Diseño de un biodigestor que genere biogás para el aprovechamiento del excremento avícola. Authors: Lozano Ruiz, Angie Carolina, Sanchez Montealegre, Cristian Arled

“…The present project consists in the design of a biodigester for the generation of biogas using as fuel the excrement of laying hens raised in the farm " my farm eggs the golden " of the sidewalk the Triunfo, corregimiento the Caguán of the city of Neiva-Huila, as a first step were determined the physico-chemical variables of the mixture between chicken manure and water, for this the chicken was collected produced by 1325 laying hens for six months and from a pig kept on the farm, which would function as a substrate that accelerates anaerobic digestion, as a result an average of 33.46 kg/day was obtained, after collection pH tests were performed at different ratios between hens, and water to define the percentage of mixture with which the biodigester would be supplied, being that of 40% substrate (Chiken manure- swine manure ) and 60% water, the most suitable for the functioning of the biodigester. …”

Diseño y evaluación mediante simulación de un prototipo de máquina extractora de mesocarpio para la granadilla Authors: Segura Hernandez, Daniel Felipe, Clavijo Eraso, Manuel Alejandro

“…According to the research carried out and the calculations carried out, it was obtained that the diameter of the centrifuge is 300 mm with a height of 500 mm, contemplating that 8 granadillas can be processed along the drum, being approximately 800 grams. of the product that can be maneuvered; therefore it is estimated that the maximum lateral load it can bear is 10 Kg; This section of the prototype works by a motor (2 hp for rollers, 0.5 hp for rollers) that drives 1800 rpm, according to the selection made, which will be transmitted to a chain whose relationship is type 06A with chain pitch 9,525 (3/8 "); Now, the centrifuge will operate with a motor and a pulley transmission distributed in turn in two SPA-type belts for a power of 2 hp; Consequently, it is established that the prototype has two power units for each process (peeling and spinning), which simulation and analysis of results was carried out using Autodesk Inventor software, giving parametric level the viability of the prototype, within which highlights the production efficiency whose maximum capacity is 180 kg / h, each spin cycle comprises 30 kg every 10 min; It is said to be efficient and does two processes simultaneously, unlike conventional processes such as hydrolysis or manual.…”
