The invention relates to a method for preserving organic piece goods, for example, foods such as fruits, plants, parts thereof, small animals, and animal piece goods, and organic piece goods from the non-food sector, for example, cut flowers, using a dehydrating solvent and by drying in a drying device, and to a method for producing preserved organic piece goods. According to the invention, the organic piece goods are dried in the drying device in the presence of the solvent at temperatures below 100°C, preferably in a fluidized bed. Said procedure has the advantage of getting by with significantly lower drying temperatures compared to freeze drying, requiring substantially shorter drying times, and thus having significantly better energy efficiency, and being more environmentally friendly. A further important advantage is the gentle drying procedure, wherein the organic piece goods substantially retain the original shape, color, and contents thereof. |
