Authoritative Oil Extraction Methods Introduction

Oil Extraction Process is one important processing during making oil process. There are many kinds of OIL EXTRACTION METHODS in actual applications. Wintone shares oil extraction methods with more than 20 years oil mill machinery experience.
CO2 Extracted:
CO2 extracted oils are extracted using fluid carbon dioxide as the solvent. Carbon dioxide is converted to liquid using high pressure making it a safe and effective solvent that allows all the desirable active constituents of a plant to be collected without the risk of heat degradation. Once the extraction is complete, the pressure is released allowing the carbon dioxide to return to its natural gaseous state, leaving behind only the extracted essence of the plant. CO2 extracted oils are the closest representation of the natural plant ever achieved. CO2 total extracts include the volatile components as well as the heavier, waxy components that give plants their color, and are therefore thick and waxy in consistency.
Cold Pressed or Cold Expeller Pressed:
Cold pressed oils, also known as cold expeller pressed oils, have been mechanically pressed from the fatty portions of the botanical while ensuring that the maximum temperature (caused by friction) does not exceed 120 degrees.
Expeller Pressed:
Expeller pressed oils are mechanically pressed from the botanical material at high pressure to obtain maximum yield. Not all expeller pressed oils are cold pressed as high pressure extraction can cause temperatures to rise above 120 degrees. Only if temperature is monitored and kept under 120 degrees, can the oil be called cold pressed. Otherwise it is simply called expeller pressed. FromNatureWithLove.com always strives to supply cold pressed oils whenever possible, however, some oils cannot be cold pressed.
Solvent Extracted:
Sometimes it is necessary to use a solvent in order to extract the oil from certain seeds, nuts or kernels in order to make the extraction cost effective. Once the oil has been obtained, the...
