Abstract: Prospects for the use of goat’s milk (GM) as a food system are associated with the intensification of biological processes of its reproduction, as well as technologies for its processing and preservation. The purpose of the study is to substantiate the method of preserving goat’s milk using an experimental spray freeze drying unit. The object of the study was the milk of goats of the Zaanen breed. The differential scanning calorimetry (DSC) method established a difference in the amount of binding energy of water fractions with dry matter in GM, which causes differences in energy consumption for GM dehydration at different stages of the drying process. The results were used to develop a drying method that makes it possible to carry out the processes of dehydration of goat lactation products under the gentlest conditions close to thermal conditions when producing these colloidal systems in the animal body. An experimental spray vacuum sublimation plant was used to produce granulated GM. Combining the structural elements of spray and freeze dryers allows balancing between the structural complexity of the device, its energy efficiency and the quality of the product.
