NOT FOR OLIVE OIL- please do not use it to press olive oil because of the lengthy pressing process! For other unconventional materials, you can contact servicestaff to confirm before purchase! PREHEATING IS A MUST! - For both methods, the machine must be preheated for 8-10 minutes, absolute cold pressing at 30°C is not possible! COLD PRESSING & HOT PRESSING - The cold pressing method can preserve richer natural nutrients and is suitable for dry materials. The hot pressing method presses high moisture materials that need to be heated in a pot/microwave beforehand and provides a more intense flavour and high oil yield. EASY OPERATIONS&CLEANING - Preheat the machine for 8-10 minutes, then pour the raw materials into the hopper and start pressing. When cleaning the machine, put on the insulated to remove the screws, hopper, pressing chamber and rod, and use the brush to clean the parts with water and dry. CORE PRESS TECHNOLOGIES - With the "Secondary Oil Return" technology of the superior pressing chamber and 1200W industrial motor, the oil press will maximise its oil yield. The high-hardness bearing ensures continuous operations of the machine around the clock, and the service life of the motor is up to 5 years.
