Description

Technical Field

[0001] This utility model relates to the field of fermentation fermentation technology, and in particular to a rotary container fermentation device for spreading and cooling fermented mash. Background Technology

[0002] In the traditional brewing process of baijiu, "cooling" is a crucial step. Its core task is to rapidly and evenly cool the distilled mash, which is at a high temperature (usually above 90°C), to a low temperature (below 20°C) suitable for microbial fermentation. The efficiency and quality of this process directly affect the success or failure of subsequent fermentation and the flavor of the base liquor.

[0003] Currently, the vast majority of wineries still use fixed cooling beds (or "cooling beds") as their primary cooling equipment. This equipment is typically a large, rectangular, shallow bed with a stirring and turning mechanism on top. However, this traditional equipment has revealed several increasingly prominent problems in practical application, making it difficult to meet the higher requirements of modern winemaking in terms of hygiene, efficiency, and energy consumption: 1. Significant hygiene risks and high risk of contamination by miscellaneous bacteria: Fixed spreading beds have an open structure, are large in size, and have many internal corners and crevices. After one batch of fermentation is completed, the viscous mash easily adheres to the bed walls, stirring blades, and corners, making cleaning laborious and difficult to thoroughly. The residual mash becomes a breeding ground for miscellaneous bacteria, greatly increasing the risk of contamination of the next batch of material, posing a continuous threat to the quality stability and purity of the liquor. 2. Large footprint and low space utilization: To meet the spreading requirements of single or even multiple steamers of material, the spreading and drying beds typically require a huge surface area. This not only occupies valuable workshop space, resulting in low space utilization, but also limits the compact layout of the production line and further capacity expansion. This problem is particularly challenging for older plants planning technological upgrades or capacity expansion. 3. Poor process matching and difficulty in ensuring uniformity of koji addition: The traditional spreading and cooling operation mode is "spreading and cooling the whole steamer in stages," that is, a whole steamer of hot mash is spread out on the cooling bed, and during the slow cooling process, the operator needs to add koji powder manually in stages and continuously. This method of "cooling and adding koji at the same time" is very likely to cause a mismatch between the amount of koji powder added and the actual cooling amount of the mash, and it is difficult to achieve uniform distribution of koji powder in the whole steamer. This is fundamentally contrary to the "whole steamer and batch" refined management concept pursued by modern brewing technology, affecting the synchronicity of fermentation start and the uniformity of the final mash quality; 4. High energy consumption and cooling efficiency need improvement: On fixed cooling beds, large-volume fans are usually required to blow air across the entire bed surface to achieve cooling. Because the bed surface is stationary, airflow tends to pass through paths with low resistance, leading to uneven cooling and a "short-circuit" phenomenon. To achieve the required final temperature, it is often necessary to extend the blowing time or increase the air volume, resulting in energy waste. In summary, existing fixed cooling beds have significant shortcomings in terms of hygiene, space requirements, process adaptability, and energy consumption. Therefore, developing a new type of cooling device that can adapt to whole-boiler operations, achieve automated control, is easy to clean, and is energy-efficient has become an urgent need to promote the upgrading of baijiu brewing equipment and improve the industry's production level.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is: a rotary container steaming and cooling device, including a mounting frame, on which a rotatable support frame is mounted via a bearing mechanism; the upper part of the rotatable support frame is inclinedly provided with a rotary container shell with an upward opening and capable of axial rotation, and a plurality of ventilation holes are evenly distributed on the lower side wall of the rotary container shell, and the lower part of the rotatable support frame is provided with an air chamber that partially covers the lower outer wall of the rotary container shell, and the air chamber and the outer wall of the rotary container shell are in a sliding sealing fit; The rotatable support frame is equipped with a centrifugal fan whose air outlet is connected to the air chamber; the rotatable support frame is also equipped with a spreading rotary motor for driving the axial rotation of the rotating container shell; the mounting frame is also equipped with a rotating discharge motor for driving the rotatable support frame, the rotating container shell and the air chamber to rotate together relative to the mounting frame.

[0006] As a further improvement of this utility model, the inner wall of the rotary container shell is provided with a mixing structure for lifting and mixing materials.

[0007] As a further improvement of this utility model, the drying rotary motor is a variable frequency geared motor.

[0008] As a further improvement of this utility model, an elastic sealing element is provided between the air chamber and the rotating container shell.

[0009] As a further improvement of this utility model, the upper part of the flip-up support frame is provided with a support roller for auxiliary support of the rotating container shell, and the outer wall of the rotating container shell is provided with an annular track arranged around its axis and rolling in cooperation with the support roller.

