Description

The utility model relates to the food industry, namely to technological processes for processing waste from alcohol and sugar production and can be used in the production of feed for farm animals from alcohol stillage, beer pellets or beet pulp.

From the description of the patent of the Russian Federation No. 2238492, IPC7 F 26 B 17/04, publ. 2004, a drying unit is known for drying, including beet pulp. This drying installation contains several belt conveyors installed parallel to each other in the chamber, finger agitators, a drive mechanism, a system for supplying heat to the drying product, a control panel and a distributor for evenly distributing the drying product to the upper working branch of the conveyor belt, while adjacent conveyors are installed with the possibility of rotation of the belts in opposite directions, the odd rows of conveyors are shifted towards the distributor by the same amount in length, and in us shielding plates, and feed coolant into the drying chamber two lines provided protivohod material being dried, the first pipe is directed to the output of the third conveyor and the second pipe - at the last exit conveyor in the unloading area of the window. The disadvantage of this dryer is its low operational reliability and not high enough product quality.

Known dryers of grain and bulk materials (see, for example, patents of the Russian Federation for inventions No. 2146032, 2159403, 2201566 and Patents of the Russian Federation for utility models No. 40449, 40448) have a common drawback - they are not suitable for processing a product with high moisture saturation (more 60%).

In the patent of the Russian Federation No. 2244439, IPC 7 A 23 K 1/06, publ. 2005 described a production line for drying a suspension of post-alcohol stillage stillage, which includes a pump that takes the stillage directly from production and feeds the clarifier through a pipeline, where the incoming stillage is forcedly filtered to obtain filtrate and sediment, a pipe collector connected to the outlet of the illuminant filtrate and separating the filtrate into two flows in a ratio of 1: 2, of which the smaller returns to production, a coagulator connected to the output of the collector with a large diameter, a mixer, which is connected to the outputs of the clarifier sludge and coalescer and wherein the mixing takes place with the precipitation feed additives and mineral supplements, conveyor, feeding the mixture from the mixer to the dryer, and a conveyor feeding the dried material from the dryer to seal - shaping unit of bulk fodder. The disadvantage of this line is the limited technological capabilities and low productivity due to the limited filtration rate.

In US patent No. 4552775, NKI 426/624, publ. 1985 A production line for the production of high-quality animal feed is described, including lines for

the supply of post-alcohol stillage and the removal of solid and liquid products of its processing and interconnected by means of interoperational transfer dryer, a sifting device and a drum in which part of the dried product is mixed with fresh stillage coming from the stripping column, thus, one part of the protein-vitamin product is discharged on packaging, and the other is returned back to the manufacturing process. The disadvantage of such a production line is its low productivity due to the limited throughput of the screening device, drum, and dryer.

A production line that implements a method of producing feed additives for livestock has the same drawback, including lines for supplying post-alcohol distillery stillage and removal of solid and liquid products of its processing, and a centrifuge-based dewatering device connected to each other by means of interoperable transmission, a drying drum connected with a device for concentrating the filtrate, made in the form of an evaporator located at the outlet of the line for the removal of liquid processed products, a granulator and a collector finished products (see the description of US patent No. 5260089, NKI 426/624, publ. 1993).

From the description of the patent of the Russian Federation No. 2217490, IPC7 C 12 F 3/00, 3/10, publ. 2003, a production line for the production of protein and vitamin product is known, including lines for supplying post-alcohol stillage and removal of solid and liquid products of its processing and interconnected by means of interoperational transfer (various conveyors, for example, screw, belt, pipelines) an intermediate tank, a device for dehydration, a dryer, a device for concentrating the filtrate located at the outlet of the line for the removal of liquid processed products, a granulator and a collection of finished products. The device for dewatering is made in the form of a vacuum filter, and the device for concentrating the filtrate is in the form of a separator. The disadvantage of this production line is its low productivity due to the limited throughput of the dewatering device, made in the form of a vacuum filter. In addition, the presence of a dryer in which drying is carried out with dry hot air leads to a decrease in the biological value of the protein-vitamin product due to high drying temperatures, and due to the high speed of the drying agent, it becomes necessary to use a cyclone to clean it.

The technical result of using the utility model is to increase the productivity of the production line for the production of protein-vitamin product.

