Abstract
Description
Technical Field
[0001] This utility model relates to the field of brewing technology, specifically to an automatic control system for brewing rice husks. Background Technology
[0002] Rice husks, as an excellent auxiliary material in baijiu brewing, play a role in loosening and regulating the density of the mash, which is beneficial for subsequent distillation and fermentation. However, in terms of rice husk management, the dried rice husks in traditional baijiu brewing processes are easily affected by temperature and humidity, causing changes in their gas and chemical composition, affecting their water absorption and the support of their microporous structure, leading to problems such as caking and mold growth. Furthermore, the timing and amount of rice husks added during brewing are difficult to control precisely, resulting in significant deviations in the matching ratio of rice husks with the mash and sorghum, affecting subsequent distillation efficiency and the quality of the distillate. Moreover, the labor intensity for workers is high, and rice husk management is difficult to control. Regarding rice husk distribution, dried rice husks are usually transported using short-distance conveyor belts, as shown in patent application CN104293588. The temperature control and distribution amount of rice husks during this process rely on worker experience, and the distribution process affects the physical properties of the rice husks, making it difficult to effectively control the breakage rate. Utility Model Content
[0003] The present invention aims to provide an automatic control system for brewing rice husks, which can provide a system that can conduct closed transfer and transportation of rice husks to ensure the quality of rice husks.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: an automatic control system for brewing chaff, including a control system and a spreading and drying system, a temporary storage and distributing system, a transfer device, and a closed transfer system, which are sequentially arranged and electrically connected to the control system. The temporary storage and distributing system includes at least one distributing group, each of which includes a cylindrical silo and a weighing and distributing device connected to the outlet of the cylindrical silo. The closed transfer system includes a closed conveying corridor and at least one mixing mechanism connected to the outlet of the closed conveying corridor. The inlet of the closed conveying corridor is connected to the weighing and distributing device through the transfer device. A sensor detection system is installed inside the closed conveying corridor, including a humidity sensor.
[0005] The beneficial effects of this plan are:
[0006] By using enclosed transport corridors for transfer, the rice husks are protected from external environmental influences (such as humidity, temperature, and pollution) during transport, thus ensuring their absorbency and microporous structure remain intact and preventing caking and mold growth to some extent. The enclosed transport corridors also reduce the exposure time of the rice husks, lowering the possibility of external contamination and minimizing contact between the husks and external dust.
[0007] By combining a cylindrical silo with a weighing and dispensing device, quantitative distribution of rice bran husks is achieved, ensuring precise feeding amounts, stable husk quality, and accurate dispensing ratios. This improves the efficiency of the distillation process, increases the yield, and enhances the consistency of the spirit. Furthermore, this technical solution is equipped with a sensor detection system to monitor the husk condition in real time during transport, enabling the detection of anomalies and timely adjustments to ensure the husks are in optimal condition before use. The system design is highly compatible, adaptable to the needs of brewing at different scales, and contributes to modern, large-scale production.
[0008] Preferably, as an improvement, the temporary storage and distribution system includes at least two distribution groups, each equipped with a level gauge on the inner wall of the silo, which can send the rice husk level information to the control system.
[0009] The beneficial effects are as follows: the material level gauge on the inner wall of the cylindrical silo can feed back the rice husk height information to the control system in real time, so as to keep track of the remaining amount in each cylindrical silo, ensure the transparency of the inventory, and avoid a certain silo being too full or too empty. The control system can automatically arrange the material distribution sequence according to the fermentation and distillation progress, so as to avoid the rice husks in a single cylindrical silo from accumulating and caking over a long period of time.
[0010] Preferably, as an improvement, each silo is equipped with a temperature and humidity monitoring system, which includes multiple arrays of temperature sensors, humidity sensors, and dew point transmitters that are electrically connected to the control system within the silo.
