Description
Technical Field
[0001] The utility model relates to a new type of aseptic homogenizer for food detection, belonging to the technical field of homogenizers. Background Art
[0002] An aseptic homogenizer, also known as a beating homogenizer, makes the process of extracting bacteria from solid samples very simple. Just add the sample and diluent into a sterile sample bag, and then put the sample bag into the beating homogenizer to complete the sample treatment.
[0003] The distance between the existing beating plate and the cabinet door and the homogenization bag is too large, and the rotation angle of the beating plate is also within a certain range.
[0004] When actually using the homogenizer to homogenize a sample, due to the too large distance between the beating plate and the homogenization bag, the contact area between the beating plate and the homogenization bag is too small when the beating plate rotates to beat the homogenization bag, resulting in too small a beating force of the beating plate on the homogenization bag. Thus, the homogenization force of the homogenizer when homogenizing the sample is insufficient, and hard samples cannot be homogenized evenly, greatly reducing the accuracy of the experimental results, and further affecting the subsequent detection process and results, which is very inconvenient. Summary of the Utility Model
[0005] The technical problem to be solved by the utility model is to provide a new type of aseptic homogenizer for food detection, which solves the problem in the prior art that due to the too large distance between the beating plate and the homogenization bag, the contact area between the beating plate and the homogenization bag is too small when the beating plate rotates to beat the homogenization bag, resulting in too small a beating force of the beating plate on the homogenization bag. Thus, the homogenization force of the homogenizer when homogenizing the sample is insufficient, and hard samples cannot be homogenized evenly, greatly reducing the accuracy of the experimental results, and further affecting the subsequent detection process and results, which is very inconvenient.
[0006] In order to homogenize hard samples evenly when the homogenizer is used, the utility model provides a new type of aseptic homogenizer for food detection, which includes a box body with an opening and a cabinet door. A number of beating plates are arranged in the box body. A V-shaped plate is also fixed in the box body. An extrusion cavity for placing a sample is formed between the V-shaped plates. A feed port is opened at one end of the V-shaped plate. Both ends of the V-shaped plate are connected by a connecting structure, and the V-shaped plate has toughness.
[0007] By adopting the above technical solution, during the food detection process, when a sterile homogenizer is required for hard samples, first, the staff puts the sample bag to be detected into the extrusion cavity through the feed port, and places the open end of the sample bag on the feed port. Then the staff closes the box door. Then the staff drives the two ends of the V-shaped plate to approach each other until the inner walls of the two ends of the V-shaped plate abut against the sample surface. As the two ends of the V-shaped plate continue to approach, the sample is crushed due to being squeezed by the inner walls of the two ends. At the same time, the two ends of the V-shaped plate are connected by a connecting structure, and then the switch of the homogenizer can be turned on to homogenize the sample. Through the above operations, the hard sample is first squeezed and crushed and then homogenized.
[0008] The utility model is further arranged as follows: Handles are fixedly arranged on the outer walls of both ends of the V-shaped plate.
[0009] By adopting the above technical solution, when the staff drives the two ends of the open end of the V-shaped plate to approach each other by holding the handles, the convenience, safety and overall experience of the operation are improved.
[0010] The utility model is further arranged as follows: The connecting structure includes a connecting plate fixed to the other end of the V-shaped plate for being inserted into the feed port. The connecting plate has toughness. On the outer walls of both ends of the V-shaped plate above the feed port, isolation plates are integrally formed respectively, and the isolation plates are attached to the inner wall of the top of the box body.
[0011] By adopting the above technical solution, when the staff drives the two ends of the V-shaped plate to approach each other, the connecting plate and the feed port approach each other until the connecting plate is inserted into the feed port and the sample bag opening is pressed under the connecting plate. As the two ends of the V-shaped plate approach each other, the two isolation plates are driven to move towards each other, and the connection of the two ends of the V-shaped plate can be completed.
[0012] The utility model is further arranged as follows: The two open ends of the V-shaped plate or the two ends of the V-shaped plate are fixed by a clamping structure. The clamping structure includes a plurality of connecting blocks arranged on one side of the inner wall of the V-shaped plate, and a plurality of clamping parts for the connecting blocks to be inserted into are arranged on the other side of the inner wall of the V-shaped plate. The clamping parts include a fixed frame arranged on the V-shaped plate, and a plurality of fixed shafts are arranged in the fixed frame, and the connecting blocks are inserted between the plurality of fixed shafts.
[0013] By adopting the above technical solution, while the two ends of the V-shaped plate are connected, as the two ends of the V-shaped plate continue to approach, the outer peripheral wall of the other end of the connecting block abuts against a plurality of abutting rings. As the two ends of the V-shaped plate continue to approach, the connecting block enters the inside of the fixed frame from between the fixed shafts due to the rolling of the abutting rings, and the clamping of the two ends of the V-shaped plate can be completed. By clamping the two ends of the V-shaped plate, the two ends of the V-shaped plate will not separate during the homogenization process of the beating plate, so that the sample bag can be placed more stably in the extrusion cavity, ensuring the smooth progress of the homogenization process.
