Description

Technical Field

[0001] The invention relates to the technical field of wine-making equipment, and in particular to a grain moistening device for wine-making. Background Art

[0002] Maotai chooses the Double Ninth Festival to "make sand" every year. "Sha" is an industry name for the raw material sorghum of Maotai. Because Maotai's origin is regionally specific, the local sorghum used as its raw material is small, plump and sauce-red, which is very similar to the color of the river sand in the Chishui River. The older generation of winemakers called this sorghum "Sha", and the raw material for the production of Maotai sauce-flavor liquor is called "making sand". When "making sand", the first step is to "run the sand", that is, first pour boiling water (above 95℃) on the crushed sorghum, and stir while pouring water to allow the raw materials to fully absorb water. This process is also called "running grain"; then steam it in a retort, cool it after it comes out of the retort, and add koji to pile it up for fermentation when the temperature drops to the conditions.

[0003] Due to the differences in regions and processes, the taste of the liquor produced varies greatly. For thousands of years, this traditional brewing process has been completed and passed down manually, especially in the cooling process, which requires cooling on the ground. Because of the particularity of the brewing process, many processes cannot be replaced by mechanized production. Brewers adhere to tradition and only brew "Xiasha" during the Double Ninth Festival every year. At least two brewers are required to cooperate when moistening the grain. Before moistening the grain, the raw grain materials are first piled on the ground to form a pile of materials. One of the brewers pours water on the pile, and the other brewers stir it. In the high temperature environment of the Double Ninth Festival, not only is the labor intensity very high, but it is also easy to get burned, which is a severe test for the operators. Under the premise of not changing the traditional brewing process, it is very necessary to appropriately use mechanical operations to reduce the labor intensity in individual process links. According to the characteristics of the brewing process, the inventor designed a grain moistening device for the moistening process during "Xiasha", which can greatly reduce the labor intensity of this process, and this case is generated.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] This embodiment discloses a grain moistening device for brewing wine, and its structure is as follows: Figures 1 to 8 As shown, the entire grain moistening device adopts a hand-pushed walking trolley structure design, the purpose is to facilitate the moistening of the raw material piles that are pre-stacked on the ground and need to be sanded and moistened. The entire trolley adopts a frame-type frame structure, and the four corners of the bottom of the frame 1 are installed with walking wheels 2, and the handrail 3 is installed on the hand-pushed side of the frame 1. The entire grain moistening device can be divided into a loading mechanism, a vertical conveying mechanism, a material-dropping and grain-moistening mechanism, and a power drive mechanism according to function. Among them, the loading mechanism is used to transfer the raw materials in the raw material pile on the ground to the vertical conveying mechanism one by one, and the vertical conveying mechanism transports the raw materials upward to the material drop port 33. A material drop and grain moistening mechanism is set below the material drop port 33. The material drop and grain moistening mechanism sprays water on the raw materials and stirs them evenly. The raw materials after moistening can also be automatically dropped into piles. The power drive mechanism is divided into several units, which provide driving force to each functional mechanism respectively. The specific implementation structure of the attached figure is introduced in detail below.

[0027] The grain moistening device of this embodiment is mainly derived from the consideration of moistening raw grain when sand is discharged. Usually, raw grain is piled up on the ground as raw materials. In order to facilitate the automatic feeding of the raw material pile, the feeding mechanism is arranged on the outside of the frame 1 (the outside of the side opposite to the handrail 3) in this embodiment. In order to facilitate the feeding operation of the raw material pile, the feeding mechanism includes a frame fence, which is used to frame the raw material pile inside for easy transportation. In order not to affect the walking of the grain moistening device, the frame fence is designed to be a structure that can be turned up and down. When pushing the walking, the frame fence is lifted up and put down when feeding is needed. The framed raw materials are transported by a scraper with adjustable height. The vertical conveying mechanism used in this embodiment is a bucket elevator 9, which is installed on the side of the frame 1 close to the feeding mechanism, and the feeding port of the bucket elevator 9 faces the side of the frame fence. The grain-feeding and grain-moistening mechanism comprises a feeding hopper 17, a spraying mechanism and a stirring mechanism. The feeding mechanism delivers the raw materials in the raw material pile into the feeding port of the bucket elevator 9. The bucket elevator 9 lifts the raw materials to the upper feeding port 33. The raw materials fall into the feeding hopper 17 from the feeding port 33. The spraying mechanism sprays water on the raw materials. The stirring mechanism stirs the raw materials. The moistened raw materials fall into a pile from the bottom of the feeding hopper 17.

