TECHNICAL FIELD

[0001] The utility model relates to liquor koji making production equipment technical field, especially a koji making grain moistening system. BACKGROUND

[0002] After the wheat is moistened, a flour mill grinds it, and the ground wheat is mixed with mother koji and water in a proportion, and then is manually stepped into a shape, and the koji block is sent to a fermentation bin for fermentation. The moistening makes the wheat bran absorb a certain amount of water, and the bran is soft and has a certain ductility. After grinding, there are more pieces of skin and fewer particles, which is more in line with the requirements of rotten core and not rotten skin in Daqu production. Moistening is a key step in koji making process. The difference in moisture content of wheat and the amount of added water have a great influence on moistening. Therefore, the change in moisture content needs to be accurately grasped and the amount of added water needs to be adjusted in real time in production. In the existing production mode, the amount of added water needs to be determined by human judgment, and there are too many uncertain factors, so the quality cannot be well guaranteed. SUMMARY

DETAILED DESCRIPTION

[0022] Example 1:

[0023] For example Figs. 1-4As shown, a system for preparing koji and moistening grains includes a mixer 1, which is a powerful horizontal mixer for mixing wheat and water, and a feed inlet of the mixer 1 is connected with a feed outlet of a screw metering scale 4 arranged at an outlet of a wheat metering bin 3 through a feed pipe 2, and the wheat metered by the screw metering scale 4 after being discharged from the wheat metering bin 3 is transported into the mixer 1.

[0024] The system further includes a water adding machine 5 for providing a stable and constant water source. The water adding machine 5 includes a water storage tank 501, which is connected with an outlet pipeline 502, a water return pipeline 503 and a water supplement pipeline 504, and the water supplement pipeline 504 is used for connecting with an external pipeline to supply water to the water storage tank 501. In specific use, a water inlet pneumatic angle valve is arranged on the water supplement pipeline 504 to control water supplement.

[0025] The outlet pipeline 502 is connected with a water supply pump 505, an electromagnetic flowmeter 506 and an adjusting valve 507, the adjusting valve 507 is a pneumatic proportional adjusting valve and is a main functional component for accurately controlling water adding amount, and automatically controls according to a PLC input instruction with a control precision error ≤3‰. The electromagnetic flowmeter 506 is a main functional component for detecting water adding amount and has a detection precision error ≤3‰.

[0026] In specific use, the water adding machine 5 further includes a control assembly, which is a PLC controller and is used for analyzing and processing commands from a man-machine interactive control assembly to control operation of each component of the water adding machine.

[0027] Preferably, the water storage tank 501 is provided with a pressure transmitter 508. The pressure transmitter 508 located at the bottom of the water tank gives different signals according to water level, which facilitates control of water amount in the water storage tank 501.

[0028] The outlet pipeline 502 is provided with a filter 509, and water in the water storage tank 501 is filtered by the filter 509 before being transported to the mixer 1 through a pipeline system, so as to reduce impurity content in the water and prevent impurities from affecting quality of the koji material.

[0029] An outlet of the outlet pipeline 502 is connected with an inlet of a three-way valve 7 through a water adding pipe 6, one outlet of the three-way valve 7 is connected with a water adding inlet of the mixer 1 through a grain moistening water adding pipe 8, another outlet of the three-way valve 7 is connected with a pipe opening of the water return pipeline 503 through a water return pipeline 9, the three-way valve 7 is fixed on the mixer 1 or a mounting column 10 at one side of the mixer 1, and the three-way valve 7 is located near the water adding inlet of the mixer 1 and is less than 300 mm.

[0030] The three-way valve 7 is a pneumatic three-way reversing valve, which switches water from the water adding pipe 6 to the grain moistening water adding pipe 8 or the water return pipeline 9 to realize switching between a water adding state and a preparation adjusting state.

[0031] The three-way valve 7 is located near the water inlet of the mixer 1. When the water adding machine 5 is started and no water adding instruction is obtained, the three-way valve 7 is switched to the backwater pipeline 9, and the storage tank 501, the outlet pipeline 502, the water adding pipeline 6, the backwater pipeline 9, and the backwater pipe 503 form a communication loop. At this time, it is in the water flow regulation state and is standby. When the water adding instruction is obtained, the three-way valve 7 is switched to the grain moistening water adding pipeline 8 to supply water to the mixer 1. Since the three-way valve 7 is located near the water inlet of the mixer 1, the water flow time in the water adding pipeline 6 can be ignored, so the water adding instruction can be obtained to realize that the material and the water flow enter the mixer 1 at the same time for mixing and stirring, and no control delay error is generated.

[0032] Preferably, the discharge pipe 2 is provided with a moisture detector 11 for measuring the water content of the added wheat to provide a data source for subsequent automatic proportioning.

[0033] Embodiment 2:

[0034] Different from embodiment 1, the mounting column 10 is provided with a control screen 13 through a connecting mechanism 12. The control screen 13 is an interactive interface of a human-computer interaction control component, and is used for controlling the mixer 1, the spiral metering scale 4, the three-way valve 7, and the water adding machine 5.

[0035] The connecting mechanism 12 includes a mounting seat 1201 arranged on the mounting column 10, and a mounting frame 1202 provided with a rotating shaft 1203 at one end. The rotating shaft 1203 is rotatably arranged on the mounting seat 1201 through a bearing, and the control screen 13 is arranged on the mounting frame 1202. The mounting frame 1202 has an “L” shape structure. The position of the control screen 13 is adjusted by rotating the mounting frame 1202 along the rotating shaft 1203. Since the distance between the mounting column 10 and the mixer 1 is relatively short, the angle of the control screen 13 relative to the mounting column 10 is adjusted to facilitate operation.

[0036] The working process of the system is as follows:

[0037] First, the outside water source enters the water storage tank 501 through the water supplement pipe 504, when the water adding machine 5 is started and no water adding instruction is obtained, the three-way valve 7 is switched to the water return pipeline 9, the water storage tank 501, the outlet pipeline 502, the water adding pipe 6, the water return pipeline 9 and the water return pipe 503 form a communication loop, at this time, it is in the water flow regulating state, and it is standby; when the water adding instruction is obtained, the three-way valve 7 is switched to the grain moistening and water adding pipe 8 to supply water to the mixing machine 1. Since the three-way valve 7 is located near the water adding port of the mixing machine 1, the water flow time in the water adding pipe 6 can be ignored, so after the water adding instruction is obtained, the material and the water flow can be simultaneously introduced into the mixing machine 1 to mix and stir, and the control delay error is not caused. The wheat in the wheat metering bin 3 is weighed by the screw metering scale 4 and is conveyed to the mixing machine 1 after being discharged, during the wheat discharging process, the water content detector 11 is used to measure the water content of the added wheat, the water adding proportioning amount is calculated according to the water content of the wheat, the control assembly of the water adding machine 5 gives an instruction to the regulating valve 507 to control the water flow to obtain a matched flow.
