  • said membrane (IMM) has an outer surface comprising a plurality of preferably elastic protrusions and/or elastic pads 655 (lb) designed to create a plurality of contact's surfaces with the surfaces of the dishes placed in the basket (3B) said elastic pads which facilitate the outflow and propagation of the treatment fluids essentially during the steps in wich the blocking system is activated, according to the present invention.
  • IMM also has a plurality of openings associated with a plurality of nozzles (U10) positioned adequately between said elastic pads (lb), said nozzles (U10) for spraying the treatment fluids in the direction of the dishes 6B) through the jets (G5) suitably positioned in the spaces between said elastic pads (lb). It is important to specify that said elastic pads having the main function of spacing the surface of the elastic membrane (IMM) from the surface of the dishes
  • the said elasticity of the pads depending on the elastic properties of the material associated with said pads (lb) being said pads which can be joined to the same membrane material (IMM) or associable, said pads (lb) to different materials, said materials having greater or less elasticity depending on the characteristics of the treatment, the type of dishes, the types of fluids used.
  • the membrane (IMM) can be connected with the treatment fluids
  • the said membrane (IMM) can spray the treatment fluids through the nozzles (U10) with the jets (G5), creating, in conjunction with the jets from the sprayers (Rl), (R2), (R3), some particularly effective and concentrated treatment's fluxes within the reduced volume of the secondary wash chamber (26S) Fig. 7, said secondary chamber partially delimited by the membrane
  • said membrane (IMM) may also have the sole function of spraying the treatment fluids at adjustable distances from the dishes, said conformation being suitably controllable also
  • the blocking action of the dishes according to this preferred embodiment is carried out according to the same steps as described in the preceding embodiment.
  • the blocking action of the dishes is basically performed by the contact of the elastic pads (lb) uniformly distributed on the outer membrane surface (IMM) in conjunction
