Processing method for simultaneously producing squeezed flavor oil and leaching ordinary oil

Abstract

The invention belongs to the field of edible oil processing, and particularly relates to a processing method for simultaneously producing squeezed flavor oil and leaching ordinary oil. The method particularly comprises the following steps: puffing a raw material germ flake, cooking, squeezing, and removing impurities, so as to obtain squeezed flavor oil and a raw material oil cake; mixing the squeezed raw material oil cake with the uncooked raw material germ flake; and puffing, cooling, leaching and desolventizing, so as to obtain ordinary leached oil and raw material meal, wherein the raw material germ flake is a rapeseed germ flake and / or a soybean germ flake. Through the method, the functions of producing the squeezed flavor oil and leaching the ordinary oil can be achieved by the same production line and equipment, thus equipment investment is reduced; the utilization efficiency of equipment is improved; the enterprise investment cost is lowered; and the economic benefits of enterprises are improved.

Description

technical field [0001] The invention relates to a processing method of edible oil, in particular to a processing method for simultaneously producing pressed oil and extracted oil. Background technique [0002] According to statistics, at the end of 2012, the production capacity of my country's soybean oil processing industry reached 130 million tons, but the soybean processing volume was about 60 million tons, which was less than half of the processing capacity. Therefore, how to improve the efficiency of the equipment is a question worth thinking about. The invention provides an edible processing method, which can simultaneously produce pressed flavor oil or ordinary extract oil with only one production and processing line. By adopting the method, the utilization efficiency of the equipment can be improved, the investment cost of the enterprise can be reduced, and the economic benefit of the enterprise can be improved. [0003] "Pressing" and "extraction" are the two most ...

Problems solved by technology

The "pressing method" is to extract the oil from the raw material through physical methods and mechanical extrusion. The advantage of this method is that it is natural and pollution-free, and it can keep the flavor components in the edible oil to the maximum extent, and the obtained oil has a strong flavor , suitable for use as flavor oil; however, its oil yield is low, and there will be a large amount of residual oil remaining in the raw material, which will cause huge waste if it is not used rationally; the "leaching method" uses a chemical solvent, usually n-hexane , extract the oil from the raw material, and then separate the oil from the solvent through a series of evaporation processes

This method has a high oil yield, is suitable for large-scale industrial production, and is low in cost; however, due to a series of high-temperature desolventization treatments afterwards, the flavor components in the edible oil will be lost, so it is suitable for the production of ordinary edible oil

However, there is currently no process that combines the two methods to simultaneously prepare pressed flavor oils and leached regular oils
