2 The first Semi-Continuous Deodorizing System was installed by Votator in Since then more than 200 Votator plants have been placed in operation around the world. Today these plants, ranging in capacities of 2,500 pounds-per-hour to 30,000 pph, process in excess of 20 billion pounds of edible fatty oils every year. Votator Deodorizers, both the semicontinuous and Econoflow* continuous systems, process the fullvariety of vegetable oils, meat fats, and marine oils; included are soybean oil, cottonseed oil, peanut oil, safflower oil, corn oil, rapeseed oil, lard and tallow. Heat recovery interchange and distillate recovery are standard with these systems. Also available are equipment options for the addition of anti-oxidants and emulsifiers, as well as equipment adaptations for physical refining. Systems that match your stock change frequency Votator Semi-Contin uous Deodorizing Systems are unsurpassed in stock change flexibility. Users report repeated changeover with minimal production interruptions. For operations with few feedstock changes, Econoflow Deodorizing Systems offer the advantages of both continuous feed/discharge and semicontinuous deodorizing; these include high yield with improved heat recovery economies and controlled residence times to meet your exact deodorizing specif ications. Both the semi-continuous and continuousystems feature anti-splashreflux baffling and automatic, programmable control systems to assure first quality end product. Benefits of VOTATOR Deodorizer Systems Energy savings - Both semi-continuous and continuousystems are designed for high energy efficiency. Complete deodorizing - inefficient backmixing and short-circuiting is eliminated by the plugjlow operating principle; each batch of oil is retained in each tray for the prescribed time so that all of the oil is subjected to complete deodorizing conditions. Top-quality end product - a unique baffle design in each tray provides an optimum steam-oil interface; excessive entrainment of neutral oil is eliminated. Maximumstock changeflexibility \/ - change from one feedstock another with semi-continuous systems can be effected with negligible intermixing and without significant loss in production time. With continuous systems, changeover time is typically 30 minutes. No leakage of air into oil - the traywithin-shell design eliminates air contamination of the oil being processed. No retlux - prevented by the umbrella-over{ray design. Ease of operation - all process variables and interlocks are automatically controlled to assure proper operating conditions at all times. v *Econoflow contains Votator desrgn concepts and is licensed f rom Srmon-Rosedowns, Ltd.

3 T he VOTAT OR Semi-Continuous Deodorizer (flow diagram 1) consists essentially of five stainlessteel trays supported one above the other inside a carbon or stainlessteel vessel. The trays contain the necessary coils for heat interchange, final heating and cooling of the feedstock, stripping and agitating steam distribution, and deodorization. The deodorizer vessel is maintained at a low absolute pressure, and steam is continuously injected into each tray at a specified flow rate. During each operating cycle, a batch of oil is pumped from the supply source to the measuring tank. This batch of oil flows by gravity in a controlled sequence from tray to tray. In the top tray, oil is initially deaerated and preheated by a thermo-syphon heat interchange loop. The second tray heats the oil to deodorization temperature by utilizing a high temperature heat source. Fatty acids and impurities are removed from the oil by violent contact with steam in the third or deodorization tray. Heat energy is recovered from the hot oil in the fourth tray for use in preheating the feedstock via the Thermo-Syphon Heat Interchange Loop. The final tray cools the oil prior to discharge from the deodorizer for filtration and storage. High Temperature Heat Source Heal Recovery Interchanger High Temperature Heat Source Heat Interchange Loop Measuring Tank Shell Drain Tank Diagram 1 For plant operations with infrequent stock changes, the Econoflow Deodorizing System (flow diagram 2) provides an attractive alternative to the standard Semi- Continuous Deodorizer. The Econoflow offers significant savings in operating costs by combining continuous feed/discharge with highly efficient external heat exchange equrpment that recovers up to B0 percent of the process heat input. The Continuous Deodorizer uses the same deodorization contactor as the semicontinuous model for top-quality deodorized oil. Continuous deodorizing plants are equipped with microprocessor based PLC systems for improved reliability, ease of modification, and flexibility of integration into existing plant control schemes.

4 The patented Votator deodorizing tray was developed to provide a more effective means for the intimate contact of stripping steam and edible oil. The steam distributor, baffle arrangement, and umbrella combine to provide the mixing and volatile dispersion of the gas/liquid mixture essential for effective deodorization. Semi-Continuous Deodorizers are usually designed for 15 minutes total deodorizing time at temperatures up to 525oE 3 MM Hg. absolute pressure. The operating conditions can be varied depending upon the feedstock and customerequirements. Ancillary Equipment Included with the basic deodorizing components are. Process instrumentation, control packages, and design engineering o Vacuum system, consisting of multi-stagejector, or combi nation ejector/mechanical pump designs o Dowtherm heating system, consisting of vaporizer, storage tank, transfer pump, vent condenser and ejector. Auxiliary equipment, consisting of charge pump, measuring tank, shell drain tank, discharge pump, filter and piping components o Distillate recovery system, consisting of scrub cooler vessel, circulating pump, instrumentation, and piping components

7 Votator semi-contin uous deodorizing plants are equipped with heat interchange facilities for heat recovery and resultant steam savings. The top and fourth trays contain interconnecting coils filled with distilled water;the coils utilize the closed loop thermo-syphon principle to transfer heat from the finished oil into the cold feedstock. ln operation, the fatty oil feedstock is automatically admitted to the top tray. Steam generated in the tray below the deodorizing tray rises to the top tray coils and heats the feedstock; the condensate flows back to the heat interchange tray. lt provides efficient heat recovery and takes maximum advantage of the quality protection afforded by the high temperature deodorization going on within the confines of the low-pressure vessel.
