Diseño de una planta para el procesamiento de concentrado congelado de maracuyá (Passiflora eduis) por evaporación osmótica

Abstract

The present work shows the design of a plant for the elaboration of frozen passion fruit concentrate by means of osmotic evaporation. The plant will produce frozen passion fruit concentrate in 250 g presentation and frozen passion fruit pulp in a 500 g presentation. The process of obtaining the concentrate includes tangential microfiltration and osmotic evaporation as the main operations. As a by product of tangential microfiltration, passion fruit pulp is obtained. The design criteria considered included percentage losses during sorting, chlorine concentration and water consumption for fruit washing, percentages of bark, seed and starches for pulping and centrifugation, enzyme cocktail concentration and temperature for enzymatic hydrolysis, Permeate flow rate and the volumetric retention factor for the tangential microfiltration and in an analogous way water evaporated flow rate in the osmotic evaporation. The plant will work 5 days a week for 24 hours in 3 shifts, and daily produce two batches from the pulping process. Finally, the economic feasibility analysis was performed with the information obtained throughout the design for a period of 10 years.
