METHOD FOR REMOVING WASTE PRODUCTS OBTAINED BY A PROCESS FOR EXTRACTING JUICE, OR PUREE, FROM VEGETABLE OR ANIMAL FOOD, AND APPARATUS THEREFOR

摘要

An apparatus for removal of waste material in a process for extracting puree, or juice, from a starting product based on vegetable or animal food including a step of feeding a measured amount of starting product to a machine for extracting puree. The starting product can be pre-treated, for example softened, and then subject to an extraction step, obtaining a main product including the puree, which is discharged via a first outlet, and a waste material that is discharged via a second outlet. The waste material is then mixed with a measured amount of a liquid, for example water, obtaining a heterogeneous mixture. The heterogeneous mixture can be thus easily removed by suction, for example by a hydraulic pump connected to the second outlet, to be quickly withdrawn from the extraction section avoiding the risk of jamming the machine at the second outlet.

主权项

1. An apparatus for removal of waste material in a process for extracting puree, or juice, from vegetable or animal food, said apparatus comprising:
a feeding section for feeding the vegetable or animal food to an extraction section of an extraction machine arranged to extract a main product comprising said puree, or juice; wherein the extraction section comprises: a rotor that works in combination with a sieve that has a plurality of holes, in order to provide a separation of said food into the main product that passes through the holes of the sieve pushed by the rotor and into a substantially solid waste material that does not pass through the holes of the sieve; a first outlet arranged in the lower portion of the extraction machine for discharging the main product that has passed through said holes; a second outlet arranged in the lower portion of the extraction machine and downstream of the first outlet for discharging the substantially solid waste material that has not passed through said holes; an adding section for adding a measured amount of a liquid to said substantially solid waste material, the adding section arranged downstream of said extraction section, and at said second outlet in order to obtain a heterogeneous mixture comprising said waste material and said liquid; and a suction section for removing said heterogeneous mixture from said second outlet; wherein the suction section comprises a suction pump in communication with the second outlet and arranged to create a vacuum environment in the extraction section for minimizing the enzymatic reactions.
