Resumo: | Milk is one of the main foods and possesses considerable nutritional richness. In this sense, the consumption of industrialized food products has increased significantly and with this it is important to know and improve the processes of hygiene of the industry. Clean in Place (CIP) is a useful technology for cleaning equipment and pipes because it avoids dismantling and is made up of several steps, such as cleaning with alkaline detergent, rinsing, applying acid, rinse, sanitize and rinse. The objective of this work was to evaluate the water consumption and the consequent generation of effluent in the alkaline detergent rinsing stage using constant flow and pulsed flow rates and also to propose an optimal configuration of the pulsed flow to minimize the consumption of water and effluent generated. The tests were conducted in a CIP system prototype and executed based on a central composite planning (CCP) changing the variables amplitude, period and duration of the high part. The response surface technique was used to evaluate the effects of each variable on water consumption. It was verified that there is an optimum condition for the operation of the rinse in pulsed form with amplitude 1.5 L / min, period 138 seconds and duration of the high part of 53 seconds. In addition, it has been found that the rinse with pulsed flow produces an economy of approximately 14.52% in relation to the constant flow operation. |

Nesse sentido, o consumo de produtos alimentícios industrializados tem aumentado significativamente e com isso é importante conhecer e melhorar os processos de higienização da indústria. A limpeza no local, clean in place (CIP), é uma tecnologia útil para limpeza de equipamentos e tubulações, pois evita tanto a parada da produção por longo período quanto a desmontagem dos mesmos e é composta de diversas etapas, como limpeza com detergente alcalino, enxágue, aplicação de ácido, enxágue, sanitização e enxágue. Neste trabalho foi avaliado comparativamente o consumo de água e a consequente geração de efluente na etapa de enxágue do detergente alcalino utilizando vazão constante e vazões pulsadas e ainda proposto um ajuste ótimo do valor da vazão pulsada para minimização do consumo de água e do efluente gerado. Os ensaios foram conduzidos em um protótipo de sistema CIP e executados com base em um planejamento composto central (PCC) alterando as variáveis: amplitude, período e duração da etapa de maior valor de vazão. Utilizou-se a técnica de superfície de resposta para avaliar os efeitos de cada variável sobre o consumo de água. Os resultados experimentais obtidos mostraram que existe uma condição ótima para operação do enxágue de forma pulsada com amplitude 1,5 L/min, período 138 segundos e duração da etapa de maior valor de vazão de 53 segundos. Além disso, verificou-se que o enxágue com vazão pulsada produz uma economia de aproximadamente 14,52% em relação a operação a vazão constante.Universidade Federal de Santa Maria2018-12-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/reget/article/view/3470810.5902/2236117034708Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, V. 22, 2018; e12Revista Eletrônica em Gestão, Educação e Tecnologia Ambiental; REGET, V. 22, 2018; e122236-11702236-1170reponame:Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMenghttps://periodicos.ufsm.br/reget/article/view/34708/pdfCopyright (c) 2018 Electronic Journal of Management, Education and Environmental Technology (REGET)http://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessSilva, Lucas DonizeteGedraite, Rubens2022-08-09T16:43:44Zoai:ojs.pkp.sfu.ca:article/34708Revistahttps://periodicos.ufsm.br/regetPUBhttps://periodicos.ufsm.br/reget/oaimarcelobdarosa@gmail.com||reget.ufsm@gmail.com2236-11702236-1170opendoar:2022-08-09T16:43:44Revista Eletrônica em Gestão Educação e Tecnologia Ambiental (REGET) - Universidade Federal de Santa Maria (UFSM)false |
