This study was designed to measure the sound output of four commonly used brands of forced-air dryers used by dog groomers in the United States. Many dog groomers have questions about the effect of this exposure on their hearing, as well as on the hearing of the dogs that are being groomed. Readings taken from each dryer at 1 meter (the likely distance of the dryer from the groomer and the dog)...

Pepsin merupakan enzim proteolitik yang aktif dalam kondisi asam. Selama ini pepsin dihasilkan dari lambung babi dan sapi. Bahan baku alternatif penghasil adalah ikan tuna sirip kuning. Enzim bentuk kering (powder) akan lebih mudah penyimpanan bersifat stabil. Tujuan penelitian menganalisis karakteristik kuning pengaruh metode pengeringan terhadap tersebut. pepsinpepsin. Metode digunakan yaitu ...

This paper presents a mathematical model of the heat and mass transfer processes for rotary-spray honey dehydrator with pump closed air circuit. An analytical calculation model, based on energy balance equations pump, was used to transient dehydration process in dehydrator. The presented article includes different approach modelling both dryer assisting drying process. novel quality this study ...

Cereal Chem. 83(5):565-568 Traditionally, zein is isolated and recovered from corn gluten meal (GCM) using aqueous alcohol as the solvent. Recovery of zein from this solvent is inconvenient and costly. Zein is insoluble in 100% ethanol at room temperature, but it is soluble at 120°C in ethanol. Absolute ethanol effectively extracted zein from CGM, distillers dried grains (DDG), and ground corn....

Spray dryers are of considerable importance in many industrial drying operations, yet their modelling has been relatively neglected. Here we present a summary of many years work performed at Sydney University investigating the fundamental flow behaviour in dryers and their modelling using a commercial CFD code. The key point to emerge is the need to perform three dimensional, transient calculat...
