Description

Technical Field

[0001] This utility model relates to the field of brewing technology, and in particular to a storage device for yeast raw materials. Background Technology

[0002] In the brewing industry, the quality of yeast plays a decisive role in the flavor, taste, and fermentation efficiency of alcoholic beverages. Grains such as wheat, sorghum, and barley are the core raw materials for yeast production, and the aeration during their storage directly affects the quality of these raw materials, which in turn affects the quality of the yeast.

[0003] Currently, the existing storage devices for yeast raw materials have poor ventilation. The hot and humid gases generated inside the grain pile due to the respiration of the grains cannot be discharged in time, resulting in local temperature and humidity increases in the grain pile. This makes it very easy for harmful microorganisms such as mold and bacteria to grow, causing the raw materials to spoil.

[0004] Therefore, it is necessary to develop a yeast raw material storage device to address the above-mentioned shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a storage device for yeast starter raw materials that can improve the ventilation effect of the yeast starter raw materials.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model discloses a storage device for yeast starter raw materials, including a silo for storing yeast starter raw materials, the top of the silo being fixed with a silo cover and the inner cavities of the two being connected, and further comprising:

[0008] A vertical pipe, with its two ends sealed and vertically installed inside the silo, and the vertical pipe is provided with multiple exhaust structures for airflow discharge;

[0009] An air intake component is fixedly connected to the outer wall of the silo, and the air intake component communicates with the bottom inner cavity of the vertical pipe;

[0010] An air extraction assembly is disposed at the top of the silo and communicates with the silo.

[0011] Optionally, the vertical pipe includes multiple separate pipe sections, and valves are fixed and connected between adjacent separate pipe sections.

[0012] Optionally, a radar level gauge for measuring the height of the yeast raw materials inside the silo is fixed on the silo cover.

[0013] Optionally, the valve is an electric valve.

[0014] Optionally, multiple vertical pipes are provided and evenly distributed around the circumference, and multiple fixing rods are fixed between the vertical pipes and the inner wall of the silo.

[0015] Optionally, the air intake component has an annular structure and an annular inner cavity. The bottom of the vertical pipe is fixed and connected to a connecting pipe. The end of the connecting pipe away from the vertical pipe is connected to the annular inner cavity. An air intake pipe connected to an externally installed high-pressure gas supply device is fixed on the air intake component, and the air intake pipe is connected to the annular inner cavity.

[0016] Optionally, the air extraction assembly includes a housing with an annular cavity and an air extraction pipe fixedly connected to the housing. The air extraction pipe is used to communicate with an externally installed ventilation device and is also connected to the annular cavity. A plurality of air extraction holes are provided on the flange plate at the top of the silo. One end of each air extraction hole is connected to the annular cavity, and the other end is connected to the inner cavity of the silo cover.

[0017] Optionally, the exhaust structure is a long, narrow slit.

[0018] Optionally, the width of the gap is 0.1 to 1.5 mm.

[0019] Optionally, both ends of the vertical pipe are sealed by detachably connected plates.

[0020] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0021] The height of the yeast raw material in the silo is measured by a radar level gauge, which allows the valve above the yeast raw material to be closed to prevent airflow short-circuiting and ensure that the airflow flows upward through the gaps inside the grain pile.

[0022] High-pressure gas from the outside is diverted to each vertical pipe through the annular inner cavity of the air intake component, and injected into the internal gaps of the grain pile through the exhaust structure, forming an airflow from bottom to top; at the same time, the exhaust device draws gas from the top of the silo through the exhaust hole, forming a negative pressure inside the silo, accelerating the airflow and carrying away the hot and humid gas.

Detailed Implementation

[0027] The core of this utility model is to provide a storage device for yeast starter raw materials, which can improve the ventilation effect of yeast starter raw materials.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "setting", "installing", "connecting", "joining", "fixing", "sleeving", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In a specific embodiment of this utility model, a silo 100 for storing yeast raw materials is included. A silo cover 200 is fixed to the flange plate at the top of the silo 100 by bolts, and the inner cavities of the two are connected. An inlet for yeast raw materials to enter the silo 100 is provided on the silo cover 200. An auger conveyor for discharging yeast raw materials is provided at the bottom of the silo 100.

[0032] Also includes:

[0033] The vertical pipe 300 is sealed at both ends and vertically installed inside the silo 100, and multiple exhaust structures 310 for airflow discharge are provided on the vertical pipe 300.

[0034] The air intake component 400 is fixedly connected to the outer wall of the silo 100, and the air intake component 400 is connected to the bottom inner cavity of the vertical pipe 300.

[0035] An air extraction assembly is located at the top of the silo 100 and is connected to the silo 100.

