Description

Technical Field

[0001] This utility model relates to the field of still-making equipment, and more particularly to a still-making equipment for brewing wine. Background Technology

[0002] In the brewing industry, the stilling device is a core piece of equipment for key processes such as distillation and cooking of solid-state fermented mash, and its performance directly affects the quality of the wine and production efficiency. With the increasing demand for large-scale and automated development in the brewing industry, technological innovation of the stilling device has become a focus of continuous attention in the industry. There is an urgent need to meet the requirements of modern brewing processes for high efficiency, energy saving, and safety through structural optimization and functional upgrades.

[0003] Traditional still-distillation equipment mainly consists of the still body, the still grate, and manually operated components. The still body serves as the main container for holding the fermented mash, while the still grate supports the mash and ensures even steam penetration. During operation, workers manually spread the mash layer by layer into the still to complete the loading process. When removing the mash, they also manually scoop and transfer the fermented mash from the still body. This manual operation mode relies on the worker's experience to control the looseness of the mash and the distribution of steam, thus realizing the distillation process of solid-state fermented mash.

[0004] However, this traditional operating method has significant drawbacks. In the steaming and discharging stages, the process relies entirely on manual operation, resulting in extremely high labor intensity. Workers are required to continuously perform repetitive, high-intensity actions such as carrying, spreading, and shoveling, easily leading to fatigue. Simultaneously, manual operation is inefficient, extending the entire production cycle and failing to meet the demands of modern brewing enterprises for large-scale production. This has become a key bottleneck restricting the automation upgrade and capacity improvement of the brewing industry. Therefore, a steaming device for brewing is proposed to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a still for brewing, which aims to improve the problems of high labor intensity and low efficiency in the traditional brewing process of loading the still and unloading the mash.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A brewing still device includes a double-layer still body, a still lid on top of the double-layer still body, a steam outlet on top of the still lid, a rotating shaft fixedly connected inside the double-layer still body, a plurality of openable and closable door panels rotatably connected to the outer wall of the rotating shaft, each of the openable and closable door panels having a plurality of holes, and rollers fixedly connected to the bottom of each of the openable and closable door panels, and a ground pot at the bottom of the double-layer still body, a steam pipe and a drain pipe fixedly connected inside the ground pot, one end of the steam pipe extending to the inner wall of the ground pot and fixedly connected to a gas exhaust pipe.

[0008] As a further description of the above technical solution:

[0009] One end of the drain pipe extends to the inner wall of the earthen pot, and the other end of the steam pipe and drain pipe extends to the outside of the earthen pot.

[0010] As a further description of the above technical solution:

[0011] The top of the earthen pot is provided with a sealed water groove, and the multiple rollers are in contact with the inner wall of the earthen pot.

[0012] As a further description of the above technical solution:

[0013] Multiple unloading switches are fixedly connected to the bottom of the outer wall of the double-layer steamer, and multiple lifting rings are fixedly connected to the top of the outer wall of the double-layer steamer.

[0014] As a further description of the above technical solution:

[0015] Both sides of the steamer cover are fixedly connected with lifting rings, and the bottom of the steamer cover is fixedly connected with a sealing strip.

[0016] As a further description of the above technical solution:

[0017] A venting rod is fixedly connected to the top of the steamer cover, and one end of the venting rod is connected to the steam outlet.

[0018] As a further description of the above technical solution:

[0019] The double-layered steamer body is housed inside the earthen pot and the steamer lid.

[0020] This utility model has the following beneficial effects:

[0021] This invention achieves automatic loading and rapid unloading of the fermented mash through a clever linkage design between rollers and an openable / closable door panel. This effectively solves the technical problems of high labor intensity and low efficiency in the loading and unloading stages of traditional brewing processes. Simultaneously, the introduction of the unloading switch enables reliable locking and control of the door panel's opening and closing status.

[0029] 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.

