Claims (8)

ISRAEL
1. A process for the concentration of volatiles bearing products by a low temperature, short time, multi-effect evaporation method, with a forward feed of the product and vapour so that at least from a given 3tage of evaporation, each subsequent stage of evaporation is carried out at a lower temperature, in which the volatile constituents, removed with the vapour from one or more effects and subsequently condensed and recovered, are combined with the partially concentrated product before a final stage or stages of evaporation at a temperature lower than that at which they were originally distilled off whereby a more highly volatile fraction is again removed with the vapour in the said final stage or stages of evaporation.
2. '2*. A process as claimed in claim 1 , in which the f rst evaporation .Itage of the product is at a lower temperature than the first effect.
3. A process as claimed in claim 2, in which the first evaporation stage is in the second effect. 1
4. . A process, as claimed in claim 1, 2 or 3» in which the :£»¾9«k*»iWr©n takes place immediately prior to the final evaporation stage.
5. A process as claimed in any of claims 1 to , in which the product is fruit juice.
6. A process as claimed in claim 5, in which the product is a citrus fruit juice.
7. · .'Apparatus- ; for carrying. out a process as claimed in any of the proceding claims, comprising a multi-effect evaporator with forward feed of the product, a recovery stage for condensing and recovering volatile constituents from the vapour from at least an effect, and a recombining stage upstream of a final stage or stages of evaporation in which the recovered volatiles may "be mixed with the partial concentrate.
8. A process for the concentration of volatiles-bearing products, such as fruit juice, substantially as hereinbefore described with reference to the accompanying drawing. '9*· 'Apparatus for the concentration of volatiles-bearing products substantially as hereinbefore described v/ith reference to the accompanying drawing.
