The equipment chain includes a mixer, a centrifuge, a defecator, a second centrifuge, a saturator, an ion exchanger, an aerotank and a sump. Utilization products include organic fertilizers, purified water and semi-finished products for the production of sodium glutamine and betaine.

This process can be considered as an alternative to the widespread and popular (mainly abroad) technology of the post-alcohol stillage stillage.

A known standard scheme for producing protein-vitamin product, which consists in drying the post-alcohol distillery stillage / Fuchs A.A. Technology of alcohol production.- M.: Pishchepromizdat, 1951, pp. 483-488, 534-536, Fig. 147 /. Drying equipment includes a scraper conveyor installed in the technological sequence, on which the main mass of water is separated, a filter apparatus and a drying drum. For disposal of the entire liquid part of the stillage, the possibility of using evaporators is provided.

The drying process of post-alcohol stillage stillage is characterized by high energy intensity and low productivity, as a result of which it is currently replaced by a more economical and productive one.

Cl. 426/624, published on 12.11.1985 /, which was carried out on a production line including highways for supplying post-alcohol distillery stillage and removal of solid and liquid products of its processing and, interconnected by means of interoperational transfer, a dryer, sifting

IPC 7 with 12 F 3/00

(Options)

a device and a drum in which a part of the dried product is mixed with fresh stillage coming from the stripping column, thus, one part of the protein-vitamin product is diverted to the packaging, and the other is returned back to the manufacturing process. Obviously, the use of such technology in conditions of periodic shutdowns of alcohol production, for example, for carrying out preventive measures, etc., requires significant costs for its restarting, while ensuring the continuity of the production cycle will be difficult.

To date, this technology is the most advanced, but its main disadvantages include limited technological capabilities in terms of increasing the productivity of the line, for example, the possibility of using this technology at distilleries with a productivity of 4-6 thousand decalitres per day is doubtful. In addition, centrifuges as dehydration devices do not provide a sufficient degree of separation of solid products from post-alcohol stillage and make the protein-vitamin product production process energy-intensive enough, and the significant noise produced by them adversely affects the working conditions of staff.

The problem solved by the second utility model of the group also consists in expanding the technological capabilities of the existing one; its production line for the production of protein-vitamin product.

The technical result will be a further increase in the productivity of the line and the simplification of its design.

To solve this problem, in a well-known production line for the production of protein and vitamin product, including lines for supplying post-alcohol stillage and removal of solid and liquid products of its processing, and an interconnected intermediate container, a dehydration device, made in the form of at least one centrifuge, and the collection of finished products, the line for removal of solid processed products is equipped with at least one device for supplying and removing hot dry air ear, adapted to air interaction with solid products.

Useful models are illustrated by drawings, in which Fig. 1 shows a general scheme of a production line for the production of a protein-vitamin product with options for its execution; figure 2 shows an additional embodiment of the line.

The production line for the production of protein-vitamin product includes lines 1, 2 and 3 for supplying (1) post-alcohol distillery stillage and removal of solid (2) and liquid (3) products of its processing, and interconnected by means of interoperable transmission (various conveyors, for example screw, tape, pipelines, etc. are shown conditionally in the form of lines ending with arrows), an intermediate tank 4, a device 5 for dehydration and a collection 6 of finished products. This is the minimum set of equipment needed to realize the line of its purpose.

In accordance with the author's intention (the first version of the production line), the dewatering device 5 can be made in the form of at least one vacuum filter 7, for example, with a converging web and a continuous tissue regeneration system. Such filters are serially produced by Russian enterprises, and it is not known from the prior art about their use in the alcohol industry for the separation of post-alcohol distillery stillage into solid and liquid fractions, which is obviously due to the need to resolve existing technical contradictions.

