Recycling DDGS design, commissioning, supply of equipment

DDGS contains about 6-9% solids, composition which includes: crude protein, nitrogen-free extractives, fat, fiber, ash, trace minerals and vitamins. Use of DDGS in liquid form is not always rational because of problems with storage, because proteins to walk in its composition after day start to decompose and is not economically advantageous in transportation over its range 5 ... 7 km. In order to make full use of DDGS as a fat-based food offered its multistage processing to obtain the entire range of commercial products used as feed additives and livestock to concentrated feed. Additionally, realization of the proposed technology allows to return to the liquid phase manufacture and vinasse Luthern water, which significantly reduces intake of fresh artesian water for technological needs. In addition, in parallel to address the environmental objective - the protection of soil, surface water and groundwater from pollution products bards of decay that occurs in standard, to date, the method of disposing of DDGS - conditioned in its bardohranilische. Proposed recycling technology is as follows. DDGS from the compartment 06 is cooled in recuperative heat exchanger preheats process media and intermediate, is then passed to decanter where divided into a solid fraction - the cake (40% absolutely dry substance) and a liquid - centrate (5% of the bone dry solids). The cake can be dispensed as a commercial product but it is more efficient drying to obtain a protein-vitamin concentrate - IOO. Centrate to enhance its qualities as a commercial product condenses to install microfiltration to obtain another commercial product - concentrate (22 ... 25% of the bone dry solids). Can be implemented as an independent commodity concentrate product but to improve the nutritional quality IOO, the concentrate is mixed with the filter cake and dry. Waste from the condensation of supernatant - permeate (1.0 ... 1.5% of the bone dry solids) after the correction of its physico-chemical composition is returned to compartment 03 where it is used
