Description

Sposób niniejisizy poleiga na odcukrza- niu melasy dowolna metoda i odfermento¬ waniu otrzymanych roztworów cukrowych zapomoca drozdzy w obecnosci alkalizato- rów, jak weglanu amonowego i innych.Poboczne produkty jak alkohol lub kwas octowy moga byc uzyte do odcdkrzania.Z otrzymanej brzeczki wydziela sie przez odwirowanie drozdze, wyosabnia uzyta do alkalizacji substancje, zuzywajac w tym celu kwas weglowy, otrzymany z fermentacji i oddestylowuje alkohol oraz aldehyd. Po oddestylowaniu alkoholu, al¬ kaliczny wywar zageszcza sie do 30°Be, zadaje kwasem siarkowym do reakcji kwasnej i dalej zageszcza do 40°Be. Przy powtórnem zagesizczeniu w srodowisku kwasnem oddestylowuje sie z para wodna kwas octowy, który pochlania roztwór wapna lub sody. Po zageszczeniu plynu, takowy poddaje sie destylacji w prózni z przegrzana para dla odpedzenia glice¬ ryny.Roztwór niecukrów melasowych, za¬ wierajacy cala ilosc azotu i potasu, a otrzymany po odcukrzeniu melasy zage¬ szcza sie na stacji wyparnej i miesza otrzy¬ many kleisty plyn z drobno sproszkowa¬ nym wysuszonym torfem, przyczem masa cala sie zestala. Mase stala miele sie na proszek i stosuje jako nawóz azotowo-po- tasowy. PL PLThe process of this process is performed on the suction of molasses by any method and the fermentation of the obtained sugar solutions by means of yeast in the presence of alkalizers such as ammonium carbonate and others. By-products such as alcohol or acetic acid can be used for de-icing. centrifugation of the yeast isolates the substances used for alkalization, using carbonic acid obtained from fermentation, and distills the alcohol and aldehyde. After the alcohol has been distilled off, the alkaline stillage is concentrated to 30 ° Be, mixed with sulfuric acid for an acid reaction and further concentrated to 40 ° Be. When it is concentrated again in an acidic environment, the acetic acid distills off from the steam, which absorbs the lime or soda solution. After the liquid is concentrated, it is distilled in a vacuum with superheated steam to strip off the glycerin. A molasses solution containing all the nitrogen and potassium, and the resulting molasses decalcification is concentrated in the evaporation station and the result is sticky. the fluid with finely powdered dried peat, while the mass solidified. The solid mass is ground into a powder and used as a nitrogen-potassium fertilizer. PL PL

Claims

1. Patent claims. 1. The method of obtaining glycerin, acetic acid and potassium-nitrogen fertilizers from molasses, characterized by the fact that ammonium carbonate and other alkali that can be regenerated by treatment with carbonic acid are used as an alkalizing agent for fermentation, obtained by fermenting sugar by yeast,

2. The method according to claim 1, characterized by the recovery of all the ingredients, fermented in a alkaline environment, molasses and the use of a common system of concentration of decoction decoctions, glycerin fermentation liquors and acetic salts, with steam from the last section of the evaporation station for the concentration of the broths will be used to concentrate the wort. glycerin, and the concentration and crystallization of acetic salts. 3. The method according to claims 1 and 2, characterized by the use of pulverized peat to obtain a solid fertilizer from a liquid and sticky molasses decoction. Tadeusz Sliwinski. Deputy: Inz. J.
