A disadvantage of the known line is the limitation of the produced granular feed, as well as its low nutritional value.

An object of the invention is to expand the range of manufactured granular feed additives of high quality using waste from the sugar industry (beet pulp and molasses), increase the technological capabilities of the line for the production of granulated feed additives of a given nutritional value, adapted for various types of farm animals and poultry.

The problem is achieved in that in the production line of granular feed additives using waste from sugar industry enterprises containing a receiving hopper, a granulating and drying apparatus, the new one is that the line is additionally equipped with a molasses input unit, which includes: pumps, a receiving tank for molasses, supply tank, filter, safety valve, pressure gauge and molasses counter; a screw feeder is installed under the production hopper, which feeds loose beet pulp in a mixer-air conditioner, to which steam and molasses are simultaneously fed from the molasses inlet installation, after the mixer-air conditioner, a pellet press is installed, from which the feed additive granules enter the cooling column, the cooled granules are sent to a sieving machine, then the granules are fed to the storage hopper, Further, in a weight dispenser for packing granules into bags, which are conveyed by a conveyor belt to the finished goods warehouse.

Figure 1 shows a three-dimensional image of the production line of granular feed additives using waste from the sugar industry, and figure 2 is a three-dimensional image of a production line of granular feed additives (in version 3D).

The composition of the production line of granular feed additives using waste from the sugar industry enterprises (FIGS. 1 and 2) includes: a production hopper 1, a screw feeder 15, an air conditioning mixer 2, a pellet mill 3, a cyclone battery 4, a cooling column 5, a sieving machine 6, the storage hopper 7, the weighing batcher 8, the conveyor belt 9 and the installation of the input molasses. The installation of molasses input includes: pumps 11 and 14, a receiving tank for molasses 10, a supply tank 12, a filter 13, a safety valve 18, a pressure gauge 17, and a molasses counter 16.

Beet pulp is a sugarless chip remaining after sucrose is extracted from it in a diffuse way and contains nutrients. These are crude protein, crude fiber, nitrogen-free extracts, protein, vitamin C, and essential amino acids (lysine, treanine, valine). Up to 30-35% of bagasse is fed fresh by farm animals, the rest is acidic, and up to 5% of nutrients are lost and its quality is significantly impaired. Feed value of 100 kg of pulp (in feed units): fresh 6-9%, squeezed and granulated 15-20%, acid 9-11% in the total mass of pulp.

Molasses, or feed molasses, is a valuable feed waste of sugar beet production. Molasses is a thick (density 1.38-1.44 g / cm ³ ) viscous liquid of dark brown color. The composition of beet molasses: water 20%, sugar 50, nitrogenous substances (not proteins) 14, ash 11 and other organic substances 5%. Molasses is an intercrystal solution in the form of an outflow, it contains valuable substances (sucrose, soluble non-sugar, trace elements, etc.). A particularly important trace element in molasses is cobalt (0.59 mg per 1 kg), the lack of which in the feed causes a serious disease of ruminants. Molasses is a good fodder product, as it enhances the taste and nutritional properties of compound feeds and has a high nutritional value - 76.8 feed is contained in 100 kg of molasses. units

When ruminant animals are fed with molassed feeds, fiber absorption is increased, which allows the use of feed products with a high content of it (corn cobs, oat husks, etc.). When heated, molasses becomes fluid, easily absorbed by products, forming a dry molasses feed.

In feed mills, molasses is introduced in both loose and granular feed in the following amounts: for poultry of all species and age groups up to 3%, for pigs of all age groups up to 5, for cattle up to 7, for fish up to 3, for sheep up to 7 and for rabbits and nutria up to 7.5%.

The supply tank 12 is equipped with a rotating mixer in the form of a frame.

The production hopper 1 provides the accumulation of a certain amount of loose beet pulp and serves as a consumable capacity when feeding the pulp into a continuous screw feeder 15. The screw feeder 15 feeds loose beet pulp into the mixer-conditioner 2, which simultaneously serves steam and molasses.

The housing of the production hopper 1 consists of an upper rectangular and lower conical parts and is made welded from sheet steel.

The screw feeder 15 provides a continuous, adjustable and uniform supply of loose beet pulp to the continuous mixer-air conditioner 2 for steam conditioning and molassing. The screw of the feeder 15 is made with a progressively increasing pitch of the screw in the area of capture of the product, and in the area of unloading of the product, the screw must be double-entry.

The mixer-conditioner 2 in continuous mode provides the preparation of a homogeneous product when conditioning loose beet pulp with steam or when mixing loose beet pulp with molasses (up to 5%). For the introduction of steam and liquid components in the body of the mixer-air conditioner 2, holes for installing fittings are provided.

