obtained from the absorption step can simply be spread onto a support made of wire mesh and allowed to air dry the drying time in this air drying step is dependent upon the material being dried and the time allotted to the absorption step it is usually possible to complete the entire process all three steps in 24 hours or less at the end of that period a stable product dry to the touch is obtained whose appearance flavor and aroma are closer to those of the fresh food than is the case with other conventionally dehydrated products in order that those skilled in the art can more fully understand the present invention the following examples are set forth these examples are given solely for purposes of illustration and should not be considered as expressing limitations unless so set forth in the appended claims all parts and percentages are by weight unless otherwise stated one hundred and twenty eight grams of ground fresh spinach were loaded into a nylon mesh sack and placed between a perforated static piston and a solid moving piston in a food press both pistons and all the other parts of the food press were made of stainless steel external pressure 8 000 10 000 psi was then applied to the system through a hydraulic jack the jack was mounted on metal frames so that it would remain immobile during the pressing stage the activated.
