Description

Plant full automatic microorganism fermenting case and using method thereof

Technical field

Patent of the present invention relates to a kind of microbial fermentation equipment and using method thereof, and specifically a kind of plant that is applicable to of two-way hot blast heating that adopts produces the new automatic microbial fermentation case of active microbiological preparations and the method that this fermenting case of use is produced active microbiological preparations.

Background technology

Living microorganism is more common in the market microbial preparation, and the common field of living microorganism comprises sewage disposal, food-processing, fermented feed, livestock and poultry cultivation, aquaculture, biological pesticide, biological organic fertilizer etc.Wherein, the probiotic bacterium that is applied to food and feedstuff industry is exactly a kind of by improving, balance host's intestinal flora, thus the host is played the living microorganism of beneficial effect.

Along with people are heightened to the demand of animal products, large-scale cultural technique has occupied main flow gradually.Carry out highdensity raising in the narrow space, air dirt in causing giving up, movement overflows, the temperature height, the humidity height causes animal easily sick, and the generation of pestilence is also more and more general.For a long time, people attempt in feed adding microbiotic or some chemical additives attempt to resist the pathogeny microorganism that influence growth of animals or poultry even cause livestock death, prevent pig, chicken sick.Antibiotic usage quantity and kind are more and more, and the resistance problem is more and more serious, and antibiotic remains is also more and more.In addition, along with increasing of feed additive matter, these materials can't be estimated the potential hazard that the mankind's healthy and ecotope causes.

19th-century sixties, once widelyd popularize fermented feed in China, the end of the seventies, the living microorganism cultural technique had to a certain degree influence to Chinese aquaculture so far.The common fermentation feed is a kind of natural fermented at random fully, be subjected to the variable effect of temperature, humidity, pH value easily, great variety also can take place in the microbe population and the kind of fermentation, the feed mouthfeel of producing, smell or color distortion are very big, and fermenting process also may produce toxic substance harm animal health.And the condition of organism of fermentation that fermentative feedstuff of microbe is used and fermentation all is controlled, therefore can produce steady quality, safe and reliable fermented feed.

The core theory of fermentative feedstuff of microbe cultural technique foundation is the intravital microecological balance of animal.The microecological balance of animal digestive tract has determined the healthy state of animal.Under the normal circumstances, the bacterium of enteron aisle (harmful bacterium, probiotics and neutral bacterium) keeps certain balance, keeps the function that normal enteron aisle is digested and assimilated.Owing to when a variety of causes causes the normal microflora of enteron aisle to change, just produce little disruption of ecological balance, and then cause various diseases.By the fermentative feedstuff of microbe of feeding, the probiotics in the feed can be regulated the bacterium colony balance of animal digestive tract, safeguards the normal micro-ecological environment of animal, improves immunizing power, thereby resists the generation of various diseases.Fermentative feedstuff of microbe has many-sided advantage: can produce low microbiotic even the residual animal products of antibiotic-free, ensure food safety, simultaneously ecotope is not damaged again, had increasing plant to begin to select fermentative feedstuff of microbe.

The range of application of living microorganism is very extensive, is most commonly used to fermented feed in plant, the prevention livestock and poultry, and water body health is kept in aquaculture, makes microbial pesticide, produces microbial organic fertilizer, produces aspects such as biogas.Living microorganism is the indispensable production means of modern agriculture.

