The invention relates to agriculture and can be used for production of poultry and pig farming, processing poultry manure and pig manure, production of feed additives in industrial poultry and livestock.

The known method, including the formation of a stock of fresh litter, aerobic and anaerobic digestion of its first and second parts, the removal of excess moisture from the remaining part of the fresh litter. That you are carrying out the pyrolysis its third part, disinfection and drying of the residue of the litter, the separation of this residue as a dry organic fertilizer fourth part of the litter, sanitary and veterinary treatment, vitaminizirovanniy, chopping and mixing the remaining fifth of the litter as a feed additive with bird feed for the use of unspent litter biochemical energy when feeding birds received feed mixture. Regulate the amount remaining fresh litter when submitting it for deletion from the remaining litter excessive moisture depending on the result of calculation of technical and economic index of increase profit of the technological processes of aerobic and anaerobic digestion, pyrolysis, get dry organic fertilizer, receipt of food additives (see RF patent №2327675. Ways and the control device is economical processing of poultry manure in commercial poultry production. / Auvin, Vrgroup, Vgirl // BI. 2008. No. 18).

The disadvantages of this method are the difficulty and complexity of its intended use for in-house production of feed mixtures in poultry and pig production.

The known method, including the introduction of the manure worm in compositename substrate and subsequent separation of worms from the vermicompost (see RF patent 2 255 077 C1, C05F 3/00, A01K 67/033. The method of producing vermicompost. / Abbrechen, VII, Alexei Ivanov // BI. 2005. No. 18). Also known a technique in which the rain (compost) worms continuously migrate and work in periodically added the substrate (see patent RF 2 255 078. C1 C05F 3/00, A01K 67/033. The method of producing vermicompost. / Son, Intitul, LVB // BI. 2005. No. 18). There is also known a method of production of vermicompost containing the addition of sawdust, shavings, small chip to substrate chicken manure, followed by mixing and hydration (see RF patent 2205163, CL C05F 3/00, 2003).

The disadvantage of these methods is the use, in particular, only chicken manure as substrate. Toxic properties of the litter and present it heavy metal salts do not provide organic vermicompost, therefore, biologically clean environment for breeding the worms themselves and their further use for the production of feed and pisew the x additives.

There is also known a method of production of vermicompost containing the separation of worms from the humidified vermicompost (see RF patent 2 274 628. C2 C05F 3/00. Method for the production of vermicompost. /Nasair, Adieksodo, Vasiliev, Ayuhanov // BI. 2006. No. 11). Used red Californian worms Eisenia foetida. Bait in the separation of worms from the humidified vermicompost - a mixture of paper dust, fine sawdust, urea and starch paste. Substrate-technical slaughterhouse blood of slaughtered animals, bones, skins, the contents of the gastrointestinal tract, such as kanagi. Added organic rippers, such as sawdust, paper, residual brewer or Baker's yeast. Put 10...15 worms per 10 kg of processed compost. Red Californian worm (PCC) is a new breed of an earthworm. It belongs to the genus Eisenia foetida. The resulting hybridization of two earthworm species in California in 1959. Worm length reaches 10 cm, has a diameter of 3...5 mm, a weight of about 1, the Offspring of two worms can reach 1,5 tycooly per year. After 40 days, the population doubled. Lives 16 years. Sexual maturity is reached at 90...120 day life. Works most active when the temperature of the substrate 15...25°C. Environment habitat - special substrate, saturated organic compounds, but not the soil. Daily QC who eats 2 times more food than its own weight. Intensive reproduction - when the pH of the medium pH 6,5 7,5.... Grows on the protein raw material. Requires nitrogen sources for its development in a fairly large number (at least 12...16% of the total diet). The flour obtained from the grown PCC, tastes like veal and contains 67% protein, 20% fat, 7...8% carbohydrates. After cleaning PCC can be used as an additive in obtaining sausage and other products. PCC method 3 according to claim 1 of the claims of this method after separation from the vermicompost use again. Mode 4 according to claim 1 of the claims of this method after separation from the vermicompost is dried and used as feed additives for animals or protein additives for the production of meat products.

The disadvantage of this method is the use of only slaughterhouse protein substrate, as manure worms do not grow on the protein raw material.

