Description
Technical field
The method for preparing high-quality rapeseed oil is integrated the present invention relates to cryogenic technique, belongs to Oil processing technical field.
Background technology
China is not only oil seed production big country and grease consumption big country, while is also oil plant fats and oils processing big country.With regard to grease
For processing, the fats and oils processing ability in China is big, as many as number of the enterprise belongs to the first in the world.According to statistics, 2008 are ended, entirely
100,000,000 tons of state's Oil processing ability, 30,000,000 tons of affinability, edible vegetable oil total output are 24,000,000 tons, and refining oil yield is
18000000 tons, 236,200,000,000 yuan of scale more than Oils and fats enterprise sales volume, oil and fat product total value is up to 14,000,000,000 yuan/year.Oil prodution industry has become
To be only second to butcher and the second largest agricultural and sideline food processing industry of meat industry, its 20% share is accounted for, in Chinese national economy
In have highly important status and effect.Edible oil industry is the mainstay industry concerning national economy and the people's livelihood, is food industry
Important component, the gross output value accounts for the 1/10 of the food industry output value up to more than 4,400 hundred million, while is also to be related to state food safety
With the important industry of national health.However, China's edible vegetable oil industry problem encountered should not be underestimated, the production of China's edible oil
Industry dependence on external supply is serious, and edible oil safety is classified as one of national strategy safety by China.
In traditional refining pattern of China's rapeseed oil, nutrition destruction, high energy consumption, contaminant capacity existing for chemical refining are big etc. asks
Topic；Only in refining procedure, more than crude oil power consumption 20kwh, more than coal consumption 30kg per ton generate more than 210L oil-containings and give up containing alkali
Water, also there are soap stock, waste oil, spent bleaching clay, hazardous solvent gas, dead catalyst discharge, enterprise is that discharge waste material is made to meet environmental protection
It is required that, it has to oil and fat product cost is significantly increased in flower substantial contribution input waste disposal.Therefore, exploitation has traditional dish
The nutrient retention rates such as the cold press rapeseed oil and vitamin E, sterol of seed oil peculiar flavour have up to 90% appropriate refined rapeseed oil
Help improve China's edible oil degree of self-sufficiency, ensure resident's edible oil safety.
It is a very important ring in food service industry to toast flavouring, has and extends effective period of food quality, sterilization, improves flavor etc.
Effect.The method for being usually used in food heating at present has convective drying --- including heated-air drying, heat pump drying and superheated steam
Dry, radiant drying --- including microwave drying and infra-red drying, a good roasting mode should have at low cost, baking
The characteristics of speed is fast, baking quality is high and bactericidal effect is good.Convection current heated-air drying is using more in current industrial production
A kind of baking mode, it is low for equipment requirements, have the characteristics that easy to operate, rate of drying is relatively fast, sterilization effect is preferable, but
It is its high energy consumption, energy utilization rate is low, and due to needing high temperature in the drying process, it can be to the mouthfeel, appearance and battalion of product
It forms to grade and can cause a degree of destruction, be not a kind of efficiently effective drying mode；Microwave drying has many advantages, such as,
Penetrating medium using electromagnetic wave makes its interior molecules vibrate heat production, and heat is generated inside material so that each position of material
The rate of heat addition is identical, and rate of drying is fast, low energy consumption, dry from spatio-temporal influence, can carry out large-scale industry
A kind of more drying modes is applied in dry production and at present research, but microwave drying influences ratio to the quality of material
It is larger, fragrance and texture of the bad drying parameter often to material is controlled to cause big damage, and due to microwave radiation pair
Human body is harmful to, and the spilling of microwave is avoided in microwave drying process, and higher requirement is proposed to drying equipment, is caused high
Initial cost.
