The invention relates to a
vegetable oil deodorization
system. A packing segment is arranged at the upper part of a deodorization
tower; a plate
tower segment is arranged at the lower part of the deodorization
tower; the top of an upper shell is connected with packing segment vacuum-pumping pipes; plate tower segment vacuum-pumping pipes connected to a lower shell of the deodorization tower at the upper part of the plate tower segment are respectively connected with an overall vacuum-pumping
pipe; a plurality of
oil distribution holes are distributed in a baseplates of
oil distribution disks of vacuum oil heat exchangers; the projections of all the
oil distribution holes are uniformly distributed at the peripheries of upper
pipe openings of array pipes of the corresponding heat exchangers; a plurality of sawtooth grooves are uniformly distributed in the circumferences of the upper
pipe openings of the array pipes of all the heat exchangers; a deodorization distillate capturing tower is divided into an
upper segment and a lower segment, gas phases of which are communicated; a
vitamin E capturing packing layer is arranged at the lower part of the deodorization distillate capturing tower; a
fatty acid capturing packing layer is arranged above the deodorization distillate capturing tower; the
vitamin E capturing packing layer and the
fatty acid capturing packing layer are respectively used for capturing
vitamin E and
fatty acid; a dry-type freezing condenser is formed by a plurality of primary condensers which are connected in parallel and then connected in series with secondary condensers; the arrangement spacing of
refrigerant array pipes is gradually reduced along an air feeding direction. The
vegetable oil deodorization
system has a good deodorization effect and realizes
energy conservation and environmental friendliness.
