Description

Technical Field

[0001] This utility model relates to the technical field of yeast preparation, and in particular to a weighing device for raw materials used in yeast preparation. Background Technology

[0002] The preparation of yeast starter (or koji) refers to the process of selecting raw materials, inoculating them with microorganisms, and cultivating them under suitable conditions to produce a fermentation agent rich in various enzymes and active microorganisms. It is a crucial step in brewing, converting the starch in grains into sugar, which is then further fermented to produce alcohol and flavor compounds. Yeast starter typically uses rice, wheat, beans, etc., as raw materials. After steaming and cooling, it is inoculated with various microorganisms such as Aspergillus and yeast. Cultivation is then carried out under controlled temperature and humidity, allowing the microorganisms to multiply rapidly and produce a rich enzyme system. These enzymes not only improve fermentation efficiency during the brewing process but also impart unique aromas and flavors to the liquor, forming a vital foundation for determining the quality and style of the liquor.

[0003] In the process of preparing yeast starter, weighing the raw materials is a crucial step in ensuring accurate proportions. However, most commonly used raw material weighing devices employ a fixed feeding structure, where the raw materials fall directly into the tank through a fixed discharge port at the top. Due to the fixed discharge location and lack of dispersion measures, the raw materials tend to concentrate in a localized area of ​​the tank due to gravity, gradually forming an accumulation. This accumulation not only prevents the weighing sensor from accurately sensing the actual weight of the raw materials, causing weighing errors and affecting the stability of the yeast starter proportions, but it can also lead to reduced efficiency in subsequent mixing processes due to uneven distribution of raw materials, sometimes even requiring manual intervention to level them. This increases operational complexity and production costs, making it difficult to meet the precision and continuity requirements of modern yeast starter production. Utility Model Content

[0004] In view of the problems that existing weighing devices for raw materials used in yeast preparation cause raw material accumulation due to fixed material feeding, resulting in inaccurate weighing, affecting subsequent processes and increasing operating costs, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a weighing device for raw materials used in yeast preparation, which aims to solve the problem that existing weighing devices for raw materials used in yeast preparation cause raw material accumulation due to fixed material feeding, resulting in inaccurate weighing, affecting subsequent processes, and increasing operating costs.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a raw material weighing device for preparing yeast, including a weighing mechanism, a feeding mechanism and a dispensing mechanism, the weighing mechanism including a weighing container, the feeding mechanism including a feeding pipe installed above the weighing container and a dispensing pipe installed below the weighing container, a first feeding paddle being rotatably installed inside the feeding pipe, and a second feeding paddle being rotatably installed inside the dispensing pipe; The bulk material handling mechanism includes a rotating pipe rotatably mounted on one side of the lower surface of the feed pipe, a rotating cover rotatably mounted on the upper surface of the weighing container, a feed inlet penetrating through the surface of the rotating cover, an elastic telescopic pipe installed between the feed inlet and the rotating pipe, a stirring rod fixedly mounted on the lower surface of the rotating cover, and a scraper movably mounted on the outer side of the stirring rod via a spring structure.

[0007] In a preferred embodiment of the raw material weighing device for preparing yeast according to this utility model, the weighing container is fixedly installed on the inner side of the outer frame, and a base frame is fixedly installed on the lower surface of the outer frame.

[0008] In a preferred embodiment of the raw material weighing device for yeast preparation described in this utility model, the first feeding paddle is driven and installed at the output end of the first motor.

[0009] In a preferred embodiment of the raw material weighing device for yeast preparation described in this utility model, the second feeding paddle is driven and installed at the output end of the second motor.

[0010] In a preferred embodiment of the raw material weighing device for yeast preparation described in this utility model, a drive motor is fixedly installed on the upper part of one side of the outer frame, and a drive gear is driven at the output end of the drive motor.

[0011] In a preferred embodiment of the raw material weighing device for preparing yeast according to the present invention, a toothed block is fixedly installed on the side surface of the rotating cover, and the rotating cover meshes with the driving gear through the toothed block.

[0012] In a preferred embodiment of the raw material weighing device for yeast preparation described in this utility model, a number of weighing sensors are installed between the outer side of the weighing container and the inner side of the outer frame.

[0013] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model, through its material distribution mechanism, allows raw materials to enter the weighing container via the inlet and outlet mechanism. A drive motor rotates the active gear, which in turn rotates the rotating cover via a gear block. The rotating cover then rotates the elastic telescopic tube in the upper part of the weighing container, ensuring the raw materials are evenly distributed inside. Simultaneously, the rotating cover rotates the stirring rod, further evenly spreading the raw materials within the container. This effectively solves the problem of localized accumulation of raw materials within the weighing container, ensuring uniform force on the weighing sensor and significantly improving weighing accuracy and proportioning precision. This provides a reliable guarantee for the stability of subsequent yeast preparation processes and product quality.

[0014] 2. This utility model, through its feeding and weighing mechanisms, uses weighing sensors installed on the outside of the weighing container and the inside of the outer frame to detect changes in the weight of the raw materials inside the weighing container in real time, thereby achieving the purpose of weighing. Simultaneously, a first motor drives a first feeding paddle to rotate, and a second motor drives a second feeding paddle to rotate, realizing the purpose of raw materials entering and exiting the weighing container. Through the integrated feeding and weighing mechanism, the automatic and precise feeding and discharging of raw materials is achieved. Combined with real-time weight monitoring, this not only significantly improves the automation and efficiency of the weighing operation, but also reduces manual intervention, ensures the continuity and stability of the production process, and effectively reduces operating costs.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Example 1 Reference Figures 1-2This is the first embodiment of the present invention, which provides a weighing device for raw materials used in the preparation of yeast starter. This weighing device for raw materials used in the preparation of yeast starter includes a weighing mechanism 1, a feeding mechanism 2, and a dispensing mechanism 3. The weighing mechanism 1 includes a weighing container 103. The feeding mechanism 2 includes a feeding pipe 201 installed above the weighing container 103 and a dispensing pipe 204 installed below the weighing container 103. A first feeding paddle 203 is rotatably installed inside the feeding pipe 201, and a second feeding paddle 206 is rotatably installed inside the dispensing pipe 204.

