Grape pomace drying stabilises the skins, seeds and stems left after pressing at a winery or grape juice plant. Because seeds, skins and stalks separate cleanly once dry, the material can be split into grapeseed oil feedstock, polyphenol-rich skin powder and fuel. Wineries dry pomace to escape seasonal disposal peaks and create saleable fractions.
To dry grape pomace, GEM recommends the Mesh Belt Dryer (Meshotherm) and Band Dryer (Beltotherm). Typical moisture is 55–70% in the feed and 8–10% after drying. Rotary Dryer is used when the feed or site calls for it. Every project starts with a pilot trial on your own sample.
Grape pomace is loose and porous, so a Meshotherm mesh belt pushes air through the bed economically; a Beltotherm band is chosen when skin powder must stay food-grade. A rotary dryer handles destemmed pomace bound for fuel or feed where colour does not matter.
| Typical feed moisture | 55–70% |
| Typical target moisture | 8–10% |
| Recommended dryer | Mesh Belt Dryer (Meshotherm), Band Dryer (Beltotherm) |
| Alternatives | Rotary Dryer |
| Application area | Pomace, Pulp & By-products |
| Industries | Food & Beverage, Animal Feed, Breweries & Distilleries |
Dried pomace can be stored and sold across the year instead of piling up during vintage. Seed, skin and stalk fractions each command different buyers, and lower water content cuts transport and spreading costs sharply.
Plants searching for a grape pomace dryer or comparing a grape marc drying usually need three answers: which dryer fits, what it costs to run, and how fast it pays back. For Grape Pomace, we start from your throughput, current moisture (typically 55–70%) and the target (8–10%), trial a sample on the Mesh Belt Dryer, and return a sized recommendation with a budget quotation for your food and animal feed operation.
