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-hex

Embodiment 1

[0024] Under the conditions of 110°C and 12MPa, expand the rapeseed embryo flakes for 0.5min, then steam and fry the expanded rapeseed material at 115°C for 0.2h, and then press at 126°C for 10min to obtain pressed flavor rapeseed Crude oil (impurity 0.4%) and rapeseed oil cake containing 35.8% oil; then, the obtained rapeseed oil cake is entered into an extruder and mixed with some unsteamed rapeseed embryo flakes, then cooled to 55°C after puffing, Leaching by organic solvent, the leaching conditions are: temperature 50°C, time 40min, solvent ratio 0.8, and finally desolvation: the soybean meal discharge temperature (DT103°C, DC36°C), precipitating pressure (DT: vacuum degree 18mba, DC: Pressure 5.3KPa)), mixed oil precipitating temperature (first steaming oil temperature 56°C, second steaming oil temperature 100°C, stripping oil temperature 100°C), to obtain leached common rapeseed crude oil (residual solvent 60ppm) and rapeseed Seed meal (330ppm residual solvent, 0.7% oil,...

Embodiment 2

[0026] Under the conditions of 118°C and 16MPa, expand the rapeseed embryo flakes for 1min, steam and fry the expanded rapeseed material at 150°C for 0.5h, then press at 160°C for 5min, and obtain pressed flavor rapeseed crude oil after removing impurities (impurity 0.3%) and rapeseed oil cake containing 28.6% oil; then the obtained rapeseed oil cake enters the puffing machine and mixes with part of the rapeseed germ slices that have not been steamed and fried, and then it is puffed and cooled to 58 ° C, passed through an organic solvent Leaching, the leaching conditions are: temperature 58°C, time 60min, solvent ratio 1.0, and finally desolvation: wherein rapeseed meal discharge temperature (DT100°C, DC40°C), precipitating pressure (DT: vacuum degree 20mba, DC: pressure 4.8 KPa), mixed oil precipitation temperature (60 ℃ of first steaming oil temperature, 105 ℃ of second steaming oil temperature, 105 ℃ of stripping oil temperature), obtain leaching common rapeseed crude oil (4...

Embodiment 3

[0028] Under the conditions of 110°C and 12MPa, after puffing the soybean germ flakes for 0.5min, steam the puffed soybean material at 116°C for 0.3h, and then press it at 126°C for 10min, and get pressed flavor soybean oil (impurity 0.5% ) and soybean oil cake containing 8.2% oil; then the obtained soybean oil cake is put into an extruder and mixed with some soybean germ flakes that have not been steamed and fried, then expanded and cooled to 55°C, and leached by an organic solvent. The leaching conditions are: The temperature is 50°C, the time is 40min, the solvent ratio is 0.8, and finally the precipitation is carried out: the soybean meal discharge temperature (DT106°C, DC36°C), the precipitation pressure (DT: vacuum degree 18mba, DC: pressure 5.5KPa), mixed oil precipitation temperature (first steaming oil temperature 55°C, second steaming oil temperature 102°C, stripping oil temperature 102°C), to obtain leached common soybean crude oil (residual solvent 55ppm) and soybea...

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 ...
