ABSTRACT:
Apparatus capable of operating both as nitrogen generator and carbon dioxide absorber, particularly for the preservation under controlled atmosphere of fruit and vegetable products, comprising a generator in turn including a burner, having a mixture of air and fuel gas supplied thereto, and in which a combustion is effected, so that a mixture exits from the generator as comprising steam, nitrogen and carbon dioxide, two absorbers each of which for retaining carbon dioxide, connection means between the generator and absorbers, comprising a condenser, for the removal of the steam, so as to supply to either absorber only a mixture of nitrogen and carbon dioxide, means for feeding the gas exiting from either absorber to the cell or storage room containing the products, or alternatively to the outlet, means for connecting the cell with either absorber for supplying the cell atmosphere thereto, means by which when one of the abosrbers is operating to retain carbon dioxide of the gaseous mass from the burner or cell, the other absorber is passed through by scavenging air and vice versa, means for operating the apparatus only as nitrogen generator or only as carbon dioxide absorber of the cell atmosphere, means for water cooling said condenser and burner, comprising two opposite walls of the burner, each of which includes a gas passed through by the cooling water, and in the gaps means for distributing the water circulating in the gaps, so as to cause a substantially even distribution of the temperature.
