Abstract
A vacuum still for the distillation of grape products has a boiler to heat grape products to a temperature at which nutriments have no or minimal damage, the vapors from the vapor space of the boiler passing through three condensers in series. A vacuum is applied through the condensers in series to the vapor space of the boiler, the concentrated grape product in the boiler being processed into a food product containing the nutriments and vitamins contained in the grape product.
Claims11
A still for processing a grape product, comprising a boiler for containing the grape product to be heated, a heater for heating the grape product in the boiler to temperature below which possible damage may occur to the nutriments in the grape product, and vacuum means to apply a reduced pressure in the boiler through a condenser system to remove the volatiles from the grape product.
A still for processing a grape product comprising a boiler to contain the grape product, heating means to heat the grape product to a temperature at which minimal harm will occur to the nutriments in the grape product, a plurality of condensers connected in series to condense the vapors from the boiler, vacuum means to supply a reduced pressure through the series of condensers to the vapor space of the boiler, and cooling means for the condensers whereby the vapor is progressively cooled as the vapor passes through the series of condensers.
