| 摘要 |
The invention relates to a method for the industrialised production of olive oil mill by-products and to the product thus obtained. According to the invention, fresh alpeorujo (1) from the olive oil mill is subjected to a series of steps that can be used to obtain valued by-products hitherto regarded as waste. For said purpose, the alpeorujo (1) is dehydrated (4) by means of centrifugation. The solid fraction (6) obtained first is dried (9) for the subsequent separation of the pulp (12) and the stone (13), while the liquid fraction (5) is centrifuged (18) in order to separate the solids (19) and to obtain raw vegetable water (20) which, following centrifugation (21), biological treatment (25), alcoholic fermentation (26) and filtration (27), is concentrated (32) using a multi-effect vacuum evaporator, such as to produce a multi-purpose concentrate (34) and condensed water (35) which move to a column used to purify the volatile substances (36) in order to separate the alcohol (38) from the water (43) for the final purification step which is performed using respective purifying columns (39 and 45). |
