Perfected machine for preparing a portion of fried food and for immediately distributing of this portion

A machine for preparing a portion of fried food and immediately distributing this portion, comprising a housing;

• a deep-pan for containing a mixture of oils supported within said housing;
• a heat source connected to said deep-pan for keeping said oil mixture at a preset temperature;
• a delivery station positioned within said housing;
• a pivotable mesh drainer having a net-part and a solid part, said drainer, being rotatable about a horizontal axis from a filling position, in which said net-part is immersed in said mixture, in said deep-pan, to an emptying position, in which said solid part of said drainer, shaped in such a way as to convey fried food, is rotated to a positioned over said delivering station;
• said housing defining a doorway making said delivering station accessible from outside said housing
• a magazine for raw food;
• means for delivering a preset portion of raw food from said raw food magazine;
• guiding means positioned within said housing to receive raw food from said delivering means and raw food magazine and to convey said preset raw food portion to said deep-pan;
• a container feeder for a pile of containers located over said delivering station, said feeder having means to part a container lowest in said pile and to drop the parted container into said delivering station;
• a purifier for eliminating greasy fumes from said heated oil mixture;
• means interconnecting said deep-pan and said purifier for conveying greasy fumes coming out from said heated oil mixture to said purifier;
• said purifier having means to eliminate said greasy fumes;
• said means comprising a first aspirating means connected thereto;
• an electric-electronic control unit for controlling said heat source, the rotational movement of said drainer, said delivering means, said container feeder, said means for conveying said greasy fumes to said purifier, and said purifier;
• said purifier comprising:
• a first countercurrent heat exchanger having a core with an electrical heating element to receive a first air flow containing said greasy fumes through said conveying means as a result of a preset depression caused by said aspirating means,
• a second heat exchanger connected in series with said first exchanger for partially condensing steam generated during food frying present in said first air flow after said first flow has passed through said first heat exchanger;
• a cap attached to said first heat exchanger defining a hollow space communicating with an exit of said second heat exchanger, and in which said first heat exchanger is located and having first and second openings to the outside;
• a second aspirating means connected to said cap for sending a second air flow coming from outside into said hollow space, through said first opening, in order to cool the outer surface of said first exchanger and to create a third air flow by mixing said second flow coming from the outside, with said first air flow coming from said second heat exchanger;
• said second openings discharging said third air flow to the outside.

• guiding means positioned within said housing to receive raw food from said delivering means and raw food magazine and convey said preset raw food portion to said deep-pan;
• a container feeder located over said delivering station and supplied with a pile of containers, said feeder having means to part a lowermost container from said pile and dropping the parted container into said delivering station;
• a purifier for eliminating greasy fumes from said heated oil mixture;
• means for conveying greasy fumes coming out from said heated oil mixture to said purifier;
• an electric-electronic control unit for controlling said heat source, the rotational movement of said drainer, said delivering means, said container feeder, said means for conveying said greasy fumes to said purifier, and said purifier;
• said container feeder means comprising;
• a fixed rectangular frame with two control arms respectively fixed to two opposite transverse sides of said frame;
• brackets respectively fastened to opposed free ends of said control arms for positioning and laterally containing said pile;
• first means for adjusting the distance between said brackets and for adjusting the position of said brackets in respect of the longitudinal axis of said frame;
• a trolley having two longitudinal sheets received in support and guided by longitudinal bars forming said frame;
• second means controlled by said control unit and designed for longitudinally moving said trolley according to a forward stroke and a return stroke;
• two plates fitted to said related sheets and designed to receive in support corresponding parts of the border of a lowermost container of said pile when said trolley is placed in an idle position;
• two longitudinal bands fastened to said trolley, each band following a related plate, with respect to said forward stroke of said trolley, and being at an upper level in respect of said related plate in order to receive in support a corresponding portion of the border of the penultimate container of said pile just before the disengagement of said lowermost container from said sheets;
• two elastic strips centrally joined to said trolley and having related rear ends fastened to said trolley with an end segment of each strip extending towards a corresponding plate and located downstream of said corresponding plate, in respect of said forward stroke of said trolley, said end segment being positioned beneath, and resiliently kept in contact with, a corresponding band as a result of the articulated joint connecting a central segment of said strip to said trolley;
• fixed stopping means designed to be struck by a rear segment of said strip, as a consequence of said forward stroke of said trolley and after said plates have disengaged from related portions of the border of said lowermost container of said pile, said end segments of said strips turning downwardly and parting said lowermost container from said pile.
