Crystallization TankFunction: Separates high-melting stearin from low-melting olein in palm oil via controlled cooling crystallization, enhancing purity and tailoring melting points for specific applications.II. Working PrincipleCrystal Melting:Heats refined palm oil to70°Cto dissolve existing crystals.Crystallization & Growth:Cools oil gradually viachilling coils(using cooling tower/chiller systems).Agitation ensures uniform crystal formation of stearin (high-melting fraction).Separation:Filters crystals using membrane filters;Olein(liquid) → Storage tanksStearin(solid) → Recovery vesselsIII. Technical FeaturesFeatureBenefitHigh-Efficiency CrystallizationChilling coils + agitation enable uniform cooling and crystal growth.Precision ControlAutomated temperature regulation (±0.5°C) optimizes crystal size/distribution.Energy-Saving DesignRecirculated cooling water/chilled brine reduces energy use by 20–30%.Integrated FunctionCompatible with filtration systems for continuous separation.IV. ApplicationsPalm Oil Fractionation:Olein: Used in frying oils, margarine.Stearin: Raw material for candles, soaps, and cocoa butter substitutes.Palm Oil Dewaxing:Removes wax crystals to improve clarity and cold stability.V. Key AdvantagesIncreases olein yield by≥15%vs. conventional methodsAchievesIV 56–59 (olein)andIV 32–35 (stearin)Reduces filtration cycle time by40%Meets ISO 22000 & HACCP standardsTechnical Specifications(Standard Unit):Capacity: 5–200 tons/batchCooling Rate: 0.1–0.5°C/minOperating Pressure: -0.05 to 0.3 MPaPower Consumption: 0.8–1.2 kW/tonEssential for producing specialty fats with customized melting profiles (MP 24°C olein; MP 50°C stearin).