[0010] As a further improvement of this utility model, the shape of the rotating container shell is spherical.

[0012] As a further improvement of this utility model, the shape of the rotating container shell is cylindrical.

[0013] As a further improvement of this utility model, the shape of the rotating container shell is frustoconical.

[0014] As a further improvement of this utility model, a maintenance manhole is provided at the bottom of the air chamber.

[0015] Beneficial effects Compared with the prior art, the advantages of the rotary container steaming and cooling device of this utility model are as follows: 1. Fundamentally eliminates unsanitary corners and effectively reduces the risk of contamination by miscellaneous bacteria: This invention uses a closed or semi-closed rotary container shell as the spreading carrier, replacing the traditional open spreading bed. The mash completes all processes within the container, reducing cross-contamination with the workshop environment. After operation, the rotary container shell can be easily rinsed and steam-sterilized, solving the persistent problems of difficult cleaning and easy residue buildup in traditional equipment, providing reliable hygiene assurance for the brewing of high-quality baijiu; 2. Vertical layout greatly improves space utilization: This invention transforms traditional planar drying into a three-dimensional, rotating container-based drying system. The equipment has a compact structure, significantly reducing the floor space required. Compared with fixed drying beds of the same processing capacity, the floor space can be reduced by more than 50%, greatly improving the space utilization efficiency of the production workshop. It is particularly suitable for the renovation of old factories or the construction of new workshops with limited space. 3. Perfectly compatible with the "whole-boiler" process, ensuring uniform addition of koji and homogeneous fermentation: This invention achieves true batch processing with "whole-boiler in, whole-boiler out." The hot mash from a single distillation is fed into a rotating container shell, where cooling, koji addition, and mixing are completed. When adding koji powder, the rotating container shell rotates rapidly, utilizing its built-in mixing structure to ensure thorough and uniform mixing of the koji powder with the whole-boiler mash in a short time. This fundamentally solves the problems of imbalanced koji-mash ratio and uneven mixing caused by traditional timed cooling and continuous koji addition, ensuring the synchronicity and consistency of fermentation start-up for the whole-boiler materials and improving the stability of the base liquor quality. 4. Achieve precise directional airflow and significantly reduce energy consumption for spreading and cooling: This invention forms a bottom-up directional cooling airflow path through the ventilation holes in the bottom air chamber and the rotating container shell. Driven by a fan, the cooling air penetrates the mash layer in a concentrated manner, avoiding the "short-circuit" phenomenon of airflow on the fixed bed surface. Simultaneously, the slow rotation of the rotating container shell continuously tumbles the mash, ensuring that every part is evenly exposed to the cold air, resulting in high heat exchange efficiency. Compared with traditional spreading and cooling beds, this invention can save 20%-30% of fan energy consumption while achieving the same cooling effect, realizing high efficiency and energy saving.

[0016] 5. High degree of automation, significantly reducing labor intensity and labor costs: This device integrates turning and spreading, forced-air cooling, rotary addition of yeast, mixing, and turning and discharging into one unit. The entire process can be automatically completed by program control. Operators only need to monitor and input commands, without having to perform heavy manual labor such as turning and cleaning. A single person can manage multiple machines, effectively reducing labor intensity and saving labor costs, which is in line with the development trend of industrial automation.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; of course, they can also refer to a mechanical connection or an electrical connection; furthermore, they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0024] Example: The specific embodiments of this utility model are as follows: Figure 1-5 As shown, a rotary container steaming and cooling device mainly includes an installation frame 4, a tiltable support frame 5, a rotary container shell 1, an air chamber 3, a centrifugal fan 6, a cooling rotation motor 7, and a tilting discharge motor 2.

[0025] The mounting frame 4 serves as the basic support structure for the entire device, and a tiltable support frame 5 is mounted on it via a bearing mechanism. A rotating container shell 1 is tilted at the top of the tiltable support frame 5, with its opening facing upwards to receive the whole batch of hot mash transported by the overhead crane. The rotating container shell 1 is mounted on the top of the tiltable support frame 5 and can rotate around its own axis. Specifically, rollers are provided on the top of the tiltable support frame 5, and a circular track is correspondingly provided on the outer wall of the rotating container shell 1, arranged around its axis. The rollers and the circular track roll in cooperation, jointly bearing the weight of the rotating container shell 1 and ensuring its smooth rotation.

