Large-scale avocado oil extraction

Large-scale avocado oil extraction typically employs a "cold pressing + centrifugation + light refining" process to meet the requirements of large-scale production and high quality. Specifically:
Raw Material Pretreatment
Continuous Washing and Destoning: A combination of rollers, brushes, and air classifiers is used to continuously wash the avocados, removing surface mud, impurities, and foreign matter such as metal and gravel, ensuring the purity of the raw material.
Oil Extraction
Low-Temperature Twin-Screw Pressing:** The washed and destoned avocados are fed into a low-temperature twin-screw press and pressed at 30-40℃, resulting in a residual oil content of ≤10%, yielding crude oil and pressed cake. Low-temperature pressing effectively preserves the nutrients in avocado oil and avoids the damage to oil quality caused by high temperatures.

Centrifugal Clarification
Three-Phase Centrifugal Clarification: A horizontal screw centrifuge is used for initial centrifugation to separate water, solid particles, and other impurities from the crude oil, resulting in a relatively clear oil phase. A secondary centrifugation process using a disc centrifuge further removes minute impurities and moisture, resulting in even higher oil purity.

Oil Extraction Refining
Wintering Dewaxing: The clarified oil is placed in a wintering tank and crystallized at 5°C for 8 hours, causing the wax in the oil to crystallize and precipitate. The wax is then removed by filtration, improving the oil's transparency and stability.
Micro-vacuum Deodorization: The winterized and dewaxed oil is sent to a micro-vacuum deodorization device and treated at 120°C for 30 minutes to remove any potential off-odors while maintaining the oil's high smoke point and nutritional content.
Large-scale avocado oil pressing equipment has a high budget, generally around 1.5-2.5 million RMB, including cold presses, centrifuges, wintering tanks, etc. This process route has a high yield, with a crude oil yield of approximately 85% and refining losses of 5%-7%.
