Rotary machine designed for the introduction of gas into the cans already containing products, dedicated specifically to the market for ready meals (obtained by mixing different bases of vegetables, tuna and sauces) to ensure optimum conservation by replacing air with an inert gas, and thus avoiding the use of preserving liquids such as oil, brine, sauces etc.

Most of the manufacturers of these ready meals use deep-drawn aluminum or tinplate cans, with easy peel lid to seam.

The most common formats are the single portion pack of 160 gr and 250 gr, both packed in clusters composed of two cans.

The can arriving from the telescopic filler are transferred to the filler. Here the oxygen contained into the cans is replaced with a mixture of nitrogen.

The process is carried out under high vacuum.

The cans are then transferred to the seamer in a tunnel pressurized and saturated with nitrogen.

All the process is controlled by gas analyzers that regulate the dosage of nitrogen based on the concentration detected.

Operating cycle

The cans are transferred by the inlet star on the lifting plates
The can is raised until the closure of the bell
The air in the can is sucked through the collector of the vacuum circuit
Injection of inert gas through the collector of the vacuum circuit
The can enters the tunnel that connects the filler to the seamer, and that is saturated with gas
The cans reaches the seamer where, before the operation of seaming, gas is injected betwee lid and can.

Products: ready meals, vegetables, legumes etc..