[0011] The beneficial effects are: by timely detection of humidity or dew point abnormalities, staff can be reminded to take measures such as ventilation, dehumidification or heating to keep the rice husks dry and loose, reduce the risk of mold growth and caking, ensure that the rice husks are always in the best storage condition, and improve their water absorption and microporous structure stability.
[0012] Preferably, as an improvement, the weighing and distributing equipment includes a buffer hopper, a feeding solenoid valve, a storage chamber, and a weighing scale for weighing the rice husks in the storage chamber. The feeding solenoid valve is located at the outlet end of the buffer hopper and is connected to the inlet end of the storage chamber. The outlet end of the storage chamber is also equipped with a discharge valve.
[0013] The beneficial effects are as follows: the buffer hopper can be used to temporarily store and evenly release rice husks, so that when the downstream feeding solenoid valve is opened, the rice husks will not overflow or become blocked, ensuring a stable flow rate. By setting a weighing scale to accurately weigh the rice husks in the storage chamber, it is easy to feed in a quantitative manner, so that the weight of rice husks taken each time is kept within the set error range, ensuring a stable ratio with raw materials such as lees and sorghum, which in turn is beneficial to the distillation efficiency and the stability of the liquor quality.
[0014] Preferably, as an improvement, the spreading system includes spreading equipment, belt conveyor equipment, and bucket elevator. The inlet end of the belt conveyor equipment is connected to the outlet end of the spreading equipment, the inlet end of the bucket elevator is connected to the outlet end of the belt conveyor equipment, and the outlet end of the bucket elevator is connected to the inlet end of the silo.
[0015] The beneficial effects are as follows: the belt conveyor and the bucket elevator form an assembly line operation, directly transporting the rice husks to the silo entrance after they have been spread out to dry, eliminating the need for manual handling, preventing secondary contact and material loss in the intermediate links, and improving the continuity of the production rhythm. The belt conveyor transports the rice husks in a smooth horizontal movement, which can effectively avoid breakage caused by the rolling and collision of particles. During the vertical conveying process, the bucket elevator uses a single bucket to carry the rice husks, preventing them from piling up and being squeezed in large quantities during the lifting process, further reducing the rice husk breakage rate.
[0016] Preferably, as an improvement, the enclosed conveyor corridor includes multiple sets of sealed belt conveyors connected end to end.
[0017] The beneficial effects are: it can effectively prevent rice husks from falling and block dust from entering the air, and the sealed structure can better maintain the temperature and humidity conditions in the conveying channel, reduce the impact of external environmental changes on the moisture absorption and microporous structure of rice husks, and reduce the risk of rice husks sticking or caking due to condensation caused by temperature differences.
[0018] Preferably, as an improvement, the sensor detection system also includes a multispectral sensor, a temperature sensor, and an audio sensor installed in the sealed belt conveyor. The multispectral sensor, temperature sensor, humidity sensor, and audio sensor are all electrically connected to the control system, which can control the conveying speed of the sealed belt conveyor.
[0019] The beneficial effects are as follows: Multispectral sensors can detect spectral information such as color and reflectivity of rice husks during transportation, which can be used to identify impurities, mold, or abnormal moisture content; temperature and humidity sensors simultaneously monitor environmental parameters to detect potential risks of localized overheating or dampness; sound sensors can capture collision and friction sounds during transportation, and quickly determine whether rice husks are damaged or jammed through spectrum analysis. When abnormal high-frequency noise is detected, the speed of the sealed belt conveyor is adjusted to reduce the possibility of rice husk collision and damage. Through multi-dimensional, real-time monitoring and intelligent linkage, the sensor detection system can not only proactively protect the integrity of rice husks and ensure material quality during transportation, but also optimize equipment operation and maintenance.
[0020] Preferably, as an improvement, the mixing mechanism includes a temporary storage bin and a spiral mixing conveyor connected to the outlet end of the temporary storage bin. The outlet end of the enclosed conveying corridor is connected to the inlet end of the mixing mechanism. A level gauge is also provided in the temporary storage bin, which can send the rice husk level information to the control system.
