Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquor production technology, specifically to a grain steaming machine for easy feeding in liquor production. Background Technology
[0002] In the production of baijiu (Chinese liquor), grain steaming is a crucial step, directly impacting the quality and production efficiency of the liquor. Traditional grain steaming machines suffer from numerous problems in practical applications.
[0003] On the one hand, uneven steam filling is a common problem. Traditional grain steamers often only allow steam to enter the steaming chamber from a single direction or a limited number of directions, resulting in uneven heating of the grains. Some grains are over-steamed while others are under-steamed. This not only affects the taste and quality stability of the liquor, but also reduces the utilization rate of the raw materials.
[0004] On the other hand, low feeding efficiency severely restricts production progress. Traditional grain steamers have a simple feeding structure design, usually relying on gravity or simple mechanical propulsion to discharge grain, which easily leads to grain blockage and uneven feeding. Moreover, when processing large quantities of grain, this feeding method cannot meet the demands of fast and efficient production, increasing production cycles and costs. Utility Model Content
[0005] To address the aforementioned technical problems, this application solves the issues of uneven steam filling and low material feeding efficiency in the prior art.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a grain steaming machine for easy feeding in liquor production, including a grain steaming pot, the grain steaming pot having a grain steaming cavity, and air inlet and air outlet respectively provided on the symmetrical sides of the bottom of the grain steaming pot, which are connected to the grain steaming cavity; an air inlet pipe is provided on the air inlet, and a first valve is provided on the air inlet pipe.
[0007] The top of the grain steamer is provided with a feed hole and a circulation hole. The air outlet is connected to the circulation hole through an air outlet pipe. An air discharge pipe is connected to the air outlet pipe, and a second valve is provided on the air discharge pipe.
[0008] The interior of the grain steaming cavity is divided into upper and lower cavities by the filter plate. The filter plate has several connecting holes. The lower section of the upper cavity is equipped with a feeding component to remove the processed grain from the grain steaming cavity. The air inlet and air outlet of the grain steaming cavity are both located in the lower cavity.
[0009] To better realize this utility model, a grain feeding channel is further provided on the feed hole, a grain feeding funnel is provided at the top of the grain feeding channel, and a third valve is provided between the grain feeding channel and the grain feeding funnel.
[0010] To better realize this utility model, the top of the grain steaming pot is further provided with a stirring hole, which is located between the feed hole and the circulation hole, and a stirring component is provided at the stirring hole.
[0011] To better realize this utility model, the stirring assembly further includes a motor support vertical plate, which is fixedly installed on the top of the grain steaming pot. A second drive motor is provided on the side wall of the motor support vertical plate. A rotating shaft is provided at the output end of the second drive motor. The rotating shaft extends vertically into the grain steaming cavity through the stirring hole, and a stirring blade is provided at the bottom of the rotating shaft.
[0012] To better realize this utility model, the feeding assembly further includes multiple elongated cylinders, which are arranged in parallel in the top view direction. The left outer wall of the leftmost elongated cylinder and the right outer wall of the rightmost elongated cylinder intersect with the inner wall of the steaming cavity. The multiple elongated cylinders are arranged in a wavy pattern in the front view direction. The portion of the elongated cylinder inside the steaming cavity has an upward-facing notch. A long rotating shaft is rotatably installed inside the elongated cylinder. A discharge spiral blade is spirally wound on the long rotating shaft. A guide plate is provided between any two elongated cylinders. The guide plate has multiple guide plate filter holes, so that the inner wall of the steaming cavity, the multiple elongated cylinders, and all the guide plates together form a wavy partition structure. The partition structure divides the upper cavity into an upper grain storage cavity and a lower buffer cavity.
[0013] One end of the long rotating shaft is rotatably connected to one end face of the long cylinder via a bearing, and a discharge port is provided on the lower side of this end of the long cylinder; the other end of the long rotating shaft is rotatably connected to the other end face of the long cylinder via another bearing, and the other end of the long rotating shaft extends out of the other end face of the long cylinder and is provided with a driven pulley.
[0014] The bottom of the grain steamer is provided with a support platform located below the driven pulley. Multiple first drive motors are provided on the upper surface of the support platform. The output end of the first drive motor is provided with a drive pulley. The driven pulley and the drive pulley are connected by a belt.
[0015] To better realize this utility model, the bottom of the grain steamer is further provided with a pair of symmetrically arranged support vertical plates. The front side of the two support vertical plates is provided with a storage groove, which can be located below the discharge port. Each support vertical plate is provided with a hydraulic telescopic rod corresponding to the storage groove.