[0014] The present utility model is further configured as follows: A limiting structure for restricting the movement of the V-shaped plate is also provided inside the box body. The limiting structure includes a limiting groove opened on the inner wall of the box body, a limiting block is clamped in the limiting groove, and a V-shaped groove for the V-shaped plate to be clamped into is opened on the limiting block.
[0015] By adopting the above technical solution, when the beating plate homogenizes the sample, due to the instability of the connection between the lower part of the V-shaped plate and the box body, and the high-frequency beating of the beating plate on the V-shaped plate, the V-shaped plate moves inside the box body and its position deviates, resulting in incomplete homogenization of the sample and inaccurate test results. By clamping the V-shaped plate into the V-shaped groove, the contact area between the V-shaped plate and the box body is increased, so that the V-shaped plate can be stably fixed inside the box body, ensuring the smooth progress of the detection process and improving the detection efficiency and detection quality.
[0016] The present utility model is further configured as follows: A vibrating member is fixed on the V-shaped plate, the vibrating member is embedded in the limiting block, and a groove is opened on the limiting block. In this embodiment, the vibrating member is a vibrating motor.
[0017] By adopting the above technical solution, the vibrating motor has the functions of high-speed driving and strong vibration. The vibrating motor can drive the V-shaped plate to vibrate, thereby quickly realizing the dispersion and mixing of the sample, improving the homogenization effect and experimental efficiency, shortening the experimental operation time, ensuring the accuracy and reliability of the experiment, and greatly improving the experimental efficiency.
[0018] The present utility model is further configured as follows: Sound-absorbing cotton is pasted on one side of several beating plates close to the V-shaped plate.
[0019] By adopting the above technical solution, since the materials of the beating plate and the extrusion plate are relatively hard, a large amount of noise will be generated when the beating plate beats the extrusion plate II. The setting of the sound-absorbing cotton can effectively control and reduce the diffusion and interference of the noise, creating a more quiet and comfortable experimental environment.
[0020] The beneficial effects of the present utility model are as follows: A novel aseptic homogenizer for food detection includes a box body with an opening and a box door. Several beating plates are arranged inside the box body. A V-shaped plate is also fixed inside the box body. An extrusion cavity for placing the sample is formed between the V-shaped plates. A feed port is opened at one end of the V-shaped plate. Both ends of the V-shaped plate are connected through a connection structure. The V-shaped plate has toughness. Through the above settings, the homogenizer of the present application has sufficient force during homogenization of the sample, homogenizes hard samples evenly, greatly improves the accuracy of the experimental results, and further makes the subsequent detection process and results smooth and very convenient.

Specific embodiments
[0027] In order to facilitate the understanding of the technical means, creative features, achieved purposes and effects of the present utility model, the present utility model will be further described below with reference to specific drawings.
[0028] As Figure 2 , Figure 3 and Figure 4 shown, a new type of aseptic homogenizer for food detection includes a box body 1 with an opening and a box door 2. A plurality of flapping plates 3 are arranged in the box body 1. A V-shaped plate 4 is also fixed in the box body 1. An extrusion cavity 5 for placing samples is formed between the V-shaped plates 4. A feed inlet 6 is opened at one end of the V-shaped plate 4. The two ends of the V-shaped plate 4 are connected by a connection structure, and the V-shaped plate 4 has toughness.
[0029] Among them, handles 7 are fixed on the outer walls of both ends of the V-shaped plate 4.
[0030] During the food testing process, when a sterile homogenizer is required for hard samples, first, the staff puts the sample bag to be tested into the extrusion chamber 5 through the feed port 6, and places the open end of the sample bag on the feed port 6. Then the staff closes the box door 2. Next, the staff drives the two ends of the V-shaped plate 4 to approach each other through the handle 7 until the inner walls at both ends of the V-shaped plate 4 are in contact with the surface of the sample. As the two ends of the V-shaped plate 4 continue to approach, the sample is crushed due to the extrusion of the inner walls at both ends. At the same time, the two ends of the V-shaped plate 4 are connected by a connecting structure, and then the switch of the homogenizer can be turned on to homogenize the sample. By performing the above operations to first crush the hard sample and then homogenize the sample, the force for homogenization is sufficient when the homogenizer homogenizes the sample, the hard sample is homogenized evenly, and the damage of the homogenization bag is avoided, greatly improving the accuracy of the experimental results, and thus having no impact on the subsequent testing process and results, which is very convenient.
[0031] Among them, the setting of the handle 7 improves the convenience, safety and overall experience when the staff drives the two ends of the open end of the V-shaped plate 4 to approach each other by holding the handle 7.
[0032] As Figure 3 shown, the connecting structure includes a connecting plate 8 fixed to the other end of the V-shaped plate 4 for being inserted into the feed port 6. The connecting plate 8 has toughness. On the outer walls at both ends of the V-shaped plate 4 above the feed port 6, isolation plates 9 are integrally formed respectively, and the isolation plates 9 are attached to the inner wall of the top of the box body 1.
