Description

The invention relates to the construction of a jet flotator for the flotation of proteins, for example in the production of protein-protein concentrate from green fame and forage.

Currently, the production of protein concentrate concentrate is most often solved by coagulation of proteins by steam heating of green squeezed fame from green fodder. The crystallized chloroplast and citoplasmic proteins are separated from the residual liquid by flotation in a flotation vessel, in a centrifuge or sludge press. These methods result in the loss of protein, since the citoplasmic protein forms a very, fine floccule, which remains in part in the residual liquid. In the flotation bath, due to the introduction of floccules, some of the citoplasmic proteins are separated, which then de-ooze in the residual liquid and imagine the losses. Using a centrifuge or sludge press, the coagulated fame either pumped directly to said devices, or is conveyed to a tank where mixing is performed so that the protein floccules are fine and the coagulated fame can be better pumped. Also in this case, the fine citoplastic proteins escape with the residual liquid.

The above-mentioned drawbacks are eliminated by the jet flotator according to the invention, serving for continuous flotation and agglomeration of solids floating in the liquid to be treated. It consists of a upright container with a supply of liquid to be passed through the bottom. According to the invention,

The upper part of the upright container is connected to the outlet trough by means of an outlet and is provided with an extended container, the lower part of which is provided with an emptying cut-out.

The container is preferably provided with a lid,

The jet flotator, downstream of the green fame steam coagulator, ensures the aggregation of the solid chloroplasmic proteins with the fine citoplamatic proteins. .This is created. protein clusters of several centimeters in size that rise upward and remain in the residual liquid · only a small proportion of the protein remains. Preferably, up to 50% of the residual liquid is drained through the screen at the bottom of the jet flotator. The floatation of the liquid with a low content of citoalasmatic proteins allows for a higher concentration. and reduces protein loss in the residual liquid in the following process.

An exemplary embodiment of the current flotator according to the invention is shown in longitudinal section in a drawing of the drawing,

air in case of screen cleaning In operation, the air is normally closed in the upper part of the vessel, a 12 "orifice through which the clusters of proteins together with a portion of the residual liquid through the trough 22 pass through to another device where large proteins are separated. residual liquid with minimal protein loss in residual liquid. A container 4 is formed around the top of the vessel / jet flotator, which, in order to increase the flow of coagulate into the jet flotator, catches the overflow around the entire upper edge of the vessel / and gradually discharges through the discharge slot 21. The upper sr is closed

The jet flotator preferably provides pre-treatment of the green state in the production of the protein concentrate. The juice in which, for example, proteins, which are in the form of fine floccules, have been coagulated by heating, is fed to a jet flotator. By slowly rising the coagulate, secured by the upright vessel of the flotator, the aggregation of fine floccules of protein occurs, so that in the upper part it forms a continuous cake which tears at the overflow edge. Protein clumps of several centimeters are carried out by a portion of the residual liquid through a trough for further processing. A portion of the residual pure liquid of 30-50% is drained at the bottom of the jet flotator. Partial sieve clogging may occur after several hours of operation. By squeezing the compressed air for a few seconds, the sieve is cleaned and continuous cake formation continues.
