Abstract
The invention relates to a method and an equipment for the preservation of vegetables, meat or other organic substances. The essential feature of the method proposed by the invention consists of placing the goods to be preserved into a hermetically sealed chamber (I, II), then varying the composition of the gases bound by the cell material of products. The essential feature of the equipment complying with the invention consists of placing the goods to be preserved into a hermetically sealed chamber (I, II), where the chamber (I, II) is connected with some means, advantageously with a gas pump, for varying the pressure within said chamber, or providing said chamber (I, II) with at least one hermetically sealed, movable wall for varying the volume of said chamber, further connecting the latter with a cooling circuit for providing the cooling of the chamber (I, II).
