Secagem de café cereja descascado por ar quente e microondas

Abstract: Entre as diversas alternativas hoje praticadas para o preparo de café em nosso País, um novo método está se disseminando, principalmente entre os pequenos produtores: o da tecnologia do café cereja descascado, visando proporcionar um sistema de preparo de café de qualidade [2]. Em contraste com os bem conhecidos processos do café natural e lavado, descritos por SIVETZ & DESROSIER [10], esta técnica está baseada no despolpamento mecânico da fruta madura com o intuito de remover a maior parte da polpa mole envol… Show more

“…In the microwave heating, moisture is heated instantly inside the grain through the movement of water molecules by electromagnetic waves. In turn, in the convective drying, heat is transferred from the flowing air to the interior of the grain, which is not a fast process, as reported by Cunha et al (2003).…”

“…The advantage of the hybrid system is that the bed of coffee beans is heated by microwaves rather than drying air, generating substantial energy savings (Cunha et al, 2003). To test hybrid drying, a Borém et al (2014).…”

“…A literature review has shown that several studies have been conducted on microwave drying. The studies are related to the production of husked cherry coffee (Cunha, Canto, & Marsaioli, 2003), coconut husk (Valadez-Carmona, Cortez-García, Plazola-Jacinto, Necoechea-Mondrágon, & Ortiz-Moreno, 2016), dried carrots (Béttega et al, 2014), strawberries (Böhm, Kühnert, Rohm, & Scholze, 2006), macadamia nuts (Silva, Maximo, Marsaioli, & Silva, 2007), and granulated solids (Berteli, Nogueira, & Marsaioli, 2015). However, there is a lack of studies on the microwave drying of Araucaria seeds.…”
