Oxidating a plant
That shows the temperature changed a total of 9 degrees.
The drop was not as significant on the other juicers since the augers are primarily made of plastic, which does not transfer cold as well.
Third, you see the temperature of the carrot pulp, which is fairly consistent with the temperature of the blade. This can possibly be explained by the healthy juicer electric having a plastic auger with metal insert.
The temperature of the blade was roughly somewhere in the middle.
Some juicers were more effective at lowering the blade temperature, such as the Lequip mini with its stainless steel blade, it really seemed to cause the temperature to drop on the blade.
Oxidation created during the juicing process is just one factor that should be considered if you own, or are looking to purchase a juicer.
