Problems solved by technology

The neutral oil is hydrolyzed under the action of alkali, and a large amount of oil is lost; in addition, the neutral oil entrained in soapstock also causes the loss of neutral oil
Sulfuric acid acidification treatment is required to generate soapstock, which will cause a large amount of waste water and pollute the environment, and consume a lot of fuel
[0004] Physical deacidification is to inject steam into oil under high vacuum conditions to allow steam to remove unsaponifiable and odorous substances. Compared with chemical deacidification, this method does not produce soapstock and requires steam, water and power. The processing requirements are very strict, and it is not suitable for heat-sensitive cottonseed oil, and the disadvantages such as polymers and trans-acids produced by oil at high temperature, many equipments, and high energy consumption
[0005] There are many equipments for hydration degumming and thermal polymerization degumming, and a lot of chemical substances are used, resulting in serious chemical environmental pollution. At the same time, the equipment consumes a lot of energy and water.

Abstract

The invention discloses a filter material for purifying crude oil in edible vegetable oil production by taking attapulgite as a carrier. The filter material comprises the following ingredients in percentage by mass: 54% of attapulgite clay, 15% of polyethylene glycol 2M, 9% of carbon black, 14% of calcium chloride and 8% of deal powder. The filter material granulates are large in specific surface area, and the filter material is good in adsorbability, is high in purification capability, can thoroughly treat crude oil almost without pollution, not only can achieve deacidifying, deguming, decoloring and deodorizing effects effectively, but also can remove heavy metal in vegetable oil, does not contain harmful substances to human bodies, conforms to the National food safety standard-standards for uses of food additives (GB2760-2011), and also can be recycled, so that the using expense is lowered.

Description

technical field [0001] The invention relates to a filter material, in particular to a filter material with attapulgite as a carrier for crude oil purification in edible vegetable oil production. Background technique [0002] In the traditional vegetable oil production process, degumming, deacidification, decolorization and deodorization are used to remove non-glyceride components in crude oil. Vegetable oil deacidification methods usually refer to deacidification methods used in industrial production, including chemical deacidification, physical refining (or deacidification) and mixed oil refining (or deacidification) methods. [0003] Chemical deacidification, also known as alkali refining deacidification, is the most commonly used method in industry. Usually, lye is added to the degummed oil to make the lye react with free fatty acids and precipitate in the form of soapstock. Some impurities are also absorbed by soapstock. The feet were removed by centrifugation. Che...
