Description

Technical Field

[0001] This utility model relates to the technical field of liquor fermentation equipment, specifically a solid-state fermentation type liquor fermentation equipment. Background Technology

[0002] Baijiu, a unique distilled spirit in China, uses starchy grains such as sorghum, rice, corn, and wheat as its core raw materials. These raw materials, due to their high starch content and suitable nutritional structure, provide a sufficient material basis for subsequent fermentation. Its brewing relies on yeast (including daqu, xiaoqu, and bran yeast) and starter culture as saccharification and fermentation agents. The rich microbial community and enzyme system in the yeast are key to flavor formation. The production process adopts a unique solid-state fermentation process. First, the starch of the raw materials is gelatinized by steaming and cooking. Then, yeast is added for saccharification, converting the starch into fermentable sugars. Subsequently, it enters a long-term solid-state fermentation stage, allowing microorganisms to fully metabolize and produce flavor substances.

[0003] For example, the patent with authorization announcement number CN223342659U describes a solid-state fermentation device for producing baijiu. After crushing, the first closed baffle between the tank and the filter chamber is removed, and the raw pulp flows into the filter chamber. It is filtered in sequence through a bamboo first filter and a tightly composite mesh second filter to produce raw pulp of different concentrations. After filtration, the second and third closed baffles are inserted to avoid concentration confusion. The filter can also be changed to brew a variety of flavors.

[0004] The existing technology has the following problems: Existing technology separates raw liquor of different concentrations by manually inserting a closed baffle. This manual operation is not only cumbersome, but also significantly reduces work efficiency in continuous production scenarios due to frequent insertion and removal. Furthermore, inconsistent operating force and timing can easily lead to incomplete sealing of the baffle, causing cross-flow and mixing of raw liquors of different concentrations, which directly affects the separation accuracy. Particles remaining on the filter screen can clog the filter screen pores, leading to increased filtration resistance and slower flow rate. Over time, this accumulation can also cause a continuous decline in the filter screen's filtration capacity. In addition, if the residual particles are not cleaned in time, they can easily breed bacteria that contaminate subsequent raw liquors, affecting the quality of the wine. Moreover, cleaning the residue requires stopping the machine, further increasing labor costs and production downtime.

[0005] Based on this, a solid-state fermentation type baijiu fermentation device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0006] The purpose of this invention is to provide a solid-state fermentation type baijiu fermentation device to solve the problems in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A solid-state fermentation type baijiu (Chinese liquor) fermentation device includes a tank body. A rotating shaft is rotatably mounted inside the tank body. Several stirring rollers are fixedly connected to the side of the rotating shaft, with the spacing between the rollers gradually decreasing along the rotating shaft direction. A first rotating motor drives the rotating shaft to rotate and is mounted on the surface of the tank body. A feeding seat is provided at the feeding end of the tank body, and a valve is provided at the discharging port. A filter chamber is connected to the end of the tank body, and several conveying pipes pass through the filter chamber, connecting to a fermentation tank. A water outlet seat is provided on the fermentation tank, with a discharge pool located in the direction of the water outlet. A filtration mechanism is provided inside the filter chamber, including isolation plates. Several isolation plates are provided inside the filter chamber, and a rotating seat is fixedly connected to the surface of each isolation plate. A rotating block is rotatably connected to the rotating seat.

[0008] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: a filter block is fixedly connected to the center of the rotating block, and a sealing block is fixedly connected to the side of the filter block.

[0009] In one alternative: a cleaning seat is provided on the side of the rotating seat, and a conveying roller is rotatably provided inside the cleaning seat.

[0010] In one alternative: several mounting brackets are fixedly connected to the side of the filter chamber, and a second rotating motor is mounted on the mounting bracket, which drives the feed roller to rotate.

[0011] In one alternative: the feed roller is coaxially connected to a first helical gear along the direction of the cleaning seat, a second helical gear is provided on the side of the first helical gear, and the second helical gear is fixedly connected to the closing block.

[0012] In one alternative: the cleaning seat is located outside the filter chamber and connected to the discharge seat, which is connected to the discharge pipe.

[0013] In one alternative: the surface of the feed roller is provided with scrapers.

