Abstract
The invention discloses a vinegar culture preparation method which comprises the following steps: (1) arranging seed culture used in a culture preparation procedure in the traditional edible vinegar solid-state fermentation process in the head end of a fermentation tank; (2) spreading a fresh material on the culture material, wherein the thickness is 20-30% of the height of the tank; (3) after the spreading of the fresh material, overturning the material, and simultaneously moving the material to the tail end of the tank, wherein the moving distance is 1/8-1/20 of the length of the tank, the height of the material after culture overturning is the height prior to the spreading of the fresh material, and the length is increased by 1/8-1/20 of the length of the tank; (4) after culture overturning, spreading brans or rice hulls having a thickness of 2-5cm on the material, or covering a straw mulch on the material; and (5) repeating the steps (2)-(4) at a certain time interval, and starting to discharge when the material in the fermentation tank exceeds the tail end of the tank. The invention is an edible vinegar semi-continuous solid-state fermentation process, the fresh material is added into the vinegar culture capable of realizing stable fermentation, and the process is simple. By adopting the invention, the seed quality is stable, the vinegar culture fermentation is stable, the fermentation efficiency is high, and the labor intensity of moving out the vinegar culture can be lowered.
Description
Technical field
The present invention relates to vinegar unstrained spirits zymotechnique in a kind of vinegar production process, specifically a kind of vinegar unstrained spirits making method.
Background technology
In existing vinegar solid-state fermentation process such as zhenjiang vinegar, Shanxi mature vinegar or other solid state fermentation vinegar production processes material after treatment (like modes such as immersion, boiling, zymamsis or pulverizing, enzyme processing) place fermentation vat or cylinder; Inoculation seed unstrained spirits or other form fermented bacteriums; (as 2-3 days) are turned over unstrained spirits or layering by certain frequency (as once a day) and are turned over unstrained spirits (after unstrained spirits is turned in layering for several times, turning over to the bottom) behind the same day or the certain hour then; Because material and fermentation mode is different; The sky was short to less than 10 days surplus fermentation time grew to 20, and this fermenting process seals unstrained spirits or the ageing of vinegar unstrained spirits after finishing.
The shortcoming of prior art is: the quality of seed unstrained spirits is unstable; Inoculation seed unstrained spirits or bacterial classification, microbes biomass increases gradually, so prior fermentation efficient is low and each batch vinegar unstrained spirits fermentation appearance unstable; The i.e. enlarged culturing progressively of unstrained spirits is turned in layering, and partial material is not inoculated, and fermentation efficiency is low; Fermentation ends or ageing are taken out the vinegar unstrained spirits after finishing from fermentation vat or cylinder, labour intensity is high.
Summary of the invention
In order to overcome the deficiency of prior art, the object of the present invention is to provide a kind of fermentation stability, fermentation efficiency height and vinegar unstrained spirits to shift out the low vinegar unstrained spirits making method of labour intensity.
In order to solve above-mentioned purpose, the technical scheme that the present invention adopted is: a kind of vinegar unstrained spirits making method, this method comprises the steps:
1) beginning to place the seed unstrained spirits that traditional vinegar solid-state fermentation process system unstrained spirits link is used from the fermenter head end, highly is the high 60-70% of groove, and length is the 40-50% (tail end has natural grade) of flute length;
2) virgin material is laid on the above-mentioned unstrained spirits material, thickness is the high 20-40% of groove, and wants evenly;
3) spread virgin material after, promptly to turn material and realize that simultaneously material moves to the tail end of groove with the turnover plate type turning-over device, miles of relative movement is the 1/8-1/20 of flute length, turn over height of materials behind the unstrained spirits for the shop virgin material before height and length increase the 1/8-1/20 of flute length;
4) turn over behind the unstrained spirits thick chaff or the rice husk of 2-5cm, or cover covering materials such as straw mulch on the material upper berth;
5) repeat above-mentioned steps 2 at interval by certain hour) to step 4), the tail end that the material in fermenter is crossed groove promptly begins discharging, so far promptly forms semicontinuous slot type solid state fermentation.
In the step 3), said miles of relative movement was decided by the system unstrained spirits cycle, and the system unstrained spirits cycle is different different because of raw material, technology, weather etc., and for grog system unstrained spirits, fermentation period is 8-10 days, and miles of relative movement is the 1/8-1/10 of flute length; For raw material system unstrained spirits, fermentation period is 15-20 days, and miles of relative movement is the 1/15-1/20 of flute length.
Fermentation period refers to unstrained spirits material constancy of volume in the hypothesis fermenting process among the present invention, and unstrained spirits material TV and charging every day is equivalent to the fate that ferments in the fermenter than promptly.Grog system unstrained spirits is Shanxi vinegar or similar technology, and raw material system unstrained spirits is brown vinegar or similar technology.
In the step 5), said certain hour is spaced apart 0.5-1 days.
In the step 5), said load by volume is calculated, and its length is the miles of relative movement of material when turning over unstrained spirits, highly is that fermenter height, width are the fermenter width.
Among the present invention; In the groove volume of material and cell body amass be a fixed value as 0.9 o'clock, the height and the fermentation period of said fermenter are proportionate, the fermenter height is between 1.0m-1.5m the time; The corresponding grog system unstrained spirits cycle is 8-10 days, and the corresponding raw material system unstrained spirits cycle is 15-20 days; The length of fermenter causes the displacement of material to turn in the cycle with a system unstrained spirits that the unstrained spirits number of times is to be amassed for turn over unstrained spirits at every turn, and fermenter length should not be less than 10m, otherwise the turning-over device utilization ratio is low excessively; Fermenter length and timing highly, its width is decided by required single load, and the fermenter width is slightly less than the turning-over device width simultaneously.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is a kind of vinegar semi continuous solid-state fermentation process, by adding virgin material in the vinegar unstrained spirits that changes fermentation stability to material inoculation seed unstrained spirits or bacterial classification into; Technology is simple, adopt the present invention after, seed quality is stable, vinegar unstrained spirits fermentation stability, fermentation efficiency are high, and can also reduce the vinegar unstrained spirits and shift out labour intensity.
