Due to the change of the bearing capacity and the height, physical and chemical indexes such as salt, water and the like can be changed due to the change of the height, and generally, if the stirring uniformity and timeliness are influenced, the sinking of salt, water and the like easily causes the phenomenon that materials are rotten and deteriorated due to too low local salt. Due to the change of the bearing capacity and the height, compared with the traditional fermentation vat or fermentation tank, the efficiency of ventilation and exhaust of unit specific surface area and sunlight irradiation is greatly different, which has great influence on the final fermentation end point of the product, the color of the formed product and the like. Therefore, the Pi county broad bean paste suitable for the semi-solid state fermentation state is not a physical position change for simply erecting a fermentation tank, and relates to the full mastery of related technologies such as the growth change rule of microorganisms, the realization of the solid-liquid-gas three-phase uniformity of materials, the timeliness of the removal of fermentation waste gas and heat exchange, the influence of a mechanical stirring mode on the damage of the materials, the positive promotion effect of the technical parameters of the stirring process on the growth of the microorganisms, the exchange of the fermentation waste gas and heat under the condition of no uncovering in rainy and snowy seasons and the like, and the key of the Pi county broad bean paste tank fermentation is how to further improve the automatic production level and the food safety protection level after the bearing capacity of a unit area is improved.
The fermentation tank for brewing the broad beans is more suitable for outdoor fermentation, high in automation degree and low in labor intensity, the broad beans are tedded and fermented slightly under the influence of the external environment, the occupied area is small, the bearing efficiency is high, and the material bearing capacity reaches 2.4t/m2(the bearing capacity of the fermentation vat and the fermentation tank is about 0.8-1t/m2) The bearing efficiency is obviously improved. Through the analysis of the height-diameter ratio matched with the materials of various fermentation tanks at present, the fermentation tank is suitable for the semi-solid fermentation materials with the height-diameter ratio of about 1.2-1.5, the comprehensive height-diameter ratio of the traditional fermentation tank is about 1.3, and the effective height-diameter ratio of the fermentation tank is 1.2 in consideration of the influence of overhigh height on stirring the materials and the like, so that the fermentation tank can be suitable for the semi-solid materials and is also suitable for the semi-solid materialsThe particularity of the materials is considered.
The embodiment of the application also provides a method for brewing and fermenting the Pixian bean paste, which is based on the bean paste brewing and fermenting tank of any one of the above embodiments and comprises the following steps:
discharging: putting the Pi county broad bean paste mixed clinker to be brewed and fermented into an outdoor fermentation tank;

Then, the brewed pi county bean cotyledon is subjected to physicochemical and sensory comparison with the traditional pi county bean cotyledon, and the comparison result is as follows:
Figure BDA0003220312670000122
for the brewing and fermenting method of the pi county broad bean paste in the embodiment of the application, it needs to be explained;
pi county broad bean paste has a large amount of mould, microzyme, bacteria and the like in the fermentation process, the water content is high in the early stage of fermentation, the dissolved oxygen is high, sweet paste is added to provide a large amount of carbon sources (glucose and the like) for microorganisms, and the microorganisms release a large amount of carbon dioxide and heat by utilizing the carbon sources through an EMP (glycolysis) path and a TCA (tricarboxylic acid cycle), so that sufficient oxygen is provided and the carbon dioxide is removed in an accelerated manner in the early stage of fermentation, the growth and the propagation of the microorganisms are facilitated, and the surface area of materials in a fermentation container is compared with the bearing weight data, and the fermentation cylinder and a fermentation tank are about 2.83m2T, fermentation tank 0.42m2The stirring times of the fermentation tank are about 7 times per day (1 time per day in the early stage of fermentation of the traditional Pixian bean paste, mainly for the reason of labor intensity, the actual increase times are beneficial to fermentation in the early stage), the influence of stirring on the material state and the promotion of enzymatic browning and non-enzymatic browning of the sweet paste on the formation of the special brown color of the Pixian bean paste is comprehensively considered, and the stirring times are set to be 4-5 hours once; the stirring time of a conventional fermentation cylinder/fermentation adjusting tank is approximately 0.3-0.5min/kg by manual or mechanical stirring, so the stirring time of the fermentation cylinder is 3-5 min/ton, and the fermentation time is 5-8 min due to the fact that the height of materials of the fermentation cylinder is approximately twice of that of the fermentation cylinder and the fermentation tank;
in the middle stage of fermentation, because the moisture of the materials is reduced, the dissolved oxygen is reduced, the carbon source is reduced, the growth and the reproduction of the microorganisms are slowed down, and the growth and the metabolism of the microorganisms in the secondary stage are relatively vigorous, but the secondary stage is not as early as the early stage of fermentation, the carbon dioxide and the heat generated by the metabolism are obviously reduced, and the secondary stage begins to enter the post-ripening and flavoring stage of the bean paste in Pi county, namely: lactic acid bacteria of bacteria produce lactic acid and ethanol generated by fermentation of yeast microorganisms, and the lactic acid and the ethanol form ester aroma-enhancing substances and the like, so that the stirring times of the fermentation tank and the stirring time of each stirring trend are reduced;
at the later stage of fermentation, because the water volatilization is obviously reduced, the viscosity of the material is obviously increased, the oxygen content of the material is obviously reduced, the growth of microorganisms is in an obvious logarithmic reduction stage, and the soybean paste enters an after-ripening and aroma-enhancing stage of a Pi county soybean paste, particularly a traditional Pi county soybean paste, the stage mainly takes standing fermentation as a main step, and the microorganisms secrete alcohols, aldehydes organic acids, esterification reaction thereof and the like generated by decomposing raw materials by various enzymes to form the peculiar taste of the Pi county soybean paste (because of the particularity of the semi-solid Pi county soybean paste fermentation materials, each fermentation period is not strictly distinguished, only the material fermentation process has certain correlation with the growth stage of the growth condition of the microorganisms, and is consistent with the traditional Pi county soybean paste fermentation mode, and each fermentation period in the physical meaning has the process of color enhancement and aroma enhancement. Traditional Pi county bean cotyledon adopts the pestle to stir, and the fermentation vat adopts single spiral leaf stirring (stirring rotational speed is more than 60 revolutions per minute), therefore, the damage degree to the material of comprehensive consideration, fermentation vat stirring spiral leaf rotational speed location 40-50 revolutions per minute can reduce spiral shearing effect.
Finally, it should be noted that: the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
