Selecting high - quality peanuts and sesame seeds is the first and crucial step in home oil extraction. You should look for peanuts and sesame seeds that are plump, free from mold, and have a natural, fresh smell. For peanuts, choose those with intact skins and no signs of insect damage. Sesame seeds should be clean, shiny, and uniform in size. High - quality raw materials can significantly increase the oil yield. For example, using high - grade peanuts can potentially increase the oil yield by about 10% compared to lower - quality ones.
Pre - treatment of peanuts and sesame seeds plays a vital role in the oil extraction process. The roasting temperature control and the peeling and impurity removal processes have a significant impact on the oil yield. When roasting peanuts and sesame seeds, the temperature should be carefully controlled. For peanuts, the optimal roasting temperature is around 150 - 160°C, while for sesame seeds, it is about 160 - 170°C. Roasting at the right temperature can break down the cell walls of the oilseeds, making it easier for the oil to be released. Additionally, removing the skins and impurities from the oilseeds can improve the quality of the extracted oil. For instance, after removing the peanut skins, the oil extracted is clearer and has a better taste.

Different oilseeds have different optimal oil extraction temperature ranges. For peanut oil extraction, the best temperature is between 120°C - 160°C. The Penguin Group's intelligent temperature - controlled oil press can accurately control the temperature within this range, ensuring that each batch of oil products is pure and up to standard. For sesame oil, the optimal temperature range is 130°C - 170°C. You should set the temperature according to the type of oilseeds and the instructions of the oil press. Incorrect temperature settings can lead to low oil yield or poor - quality oil.
The automatic cleaning system of the oil press is essential for ensuring the hygiene of the equipment and its long - term stable operation. After each use, you should run the automatic cleaning system immediately. Use appropriate cleaning agents and follow the correct cleaning procedures. Regular cleaning can prevent the accumulation of oil residues and impurities, which can affect the performance of the oil press. For example, if the oil press is not cleaned regularly, the oil yield may decrease by about 5% over time.
During the oil extraction process, you may encounter some common problems such as low oil yield, cloudy oil, and unpleasant odors. If the oil yield is low, you need to check the quality of the oilseeds, the roasting process, and the temperature settings. For cloudy oil, it may be due to insufficient impurity removal or improper temperature control. To solve the problem of unpleasant odors, you should check the freshness of the oilseeds and the cleaning status of the equipment. Here are some tips from industry experts:
"Regularly check the performance of your oil press and follow the correct operating procedures. This can significantly reduce the occurrence of common problems." - An industry expert
Let's take a look at some real - user cases. Mr. Smith, a user from the United States, used to have problems with low oil yield and cloudy oil when using a traditional oil press. After switching to a modern oil press with intelligent temperature control and an automatic cleaning system and following the correct oil extraction process, his oil yield increased by 15%, and the oil quality improved significantly. Some practical tips from users include storing the oilseeds in a dry and cool place to maintain their quality and using a small amount of oil for initial testing when using a new oil press.
