Embodiment Construction

[0019] The raw rapeseed kernels are passed through vibrating sieves, stone removers, magnetic separators, etc. to remove dust, side stones, iron and other impurities in the raw materials, and then the rapeseed kernels are sent to the flat dryer, and the rapeseed kernels are The moisture content is reduced to 3-6%, and 70-80% of the rapeseed skin is removed with a peeling machine; the peeled rapeseed kernels enter the frying machine to fry the seeds, add water while frying, and control the temperature of the rapeseed kernels at 130- 160°C, when the moisture content of the rapeseed kernels reaches 2-4%, stop frying seeds, and the smoke generated during the frying process is removed by the suction system; the fried rapeseed kernels directly enter the 110-type oil press for pressing , to obtain fragrant crude oil and press cake; after the fragrant crude oil is precipitated, it is cooled to 20-30°C by heat exchange, and then filtered through a plate and frame filter for a second tim...

Abstract

The invention discloses a production method of strong and fragrant rapeseed oil. The production method comprises steps as follows: cleaning, drying, coat removing, seed frying, smoke removing, pressing and low-temperature fine filtration. The production method has the advantages as follows: (1) pressing after coat removal is adopted in the production method, impurities such as a large quantity of pigments, erucic acid and the like in coats are prevented from entering oil, the refining difficulty is reduced, and the oil quality is improved; (2) crude rapeseed oil is refined through normal-temperature filtration, hydration degumming, vacuum drying and the like are omitted, energy consumption is reduced, the yield is increased, and damage to fragrant substances in the rapeseed oil is reduced; (3) compared with the prior art, the method is simple in process and easy to operate.

Description

technical field [0001] The invention relates to a method for producing fragrant rapeseed oil, which belongs to the technical field of edible oil processing. Background technique [0002] At present, most of the processing methods of Luzhou-flavored rapeseed oil are to directly fry the seeds after cleaning the rapeseed kernels, and then squeeze and refine the finished oil. The content of erucic acid is high, which can only reach the standard of four-grade rapeseed oil. Therefore, be badly in need of a kind of new method to solve the deficiency of prior art. Contents of the invention [0003] The purpose of this invention is to provide a new method for producing strong-flavored rapeseed oil. The rapeseed oil produced by this method not only has strong fragrance, but also has light color and low erucic acid content, reaching the national first-class oil standard. [0004] The technical solution adopted in the present invention is: a method for producing strong-flavored rape...
