Problems solved by technology

[0008] Existing methods for removing plasticizers are few, single means, large equipment investment, high cost, and serious equipment loss
Moreover, the peroxide value and acid value of the obtained oil are high, and some even have solvent residues, resulting in a decline in the quality of the oil

Embodiment 1

[0038] Turn on the equipment for removing plasticizers in Ω-3 and Ω-6 oils by low-temperature molecular distillation, and adjust the process parameters of the equipment, including flow meter 135L / H, primary distiller temperature 175°C, rectifier temperature 180°C, primary distillation The vacuum degree of the rectifier is ≤10.0pa, the vacuum degree of the rectifier is ≤5.0pa, and the cooling water temperature is 25°C; when the equipment execution parameters reach the set value, the feeding is carried out. The pumpkin seed oil is sent to the flowmeter by the feed metering pump, and then sent to the energy-saving heat exchanger after precise metering, and then sent to the pretreatment evaporator, and then sent to the primary still for distillation through the intermediate pump 1, and the primary still distills about 70% Pollutants such as plasticizers and solvent residues are distilled out by the discharge pump 1, and the remaining oil is sent to the rectifier by the intermediate...

Abstract

The invention provides a preparation method of low-peroxide value and zero-plasticizer omega-3 and omega-6 series greases. The preparation method simultaneously reduces the peroxide value and the acidvalue of the omega-3 and omega-6 series greases (such as Oenothera biennis oil, perilla seed oil, pumpkin seed oil, linseed oil, hickory nut oil, borage oil and grape seed oil). A double-distillationtechnology is adopted to make the removal rate of a plasticizer reach 100%. The method adopts a physical separation technology and uses the characteristics of low-temperature molecular distillation,so the acid value and the peroxide value are effectively reduced, the plasticizer and the residual solvent are completely removed, natural nutritional components in materials are effectively retained,and the nutritional values of alpha-linolenic acid, gamma-linolenic acid and natural antioxidant components VE and sterols are effectively maintained. The method has the advantages of energy consumption saving, simplicity, effectiveness, great reduction of the production cost, and obtaining of high-quality food grade greases.

Description

technical field [0001] The invention relates to the technical field of plasticizer removal, in particular to a preparation method of omega-3 and omega-6 series oils with low peroxide value and zero plasticizers. Background technique [0002] Phthalic acid ester plasticizers (Phthalic Acid Esters, PAEs) are a kind of environmental hormone substances, PAEs are generally colorless and transparent oily viscous liquids, easily soluble in organic solvents, and their synthesis is usually from naphthalene and o- Toluene is catalyzed to oxidize to generate phthalic anhydride, which is then obtained by esterifying phthalic anhydride with various alcohols. Although PAEs have no acute toxicity to the human body, the long-term accumulation of chronic toxicity in the human body is especially harmful to reproductive development. Toxicity cannot be ignored. Studies have found that o-benzene plasticizers can cause abnormal functions of the vas deferens, seminal vesicles and prostate glands ...
