Description

The utility model relates to the food industry, namely to the technology for the production of fats from raw materials of animal origin.

A known line for the extraction of fat from raw materials of animal origin in horizontal vacuum boilers, which consists of a device for feeding raw materials in buckets, scales for weighing raw materials, a crusher for grinding bones, a drum for washing raw materials, flushing fat in horizontal vacuum boilers, draining machines for separating fat from greaves, draining greaves, a sump for receiving fat, a pump for pumping grease, draining grease into a container, a cooling drum for cooling grease, a pressure tank for filling, receiving chilled grease into a boiler with a mesh alcohol, filling apparatus for filling fat into small containers, draining fat into barrels, receiving fat into a collector, filtering fat on a filter press, squeezing fat from a press, receiving pulp from a press, creating a vacuum by a vacuum pump, crushers to grind pulley, hopper for receiving shkvara, sifting and packing shkvara (Technology of meat and meat products / Under the editorship of I. A. Rogov - M: “Food industry”, 1988 - 376 p.). The disadvantages of this line is the very process of complex instrumentation, since the line is of a periodic type, this line occupies a large area.

A known line for the production of fats from raw materials of animal origin, which consists of a spinning top, a boiler for heating raw materials, pumps, a grinder for grinding grease, a settling centrifuge, a final grinding machine, a heater, a separator, a tank, a finished fat pump, a pump for sludge (Meat and meat products / Under the editorship of A.S. Bolshakov, L.M. Rain, N.P. Yanushkin. - M.: "Food Industry", 1976, p. 211). The disadvantages of the line are low operational capabilities, high energy intensity.

The objective of the utility model is to create a line for the production of fats from raw materials of animal origin, reducing the energy intensity of the technological line, as well as expanding the range of lines for processing animal raw materials.

The technical result is to obtain premium fats with a sufficient degree of purification.

This is achieved by the fact that the production line of fats from raw materials of animal origin, including a spinning top, boilers for heating raw materials, pumps for grease mass, a grinder for grinding grease mass, a settling centrifuge, a machine for fine grinding, a tank heater, a separation device, a tank, a finished pump grease pump for sludge, located in the technological sequence, as a device for separation contains an ultrafiltration apparatus. Integration of the ultrafiltration apparatus into the line for the production of fats from animal raw materials ensures the efficiency of the process of purifying fat raw materials due to membrane filters, and the choice of membrane type depends on the type of raw material (beef, pork, lamb, etc.).

Figure 1 shows the line for the production of fats from raw materials of animal origin.

The line for the production of fats from animal feed contains a spinning top 1, boilers 2 for heating the raw materials, pumps 3, 8 and 10 for grease mass, a grinder 4 for grinding grease mass, a settling centrifuge 5, a machine 6 for fine grinding, a heating tank 7, an ultrafiltration apparatus 9 , tank 11, finished fat pump 12, sludge pump 13.

The line for the production of fats from raw materials of animal origin works as follows. Grease, pre-crushed on top 1 (6-12 mm), enters the boilers 2 for heating at a temperature of 45 ° C. The liquefied mass is pumped by pump 3 for grinding into a grinder 4 and then to a settling centrifuge 5, where it is separated at 45 ° С

the bulk of raw shkvara (up to 90%). Then the fat mass is transferred to the machine 6 for fine grinding, the resulting emulsion is transferred to the heating tank 7 for heating to a temperature of 90 ° C and then by the pump 8 to the ultrafiltration apparatus 9 for the final purification of fat. The insufficiently filtered emulsion with impurities is again fed to the heating tank 7 by melting the fat using a pump 10. The ultrafiltration apparatus has a much lower energy intensity than the separator, but at the same time it allows more efficient separation of the protein and fat fractions, and the objective production of fat is higher. From the ultrafiltration apparatus 9, the feedstock enters the tank 11, and then for cooling and packaging. Fat is obtained in the highest grade (water content not more than 0.1%). Impurities (sludge) from the ultrafiltration apparatus 9 are automatically unloaded and pump 13 are sent for further processing.

The proposed utility model does not require large operating costs, but at the same time it allows to reduce the energy intensity of production and to obtain high-purity fat and can be used in the food processing industry.
