Abstract
Fermentation cylinder is used in natto production relates to natto production equipment, the dedicated fermentation cylinder structure of concretely relates to natto production. Including the fermentation cylinder body, the (mixing) shaft is installed to the center in the fermentation cylinder body, installs stirring vane on the (mixing) shaft, the bottom center is fixed with the base of ventilating in the fermentation cylinder body, and upper and lower butt joint constitutes the upper seat body that the base of ventilating was appeared by two round platforms with lower pedestal, have the annular recess of circle respectively on upper seat body and the lower pedestal butt joint face, two groove phases are provided with an intake pipe that feeds through with annular gas circuit to forming annular gas circuit in the hole of lower pedestal, and intake -tube connection sets up in the vent line of fermentation cylinder body outside, at the equidistant fumarole that is provided with of upper seat body's toper periphery, the annular gas circuit of fumarole intercommunication. The utility model provides an among the present natto fermentation process raw materials too sticky, dispersion that gas that present fermentation cylinder let in can not be even leads to the fact the problem that ferment effect is not good.
Description
Technical field
The utility model relates to the natto plant-scale equipment, is specifically related to natto and produces gas-supplying structure in special fermentor tank.
Background technology
The production technique of natto: the process of (1) raw material--removing foreign matter, the ordered raw soybeans come from various places harvest of particle shape, work selected once again; (2) beans, dipping is washed--as far as possible at low temperatures; (3) boiling--according to soybean varieties, particle shape, changes pressure and time; (4) Bacillus natto is inoculated; The temperature of soybean is preferably between 90 ~ 70 DEG C; (5) filling engineering is put--mechanical filling and hand packing; (6) introducing operation, is pendulum individual layer in large container in principle; (7) fermentation engineering--main points are temperature and temperature treatment, comprising: 1. give cold (inductive phase) according to fermentation size and introduction volume number, precooling operation is different.Outside summer during temperature height, be first transferred to room temperature 30 DEG C of precoolings 1 hour, be transferred to germination the bread worm more afterwards, Bacillus natto must have moisture to work as medium to absorb nutrient, therefore, to the incomplete veneer case container of leak tightness, must increase humidity in inductive phase; 2. to germinate breeding (inductive phase); 3. (logarithmic phase) is fermented; 4. cooling (dying the phase) is forced in maturation; (8) refrigerate maturation--must below 5 DEG C low temperature.
In natto production, crucial operation is fermentation, a large amount of heat of fermentation can be produced when Bacillus natto breeding arrives logarithmic phase during the fermentation, on average approximately just produced large calorimetric through 8 hours, namely raw soybeans temperature starts to rise, 50 DEG C can be broken through, the special small seed soybean that surface-area is larger or grind the rising of the very fast performance such as soybean temperature to 12 hours its temperature.In this stage because oxygen demand is large, with to gas, gas barrier, one side provides air, and one side discharges fermentating metabolism gas and aqueous vapor
Existing fermentor tank is generally used for fermentable, and its main body is generally to be made with stainless steel plate.Its volume at 1 cubic metre to hundreds of cubic meter.In designing and processing, claimed structure is tightly reasonable, can tolerate steam sterilizing, have certain turndown ratio, and contents reduces as far as possible, avoid dead angle material, transmission ofenergy performance is strong, and can necessarily regulate, so that cleaning, decreasing pollution, is suitable for the production of multiple product and reduces energy expenditure.
The whipping appts of existing fermentor tank is installed on the top of tank, and for ceaselessly stirring in the middle of fermenting process, the pipeline passing into the auxiliary material (as pH value regulates raw material or trace element etc.) required for fermentation is arranged at bottom.Because soybean isoflavone by natto strain Raw is too sticky, the gas that existing fermentor tank passes into can not disperse uniformly, causes ferment effect bad.
Summary of the invention
The utility model provides natto production fermentor tank, and the utility model solves that existing soybean isoflavone by natto strain Raw is too sticky, and the gas that existing fermentor tank passes into can not disperse uniformly, causes the problem that ferment effect is bad.
For solving the problem, the utility model adopts following technical scheme: natto production fermentor tank, comprises fermentor tank body, and in fermentor tank body, central position is provided with stir shaft, and stir shaft is provided with agitating vane; Be fixed with ventilation pedestal at fermentor tank body inner bottom part center, ventilation pedestal is docked up and down by the upper pedestal of two truncated cone-shaped and lower base and forms; Upper pedestal and lower base binding surface have respectively the groove of annular, two grooves form annular gas channel relatively, and be provided with an inlet pipe be communicated with annular gas channel in the hole of lower base, inlet pipe is connected in the vent line of fermentor tank body exterior; Be provided with gas orifice the tapered circumferential surface of upper pedestal is equally spaced, gas orifice is communicated with annular gas channel.
The utility model is equipped with the gas orifice surrounding annular in fermentor tank body inner bottom part interposition, gas orifice is positioned at immediately below agitating vane, agitating vane carries out stirring while, gas orifice upwards sprays oxygen or air, make air feed even, gas can be in the feed dispersed to greatest extent, and then improve ferment effect.Gas orifice is arranged on conical surface, gas oblique upper ejection towards periphery, makes each position of periphery all can insufflation gas, realizes the plenum system without dead angle.
