Abstract

The invention provides an improved rapeseed oil ancient-method squeezing process which comprises the following steps: step 1, stir-frying: putting rapeseeds into a rotary drum baking and stir-frying machine, stir-frying the rapeseeds with firewood, stir-frying the rapeseeds until hulls and kernels of the rapeseeds can be completely separated by sampling and crushing and the kernels are golden yellow, and pouring out the rapeseeds; step 2, oil pressing: pouring the fried rapeseeds into a rapeseed oil press for oil pressing to obtain crude oil; step 3, filtering, adding 50g of saline water intoevery 5 kg of the crude oil, wherein the temperature of the saline water is 85-95 DEG C, and the concentration of the saline water is 0.5-1%, pouring the crude oil mixed with the saline water into a rapeseed oil cleaning device for cleaning and filtering, removing erucic acid and precipitate; and step 4, refining, namely adding the filtered crude oil into rapeseed oil refining equipment, dephosphorizing, decolorizing and distilling to obtain the finished rapeseed oil. The rapeseeds are stir-fried with the firewood, the fragrance of the rapeseed oil squeezed by an ancient method is kept, and the rotary drum baking and stir-frying machine is improved to guarantee the stir-frying effect; and the saline water is added to remove the erucic acid during filtering.

Description

technical field [0001] The invention belongs to the technical field of rapeseed oil preparation technology, and in particular relates to an improved ancient extraction process of rapeseed oil. Background technique [0002] Rapeseed oil is one of the main edible oils in our country. There are usually some problems that need to be solved when processing rapeseed oil with rapeseed: one is the problem that the finished oil is not fragrant enough, frying rapeseed is the way to solve this problem One, however, how to set up the frying process, how to control the frying process, and how to judge the standard of frying maturity will all affect the quality of the refined oil; the second is how to effectively increase the oil yield during the oil extraction process; the third is the crude oil obtained from extraction The oil contains a lot of erucic acid and sediment, which requires effective filtration and refining to ensure the taste quality of the finished oil; only by solving the ...
