembly 6 includes a pin 601 that is movably inserted into the inner side of the sampling tube 2 from the injection port 1002. The pin 601 is made of a metal material with good thermal conductivity. The beef jerky 7 is inserted into the outer side of the pin 601, and a top plate 602 cooperating with the positioning groove 1001 is fixedly provided on the upper end of the pin 601. The pin 601 can be inserted into the beef jerky 7 during the drying or drying process. On the one hand, the inside of the beef jerky 7 can be heated by the pin 601 with good thermal conductivity, thereby improving the drying efficiency of the beef jerky 7. On the other hand, in the process of cutting and sampling, cutting and sampling can be directly carried out to avoid contamination of the beef jerky 7 during the processing process, thereby affecting the detection accuracy. In the process of hanging and fixing the beef jerky on the inner side of the sampling tube 2, the pin 601 with the beef jerky 7 inserted is inserted into the inner side of the sampling tube 2 from the sampling port 1002, and then the top plate 602 at the upper end of the pin 601 falls into the inner side of the positioning groove 1001, and then the screw passes through the through hole 603 and cooperates with the screw hole 1003, so that the top plate 602 is fixed on the upper side of the positioning groove 1001, so that the beef jerky can be fixedly hung on the inner side of the sampling tube 2.

[0042] like Figure 3 As shown, the inner sides of the three sample outlets 8 are all provided with positioning components 9 that cooperate with the pin components 6. The positioning components 9 include a positioning rod 901 fixedly provided on the inner side of the sample outlet 8. A positioning plate 902 is fixedly provided on one end of the positioning rod 901. The positioning plate 902 is located at the inner center of the sample outlet 8. The positioning plate 902 can abut against the lower end of the pin 601 to position one end of the pin 601, thereby preventing the pin 601 from shaking during the process of cutting and sampling the beef jerky outside the pin 601, thereby affecting the cutting and sampling effect and improving the detection accuracy.

[0043] like Figure 1 , Figure 6As shown, a plurality of through holes 603 cooperating with the screw holes 1003 are provided at the edge of the top plate 602. In the present embodiment, three through holes 603 are provided, and the specific number can be flexibly selected according to actual conditions. An air inlet pipe 604 for inflating the inner side of the sampling tube 2 is provided on the top plate 602. The lower end of the air inlet pipe 604 passes through the top plate 602, and a valve (not shown in the figure) is provided on the air inlet pipe 604. When in use, when the top plate 602 is fixed on the inner side of the positioning groove 1001, helium, nitrogen or neon is then filled into the inner side of the sampling tube 2 through the air inlet pipe 604. Since helium, nitrogen or neon are stable gases and have a lower density than air, the air inside the sampling tube 2 will be discharged from the bottom of the sampling tube 2, so that the beef jerky is in an environment of helium, nitrogen or neon. This can ensure that the beef jerky 7 is not contaminated during the cutting and sampling process, thereby improving the accuracy of subsequent inspections.

[0044] It should be noted that, when using the beef jerky microbial detection sampling device, the pin 601 with the beef jerky 7 inserted therein is inserted into the inner side of the sampling tube 2 from the sampling port 1002, and then the top plate 602 at the upper end of the pin 601 falls into the inner side of the positioning groove 1001, and then the screw passes through the through hole 603 to cooperate with the screw hole 1003, so that the top plate 602 is fixed to the upper side of the positioning groove 1001, and then helium, nitrogen or neon is filled into the inner side of the sampling tube 2 through the air inlet pipe 604, so that the air inside the sampling tube 2 is discharged from the bottom of the sampling tube 2, so that the beef jerky 7 is in an environment of helium, nitrogen or neon, and then the crushing roller 501 is driven to rotate by the crushing motor 503, and then the electric telescopic rod 303 is used. The connecting plate 302 is driven to move horizontally, and then the slide plates 301 at both ends of the crushing roller 501 are driven to slide along the diameter of the sampling tube 2, so that the beef jerky outside the pin 601 can be cut and sampled at different depths. Finally, the central gear 402 is driven to rotate by the servo motor 401, and then the ring gear 403 is rotated 90°, which can drive the sampling tube 2 to rotate 90°, and then the crushing roller 501 on the inner side of the sampling tube 2 is rotated 90° relative to the beef jerky 7. Similarly, when the servo motor 401 drives the central gear 402 to rotate, and then the ring gear 403 is rotated 180° and 270°, the other side of the beef jerky can be cut and sampled at different depths, and finally the four sides of the beef jerky 7 are cut and sampled at different depths.

[0045] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
