Abstract: FIELD: agriculture. 
     SUBSTANCE: method for producing fodder briquettes and line for their production are proposed. The method for producing fodder briquettes involves obtaining the homogeneous mixture of components, then cooling the resulting mixture and forming the briquettes. First, the crushed wheat grain is mixed with water at the ratio of 1:3, the resulting mixture is preheated to the temperature of 40…50°C, then the gelatinization of the grain suspension is carried out at the temperature of 75…80°C, and its dextrinization with the introduction of the α-amylase enzyme is carried out at the temperature of 65…70°C. The resulting grain molasses are mixed with hydrol, bentonite, sunflower oilcake, tricalcium phosphate, calcium oxide and a premix at the temperature of 110…115°C until the degree of uniformity is equal to 95…97%. The resulting mass is dosed, moulded, cooled with air to the temperature of 20…25°C and output as a finished product. All components are taken at a specified ratio. The line for the production of fodder briquettes provides for the preparation of energy carriers to perform the technological operations with using a heat pump contains the sites of: preparing the grain syrup; dosing-mixing the components; moulding and cooling the briquettes; preparing the energy carriers for the implementation of the technological operations. The site of preparing grain syrup includes a recuperator-heat exchanger, a gelatination apparatus for grain starch with a heating jacket and a stirrer, a dextrinization apparatus with a cooling jacket, a condensate collector, dosing pumps. The site of dosing-mixing the components includes hoppers above the dosing devices, equipped with feeders, a reactor-mixer with a heating jacket and a stirrer. The site of moulding and cooling the briquettes includes a dispenser-discharger, a convection cooling chamber with a fan. The site of preparing energy carriers includes a steam generator with a coil oil heater and a safety valve, a high-temperature oil pump and a high-temperature heat pump consisting of a compressor, a condenser, a two-section evaporator, a thermoregulating valve, operating in the closed thermodynamic cycle. Wherein in the condenser of the high-temperature heat pump at the refrigerant condensation temperature of 150…160°C by means of recuperative heat transfer, the thermal oil is heated to the temperature of 130…140°C and by means of the high-temperature oil pump is directed to the coil of the oil heater of the steam generator to obtain heating steam with the temperature of 120…130°C, one part of which is fed to the heating jacket of the gelatination apparatus, and the other - to the heating jacket of the reactor-mixer, and the resulting condensate streams are combined and transferred to the condensate collector, with the subsequent feeding to the heat exchanger-recuperator to preheat the grain suspension to the temperature of 40-50°C, and returned to the steam generator to form a recirculation loop. The boiling point of the refrigerant in the evaporator sections is adjusted as -5… -10°C, and by means of recuperative heat exchange in the first section of the evaporator of the high-temperature heat pump, the air is cooled to the temperature of 15…18°C and fed to the chamber for the convective cooling of the briquettes, with the return to the first evaporator section in a closed loop, and in the second evaporator section the water is cooled to the temperature of 15…18°C and directed to the cooling jacket of the dextrinization apparatus, with the return of the waste water to the second evaporator section to form a recirculation loop. 
     EFFECT: expansion of assortment of high-quality fodder briquettes; reducing the heat energy costs per mass unit of the product; Increasing the ecological safety of the line for producing fodder briquettes as a system of technological processes.
