OTIMIZAÇÃO DE UMA MÁQUINA PARA PRÉ-LIMPEZA DE CAFÉ EM GRÃOS RECOLHIDO DO CHÃO PELO PROCESSO DE VARRIÇÃO

Abstract

Coffee processing involves several machines and equipment, considering that this product is produced on a large scale in Brazil, and is concentrated in larger quantities in the states of Minas Gerais and Espírito Santo. Soon after its production it is important that the coffee is well stored for commercialization, it is also necessary to perform a processing of the product and in this process can occur losses that fall to the ground and the accumulation in machine corners, therefore it is necessary to collect this coffee making An on-site sweeping operation is then collected along with coffee impurities and dust from the floor and the product itself. This step can be called precleaning, which is of paramount importance for the set of machines to be fully operational, thus avoiding reworking the beneficiation. Maintaining the workplace of the cleanest and healthiest operators ensures the quality of the coffee. Given the above, the following question arises: How to ensure the cleaning of sweeping coffee that will later benefit from using a pre-cleaning machine? To answer this question, a field study will be presented on a machine designed to pre-clean the coffee beans collected from the ground. This study aims to present a machine for pre-cleaning sweeping coffee, used to optimize the cleaning process of the places and also to facilitate their processing. This machine is located in a Coffee Growers Cooperative located in the city of Varginha, Minas Gerais.
