USING AN EQUIPMENT WITH VIBRATING SIEVES FOR SEPARATION OF GRAPE SEEDS FROM MARC.

In the technological process for obtaining grape seeds oil, a very important stage is the separation of grape seed from pomace. Depending on the attention paid to this stage depends on the quantity and quality of grape seed oil. Therefore, INMA Bucharest has developed vibrating sieves equipment to encourage the exploitation of vegetable waste from the wine industry. In this article, the point focus is the qualitative and quantitative separation of grape seeds from the marc of three grape varieties. At the same time, we changed the way the equipment works by changing the frequency of the equipment control panel. In this article, we aim to separate the seeds from the pomace in order to extract the oil contained in them. For this, we took into account the research in the field which confirms the fact that globally grapes are the most cultivated and widespread fruits, about 7.5 million hectares with a production of approx. 78 million tonnes and most of this is used in the wine industry.
