Malaxation method and device

摘要

Digesting a mash by malaxing, preferably an olive mash by a malaxing device, comprises: (a) producing heat conditions in at least one container (1); (b) moving the mash; (c) forming a continuous phase and/or an emulsion of water and oil from the released oil droplets; (d) performing optical recording of the mash surface; (e) comparing the successive images; (f) determining a portion of surface covered with oil in the mash by comparison; and (g) optionally determining an occurred variation of the portion of surface covered with oil depending on the malaxing time during comparison. Digesting a mash by malaxing, preferably an olive mash by a malaxing device, comprises: (a) producing heat conditions in at least one container (1), where the fruit enzymes and/or added enzymes softens the cell wall in the mash (2); (b) moving the mash so that the cells are lacerated; (c) forming a continuous phase and/or an emulsion of water and oil from the released oil droplets; (d) performing an optical recording of the mash surface repeatedly; (e) comparing the successive images; (f) determining a portion of surface covered with oil (AFS) in the mash by comparison; and (g) optionally determining an occurred variation of the portion of surface covered with oil depending on the malaxing time during the comparison. Independent claims are also included for a device for performing the above mentioned method, comprising at least one container with the heating element, a stirring device (6), at least one camera for recording the surface of the mash placed in malaxing container and at least one display or many displays for simultaneously displaying at least two recorded photos of at least a part of the mash surface, which are temporally and/or locally displaced from each other; and #a malaxing device for malaxing a mass, preferably a fruit mash comprising a container and an interfering agitator for stirring the mass, where the device comprises the agitator heat tracing element combined with the agitator, which is at least partially movable with the agitator.
