Our diet is inseparable from oil, salt, sauce and vinegar. These seemingly simple ingredients have very complex processes when making them. The cooking oils we often eat include soybean oil, peanut oil, corn oil, etc. The prices of these oils are different, which is not only related to the cost of raw materials, but also to the oil yield rate of rapeseed. To make rapeseed oil yield high, you must start by selecting materials. Understanding the characteristics of different seeds will help better control some temperature adjustments during the production process.
There are many factors that affect the oil yield of rapeseed. From seed selection to equipment and technology, it is necessary to check it layer by layer in order to achieve the highest oil yield, reduce costs, and achieve the maximum profit share. Let me introduce in detail what factors affecting rapeseed oil yield:
1: Raw materials
. The quality of raw materials is the key to determining the oil yield rate. (Plumpness degree, impurity, variety, dry and humidity)2: Equipment
. What raw materials are used for which equipment is very important. When selecting a device, you should pay attention to 1: The working pressure of the device. (The higher the oil rate) 2: The slag content of the equipment. (The lower the residue content, the higher the oil rate) 3: Dry cake residual oil rate. (The lower the residual oil rate, the higher the oil rate)III: Pressing process
. What raw materials are used for and which pressing process is not fixed.1: The raw materials are produced in different places and the pressing process is also different. (Because the climate difference between 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, and medium-oil ratio crop, which produces greater resistance during the pressing process. Peanuts are a viscosity, soft shell, and medium-oil ratio crop, which produces less resistance during the pressing process. Therefore, the temperature of the rapeseed should be lower, and the feeding temperature and moisture content of the raw materials should also be lower. Generally, the machine temperature should be controlled at about 130 degrees, the raw material temperature should be 130 degrees, and the moisture content is about 1.5-2.5%. The peanut temperature should be around 140-160 degrees, the raw material temperature should be between 140-160 degrees, and the moisture content is between 2.5-3.5%).
The above introduces the influencing factors of rapeseed oil yield from three aspects: raw materials, equipment, and pressing process. If you want to make rapeseed oil yield high and produce high standard cooking oil, you must check it layer by layer and not miss every detail. Because details determine success or failure. Only by doing the details well and composing every good detail is the best result.
