Diseño preliminar del proceso para la producción de colágeno hidrolizado a partir de subproductos de la industria de beneficio animal

Abstract

Abstract:The generation of by-products in animal benefit centers represents an environmental and economic problem. By-products such as bovine and porcine hides and bones have a high collagen content. It was proposed to revalue the waste through the preliminary design of a process for the extraction of hydrolyzed collagen. As a result, a system of 8 units was obtained that perform removal, extraction, separation, precipitation, purging and drying operations. Jacketed mechanical agitation tanks, decanters, a precipitator and a rotary dryer were dimensioned in detail. The production capacity is 78.8 tons of product that comes from 674.10 tons of by-products, being 85% the yield. The collagen presented 98% purity, with a sale price of $34.00/kg. The FCOP of the plant was 713.59 thousand dollars and the CCOP was 2091 thousand dollars per year, which meant a cost of 26.53 $/kg of product. The economic analysis determined that the TRI equal to 2 years and the ROI of 45.86% at the fifth year, demonstrating that the proposal is feasible.
