Abstract
Abstract A process for preparing precooked lasagna in which the ingredients are mixed and then extruded to form at least two uncooked strips of pasta. After passing the strips through the cooker, they are deposited into a cooling tank where they are allowed to accumulate. A separator and guide means aligns the noodles on top of one another as they pass out of the cooling tank. The noodles are then passed above and below the nozzle where a filler material is deposited between the strips. The strips are then cut for packaging.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
138 words
A continuous asynchronous process for making precooked lasagna comprising the following sequential steps: extruding at least two continuous strips of uncooked broad lasagna type noodles onto a conveyor; cooking the strips as they are being continually passed through a cooking means; collecting the noodle strips in a cooling tank; drawing the strips from the cooling tank while leaving a predetermined amount of noodles in the tank to provide slack for asynchronous operation of the process; separating the continuous strips from each other as they are drawn from the tank; aligning one of the strips on top of the other strip in a horizontal orientation; passing the top strip over and the bottom strip under a nozzle; feeding a substance through the nozzle, thereby creating a filling between the strips; and cutting the strips into lengths of predetermined size.