[0016] The technical solution provided by this utility model has the following advantages compared with the prior art:
[0017] 1. This utility model improves the uniformity of steam filling.
[0018] The grain steamer of this invention employs a unique steam introduction method. Part of the steam enters the bottom of the grain storage chamber from below through the connecting holes of the filter plate and the filter holes of the guide plate, while another part of the steam enters the top of the grain storage chamber through the exhaust pipe. This multi-directional steam introduction design allows the steam to contact the grain more comprehensively and evenly, avoiding the problem of uneven steaming results caused by uneven steam introduction in traditional grain steamers, thereby improving the quality stability of the liquor and the utilization rate of raw materials.
[0019] 2. This utility model significantly improves material feeding efficiency.
[0020] In the feeding assembly, multiple long cylinders are arranged parallel to each other in the top view and spaced in a wavy pattern in the front view, forming a wavy partition structure. This design not only increases the bottom contact area with steam, allowing the grain to be heated more thoroughly, but also increases the number of long cylinders. More long cylinders can transport grain simultaneously, greatly improving feeding efficiency and effectively solving the problems of uneven feeding and easy clogging in traditional grain steamers. This meets the needs of large-scale liquor production, shortens the production cycle, and reduces production costs.
[0021] 3. This utility model is easy to clean and maintain.
[0022] The bottom side wall of the grain steamer has a drain port that communicates with the bottom of the steaming cavity, and a fourth valve is installed to facilitate the drainage of liquid from the steaming cavity during cleaning. Meanwhile, the side wall of the buffer chamber has an openable and closable window for easy cleaning of the buffer chamber, preventing the accumulation of impurities. These designs make cleaning and maintenance of the grain steamer more convenient, effectively ensuring the hygiene of the equipment and extending its service life.
[0023] 4. This utility model enhances ease of operation.
[0024] By rationally configuring the various valves and drive motors, operators can easily control the grain feeding, steam injection and discharge, and grain unloading processes. For example, during feeding, the third valve is opened and the stirring assembly is started; after feeding is complete, the third valve is closed. During steam injection and discharge, the first and second valves are controlled respectively. During unloading, the first drive motor is driven, controlling the opening and closing of the fifth valve. This clear and unambiguous operating procedure reduces the labor intensity of operators and improves the accuracy and efficiency of production operations. Attached Figure Description

[0042] Example 1:
[0043] like Figures 1 to 9 As shown, a grain steaming machine for easy feeding in liquor production includes a grain steaming pot 101. The grain steaming pot 101 has a grain steaming cavity. The bottom of the grain steaming pot 101 is symmetrically provided with an air inlet and an air outlet that communicate with the grain steaming cavity. An air inlet pipe 102 is provided on the air inlet, and a first valve 103 is provided on the air inlet pipe 102.
[0044] The top of the grain steamer 101 is provided with a feed hole and a circulation hole. The air outlet is connected to the circulation hole through an air outlet pipe 104. An air discharge pipe 105 is connected to the air outlet pipe 104, and a second valve 106 is provided on the air discharge pipe 105.
[0045] The interior of the grain steaming cavity is divided into upper and lower cavities by the filter plate 110. The filter plate 110 has several connecting holes (the diameter of the connecting holes is designed so that the grain cannot pass through the connecting holes). The lower part of the upper cavity is provided with a feeding component to remove the grain that has been processed in the grain steaming cavity. The air inlet and air outlet of the grain steaming cavity are both located in the lower cavity.
[0046] like Figures 1 to 9 As shown in this embodiment, a grain inlet channel 107 is connected to the feed hole, a grain inlet funnel 109 is connected to the top of the grain inlet channel 107, and a third valve 108 is provided between the grain inlet channel 107 and the grain inlet funnel 109.
[0047] like Figures 1 to 9As shown in this embodiment, the top of the grain steaming pot 101 is also provided with a stirring hole, which is located between the feed hole and the circulation hole, and a stirring component is provided at the stirring hole.
[0048] like Figures 1 to 9 As shown, in this embodiment, the stirring assembly includes a motor support vertical plate 126, which is fixedly installed on the top of the grain steaming pot 101. A second drive motor 127 is provided on the side wall of the motor support vertical plate 126. A rotating shaft 128 is provided at the output end of the second drive motor 127. The rotating shaft 128 extends vertically into the grain steaming cavity through the stirring hole, and a stirring blade 129 is provided at the bottom of the rotating shaft 128.
