[EN] Atmospheric freeze drying (AFD) yields products of a similar quality to the conventional vacuum freeze-drying technique, but reduces the operating cost. However, it involves very low drying rates. The sample ...

[EN] In this work the influence of some process variable on drying rate of henna leaves was studied. For this reason, henna leaves were dried (1 m/s) with and without ultrasound application at three temperatures, 40, 50 ...

[EN] Sulphate attack is the most-known expansive reaction that affects to concrete durability. The most important standards related to sulphate attack try to control the expansion of elements made with concrete restricting ...

[EN] The research presented was conducted to quantify the effects of butterfly and gate valves located upstream water meters with diameters larger than 50 mm. Errors caused by these valves can have an enormous financial ...

[EN] Atmosphere freeze drying (AFD) is a slow process that provides high quality dried products. Power ultrasound (US) can be used to intensify this process and the sample surface is another important factor to be into ...

[EN] Power ultrasound is being used as a novel technique for process intensification. In this study, the feasibility of using power ultrasound to improve the phenolic extraction from olive leaves was approached taking both ...

[ES] La creciente preocupación de los consumidores por reducir la cantidad de NaCl en la dieta y la variabilidad en el contenido final en sal en los productos crudo-curados está impulsando a las empresas cárnicas a desarrollar ...

[EN] Demineralization is a process of loss of minerals in the dental hard tissue that affects seriously the health of the patients, as it diminishes the tooth resistance, generating chewing problems by altering the occlusal ...
