Description

A grain-moistening device for baijiu brewing Technical Field

[0001] This utility model relates to the field of liquor brewing technology, specifically to a grain moistening device for liquor brewing. Background Technology

[0002] In the process of brewing baijiu (Chinese liquor), moistening the grains is a crucial step. Its purpose is to allow the grains to absorb an appropriate amount of water, facilitating subsequent steaming and gelatinization, and creating favorable conditions for saccharification and fermentation. Traditional grain moistening devices used in baijiu brewing have many shortcomings.

[0003] The mixing uniformity of the grains and the soaking liquid is poor. In common equipment, the liquid is often sprayed directly onto the surface of the grains, making it difficult to ensure that the grains can absorb water evenly. This results in some grains not being adequately moistened, affecting the subsequent fermentation effect and thus reducing the quality and yield of the liquor. Summary of the Invention

[0007] A grain storage box is provided on the outer wall of the top of the grain condenser, and the bottom output end of the grain storage box is connected to the input end of the grain conveying channel through a grain transition channel.

[0012] To better realize this utility model, a rotating shaft is further provided at the center of both end faces of the rotating cylinder. The rotating shaft is rotatably mounted in the rotating mounting cavity through bearings. Furthermore, an installation plate is provided on the outside of the opening and closing cylinder.

[0017] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0018] 1. In this utility model, the grain moistening device, through its uniquely designed liquid input channel, liquid buffer chamber, and multiple moistening channels with spray nozzles, enables the moistening liquid to be evenly sprayed onto the grain passing through the moistening channels. During the process of the grain entering the moistening cavity, preliminary uniform mixing of the grain and liquid is achieved. Combined with the suspended stirring of the stirring blades, this ensures that the falling grain and liquid are fully mixed in the air, greatly improving the uniformity of moistening.

Simultaneously, a valve can be installed on the grain transition channel to facilitate control of the grain conveying volume, improving operational flexibility and controllability.

[0020] 3. This utility model device includes a filter cylinder. The filter plate inside the cylinder effectively removes impurities from the grain-moistening liquid, ensuring its purity and preventing impurities from adversely affecting grain quality and subsequent brewing processes. Furthermore, the switching through-hole on the rotating cylinder, in conjunction with the opening and closing of the cylinder body, allows for precise control of the flow rate and on / off state of the grain-moistening liquid. This can be flexibly adjusted according to actual grain-moistening needs, reducing water waste and ensuring the stability of the moistening effect.

[0021] 4. In this utility model, the structural design of each component is reasonable.

When the rotated switching through hole 310 is in a horizontal state, the opening and closing channel inlet 303 and the opening and closing channel outlet 304 are disconnected.

[0048] As shown in Figures 1 to 16, in this embodiment, a rotating shaft 306 is provided at the center of both end faces of the rotating cylinder 305.

[0049] As shown in Figures 1 to 16, in this embodiment, the grain moistening device further includes a stirring rod 401. One end of the stirring rod 401 passes through the stirring mounting hole 103 from bottom to top and extends into the grain moistening cavity (the stirring rod 401 and the stirring mounting hole 103 are provided with an existing mature rotation seal), and a stirring blade 402 is provided at its end. The other end of the stirring rod 401 is connected to the output end of the second motor 403.

[0050] As shown in Figures 1 to 16, in this embodiment, the grain moistening channel is arranged at an angle, with the input end of the grain moistening channel being high and the output end being low.

The acute angle between the grain transition channel 112 and the horizontal plane is 30° to 60°.

[0054] Working principle:

[0055] Starting the first motor 307 causes the rotating cylinder 305 to rotate synchronously, thereby making the switching through hole 310 either vertical or horizontal. When the switched through hole 310 is vertical after rotation, the opening and closing channel inlet 303 and the opening and closing channel outlet 304 are connected. When the switched through hole 310 is horizontal after rotation, the opening and closing channel inlet 303 and the opening and closing channel outlet 304 are disconnected.

[0056] Start the second motor 403 to drive the stirring blade 402 to rotate synchronously.

[0057] During the grain moistening process, the operator first pours the moistening liquid into the water storage tank 302, and then pours the grain into the grain storage tank 111. The grain sequentially enters the grain transition channel 112 (during which the valve on the grain transition channel 112 is opened), the grain conveying channel 114, and the moistening channel composed of the upper semi-circular moistening pipe flap 107 and the lower semi-circular moistening pipe flap 113, until it enters the moistening cavity. During this process, the second motor 403 starts, causing the stirring blade 402 to rotate, and the first motor 307 starts, connecting the opening / closing channel inlet 303 and the opening / closing channel outlet 304. The moistening liquid (e.g., water) sequentially enters the opening / closing channel inlet 303, the switching through hole 310, the opening / closing channel outlet 304, the filter plate 202 (which has filter holes), the liquid input channel 105, the liquid buffer chamber 106, the semi-circular liquid conveying channel 108, and the water spray hole 109. The grain is moistened in the process. During the process of entering the grain moistening cavity through the grain moistening channel, the liquid used for moistening the grain is sprayed onto the grain through the water spray hole 109. The grain mixed with liquid is then stirred in the air by the stirring blade 402, so that the falling grain and liquid are fully mixed in the air. After stopping the pouring of grain into the grain storage box 111 for 1-2 minutes, the first motor 307 is restarted, and the switching through hole 310 is rotated to a horizontal state, so that the connection between the opening and closing channel inlet 303 and the opening and closing channel outlet 304 is disconnected, and the second motor 403 is stopped.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