The technological capabilities of the line are gradually expanding as it is equipped with the following equipment:

- at least one granulator 8 located behind the vacuum filter 7;

-at least one cyclone 10, at least one of the inputs 11 of which are connected to the ventilation chamber 9, and one of the outputs 12 to the granulator 8;

at least one, for example, rotary-drum dryer 13, located between the granulator 8 and the vacuum filter 7, while one of the outlets 14 of the at least one cyclone 10 is connected to it;

-at least one device 15 for supplying and removing hot dry air, configured to interact with air and solid products and installed on line 2, while one of the inputs 16 of the cyclone 10 is connected to the device 15 for supplying and removing hot dry air;

-evaporator 17 and barometric condenser 18 with a water supply line 19 located on the vacuum supply line 20 between the vacuum filter 7 and its vacuum pump21, while the line 3 for removal of liquid processed products is connected to the evaporator

17 and is made in the form of a shutter 22, which includes at least one intermediate tank 23 for liquid processed products;

- at least one device for concentrating the filtrate, made in the form of a separator 24, located at the outlet 25 of the line 3 for the removal of liquid processed products;

- a mixer 26 connected to the separator 24 and located in front of the granulator 8;

at least one additional mixer 27 associated with the lines of removal of solid products of at least one device 5 for dehydration and at least one dryer 13, while the line of removal of solid products of the additional mixer 27 is connected with granulator 8.

Additionally, to intensify the process of air exchange in the operations of removing excess moisture from the finished product and its semi-finished products, at least one fan 28 is located between the inlet 11 of the cyclone 10 and the ventilation chamber 8. The same fans 29 and 30 are located between the inlet 14 of the cyclone 10 and dryer 13, and between the inlet 31 and the additional mixer 27.

The second version of the production line for the production of protein-vitamin product includes the same minimum set of equipment necessary for the device to be used as the first option, illustrated by the same scheme, it should be noted that line 3 for the removal of liquid processed products comes from device 5 for dewatering directly to the separator 24 in section 32, shown by a dashed line. The invention will be realized if the device 5 for dehydration is made in the form of at least one centrifuge 33, and the line 2 for removal of solid processed products is equipped with at least one device 15 for supplying and removing hot dry air, made with the possibility of interaction air with solid products.

The technological capabilities of the line are gradually expanding as it is equipped with the same equipment as in the first embodiment, with the exception of the already mentioned device 15.

We will consider the operation of the lines in the following; their examples.

Example 1. Illustrates a production line with a minimal set of equipment.

After alcohol, for example, grain bard from the distillation apparatus (not shown conditionally) along line 1 enters the intermediate tank 4, where it is accumulated in the volume necessary for the smooth operation of the device 5. As a device 5 for dehydration, a BOP type vacuum filter with a converging cloth and a continuous tissue regeneration system manufactured by the Russian company Uralkhimmash from Yekaterinburg was taken.

After the vacuum filter 7, the post-alcohol distillation stillage is divided into two streams, one of which includes a solid product, and the other liquid, the so-called filtrate. A solid product looks like a loose mass with a moisture content of 40% to 80%. The filtrate includes 2-4% solids, some of which are in suspension, and some are dissolved. This product is routed along line 3, as a rule, to a sump, and partially to boilers (not shown conditionally), replacing about 75% of the water added to the grain.

The operation of the filter 7 is ensured by the vacuum pump 21. To obtain a deeper vacuum, the line 3 is recommended to be equipped with an evaporator 17 and a barometric condenser 18. In this case, the line 3 at the outlet of the evaporator should include a shutter 22, which, for example, can be made in the form of a sufficiently long vertically installed pipes, the lower end of which is lowered into the intermediate tank 23 with the filtrate. This technical solution allows a fairly simple way to obtain a vacuum value reaching minus 0.95 atm., In contrast to the vacuum pump 24, which provides minus 0, 6 atm.

The design of the vacuum filter 7 on its working surface provides two characteristic zones - filtration and drying. If the vacuum is sufficient, then at the outlet from the filter sheet 7, the solid product can have a moisture content of 50-80%, which allows it to be sent directly to the collection box 6 of the finished product, from where the concentrated product enters the packaging 34, where it is usually packaged in some tightly closing containers. A line of such a configuration provides a protein-vitamin product with a protein content of up to 44%, while a certain amount of solids (up to 2.5%) is lost, falling into the sumps, which to some extent is harmful to the environment.

Example 2. Illustrates the production line with the recommended set of equipment, designed for high productivity and obtaining protein-vitamin product with a protein content of up to 54%.