[0033] Among them, a clamping groove 10 is formed at the top of the box body 1, and both ends of the V-shaped plate 4 pass through the box body 1 from the clamping groove 10.
[0034] When the staff drives the two ends of the V-shaped plate 4 to approach each other, the connecting plate 8 and the feed port 6 approach each other until the connecting plate 8 is inserted into the feed port 6 and the sample bag opening is pressed under the connecting plate 8. As the two ends of the V-shaped plate 4 approach each other, the two isolation plates 9 are driven to move towards each other, and the connection of the two ends of the V-shaped plate 4 can be completed.
[0035] Among them, the setting of the two isolation plates 9 enables the two isolation plates 9 to isolate the inside of the box body 1 from the external environment when the size of the clamping groove 10 remains unchanged after the two ends of the V-shaped plate 4 are connected, preventing the external air from contaminating the sample. This setting is very important and convenient to operate.
[0036] As Figure 2 and Figure 5As shown, the two ends of the opening of the V-shaped plate 4 or both ends of the V-shaped plate 4 are fixed by a clamping structure. The clamping structure includes a number of connecting blocks 11 provided on one side of the inner wall of the V-shaped plate 4, and a number of clamping members for the connecting blocks 11 to snap into are provided on the other side of the inner wall of the V-shaped plate 4. The clamping members include a fixed frame 12 provided on the V-shaped plate 4, and a number of fixed shafts 13 are provided inside the fixed frame 12. The connecting blocks 11 snap into between the number of fixed shafts 13.
[0037] Among them, abutting rings 14 are sleeved on each of the number of fixed shafts 13.
[0038] In addition, the connecting blocks 11 are in an "Ω" shape and are penetrated in the middle. One end of the connecting block 11 is used to snap into between the fixed shafts 13, and the other end of the connecting block 11 is fixed to the inner wall of the other end of the V-shaped plate 4.
[0039] When the two ends of the V-shaped plate 4 are connected, as the two ends of the V-shaped plate 4 continue to approach, the outer peripheral wall of the other end of the connecting block 11 abuts against the number of abutting rings 14. As the two ends of the V-shaped plate 4 continue to approach, the abutting rings 14 roll, causing the connecting block 11 to enter the inside of the fixed frame 12 from between the fixed shafts 13, and thus the two ends of the V-shaped plate 4 can be clamped. By clamping the two ends of the V-shaped plate 4, during the homogenization process of the V-shaped plate 4 by the beating plate 3, the two ends of the V-shaped plate 4 will not separate, and further the sample bag can be placed more stably in the extrusion cavity 5, ensuring the smooth progress of the homogenization process and the accuracy of the experimental results.
[0040] Among them, the setting of the abutting rings 14 enables the connecting block 11 to enter the fixed frame 12 more smoothly.
[0041] In addition, since the inner wall of the V-shaped plate 4 is smooth, the homogenizer will not cause damage to the sample bag during the homogenization process.
[0042] Such as Figure 2 and Figure 3 As shown, a limiting structure for restricting the movement of the V-shaped plate 4 is further provided inside the box body 1. The limiting structure includes a limiting groove 15 opened on the inner wall of the box body 1, a limiting block 16 is clamped in the limiting groove 15, and a V-shaped groove 17 for the V-shaped plate 4 to snap into is opened on the limiting block 16.
[0043] When the beating plate 3 homogenizes the sample, due to the instability of the connection between the lower part of the V-shaped plate 4 and the box body 1, and the high-frequency beating of the beating plate 3 on the V-shaped plate 4, the V-shaped plate 4 moves inside the box body 1 and its position shifts, resulting in incomplete homogenization of the sample and inaccurate detection results. By snapping the V-shaped plate 4 into the V-shaped groove 17, the contact area between the V-shaped plate 4 and the box body 1 is increased, enabling the V-shaped plate 4 to be stably fixed inside the box body 1, ensuring the smooth progress of the detection process and improving the detection efficiency and detection quality.
[0044] Such as Figure 3As shown, a vibrating member 19 is fixed on the V-shaped plate 4. The vibrating member 19 is embedded in the limiting block 16, and a groove 18 is formed on the limiting block 16. In this embodiment, the vibrating member 19 is a vibrating motor.
[0045] The vibrating motor has the functions of high-speed driving and strong vibration. The vibrating motor can drive the V-shaped plate 4 to vibrate, thereby quickly realizing the dispersion and mixing of the sample, improving the homogenization effect and experimental efficiency, shortening the experimental operation time, ensuring the accuracy and reliability of the experiment, and greatly improving the experimental efficiency.
[0046] As Figure 4 shown, sound-absorbing cotton 20 is pasted on one side of each of the several flapping plates 3 close to the V-shaped plate 4.
[0047] Since the materials of the flapping plate 3 and the extrusion plate are relatively hard, a relatively large noise will be generated when the flapping plate 3 flaps the second extrusion plate. The setting of the sound-absorbing cotton 20 can effectively control and reduce the diffusion and interference of the noise, creating a more quiet and comfortable experimental environment.
[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope claimed by the present invention. The scope claimed by the present invention is defined by the appended claims and their equivalents.
