Embodiment 1

[0016] according to figure 1 As shown, the used oil storage tank and temporary storage tank are 200 tons and 100 tons, respectively, and can withstand positive pressure of 0.1Kg / cm 2 and 0.05Kg / cm 2 , can withstand negative pressure of 0.03Kg / cm 2 and 0.02Kg / cm 2 , the initial relief pressure set by the breathing valve is 0.0014kg / cm 2 , the starting suction pressure is 0.0014kg / cm 2 . The flow rate is 16m 3 / hr. From the self-filling nitrogen oil storage tank, use a pump to pump 50T sunflower seed primary oil into a temporary storage tank filled with nitrogen. After being filtered by a filter with a pore size of 5 μm, it is pumped into a high-level tank filled with nitrogen; the 5L oil bottle enters the canning system after being blown out of impurities, and is quantitatively filled by an automatic canning machine before entering the nitrogen filling system; Taken by machine, nitrogen with a purity of 99.9% is filled into the quantitatively filled oil bottle through t...

Embodiment 2

[0018] according to figure 1 As shown, the used oil storage tank and temporary storage tank are 200 tons and 100 tons, respectively, and can withstand positive pressure of 0.1Kg / cm 2 and 0.05Kg / cm 2 , can withstand negative pressure of 0.03Kg / cm 2 and 0.02Kg / cm 2 , the initial relief pressure set by the breathing valve is 0.0014kg / cm 2 , the starting suction pressure is 0.0014kg / cm 2 . The flow rate is 16m 3 / hr. Pump 50T canola oil from the nitrogen-filled oil storage tank into a temporary storage tank filled with nitrogen. After being filtered by a filter with a pore size of 5 μm, it is pumped into a high-level tank filled with nitrogen; the 2.5L oil bottle enters the canning system after being blown out of impurities, and enters the nitrogen filling system after being quantitatively filled by an automatic canning machine; It is produced by a nitrogen machine, and the nitrogen gas with a purity of 99.9% is filled into the quantitatively filled oil bottle through the ...

Embodiment 3

[0020] according to figure 1 As shown, the used oil storage tank and temporary storage tank are 200 tons and 100 tons, respectively, and can withstand positive pressure of 0.1Kg / cm 2 and 0.05Kg / cm 2 , can withstand negative pressure of 0.03Kg / cm 2 and 0.02Kg / cm 2 , the initial relief pressure set by the breathing valve is 0.0014kg / cm 2 , the starting suction pressure is 0.0014kg / cm 2 . The flow rate is 16m 3 / hr. From the self-filling nitrogen oil storage tank, use a pump to pump 50T sunflower seed primary oil into a temporary storage tank filled with nitrogen. After being filtered by a filter with a pore size of 5 μm, it is pumped into a high-level tank filled with nitrogen; the 1.8L oil bottle enters the canning system after being blown out of impurities, and is quantitatively filled by an automatic canning machine before entering the nitrogen filling system; It is produced by a nitrogen machine, and the nitrogen gas with a purity of 99.9% is filled into the quantita...

Abstract

The invention relates to a method for preserving edible oil by charging nitrogen. After the edible oil is filled in a tank, nitrogen is charged into a bottle to lead the air in the bottle and the oxygen in the edible oil to be replaced and lead the residual oxygen in the head space of the bottle to be less than 3 percent and then a pressure pad is sealed, thus leading the residual oxygen of the edible oil in the bottle to be very low and the edible oil has no oxygen source that can supply reaction on one hand; and on the other hand, the nitrogen in the head space of the bottle forms a nitrogen sealing which obstructs the oxygen to be contacted with the edible oil, thus achieving the effects of protecting the edible oil and preventing the edible oil from oxygenation; simultaneously, the invention can avoid the hidden troubles to the health of the human body caused by using artificial antioxidant.

Description

technical field [0001] The invention relates to a method for preserving the freshness of edible oil, in particular to a method for preserving the freshness of edible oil by filling nitrogen. Background technique [0002] At present, the method to prevent the oxidation of edible oil at home and abroad is mainly to add some antioxidants to achieve the purpose of preventing the oxidation of edible oil. The antioxidants usually added are BHA (tert-butyl hydroxyanisole), BHT (di-tert-butyl hydroxytoluene), TBHQ (tert-butyl hydroquinone), natural vitamin E, ascorbyl palmitate, etc., the most commonly used antioxidant in edible oils is TBHQ. The process is to add one or more of the above-mentioned antioxidants into the edible oil in a certain proportion, fully mix and stir, and then fill and pack the edible oil into a small package. Since most of these antioxidants are artificially synthesized, there is a certain degree of potential safety hazard. TBHQ has the possibility of muta...
