Multi stage safe dry condensing

A deodorizing system for deodorizing an edible oil or fat provided in a deodorizer, comprising:

• the deodorizer arranged with a scrubber for stripping substances from the edible oil or fat with a stripping medium at a temperature of 160 degrees C. or more at a pressure of less than 5 mbar to produce a deodorized and scrubbed stripping medium having a first pressure;
• a dry condensing system receiving the deodorized and scrubbed stripping medium from the deodorizer at the first pressure as input to a holder associated therewith, the dry condensing system including:
• a first volume reduction unit including a first heat transfer fluid loop having the holder for directly receiving the deodorized and scrubbed stripping medium at the first pressure from the deodorizer via a connection pipe and for reducing volume of the deodorized and scrubbed stripping medium via desubliming or condensing at a first temperature, and a first pressurizing system arranged for increasing pressure of said desublimed or condensed stripping medium to a first intermediate pressure to produce a first pressurized product that is directly supplied via a first pipe to a second heat transfer fluid loop;
• a second volume reduction unit including the second heat transfer fluid loop for reducing volume of the first pressurized product via desubliming or condensing at a second temperature, and a second pressurizing system arranged for increasing the first intermediate pressure of the first pressurized product to a second intermediate pressure to produce a second pressurized product that is directly supplied via a second pipe to a third heat transfer fluid loop;
• and
• a third volume reduction unit including the third heat transfer fluid loop for reducing volume of the second pressurized product via desubliming or condensing at a third temperature, and a third pressurizing system arranged for increasing the second intermediate pressure to atmospheric pressure to produce a discharged product.
