Abstract
Description
Technical Field
[0001] This utility model relates to the field of yeast culture production technology, specifically a quantitative yeast culture addition device that facilitates precise addition of nutrients. Background Technology
[0002] In the production of yeast cultures, nutrients are the core factors determining yeast growth rate, biomass yield, metabolic activity, and final product quality. Different types of nutrients directly affect production efficiency and product quality by meeting the yeast's energy requirements, structural synthesis, metabolic regulation, and other key physiological processes.
[0003] The following problems were found in the relevant technology: the nutrients in yeast culture are divided into solid and liquid components. Solid nutrients (such as sugars and nitrogen powders) and liquid nutrients (such as vitamin solutions and mineral solutions) are prone to sharing the same channel during the addition process, which can lead to residual solid nutrients clumping and blocking the channel, or liquid nutrients mixing with solid nutrients in advance and causing a chemical reaction that destroys the activity of the nutrients and affects the absorption effect of yeast. The residue left in the channel after mixing can affect the amount added. To address these issues, we have proposed a quantitative yeast culture addition device that facilitates precise addition of nutrients.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background section of this application, and therefore may include prior art information that does not constitute prior art information known to those skilled in the art. Utility Model Content
[0005] This utility model aims to solve at least one of the technical problems existing in the prior art or related technologies. To address the issue of quantitative nutrient addition in the prior art, this utility model provides a quantitative yeast culture additive device that facilitates precise nutrient addition. It employs a combination of a solid-liquid independent addition structure and a quantitative addition structure to ensure the quality of the yeast culture. The specific technical solution is as follows: A quantitative yeast culture addition device for precise nutrient dosing includes a support frame. Solid nutrient storage cylinders and liquid nutrient storage cylinders are fixed at both ends of the support frame. A three-way feed pipe, connected to the solid and liquid nutrient storage cylinders, is fixed to the top of the support frame. The three-way feed pipe has an internal dry-wet separation structure for switching between solid and liquid independent channels. Both the solid and liquid nutrient storage cylinders are equipped with a quantitative monitoring discharge structure. A docking seat is rotatably connected to the bottom of the support frame. A quick-assembly frame is located below the docking seat and is connected to the docking seat via a displacement component.
[0006] In the above technical solution, the dry and wet separation structure includes a partition plate embedded in the middle of the inner cavity of the three-way feed pipe, a feed hopper fixedly connected to the top of the three-way feed pipe, a channel switching plate rotatably disposed on the top of the partition plate and attached to the inner wall of the feed hopper, and an angle adjustment component that drives the channel switching plate to rotate is disposed on the outer wall of the three-way feed pipe.
[0007] The angle adjustment component includes a cylinder rotatably mounted on the outer wall of the three-way feed pipe. The movable end of the cylinder is rotatably connected to a transmission component. A rotating shaft is rotatably mounted on the inner wall of the feed hopper. The transmission component and the channel switching plate are both sleeved on the outside of the rotating shaft.
[0008] The displacement component includes a lead screw rotatably mounted on the quick-assembly frame, and the outer wall of the lead screw is threadedly connected to a movable seat that is fixedly connected to the docking seat.
[0009] The quick-assembly frame is fixed with a guide rail parallel to the lead screw, and the bottom of the docking seat is fixed with a slider that is slidably disposed on the guide rail.
[0010] The inner wall of the rotating seat is evenly provided with teeth in the circumferential direction, and the outer wall of the docking seat is rotatably provided with a drive gear that meshes with the teeth.
[0011] The quantitative monitoring discharge structure includes solenoid valves installed at the discharge ports of the solid nutrient storage tank and the liquid nutrient storage tank, and a level sensor connected to the solenoid valve is installed on the solid nutrient storage tank, and a level sensor connected to the solenoid valve is installed on the liquid nutrient storage tank.
