Description

TECHNICAL FIELD

[0001] The utility model relates to yellow wine brewing equipment technical field, especially in kind yellow wine wheat Qu solid culture positive pressure biological reaction system. BACKGROUND

[0002] Yellow wine as the representative of Chinese traditional brewing wine, its unique flavor formation highly depends on the quality of wheat Qu. The essence of wheat Qu solid culture process is to use the microbial community in the natural environment for directional propagation, and the traditional process adopts open culture room, and relies on natural ventilation and humidity change to complete microbial succession. However, this extensive production method has the following defects: first, uncontrollable environmental microorganisms are easy to cause bacterial pollution, resulting in rancidity or abnormal enzyme activity of finished product Qu; second, uneven distribution of temperature and humidity in the material pile causes local overheating or water loss, affecting the metabolic balance of microbial community; third, the culture process lacks real-time monitoring means, and the process adjustment seriously depends on experience judgment, which restricts the stability of product quality.

[0003] In recent years, some enterprises have tried to introduce biological reactor technology to improve the traditional process, but still face technical bottlenecks in practical application. The existing culture equipment mostly adopts single air filtration system, which can only intercept large particle pollutants, and the purification effect on volatile organic compounds and air-borne microorganisms is limited, and incomplete sterilization leads to a high bacterial contamination rate. In terms of positive pressure control, the traditional equipment generally uses constant speed fan combined with mechanical pressure relief valve, and the pressure regulation has hysteresis, which is difficult to maintain a stable micro-positive pressure environment, and external pollutants can easily penetrate through weak sealing points. The temperature and humidity control system mostly relies on external air conditioning equipment, which has slow response speed and high energy consumption, especially when the material pile height exceeds 1 meter, the temperature difference between the core and the surface of the pile can reach more than 8℃, which seriously affects the homogeneity of the microbial community.

[0004] The shortcomings of monitoring technology further amplify the above defects. Fixed sensors are usually arranged at the edge or top of the warehouse, which cannot adjust the monitoring points with the change of material form, resulting in the lack of key parameter collection in the pile body. The signal transmission system has weak anti-interference ability, and is easy to produce data drift under the conditions of high pressure sterilization, equipment start and stop, etc., which affects the decision accuracy of the control system. In addition, the existing equipment lacks modular design, and the filter replacement, probe maintenance and other operations need to be disassembled during shutdown, which seriously affects the continuous production capacity.

[0005] More serious is that the traditional technical route has inherent contradiction in energy efficiency and cost control. In order to maintain cleanliness, it is necessary to replace air at a high frequency, which brings huge energy consumption burden; and reducing the air exchange rate will lead to CO2 accumulation and inhibit microbial activity. This dilemma makes it difficult for existing equipment to be widely promoted in industrial production, and seriously restricts the modernization transformation of yellow wine industry. Therefore, developing a solid-state culture system which takes into account the environmental control accuracy, operation flexibility and energy consumption economy has become a technical problem to be solved in the field of brewing equipment.