Granulator press 3 provides the preparation of feed additives in granular form using beet pulp, steam and molasses. It is installed after the mixer-conditioner 2 and provides uniform supply and forcing of the product through the die of the matrix. The composition of the press granulator 3 includes: inlet channel; pressing section; cutting knives; steam communications; matrix elevator; electrical equipment.

The cooling column 5 provides effective cooling of the granules after the press granulator 3 using ambient air. The cooling column 5 includes a working chamber, a feeding device, a loading and unloading zone. This ensures a tight air supply to the product without loss. If the retention time and setting of the ambient air flow are optimal, then the output temperature of the granules should reach a level of no more than 10 ... 15 ° C above the environment. The exhaust air after the cooling column 5 is supplied to the cyclone battery 4 for cleaning the smallest feed particles.

Installation molasses input provides continuous molasses input in the mixer-conditioner 2 with the ability to maintain a given molasses temperature in the tank. The installation provides measurement of molasses consumption, regulation of its level in the tank.

The sieving machine 6 sorts the granules after the cooling column 5 in a continuous mode, ensuring a uniform product flow through the feeder cone onto an oscillating casing with sieves.

The use of molasses during granulation of pulp - by 5% increases the productivity of the press granulator 3, reduces energy consumption, improves the nutritional value of the feed additive.

The proposed line for the production of granular feed additives using waste from the sugar industry is as follows (Fig.1 and 2).

The technological process of obtaining granular feed additives using beet pulp, steam and molasses includes the following operations:

- supply of dried loose beet pulp to the production tank for further processing;

- conditioning the dried pulp with steam with a pressure of 0.15-0.20 MPa in the mixer-conditioner 2;

- input molasses in an amount of 0.07 m ³ / h (70 liters / h);

- granulation of pulp (granule size up to 10.0 mm);

- cooling of the granules in a counter-current cooling column to a temperature not exceeding the ambient temperature by more than 10 ... 15 ° C;

- fractionation of granules into coarse and fine fractions in a sieving machine 6 with the return of the latter to re-granulation.

- packing of granules in bags on a weight dispenser 8 and their transportation in bags to the finished goods warehouse is carried out by a conveyor belt.

From the production hopper 1, the pulp is sent by a screw feeder 15 to the mixer-conditioner 2, in which it is mixed with steam and molasses.

The introduction of steam is necessary to obtain granules of good quality and increase the productivity of the pellet press 3. The steam installation should be as close as possible to the pellet press 3, this will reduce the steam pressure to 0.15-0.20 MPa and will maintain the pressure at a stable level .

The molasses is added to the beet pulp using the installation of molasses input consisting of pumps 11 and 14, a supply tank 12, a filter 13, a safety valve 18, a pressure gauge 17, and a molasses counter 16. The molasses should be stored in a heated receiving tank 10.

Press granulator 3 compresses the pulp into granules, the size of which depends on the size of the holes of the matrix (usually within 6, 8 and 10 mm).

The granules after the press granulator 3 enter the countercurrent cooling column 5, consisting of a discharge mechanism. Ambient cooled air is fed vertically into the pellet bed. If the retention time and setting of the ambient air flow are optimal, then the output temperature of the granules reaches a level of 10 ... 15 ° C above the environment.

Then, the cooled granules of the feed additive enter the sieving machine 6 to separate the fine particles from the granules. The fine fraction is returned to the press granulator 3 for re-granulation.

Between the storage hopper 7 and the conveyor belt 9 there is a weight dispenser 8 for dispensing granules into bags.

Granulated pulp in bags is sent by a conveyor belt 9 to the finished goods warehouse.

The technology for the production of granular feed additives using beet pulp and molasses improves the technological properties of the product - an increase in bulk mass by more than 1.5 times compared with loose pulp, an improvement in its flowability, which prevents caking of the product and the possibility of storing it in silo containers. Granulated beet pulp is a valuable source of easily digestible carbohydrates, fiber and improves the palatability of animal feed.

The use of molasses in granulation of pulp by 5% increases the productivity of the press, reduces energy consumption, improves the nutritional value of the feed additive.

The use of feed additives in granular form will increase the productivity of animals by 7-10% while saving grain raw materials by 5-8%.

The production line of granular feed additives using waste from the sugar industry will increase animal productivity by 7-10% while saving grain by 5-8%.

Thus, the use of the invention will allow:

- expand the range of manufactured granular feed additives using beet pulp and molasses of a given nutritional value, adapted for various types of animals and poultry;

- to increase the nutritional value of granular feed additives with the directional regulation through the use of beet pulp and molasses.
