Aprovechamiento de la sangre de faena mediante la producción de harina de sangre por el método de secado spray

Abstract

Use of slaughterhouse blood to produce blood meal by spray drying method. The activity of slaughtering animals for human consumption, such as that performed in the Municipal Slaughterhouse Luis Beltrán SE, generates byproducts that can be considered waste and / or contaminants but, although they need to be treated special, can become usable and tradable manufactures. Blood is very harmful to the environment due to its high content of organic compounds. Treatment of wastewater containing high volumes of blood is more expensive than implementing measures to prevent it is discarded as part of the wastewater and use it as a raw material in any process. The use of the blood of slaughter is an option that allows a source of income through the commercialization of blood meal produced and considering the regulatory framework of production and marketing, it is undoubtedly a benefit to the environment. As there are several technics of producing blood meal, in this work we investigated, identified and compared various methods in order to suggest which is the more appropriate to apply to the Municipal Slaughterhouse Luis Beltrán because of the feasibility of buy and install it, the quality of the final product and the possibility to sell in into the market at local and regional level. The investigation led to the choice of the process of drying blood by spray method because the technique is effectively carried out at temperatures which do not alter the quality of the produced blood meal. Methodology was investigated in depth by calculating the cost of installation of equipment manufactured by renowned companies and production of blood meal ready to sale. Analyzing the current facilities distribution at Matadero Municipal Luis Beltrán the location of the processing plant blood meal by Spray Drying Method is suggested. The following research was conducted as a partial requirement for obtaining the title of Technician in Agro-industrial Processes, awarded by the School of Medical Veterinary and Agro-industrial Processes, Universidad Nacional de Río Negro