[0021] The beneficial effects are as follows: The mixing mechanism includes a temporary storage bin and a spiral mixing conveyor connected to the outlet end of the temporary storage bin. The outlet end of the enclosed conveying corridor is connected to the inlet end of the mixing mechanism. A level gauge is also installed in the temporary storage bin. The level gauge can send the rice husk level information to the control system, which facilitates the system to call up the set amount of rice husk at any time.
[0022] Preferably, as an improvement, the bottom of the silo is provided with a vibration loosening device, which can drive the silo to vibrate at a set frequency.
[0023] The beneficial effects are as follows: the vibration loosening equipment can periodically vibrate the bottom of the silo at a set frequency. In particular, when the humidity is detected to be close to the preset mold risk threshold, the vibration loosening equipment can be activated to effectively prevent the caking caused by long-term accumulation of rice husks, ensuring that the material always remains in a loose state, while improving the smoothness of discharge.
[0024] Preferably, as an improvement, the top of the silo is equipped with a ventilation fan capable of exhausting the air inside the silo.
[0025] The beneficial effect is that it helps to expel humid air from the warehouse and keep the humidity within a normal range. Attached Figure Description

[0029] The following detailed description is provided through specific implementation methods and examples:
[0030] The preferred embodiments of this utility model are basically as shown in the appendix. Figure 1-2 As shown, Figure 1 and Figure 2The automatic control system for brewing rice husks shown includes a control system and a spreading system, a temporary storage and distribution system, a transfer device, and a closed transfer system, which are sequentially arranged and electrically connected to the control system. The temporary storage and distribution system includes at least one distribution group, each of which includes a cylindrical silo 2 and a weighing and distribution device 3 connected to the outlet end of the cylindrical silo 2. The closed transfer system includes a closed conveying corridor 12 and at least one mixing mechanism 4 connected to the outlet end of the closed conveying corridor 12. The inlet end of the closed conveying corridor 12 is connected to the weighing and distribution device 3 through the transfer device. The closed conveying corridor 12 is equipped with a sensor detection system. To make the structure simple, reliable, and easy to assemble, the transfer device includes a bucket elevator. In the preferred embodiment of this invention, the closed conveying corridor 12 includes multiple sets of sealed belt conveyors connected end to end, which facilitates continuous rice husk transportation. To ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention includes a temporary storage and distribution system comprising at least two distribution groups. Each cylindrical silo 2 is equipped with a level gauge on its inner wall. The level gauge is electrically connected to the control system, and can provide real-time feedback of the rice husk height information to the control system. This allows for real-time monitoring of the remaining amount in each cylindrical silo 2, ensuring transparent inventory status and preventing any silo from being too full or too empty. The control system can automatically arrange the distribution sequence according to the fermentation and distillation progress, preventing long-term accumulation of rice husks in a single cylindrical silo 2 that could lead to caking.
[0031] By using a sealed conveyor corridor 12 for transfer, the rice husks are protected from external environmental influences (such as humidity, temperature, and pollution) during transport, thus ensuring their absorbency and microporous structure remain intact and preventing caking and mold growth to some extent. The sealed conveyor corridor 12 reduces the exposure time of the rice husks, lowering the possibility of external contamination and minimizing contact with dust. The combination of a cylindrical silo 2 and a weighing and distributing device 3 enables quantitative distribution of the rice husks, ensuring accurate feeding amounts, stable quality, and precise distribution ratios. This improves the efficiency of the distillation process, increases the yield, and enhances the consistency of the alcohol. Furthermore, this technical solution is equipped with a sensor detection system to monitor the rice husk condition in real time during transport, enabling the detection of anomalies and timely adjustments to ensure the rice husks are in optimal condition before use. The system design is highly compatible, adaptable to different scales of brewing needs, and contributes to modern, large-scale production.