[0028] The frame fence in this embodiment includes a semi-enclosed fence 4 and a movable scraper. The scraper is arranged at the open end of the fence 4 to form a rectangular frame. The scraper is driven by a horizontal drive mechanism to move forward and backward, and the scraper is driven by a vertical drive mechanism to adjust the height up and down. The open end of the fence 4 is hingedly mounted on the frame 1, and the closed end of the fence is pulled up and down by the fence lifting mechanism. The fence 4 is surrounded by three baffles to form a U-shaped frame. The fence lifting mechanism includes a fence lifting motor 13 installed on the top of the frame 1, a wire wheel 14 driven by the fence lifting motor 13 and installed at the end of the rotating shaft, a guide wheel 11 installed on the other side of the top of the frame 1, and a lifting wire rope 5. One end of the lifting wire rope 5 is fixed and wound on the wire wheel 14, and the other end is fixed to the top of the closed end of the fence 4 after being guided by the guide wheel 11. Tightening the lifting wire rope 5 can lift the fence 4 upward for easy walking, and lowering the lifting wire rope 5 can lower the fence 4 to a horizontal state.

[0029] The movable scraper can be a whole plate, or it can be designed as a split structure for easy disassembly and assembly as shown in the figure, that is, the scraper can be divided into a pull plate 6 and a scraper plate 7, and the scraper plate 7 is detachably mounted at the bottom of the pull plate 6. The horizontal driving mechanism that drives the scraper to move horizontally includes a transverse guide rail 24, a capstan 25, a steel wire rope 26, a side plate, and a pull plate driving motor 8. Among them, one end of the transverse guide rail 24 is fixedly mounted on the inner wall of the pull plate 6, and the other end remains suspended. Rollers 27 are respectively arranged on the upper and lower sides of the transverse guide rail 24, so that the rollers 27 can roll along the surface of the transverse guide rail 24. The rollers 27 are mounted on the side plates, and a rotating shaft is also mounted on the side plates. The rotating shaft is driven by the pull plate driving motor 8, and a capstan 25 is mounted on the rotating shaft. The steel wire rope 26 is wound around the capstan 25, and the two ends of the steel wire rope 26 are fixed to the two side end plates of the transverse guide rail 24. The steel wire rope 26 is always kept in a straight state from the capstan 25 to the fixed end. When the scraper needs to be moved forward and backward, the pull plate driving motor 8 drives the capstan 25 to rotate.

[0030] The vertical driving mechanism for driving the scraper to adjust the height up and down includes a plate lifting motor 10, a lifting belt 20 and a lifting pulley 22. The plate lifting motor 10 drives the lifting pulley 22 to rotate through a rotating shaft. One end of the lifting belt 20 is wound around the lifting pulley 22, and the other end is fixed to the scraper. Considering the strength design requirements, this embodiment is to install a cross bar 21 on the side panel, and fix the other end of the lifting belt 20 to the top of the cross bar 21. In order to ensure the smooth up and down movement of the pull plate 6, a vertical guide rail 19 is also set on the frame 1, and a roller 23 is installed on the side panel, so that the roller 23 is distributed on the front and rear sides of the vertical guide rail 19 and rolls along the guide rail groove.

[0031] The outside of the bucket elevator 9 is an elevator cover, and a plurality of elevator buckets 32 are distributed on the front and rear sides of the cover. The lower part of the bucket elevator 9 is an elevator feed port 31. The elevator motor 12 that drives the bucket elevator 9 to transport upward is installed on the top of the frame 1, and the transmission force is provided by the cooperation of gears and chains (referred to as sprockets). An auger 30 and an auger motor 18 are provided at the elevator feed port 31. The auger motor 18 drives the auger 30 to rotate and deliver the raw materials sent by the scraper plate 7 to the feed port 31. The raw materials entering the feed port 31 are delivered to the elevator bucket 32, and are transported upward to the drop port 33 by the elevator bucket 32.

[0032] The grain-feeding and grain-moistening mechanism can be flexibly designed according to the functional requirements of its spraying water and stirring, and is not limited to the structure shown in this embodiment. Since the original intention of the grain moistening device of the present invention is to carry out sand-feeding operations to moisten grain, the spraying water requires hot water with a relatively high temperature. Therefore, considering the effect of grain moistening, the spraying and stirring mechanism in this embodiment is designed to be processed in two levels, upper and lower. The primary material-feeding and stirring mechanism is located at the upper part, and the material-feeding and grain-moistening mechanism is located at the lower part. The upper and lower levels of grain moistening and stirring are used to make the grain moistened more fully, and the two-level grain moistening is not limited to the independent use of a certain level of spraying.