[0014] In one alternative: the surface of the isolation plate is provided with guide grooves.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The rotating connection between the rotating block and the rotating seat in this utility model provides a structural basis for flexible switching between filtration and isolation states. It is convenient and efficient to operate. When the filter block moves to the outside of the rotating seat, its gradually decreasing mesh size along the vertical direction can perform graded filtration of the raw pulp, accurately separating raw pulp of different concentrations to meet the needs of diversified production for different concentration base materials. After filtration, rotating the rotating block moves the sealing block to the outside of the rotating seat. The sealing block can effectively isolate the graded raw pulp of different concentrations, avoiding mixing and concentration confusion. This ensures that the proportion of raw pulp of each concentration is accurate and controllable during subsequent batching, thereby improving the stability of the final product quality. At the same time, it simplifies the batching process and improves production efficiency.

[0016] 2. The second rotating motor of this utility model serves as the core power source, and a linkage mechanism is formed by driving the material conveying roller to rotate: when the material conveying roller rotates, it synchronously drives the first helical gear. With the help of the helical gear meshing transmission, the first helical gear drives the second helical gear to rotate, thereby driving the sealing block to move synchronously. This realizes efficient power transmission and multi-component coordination. The linkage between filtration / isolation state switching and cleaning operation can be completed without an additional power source, simplifying the equipment structure and reducing energy consumption.

[0017] 3. When the conveying roller of this utility model rotates inside the cleaning seat, its surface scraper can scrape off the raw material particles adhering to the surface of the filter block or sealing block and directionally convey them to the discharge seat. Then, through the cooperation of the discharge pipe and the suction machine, the particles are automatically discharged, which effectively ensures the cleanliness of the surface of the filter / isolation component, avoids residual particles from affecting the subsequent filtration accuracy or isolation effect, and also improves the cleaning efficiency by replacing manual operation with mechanized cleaning, reduces the hygiene risks caused by manual intervention, and further ensures the stability and standardization of the production process.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-3 As shown, a solid-state fermentation type baijiu fermentation device includes a tank 101. A rotating shaft 103 is rotatably mounted inside the tank 101. Several stirring rollers 104 are fixedly connected to the side of the rotating shaft 103, with the spacing between the rollers gradually decreasing along the direction of the rotating shaft 103. A first rotating motor 102 drives the rotating shaft 103 to rotate. The first rotating motor 102 is mounted on the surface of the tank 101. A feeding seat 105 is provided at the feeding end of the tank 101. A valve 106 is provided at the discharge port of the tank 101. A filter chamber 107 is connected to the end of the tank 101. Several conveying pipes 108 pass through the filter chamber 107 and connect to a fermentation tank 109. A water outlet seat 111 is provided on the fermentation tank 109, and a discharge pool 110 is provided in the direction of water discharge from the water outlet seat 111. A filtration mechanism is provided inside the filter chamber 107. The filtration mechanism includes several isolation plates 201 inside the filter chamber 107. A rotating seat 202 is fixedly connected to the surface of the container. The rotating seat 202 is rotatably connected to the rotating block 203. Raw materials are input through the feed seat 105. A water tank is provided inside the tank body 101, and an electric heating wire is provided outside the water tank. The temperature is controlled by a controller. The water tank and the electric heating wire steam the raw materials inside the tank body 101 to gelatinize the starch. The first rotating motor 102 drives the rotating shaft 103 to rotate, and the rotating shaft 103 drives the stirring roller 104 to rotate, breaking the raw material particles. The saccharification and fermentation agent is added to the feeding seat 105 to convert starch into fermentable sugars, providing conditions for fermentation. After fermentation, the valve 106 is opened to connect the tank 101 with the filter chamber 107, and the raw slurry flows into the filter chamber 107. A water pump is installed on the conveying pipe 108. The water pump is started to draw out the raw slurry through the conveying pipe 108 and let it stand in the fermentation tank 109. The water outlet seat 111 is opened, and the settled raw slurry moves through the water outlet seat 111 to the inside of the discharge tank 110 to complete the discharge operation. In one embodiment, such as Figure 3 and Figure 4 As shown, the rotating block 203 is fixedly connected to the filter block 204 in the middle, and the filter block 204 is fixedly connected to the sealing block 205 on the side. The internal space of the filter chamber 107 is divided by the isolation plate 201 to provide conditions for filtering the raw pulp. The rotating block 203 is rotatably connected to the rotating seat 202 to provide conditions for switching the filtration conditions. When the filter block 204 moves to the outside of the rotating seat 202, the filter block 204 filters the raw pulp. The mesh of the filter block 204 gradually decreases in the vertical direction to provide conditions for raw pulp of different concentrations. After filtration, the rotating block 203 is rotated to move the sealing block 205 to the outside of the rotating seat 202 to provide isolation conditions for raw pulp of different concentrations in the sealing block 205 and avoid concentration confusion. Raw pulp of different concentrations is extracted through the conveying pipe 108 to facilitate batching. In one embodiment, such as Figure 4 and Figure 5 As shown, the rotating seat 202 has a cleaning seat 208 on its side, and a conveying roller 209 is rotatably installed inside the cleaning seat 208. When switching between the filter block 204 and the sealing block 205, the cleaning seat 208 rubs the filter block 204 or the sealing block 205. The surface of the cleaning seat 208 is provided with scrapers. The scrapers separate the raw material particles that are stuck to the surface of the filter block 204 or the sealing block 205. The raw material particles are transferred by the rotation of the conveying roller 209, thus providing conditions for cleaning the surface of the filter block 204 or the sealing block 205. In one embodiment, such as Figure 4 and Figure 5 As shown, several mounting brackets 206 are fixedly connected to the side of the filter chamber 107. A second rotating motor 207 is mounted on the mounting bracket 206. The second rotating motor 207 drives the feeding roller 209 to rotate. The mounting bracket 206 provides the installation conditions for the second rotating motor 207 and provides power for the rotation of the feeding roller 209. In one embodiment, such as Figure 4 and Figure 5 As shown, the feeding roller 209 is coaxially connected to the first helical gear 210 along the direction of the cleaning seat 208. The first helical gear 210 has a second helical gear 211 on its side. The second helical gear 211 is fixedly connected to the sealing block 205. By rotating the feeding roller 209, the first helical gear 210 is driven to rotate, the first helical gear 210 is driven to rotate, the second helical gear 211 is driven to rotate, and the second helical gear 211 is driven to rotate. The switching or cleaning operation of filter block 204 or sealing block 205 is adjusted by controlling the rotation direction of feed roller 209. It rotates forward during switching and reverses during cleaning. When switching, feed roller 209 rotates in reverse, and raw material particles remain on the surface of filter block 204 or sealing block 205. In one embodiment, such as Figure 4 and Figure 5 As shown, the cleaning seat 208 is connected to the discharge seat 212 outside the filter chamber 107. The discharge seat 212 is connected to the discharge pipe 213. The raw material particles are transported to the discharge seat 212 by the rotation of the conveying roller 209. The material is then extracted by the material extractor connected to the discharge pipe 213, which facilitates the cleaning operation.

