A pollution-free production device for high-quality vegetable oil and method for producing vegetable oil

Abstract

The invention discloses a pollution-free production device for high-quality vegetable oil and a method for producing vegetable oil. The pollution-free production device comprises a high-pressure tank, a pressure gauge, a motor, a stirrer and a controller, wherein the motor is fixed at the top part of a high-pressure tank cover, the stirrer is arranged in the high-pressure tank, the stirrer is fixed on an output shaft of the motor, the pressure gauge is communicated with the high-pressure tank by a pressure gauge connector, a heater is arranged at the bottom of a high-pressure tank body, the bottom of the high-pressure tank body is communicated with a main pipeline, a liquid inlet and outlet pipe, a one-way gas inlet valve, an air filter, a high-pressure pump and an air dryer are sequentially connected on the main pipeline, a liquid inlet valve is arranged on the liquid inlet and outlet pipe, and the high-pressure pump and the pressure gauge are both electrically connected with the controller. For the method, the high-quality vegetable oil pollution-free production device is adopted to extract vegetable oil from vegetable oil-rich plant materials. The pollution-free production device has simple structure and can be used conveniently; the method can be operated simply, has low production cost, and is clean and environmentally friendly; and the vegetable oil acquired by the method has high quality and is safe and healthy.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a pollution-free production device of high-quality vegetable oil and a method for producing vegetable oil. Background technique [0002] Edible oils of vegetable origin are the main source of human edible oils. There are three basic methods for producing edible oil from plant sources: one is to use physical methods to extract oil, which has a low oil yield, but there is no solvent pollution, and the quality of the oil is better; the other is to use chemical solvents such as No. 6 gasoline or benzene Extract the total oil extract from plant materials, and then use methods such as dewaxing, degreasing, decolorization, and deacidification to obtain high-quality edible oil. This method has a high oil yield, but the production process is relatively complicated, and there are solvents Residue; The third method is to extract edible oil by water enzymatic method, which is to use...

But there are solvent residues and health threats, and there are also pollution problems

In order to solve the solvent residue, some oil production enterprises use supercritical extraction method to extract edible oil. This extraction method usually uses carbon dioxide as solvent, but there is a high pressure requirement, which makes it difficult to produce on a large scale. Oils extracted with carbon dioxide also contain more triglycerides and vegetable waxes, and dewaxing and other processes are still required after extraction; in order to reduce costs, some oil companies now use 134A refrigerant (tetrafluoroethane) as a solvent for Subcritical extraction of edible oil. However, although the pressure requirement of tetrafluoroethane is lower than that of carbon dioxide, tetrafluoroethane also requires a pressure system with high sealing requirements. What is more noteworthy is that tetrafluoroethane is carcinogenic, so There are also potential health threats for edible oil production
