The cover plate 2 is embedded in the upper part of the test dish 1 and is sealed and fixed by a locking piece, ensuring that the test dish 1 is in a sealed space.

[0032] A feed cylinder 3 is rotatably arranged above the cover plate 2, and a material guide assembly for uniform feeding is arranged inside the feed cylinder 3. By rotating the feed cylinder 3, the yeast culture enters the interior of the test dish 1 in sequence and uniformly through the material guide assembly inside the feed cylinder 3. A material distributor assembly is arranged between the feed cylinder 3 and the test dish 1, and the two outlets of the material distributor assembly penetrate the cover plate 2 and are respectively placed on both sides of the partition 17. The yeast culture enters the interior of the material distributor assembly through the feed cylinder 3, and the materials of the two groups of tests are respectively put into the test cavities on both sides of the partition 17 through the material distributor assembly. The test dish 1 is made of transparent material, and the test results of the two parts are observed through the test dish 1 made of colorless and transparent material.

[0033] By adopting the above structure, the accuracy of the experimental results is improved by analyzing the two groups of results simultaneously, and the efficiency of the test process is improved by performing two groups of comparisons at the same time. The feed cylinder 3 is rotated to allow the yeast culture to enter the test dish 1 in sequence through the internal material guide component, thereby avoiding the accumulation of feed, thereby ensuring the smoothness of the feeding process.

[0034] Among them, the material distribution component includes a receiving hopper 27 and a distribution bin 5 arranged below the feed barrel 3. The receiving hopper 27 is located below the discharge port of the feed barrel 3, so that the material transported out of the feed barrel 3 falls into the interior of the receiving hopper 27.

A distribution pipe 6 is symmetrically arranged between the distribution bin 5 and the cover plate 2, and the distribution pipe 6 passes through the cover plate 2 and extends to the interior of the test dish 1. One end of two distribution pipes 6 are symmetrically embedded and installed on the outer wall of the distribution bin 5 near the bottom, and the other ends of the two distribution pipes 6 respectively pass through the cover plate 2 and extend to the interior of the test dish 1, and the two distribution pipes 6 are respectively located on both sides of the partition 17.

[0035] The material distribution pipe 6 is fixedly embedded in the through hole of the cover plate 2, and the material distribution bin 5 is connected to the inside of the test dish 1 through the two material distribution pipes 6, that is, the receiving hopper 27 and the test dish 1 form two feeding pipes. The inner cavity of the material distribution bin 5 is rotatably provided with a material distribution guide plate 20. The circular material distribution guide plate 20 is fitted on the inner wall of the material distribution bin 5 and rotates. The top of the cover plate 2 is provided with an adjustment component for rotating the material distribution guide plate 20. Through the adjustment component on the cover plate 2, the material distribution guide plate 20 is fitted on the inner wall of the material distribution bin 5 and rotates.

[0036] With the above structure, the two material distribution pipes 6 are opened and closed respectively by rotating and adjusting the position of the material distribution guide plate 20, so that the yeast culture enters the test dish 1 respectively. The operation process is more convenient, and the efficiency of the test process is improved by performing a synchronous comparative test on two groups of yeast cultures, and the accuracy of the test results is ensured by analyzing the two groups of test results.

[0037] It is worth noting that the adjustment assembly includes a cylinder 25, the barrel end of the cylinder 25 is rotatably arranged on the top of the cover plate 2, and the movable end of the cylinder 25 is rotatably connected to one end of the transmission member 22.

[0038] The other end of the transmission member 22 is rotatably connected to the movable shaft 21, and the movable shaft 21 is rotatably set on the outer wall of the material distribution bin 5. One end of the movable shaft 21 is fixedly connected to the material distribution guide plate 20, and the other end of the movable shaft 21 passes through the outer wall of the material distribution bin 5 and extends to the outside. A through hole communicating with the inside of the material distribution bin 5 is provided on the outer wall of the movable shaft 21, and a bearing is embedded and installed inside the through hole. The movable shaft 21 is embedded inside the bearing, and one end of the movable shaft 21 is located inside the material distribution bin 5 and is fixedly connected to the circumferential outer wall of the material distribution guide plate 20. The other end of the movable shaft 21 extends to the outside of the material distribution bin 5, so that the side of the transmission member 22 close to the movable shaft 21 is fixedly sleeved on the outside of the movable shaft 21 through the mounting hole provided on the surface. The transmission member 22 rotates with the movable shaft 21.

