Description

Technical Field

[0001] The present invention relates to the technical field of wine making, and in particular to an all-in-one machine for steaming grain, spreading grain and mixing koji. Background Art

[0002] In the traditional process of brewing, the grains need to be crushed first, and then cooked at high temperature to make them fully cooked. After this step is completed, the next step is to spread them out for cooling. This step requires workers to manually take the steamed grains out of the cooking equipment and spread them evenly on the ground so that they can cool naturally. Workers usually hold shovels or other tools to repeatedly turn and spread the grains to ensure that they can dissipate heat evenly and quickly. After the grain temperature drops to a suitable range, the subsequent mixing of the koji is carried out to prepare for the fermentation process.

[0003] However, with the continuous advancement and development of automation technology, the production efficiency of the brewing industry has also been significantly improved. Chinese patent CN219670457U discloses a steamed grain cooling machine designed specifically for brewing. The equipment is more accurately defined as a special cooling equipment, rather than a comprehensive equipment that has both steaming and cooling functions. When it is necessary to steam grains, since the machine is equipped with stirring components for the cooling process, these components will interfere with the normal buckling of the lid of the cooking equipment, resulting in the inability to form a closed cooking environment. In addition, the presence of the stirring component also brings certain inconveniences to the grain discharge process after cooling.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention is further described in combination with the drawings and embodiments:

[0031] like Figure 1-Figure 3 As shown, a grain steaming, grain spreading and koji mixing all-in-one machine comprises a cabinet 100, rectangular frames 4 are slidably matched on both sides of the cabinet, a fixed plate 2 is provided in the middle of the cabinet, a lifting mechanism 5 is installed on the fixed plate, the lifting mechanism is connected to the rectangular frame, a horizontal moving mechanism is provided on the rectangular frame, a driving motor 74 is installed on the horizontal moving mechanism, the driving motor is connected to the stirring mechanism, a fan 1 is installed on the cabinet, a middle partition 101 is formed in the cabinet, and a plurality of through holes 102 are provided on the middle partition. This design enables the all-in-one machine to integrate the functions of grain steaming, cooling and koji mixing, thereby improving the utilization rate and production efficiency of the equipment.

[0032] Furthermore, the fan is connected to the cabinet through an air pipe, and a control valve is provided on the air pipe. The design of the fan and the control valve can flexibly adjust the airflow and effectively accelerate the cooling process of the grain.

[0033] Working mode: This cabinet is an existing technology and has been widely used in the industry. A drying cloth can be placed on the middle partition of the cabinet, and rice or other grains can be placed on the drying cloth. Cold water is stored at the bottom of the middle partition. A water inlet pipe is provided at the bottom of the cabinet for water to enter and discharge. A heating pipe is provided in the cabinet for steaming grains. When it is necessary to steam grains, Figure 1 and Figure 2As shown, there is a gap between the right side of the rectangular frame and the cabinet. After the driving mechanism and the stirring mechanism can move to the gap, the lifting mechanism moves down, so that the rectangular frame moves vertically below the upper surface of the cabinet, thereby avoiding interference with the steamed grain. The stirring rod of the stirring mechanism is disassembled at this point, which can effectively reduce the storage space of the stirring mechanism. People can conveniently put rice in the cabinet, then cover the lid and steam the grain. After the grain is steamed, the water in the cabinet is discharged to the outside, and the lid of the steamed grain is opened. At this time, the control valve on the air pipe is opened, and the fan is started. The fan blows the airflow out from the through hole of the middle partition. In this process, the lifting mechanism drives the rectangular frame to move upward, the horizontal moving mechanism drives the driving mechanism to move horizontally, and the driving mechanism drives the stirring mechanism to stir the cooked grain for cooling. The stirring mechanism can also be used to mix the koji later.

[0034] In at least one embodiment, the rectangular frame includes a front plate 41, a rear plate 42, a left plate 43 and a right plate 44, which are spliced ​​to form a quadrilateral bracket, a vertical slide rail 31 is provided on the cabinet, a vertical slider 32 is slidably matched on the slide rail, and vertical sliders are installed on both the left plate and the right plate, and the rectangular frame can slide up and down along the vertical slide rail. The design of the rectangular frame and the vertical slide rail enables the stirring mechanism to move up and down flexibly to meet different work requirements.

[0035] In at least one embodiment, the lifting mechanism is an electric cylinder, which is fixedly connected to a fixed plate, and a telescopic rod of the electric cylinder passes through the fixed plate and is connected to a rectangular frame. As a lifting mechanism, the electric cylinder provides stable and precise lifting control, thereby improving the automation of the equipment.

