SU19622A1 - Method for neutralizing citric acid when fermented - Google Patents

Description

In the production of citric acid by fermentation, chalk or lime is usually consumed. On the other hand, one of the burdensome garbage produced in beet sugar is a filter press that contains, in addition to chalk and lime, a number of substances that can be used in those liquors. In order to replace chalk or lime with a filter press and reduce the cost

teia itself as a method of obtaining citric acid, and of freeing sugar factories from unnecessary ballast, in the proposed method, upon obtaining citric acid, fermentation as a neutralizing agent in the fermentation jug introduces filterstress from sugar factories. At the same time, when fermentation is carried out under sterile conditions, filter press is sterilized by conventional means also with formalin, either together with a fermenting solution, or separately.

The method of neutralizing citric acid acid is that, then sweet, the liquid obtained by dissolving chalk in water, or some other sugar worker, is infected with a culture of mold that produces citric acid (citiromyces aspergillus).

Flo the formation of acid or, at the very beginning of the process, is added to the mass of infected mold; filter press for neutralizing acid. If ferment. Conducted under sterile conditions, the filter press of the MOSCT should be sterilized. You can also put dirt into the solution of a sweet liquid and sterilize it. ..

In practice, the process of neutralizing citric acid can be carried out directly in sugar factories. For this, filter press is taken out of the plant - as thick as possible (in the form of filter press). The filter cakes are arranged in long, narrow rows, between the walls of the natural slope of which there are cavities where the sugary holds the liquid. On reaching temperature

indoors around 30 °, needed 1x for the flow of the Orogkeny, or the onset of the warm season (about 2. air in), muddy heaps filled with a chalky solution and contaminated with citrate-microbes. Fermentation continues throughout the warm season or when artificially heating the fermentation room throughout the year. Fermented solution time

© t is selected and filled with light. The assembled brew was brewed at the site of the same vacuum apparatus, and the obtained salt, or found in place, was transported to the corresponding plants for the production of pure acid. Similarly, filtrating grime should be applied to neutralize other types of acidic fermentation (for example, lactic acid fermentation).

For j-cnexa, the work of the phytopress 1n 1 can be sterilized by conventional methods of sterilization-boiling, for example, by applying aigaAHMa. salk,

1. A method for neutralizing LEMONIC acid in the preparation of fermentation thereof, characterized in that as a neutralizing substance, filter press is introduced into the fermentation liquid from sugar factories.

2. Acceptance of the method indicated in claim 1, characterized in that when administering fermentation under sterile conditions, filter press is sterilized by conventional methods using formalin or together with a brothyld solution, or separately before introduction into the latter.