[0033] The primary material dropping and stirring mechanism includes a trough 34 located below the bucket elevator drop port 33 and a conveyor belt 47 located at the bottom of the trough 34. A spray pipe 40 is installed above the trough 34. A water outlet is provided at the bottom of the spray pipe 40. The conveyor belt 47 is driven by a conveyor belt motor 46 to drive a sprocket assembly. The sprocket assembly includes a chain cover 45 and an internal chain 48 and a gear. A rake-shaped stirring shaft 43 is installed in the trough 34. The rake-shaped stirring shaft 43 is driven by a rake-shaped stirring shaft motor 42 installed outside the trough. The raw materials dropped from the drop port 33 fall onto the conveyor belt 47. The spray pipe 40 sprays the raw materials. After being stirred by the rake-shaped stirring shaft 43, the raw materials are sent to the drop hopper 17 of the lower material dropping and grain moistening mechanism for secondary spraying and stirring. To ensure continuous feeding of the conveyor belt 47, the material trough 34 in this embodiment is a semi-enclosed structure surrounded by three baffles and a material drop adjustment plate 41 arranged at the unenclosed end. The material drop adjustment plate 41 can play a certain role in blocking and delaying the falling of the raw materials transmitted by the conveyor belt 47, and can make a part of the raw materials appropriately accumulate at the discharge end of the conveyor belt 47 to maintain continuous downward dropping, so that the raw materials fall from the gap between the material drop adjustment plate 41 and the conveyor belt 47.

[0034] The material-feeding and grain-moistening mechanism includes a material-feeding and stirring motor 37, a vertical stirring shaft 39, a bearing 49, a nozzle plate 50, and a stirring impeller 51 from top to bottom. The material-feeding and stirring motor 37 is mounted on a motor mounting seat 38, which is fixed on the frame 1. The top of the vertical stirring shaft 39 is driven to rotate by the material-feeding and stirring motor 37, and a stirring impeller 51 is installed at the bottom of the vertical stirring shaft 39 as a stirring mechanism. The nozzle plate 50 is used as a spraying mechanism. The nozzle plate 50 is sleeved on the outside of the vertical stirring shaft 39. A plurality of water outlets or nozzles are arranged at the bottom of the nozzle plate 50. The nozzle plate 50 and the spraying pipe 40 are both connected to the water inlet pipeline 16. The water inlet interface 15 of the water inlet pipeline 16 is connected to an external water supply source. The water inlet pipeline 16 is installed with a solenoid valve 28 for controlling the water inlet switch and a regulating valve 29 for adjusting the water inlet amount. The bearing 49, the nozzle plate 50, and the stirring impeller 51 are all arranged in the material-feeding hopper 17, and a material-feeding hopper cover plate 44 is arranged above the material-feeding hopper 17.

[0035] Taking into account that the grain moisturizer of the present embodiment can be used for grain moisturizing operations in the sand discharge stage, the raw materials after moistening still need to be piled on the ground to form a stack. In order to allow the raw materials to automatically stack into a stack after falling, the present embodiment also installs a discharging cone 36 at the bottom of the discharge hopper 17 in a detachable manner, and provides a cross spoiler 35 at the bottom discharge port of the discharging cone 36 to allow the raw materials to fall from the cross notch to avoid dispersion.

[0036] The grain moistening device designed by the present invention can be pushed to one of the raw material piles, the fence 4 can be lowered and the various driving mechanisms can be opened. With the cooperation of the scraper plate 7 that continuously decreases in height and moves back and forth, the raw materials in the raw material pile are pushed layer by layer into the elevator feed port 31, and are transported vertically upward by the elevator. In the process of dropping materials, automatic water spraying and stirring and moistening of grains are completed, and finally the materials are dropped to the rear of the original raw material pile and stacked into shape. This device is very suitable for the grain moistening operation of a large number of raw material piles that are pre-stacked on the ground in a large area in a brewery. The entire device is compact and does not take up space. It can automatically complete material feeding, conveying, moistening and dropping materials into piles, and transfer the raw material pile from the front to the rear for displacement. This is very practical and efficient for workshops with relatively tight space on the ground, and can completely replace manual operations, greatly reducing labor intensity.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
