[0002] Grain moistening is one of the key processes in the brewing of Maotai-flavor liquor and an important part of the brewing process. The quality of grain gelatinization mainly depends on the water absorption of the grain. If the grain absorbs enough water, it is easy to heat and cook, that is, the gelatinization is good. If the grain absorbs insufficient water, the gelatinization effect is poor, and the grain has a raw core, similar to "raw rice". Therefore, grains containing appropriate moisture are conducive to gelatinization, easy to steam, so as to achieve the purpose of starch expansion and splitting, high wine yield, and improved wine quality.

[0034] The feeding unit 4 includes a feeding mechanism for conveying the grains to be moistened with water to the grain moistening unit 3 and a feeding mechanism for conveying the grains moistened with water in the grain moistening unit 3 to the carrying unit 1;

[0035] The grain moistening unit 3 includes a grain moistening tank 301 driven to rotate by a driving device and a water spray pipe 302 arranged in the grain moistening tank 301. One end of the water spray pipe 302 passes through the grain moistening tank 301 and is connected to the water supply unit 2. A plurality of water spray structures 307 are arranged on the water spray pipe 302. A rotating fixed frame 303 is also fixed inside the grain moistening tank 301 to provide support for the water spray pipe 302. The water spray pipe 302 rotates in coordination with the rotating fixed frame 303.

[0036] The grain moistening system provided by the embodiment of the utility model automatically supplies water through the water supply unit 2, automatically loads and unloads materials through the feeding unit 4, automatically moistens the grains through the grain moistening unit 3, and the carrying unit 1 stacks grains. The entire grain moistening process has a high degree of automation, which reduces the labor intensity of the staff, improves production efficiency, and provides guarantees for the large-scale production and sustainable development of the wine manufacturing industry. In addition, by setting a rotating fixed frame 303 in the grain moistening tank 301 to provide support for the water spray pipe 302, and making the rotating fixed frame 303 and the water spray pipe 302 rotate in coordination, the water spray pipe 302 can be kept fixed during the process of rotating the grain moistening tank 301 to moisten the grain, so that the spraying direction of the water spray structure 307 on the water spray pipe 302 does not change with the rotation of the tank body, the spraying uniformity is better, and the grain is more evenly soaked, and the rotating fixed frame 303 can also provide support for the water spray pipe 302 while stirring the grain in the grain moistening tank 301 as the grain moistening tank 301 rotates, thereby improving the grain moistening effect, and having multiple functions.

[0037] The grain moistening system provided by the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.

[0038] Figure 1 Schematic diagram of a grain moistening system according to at least one embodiment of the present invention. Figure 1The grain moistening system includes: a carrying unit 1, a water supply unit 2, a grain moistening unit 3 and a feeding unit 4.

[0039] In this embodiment, the grain moistening unit 3 is used to moisten the grain, and specifically includes a grain moistening tank 301. The grain moistening tank 301 is a rotating body structure, such as a cylindrical tank body, an ellipsoidal tank body, etc. Figure 1 The embodiment in which the grain moistening tank 301 is an ellipsoidal tank body is exemplarily shown. With such arrangement, the grain moistening tank 301 has better rotation balance, which is beneficial to the moisture of the grain.

[0040] See also Figure 1 The grain conditioning tank 301 is installed on the equipment support 5 in a horizontal position and is driven to rotate by the driving device. Specifically, the driving device includes a driving motor 304 and a transmission mechanism 305. The driving motor 304 is fixedly installed on the equipment support 5. The transmission mechanism 305 is connected between the driving motor 304 and the grain conditioning tank 301 to transmit the torque of the driving motor 304 to the grain conditioning tank 301, thereby driving the grain conditioning tank 301 to rotate. The transmission mechanism 305 can be an existing gear transmission mechanism, for example, see Figure 1 The transmission mechanism 305 includes two pairs of driving gears and two driven gears. The two pairs of driving gears are rotatably installed on the equipment bracket 5 through a connecting shaft. The connecting shaft is transmission-connected to the driving motor 304. The two driven gears are fixedly mounted on the grain moistening tank 301. The grain moistening tank 301 is placed on the two pairs of driving gears, and the two driven gears are respectively meshed with the two pairs of driving gears. In this way, when the driving gear rotates, the grain moistening tank 301 can be driven to rotate through the driven gear.

