How is lard oil extracted and refined?

Components in the oil other than triglycerides are called impurities.
The function of lard refining equipment is to remove impurities in lard, retain the biological characteristics of oil, and retain or extract useful substances. In fact, refining equipment does not remove all impurities, but selectively removes them.

According to the composition and properties of impurities in lard, it can be divided into three categories:
(1) Insoluble solid impurities, such as sediment, cake powder, fiber, clay, catalyst, etc.
(2) Colloidal impurities, such as free fatty acids, sterols, vitamin E, pigments, vitamins, gossypol, etc.
(3) Volatile impurities, such as water, alcohols, hydrocarbon solvents, odorous substances, etc.
Most impurities are detrimental to the quality and storage safety of oils.

For example, water not only affects the transparency of oils, but also promotes the hydrolysis and rancidity of oils; free fatty acids affect the flavor and promote deterioration; phospholipids can make oils cloudy and produce Black precipitation, foaming, bitter taste, etc.

Various pigments directly affect the color of the oil, and also promote the rancidity of the oil; the presence of colloids, sulfur- and phosphorus-containing compounds, soapstock, and heavy metal salts. , which brings difficulties to subsequent processes such as stripping and deacidification.

The main process of lard refining equipment

(1) Lard degumming: remove phospholipids, mucus, resins, proteins, sugars, trace metals, etc. from crude oil. Generally, hydration method and acid refining method are used.
(2) Deacidification of lard: remove free fatty acids, acid pigments, sulfides, insoluble impurities and trace metals in oil by neutralization with food-grade lye.
(3) Wash lard: wash away the soapstock and water-soluble impurities remaining in the oil during the deacidification process.
(4) Dehydration of lard: remove the moisture in the refined oil by heating and vacuum drying.
(5) Decolorization of lard: Use clay, aluminum silicate, activated carbon and other adsorbents to remove various pigments, colloids, oxides, etc. in the oil.
(6) Lard deodorization: The principle of vacuum stripping is adopted to remove low-molecular odor substances, free fatty acids, monoglycerides, diglycerides, sulfides, thermal decomposition products of pigments, etc.

How much is a set of lard refining equipment?

A set of small lard oil refining equipment costs tens of thousands of yuan, some hundreds of thousands of yuan, and some hundreds of thousands of yuan. It mainly depends on how much oil you produce and how much oil you process. Because the output determines the specifications of the refining equipment, the higher the output, the higher the price; the degree of refining determines which process links the refining equipment includes, such as the production of general edible oil, deacidification, degreasing, filtration, etc. For example, the traditional process of producing ordinary edible oil includes degumming, deacidification, decolorization, deodorization, etc. , but if the primary edible oil often needs to be dewaxed, the cost of edible oil refining equipment will be higher. In addition, the material (carbon steel, stainless steel) and quality of refining equipment are also factors that affect the price of refining equipment. The price of Benteng company lard refining equipment ranges from $10000 to $50000.