[0012] The bottom of the support frame is fixedly connected to a rotating seat, the docking seat is rotatably disposed inside the rotating seat, and wear-reducing components are evenly arranged circumferentially between the docking seat and the rotating seat.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By using a cylinder to drive the channel switching plate, the solid-liquid nutrient addition can be switched with one click without the need for manual replacement of the feeding parts, thus improving operational efficiency and reducing the risk of contamination from manual contact.
[0014] Second, the entire process requires no manual intervention. The controller automatically completes the closed-loop control of "monitoring - signal transmission - solenoid valve opening and closing", which significantly reduces quantitative error and meets the strict requirements of nutrient concentration for refined yeast cultivation.
[0015] Third, this design fundamentally eliminates the residual mixing of solid and liquid nutrients in the channel, avoids nutrient failure or channel blockage caused by chemical reactions, and ensures the purity and activity of nutrient components. Attached Figure Description

Detailed Implementation
[0017] 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.
[0018] The following are specific implementation cases and appendices. Figure 1-5 The present invention will be further described below, but the present invention is not limited to these embodiments.
[0019] A quantitative yeast culture additive device for precise nutrient addition includes a support frame 1, with a solid nutrient storage cylinder 2 and a liquid nutrient storage cylinder 3 fixed at both ends of the support frame 1. A three-way feed pipe 4, connected to the solid nutrient storage cylinder 2 and the liquid nutrient storage cylinder 3, is fixed to the top of the support frame 1. The three-way feed pipe 4 has a dry-wet separation structure that allows switching between solid and liquid independent channels. The dry-wet separation structure switches the two channels of the three-way feed pipe 4 open and closed. When liquid nutrients are added, the solid channel is closed; when solid nutrients are added, the liquid channel is closed, forming two independent dry-wet channels. This avoids mixing and interference, resulting in more precise nutrient addition.
[0020] Both the solid nutrient storage tank 2 and the liquid nutrient storage tank 3 are equipped with solenoid valves 5 at their outlets. A level sensor 6 connected to the solenoid valve 5 is installed on the solid nutrient storage tank 2, and a level sensor 7 connected to the solenoid valve 5 is installed on the top of the liquid nutrient storage tank 3. The probe of the level sensor 7 is pulled by a lead wire introduced into the liquid nutrient storage tank 3 from the top, causing the probe of the level sensor 7 to float inside the liquid nutrient storage tank 4. Both the solid nutrient storage tank 2 and the liquid nutrient storage tank 3 have independent solenoid valves 5. After receiving signals from the level sensor 6 and the level sensor 7 respectively, the solenoid valves 5 on the solid nutrient storage tank 2 and the liquid nutrient storage tank 3 are driven to open and close by a controller, thereby quantitatively adding nutrients.
[0021] The dry-wet separation structure includes a partition 8 embedded in the middle of the inner cavity of the three-way feed pipe 4. The partition 8 is fixed longitudinally inside the three-way feed pipe 4, dividing the longitudinal channel of the three-way feed pipe 4 into two spaces, each space being connected to independent channels on both sides. A feed hopper 9 is fixedly connected to the top of the three-way feed pipe 4. A channel switching plate 10, which fits against the inner wall of the feed hopper 9, is rotatably mounted on the top of the partition 8. An angle adjustment component that drives the channel switching plate 10 to rotate is provided on the outer wall of the three-way feed pipe 4.
[0022] The channel switching plate 10 corresponds to the shape of the inner wall of the feeding hopper 9, so that the channel switching plate 10 fits against the inner wall of the feeding hopper 9 and rotates. The angle adjustment structure makes the channel switching plate 10 rotate inside the feeding hopper 9, so that after the feeding hopper 9 is tilted, the input nutrients are introduced into the channel on the corresponding side.
