[0034] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] Reference Figure 1-Figure 2 In an exemplary embodiment, a koji block fermentation system is provided, comprising:

[0036] Qufang 1;

[0037] A qu pile 2 placed in a qu room 1;

[0038] A detection device 3 for detecting the internal environment of the curved room 1;

[0039] A steam unit 7 for increasing the temperature of the koji room 1;

[0040] A humidifying unit 11 for humidifying the qu room 1;

[0041] A cooling unit for lowering the temperature of the curved room 1;

[0042] A circulating air unit for internally circulating the air in the curved room 1;

[0043] A ventilation unit for ventilating the flexure room 1; and

[0044] The intelligent control unit 14 is respectively connected to the detection device 3, the steam unit 7, the humidification unit 11, the cooling unit, the circulating air unit and the ventilation unit.

[0045] The system detects the internal environment of the koji room 1 (i.e., fermentation conditions) in real time through the detection device 3. When the internal environment of the koji room does not meet expectations, the intelligent control unit 14 is used to control and adjust. For example, when the temperature in the koji room 1 is too low, the steam unit 7 is controlled to increase the temperature; when the temperature in the koji room 1 is too high, the cooling unit is controlled to lower the temperature; when the humidity is low, the humidity is increased through the humidification unit 11; when the O2 content and CO2 content change, the ventilation unit is used to adjust. Thus, the whole process of koji fermentation is automated and intelligent.

[0046] Furthermore, the detection device 3 includes a temperature sensor, a humidity sensor, an O2 concentration detection sensor, and a CO2 concentration detection sensor, etc., wherein the temperature sensor and the humidity sensor can detect the temperature of the core of the koji, the temperature and humidity in the koji room 1, etc. The intelligent control unit 14 performs corresponding comparative analysis based on the detected data, and performs centralized control. For example, based on the detected temperature rise of the core of the koji and the internal temperature value of the koji room 1, the intelligent control unit 14 automatically controls the cooling unit after analysis to reduce the internal temperature of the koji room 1 and thus control the temperature rise state of the core of the koji. Based on the detected internal humidity of the koji room 1, the intelligent control unit 14 automatically controls the humidification unit 11 to adjust the internal humidity of the koji room 1 after comparing and analyzing the internal humidity value of the koji room 1 required for fermentation set by the system.

[0047] Furthermore, before the koji block enters the koji room 1, the intelligent control unit 14 automatically runs to analyze whether the requirements for entering the koji block are met according to the corresponding data obtained by the detection device 3 set in the koji room 1. If not, the steam unit 7 and the humidification unit 11 are started to humidify and heat the koji room accordingly, so that the internal environment of the koji room 1 meets the requirements for the entry of the koji block.

[0048] In one example, the steam unit 7 is arranged at the bottom of the qu room 1, and includes a steam boiler or other structure capable of generating steam. The cooling unit includes a valve 5, an axial flow fan 6 and a heat exchange plate 4 arranged in sequence, wherein the valve 5 is connected to the front end of a pipeline connected to the qu room 1, the rear end of the pipeline is connected to the axial flow fan 6, and the axial flow fan 6 is connected to the heat exchange plate 4. The circulating air unit includes a centrifugal fan 10, and an upper air outlet 8 and a lower air outlet 9 are arranged on the qu room 1, and the two ends of the centrifugal fan 10 are respectively connected to the upper air outlet 8 and the lower air outlet 9. The ventilation unit includes a ventilation outlet 12 and a fresh air outlet 13 arranged on the qu room.

[0049] In one example, detection devices 3 are respectively arranged on the upper and lower layers of the koji pile 2. Specifically, according to the number of layers of the koji pile 2, a lower layer detection device 3 is arranged on the lowest layer, and an upper layer detection device 3 is arranged on the highest layer. During the fermentation process, there will be a situation where the difference between the upper and lower layer detection data is too large. This situation is generally caused by the unevenness of the temperature field and the humidity field in the koji room 1.

[0050] In this regard, in order to ensure the uniformity of the temperature field and humidity field in the qu room 1, the centrifugal fan 10 needs to be started during the cooling and humidification process to circulate the air in the qu room to ensure the uniformity of temperature and humidity. Further explanation: the centrifugal fan 10 can be rotated forward and reversely. When rotating forward, the upper air outlet 8 is for outlet air, and the lower air outlet 9 is for suction air, so that the lower air of the qu room 1 is mixed with the upper air. When reversing, the lower outlet 9 is for outlet air, and the upper air outlet 8 is for suction air, so that the upper air of the qu room 1 is mixed with the lower air. The upper and lower differences can be eliminated by the circulating air unit to ensure that the temperature and humidity values ​​in the entire qu room 1 are balanced.

[0051] During the fermentation of the koji block, the temperature of the koji core and the koji room 1 continues to rise. In order to effectively suppress the fermentation temperature rise state, the intelligent control unit 14 compares the real-time data with the pre-set temperature rise curve according to the corresponding data obtained by the detection device 3. When the temperature of the koji room 1 is too high, the valve 5 is automatically opened, the axial flow fan 6 is started, and ventilation and cooling are carried out through the heat exchange plate 4. When the temperature of the koji room 1 or the koji core is too low, the steam unit 7 is started for heating.

[0052] During the fermentation of the koji block, as the koji block continues to ferment, the detection device 3 detects the O2 concentration and CO2 concentration in the koji room 1. At this time, the intelligent control unit 14 compares the detection data with the set value and controls the ventilation system according to the comparison. When the O2 concentration is too low and the CO2 concentration is too high, the ventilation port 12 is automatically opened, and the fresh air port 13 is opened to replace the indoor air by convection by introducing outdoor air, ensuring that the O2 concentration and CO2 concentration in the koji room 1 meet the requirements of the koji block fermentation.

[0053] In one example, the axial flow fan 6 has an air volume of 1000-8000m 3 The centrifugal fan 10 is selected to have an air volume of 6000-16000m 3 / h range of fans. The intelligent control unit 14 includes a PLC, and the PLC adopts a Siemens series controller. It should be noted that the models of various components including the axial flow fan 6, the centrifugal fan 10 and the PLC can be selected according to actual needs and are not interpreted as a limitation of the present application.

[0054] The above specific implementation methods are detailed descriptions of the present utility model. It cannot be determined that the specific implementation methods of the present utility model are limited to these descriptions. For ordinary technicians in the technical field to which the present utility model belongs, they can make several simple deductions and substitutions without departing from the concept of the present utility model, which should be regarded as belonging to the protection scope of the present utility model.
