How Wineries Use Centrifuges for Grape Processing
You obviously don’t need a centrifuge for winemaking. For nearly 10,000 years humans have been stomping grapes, mashing up fruit and honey, or spitting starchy root pulp into jars, then letting it ferment. Wine happens. That said, most commercial-scale winemakers use centrifuges. Why? Because centrifugation is a quick and effective method for separating liquids and insoluble matter without ...

Winery solid residue revalorization into oil and antioxidant with nutraceutical properties by an enzyme assisted process
ABSTRACTRevalorization of the winery industry residue, grape seed is studied for the production of an oil and defatted meal with nutraceutical properties. Conventional grape seed oil extraction process is carried out by pressing at high temperature affecting the product quality. Oil extraction by cold pressing improves product quality, but it gives a low oil yield. Oil extracted is increased at ...

Grapes Dehydration for Raisins Production in Turkey
Raisins are produced commercially by drying harvested grape berries. In order for a grape berry to dry, water inside the grape must be removed completely from the interior of the cells onto the surface of the grape where the water droplets can evaporate. However, this diffusion process is very difficult because the grape skin contains wax in its cuticle, which prevents the water from passing ...

Amelioration of the physical properties of slate processing fines using grape marc compost and vermicompost
The effect of grape marc compost and grape marc vermicompost on the soil physical characteristics of slate processing fines, a waste produced during the processing of slate blocks, has been evaluated in two short-term studies. In the first study, the slate processing fines were mixed with the composts at three rates (4, 8, and 16% dry weight, equivalent to approximately 60, 120, and 240 Mg ha–1), ...

Predicting Shiraz Yield to 95% accuracy in Barossa, Coonawarra and the Hunter Valley
Yield prediction of grapes to date has so far been anyone’s guess. In-field estimates, even on the week of picking, can have an error of up to 30% from the actual tonnage. With the variability in weather conditions causing bumper and bust yields for the past few seasons, it’s been extraordinarily difficult to give accurate estimates for winery production. To predict yield, ...
