The technical objective of the invention is to create feed additives with vacuum pan coating of a protein-vitamin-lipid complex, which ensures a more uniform distribution and a high degree of penetration of the protein-vitamin-lipid complex, reduces fragmentation of the product, and helps expand the range of produced balanced feed additives with a scientifically proven protein content. vitamin-lipid complex, creation of feed additives with adjustable physicochemical properties, increasing their digestibility, achieved through the use of a protein-vitamin-lipid complex.

The stated technical objective of the invention is achieved by the fact that in a technological line for the production of feed additives with vacuum pan coating of a protein-vitamin-lipid complex, including production bins with dispensers installed in a technological sequence, screw feeders, a separator, a crusher, a mixer, a vacuum sprayer with nozzles, characterized in that that the line consists of five modules: a cleaning and grinding module, a macro-dosing module, a micro-dosing module, a mixing and panning module and a finished product packaging module; in this case, the macrodosing module includes three blocks of hoppers, each of which is equipped with an individual screw conveyor for loading the initial macrocomponents, as well as an individual feeder-doser for dosing into portion strain gauge scales, the microdosing module includes three blocks of hoppers for microdosing microcomponents, each of which is equipped with an individual feeder-dispenser for dosing into strain gauge scales for microdosing, the mixing and panning module includes a vacuum panning machine, an installation for introducing amino acids in a liquid state, an installation for introducing vitamins in a liquid state, an installation for introducing high-viscosity liquid components, which are connected to vacuum spray nozzles for introducing liquid solutions of amino acids and vitamins, as well as high-viscosity liquid components; in addition, the line is additionally equipped with elevators with local filters, a magnetic column, a grain separator and z-shaped conveyors.

In fig. Figure 1 shows a diagram of the technological line for the production of feed additives with vacuum pan coating of the protein-vitamin-lipid complex.

The technological diagram of the production line for feed additives with vacuum pan coating of the protein-vitamin-lipid complex (Fig. 1) includes the following equipment: elevators 1, 11, 23; local filters 10, 12; filter 2; sluice gate 3; screw conveyors 4, 13, 16, 22, 26, 28; magnetic column 5; grain separator 6; bunkers 7, 29; changeover valve 8, 15; hammer crusher 9; valves 14, 15; block of bunkers for macrodosing 17; feeder-dosers 18, 19, 20, 30; strain gauge scales 21; microdosing unit 24; strain gauge scales 25 for microdosing; disc valves 27; mixer 31; mixing hopper 32; z-shaped conveyor 33; vacuum panner 34; weighing machine 38; finished product hopper with packaging 39; installation for introducing high-viscosity liquid components 35; installation of input of amino acids in liquid state 36; installation for introducing vitamins in liquid form 37.

Distinctive features of feed additives with vacuum panning of the protein-vitamin-lipid complex are:

- they must contain scientifically proven levels of protein, lipids, metabolic energy and vitamins and have low crumbability;

- for better absorption of feed additives, thermolabile components (vitamins, amino acids, etc.) must penetrate deeply into them due to vacuum panning and coating their outer surface with a highly viscous lipid complex.

The technological process for the production of feed additives with vacuum panning of the protein-vitamin-lipid complex includes the following main operations: cleaning and grinding of the main components (grain raw materials, bran, meal, etc.); macrodosing of main components; microdosing of components (premix, enzymes, biologically active additives (BAA) and other microcomponents); mixing macro- and microcomponents; vacuum panning with a protein-vitamin-lipid complex by alternately applying liquid solutions of amino acids and vitamins, as well as high-viscosity liquid components to the surface of feed additives, packaging of finished products.

The proposed technological line for the production of feed additives with vacuum pan coating of the protein-vitamin-lipid complex works as follows (Fig. 1). The components (each individually) included in the feed additives (grain raw materials, bran, meal, etc.) are fed using a elevator 1 and a screw conveyor 4 into a magnetic column 5, in which they are cleaned of metal impurities.

Then the components of feed additives, cleared of metal impurities, are sent to the grain separator 6, in which they are freed from non-feed waste, and loaded into the production hopper 7. From the hopper 7, feed additives, using a changeover valve 8, are fed into a hammer crusher 9, in which they are crushed to the desired size. granulometric composition. The resulting dust fraction is sucked off and sent to a local filter 10 to clean the exhaust air. The feed additive, crushed to the required size, is fed using a elevator 11 into a screw conveyor 13, from which, using valves 14, screw conveyors 16 and valves 15, it is sent to the corresponding hopper 17 for this feed additive, i.e. Each feed additive (grain raw materials, bran, meal, etc.) is loaded into its own separate hopper 17. The dust fraction formed in the elevator 11 during the movement of the corresponding feed additive is sent to a local filter 12 to clean the exhaust air.