[0026] Several ventilation holes are evenly distributed on the lower side wall of the rotating container shell 1. The air chamber 3 is fixedly installed on the lower part of the tiltable support frame 5, and its shape is a semi-enclosed structure, partially covering the area around the ventilation holes on the lower part of the rotating container shell 1. A sliding seal is used between the air chamber 3 and the outer wall of the rotating container shell 1, and wear-resistant elastic sealing elements, such as polymer sealing strips, are provided to ensure that the air chamber 3 maintains a relatively sealed state when the rotating container shell 1 rotates, significantly reducing the air leakage rate. A maintenance manhole can also be provided at the bottom of the air chamber 3 for easy daily maintenance and cleaning.

[0027] Centrifugal fan 6 is fixedly mounted on the tiltable support frame 5, and its outlet is connected to the interior of air chamber 3 via an air duct. In this embodiment, the spreading rotation motor 7 is a variable frequency geared motor, which is fixed on the tiltable support frame 5, and its output end is connected to the rotating shaft on the lower outer wall of the rotary container shell 1 through a coupling or other transmission components, for driving the rotary container shell 1 to rotate axially. At the same time, the tilting discharge motor 2 is a geared motor, which is fixed on the mounting frame 4, and its output end is connected to the tiltable support frame 5 through a chain or linkage mechanism, for driving the entire tiltable support frame 5 and all the components it carries—including the rotary container shell 1, air chamber 3, centrifugal fan 6, and spreading rotation motor 7—to rotate around the bearing mechanism axis on the mounting frame 4.

[0028] like Figure 5 As shown, a stirring structure—such as a lifting plate or ribs—is preferably provided on the inner wall of the rotary container shell 1. The shape of the rotary container shell 1 can be designed as a spherical, ellipsoidal, cylindrical, or frustum-shaped rotary structure according to actual needs.

[0029] The specific working process of this device is as follows: Material receiving stage: The tilting discharge motor 2 drives the tilting support frame 5 to adjust the opening of the rotary container shell 1 to a vertically upward position. The overhead crane pours a whole batch of hot mash after distillation into the rotary container shell 1.

[0030] During the cooling and spreading stage: The rotating discharge motor 2 activates, tilting the tumbler support frame 5 at a certain angle, allowing the mash to spread out within the rotating container shell 1. Subsequently, the centrifugal fan 6 and the cooling and spreading motor 7 start simultaneously. The centrifugal fan 6 blows natural air into the air chamber 3, and under air pressure, the airflow is forced and evenly passed through the ventilation holes at the bottom of the rotating container shell 1, penetrating the mash layer from bottom to top. At the same time, the cooling and spreading motor 7 drives the rotating container shell 1 to rotate slowly and uniformly at a low speed. The stirring structure on the inner wall continuously lifts and turns the mash at the bottom to the top, ensuring that all the mash comes into full and even contact with the cold air, achieving efficient and uniform cooling through evaporation and mass transfer. This process achieves precise directional airflow, avoids airflow short-circuiting, and the turning ensures uniform heat exchange, thus significantly reducing the energy consumption of cooling and spreading.

[0031] Adding koji and mixing stage: Once the temperature of the mash drops to the set value, the rotation is paused. All the pre-weighed koji powder needed for the entire batch is added to the rotating container shell 1 at once, either manually or using specialized equipment. Then, the spreading and cooling motor 7 switches to high-speed mode, driving the rotating container shell 1 to rotate rapidly. Under the action of the inner wall mixing structure, the koji powder and the entire batch of mash are vigorously and thoroughly mixed evenly in a short time. This batch operation of "cooling the entire batch first, then adding koji and quickly mixing" fundamentally solves the problems of imbalanced koji-mash ratio and uneven mixing caused by the traditional "timed spreading and continuous koji addition," ensuring homogeneous fermentation.

[0032] Discharge Stage: After mixing, the spreading and cooling motor 7 stops. The tilting discharge motor 2 drives the tilting support frame 5 to tilt downwards, so that the opening of the rotating container shell 1 faces downwards, pouring the mixed mash into the receiving hopper below, completing one whole steaming cycle. The entire process is highly automated, significantly reducing the labor intensity of operators.

[0033] Cleaning and Maintenance: After a batch is completed, the equipment can be activated for self-cleaning. Water is sprayed into the rotating container shell 1 while the shell is rotated and slightly overturned. Wastewater is discharged through the inspection manhole. The rotating container shell can be easily rinsed and steam-sterilized, solving the problems of difficult cleaning and residue buildup associated with traditional equipment.

[0034] Compared to existing drying beds, this device adopts a vertical rotating design, transforming the traditional large-scale flat drying area into a compact three-dimensional device, greatly improving space utilization. At the same time, the mash completes all processes within the container, reducing cross-contamination with the workshop environment and effectively lowering the risk of contamination by miscellaneous bacteria.

[0035] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
