Problems solved by technology

[0003] At present, the Luzhou-flavor rapeseed oil market is relatively chaotic. The processing conditions and processing equipment of each enterprise are different, and the product quality is different. Adding chemical reagents to refine rapeseed oil caused the rapeseed oil to lose its strong aroma. At the same time, common refining technologies on the market include nano degumming, fine filtration degumming, dephosphorization with dephosphorization agents and membrane ultrafiltration, but These technologies have high investment and high production costs, and are not suitable for the market

Embodiment 1

[0027] A processing technology for Luzhou-flavor rapeseed oil, comprising the following steps:

[0028] S1. Raw material selection: select fresh rapeseed with plump grain and water content less than or equal to 8%;

[0029] S2. Raw material cleaning, stone removal, magnetic separation, and color separation: Vibrating screens, specific gravity stone removal machines, magnetic separators, and color sorters are used to remove side-by-side mud or side-by-side stones and other vegetable impurities, and sort immature grains , Damaged kernels, mildewed kernels, and aged kernels, after cleaning, the rapeseed content is less than or equal to 0.5%, and the leftovers contain rapeseed less than or equal to 1.5%;

[0030] S3. Seed frying: Use a drum seed frying machine, the temperature of the frying seeds is 150-180°C, and the exhaust gas temperature is less than or equal to 240°C. According to the different moisture content of the raw materials, the time for frying seeds is extended or re...

Abstract

The invention discloses a fragrant rapeseed oil processing technology and belongs to the field of cooling oil processing. The technology of the invention comprises the following steps: selecting freshrapeseeds with full seeds and with water content being less than or equal to 8%; raw material cleaning, stoning, magnetic separation and color sorting; seed frying: a roller seed frying machine is selected, the seed frying temperature is 150-180 DEG C, and smoke exhaust temperature is less than or equal to 240 DEG C; pressing: a No. 10 oil press is adopted, the pressing temperature is 150 DEG C,and the pressing moisture is 1.5%; S5, clarification: preliminary impurity removal is carried out by a clarification tank, the solid impurity content is 3-5 times greater than the colloid content andis 3-5% of the grease content; cooling: water of 9 DEG C is used for circulation in a cooling tank, and the stirring speed is 15-10 r / min; filtering: a plate-and-frame filter is used, oil inlet amountis small at the beginning, and the oil inlet amount is increased after filtered oil is qualified through sampling inspection, and constant-temperature filtration is maintained. The manufacturing process is scientific and reasonable, no chemical reagent will be contacted in the refining process, and the rapeseed oil is fragrant and pure and has high nutritive value.

Description

technical field [0001] The invention relates to the field of grain and oil processing, and more specifically relates to a processing technology of strong-flavor rapeseed oil. Background technique [0002] Due to the upside-down purchase price and product selling price of domestic rapeseed, the rapeseed processing loss in 2015 was 200-300 yuan / t. In order to survive, large-scale rapeseed oil factories turned to the production of soybeans and strong-flavored rapeseed oil. Now the strong-flavored rapeseed The output of seed oil exceeds 30% of the total amount of domestic rapeseed oil, and the total consumption of Luzhou-flavor rapeseed oil exceeds 1.5 million tons, and it shows an increasing trend. [0003] At present, the Luzhou-flavor rapeseed oil market is relatively chaotic. The processing conditions and processing equipment of each enterprise are different, and the product quality is different. Adding chemical reagents to refine rapeseed oil caused the rapeseed oil to los...