[0041] See also Figure 1 and Figure 2 The grain conditioning tank 301 is also provided with a water spray pipe 302 and a rotating fixed frame 303. The rotating fixed frame 303 is a rod, and the rotating fixed frame 303 is fixedly installed in the grain conditioning tank 301 along the radial direction of the grain conditioning tank 301. The water spray pipe 302 is extended along the rotation axis of the grain conditioning tank 301, and one end of the water spray pipe 302 passes through the grain conditioning tank 301 and is connected to the water supply unit 2. The middle part of the water spray pipe 302 is rotatably matched with the rotating fixed frame 303, and a plurality of water spray structures 307 are provided on the water spray pipe 302. With such arrangement, the rotating fixed frame 303 provides support for the water spray pipe 302 in the grain moistening tank 301, thereby ensuring the stability of the water spray pipe 302, and because the water spray pipe 302 and the rotating fixed frame 303 rotate in coordination, when the rotating fixed frame 303 rotates with the grain moistening tank 301 to stir the grain, the water spray pipe 302 can rotate relative to the rotating fixed frame 303 and remain fixed, so that the spraying direction of the water spray structure 307 does not change with the rotation of the tank body, the spraying uniformity is better, and the grain is soaked more evenly.

[0042] See also Figure 2The water spray pipe 302 is rotatably matched with the rotating fixed frame 303 through the rotating member 306. Specifically, in the present embodiment, the rotating member 306 can select an existing bearing, the bearing is arranged in the middle of the rotating fixed frame 303, and is located on the rotation axis of the grain moistening tank 301, and the outer ring of the bearing is fixedly connected to the rotating fixed frame 303, and the water spray pipe 302 is fixedly connected to the inner ring of the bearing. In this way, the rotational coordination of the water spray pipe 302 and the rotating fixed frame 303 can be realized through the bearing.

[0043] Furthermore, in this embodiment, the water spray pipe 302 is prism-shaped, and the side of the water spray pipe 302 facing upward is an edge, for example, see Figure 2 , which exemplarily shows an implementation mode in which the water spray pipe 302 is a triangular prism. Such a configuration can reduce the resistance of grain when it falls due to gravity and prevent grain from accumulating on the water spray pipe 302.

[0044] See also Figure 2 In this embodiment, each water spray structure 307 is spaced apart and distributed on the lower side of the water spray pipe 302 along the length direction of the water spray pipe 302, and the water spray direction is downward. This arrangement can make each water spray structure 307 evenly distributed, thereby improving the uniformity of spraying. The water spray structure 307 can be specifically selected from existing spray heads, nozzles, etc.

[0045] In this embodiment, the water supply unit 2 is used to supply hot water to the grain moistening unit 3 so that the hot water contacts the grain, thereby replenishing moisture for the grain. Figure 1 The water supply unit 2 specifically includes a water adder 201, a power device 203, a connecting pipe 202 and a control valve group.

[0046] The water adder 201 is used to supply hot water. Figure 1 The water adder 201 can specifically be an existing hot water bucket with a water heating function, and the temperature of the hot water is about 97 degrees Celsius.

[0047] The connecting pipe 202 connects the water adder 201 and the grain moistening unit 3. Figure 1 One end of the connecting pipe 202 is connected to the water outlet of the water adder 201, and the other end is fixedly connected to the water spray pipe 302, so as to transport the hot water of the water adder 201 to the grain moistening unit 3, so as to realize the hot water supply of the grain moistening unit 3. The connecting pipe 202 can specifically be made of existing stainless steel or PPR water pipes.

[0048] See also Figure 1 The power device 203 is arranged on the connecting pipe 202 to provide power for the hot water and pump the hot water. Specifically, an existing ordinary water pump or a metering pump that can measure the flow rate can be selected. The metering pump can control the flow rate and flow rate of the hot water to achieve accurate measurement of grain and water, achieve the purpose of accurate proportioning, and realize accurate grain moistening.

[0049] See also Figure 1 The control valve group includes a valve 204 disposed on the connecting pipe 202 for controlling the connection and disconnection of the connecting pipe 202 .

[0050] In this embodiment, the feeding unit 4 is used to realize the loading and unloading of the lubrication unit, and specifically includes a loading mechanism and an unloading mechanism.

