“…It also helps in the spray drying of food (with suspensions of water and gelatinized native corn starch or native waxy corn starch, Schröder et al, 2011) and pharmaceutical and consumer products (PEO solutions (Broniarz-Press et al, 2010) such as water-oil emulsions (Broniarz-Press et al, 2009;Schröder et al, 2012), black liquor (Risberg and Marklund, 2009), and liquids for fluid catalytic cracking (Jolodar et al, 2005).…”

“…Dele dependem o potencial de deriva, a perda por escorrimento e a cobertura do alvo. Trata-se de um processo complexo, influenciado por diversos fatores, como o tipo de equipamento de pulverização empregado e as propriedades físico-químicas da calda (Cunha et al, 2003;Broniarz-Press et al, 2009). …”

RESUMO -A eficácia de tratamentos fitossanitários depende das características físico-químicas das caldas de pulverização. Dessa forma, o presente trabalho teve como objetivo avaliar o efeito da temperatura da calda e da adição de adjuvantes de uso agrícola nas características físico-químicas de soluções aquosas para aplicação de agrotóxicos. Foram avaliados potencial hidrogeniônico, condutividade elétrica, densidade, viscosidade dinâmica, tensão superficial e estabilidade de soluções aquosas contendo quatro adjuvantes comerciais de uso agrícola, além de uma amostra com apenas água, submetidas a temperaturas de 5 o C, 15 o C e 25 o C. Foi utilizado delineamento inteiramente casualizado, com quatro repetições, em fatorial 5 x 3. De acordo com os resultados, pôde-se concluir que a alteração da temperatura da calda influenciou as características físico-químicas de maneira diferenciada para cada adjuvante, o que demonstra a complexidade do estudo dessa relação e a impossibilidade de fazer generalizações. O efeito dos adjuvantes nas caracterísiticas físico-químicas das soluções aquosas mostrou-se dependente de sua composição química e formulação. A temperatura influenciou a viscosidade com maior intensidade, enquanto a tensão superficial foi a característica físico-química mais sensível ao uso de adjuvante.Palavras-chave: aditivos de calda, agroquímicos, surfatantes, tecnologia de aplicação.ABSTRACT -Pesticide application efficiency is dependent upon the physical-chemical characteristics of the spray aqueous solution. Thus, this study evaluated adjuvant addition and temperature effect on the physical-chemical characteristics of pesticide spray aqueous solutions. Hydrogenionic potential, electrical conductivity, density, dynamic viscosity, surface tension and stability of aqueous solution with four commercial adjuvants were evaluated, besides water alone. A randomized design with four replications was used, in a factorial scheme (5 x 3). According to the results, it could be concluded that the temperature effect on the physical-chemical characteristics was different for each adjuvant, showing that no simple or linear relationship could be observed. The adjuvant effect on the physicalchemical characteristics of aqueous solutions was based on their chemical properties and formulation. Temperature affected viscosity with more intensity, while surface tension was the most sensitive characteristic of adjuvant addition.

“…Therefore, for understanding of spray-chilling or drying, atomization of emulsion has to be significantly studied in first place (Dubey et al, 2010(Dubey et al, , 2011bDumouchel, 2008;Tratnig et al, 2009;Walzel, 2010). Some authors (Bolszo et al, 2010;Broniarz-Press et al, 2009;Dubey et al, 2011b;Jayasundera et al, 2009) studied spraying of emulsion, where they investigated the influences of process conditions and viscosity of emulsion on the spray droplets as well as the spraying impact on the microstructure of emulsion. Previously we have experienced on prilling process (spray + chilling) for the production of powder out of simple and double emulsions (Dubey et al, 2010(Dubey et al, , 2011a.…”