[0032] To ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention includes a temperature and humidity monitoring system within each cylindrical silo 2. This system comprises multiple arrays of temperature sensors, humidity sensors, and dew point transmitters electrically connected to the control system. The temperature sensors, humidity sensors, and dew point transmitters transmit temperature, humidity, and dew point information to the control system, respectively. By promptly detecting humidity or dew point anomalies, the system alerts staff to take measures to keep the rice husks dry and loose, reducing the risk of mold growth and caking, ensuring the rice husks are always in optimal storage condition, and improving their water absorption and microporous structure stability. To further ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention includes a vibration loosening device at the bottom of the cylindrical silo 2. This device drives the cylindrical silo 2 to vibrate at a set frequency. The vibratory loosening equipment periodically vibrates the bottom of the cylindrical silo 2 at a set frequency. Especially when the humidity is detected to be close to the preset mold risk threshold, activating the vibratory loosening equipment effectively prevents the chaff from accumulating and hardening, ensuring the material remains loose and improving discharge smoothness. The top of the cylindrical silo 2 is equipped with a ventilation fan to expel air from the silo. This helps to remove humid air from the silo and maintain humidity within a normal range.

The outlet end of the storage chamber 5 is also equipped with a discharge valve. The weighing scale 9 weighs the rice husks in the storage chamber 5. The buffer hopper 6 can be used to temporarily store and evenly release the rice husks, ensuring that when the downstream feeding solenoid valve 7 is opened, the rice husks will not overflow or become blocked instantaneously, thus ensuring a stable flow rate. By setting the weighing scale 9 to accurately weigh the rice husks in the storage chamber 5, quantitative feeding is facilitated, ensuring that the weight of the rice husks taken each time remains within the set error range, guaranteeing a stable ratio with raw materials such as lees and sorghum, which in turn is beneficial to distillation efficiency and stable liquor quality.
[0034] To ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention comprises a spreading system including a spreading device 1, a belt conveyor 10, and a bucket elevator 11. The inlet end of the belt conveyor 10 is connected to the outlet end of the spreading device 1, the inlet end of the bucket elevator 11 is connected to the outlet end of the belt conveyor 10, and the outlet end of the bucket elevator 11 is connected to the inlet end of the cylindrical silo 2. The belt conveyor 10 and the bucket elevator 11 form a continuous production line, directly conveying the rice husks to the inlet of the cylindrical silo 2 after spreading, eliminating the need for manual handling, preventing secondary contact and material loss in intermediate stages, and improving the continuity of production. The belt conveyor transports the rice husks in a smooth, horizontal manner, effectively avoiding breakage caused by the rolling and collision of particles. During vertical conveying, the bucket elevator 11 uses a single-bucket carrying method to prevent the rice husks from piling up and being compressed during the lifting process, further reducing the rice husk breakage rate.
[0035] To ensure a simple, reliable, and easy-to-assemble structure, the preferred embodiment of this invention includes a sensor detection system comprising a multispectral sensor, a temperature sensor, a humidity sensor, and an audio sensor housed within a sealed belt conveyor. All sensors transmit received information to a control system, which in turn controls the conveying speed of the sealed belt conveyor. The multispectral sensor detects spectral information such as color and reflectivity of the rice husks during transport, identifying impurities, mold, or abnormal moisture content. The temperature and humidity sensors simultaneously monitor environmental parameters, detecting potential risks of localized overheating or dampness. The audio sensor captures collision and friction sounds during transport, quickly determining whether the rice husks are damaged or jammed through spectral analysis. When abnormal high-frequency noise is detected, the speed of the sealed belt conveyor is adjusted to reduce the likelihood of rice husk collision and damage. Through multi-dimensional, real-time monitoring and intelligent linkage, the sensor detection system proactively protects the integrity of the rice husks and ensures material quality during transport, while also optimizing equipment operation and maintenance.
