A kind of multifunctional bio solid-state fermentation tank
Affiliated technical field
The present invention relates to the biological fermentation field of machining and machinebuilding technology, a kind of biosolids fermentor tank, especially a kind of multifunctional bio solid-state fermentation tank.
Background technology
Solid fermentation is risen in China, has long history in several thousand.Solid fermentation can be used for producing biological fodder, bio-feritlizer, and biological pesticide, zymin, organic acid, numerous products such as functional food have the production efficiency height, and facility investment is few, advantages such as environmentally safe.Solid fermentation is made up of water-insoluble solid, a spot of moisture and air, fermenting process production by biological thermal conductance causes moisture evaporation, make fermentation system have the solid inhomogeneous three-phase of vapour-liquid, there are serious concentration gradient and heat transfer, mass transfer difficulty, be difficult to control pH, moisture, leavening temperature etc. like this, fermentation yield is descended greatly.Fairly large solid fermentation device mainly contains shallow tray fermentation at present, thick-layer ventilating fermentation pond, disc type solid fermentation, vertical tapered solid fermentor tank etc.But shallow tray fermentation exists the amount of labour used big, the easy microbiological contamination of inoculation culture link, can't large-scale production etc. shortcoming; Thick-layer ventilating fermentation pond exists the charging discharging can't automatization, and inoculation and the easy microbiological contamination of fermenting process such as can't mix at shortcoming; The disc type solid fermentation exists coefficient low, mix inhomogeneous, inoculation difficulty, shortcoming such as discharging is unclean has only single fermentation function, can't realize functions such as sterilization, vacuum dehydrating at lower temperature; Vertical tapered solid fermentor tank mixing of materials is inhomogeneous, and energy consumption is big, inoculation difficulty, and no functions/drying can't uniform mixing to material in the fermenting process, non-uniform temperature.Therefore there are many shortcomings in existing solid fermentation apparatus, and the production application of solid fermentation is almost stayed cool, and can't realize the suitability for industrialized production of solid fermentation.
Summary of the invention
Low in order to overcome existing disc type solid fermentation coefficient, mix inhomogeneous, inoculation difficulty, discharging is unclean, can't realize functions such as sterilization, vacuum dehydrating at lower temperature; Inhomogeneous in order to overcome vertical tapered solid fermentor tank mixing of materials, energy consumption is big, inoculation difficulty, and no functions/drying can't uniform mixing to material in the fermenting process, the uneven temperature deficiency.The invention provides a kind of multifunctional bio solid-state fermentation tank, the functions such as required sterilization, cooling, liquid inoculation, temperature control, fermentation, control are wet, ventilation, vacuum drying of can fermenting to solid materials are finished in solid-state fermentation tank simultaneously.And by horizontal spiral oar and tank body below auger coupled system in unique tank body, solid materials is formed in tank body to circulate, the low thorough mixing of shearing, avoiding using repeatedly motor just changeing the inhomogeneous or material of stirring that counter-rotating causes at one end ties extremely, and can realize self-emptying, and discharging is totally complete.
The technical solution adopted for the present invention to solve the technical problems is: the fermentor tank agent structure is the horizontal spiral blade, has installed screw auger and has advanced the blade sheet side under jar, material stainless steel or carbon steel, chuck and vent-pipe insulation cooling, tank body internal screw blade is that forward and reverse are one when work, square screw auger advances the blade sheet that material is advanced to equilibrium in the other direction under jar, open the discharge port door during discharging, start a jar beneath square screw auger and advance the blade self-emptying, no ramming material in jar, it is convenient to clean, temperature automatically controlled, automatically control pH, ventilate, automatic stepless speed-regulating control screw blade and screw auger advance blade sheet rotating speed, adopt bottom sterile air shunt conduit to ventilate, to adopt the multiple logical oxygen mode of different controls to different material and different nutrient solutions, can adopt the air-flow pulse mode to make a jar interior material roll temperature in the controlling tank up and down, moisture content and amount of oxygen, revolving oar by spiral rotates, about when material is moved in jar, about roll and make material in jar, not change dead and be bonded together, make material distributed equalization in jar.
The present invention adopts the sterile air shunt conduit under jar bottom auger to ventilate and switches to steam, make a jar interior material high-temperature sterilization, reach aseptic requirement, the logical sterile air of vent-pipe under logical water coolant of chuck and jar bottom auger cools off fast, adopt tank body top injection spray pipe to insert liquid seeds, adopt interior horizontal spiral oar of tank body and jar beneath side opposite direction screw auger, make material uniform mixing in jar, adopt bottom sterile air pipeline or adopt the air-flow pulse mode that a jar interior material is rolled up and down, temperature and air flow in the controlling tank, because fermentation is carried out in airtight solid-state fermentation tank, realized pollution-free fermentation, after the fermentation ends, interlayer is heated, with water spraying pulling vacuum concentrate drying, make and reach desired moisture in the material, start a jar beneath square screw auger and advance the blade self-emptying, fermenting process does not have waste water, waste discharge, realized that zero pollutes, so multifunctional bio solid-state fermentation tank of the present invention, can finish the required sterilization of solid materials fermentation, cooling, liquid inoculation, temperature control, fermentation, control is wet, ventilation, operating process such as vacuum drying, and owing to adopt chuck cooling and vent-pipe or two kinds of temperature control methods of pulse ventilation, the burning Qu Wenti that has avoided the too high generation bulk fermentation of material thickness heat to cause, therefore biosolids fermentor tank volume of the present invention and coefficient all improve a lot, and can realize commercial scale production.
The present invention adopts horizontal spiral oar and tank body below auger coupled system in unique tank body, solid materials is formed in tank body circulate, and thorough mixing avoids using repeatedly motor just changeing the stirring ununiformity that counter-rotating causes; The directly logical down steam sterilizing of square flood dragon under the jar, blowing air cools off, aerobic fermentation; Adopt tank body top that a plurality of atomizers spray inoculations are arranged, the damping of also can spraying water realizes evenly inoculation and controlling moisture; Can carry out the low-shearing power thorough mixing to material during the fermentation, but and self-emptying.
Beneficial effect of the present invention is: the solid fermentation all operations all can be finished in multifunctional bio solid-state fermentation tank of the present invention, thoroughly solved conventional solid fermentation equipment function singleness, easily microbiological contamination, labor capacity is big, coefficient is low, difficult problems such as uncontrollable mixing stirring, temperature, humidity have realized commercial scale production, have reduced production cost and facility investment.
