Process method for digesting plant oil by using carbon dioxide

Abstract

The invention relates to a process method for digesting plant oil by using carbon dioxide, and aims at solving a conventional plant grease processing method and achieving the purpose that plant powder grains are separated from grease by soaking plant powder grains in carbon dioxide to rapidly separate the grease from the plant grain powder. By adopting the process method for digesting the plant oil by using the carbon dioxide, a production process of the grease is greatly simplified, residues which can affect human bodies because of chemical components are eliminated, the original juice and the original taste of the plant oil are maintained, and the product quality of the plant oil is improved. The method is safe and reliable in production, free of explosion, free of combustion and free of toxicity, the method is simple, and convenient to operate, the degreasing is rapid and thorough, the oil yield is high, the production cost is low, the production efficiency is high and pollution on grease is free, and the processing quality of the plant oil is improved.

Description

【Technical field】 [0001] The present invention relates to a process method for processing vegetable oil products of agricultural economic crops, that is to say, a process method for extracting vegetable oil from plant grains, to be precise, a process method for extracting vegetable oil with carbon dioxide. 【Background technique】 [0002] As we all know, the vegetable oil that people eat in daily life is extracted from camellia seed, rapeseed, peanut seed, soybean seed, corn seed, sunflower seed, olive fruit, etc. There are also many non-edible vegetable oils such as castor oil and tung oil that are extracted from castor beans and tung seeds. Some of the traditional extraction methods for these vegetable oils are hot pressing, that is, drying the plant seeds and frying them in a frying pan, and then putting the fried plant seeds into an oil press for pressing. Make the oil in the plant grain leak out. This traditional small workshop-style extraction method is not easy to co...

AI Technical Summary

Problems solved by technology

When the extrusion force of the press machine is small, the plant grain residue cake contains a large amount of oil, resulting in a decrease in the oil yield of the plant grain

There is also a cold process method of extracting vegetable oil with a refrigerant. This cold processing retains the nutrition in the vegetable oil, but the components of the refrigerant that are harmful to the human body remain in the vegetable oil. If the refrigerant leaks during the processing, it will easily cause combustion and explosion. and toxic gases, bringing unsafe factors to production

These traditional oil-making processes will have a certain impact on the processing quality and safe production of vegetable oil, making the quality of vegetable oil less than high-quality.
