Description

Baker's yeast fermentation catalytic device Technical Field The invention relates to the field of bread fermentation, in particular to a baker's yeast fermentation catalytic device. Background The quality and flavor of the bread serving as a main flow flour food depend on the accurate control of the yeast fermentation process, the temperature field stability of the yeast fermentation, the pressure equalization in a cavity and the metabolic acidity control are core factors for determining the success or failure of fermentation, and the performance of the fermentation box serving as a core carrier for bread yeast fermentation directly determines the quality and yield of bread production. The existing commercial and household bread fermenting box is mainly provided with a closed cavity structure matched with a top single-point pressure relief mechanism, so that the problem of emission of interference gas at the top of the cavity can be solved, the physical characteristic that CO 2 density is larger than that of air is ignored, natural sinking trend exists in CO 2 generated during fermentation, CO 2 generated by a bread embryo bottom contact surface is blocked by self weight of dough and a bearing structure and cannot escape upwards in time, the existing equipment has no bottom gas dredging structure, the partial accumulation of CO 2 at the bottom of the cavity is extremely easy to cause, high-concentration CO 2 can inhibit normal aerobic metabolism of yeast, and the problems of uneven fermentation, collapse at the bottom of the dough, rapid increase of acid yield and the like are directly caused. Meanwhile, the temperature control system of the existing fermentation tank adopts a side wall or top heating mode, the temperature difference between the upper and lower cavities is easy to form, the temperature fluctuation of the bottom temperature zone is large, a stable proper temperature field cannot be provided for yeast fermentation, the retention and accumulation of bottom CO 2 are aggravated, and the disorder of yeast metabolism rhythm is easily caused. The fermentation equipment with water circulation heat preservation is partially adopted, and a sufficient amount of heat source is needed to preserve the heat of the water body during the water body circulation, so that the heat loss of the water body is large, the temperature control response is delayed, and the problem of detention of bottom CO 2 cannot be solved by single water body circulation, so that the cooperative adaptation of temperature control and gas dredging is difficult to realize. In addition, the synchronous prevention and control of acidity in the fermentation process can not be realized by the conventional fermentation equipment, excessive fermentation can be avoided only through long control during fermentation, but the problem of accumulation of trace acidic substances generated in the normal metabolism process of yeast can not be solved, a neutralization mechanism aiming at acidic gaseous substances at the bottom is avoided, the long-term accumulation of the acidic substances can not only lead to the flavor sourness and quality reduction of bread finished products, but also corrode the internal components of the equipment, the service life of the equipment is shortened, and the large-scale and standardized production requirements of high-quality bread are difficult to meet, so that the bread yeast fermentation catalytic equipment is necessary to be designed.