[0051] The feeding mechanism is used to transport the grains to be moistened with water to the grain moistening unit 3. In this embodiment, the grains to be moistened with water can be raw grains, that is, grains that have not been moistened with water, or grains that have been moistened with water once, twice or more times. Figure 1 The feeding mechanism specifically includes a grain pumping machine 401 and a feeding hopper 402, wherein the grain pumping machine 401 is used to extract the grain to be moistened with water, and an existing grain pumping machine can be selected. The feeding hopper 402 is arranged on the equipment bracket 5 and connected between the discharge port of the grain pumping machine 401 and the feed port of the grain moistening tank 301, so as to realize the transitional transportation of grain.

[0052] The unloading mechanism is used to transport the grains moistened by the grain moistening unit 3 to the carrying unit 1. Figure 1 The unloading mechanism includes a unloading hopper 403, which is arranged on the equipment bracket 5 and connected to the discharge port of the grain conditioning tank 301, and is used to transport the grain discharged from the discharge port of the grain conditioning tank 301 to the carrying unit 1 along a specified path.

[0053] In this embodiment, the carrying unit 1 is used to carry grains. More specifically, the carrying unit 1 is used to carry the grains after they have been moistened, so as to facilitate moisture retention and transportation of the grains.

[0054] Specifically, in this embodiment, the carrying unit 1 specifically includes a tray 101, and the tray 101 is used to carry and stack food. Figure 3 The tray 101 is a circular disc-shaped structure, and the upper surface of the tray 101 is a horizontal bearing surface. Grains can be stacked horizontally on the bearing surface. The horizontal bearing surface can prevent moisture in the grain pile from being lost due to the uneven stacking surface, which is conducive to water retention. Of course, the shape of the tray 101 is not limited to this. For example, the shape of the tray 101 can also be square, oval, and other regular or irregular shapes.

[0055] Furthermore, in this embodiment, the carrying unit 1 includes a plurality of trays 101. Figure 1 Two pallets 101 are shown as an example, one pallet 101 is located in the loading area, and the other pallet 101 is located in the unloading area. The purpose of setting up multiple pallets 101 is to achieve sustainable operation of grain moistening. For example, after the pallet 101 is fully loaded, the empty pallet 101 can be switched to continue receiving materials, thereby achieving uninterrupted operation of grain moistening.

[0056] Furthermore, in this embodiment, the tray 101 is provided with an outer edge baffle 103 arranged along the edge contour thereof. Figure 3 , corresponding to the tray 101 with the circular disc structure, the outer edge baffle 103 is a circular ring structure and is installed on the circumference of the circular tray 101. In this way, the outer edge baffle 103 can prevent the spread of grain, so that the grain is piled on the tray 101 in a more concentrated cone shape, thereby increasing the grain carrying capacity of the tray 101; and the outer edge baffle 103 can prevent the moisture loss of the grain pile, which is beneficial to the water retention of the grain and allows the grain to fully absorb water.

[0057] Furthermore, participate Figure 3 A notch 104 is provided on one side of the outer baffle plate 103, through which the suction tube of the grain pumping machine 401 can be placed flat, and the grain can be pumped more effectively. Of course, in some embodiments, in order to prevent the grain from being scattered through the notch 104, a detachable or openable movable door (not shown in the figure) can also be provided at the notch 104. For example, the movable door is an arc-shaped plate matching the shape of the notch 104, and one side of the movable door is hinged to the outer baffle plate 103. When the grain needs to be piled, the movable door is closed, and when the grain needs to be pumped, the movable door is opened.

[0058] For further information, see Figure 3 A base frame 102 is provided at the bottom of the pallet 101, and the base frame 102 supports the pallet 101 off the ground, so as to facilitate the transportation of the pallet 101 by tools such as forklifts.

[0059] The grain moistening system provided by the embodiment of the utility model has the following operating principles:

[0060] The first grain moistening: the grain pumping machine 401 pumps the raw grain evenly to the upper hopper 402 and introduces it into the grain moistening tank 301. At the same time, start the pump, open the valve 204, pump hot water into the grain moistening tank 301, start the drive motor 304 to drive the grain moistening tank 301 to rotate, and the grain pumping, watering and grain moistening tank 301 work simultaneously to moisten the grain. After the grain moistening is completed, the grain pumping machine 401, the pump and the drive motor 304 are turned off, and the discharge port of the grain moistening tank 301 is opened. The grain is transported to the pallet 101 through the lower hopper 403 for stacking, and then the pallet 101 is transferred to the planned placement point by a forklift.

[0061] Second and third grain moistening: Use a forklift to transfer the moistened grain pile to the suction pipe of the grain pump 401, and then repeat the first grain moistening operation.

[0062] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
