Abstract From the Canadian patent

A molder/chiller for pasta filata cheeses uses segmented water jackets each holding a plurality of mold tubes. The jackets may be separately filled with chilled water for chilling and heated water for releasing the cheese blocks as a wheel rotates made up of the jackets rotates. A central water distribution valve and manifold with radiating source and sink pipes allows simple closed loop cooling and heating fluid circulation reducing contamination and providing improved energy efficiency and elimination of the need for Teflon coatings. Rotation of the distribution manifold may provide the needed valving action without separate controllers.

Why it's free to use

  • Filed October 8, 1998 and granted October 23, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 8, 2018.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 8, 2020.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