Though fermentative feedstuff of microbe has many benefits, still there are some limiting factors to hamper the development of fermentative feedstuff of microbe.At present, there are three shortcomings in the production of fermentative feedstuff of microbe: the one, and the bacterial classification that the production fermented feed is used requires height to fermentation installation, invests too big.Carry out microbial fermentation and need comparatively strict aseptic condition, need special microbial fermentation equipment, sterilization and packaging facilities or the like, also to build high-level factory building, be equipped with the microbial fermentation operator through strict training, the very high bacterial classification price that causes fermented feed to be used of cost of investment is higher.The 2nd, produce the strain fermentation device structure complexity that fermented feed is used, the cost height.Present fermentation equipment mainly is a microorganism fermentation tank, generally includes water and air supply system, sterilising system, temperature controlling system, stirring system and delivery system etc., complex structure, Production Flow Chart complexity.In addition, production process needs High Temperature High Pressure and gnotobasis, so energy consumption cost is very high.General plant is difficult to possess working condition.The 3rd, the bacterial activity that is used for fermentative feedstuff of microbe is not high.Because the condition of microorganism existence is comparatively harsh, the improper forfeiture that all can cause microorganism active of temperature humidity.The probiotics of using mostly is pulvis now, and number of viable is limited, so result of use is had a greatly reduced quality.In addition, it is the process of a high energy consumption that active bacteria formulation is dried to the pulvis ability that is easy to transport and preserve by liquid state, adds transportation cost, so cost promotes significantly, and economic benefit is not high.

In fermentation process, one of of paramount importance technology is sterilization.The most frequently used sterilising method is the heat sterilization method in the microbial fermentation production, with boiling water, steam and steam pressurization sterilization.Steam pressurization sterilising effect is best, and available free flowing steam sterilization also can (generally use 1 kg/cm in the high compressed steam pot ²) sterilization, its vapour temperature can reach 121 ℃, heat-stable gemma all can be killed in 30 minutes.But to some easily by high pressure destructive material, as some sugar or nitrogen-containing organic compound, should be in 0.6 kg/cm ²(110 ℃) sterilization is 15～30 minutes under the pressure.The most frequently used in plant produced is free flowing steam sterilization, utilizes direct-fired circulation water vapour killing microorganisms.Pasteurization is dairy products enterprise a kind of sterilising method commonly used, comprise dual mode: 1. low temperature long time treatment: handled 30 minutes down at 61.7～65 ℃, adopt this method to handle milk, can kill various growth form pathogenic bacterium in the milk, sterilizing efficiency can reach 97.3%～99.9%, residual just part thermophile bacteria and thermotolerance bacterium and gemma etc. after sterilizing, but these bacterium majorities are milk-acid bacterias, and milk-acid bacteria is not only harmless good for health on the contrary to the people; 2. handle between high temperature, short time: at 71.6 ℃ or slightly handled 15 minutes under the high-temperature.Its sterilizing time is shorter, and working efficiency is higher.This method is usually used in the sterilization of dairy products, can preserve more nutritive substance.Because pasteurization only adopts lower temperature control just can finish sterilization process, and can preserve more nutritive substance, therefore, the equipment that adopts pasteurization to need is simple, can control automatically, production technique is grasped easily, and energy consumption is low, less investment is highly suitable in plant's microbial fermentation production material being sterilized.

The most frequently used ultra-violet sterilization is exactly by ultraviolet irradiation in the radiation sterilization, destroys and change DNA (thymus nucleic acid) structure of microorganism, makes the dead at once or irreproducible offspring of bacterium, reaches germ-resistant purpose.What really have germicidal action is that (wavelength 100～275nm is called shortwave sterilization ultraviolet ray again in the UVC ultraviolet ray.), absorbed by the DNA of organism because the C-band ultraviolet ray is very easy, best with the ultraviolet ray about 253.7nm especially.Ultra-violet sterilization belongs to pure physical disinfection method, has simple and convenient, broad-spectrum high efficacy, non-secondary pollution, is convenient to management and realizes advantages such as automatization.

In addition, adopt the fermenting case of hot blast heating relatively simple for structure in the market, defective the such as therefore heat that the electrothermal tubes that adopt the bottom the produce more natural convection heat supply that makes progress exists fermenting case internal temperature difference big, and temperature distributing disproportionation is even.Hindered the natural convection of hot blast when the more material of filling, therefore the situation of more having aggravated temperature distributing disproportionation can not satisfy in the real attenuation production the accurately requirement of control of temperature.
