Oil mills either process externally or squeeze oil to sell oil. It must be fuel. Lai seed is one of the common oils. The use of rapeseed oil press is mainly to squeeze rapeseed, whether it is fresh rapeseed or stale rapeseed, there will be some difference in the pressing process. Therefore, it is necessary to distinguish between new rapeseed and old rapeseed during operation, so that the machine can achieve a good oil yield.
The main difference between fresh rapeseed and aged rapeseed is that fresh rapeseed is just harvested, and after simple drying, it contains a little more water, while aged rapeseed is stored for a long time and contains relatively less water. There will also be some differences in the taste of the pressed oil. Fresh rapeseed tastes more fragrant.
Regardless of whether it is fresh rapeseed or stale rapeseed, the oil extraction process is the same, all of which need to go through the three steps of frying seeds, squeezing oil, and filtering oil. The difference is that rapeseed needs a good dry humidity before pressing the oil. Therefore, in the process of frying seeds, it is necessary to determine the time and temperature of frying seeds according to the freshness of rapeseeds. The oil yield of new rapeseed does not have much influence. Mainly depends on the quality of rapeseed (fullness, impurities).
