Description

Technical Field

[0001] The invention relates to the technical field of food engineering, in particular to coconut oil extraction equipment. Background Art

[0002] Coconut oil is a vegetable oil, but its saturated fatty acid content is as high as 80% to 90%, which is much higher than other common vegetable oils. It can be eaten, used as a skin care product, and can also be used as a chemical raw material. In terms of daily diet, coconut oil is rich in linoleic acid, palmitic acid, caprylic acid, vitamin E and other nutrients, which can replenish energy and improve metabolism. In terms of skin care, coconut oil can effectively moisturize the skin, relieve symptoms of dry skin and peeling, and can also effectively lock in skin moisture and improve skin damage when applied externally to the skin.

[0003] There are several common methods for extracting coconut oil. One is dry extraction, which is to obtain coconut oil by drying, squeezing and filtering coconut meat. This method is relatively simple to operate, but the oil yield may be low. The second is wet extraction, which is to first add water to the coconut meat and mash it into a pulp, and then centrifuge or filter to separate the oil. This method has a relatively high oil yield, but the process is relatively complicated. There is also a solvent extraction method, which uses an organic solvent to dissolve the oil in the coconut meat, and then removes the solvent by distillation and other methods to obtain coconut oil. In addition, supercritical fluid extraction is also an emerging extraction method, which uses supercritical carbon dioxide as a solvent to extract coconut oil, and has the advantages of high efficiency and environmental protection. In the prior art, wet extraction is more commonly used in industry, but the extraction efficiency of conventional equipment is low and the overall process flow is long, resulting in the high production cost of coconut oil.
