Embodiment 1

[0039] Use rapeseed (tocopherol content 24.254mg / 100g) as raw material to wash and drain, pour the drained rapeseed into a flat-bottomed open frying pan for frying, the temperature of frying seeds is 190°C, and the time of frying seeds is controlled For 50 minutes, a ventilation device is installed above the frying pan to remove the smoke. The fried seeds are quickly passed through a windmill to remove the burnt skin, and quickly spread out and cool down to 100°C. The cooled rapeseed is ground by a double-roll mill, the bearing of the mill is lubricated with rapeseed oil or food-grade lubricating oil, and the ground powder is passed through a 40-mesh sieve. The ground powder is sent to the steamer and steamed with high-temperature water steam. The moisture content of the steamed powder is 9%, and the cake is immediately wrapped with edible grade cotton cloth to ensure that the temperature of the cake before pressing is 70°C. Then put the rapeseed cake wrapped in steamed flour...

Embodiment 2

[0044]Rapeseed (with a tocopherol content of 23.881mg / 100g) was used as a raw material to wash and drain. Pour the drained rapeseed into a flat-bottomed open frying pan for frying. The temperature of the frying seeds is 200°C, and the frying time is controlled to be 60 minutes. A ventilation device is installed above the frying pan to remove the smoke. The fried seeds are quickly passed through 2 windmills to remove the burnt skin, and spread out quickly to cool down to 110°C. The cooled rapeseed is ground by a double roller mill, the bearing of the mill is lubricated with rapeseed oil or food-grade lubricating oil, and the ground powder is passed through a 50-mesh sieve. The ground powder is sent to the steamer and steamed with high-temperature steam. The moisture content of the steamed powder is 12%, and the cake is immediately wrapped with edible grade cotton cloth to ensure that the temperature of the cake before pressing is 80°C. Then put the rapeseed cake wrapped in ste...

Embodiment 3

[0049] Rapeseed (with a tocopherol content of 17.845mg / 100g) was used as a raw material to wash and drain. Pour the drained rapeseed into a flat-bottomed open frying pan to fry the seeds. The temperature of the frying seeds is 220°C, and the frying time is controlled to be 70 minutes. A ventilation device is installed above the frying pan to remove the smoke. The fried seeds are quickly passed through 3 windmills to remove the burnt skin, and quickly spread out and cool down to 120°C. The cooled rapeseed is ground by a counter-roll mill, the bearing of the mill is lubricated with rapeseed oil or food-grade lubricating oil, and the ground powder is passed through a 60-mesh sieve. The ground powder is sent to the steamer and steamed with high-temperature steam. The moisture content of the steamed powder is 15%, and the cake is immediately wrapped with edible grade cotton cloth to ensure that the temperature of the cake before pressing is 90°C. Then put the rapeseed cake wrapped...

Abstract

The invention discloses a method for wood squeezing of rapeseed oil. The method comprises the following steps of: after washing raw material rapeseeds with water and draining the water, frying the rapeseeds at 190-220 DEG C for 50-70min, removing burnt parts, and spreading the fried rapeseeds to obtain rapeseeds to be ground; grinding the rapeseeds to be ground into powder, steaming the powder by using water vapor, then wrapping the steamed powder into cakes; and putting the cakes on a wood squeezer, and precipitating squeezed oil to obtain finished product oil. The oil yield of the method is high (35% or higher), and the prepared rapeseed oil is sable in quality, rich in flavor, pure in taste, rich in nutrition, and low in content of polycyclic aromatic hydrocarbons, wherein the content of benzo[a]pyrene is less than 5[mu]g / kg, the total amount of four polycyclic aromatic hydrocarbons (benzo[a]pyrene, benzo[a]fluoranthene, benzo[b]fluoranthene and chrysene) is less than 20[mu]g / kg, and the content of tocopherol may reach 752.89mg / kg.

Description

technical field [0001] The invention belongs to the technical field of edible oil processing, and in particular relates to a method for pressing rapeseed oil. Background technique [0002] Rapeseed oil is rapeseed oil, also known as coriander oil, which is one of the main edible oils in my country. Wood pressing is a traditional pressing oil production process in my country. Its principle is wedge-type physical pressing. Wood pressing oil uses rapeseed as the main raw material. Wood mustard rapeseed oil is loved by consumers because of its strong flavor and pure taste. The traditional wood-pressed rapeseed oil process has low requirements on raw materials and processing environment. Without a perfect production standard, it is easy to cause the pressed wood-pressed rapeseed oil to contain a large amount of carcinogen benzo[a]pyrene and other polycyclic Aromatic hydrocarbons are harmful to the health of consumers. [0003] Benzo[a]pyrene is a strong carcinogen, the most to...
