Title: Removable oven roasting insert - has air heated and driven around baffle plate around cooking food
Inventor: LUENEBURGER WALTER
IPC: F24C15/00

Accelerated crystal sepn. from a soln. esp. the removal of tartar as crystals from wine or other tartar-producing drinks. Rapid elimination of tartar in a continuous process which has no adverse effect on the flavour, appearance or other quality of a wine.