[0030] Reference Figures 1-5This utility model provides an embodiment of a brewing still device, comprising a double-layered still body 1, with a still lid 2 on top of the double-layered still body 1. The still lid 2 is used to seal the top of the double-layered still body 1 to collect steam, thereby preventing the leakage of alcohol vapor. A steam outlet 15 is provided on the top of the still lid 2 to exhaust the vaporized alcohol and flavor substances inside the double-layered still body 1, providing a channel for subsequent condensation and collection. A rotating shaft 12 is fixedly connected inside the double-layered still body 1. The rotating shaft 12 serves as the rotation center for the flipping of the openable and closable door panels 13, realizing the structural support for the opening and closing action of the door panels. Multiple openable and closable door panels 13 are rotatably connected to the outer wall of the rotating shaft 12. They are flipped in conjunction with the rollers 14 and the inner wall of the pot 5, achieving automatic reception of the mash. To facilitate automatic unloading, each openable door panel 13 has multiple holes. These holes allow the steam generated inside the earthen pot 5 to evenly penetrate and heat the mash above, ensuring the distillation process proceeds fully. Each openable door panel 13 has a fixedly connected roller 14 at its bottom. This roller 14 slides along the inner wall of the earthen pot 5, converting the vertical lifting motion of the double-layer still 1 into the rotational opening and closing motion of the openable door panel 13, achieving mechanical linkage. The earthen pot 5 is located at the bottom of the double-layer still 1, serving as a support for the still 1 and a container for steam generation and waste collection, achieving an integrated base and container. A steam pipe 6 and a drain pipe 9 are fixedly connected inside the earthen pot 5. The steam pipe 6 draws heat from an external heat source to the earthen pot. The inner pot 5 carries high-temperature steam, providing core heat for the entire distillation process. The drain pipe 9 is used to discharge waste and wastewater from inside the pot 5 after distillation, facilitating quick cleaning and maintenance. One end of the steam pipe 6 extends to the inner wall of the pot 5 and is fixedly connected to a gas exhaust pipe 7. This gas exhaust pipe 7 distributes steam evenly at the bottom of the pot 5, ensuring uniform heating of the mash. One end of the drain pipe 9 extends to the inner wall of the pot 5, while the other ends of the steam pipe 6 and drain pipe 9 extend to the outside of the pot 5. A sealing water tank 8 is provided on the top of the pot 5. This sealing water tank 8 is used to inject clean water after the double-layer still body 1 is combined with the pot 5, forming a reliable water seal to prevent steam leakage from the joint. Multiple rollers 14 are mounted on the inner wall of the pot 5. The double-layered still body 1 has multiple unloading switches 4 fixedly connected to the bottom of its outer side wall. These switches are used to manually lock and unlock the openable door 13 when closed, ensuring absolute safety during loading and distillation and controllability during unloading. Multiple lifting rings 10 are fixedly connected to the top of the outer side wall of the double-layered still body 1, specifically for hooking and raising / lowering the entire double-layered still body 1, facilitating assembly and disassembly. Lifting rings 26 are fixedly connected to both sides of the still lid 2, specifically for lifting the lid 2 individually, facilitating opening and closing operations before and after loading. A sealing strip 11 is fixedly connected to the bottom of the still lid 2, providing a reliable elastic seal when the lid 2 and the double-layered still body 1 are closed, ensuring the airtightness of the distillation space.A steam venting rod 3 is fixedly connected to the top of the steam pot lid 2. This steam venting rod 3 connects the steam outlet 15 to the external condensation system, serving as a channel for guiding alcohol vapor. One end of the steam venting rod 3 is connected to the steam outlet 15. The double-layered steam pot body 1 is housed inside the earthen pot 5 and the steam pot lid 2.

[0031] Working Principle: During operation, the operator uses a lifting device to hook the lifting ring 10 on the outer wall of the double-layer still body 1 and lowers it vertically into the earthen pot 5. During descent, the rollers 14 at the bottom of the double-layer still body 1 contact and slide upward along the inner wall of the earthen pot 5. This thrust drives the two openable door panels 13 on both sides to flip upward to the closed position via the rotating shaft 12. Once the door panels are fully closed, the operator must manually operate the unloading switch 4 to lock them, ensuring that the openable door panels 13 remain stable during subsequent loading and distillation processes and will not accidentally open due to the weight of the mash. After the openable door panels 13 are locked, the fermented mash can be safely loaded into the double-layer still body 1. Subsequently, the still lid 2 with sealing strip 11 is closed, forming a heat-insulated and airtight distillation space composed of a double-layer shell. High-temperature steam is then injected into the steam pipe 6 and discharged through multiple exhaust pipes 7. It then penetrates the mash evenly from bottom to top through the holes in the closed door panel, efficiently vaporizing the alcohol and flavor compounds. This mixed steam gathers at the steam outlet 15 at the top and is guided to the external condensation system, where it condenses into alcohol. After distillation, the operator must operate the unloading switch 4 again, moving it to the unlocked position to release the lock on the openable door panel 13. Although the door panel 13 is now unlocked, it remains closed because the rollers 14 are still supported by the inner wall of the earthen pot 5. Next, the entire double-layer steamer body 1 is lifted vertically upwards by a crane. The moment the roller 14 is removed from the support of the inner wall of the pot 5, the openable door 13, which has lost its support, will immediately rotate downwards and open automatically under the gravity of the fermented grains, achieving instant and thorough automatic unloading. Finally, the waste in the pot 5 can be collected and cleaned through the drain pipe 9, ensuring absolute safety of operation and ultimate efficiency of the process.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
