Description

Technical Field

[0001] The present disclosure relates to wine-making equipment, and more particularly, to a grain moistening system. Background Art

[0002] Grain moistening is one of the key processes in the brewing of Maotai-flavor liquor. The moisture content of grain has an important impact on the subsequent processes. The higher the moisture content in the grain, the more conducive it is to removing the raw taste in the grain and ensuring the purity of the grain aroma. Therefore, the moisture content of the grain is the key to the distillation process and directly affects the aroma and taste of the liquor.

[0003] The moisture of grain is replenished by moistening the grain, that is, before the grain is mixed with the fermented grain, hot water is used to sprinkle the grain to replenish the moisture for the grain, and the grain that absorbs the hot water is spread out to emit the fresh smell in the grain and maintain the pure grain aroma of the grain. The water content can be increased by using a secondary moistening process. For example, CN 105602782A discloses a method for secondary moistening of grain to increase the moisture content of grain and improve the gelatinization effect. However, most of the current moistening processes still use manual work, that is, the grain is piled on the ground, hot water is poured in manually, and then the grain is turned and mixed manually with a shovel. This method of moistening the grain has low production efficiency, poor working environment, high labor intensity, long working hours, and it is difficult to ensure sanitary conditions.

[0004] In order to solve the above problems, patent document CN 205132581U discloses a sauce-flavored grain moistening machine, including a temporary storage feeder and a spiral grain moistening machine, wherein the temporary storage feeder includes a bin and a variable frequency speed regulating roller arranged at the bottom of the bin, a spiral grain moistening machine is arranged at the lower part of the variable frequency speed regulating roller, and a water spraying device is arranged above the spiral grain moistening machine. The grain moistening machine adopts mechatronic equipment to replace manual labor, improve the working environment, and realize continuous production. However, it still has some shortcomings: first, it is difficult to achieve uniform grain moistening through the rotation of the spiral grain moistening machine and the water distribution of the water spraying device; second, the grain is rotated and transported to the next process after being sprayed with water, and the grain is not thoroughly moistened, and the moistening effect is not good. Summary of the invention

[0005] In order to at least partially overcome the above-mentioned problems existing in the prior art, the present disclosure provides a grain moistening system, which can automatically realize two watering and two grain moistening, moisten the grain evenly, and can improve the water content and cooking gelatinization effect of the grain after moistening.

DETAILED DESCRIPTION

[0018] The grain moistening system disclosed in the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following detailed description and claims. It should be noted that the accompanying drawings are in a very simplified form and use non-precise ratios, which are only used for the purpose of conveniently and clearly assisting in explaining the embodiments of the present invention.

[0019] The grain moistening system according to an embodiment of the present disclosure is described below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a grain moistening system, including a track unit, a grain moistening unit running on the track unit, a watering unit and a transfer unit arranged above the track unit, and a receiving spiral mechanism 1. The receiving spiral mechanism 1 can be arranged at one end of the track unit, and can be implemented as a suitable type of screw conveyor. Among them, the receiving spiral mechanism 1 receives a certain amount of grain, and transports the grain to the watering unit to achieve the first watering of the grain. The watering unit transports the watered grain to the grain moistening unit (including multiple grain moistening hoppers 4) to achieve the first moistening of the grain, and the transfer unit realizes the turning of the box (i.e., turning over the grain moistening hopper 4), and then transports the grain to the watering unit to achieve the second watering, and then the second moistening of the grain is achieved through the grain moistening unit. By using the grain moistening hoppers arranged on multiple tracks in conjunction with the drum watering machine, two watering and two grain moistening are achieved, ensuring that the grain is fully and evenly moistened, the grain has sufficient moisture, and the grain flavor is pure.

[0021] like Figure 1 and Figure 2 As shown, the track unit includes a plurality of tracks that are crisscrossed, preferably four vertical and two horizontal tracks (not limited to Figure 2). Wherein, each vertical and horizontal intersection may be provided with a steering chain path 7. The steering chain path 7 may include a driving mechanism, which may drive the steering chain path 7 to rotate, thereby driving the grain moistening hopper 4 located thereon to rotate, for example, by an angle of 90 degrees, so as to change the running direction of the grain moistening hopper 4 and realize the steering of the grain moistening hopper 4. A cloth chain path 8 is provided at the watering unit, and other positions are grain moistening buffer chain paths 9. The cloth chain path 8 and the grain moistening buffer chain path 9 may be implemented in the same manner, having the same or largely similar structures and functions. The grain moistening unit may run on the grain moistening buffer chain path 9 and the cloth chain path 8, specifically, the cloth chain path 8 is configured to allow an empty grain moistening hopper 4 to run thereon, and the grain moistening buffer chain path 9 is configured to allow the grain moistening hopper 4 with grain therein to be filled therein, and to realize steering through the steering chain path 7, thereby realizing two watering and two grain moistening cycle operations.

