Diagnóstico e treinamento em sistema de refrigeração industrial de cooperativa de polpa de fruta congelada

Abstract

Cooperatives are organizations that enhance the business of family farming, but ensuring the competitiveness and survival in times of crisis depends on the efficiency and effectiveness of processes, reducing expenditures. The energy consumption in low temperature processes are pointed out as the main points for reducing operating costs. Against this background, it is proposed a diagnosis of a cooperative in cooling system for pulp processing frozen fruit, aiming to reduce the cost of electricity. Initially, the flowchart process was detailed, making up a survey of critical points for improvement. The thermal loads of the system were determined for comparison of theoretical values with actual existing facilities. Employees underwent training and a manual has been prepared. All results are reported to senior management, followed by suggestions for improvement. Positive results were obtained by training with training multipliers and a change in posture was observed. It could be observed a 50% less spend in energy consumption during 5 months for the same flux production. As conclusion, Basic Training in Good Practices of Refrigeration is indispensable in having efficacy in this process.