A common shortcoming of these four methods and some other similar technical solutions is the difficulty their direct use in agricultural production of feed mixtures in the production of poultry and livestock.

The reason for this is the difficulty of automation of processes of preparation of substrates on the basis of the avian is his litter and swine manure, environmentally friendly drying grown manure worms.

Currently in agricultural production, particularly poultry, are implemented quite well-known methods and devices economically rational automated control of technological processes (see RF patent №2229155. Method and device economical General heating of the facility and local heating of farm animals. / Auvin, Vrgroup // B. I. 2004; No. 14; RF patent 2296464. The way to manage economical heating in livestock and poultry and device for its implementation. / Auvin, Vrgroup, Web, BEA // BI. 2007. No. 10; RF patent №2297761. The economical way of heating farm animals or poultry and device for its implementation. / Auvin, Vrgroup, BEA // B. I. 2007. No. 12;

It is known that up to 40% and sometimes even more chemical energy feed nutrients are absorbed, birds, respectively, is not converted to meat or egg and stand out from the body in the form of bird droppings. Meanwhile, the cost of feeding livestock is not less than 70% of the cost of poultry products. Therefore, there is a significant reserve (ideally obvious to the values of 28%) improve technical and economic efficiency even this highly automated industry of agriculture. However, at the present time, this theoretical resource is fully used almost completely insufficient, although in various fields of science and technology appeared and practically tested previously known and new methods of energy evaluation of the digestibility of a biological object nutritional energy, energy-saving selective decontamination of exposure to pathogens and changes in the phase state of matter. Among these methods, which can be used to improve automated technologies-waste recycling litter, distinguished low-temperature pyrolysis, electrical engineering, nanotechnology and management of the largest techno-economic indicator, the analysis of the energy efficiency of new technology in General. So it is timely and relevant, is adding to the existing methods, methods and techniques for more extraction of energy from the litter by partial mixing to bird poop and the fermentation of the remaining litter in biogas digester really modern scientific and technical methods and measures.

Under the existing technologies of feeding, for example, broiler chickens in floor maintenance in some cases (accidents in heat or electricity, microclimate and other) races the od of purchased feed and purchased energy can achieve such values, what is the difference between the higher cost of sales Cpmaxand a very high total cost spent to purchase food With thetomaxand purchased energyemaxwill be quite small. This means that the profit in this (old) version of management by the criterion of maximum productivity of livestock and purchase the stern and the energy received small:

In the proposed system is economically optimal way (economically best) control, the unit automatically selects this mode the minimum expenditure and also significantly cheaper own production of feed mixtures with droppingsCPOTPand the amounts of purchase and own energy in the processing of litter and manure FromEPwholesalewhere specified economically optimal difference Cpwholesale-CCPwholesale-CEPwholesalealways has the highest value. Thus, whatever the external conditions, the profit of production in the new version of management by the criterion of maximum profit Poptalways max:

Subtracting the second difference its first value, the resulting increase in profits Δ, obrazovavshijsya in the optimal (best) automated control of the distribution of own production of feed mixtures with litter and cheaper own production energy:

where:

Δmax- the estimated loss of value of production animals and birds in the transition from control by the criterion of maximum productivity at any cost, feed and energy to economically optimal management according to the criterion of maximum revenue at minimum cost feed its own production and energy of its own production;

ΔTomax- cost savings on food due to new economically optimal management of technology of cultivation (content) and for savings on purchased feed when replacing it with a food of own production of agricultural products of own production and mixing it first (ponetnoi) and second (worms) feed additives;

Shown: Δsupplements- forecast estimated revenue in the economically optimal control; PSFWHOLESALE- economically optimal (best) value of the total consumption of fresh litter and manure PSFunder appropriate conditions of microclimate technology of building of the house 12 or pigsty 13, workshops environmentally friendly drying poultry manure 15, plant cultivation and drying of the manure worms 16; tn1<tn2<tn3possible correlation of the values of air temperatures in the technological areas of the line equipment for environmentally friendly drying of the litter and the production of dry manure worms; PSFmax productthe higher the productivity of the production line of environmentally friendly drying of the litter and the production of dry manure worms.

the automatic control System for economically optimal management workshop environmentally friendly drying poultry manure and plant cultivation and drying of the manure worms works as follows.

