Legend 42 OP/AL System


Available as:

  • Single Legend 42
  • Twin In-line Legend 42
  • Double drop Legend 42

Application

For the automation of proofing and loading in the production of thin crust pizza. The OP/AL is composed of an Overhead Proofer (OP) and patented Automatic Loader (AL) plus one press.

The Twin In-line OP/AL is enhanced by the use of a second press in a tandem configuration.
