Stirring and ventilation device for fermentation soft granule equipment

The stirring and ventilation device of the fermentation soft particle equipment should make the bubbles finely dispersed, fully mix the gas and liquid, ensure the necessary amount of dissolved oxygen in the fermentation liquid, improve the oxygen utilization rate, have enough cooling area to discharge the metabolic heat of microorganisms, and control different stages in the fermentation process. The required temperature, minimize dead angle, make cleaning and sterilization convenient, avoid staining and sealing, and minimize leakage. Self-priming fermenter The self-priming fermenter is a fermenter that self-priming air during the stirring process.

There is no need to configure air compressors or blowers, and it is widely used in the pharmaceutical industry, acetic acid industry, yeast industry and other industries. The non-stator rotary vane self-priming fermenter has a single-layer overflow jet reactor principle of the stator self-priming fermenter overflow jet self-priming fermenter: the projectile flow formed by the liquid overflow is used under the action of the liquid surface.

The jet self-priming fermentation tank of photosynthetic bacteria fermentation tank does not need to be equipped with air compressor or blower, and is widely used in pharmaceutical industry, acetic acid industry, yeast industry and other industries. Non-stator rotary vane self-priming fermenter with stator self-priming fermenter overflow jet self-priming fermenter jet self-priming fermenter flow, under the action of the liquid surface layer. The gas boundary layer near the surface of the liquid has a certain moving speed, thereby forming the flow and self-priming of the gas. Features: The structure is simple, the complicated air compressor and its auxiliary equipment are omitted, the power consumption is low, the productivity is large, the dissolved oxygen rate is high, and the effect of conveying the fermentation liquid is good.

The key to the photosynthetic fermenter equipment is the liquor brewing machinery with air circulation and mechanical equipment natural ventilation; liquid machinery equipment includes mechanical equipment hybrid, self-priming and natural ventilation hybrid. The principle of mechanical equipment mixing fermentation tank: the gas and the fermentation liquid are fully mixed with a mechanical stirrer to increase the dissolved oxygen concentration in the fermentation liquid. The reason for the increase of dissolved oxygen in the photosynthetic bacteria fermenter is that the gas enters the large bubble in the early stage and is crushed into small bubbles, which expands the total area of the vapor-liquid page and improves the volume dissolved oxygen index; after the bubbles are mixed and crushed, the upward adjustment rate decreases. Under the harm of the fluid produced by stirring, the bubbles change from parallel lines to curves. Due to the increase of the movement mode, the contact time of the vapor and liquid increases, which improves the utilization rate of oxygen in the gas. Under the action of the stirring device, the photosynthetic bacteria fermenter causes The obvious high liquid phase turbulence promotes the thinning and softening of the liquid film, and the expansion of the convective heat transfer index, thereby obtaining a larger volume dissolved oxygen index. The characteristics of mechanical equipment mixing fermenter The mixing effect of mechanical equipment can obtain a higher dissolved oxygen index, which is suitable for all kinds of fermentation.
