Definitions

  • the present invention relates to centrifugal wringers with continuous running constituted by a basket with vertical axis, in the form of an inverted truncated cone, equipped with a screen through which filters the liquid phase of the product to be wrung while the solid phase is expelled by the centrifugal force at the large diameter end of the basket and projected into a closed tank where the basket is housed.
  • nozzles or spray bars are used to project the mashing juice onto the crystals as they exit the basket and an annular collector onto which the mixture of crystals and juice is sprayed by centrifugal force .
  • These collectors which may have a circular, parabolic or frustoconical profile, are designed to retain a certain volume of this mixture and thus prevent the crystals from striking forcefully on the surface of the collector where they could break.
  • the centrifugal wringer object of the invention is characterized in that the collector consists of a flat ring, of small width, fixed internally on the wall of the tank, slightly below the horizontal plane resting on the upper edge of the basket, and in that it further comprises a circular skirt secured to the cover of the tank and placed above the upper edge of the basket with its lower edge located a short distance from the edge of the basket, and an annular trough for receiving the magma formed by the mixture of crystals and juice, the bottom of which is provided with several outlet orifices and has a downward slope when moving from one outlet orifice to the next in the direction of rotation of the basket.
  • the invention makes it possible to minimize the volume limited by the skirt, the cover of the tank, the wall of the tank, the internal wall and the bottom of the trough for receiving the magma and, consequently, to intensify in this volume the ventilation due to the rotation of the basket and the mixing of the magma that it causes.
  • the nozzles or ramps which direct the jets of juice onto the sheet of crystals expelled from the basket can be placed inside the basket, in the vicinity of the horizontal plane resting on the upper edge of the basket, the jets emitted by these nozzles or ramps being directed towards the edge of the basket.
  • the nozzles or ramps can be arranged around the skirt so that the paste juice is projected onto this skirt, flows to its lower edge and falls on the sheet of crystals expelled from the basket through the circular slot made between the lower edge of the skirt and the upper edge of the basket.
  • the wringer of the invention is equipped with an auxiliary watering ramp placed in the upper part of the tank, near its wall, and the jets of which are directed towards the ring and of a valve system enabling this ramp to be supplied with mashing juice as soon as the supply to the main sprinkler nozzles or ramps is cut and vice versa.
  • the wringer shown in Figure 1 comprises a tank 10 supporting the pivot 12 on which is rotatably mounted a basket 14 in the form of an inverted truncated cone equipped with a screen 16.
  • the product to be wrung is introduced by a pipe terie 18 in a distributor pot 20 fixed on the basket hub.
  • the purpose of this jar is to bring the product to be wrung to the bottom of the basket and to distribute it evenly over its entire periphery.
  • the product to be wrung which consists of a mass-cooked material, slides on the sieve 16 to the upper edge of the basket.
  • the liquid phase of the product to be filtered filters through the screen and flows through channels formed between the wall of the basket and the screen up to their upper end where there are openings opening into an annular chamber 22 surrounding the basket and delimited by circular partitions 24 and 26 and a bottom 28.
  • the solid particles of the product to be wrung which consist of sugar crystals, are expelled by centrifugal force when they reach the upper edge of the basket and are projected onto the wall of the tank.
  • the axial distance between the ring and the edge of the basket can vary but must always be small and will advantageously be less than 10 mm.
  • the magma constituting the sausage 38 is constantly renewed; after having stayed a certain time on the ring 36, it is discharged by gravity and collected in an annular trough 40 formed by the wall of the tank 10 and an extension of the circular partition 24.
  • the bottom of this trough has two orifices for outlet 42, diametrically opposite, and the bottom of the trough is formed by two portions of propeller or ring 44 inclined up and down, in the direction of rotation of the basket 14, the orifices 42 being located at both bottom points of the bottom ( Figures 2 and 3).
  • the gauge could comprise more than two outlet orifices which would in particular have the effect of increasing the slope of the bottom for the same height of the trough.
