Safe preservation measures many oil products, oil machinery factory house penguins preservation measures introduced about the safety of oil products mainly to introduce the four today.
Conventional methods of reservoir including airtight storage and storage at low temperature.Storage containers basically has two kinds: one kind is big oil tanks, the capacity is small (by 10 to 20 ~ 6000 t to 1000 t), set into the oil pump, oil melting steam pipe and sealing performance of tank cover, cans, metal have certain compressive strength;Another kind is oil drums (iron), useful 1.22 mm sheet made of single VAT and made from 1.5 mm double barrel, its capacity can be as big or as little as needed.
Storage product, must remove the water in the oil, impurities and all material can cause rancidity.No water, no noise, low acid oil is the most basic prerequisite for palm oil refinery plant (http://www.palmmill.com) safe storage.Add metal sting mixture (passivation), 10 ~ 15 ℃ low temperature is much use grease is one of the guarantee of safe storage.
The inhibitor method:
Application of antioxidants are added to the oil to prevent inhibitor for the oxidation method called the method.
Antioxidants used in oil, rubber, polymerizer detergent industries has a history of nearly a century.After a long period of research, antioxidant performance good already had more than 500 kinds.But because of the characteristics of the material, antioxidant performance and dissolved, dispersed, when using conditions, such as temperature, moisture and toxicity, can satisfy a certain substances (such as edible oils and fats) antioxidant is not much.
Application and edible oil antioxidants (hereinafter referred to as the "grease") began in the 30 s of the twentieth century, the discovery, the sores resin for lard has good antioxidant effect.In 1940 the United States formally batch of this resin can be used as food additive, is the earliest recognized for oil...
