Resveratrol and Grape Seed Oil Extraction Plant

Description

Resveratrol and grape seed oil extraction plant, from grape pomace. The process consists of the separation of skins and seeds of the grape, mechanical extraction of oil from seeds, and aqueous ethanol extraction of resveratrol from grape skins. The plant consists of the following sections/equipment:

1. Pomace processing plant: rotary drum separator for separating grape skins from grape seeds, cleaning equipment for grape seeds, washing equipment for grape seeds, dryer for grape seeds, silo for storage of grape seeds, mechanical press for grape seed oil, grape oil storage tank.

2.