[0022] Alternatively, the grain moistening hopper 4 includes a walking mechanism, which drives the grain moistening hopper 4 on the track unit, especially along the grain moistening buffer chain 9 and the material distribution chain 8. In particular, the walking mechanism can be implemented to include a drive and a toothed wheel, which cooperates with the chain and can move along the chain.

[0023] Alternatively, those skilled in the art should understand that the grain moistening buffer chain path 9 and the material distribution chain path 8 can be configured to drive the grain moistening hopper 4 to move on the track unit.

[0024] The two grain moistenings require a certain interval. After the first watering, the grain moistening bucket 4 stays on the grain moistening cache chain 9 for a period of time, for example, Figure 2 After the second watering, the grain moistening bucket 4 also stays on the grain moistening buffer chain 9 for a period of time, for example, Figure 2 The "Er Run" in the grain hopper is in the position shown.

[0025] like Figure 1 and Figure 2 As shown, above the track unit, adjacent to the receiving spiral mechanism 1, a plurality of watering units are provided, preferably two watering units, which are respectively provided on two longitudinal chain tracks to improve production efficiency. The watering unit includes a rolling watering machine 2 and a grain moistening watering device 3, which are connected by a pipeline. Among them, the rolling watering machine 2 is provided on the top of the grain moistening hopper 4 and circulates. The grain enters the rolling watering machine 2 through the receiving spiral mechanism 1 and rotates with it. The rolling watering machine 2 is provided with a nozzle to spray hot water in real time. While the grain rotates with the rolling watering machine 2, it is fully in contact with the hot water, and after being evenly mixed, it enters the grain moistening hopper 4 for transportation. The next grain moistening hopper 4 quickly fills the position to receive the moistened grain, and the cycle is repeated to achieve full and even grain moistening.

[0026] Preferably, the grain and water are accurately measured to achieve the purpose of accurate proportioning and precise grain moistening.

[0027] Preferably, the rolling dampener 2 adopts a horizontal rotary cylinder structure to minimize the damage to the grain during the rotation process.

[0028] In addition, at both ends of the track unit, a transfer unit is provided, which includes a box turning mechanism and a second moistening conveyor 6. Among them, the box turning mechanism includes a lifting box turning machine 10, a box turning discharge hopper 5 and a grain receiving hopper 11. The lifting box turning machine 10 may include a lifting mechanism and a turning mechanism known in the art to realize the box turning function. After the first moistening of the grain is completed, the grain moistening hopper 4 moves to the lifting box turning machine 10, and the box is lifted and turned by the lifting box turning machine 10. The moistened grain in the grain moistening hopper 4 is poured into the grain receiving hopper 11, and enters the box turning discharge hopper 5, and enters the receiving spiral mechanism 1 through the second moistening conveyor 6 for a second grain moistening process. The receiving spiral mechanism 1 can extend from above the watering unit to below the second moistening conveyor 6 in the longitudinal direction.

[0029] The secondary grain moistening process can be implemented similarly to the primary grain moistening process. The grain reenters the watering unit and is moistened for the second time through the watering unit, and then moistened for the second time through the grain moistening unit. After the secondary grain moistening is completed, the grain moistening hopper 4 is lifted and turned over by the box turning machine 10, and the box turning discharge hopper 5 receives the second grain moistening and discharges the grain. The grain moistening is completed and discharged.

[0030] like Figure 3 As shown, the grain moistening water adder 3 delivers hot water to the meter through a motor, and controls the front-end valve of the meter to add hot water to the rolling dampeners 2 of multiple dampening units, such as the first rolling dampener and the second drum dampener. The first and second rolling dampeners are the corresponding rolling dampeners of the two dampening units. Alternatively, a heater or the like may be provided in the grain moistening water adder 3.
