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.
