The production cycle of complex processing of oilseeds with receiving vegetable oil, soluble and insoluble fraction from mix of the crushed pressing with heated water is offered; a squirrel from soluble fraction, the dried-up insoluble fraction. The main basic decision on decrease in energy consumption was the optimum choice of temperature differences in the evaporator and sections of the two-section condenser when receiving drying agents, the cooling air and warm water. The deviation from these values inevitably leads to increase in the consumed energy: fall of temperature of boiling of coolant in the evaporator on 1 °C results in need of increase in a consumption of working steam in the ejector of the paroezhektorny thermal pump, and therefore to an energy overexpenditure for 5–7 %, and temperature increase of condensation on 1° C leads to increase in power consumption by 2.0–2.5 %. The offered technology expands borders of energy efficient interface of objects of various temperature potentials on the basis of utilization and recovery of secondary energy resources. Universal approach in creation of the competitive technology providing heat generation and cold weather for in common proceeding heattechnological processes is fully realized. Ecologically safe conditions in implementation of technology due to use of water as coolant, excepting use toxic, vzryvo – and fire-dangerous working environments and also at the expense of the organization of the closed recirculation schemes for material and power streams with considerable decrease in removal of secondary energy resources from the scheme warm and cold supply are created.
