Item Acesso aberto (Open Access) Análise de viabilidade econômica da implantação de uma indústria beneficiadora de açaí no município de Abaetetuba/PA(Universidade Federal do Pará, 2021-10-13) PRAXEDES, Adalberto Malato; CORREA, Alessandro de Castro; http://lattes.cnpq.br/6408989265441974This work analyzed the economic feasibility of implementing an açaí processing industry in the city of Abaetetuba/PA. A structured interview was carried out with the interested investor group in order to understand their objectives and expectations, as well as the project's premises. The average cost of açaí in the harvest and in the off-season was estimated through a survey in the domestic market. The evaluation was carried out based on the discounted cash flow method, the Net Present Value, the Internal Rate of Return and Payback as feasibility indicators. For the Minimum Attractiveness Rate, the cost of capital was adopted based on the beta calculated by the Capital Asset Pricing Model (CAPM) from daily observations of share prices of companies in the Brazilian food sector from 04/01/2018 to 04/01 /2021 and the Selic rate as a risk-free rate. The Monte Carlo simulation technique was used to analyze the uncertainty associated with different scenarios resulting from variations in demand, in the cost of goods produced in the harvest, in the cost of goods produced in the off-season and in the sale price. The results indicated that the project is viable and suggest that there is a 62.82% chance of generating positive results.Item Acesso aberto (Open Access) Protótipo de um secador de grãos rotativo compacto com sistema fotovoltaico(Universidade Federal do Pará, 2023-08-06) RODRIGUES, Benedito de Jesus da Silva; DIAS, Carmen Gilda Barroso Tavares; http://lattes.cnpq.br/2113791118142177 País de Nacionalidade BrasilThe industrial bioeconomy of açaí, a fruit native to the Amazon, produces food with antioxidant phenolic compounds and lipids. Fractions of the pulping by-product are used to generate bioenergy and are being researched as biopolymers, filler for making furniture and architectural materials. With this in mind, two rotary grain dryers were designed: the first is a commercial model (capable of drying 14 kg of açaí kernels) and the second is a compact model (capable of drying 1.0 kg of material). Due to the practicality of its use in the laboratory, the compact model was selected for manufacture. This prototype consists of: a micro motor (with adjustable torque and frequency, 40W of electrical power and bivolt 127/220VAC), which drives a rotating drum (measuring 24cm in diameter by 24cm in length) at a rotation speed of 57.6rpm, an air heating system (consisting of: air confinement chamber, thermal heating module and temperature controller). The equipment is autonomous for forestry use, with a photovoltaic electricity generation system (configuration: a 60Ah battery, a 540WP monocrystalline photovoltaic module, a 40A PWM charge regulator and a 1000W DC/AC inverter). In the laboratory experiments, 1 kg of açaí kernels were dried (for a period of two hours and forty-three minutes), after which the following fractions were obtained: 5% fiber, 1% insoluble particulate matter from the mesocarp and 63% endocarp. The compact rotary grain dryer is a versatile technology that could be used in biomaterials research in the future, contributing to the region's sustainability and macro-economy.