Computing unit 35 according to the dimensions and job production parameters worms, dung and manure, microclimate, climate, equipment and formation of the artificial values of the controlled parameter flow rate of fresh litter or manure calculates the target optimization function for each of the two feed additives Δsupplements1,2in the selected range RSF3for polling loop automation system under consideration biotechnical system of the house or barn. The control units 36 and 37 are extreme (maximum) value and the corresponding cost best (optimal) value function argument, i.e. the economically optimal value of the estimated revenue from the production of both feed additives - worms and dry litter. Then these values served as the setting signals for setting the inputs of the regulators part of the fresh litter 38 or manure 39. They correspond to the maximum profit increase production of additional products or two high-calorie feed additives in the form of dried worms and organic dried bird droppings. The regulation of flow through pomestnogo 40 and manure 41 pumps are automatically installed economically optimal values of consumption is part of the fresh litter and pieces of fresh manure (figure 5 shows the optimal total consumption of fresh litter and manure P SF3 wholesale).

For example, it is obvious that at low outside temperatures the costs of manure drying and heating of the compost with worms increase. Therefore, the estimated value of the maximum profit increase production of both feed additives is reduced, and cost the best value of consumption of litter and manure should also decrease (see figure 5). With adequate and accurate mathematical models for concrete structures drier litter and worms and compost storage for breeding worms these procedures are easily performed by the computing unit 35.

Technology of complex processing of parts of poultry litter and swine manure in two specified feed additives is on the cost of the best path. Providing a cost-best technologies for processing part of the litter and manure for the enterprise as a whole the ratio between received new additional poultry products (dry decontaminated manure, dried worms) and spent on processing technology part of the litter and manure energy source of any kind.

Complex waste pig and poultry with its own feed production and energy provides significant savings in the purchase of feed and energy and, under certain conditions, even complete rejection of them, the exact economic optimization of the technological mode of complex processing of litter and manure, as applied to the control obtained from studies of the technological processes of mathematical ratios and used the measured and generated signals and constants carry accurate and complete information about the managed process.

Thus, the proposed complex is a new, technically and economically efficient set of automated technologies co-production of feed additives, energy and fertilizer from poultry litter and swine manure. At the same time fully decided becoming very relevant to industrial poultry production, pig production the following tasks.

4. Additional energy savings at the facility in the extraction result of anthropogenic energy (mixture of inorganic combustible gas, diesel fuel) by low-temperature pyrolysis after removal of excess moisture from the third part of the litter and manure.

5. Production of commercially attractive for producers of agricultural crop products environmentally friendly organic fertilizer by low temperature drying of the fourth part of the litter and manure.

6. Significant savings combined fodder, especially for pigs and poultry, due to the use of bioconversion energy from the rest of the parts produced by bird droppings and can be added to the basic feed for poultry and pigs, as well as through protein energetically valuable supplements based on dried manure worms.

7. Purification from harmful organisms and unpleasant smells the air around each of the house and the barn and around the poultry and pig farm.

8. The final elimination of the serious environmental problems of modern industrial pig and poultry on poisoning raw bird litter and swine manure adjacent to the poultry and pig breeding complex land.

It is obvious that the proposed technology assetsassets separate automated technologies for processing poultry litter and swine manure. It naturally implies a redistribution of their efforts in different seasons: summer - mainly operate digesters (in the southern regions of the country) and the agricultural system, in spring and autumn emphasis on the production of biohumus and dry inorganic fertilizers in the production of feed additives and combined feed mixtures (Pro stock) and pyrolysis energy. Agrocomplex operates in the spring and summer. The workshop for the production of manure worms and feed mill can operate year-round.

In the result of implementation of the described technologies in poultry and pig farming enterprise instead of heavy problems with the environmentally hazardous semi-liquid bird litter and swine manure gets new useful and quite marketable products focused primarily on private consumption for the production of feed and energy. It is the humus in the compost moist organic fertilizer, dry organic fertilizer, dry inorganic fertilizer, fuel gas methane, a mixture of combustible gas and diesel fuel, biological protein Supplement based on dry worms, high-calorie own feed production for poultry and pigs.