Then, from each bin 17, a different type of feed additive is loaded into portion strain gauge scales 21 using appropriate feeder-dosers 18, 19 and 20, which weigh out certain portions according to the recipe.

Next, weighed portions of the mixture of feed components are fed using a screw conveyor 22 into an elevator 23. The dust fraction formed in the elevator 23 during the movement of the mixture of feed components is sent to a local filter 12 to clean the exhaust air.

The mixture of feed components coming out of the elevator 23 is fed by a screw conveyor 28 into a hopper 29, from which it is fed into a batch mixer 31.

At the same time, the microdosing installation 24 forms a mixture of a given composition: for this, from the hoppers of the installation 24, microdoses of components using feeder-dosers 30 are fed into strain gauge scales 25 for microdosing, from which the mixture of microcomponents is loaded into the mixer 31 by a screw conveyor 26 using a disc valve 27 .

The separate formation of macrodoses of main feed additives in the macrodosing module and microdoses of the corresponding components in the microdosing module is due to the laws of their mixing to obtain a homogeneous mixture.

After loading the macro- and microcomponents of the feed additive, the lid of the mixer 31 is closed, its drive is turned on, and the mixture is prepared. Separate formation of macro- and microdoses before feeding into mixer 31 makes it possible to achieve high homogeneity of the resulting mixture when mixed in a quasi-weightless state.

Then the mixer 31 stops and the prepared mixture is unloaded into the sub-mixing hopper 32, from which, using a z-shaped conveyor 33, it is sent to the vacuum paneer 34. After loading a certain portion of the mixture into the vacuum paneer 34, the loading valve is closed and air is pumped out of it with a vacuum pump and created vacuum 0.02-0.04 MPa. Due to the fact that the prepared mixture is in a vacuum, air is completely removed from the pores of its components. Then, mixing of the mixture begins in it and, through nozzles, a solution of amino acids from an installation for introducing amino acids in a liquid state 36, a solution of vitamins from an installation for introducing vitamins in a liquid state 37, and high-viscosity liquid components (fats, oil, phosphotides, etc.) from installations for the introduction of high-viscosity liquid components 35. Separate preparation of a solution of amino acids, a solution of vitamins and high-viscosity liquid components with their subsequent introduction allows us to achieve a scientifically based content of the protein-vitamin-lipid complex to obtain balanced feed additives.

Liquid components are introduced into the vacuum pan coater 34 through a manifold with nozzles located along the entire length of its working chamber, which allows for uniform distribution of liquid components over the surface of feed additives. In this case, the liquid components are finely sprayed over the layer of the mixed mixture; the design of the nozzles of the vacuum panner 34 ensures a stable and uniform supply of liquid components with minimal energy consumption.

Installations 35, 36 and 37 include a pump with a drive, a set of measuring and control equipment and instruments, pipeline fittings, allowing the operator from the control panel to set a certain flow rate of liquid components, control and, if necessary, adjust it. Vacuum pan coater 34 ensures uniform distribution of the introduced components over the surface of feed additives, high operational reliability and performance. At the end of the operating cycle, the vacuum panner 34 is disconnected from the vacuum line and the valve connecting to the atmosphere smoothly opens. Due to the pressure difference created, the efficiency of the process of diffusion of liquid components inside feed additives is significantly increased, from the pores of which, due to vacuuming, trapped air is removed, which prevented the penetration of the protein-vitamin-lipid complex. Then the unloading valve in the vacuum panner 34 opens and feed additives with an applied protein-vitamin-lipid complex are unloaded into a z-shaped conveyor 33, from which they are fed into the finished product hopper 39.

From the finished product bin 39, feed additives coated with a protein-vitamin-lipid complex are sent to a weighing machine 38 for packing into bags for further sale.

Thus, the use of the invention will allow:

- create feed additives with a scientifically proven content of protein-vitamin-lipid complex, maximally adapted for various species and groups of farm animals and poultry, in order to increase its accessibility to digestive enzymes;

- increase the digestibility of produced balanced feed additives by optimizing the protein-vitamin-lipid complex, achieved due to a more uniform distribution and high degree of penetration of the protein-vitamin-lipid complex deep into the feed additives;

- satisfy the internal needs of the Russian markets for feed additives with vacuum pan coating of the protein-vitamin-lipid complex;

- the use of feed additives with controlled physical and chemical properties and with a scientifically proven content of the protein-vitamin-lipid complex will expand the range of produced feed and increase their digestibility.
