Abstract

Apparatus for storing perishable animal and vegetable materials during a storage period, subject to changes due to respiratory deterioration when stored in air with normal amounts of oxygen and carbon dioxide, in which oxygen is consumed and carbon dioxide is produced in accordance with The following approximate equation of respiratory change: nO2 + (CH2O)n ------ nCO2 + nH2O wherein (CH2O) n represents a carbohydrate molecule derived from said materials, apparatus comprising: means constituting an enclosure with a storage space for said materials; a burner for burning carbonaceous fuel in the presence of air in quantities necessary to sustain the essentially complete combustion of said fuel and to give as combustion product an atmosphere containing oxygen and carbon dioxide; means associated with said burner to restrict the combustion temperature of said fuel to a level lower than the reaction temperature of oxygen with the nitrogen of said air preventing an important formation of nitrogen oxides, the amount of oxygen in said atmosphere being less than said normal amount of air to retard but not impede the course of said equation, and the amount of carbon dioxide in said atmosphere being greater than said normal amount of air to retard but not impede the course of said equation; means for circulating said atmosphere in said space during said period; and means for essentially continuously replenishing said atmosphere in said space.