The vertical chamber of the microwave drying 6 (figure 2) contains microwave generators 16, each of which is placed in a casing with inlet and outlet nozzles and is made of several, two or more low-power magnetrons with individual power sources, an exhaust fan 19, two discharge fan 17 and a heat generator 18, and in the direction of the dried material is divided into zone I of the drying agent of the microwave heating, zone II of heat heating and moisture removal and cooling zone III, microwave generators 16 are installed on wide walls of the drying chamber against opolozhnyh

Block 8 (figure 2) is connected to the sensor 21 of the upper level of the receiving hopper 5, the sensor 22 of the lower level of the receiving hopper 5 and the sensor 23 of the temperature of the vertical chamber of the microwave drying 6. The outlet hopper 7 includes a lock gate 24.

The claimed production line for the production of protein-vitamin product operates as follows.

Alcohol bard from the distillation apparatus, beer pellet or beet pulp from the bioreactor (not shown in the drawings) via line 1 enters the intermediate tank 2, where they are accumulated in the amount necessary for the smooth operation of the production line. From the intermediate container 2 by means of 3-2 (for example, a ladle conveyor), the distillery stillage, beer pellet or beet pulp are fed into the screw press separator 4, where they are separated into liquid and solid fractions. The liquid fraction with an alcohol content of 3 ... 5% and suspended particles ≈1% through the line 13 is fed back to production. The solid product (loose mass with a bound moisture content of 40% to 60%) is fed into the receiving hopper 5 of the dryer using a means 3-2 (this is usually a screw conveyor), a vertical drying chamber for microwave drying 6 passes through the lock gate 24 of the outlet hopper 7 and goes to the granulator 11. The dryer works like this. First, the discharge fans 17 of the air cooling system of the magnetrons of the microwave generators 16 and the heat generator 18 are turned on. After this inclusion, hot air is supplied to zone “II” of the microwave drying chamber 6 and cold air to zone “III”. Further, with the closed lock gate 20, which is the regulator of solid product flow, the microwave drying chamber 6 is filled through the receiving hopper 5 with a solid product - the extraction of alcohol stillage or beer grains. Before entering the zone “I”, the product flow by the upper edges of the boxes 20 is divided into several for a more uniform distribution in the zone “I” of microwave heating. In the process of filling the product is blown with hot air from the heat generator 18 and preheated. After filling in the zone “I”, the power of the magnetrons of the microwave generators 16 is turned on and the lock gate 24 is opened so that the product, when passing through the microwave drying chamber, is released from moisture to the desired condition. In the microwave drying chamber 6 in zone "I", the product is irradiated with microwave energy generated by microwave generators 16, and under its own

weighs down, sequentially bypassing zone “II” and zone “III”, into the outlet hopper 7. In order to ensure uniform heating in volume, the microwave emitting horns are oriented horizontally from the sides. Horizontal microwave emitting horns (not shown in the drawings) are mounted in the windows of the ends of the microwave drying chamber 6 and are closed by radio-transparent plugs (not shown in the drawings). Hot air saturated with moisture extracted from the product is discharged from the microwave drying chamber 6 through the duct 20 using an exhaust fan 19. The dehydrated hot product is lowered by gravity into zone “III”, where it is blown with air pumped by the fan 17 through the air cooling system The microwave generator 16, fed through a pipe into the space under the Λ-shaped boxes 20, is cooled and discharged through the outlet hopper 7 into the granulator 11. Cooling air is removed from zone “III” through the Λ-shaped boxes 20 and the branch pipe 25, to to which exhaust ventilation can be connected (not shown in the drawings).

The specificity of microwave drying is that under the influence of microwave radiation, moisture from the inside of the particles is squeezed out to the surface, and dry hot air is removed from the surface, the temperature of which does not exceed 60 ° C. To control this temperature, a temperature sensor 23 is installed in zone I of the microwave heating. Sensors 21 and 22 regulate the filling rate of the receiving hopper 5 of the dryer by controlling the operation of the means 3-1. After the dryer, the product at the outlet of outlet hopper 7 has a moisture content of ≈20% and can be granulated in granulator 11. From granulator 11, product 3-3 (for example, a conveyor belt) enters the finished product collector 12, from where it is fed via line 14 to packaging. The dry matter content in the finished product is 85 ... 90%, and the protein in it can reach 40%.

The implementation of the utility model makes it possible to obtain a protein-vitamin product of high quality, since low-temperature microwave drying eliminates protein degradation, ensures the preservation of vitamins and disinfects food, while the production line can be equipped with equipment that provides the necessary capacity for distilleries, for example, screw presses a separator with a capacity of more than 80 m ³ / h, a dryer with a capacity of 5 t / h and a granulator of the same capacity. The technology implemented by the production line minimizes the damage to the environment. All this allows us to conclude that the claimed technical solution will take its rightful place among the technologies that ensure the disposal of alcohol stillage, beer pellets or beet pulp.
