Description

Technical Field

[0001] This utility model relates to the field of food safety testing for beef jerky, and more particularly to a food safety testing device for beef jerky. Background Technology

[0002] Food safety testing of beef jerky refers to the activity of testing and analyzing various factors (such as microorganisms, chemical contaminants, physical impurities, additive use, and packaging safety) that affect the quality and safety of beef jerky products and their production and processing, based on relevant national standards, regulations, and technical specifications, using scientific methods and means, in order to determine whether the beef jerky meets food safety requirements.

[0003] The microbiological testing steps for beef jerky mainly include sample collection and preparation, index detection, and result analysis and judgment: First, aseptic operation is followed to collect a representative sample (no less than 25g), which is then cut or crushed and weighed to add 25g to a sterile diluent to prepare a 1:10 sample homogenate, and then serially diluted as needed; then, index detection is performed, such as the total bacterial count using the plate count method, where the diluted homogenate is inoculated onto a plate, cultured, and counted; coliform bacteria are determined by primary fermentation and secondary fermentation tests combined with microscopic examination; pathogenic bacteria require enrichment culture, isolation and purification, biochemical identification, and serological tests; molds and yeasts are cultured and counted using specific culture media; finally, according to standards such as GB4789 series, qualitative or quantitative analysis is performed on the various test results to determine whether the sample meets the microbiological safety requirements.

[0004] In the pretreatment process of beef jerky samples for microbial testing, operators need to manually cut and grind the beef jerky to prepare the test samples before transferring and filling them. This process is not only cumbersome, time-consuming, and labor-intensive, but also prone to individual differences leading to inconsistent and uneven sample processing. Furthermore, manual operation is susceptible to human error, reducing the accuracy and repeatability of test results and affecting the efficiency and quality of beef jerky microbial testing. Therefore, a food safety testing device for beef jerky is proposed to address these issues. Utility Model Content

[0034] Reference Figure 1 , Figure 2 , Figure 6The shredding and conveying mechanism 2 also includes a connecting frame 220, which supports and fixes the first motor 221 and connects it to the shredding cylinder 212. The outer wall of the connecting frame 220 is fixedly connected to the outer wall of the shredding cylinder 212, and the first motor 221 is fixedly connected to the outer wall of the connecting frame 220. The first motor 221 provides rotational power to the second gear 222. The top of the output shaft of the first motor 221 is fixedly connected to the second gear 222. The second gear 222 transmits the power of the first motor 221 to the rotating rod 216 by meshing with the first gear 215. The shredding and conveying mechanism 2 also includes a second motor 223, which provides rotational power to the rotating shaft 224 and the shredder 225. The bottom of the second motor 223 is fixedly connected to the top of the shredding cylinder 212. The grinding and conveying mechanism 2 also includes a rotating shaft 224, which is used to connect the second motor 223 and the auger 225 to transmit rotational power. The output end of the second motor 223 is fixedly connected to the top of the rotating shaft 224. The auger 225 is fixedly connected to the outer wall of the rotating shaft 224. The auger 225 grinds the beef jerky under the drive of the rotating shaft 224. The grinding and conveying mechanism 2 also includes a support block 226, which is used to support and fix the tray 227 so that it can be smoothly conveyed on the conveying and testing table 1. The support block 226 is placed on the top of the conveying and testing table 1. The grinding and conveying mechanism 2 also includes a tray 227, which is used to hold physiological saline and the ground beef jerky sample. The outer wall of the tray 227 is inserted into the inner surface of the support block 226.

[0035] Reference Figure 2 The switching and adjusting mechanism 3 includes a telescopic rod 311, which adaptively extends and retracts when the shredder 212 rotates to ensure smooth rotation. The bottom of the telescopic rod 311 is fixedly connected to the top of the shredder 212. A connecting block 312 is fixedly connected to the inner rod of the telescopic rod 311. The connecting block 312 is hinged to the connecting frame 314 to realize the rotational connection of the shredder 212. The switching and adjusting mechanism 3 also includes an electric push rod 313, which provides power for the rotation of the shredder 212. The bottom of the electric push rod 313 is fixedly connected to the top of the support frame 211. A connecting frame 314 is fixedly connected to the inner rod of the electric push rod 313. The connecting frame 314 is hinged to the connecting block 312 to convert the thrust of the electric push rod 313 into the rotational force of the shredder 212. The inner surface of the connecting frame 314 is hinged to the outer wall of the connecting block 312.

[0036] Working principle: When microbial testing of beef jerky is required, the beef jerky to be tested is first placed inside the grinding drum 212. Starting motor 223 causes the output end of motor 223 to drive the fixedly connected rotating shaft 224 to rotate, thereby causing the shredder 225 fixedly connected to the outer wall of the rotating shaft 224 to fold. The shredder 225 can grind the beef jerky for subsequent microbial testing. Starting motor 221 causes the output shaft of motor 221 to drive gear 222 to rotate. Since gear 222 meshes with the outer wall of gear 215, the rotating gear 222... 222 will drive gear 215 to rotate, which in turn drives the rotating rod 216 fixedly connected to the inner wall to rotate. The rotating rod 216 then drives the conveying auger 217 fixedly connected to the outer wall to rotate. By opening the solenoid valve 218, the minced beef jerky can be discharged through the discharge cylinder 213 into the tray 227 containing saline solution. Since there are multiple sets of discharge cylinders 213, multiple trays 227 can be filled at the same time. After filling, the solenoid valve 218 can be closed so that the discharge cylinder 213 can be switched to the tray 227 that does not contain minced beef.

[0037] By activating the electric actuator 313, the inner rod of the electric actuator 313 pushes the connecting frame 314. Under the hinge action between the connecting frame 314 and the connecting block 312, the inner rod of the telescopic rod 311 slides adaptively. The connecting frame 314 drives the grinding cylinder 212 to rotate, which in turn drives the bottom discharge cylinder 213 to rotate. This allows the discharge cylinder 213 to rotate to the top of the remaining trays 227 that do not contain ground beef. Activating the solenoid valve 218 again allows the ground beef to be filled into the remaining trays 227. Subsequently, the carrying block 226 can be conveyed through the conveying detection table 1. The carrying block 226 can move the trays 227 into the food testing equipment 219, where microbial testing can be performed.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
