Definitions

Furthermore, with seeds of small grain size, blockages of the oil outlet openings may occur.
  • a screw press (screw press) is known, which is equipped with a strainer basket. This is formed of a plurality of rods which are arranged in a region for the oil outlet parallel to each other around the screw. Between two adjacent bars a gap is formed, through which the oil emerges.

The gap is variable and must be adapted to the oilseed. Depending on the seed length, different gaps must be used across the length of the seed basket, so that preparation for operation requires sufficient time and experience.

  • the majority of the slots are always free for the oil, while the solids are retained according to the width of the slot.
  • the stepwise changed widths of the slots on the one hand support the clogging-free operation.
  • the outer surface of the housing is substantially increased, so that heat generated by the pressing can be better dissipated.
  • the oil obtained with the screw press according to the invention therefore has up to 10 times lower temperatures than other known presses. The oil is thus thermally stressed and has a better quality.

A in the direction of rotation of the screw 2 rear leg of the triangle is parallel to the longitudinal axis of the housing part 1 b. A cross-section of the recesses 10 is also triangular, with their depth increases steadily in the direction of rotation of the screw 2 and in addition with the transport direction.

  • the outlet opening 8 is formed in a replaceable nozzle body 9 so that its cross-section initially decreases in the transport direction to a predetermined value, in order then to become larger again after a short distance.
  • the screw 2 is driven so that oily pressed material to be filled into the hopper 5 is transported in the casing 1 from the filling port 4 to the discharge port. Since the discharge of the pressed material is obstructed by constriction in the accumulating head 7, a pressure increasing in the direction of transport in the pressed material builds up in the screw extruder, especially in the region of the depressions 10; At the same time, the recesses 10 cause shearing forces in the material to be pressed. As a result, the existing in the pressed material liquid, which consists at least predominantly of oil, pressed out of the solid and with a small amount of debris, ie fine solid particles, through the Slots 6 pushed out of the screw press and collected. In this case, the oil flows against the transport direction in the gap, which is formed by the play between the housing 1 and the screw 2, to the slots 6. The majority of the solid remains up to the outlet opening 8 in the screw press.
  • the solid of the pressed material is strongly compressed in the accumulating head 7 and emerges from the outlet opening 8 as a solid strand, which is largely smooth on the outside, and can be divided into pellets. He has a low residual content of oil.
  • the recovered oil is optionally further removed with a filter of solids.

Abstract

L'invention concerne une extrudeuse destinée à fabriquer des huiles, comprenant un boîtier (1) pourvu d'une section transversale cylindrique circulaire. Une ouverture de remplissage (4) est ménagée dans la zone d'une première extrémité du boîtier (1), une ouverture de sortie (8) pour la matière solide est ménagée sur une deuxième extrémité du boîtier (1), et des ouvertures de sortie d'huile sont ménagées dans une zone prédéterminée (B) entre l'ouverture de remplissage (4) et l'ouverture de sortie (8). L'ouverture de sortie (8) est ménagée dans une bague collectrice (7). L'extrudeuse comprend également une vis sans fin (2) destinée à transporter et à presser la matière à presser et montée de manière à pouvoir tourner dans le boîtier (1). L'invention vise à améliorer l'extrudeuse de manière à ce que ses ouvertures de sortie d'huile aient moins tendance à être obstruées, y compris lorsque la matière à broyer présente des grains fins. A cet effet, les ouvertures de sortie d'huile sont réalisées sous la forme de fentes (6), qui s'étendent parallèlement à un axe longitudinal du boîtier (1) et présentent, vu de l'intérieur vers l'extérieur, une section transversale à largeurs variables de manière échelonnée, la plus petite des largeurs étant associée à une face intérieure du boîtier (1).
