METHOD FOR MAKING BUTTER AND PERIODIC BUTTERMAKER FOR REALIZATION OF SAID METHOD Russian patent published in 1995 - IPC

FIELD: dairy industry. SUBSTANCE: entire cycle from loading of cream to unloading of butter is carried out in one stationary cylindrical container inclined to vertical. Pasteurization, cooling and holding of cooled cream for physical ripening take place with simultaneous mixing by a mixed reciprocating along the container axis. The cream is whipped by rotation of the same mixer, saturating said cream intensively with air due to movement of rotating mixer blades from the air into the cream mass, said movement caused by inclination of container to the vertical and eliminating stagnant zones due to reciprocating motion of the mixer. Then butter grain and buttermilk are separated by the divider moving from container bottom towards its cover and by the reciprocating motion of the mixer from the container cover to the divider. The butter grains are washed with simultaneous mixing by the mixer and butter is additionally pressed by the divider moving with closed holes towards the container cover. Moisture is dispersed in the divider by mashing of butter by the rotating mixer blades over the internal surface of the container cover. Ready butter is forced out of the container. The periodic buttermaker is made as a stationary cylindrical container whose axis is inclined to the vertical; the mixer accommodated in the container during all the processing stages except rotation about the container axis is capable of reciprocating along the same axis. The divider has closing holes and a rod which moves it along the container axis from the bottom to the cover which latter has an opening for loading of cream and discharge of ready butter. EFFECT: improved functional and operating characteristics. 2 cl, 7 dwg