The operation of the line is similar to the previous example, except that from the canvas of the vacuum filter 7 a solid product having a humidity of 50-80%, using the means of interoperational transmission (this is usually a screw conveyor), is fed to the dryer 13, for example, rotary drum. Prior to this, the solid product, as it moves by the conveyor, interacts with hot, dry air. The device 15 provides this possibility due to, for example, conventional blowing of a moving and stirred product, blowing in a special chamber or blowing directly at the exit from the web, etc. The product after this pre-treatment loses up to 5% moisture, after which it enters the dryer 13, partially prepared, significantly increasing it

productivity and improving working conditions. After dryer 13, the product has a moisture content of 20-25% and can be granulated in the device 8. From the granulator 8, the product enters the ventilation chamber 9, where it is brought to a moisture content of 10-14%, after which it enters the collector 6 of the finished product, is packaged on the device 34, for example, in bags, or poured in bulk in a locked container and transported to a warehouse or consumer.

To increase the yield of the product, the exhaust air from devices 15, 13, and 9 passes through a cyclone-type air purifier — cyclone 10, in which solid particles of the protein-vitamin product are separated, which are then transferred to granulator 8. Almost pure air is released into the atmosphere. To intensify the cleaning, the ventilation chamber 9 and the dryer 13 are additionally equipped with fans 28 and 29.

The parametric reserve of the production line is its equipping; the device for concentrating the filtrate is a separator 24 installed on line 3. Separator 24 allows you to additionally separate up to 2% of solids from the filtrate, which in the form of slurry with a moisture content of up to 75% can be used as an independent product with a protein content of up to 54%, or enter the technological process - mixer 26, where after mixing with a solid product the protein is enriched to its content, for example, 44%. In this case, the granulator receives a wetter starting product. Granules become denser and heavier.

As can be seen from the example, the production line is designed in such a way that removing any device from it (except device 5 for dehydration) does not affect the overall performance. There is only a slight deterioration in operational and, accordingly, economic indicators, for example, the exclusion from the composition of the line of the granulator 8 and the ventilation chamber 9 will lead to the fact that the final protein-vitamin product will have a loose appearance, etc.

Example 3. Illustrates a production line with a possible set of equipment, also designed for high productivity.

The line is equipped with a minimum set of equipment, similar to example 1. In addition, it is equipped with an additional mixer 27, which receives part of the solid product from the vacuum filter 7, which has a high moisture content and the entire product from the dryer 13. From the additional mixer 27 after thorough mixing the product comes out with humidity (for example, 14%), allowing its storage for a sufficiently long time without compromising consumer properties.

When the moisture content of the product is 20-25%, it can be fed into a granulator 8, etc., for example, as described in example 2 and shown in figures 1 and 2.

Example 4. Illustrates the second embodiment of the production line with a minimum set of equipment. The operation of the line is similar to example 1 with the only difference that at least one centrifuge 33 is used as a dewatering device, while the solid waste product return line 2 is equipped with a hot dry air inlet-outlet device 15 configured to interact with air mentioned products. In practice, a centrifuge 33 can provide a product with a moisture content of about 65%, but its productivity will be very low. For this reason, the line should be equipped with at least device 15. The result is a protein-vitamin product with a protein content of up to 38%. Dry weight content; the content in the filtrate reaches 5%. With such fairly low rates, the cost of packaging, installation and launch of the line will be practically minimal.

The disadvantages of the line include not very high productivity, increased noise accompanying the operation of centrifuges 33 and a fairly large energy consumption.

Example 5. Illustrates a production line, the centrifuges 33 are the basis for the dewatering device. Otherwise, the line is equipped with the same equipment as the line in example 2. The load on the separators 24 is increased. As a result, a protein-vitamin product with a protein content of up to 52- 54%.

Example 6. Illustrates a production line based on centrifuges 33, described in example 4 and equipped with additional equipment as in example 3. The selection of a part of the solid product in the additional mixer 27 is carried out at the outlet of the centrifuges. The device 15 for supplying and removing hot dry air (not shown in Fig. 2) also continues to prepare the remaining part of the solid product from the total flow for subsequent feeding into the dryer 13. The physical properties of the finished product are the same as described in example 3.

The implementation of utility models allows you to get a protein-vitamin product that is of high quality, while the production lines can be equipped with equipment that ensures the necessary performance of distilleries. Technologies implemented by production lines minimize harm to the environment. All this allows us to conclude that utility models will occupy a worthy place among the technologies that ensure the disposal of post-alcohol stillage
