Juice extractor

An apparatus for extracting juice from raw juice containing material, said apparatus comprising:

• a housing for supporting said apparatus and including a raw juice containing material inlet;
• a pair of meshing helical gears (2,3) with each said helical gear terminating in a tapered screw, including a plurality of teeth each tooth of which is formed with an addendum and a dedendum which are equal to each other to enable zero clearance between meshing teeth, and being rotatably secured in said housing to enable in use raw juice containing material to be supplied through said inlet of said housing to said pair of meshing helical gears for crushing said raw juice containing material to initially extract juice therefrom;
• a sieve (4) operatively positioned around said helical gears and each said tapered screws for enabling in use filtering and draining away from said helical gears and said tapered screws juice extracted by said helical gears and said tapered screws and with said sieve being branched (47,48) each branch housing at least a portion of one of said tapered screws, respectively, and with each branch of said sieve having a terminal end with a discharge outlet formed thereat to enable each said screw to further extract juice from said crushed raw juice containing material by compressingly moving said crushed juice containing material along one of said branch portions of said sieve and toward one of said discharge outlets formed in said sieve, and
• a power means (1) for supplying rotational output to said helical gears and said tapered screws such that in use said raw material supplied through said inlet is moved along said helical gears to one of said tapered screws, along one of said tapered screws and through one of said outlets formed in said sieve.
