Abstract: The plant for cold pressing for olive flesh after previous removal of olive kernel, has a core removing machine that includes electric motor that works with a mechanism for three speeds, a pressurized water, a sieve and circularly running shovel. The core removing machine during the separation of the kernel and the olive flesh fills a cylindrical, double walled container with olive flesh and oil must at the same time, over which during the filling a plate loading machine is found that lets down a circular, perfectly fitting plate into the container till the container is completely filled. The plant for cold pressing for olive flesh after previous removal of olive kernel, has a core-removing machine that includes electric motor that works with a mechanism for three speeds, pressurized water and a sieve. The machine during the separation of the kernel and the olive flesh fills a cylindrical, double walled container with olive flesh and oil must at the same time, over which during the filling a plate loading machine is found, which according to weight of the mass of a determined filling quantity automatically at intervals lets down a circular, perfectly fitting plate into the container till the container is completely filled. The container is present on a pressing station with a conveyer belt. The container is shuffled on the place of the press centrifuge by the succeeding container and is hydraulically lowered on to the floor of the press centrifuge by a rail mechanism. Before and during the compressing and centrifugation, valves of the container are opened and the fluid (oil must) that is collected between the outer and inner wall of the container is let into a canal system, is caught by a container and then directed to a separating filter. The pressed olive mass is transported to the plate. The machine after taking the olives in the olive basket with an olive flush outlet (6) that is opened and closed according to size and quantity of the olives through a rotation of its spindles with the knives beats the olives, to separate the kernel and the olive flesh. The flesh falls on a sieve centrifuge (7), through a suction propeller (11) under the sieve to the horizontally turning grinding stones (10) sucks with the centrifugal force and pulverizes and then conveys to the olive-flesh outlet. The nozzles are fed through the water feeding line into the machine and moisten the walls and the knives from time to time. The cylindrical loading machine with its guiding rod is formed telescope like. On the floor of the press centrifuge, two parallel female indentations are present, and in the floor of the these indentations two rails are elevated, whose upper part is feminine, so that the male rails fit under the floor of the container and are hydraulically elevated or brought down, so that if the container is positioned itself in the middle of the press centrifuge, the hoisting device automatically hydraulically sinks down, so that the rails of the container sits exactly in the middle of the press centrifuge. The floor of the press centrifuge has a circumferentially running collecting duct for the oil must, in which the confluence of the four discharges of the container gushes out during the opening of the valves. The press centrifuge in its middle has a pressing rod and in its deepest place, a circular press punch, which is constructed in such a manner, that it does not allow any fluid to climb upwards. The floor plate of the press-centrifuge with the outer- and inner wall and the floor of the container during the compressing and the centrifugation are firmly closed. The floor-plate of the container, before leaving of the press floor, is closed again, outer and inner walls are erected and the firmly pressed material on the plates on the container floor are removed, by two forks of a forklift mechanism. The machine works on many divided levels of spindle with knives, with a blade wall cleaner (4), which collects the chipped material from the upper level and forwards it down into the middle of the funnel like opening to the next level, and with two exhaust fans, which transport the olive flesh under the sieve to two outlets right and left, under the grinding stone. The machine sucks the olive flesh with the movable grinding stone by centrifugal force and then grinds it, and fills the ground olive flesh after outlet with a pout in the funnel like widening of the inner upper boundary of the container. The machine in canal for the kernel for the outlet of the kernel has semi-circular uprisings in the sieve for removing the rest of the olive flesh. The machine before the kernel outlet has a circularly running shovel, which is connected to the exhaust fan. The machine in the canal has the sieve for the kernel for the olive flesh still fallen away from the kernel, from where it is collected by a scrapper and transported down through ventilators to the remaining olive flesh. The machine has two grinding zones. The lower grinding stone is faster than the upper grinding stone. The container is found between an inner circle and an outer circle of the pressing station. The machine is located in the middle of the inner circle and turns on its axes to the nearest container. Each container is equipped on its floor interior with a circular sheet without a hole in the middle, so that the first portion of the filling product is assimilated during the filling. Each container has two male rails and four effluences in its floor for the discharge of fluid from the hollow space. The floor of the base has a hollow canal and outer double circular indentations, which fit into the inner wall and are protected by gaskets against the fluid discharge. On the base of the press centrifugal floor, four pillars of the press centrifuge are anchored, on which the cover of the total press-installation sits, which holds the container in the centrifuge and the press-centrifuge stable. The container holder holds the container in its position, so that it turns along, when the centrifuge is in motion.