[0039] When feeding the two sides of the partition 17 respectively, the electromagnetic valve of the air guide pipe connected to the cylinder 25 is opened, so that the movable end of the cylinder 25 drives one side of the transmission member 22 to rotate through the hinged connecting shaft 26, so that the other side of the transmission member 22 drives the movable shaft 21 to rotate. The movable shaft 21 drives the material distribution guide plate 20 to slide against the inner wall of the material distribution bin 5, and the yeast culture is introduced into the interior of the two material distribution pipes 6 through the material distribution guide plate 20, so that the two material distribution pipes 6 respectively introduce the yeast culture into the two sides of the partition 17. This makes the operation process more convenient. Through the material distribution introduction of the material distribution guide plate 20, the culture process inside the test dish 1 is compared and analyzed, and the accuracy of the test results is guaranteed by comparing the two groups of experimental results at the same time.

[0040] In addition, one end of the two material distribution pipes 6 is symmetrically embedded in the outer wall of the material distribution bin 5 near the bottom, and the other ends of the two material distribution pipes 6 pass through the cover plate 2 and extend to the inside of the test dish 1. The two material distribution pipes 6 form two conveying pipelines between the material distribution bin 5 and the test dish 1, and the efficiency of the test process is improved through group testing.

[0041] In addition, the material guide assembly includes a spiral material guide 8, which is embedded and installed on the inner wall of the feed barrel 3. The spiral material guide 8 spirals from the top edge of the feed barrel 3 to the arc-shaped bottom edge of the feed barrel 3, and the spiral material guide 8 is fixed to the inner wall of the feed barrel 3. The top of the inner cavity of the feed barrel 3 is embedded with a material storage member 7, and the bottom of the material storage member 7 is fixedly installed with a sealing seat 11, and the spiral material guide 8 is circumferentially fitted to the outer wall of the sealing seat 11. The material storage member 7 is a cylinder, and the diameter of the cylinder is the same as the bottom diameter of the conical material storage member 7.

[0042] One end of the connecting rod 15 is fixedly mounted on the outer wall of the material storage member 7 near the bottom, and the other end of the connecting rod 15 is fixedly mounted on the inner wall of the feeding tube 3 near the top. At this time, the sealing seat 11 fixed on the bottom of the material storage member 7 slides into the center of the spiral material guide member 8, and the sealing seat 11 fits the inner wall of the spiral material guide member 8. When the material is guided into the test dish 1, the yeast culture is put into the feeding tube 3, so that the yeast culture is stored between the feeding tube 3 and the inclined surface of the material storage member 7 through the material storage member 7.

[0043] When guiding the material, the feed barrel 3 is rotated so that the feed barrel 3 drives the spiral material guide 8 fixed on the inner wall to rotate. With the continuous circumferential rotation of the spiral material guide 8, the material between the inner wall of the feed barrel 3 and the inclined surface of the material storage member 7 falls from the bottom of the feed barrel 3 into the inside of the receiving hopper 27 in sequence. Then, the material is introduced into the two test chambers of the test dish 1 in sequence through the two material distribution pipes 6 at the bottom of the receiving hopper 27, ensuring the flow of material input during the yeast culture test. It avoids the material from being blocked during the entry process, thereby ensuring the smoothness, and the amount of material is controlled by rotating the feed barrel 3, thereby ensuring the accuracy of the test results.

[0044] Furthermore, a rotating drive assembly for rotating the feed barrel 3 is provided on the top of the cover plate 2. The rotating drive assembly enables the feed barrel 3 to drive the internal spiral guide 8 to rotate continuously, so that the yeast culture test material passes through the feed barrel 3 and falls into the receiving hopper 27, thereby bringing convenience to the operation process of relevant personnel.

