Meanwhile Chewing Jam center dog food processing line particles adjacent the screw will rotate along with screw's rotating, causing every particle adjacent the screw will rotate along with screw's rotating, causing every particles insides the chamber to posses different speed. Therefore, relative movement among particles creates heat which is necessary during manufacturing because of helping protein change properly, damage cold oil ,decrease plasticity, decrease oil, elasticity, resulting in high oil productivity.

The all-wet process uses raw coconut rather than dried copra, and the protein in the coconut creates an emulsion of oil and water.The more problematic step is breaking up the emulsion to recover the oil. This used to be done by prolonged boiling, but this produces a discolored oil and is not economical. Modern techniques use centrifuges and pre-treatments including cold, heat, acids, salts, enzymes, electrolysis, shock waves, steam distillation, or some combination. Despite numerous variations and technologies, wet processing is less viable than dry processing due to a 10-15% lower yield.
Proper harvesting of the coconut makes a significant difference in the efficacy of the oil-making process. Copra made from immature nuts is more difficult to work with and produces an inferior product with lower yields.
Chewing Jam center dog food processing line Conventional coconut oil processors use hexane as a solvent to extract up to 10% more oil than produced with just rotary mills and expellers. They then refine the oil to remove certain free fatty acids to reduce susceptibility to rancidification. Other processes to increase shelf life include using copra with a moisture content below 6%, keeping the moisture content of the oil below 0.2%, heating the oil to 130-150 °C (266-302 °F) and adding salt or citric acid.