[0019] The weighing container 103 is fixedly installed on the inner side of the outer frame 102, and the base frame 101 is fixedly installed on the lower surface of the outer frame 102.

[0020] The first feed paddle 203 is driven and installed at the output end of the first motor 202.

[0021] The second feed paddle 206 is driven and installed at the output end of the second motor 205.

[0022] Several sets of weighing sensors are installed between the outer side of the weighing container 103 and the inner side of the outer frame 102.

[0023] During operation, the raw materials first enter the weighing container 103 through the feed pipe 201. At this time, the first motor 202 starts, driving the first feeding paddle 203 to rotate, continuously and stably pushing the raw materials into the weighing container 103. During the process of raw material entering, several sets of weighing sensors installed between the outside of the weighing container 103 and the inside of the outer frame 102 will sense the weight change of the weighing container 103 in real time and transmit the data to the control system. When the weight reaches the preset value, the first motor 202 stops working, the feeding process ends, and after weighing is completed, the second motor 205 starts, driving the second feeding paddle 206 to rotate, pushing the precisely proportioned raw materials in the weighing container 103 out of the discharge pipe 204 and sending them to the next process. Throughout the process, the base frame 101 provides stable support for the entire device, while the outer frame 102 protects and fixes the weighing container 103, ensuring that the weighing sensors work accurately in an environment without external interference, realizing the fully automated operation from automatic feeding, accurate weighing to automatic discharge.

[0024] Example 2 Reference Figures 2-4This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the bulk material mechanism 3 includes a rotating pipe 301 rotatably installed on one side of the lower surface of the feed pipe 201, a rotating cover 305 rotatably installed on the upper surface of the weighing container 103, a feed inlet penetrating through the surface of the rotating cover 305, an elastic telescopic pipe 302 installed between the feed inlet and the rotating pipe 301, a stirring rod 307 fixedly installed on the lower surface of the rotating cover 305, and a scraper 309 movably installed on the outside of the stirring rod 307 through a spring structure 308.

[0025] A drive motor 303 is fixedly installed on the upper part of one side of the outer frame 102, and a drive gear 304 is installed at the output end of the drive motor 303.

[0026] A toothed block 306 is fixedly installed on the side surface of the rotating cover 305, and the rotating cover 305 meshes with the drive gear 304 through the toothed block 306.

[0027] During use, when raw materials enter through the feed pipe 201, the drive motor 303 starts synchronously, driving the drive gear 304 to rotate. The drive gear 304 meshes with the toothed block 306 on the side surface of the rotating cover 305, driving the rotating cover 305 to rotate on the upper surface of the weighing container 103. The rotation of the rotating cover 305 drives the rotating tube 301 below to rotate together through the elastic telescopic tube 302, so that the raw materials falling from the feed pipe 201 undergo circular motion with the rotating tube 301 before entering the weighing container 103. The raw materials are evenly distributed inside the weighing container 103. At the same time, the stirring rod 307, which is fixed on the lower surface of the rotating cover 305, rotates to further stir the falling raw materials, making them spread more evenly. In addition, the scraper 309, which is movably installed on the outside of the stirring rod 307 through the spring structure 308, will adhere to the inner wall of the weighing container 103 under the action of centrifugal force and spring, effectively preventing the raw materials from sticking together and ensuring that all raw materials can be effectively stirred and weighed. This further ensures the uniformity of the force on the weighing sensor and the accuracy of the measurement results.

[0028] The remaining structure is the same as that in Example 1.

[0029] Based on embodiments 1-2, the working principle of this utility model is as follows: First, the first motor 202 starts, driving the first feeding paddle 203 in the feeding pipe 201 to rotate, stably pushing the raw material into the weighing container 103. Simultaneously, the dispersing mechanism 3 begins to work in coordination, driving the drive motor 303 to rotate the drive gear 304, which in turn drives the rotating cover 305 to rotate through the meshing of the toothed block 306. This, in turn, causes the elastic telescopic tube 302 and the rotating tube 301 connected to it to perform circular motion on the upper part of the weighing container 103, ensuring that the raw material is evenly dispersed during its descent. At the same time, the stirring rod 307 below the rotating cover 305 rotates accordingly, performing secondary stirring on the falling raw material. The scraper rod 309, connected by the spring structure 308, adheres to the inner wall of the container to prevent the raw material from sticking together, ensuring its proper distribution within the container. The material is evenly distributed inside the container. As the raw material continuously enters, the weighing sensor between the outer side of the weighing container 103 and the inner side of the outer frame 102 monitors the weight change in real time and feeds the data back to the control system. When the preset weight is reached, the first motor 202 and the drive motor 303 stop simultaneously, and the feeding and dispersing process ends. Subsequently, the second motor 205 starts, driving the second feeding paddle 206 in the discharge pipe 204 to rotate, completely discharging the accurately weighed and evenly mixed raw material from the weighing container 103 and sending it to the next production stage. The entire process, through the integrated feeding and weighing system, combined with the dynamic dispersing mechanism 3, realizes continuous and automated operation from automatic feeding, uniform dispersion, accurate weighing to automatic discharge, effectively solving the problem of raw material accumulation and significantly improving weighing accuracy and production efficiency.
