Rapeseed oil yield

Oil, salt, sauce and vinegar are indispensable in our diet. These seemingly simple ingredients actually require very complicated processes to make. The edible oils we often eat include soybean oil, peanut oil, corn oil and so on. The prices of these oils vary, and in addition to being related to the cost of the raw materials, they are also related to the oil yield of the rapeseed. If you want to increase the oil yield of rapeseed, you must start with material selection. Understanding the characteristics of different seeds will help to better control some temperature and other adjustments during the production process.

There are many factors that affect the oil yield of rapeseed. From seed selection to equipment and technology, every level must be strictly controlled to maximize the oil yield, reduce costs, and achieve the largest profit share. Below we will introduce in detail the factors that affect the oil yield of rapeseed:

1: Raw materials . The quality of raw materials is the key to determining the oil yield. (Fullness, impurities, variety, dryness and humidity)

2. Equipment . It is very important to choose what equipment for what raw materials. When selecting equipment, you should pay attention to 1: the working pressure of the equipment. (The larger the value, the higher the oil rate) 2: The slag content of the equipment. (The lower the residue content, the higher the oil rate) 3: Residual oil rate of dry cake. (The lower the residual oil rate, the higher the oil yield)

3: Pressing process . There is no fixed rule for what raw materials to use and what pressing process to use.

1: The extraction process varies depending on the origin of the raw materials. (Because the climate in the north and south of my country is quite different)

2: Different raw materials have different properties. (For example: rapeseed and peanuts. Rapeseed is a medium-viscosity, medium-hard shell, medium-oil crop, which produces greater resistance during the pressing process. Peanuts are sticky, soft-shell, medium-oil crops, which produce less resistance during the pressing process. Therefore, the temperature should be lower when pressing rapeseed, and the temperature and moisture content of the raw materials entering the press should also be lower. Generally, the machine temperature should be controlled at around 130 degrees, the raw material temperature at 130 degrees, and the moisture content at around 1.5-2.5%. The peanut machine temperature should be around 140-160 degrees, the raw material temperature between 140-160 degrees, and the moisture content at 2.5-3.5%).

The above introduces the factors affecting rapeseed oil yield from three aspects: raw materials, equipment, and pressing technology. If you want to make the rapeseed oil yield high and produce high-standard edible oil, you must check every level and not miss any details. Because details determine success or failure. Only when the details are taken care of and every good detail is combined, the best result can be achieved.
