What is the difference between cold pressing and hot pressing?

Detailed Engineering Analysis

Hot pressing may recover more oil from some materials, but its performance should not be used to promise the same yield in cold mode. Compare both methods using the same seed batch and record preparation, oil temperature, saleable oil and remaining cake. If you plan to market a cold-pressed product, establish the applicable production and labeling requirements before selecting the process. A machine with a heater can support different operating modes; its name alone does not verify the oil's production method.
