Description

Technical Field

[0001] This utility model relates to the field of food testing technology, specifically a testing device for food processing. Background Technology

[0002] During food processing, samples must be taken for testing to ensure food safety.

[0003] A search revealed a Chinese patent publication number CN212410176U, which discloses a food testing device for food processing. This device divides the observation chamber into three compartments by inserting a partition plate inside. Food solutions of different heights are drawn into these three compartments via three connecting tubes of varying lengths, allowing for sampling of different locations within the test solution. However, in practical applications, each sample must be released from the discharge tube and stored separately, and then cleaned before reuse. This cumbersome operation reduces user efficiency. Therefore, we propose a testing device for food processing. Utility Model Content

[0004] The technical problem to be solved by this application is that each time a sample is tested, the sample needs to be released from the sample tube and stored separately. After being released, it needs to be cleaned before it can be used again. This operation is cumbersome and reduces the user's work efficiency.

[0005] To solve the above technical problems, this application provides a testing device for food processing, including a vacuum chamber. Three connecting cylinders are installed in a circular array at the bottom of the vacuum chamber. A syringe is threaded on the inner side of the connecting cylinder. A syringe piston is provided inside the syringe. The connecting cylinder is used to disassemble a single syringe. The syringe piston is used to store the sample after the single syringe is inverted. There are three connection holes arranged in a ring at the bottom of the suction chamber and connected to the inside of the connecting cylinder. Three limiting mechanisms are arranged in a ring at the bottom of the suction chamber and above the connection holes. After a single syringe is disassembled, the corresponding connection hole is closed by the limiting mechanism, so as to simultaneously sample different numbers of syringes.

[0006] In some embodiments, the limiting mechanism includes a fixed cover installed at the bottom of the air extraction chamber, with multiple through holes arrayed at the lower end of the outer side of the fixed cover, and a rubber pad slidably connected to the upper end of the inner side of the fixed cover, the rubber pad being connected to the top of the inner side of the fixed cover by a compression spring.

[0007] In some embodiments, a support rod is symmetrically mounted on the bottom of the rubber pad, and the bottom end of the support rod extends into the connection hole and presses against the top of the syringe.

[0008] In some embodiments, an air extraction chamber piston is provided inside the air extraction chamber, and a pull rod extending out of the top of the air extraction chamber piston is installed on the top of the air extraction chamber.

[0009] In some embodiments, a connecting ring is provided at the bottom of the syringe, and a needle tube is threadedly connected to the inner side of the connecting ring.

[0010] In some embodiments, a first rubber ring is tensioned on the outer side of the syringe piston and fits against the inner wall of the syringe.

[0011] In some embodiments, a second rubber ring is tensioned on the outer side of the suction chamber piston and fits against the inner wall of the suction chamber.

[0012] This utility model has at least the following beneficial effects: A syringe piston is installed in the syringe. When a sample is drawn, the sample enters the cavity between the syringe and the syringe piston. After the sample is drawn, the syringe is disassembled to test the sample. For multiple tests, only a new syringe needs to be installed, and there is no need to pour out the sample, which reduces the time of multiple samplings. The syringe can be stored upside down, which simplifies the user's operation steps and improves the user's work efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figure 1-5 This utility model provides a technical solution: a testing device for food processing, including a vacuum chamber 1. Three connecting cylinders 2 are installed in a circular array at the bottom of the vacuum chamber 1. A syringe 3 is threaded on the inner side of the connecting cylinder 2. The connecting cylinder 2 is used to disassemble a single syringe 3. The syringe piston 4 is used to store the sample after the single syringe 3 is inverted. The lower end of the syringe 3 has a discharge hole with a sealing plug inside. When it is necessary to remove the liquid sample from the syringe 3, the sealing plug is removed and the sample is discharged from the discharge hole by squeezing the syringe piston 4.

[0017] The syringe 3 has a connecting ring 301 at the bottom, and a rubber stopper is embedded at the bottom of the connecting ring 301 to seal the connecting ring 301. The inner side of the connecting ring 301 is threaded to the needle tube 302, and the outer side of the needle tube 302 is fitted with a sealing sleeve to seal and protect the needle tube 302. All three syringes 3 are made of transparent material and have scales on the outside to facilitate the user to observe the dosage. The three needle tubes 302 are of different lengths to be suitable for drawing solutions of different liquid levels.

[0018] The syringe 3 is equipped with a syringe piston 4 inside. The outside of the syringe piston 4 is tensioned and fitted with a first rubber ring 401 that fits against the inner wall of the syringe 3. The first rubber ring 401 increases the seal between the syringe piston 4 and the syringe 3. The suction chamber 1 is equipped with a suction chamber piston 5 inside. The outside of the suction chamber piston 5 is tensioned and fitted with a second rubber ring 501 that fits against the inner wall of the suction chamber 1. The second rubber ring 501 achieves a seal between the suction chamber 1 and the suction chamber piston 5. A pull rod 6 is installed on the top of the suction chamber piston 5, extending out of the top of the suction chamber 1.