[0049] like Figures 1 to 9 As shown, in this embodiment, the feeding assembly includes multiple elongated cylinders 111. These cylinders are arranged in parallel in the top view, with the left outer wall of the leftmost cylinder 111 and the right outer wall of the rightmost cylinder 111 intersecting the inner wall of the steaming cavity. The cylinders are arranged in a wavy pattern in the front view. Each elongated cylinder 111 has an upward-opening notch 112 located inside the steaming cavity. A long rotating shaft 113 is rotatably mounted inside each cylinder 111, and a discharge spiral blade 114 is spirally wound around the long rotating shaft 113. (The last sentence appears to be incomplete and possibly refers to a different embodiment.) A guide plate 115 is provided between the two elongated cylinders 111. The guide plate 115 has multiple guide plate filter holes 116, so that the inner wall of the grain steaming cavity, the multiple elongated cylinders 111, and all the guide plates 115 together form a wave-shaped partition structure. This partition structure divides the upper cavity into an upper grain storage cavity and a lower buffer cavity (the grain storage cavity and the buffer cavity are connected only through the guide plate filter holes 116, and the diameter of the guide plate filter holes 116 is designed to prevent grain from passing through them). An openable and closable window is provided on the side wall of the buffer cavity to facilitate clearing of the interior and prevent the accumulation of impurities.
[0050] One end of the long rotating shaft 113 is rotatably connected to one end face of the long cylinder 111 via a bearing, and a discharge port 125 is provided on the lower side of this end of the long cylinder 111; the other end of the long rotating shaft 113 is rotatably connected to the other end face of the long cylinder 111 via another bearing, and the other end of the long rotating shaft 113 extends out of the other end face of the long cylinder 111 and is provided with a driven pulley 117;
[0051] The bottom of the grain steamer 101 is provided with a support platform 121 located below the driven pulley 117. Multiple first drive motors 120 are provided on the upper surface of the support platform 121. The output end of the first drive motor 120 is provided with a drive pulley 118. The driven pulley 117 and the drive pulley 118 are connected by a belt 119.
[0052] like Figures 1 to 9 As shown in this embodiment, the bottom of the grain steamer 101 is also provided with a pair of symmetrically arranged support vertical plates 122. The front side of the two support vertical plates 122 is provided with a storage groove 124. The storage groove 124 can be located below the discharge port 125. Each support vertical plate 122 is provided with a hydraulic telescopic rod 123 corresponding to the storage groove 124.
[0053] To facilitate cleaning or drainage of liquid from the steaming cavity within the steaming pot 101, a drain port communicating with the inner bottom of the steaming cavity can be provided on the side wall of the bottom of the steaming pot 101. A fourth valve is installed on the drain port. A fifth valve is installed at the discharge port 125. All valves are for opening and closing purposes and utilize existing mature technologies, as are their installation and connection methods.
[0054] Untreated grain enters the storage chamber through the grain inlet funnel 109. During this process, the third valve 108 is opened, and simultaneously, the second drive motor 127 is started to drive the stirring blade 129 to rotate. After all the untreated grain has been added, the third valve 108 is closed.
[0055] The first valve 103 connects to external steam (either pressurized or unpressurized steam, depending on actual needs). A portion of the steam passes through the connecting holes of the filter plate 110 and the guide plate filter holes 116 of the guide plate 115, entering the bottom of the grain storage chamber from below. The remaining steam passes through the exhaust pipe 104 and enters the top of the grain storage chamber, thus ensuring more even steam distribution (during this process, the second valve 106 is closed). Once sufficient steam has been supplied, the first valve 103 is closed.
[0056] When the internal steam needs to be released, simply open the second valve 106.
[0057] The design of the wave-shaped partition structure increases the contact area between the bottom and the steam. At the same time, it increases the number of long cylinders 111, allowing more long cylinders 111 to transport the grain out of the steaming cavity (specifically, the grain located in the storage cavity), thus improving the feeding efficiency.
[0058] The first drive motor 120 drives the active pulley 118 to rotate, which in turn drives the driven pulley 117 to rotate via the belt 119. The long rotating shaft 113 rotates synchronously, and the discharge spiral blade 114 drives the grain that enters through the notch 112 to move towards the outside of the grain storage chamber until it is discharged through the discharge port 125 (during this process, the fifth valve set at the discharge port 125 is open, and is closed at other times) and falls into the collection trough 124. After the collection trough 124 has collected a certain amount of processed grain, the hydraulic telescopic rod 123 is activated, so that the collection trough 124 moves horizontally below the discharge port 125 (multiple rollers can be set at the bottom of the collection trough 124) to facilitate subsequent processing by the operator.
[0059] 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.