[0026] The above embodiment discloses a solid-state fermentation type liquor fermentation device. The feed seat 105 feeds into the tank 101. Under the control of a controller, an electric heating wire outside the water tank inside the tank 101, in conjunction with the water tank, steams the raw materials to gelatinize the starch. A first rotating motor 102 drives a rotating shaft 103, causing the spacing of the stirring rollers 104 to gradually decrease along the direction of the rotating shaft 103, thus crushing the raw material particles. A saccharifying and fermenting agent is then added through the feed seat 105 to convert the starch into fermentable sugars. After fermentation, the valve 106 is opened, and the raw liquor flows into a filter chamber 107 connected to the end of the tank 101. Inside the filter chamber 107, a partition plate 201 divides the space. The filter block 204, fixed in the middle of the rotating block 203 connected to the rotating seat 202 on its surface, has a mesh size that gradually decreases vertically to filter the raw liquor. After filtration, the rotating block 203 is rotated, causing the sealing block 205 to move outside the rotating seat 202. Different concentrations of raw pulp are isolated. The second rotating motor 207 on the mounting bracket 206 on the side of the filter chamber 107 drives the conveying roller 209 in the cleaning seat 208 to rotate. When the scraper on the surface of the conveying roller 209 switches between the filter block 204 and the sealing block 205, it separates the raw material particles adhering to the surface of the two and transfers them. The first helical gear 210 coaxially connected to the conveying roller 209 drives the second helical gear 211 to rotate. The rotation of the second helical gear 211 drives the sealing block 205 to rotate. The rotation direction of the conveying roller 209 is controlled to adjust the switching or cleaning operation. The cleaned raw material particles are discharged through the discharge seat 212 and discharge pipe 213 connected to the cleaning seat 208. The filtered raw pulp is pumped to the fermentation tank 109 through the conveying pipe 108 for settling. After settling, the water outlet seat 111 of the fermentation tank 109 is opened, and the raw pulp flows into the discharge tank 110 to complete the discharge. The guide groove on the surface of the isolation plate 201 assists the flow of raw pulp.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