[0036] During the storage of yeast starter raw materials, an externally installed high-pressure gas supply device supplies gas to the air intake component 400. The gas enters the gaps between the yeast starter raw materials through the exhaust structure 310 on the vertical pipe 300. At the same time, an externally installed exhaust device ventilates the interior of the silo 100 to increase the ventilation effect. In actual use, ventilation is carried out 1 to several times a day, for 1 to 3 hours each time.

[0037] In a specific embodiment of this utility model, the vertical pipe 300 includes multiple split pipe segments, and valves 500 are fixedly connected between adjacent split pipe segments.

[0038] In one specific embodiment of this utility model, a radar level gauge 600 for measuring the height of the yeast raw material inside the silo 100 is fixed on the silo cover 200. The radar level gauge 600 may be equipped with an air sweeping function to prevent dust adhering to the working end from affecting its performance.

[0039] In a specific embodiment of this utility model, valve 500 is an electric valve.

[0040] Both valve 500 and radar level gauge 600 are connected to an external controller. The radar level gauge 600 measures the height of the yeast raw material in the silo 100 and feeds the signal back to the controller. The controller controls the valve 500 above the yeast raw material to close, preventing the airflow in the vertical pipe 300 from being directly discharged into the silo 100 through the exhaust structure 310 above the yeast raw material and then being drawn away by the air extraction component, ensuring that the airflow flows upward through the gaps inside the grain pile.

[0041] In addition, multiple temperature and humidity sensors can be installed inside the silo 100. Both temperature and humidity sensors are connected to an external controller. The temperature and humidity inside the silo 100 are monitored by the temperature and humidity sensors. When the temperature and humidity exceed the storage conditions of the yeast raw materials, the controller controls the external high-pressure gas supply device and ventilation assembly to ventilate the silo 100.

[0042] In a specific embodiment of this utility model, multiple vertical pipes 300 are provided and evenly distributed around the circumference, and multiple fixing rods 101 are fixed between the vertical pipes 300 and the inner wall of the silo 100.

[0043] In a specific embodiment of this utility model, the air intake component 400 has a ring structure and an annular inner cavity. The bottom of the vertical pipe 300 is fixed and connected to a connecting pipe 700. The end of the connecting pipe 700 away from the vertical pipe 300 is connected to the annular inner cavity. An air intake pipe 410 is fixed on the air intake component 400 and is connected to an externally installed high-pressure gas supply device (such as a blower, centrifugal fan, etc.), and the air intake pipe 410 is connected to the annular inner cavity. In addition, the air intake end of the high-pressure gas supply device can also be connected to an air drying device or a filter device.

[0044] In a specific embodiment of this utility model, the air extraction assembly includes a housing 800 having an annular cavity and an air extraction pipe 900 fixedly connected to the housing 800. The air extraction pipe 900 is used to communicate with an externally installed air extraction device (such as an axial flow fan), and the air extraction pipe 900 is connected to the annular cavity. A plurality of air extraction holes 110 are provided on the flange plate at the top of the silo 100. One end of the air extraction hole 110 is connected to the annular cavity, and the other end of the air extraction hole 110 is connected to the inner cavity of the silo cover 200.

[0045] In one specific embodiment of this utility model, the exhaust structure 310 is a long strip-shaped slit or through hole.

[0046] In a specific embodiment of this utility model, the width of the slit is 0.1 to 1.5 mm (preferably to ensure that the stored yeast raw material will not enter the interior of the vertical tube 300 through the slit), and the length is 1 to 50 cm. The size of the through hole is preferably such that the yeast raw material cannot pass through.

[0047] In one specific embodiment of this utility model, both ends of the vertical pipe 300 are sealed by detachably connected plates 1000. During maintenance, the plates 1000 can be removed, and dust and other impurities entering the vertical pipe 300 through the exhaust structure 310 can be discharged from the bottom of the vertical pipe 300.

[0048] In addition, when feeding material into the silo 100, the externally installed exhaust device can be turned on to extract the dust through the exhaust assembly.

[0049] The working principle of the yeast raw material storage device of this utility model is as follows: external high-pressure gas is diverted to each vertical pipe 300 through the annular inner cavity of the air inlet component 400, and injected into the internal gap of the grain pile through the exhaust structure 310 to form an airflow from bottom to top; at the same time, the exhaust device extracts the gas from the top of the silo 100 through the exhaust hole 110 to form a negative pressure inside the silo, accelerate the airflow, and carry away the hot and humid gas.

[0050] The radar level gauge 600 monitors the height of the raw material, which allows the valve 500 above the raw material to be closed, forcing airflow to exit only from the exhaust structure 310 within the raw material pile, ensuring ventilation coverage of the effective grain pile area.

[0051] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably, and the embodiments can be combined with each other. For the apparatus disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to in the method section.

[0052] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
