Abstract
The present disclosure relates to a mechanical frozen butter heater (40), a frozen butter reworking line (2) and a method of reworking frozen butter which are particular in being able to rework frozen butter without the butter having to be cut into chips prior to entry into the mechanical frozen butter heater (40), or the frozen butter reworking line (2) or used in the method of reworking frozen butter according to the invention.
Claims18
A frozen butter heater (40) comprising a mixer housing (43) comprising a cavity (45) arranged on a butter flow path between a housing entry (41) and a housing exit (42);
- where in said cavity (45) there is arranged an axle (50) across said butter flow path, said axle (50) comprising a plurality of cogwheels (51a, 51b, 51c, 51d) arranged co-axially with said axle between a set of butter seals (54a, 54b);
- said axle (50) rotably supported on bearings arranged in at least one bearings house (44a, 44b) arranged adjacent to said mixer housing (43), and operatively connected to a drive motor (52);
- wherein said drive motor (52) is arranged to maintain a rotational velocity of said axle (50) of between 1200 rpm to 2500 rpm against a flow of frozen butter.
A method of reworking blocks of frozen butter having a temperature between −25° C. to −15° C. in a frozen butter reworking line (2) defining a flow path for butter to obtain change-over to unfrozen butter comprising:
- providing blocks of frozen butter to an auger pump (10) to provide a flow of a mass of frozen butter to a butter pump (20);
- raising a pressure of said flow of a mass of frozen butter in said butter pump (20) to between 10 to 30 bar;
- supplying said flow of a mass of frozen butter to a sequence of at least three consecutively arranged frozen butter heaters (40a, 40b, 40c, 40d, 40e), each butter heater comprising an axle (50) arranged transversally to said flow path for butter and comprising a plurality of cogwheels (51a, 51b, 51c, 51d) arranged co-axially with said axle;
- rotating a said axle (50) on a respective frozen butter heater (40a, 40b, 40c, 40d, 40e) at between 1200 rpm to 2500 rpm to mechanically impact heat to said flow of a mass of frozen butter until a change-over to unfrozen butter is observed.