[0036] In at least one embodiment, the bottom of the cabinet is provided with supporting legs.

[0037] In at least one embodiment, a control panel 6 (containing a PLC controller) is installed on the cabinet. The design of the control panel and the PLC controller makes the equipment operation easier and realizes intelligent control.

[0038] In at least one embodiment, Figure 3 and Figure 8As shown, the horizontal mechanism includes a horizontal slide rail 71, a horizontal slider is slidably fitted on the horizontal slide rail, a support plate 72 is fixedly connected to the horizontal slider, a first synchronous pulley 82 and a second synchronous pulley 84 are rotatably connected to the front plate and the rear plate respectively, the first synchronous pulley 82 and the second synchronous pulley are driven and connected by a synchronous belt 83, the bottom of the support plate is fixedly connected to the synchronous belt by a buckle, a rotating motor 81 is installed on the rectangular frame, and the output shaft of the rotating motor is connected to the first synchronous pulley. The rotation of the rotating motor can drive the support plate to move along the horizontal slide rail. The design of the horizontal moving mechanism and the rotating motor enables the stirring mechanism to move horizontally, expanding the working range of the equipment.

[0039] Furthermore, a stirring mechanism is installed on the two support plates, and a driving motor is provided on the support plates, and the driving motor is connected to the stirring mechanism.

[0040] In some embodiments, a supporting connecting plate is provided between the two supporting plates. The design of the supporting connecting plate enhances the stability of the supporting plates and improves the overall structural strength of the equipment.

[0041] In at least one embodiment, Figure 3 As shown, the stirring mechanism includes a stirring shaft 73, on which are provided a plurality of fixing rings 76, on which are provided a plurality of threaded holes, in which the threaded holes are threadedly connected a stirring rod 75. This design allows the stirring rod to be easily installed and removed, thereby improving the maintainability and flexibility of the equipment.

[0042] In at least one embodiment, Figure 4 As shown, the stirring mechanism includes a stirring shaft 73 and a plug-in screw 91, the stirring shaft is provided with a plurality of fixing rings 76, the fixing ring is provided with a plurality of through holes 761, a stirring rod 75 is inserted in the through hole, the stirring rod is provided with a horizontal hole 751, the fixing ring is provided with a plurality of plug-in holes matching the horizontal holes, the plug-in screw sequentially passes through the through hole on the fixing ring and the horizontal hole on the stirring rod and is fastened by a left tightening nut 92 and a right tightening nut 93. This design can quickly fix the stirring rod without tightening each stirring rod on the fixing ring. The design of the plug-in screw and the left tightening nut and the right tightening nut makes the fixing of the stirring rod faster and more secure, and improves the working efficiency of the equipment.

[0043] The solution is refined, the left tightening nut 92 and the right tightening nut 93 are respectively located at both ends of the plug-in screw.

[0045] Furthermore, a semicircular slot is formed on the snap-in plate to facilitate the positioning of the stirring rod. The positioning of the stirring rod is achieved by using the snap-in plate design. When people remove the snap-in plate, the four stirring rods can be changed from being 90° apart from each other to being fitted together, reducing the occupied volume, thereby facilitating the stirring mechanism to enter the gap between the right side of the rectangular frame and the cabinet.

[0046] Working mode: Check whether all parts of the machine are intact, and ensure that the lifting mechanism, horizontal movement mechanism, stirring mechanism, fan, etc. are working properly. Prepare the appropriate amount of grain and water according to the type and quantity of grain to be steamed.

[0047] Lay the drying cloth on the middle partition, and then place the grain (such as rice) evenly on the drying cloth. Pour an appropriate amount of water into the bottom of the cabinet to ensure that the water level is below the middle partition. Cover the cabinet lid and start the heating tube to steam the grain. During the steaming process, the rectangular frame and the stirring mechanism move to the gap on the right side of the cabinet to avoid interference.

[0048] After the grain is steamed, drain the water from the cabinet. Open the cabinet cover, start the fan, and open the control valve on the air pipe to blow air out from the through hole of the middle partition to accelerate the cooling of the grain. At the same time, the lifting mechanism drives the rectangular frame to move upward, and the horizontal moving mechanism drives the stirring mechanism to move above the grain. The driving mechanism starts, and the stirring mechanism begins to stir the cooked grain to further promote cooling.

[0049] Koji mixing stage (if necessary): Add koji materials as needed during or after the cooling process. Continue to use the stirring mechanism to mix the koji to ensure that the koji materials and grain are evenly mixed. After the koji mixing is completed, turn off all equipment and take out the grain for subsequent processing. Clean the inside of the cabinet, drying cloth, stirring mechanism and other parts to keep the equipment clean.