[0019] There are three connecting holes 101, arranged in a ring array at the bottom of the suction chamber 1 and connected to the inside of the connecting cylinder 2. Three limiting mechanisms 7 are arranged in a ring array at the bottom of the suction chamber 1 and above the connecting holes 101. After a single syringe 3 is disassembled, the limiting mechanism 7 is used to close the corresponding connecting hole 101, so as to achieve simultaneous sampling of different numbers of syringes 3.

[0020] The limiting mechanism 7 includes a fixed cover 8 installed at the bottom of the inside of the suction chamber 1. Multiple through holes 801 are arrayed at the lower end of the outer side of the fixed cover 8. A rubber pad 10 is slidably connected to the upper end of the inside of the fixed cover 8. The rubber pad 10 and the top of the inside of the fixed cover 8 are connected by a compression spring 9. Support rods 11 are symmetrically installed at the bottom of the rubber pad 10. The bottom end of the support rod 11 extends into the connection hole 101 and presses against the top of the syringe 3.

[0021] When the support rod 11 is not subjected to external pressure, the rubber pad 10 fits against the connection hole 101 of the suction chamber 1, thus closing the connection hole 101. When extracting the solution food, remove the sealing sleeve of the connecting ring 301 and the sealing sleeve of the needle tube 302, thread the needle tube 302 to the connecting ring 301, and then connect the syringe 3 with the needle tube 302 to the connecting cylinder 2. During connection, the support rod 11 moves upward under the pressure of the syringe 3, and the support rod 11 drives the rubber pad 10 to move upward, opening the connection hole 101 at the corresponding position. Then, place the whole assembly above the solution food to be extracted, allowing needle tubes 302 of different lengths to enter different liquid levels of the solution food. Then, pull the lever 6 upward, and the lever 6 drives the piston 5 of the suction chamber and... The second rubber ring 501 slides, and the gas inside the syringe 3 enters the suction chamber 1 through the connecting hole 101 and the through hole 801, driving the syringe piston 4 and the first rubber ring 401 to move upward. Different liquid levels of food solutions enter different syringes 3, thus completing the sampling. When multiple samplings are required, simply disassemble the syringe 3 from the connecting tube 2 and connect the new syringe 3 to the connecting tube 2 to extract samples again, reducing the time of multiple samplings. After disassembly, the syringe 3 can be inverted and the sealing sleeve can be put on the outside of the needle tube 302, or the needle tube 302 can be removed and the rubber stopper can be inserted into the connecting ring 301 for sealing, realizing the individual storage of samples in the syringe 3, simplifying the user's operation steps, and thus improving the user's work efficiency.

[0022] Example 2 Please see Figure 6 and Figure 7This utility model provides a technical solution: Based on embodiment 1, this utility model provides another technical solution: The syringe 3 is a straight cylinder with openings at both the top and bottom, and the three syringes 3 have different lengths to accommodate the extraction of solid food from different positions. The size of the discharge hole at the lower end of the syringe 3 can be adaptively increased according to actual conditions to accommodate the discharge of solid food from the discharge hole. A rotating rod 12 is rotatably installed at the bottom inside the syringe 3, and a baffle 13 is installed on the outer side of the rotating rod 12. Both sides of the rotating rod 12 are provided with torsion springs 14 connected to the inside of the syringe 3. The inside of the syringe 3 is provided with space for the torsion springs 14 to rotate. The upper end of the outer side of the baffle 13 is provided with an arc-shaped surface to reduce the frictional resistance between the baffle 13 and the syringe 3 when the baffle 13 rotates. The lower end of the outer side of the baffle 13 is tensioned. A third rubber ring 15 is fitted, which seals the gap between the baffle 13 and the syringe 3. When extracting solid food, the pull rod 6 is moved, which drives the suction chamber piston 5 and the second rubber ring 501 to slide, allowing air inside the syringe 3 to enter the suction chamber 1. This drives the syringe piston 4 to move to the corresponding scale, and then the syringe 3 is moved toward the solid food. The baffle 13 is squeezed into the syringe 3 by the solid and rotates, tightening the torsion spring 14. This allows the solid food to pass through the gap between the baffle 13 and the syringe 3 and enter the cavity between the syringe 3 and the syringe piston 4. After extraction, the syringe 3 is moved away from the solid food. The baffle 13 is no longer squeezed by external force, and the rebound force of the torsion spring 14 drives the baffle 13 to rotate in the opposite direction and close the bottom of the syringe 3, thus completing the sampling of solid food.
