Embodiment 1

[0024] As shown in Figure 1, a special reactor 3 in the preparation method of liquid vinegar is installed at the bottom of 100 liters of fermentor 1, and the chassis 6 of reactor 3 matches with fermentor 1 bottom shape, drops into fermentor 1 After fermenting the mash 2, feed the compressed air of 0.3 MPa into the reactor 3 through the air inlet pipe 5, the volume ratio of feeding the compressed air and the fermenting mash is 1:0.08, and the air passes through the microporous tube of the reactor 3 4 evenly escapes and infiltrates into the fermented mash 2, fully atomizes the gas and liquid in the fermented mash 2, improves the oxygen transfer coefficient to the acetic acid bacteria, increases the amount of dissolved oxygen, and satisfies the aerobic microorganisms to the greatest extent. The needs of the growth, reproduction and metabolism of acetic acid bacteria continue to ferment the mash 2 maturation after 28 hours to obtain liquid vinegar.

Embodiment 2

[0027] Same as Example 1, the difference is that a special reactor 3 in the preparation method of a liquid vinegar is installed at the bottom of the 3 cubic meter fermenter 1, and the chassis 6 of the reactor 3 matches the shape of the bottom of the fermenter 1, to After dropping into the fermented mash 2 in the fermenter 1, feed the compressed air of 0.2 MPa into the reactor 3 through the air inlet pipe 5, the volume ratio of the compressed air and the fermented mash is 1:0.1, and the air from the reactor The microporous tube 4 of 3 evenly escapes and infiltrates into the fermented mash 2, so that the gas and liquid in the fermented mash 2 are fully atomized, improve the oxygen transfer coefficient to the acetic acid bacteria, increase the amount of dissolved oxygen, and maximize the Satisfy the needs of the growth, reproduction and metabolism of the aerobic microorganism acetic acid bacteria, and mature after 29 hours to obtain liquid vinegar.

Abstract

The present invention relates to a preparation method of liquid edible vinegar and its special-purpose reactor. Said preparation method includes the following steps: adding fermenting mash liquor into a fermentation cylinder, introducing air into a reactor positioned in the bottom portion of said fermentation cylinder, making the air be uniformly escaped from said reactor and penetrated into fermenting mash liquor to make the gas and liquid in fermenting mash liquor be fully atomized continuously for 25-30 hr so as to obtain liquid edible vinegar. Said invention also provides the concrete structure of its special-purpose reactor.

Description

(1) Technical field [0001] The invention relates to a production process of liquid vinegar, in particular to a preparation method of liquid vinegar and a special reactor. (2) Background technology [0002] At present, liquid fermented vinegar is mainly produced by processes such as liquid pouring, static fermentation, and self-priming submerged fermentation. The liquid pouring process requires frequent replacement of fillers, which is too troublesome; the production cycle of the static fermentation process is too long; therefore, at present, many enterprises adopt the self-priming deep fermentation process, but the one-time investment of the self-priming deep fermentation process equipment is relatively low. Many, high power consumption. The self-priming submerged fermentation process is to inhale air through self-priming, drive the rotor to rotate through the rotation of the motor, stir the fermented mash, and the agitated fermented mash contacts the air to absorb oxygen. ...