The annular seat 16 is fixed above the cover plate 2 by a plurality of fixed rods 18. The annular seat 16 is rotatably arranged on the outside of the feed barrel 3, and a bearing is fixedly embedded and installed on the inner wall of the annular seat 16. The feed barrel 3 is embedded and installed inside the bearing, and both sides of the feed barrel 3 extend out of the outside of the annular seat 16 on both sides. The feed barrel 3 is a hollow cylinder. A gear 9 is rotatably arranged on the outer wall of the annular seat 16, and teeth 10 are evenly arranged on the outer wall of the feed barrel 3, and the teeth 10 are meshed with the gear 9. The drive motor is fixed on the outer wall of the annular seat 16 by a base. The gear 9 is fixedly sleeved on the outside of the output shaft of the drive motor through a mounting hole opened in the center, and the drive motor is electrically connected to an external power supply through a wire.

[0046] A circle of teeth 10 is arranged on the outer surface of the feed barrel 3 and at a position corresponding to the gear 9. When feeding materials into the receiving hopper 27, the drive motor is connected to the power supply so that the output shaft of the drive motor drives the gear 9 to rotate, and the teeth 10 meshing with the gear 9 drive the feed barrel 3 to rotate inside the annular seat 16, so that the materials fall into the receiving hopper 27 in sequence and evenly, thereby facilitating the operation of the material feeding process.

[0047] The receiving hopper 27 is fixedly arranged between the cover plate 2 and the feed barrel 3. One end of a support rod 28 is evenly fixedly installed on the outer wall of the receiving hopper 27, and the other end of the support rod 28 is respectively fixed on the outer wall of each fixing rod 18, so that the receiving hopper 27 is fixed between the cover plate 2 and the feed barrel 3, ensuring the stability of the material distribution process.

[0048] The bottom of the cover plate 2 is symmetrically provided with heaters 19, and two heaters 19 are respectively placed on both sides of the partition 17. The heater 19 is built with a heating wire, and the heating wire heats the two parts of the inner cavity of the test dish 1 respectively, ensuring the necessary conditions for the yeast culture test process.

[0049] The locking member includes a clamping block 12 and a clamping seat 13, and the clamping seat 13 is fixedly mounted on the top of the outer wall of the test dish 1. The clamping block 12 is fixedly mounted on the side wall of the cover plate 2, and the clamping block 12 is inserted into the inside of the clamping seat 13. When the test dish 1 is sealed, the cover plate 2 is embedded into the top of the test dish 1, and the clamping block 12 is inserted into the inside of the clamping groove opened on the surface of the clamping seat 13 along with the cover plate 2. Then, the clamping seat 13 is fixed by bolts on the surface of the clamping seat 13, thereby ensuring the stability of the connection between the cover plate 2 and the test dish 1, and then ensuring the sealing of the test dish 1 during the test process.

[0050] The present embodiment is a yeast culture production test device, and its working principle is as follows: first, yeast culture is put into the feed barrel 3, so that the yeast culture is stored between the feed barrel 3 and the inclined surface of the material storage member 7 through the material storage member 7. Then, the output shaft of the driving motor drives the gear 9 to rotate, so that the teeth 10 meshing with the gear 9 drive the feed barrel 3 to rotate inside the annular seat 16. As the feed barrel 3 rotates, the spiral guide member 8 causes the material to fall into the inside of the receiving hopper 27 in sequence and uniformly. Then, the movable end of the cylinder 25 drives one side of the transmission member 22 to rotate through the hinged connecting shaft 26, so that the other side of the transmission member 22 drives the movable shaft 21 to rotate, so that the movable shaft 21 drives the material distribution guide plate 20 to slide against the inner wall of the material distribution bin 5. The yeast culture is introduced into the inside of the two material distribution pipes 6 respectively through the material distribution guide plate 20, and then the cover plate 2 is covered on the top of the test dish 1 to perform two groups of tests.