[0023] It is worth noting that the angle adjustment mechanism includes a cylinder 11 rotatably mounted on the outer wall of the three-way feed pipe 4. The movable end of the cylinder 11 is rotatably connected to a transmission component 12. A rotating shaft 13 is rotatably mounted on the inner wall of the feed hopper 9. Both the transmission component 12 and the channel switching plate 10 are sleeved on the outside of the rotating shaft 13. Both ends of the rotating shaft 13 extend out of the outside of the three-way feed pipe 4. One end of the transmission component 12 is fixedly sleeved on the outer wall of the rotating shaft 13 located outside the three-way feed pipe 4 through an opening in the mounting hole. The other end of the transmission component 12 and the movable end of the cylinder 11 are simultaneously movably sleeved on the outside of the same shaft.
[0024] A rotating seat 14 is fixedly connected to the bottom of the support frame 1. A docking seat 15 is rotatably connected inside the rotating seat 14. A quick-assembly frame 16 is provided below the docking seat 15, and the quick-assembly frame 16 is connected to the docking seat 15 through a displacement member.
[0025] The displacement component causes the docking seat 15 to move, thereby adjusting the position of the solid nutrient storage cylinder 2 and the liquid nutrient storage cylinder 3. This allows the solid nutrient storage cylinder 2 and the liquid nutrient storage cylinder 3 to adjust their addition positions during the addition of nutrients, enabling more accurate addition of nutrients to the yeast culture.
[0026] In addition, the displacement component includes a lead screw 17 rotatably mounted on the quick-assembly frame 16, and a movable seat 18 that is fixedly connected to the docking seat 15 is threaded onto the outer wall of the lead screw 17. Fixed seats are installed on both sides of the bottom of the quick-assembly frame 16, and the lead screw 17 rotates between the two fixed seats. The motor is fixed on one of the fixed seats by a cover, and the output shaft of the motor passes through the fixed seat and is fixedly connected to the corresponding end of the lead screw 17.
[0027] After the motor is connected to the power supply, the output shaft of the motor drives the lead screw 17 to rotate, which causes the movable seat 18, which is threadedly connected to the lead screw 17, to move the docking seat 15.
[0028] The quick-assembly bracket 16 is fixed with a guide rail 19 parallel to the lead screw 17, and the bottom of the docking seat 15 is fixed with a slider 20 that is slidably disposed on the guide rail 19.
[0029] The guide rail 19, which is parallel to the lead screw 17, allows the docking seat 15 to move while simultaneously driving the slider 20 to slide on the guide rail 19. This ensures the stability of the docking seat 15 during movement, prevents positional deviation, and guarantees the accuracy of the adjustment direction.
[0030] In addition, the inner wall of the rotating seat 14 is evenly provided with teeth 21, and the outer wall of the docking seat 15 is rotatably provided with a drive gear 22 that meshes with the teeth 21. The rotating seat 14 is fitted onto the outside of the docking seat 15 through a groove opened at the bottom. The inner wall of the groove of the rotating seat 14 is provided with a ring of teeth 21. The motor is fixed to the outer wall of the docking seat 15 by a frame, and the drive gear 22 is fixedly sleeved on the outer wall of the motor output shaft through a central mounting hole.
[0031] After the motor is connected to the power supply, the output shaft of the motor drives the drive gear 22 to rotate, which in turn drives the rotating seat 14 to rotate, thereby adjusting the position of the solid nutrient storage cylinder 2 and the liquid nutrient storage cylinder 3.
[0032] Furthermore, wear-reducing components 23 are evenly arranged circumferentially between the docking seat 15 and the rotating seat 14. A base is fixedly installed on the top of the inner wall of the rotating seat 14. The wear-reducing components 23 can be ball bearings. A circumferentially evenly spaced movable groove is formed on the outer wall of the base, and a circumferentially spaced sliding groove is formed on the outer wall of the docking seat 15. The wear-reducing components 23 are movably embedded in the movable cavity formed by the sliding groove and each movable groove. The stability of the rotating seat 14 during rotation is ensured by the wear-reducing components 23.
[0033] The three-way feed pipe 4 is a Y-shaped channel. The main channel is vertically fixed to the top of the support frame 1. The two branch pipes of the three-way feed pipe 4 are connected to the solid nutrient storage tank 2 and the liquid nutrient storage tank 3, respectively.
