Abstract
The invention discloses a process water sterilization system for fermentation, and belongs to the technical field of sterilization. The system comprises a metering tank, a hypochlorous acid storage tank, a process water storage tank, an ultraviolet sterilization device, a mixing tank, a middle storage tank and a preheating tank, wherein the process water storage tank, the ultraviolet sterilization device, the mixing tank, the middle storage tank and the preheating tank are sequentially connected through a pipe. The segment, between the ultraviolet sterilization device and the mixing tank, of the pipe is provided with a flowmeter. The middle storage tank is provided with an exhaust opening with a bacterium filtering screen, and the hypochlorous acid storage tank, the metering tank and the mixing tank are sequentially connected through a pipe. According to the process water sterilization system, process water is sterilized by virtue of the sterilization function of the ultraviolet sterilization device, and the adding amount of hypochlorous acid is reduced accordingly; according to the specific scheme, the ultraviolet sterilization device is arranged on a water outlet pipe of a process water pipe to sterilize the process water, the content of the hypochlorous acid in the process water used in a plant is lowered greatly, normal growth of yeast cells is guaranteed to the maximum degree, and meanwhile residuals of hypochlorite are reduced.
Description
Technical field
The present invention relates to sterilization technology field, particularly one fermentation process water disinfection system.
Background technology
The main raw material of yeast industry is the waste molasses produced after the sugaring of sugar refinery, comprises cane molasses and beet sirup.Molasses carry out fermentative production yeast after treatment, after being separated, washing, obtain yeast finished product after drying.Process water refer to be used in the industrial production manufacturing, converted products and with manufacture, relevant this part of machining process use water.In the industrial production of yeast and yeast extract, can need a large amount of process waters, because yeast and yeast extract are food use, therefore process water needs sterilization, usually can add a large amount of drift ices in water.
Yeast and yeast extract are all used to cook food, in process water, a large amount of interpolation during drift ice can directly cause fermentation and extract to be produced remains drift ice, the residual meeting of drift ice has certain infringement to human body, we know simultaneously, the main component of drift ice is chlorine bleach liquor, and hypochlorite remaining in tank can produce certain influence to saccharomycetic growth simultaneously.
Summary of the invention
In order to reduce, drift ice is residual to be impacted saccharomycetic growth, the invention provides a kind of fermentation process water disinfection system, this system is by the germicidal action of ultraviolet sterilizer, to process water through row sterilization, thus reduce the interpolation of drift ice, concrete scheme installs ultraviolet sterilizer at the outlet conduit of technique water pipe, to process water through row sterilization, thus the content of drift ice in process water is reduced greatly, farthest ensure that the normal growth of yeast cell, decrease the residual of hypochlorite simultaneously.Described technical scheme is as follows:
The invention provides a kind of fermentation process water disinfection system, this system comprises test tank, drift ice storage tank and the process water storage tank, ultraviolet sterilization apparatus, mixing tank, relay tank and the preheating can that are connected successively by pipeline, pipeline between described ultraviolet sterilization apparatus and mixing tank is provided with under meter, described relay tank is provided with the venting port of band bacteriological filtration net, and described drift ice storage tank, test tank are connected by pipeline successively with mixing tank.
Further, this fermentation process water disinfection system also comprises drift ice electrolysis generating apparatus and blend tank, described drift ice electrolysis generating apparatus, blend tank are connected by pipeline successively with drift ice storage tank, and the water outlet of described ultraviolet sterilization apparatus is connected with the water supplement port of blend tank by pipeline.
Wherein, the relay tank in the embodiment of the present invention is provided with stirring and light-passing board.
The beneficial effect of the fermentation process water disinfection system that the embodiment of the present invention provides is:
1, the sterilization of ultraviolet to bacterium, virus uses the general sterilizing rate that can reach 99%-99.9% to two second, and sterilization speed is fast; The broad spectrum of ultra-violet sterilization is the highest, and it can high-level efficiency be killed nearly all bacterium, virus; Ultra-violet sterilization does not add any chemical agent, and therefore it can not produce secondary pollution to water body and surrounding environment, does not change any composition in water; Ultra-violet sterilization equipment takes up an area little, and structures require simple, and therefore gross investment is less.
2, this system is by relay tank and preheating can respectively by leaving standstill and heat effect, and decomposed clorox, reduces and impact saccharomycetic growth.
3, this system requirements strictly controls the usage quantity of drift ice, reduces the use of clorox, and then, reduce and saccharomycetic growth is impacted.
4, this system obtain drift ice by drift ice electrolysis generating apparatus and and process water be mixed to get fresh drift ice, ensure the sterilization effect of drift ice, and then reduce the use of drift ice.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
