Step 6/2: Neem seed oil extraction using Neem oil machine: Enclose the hot material (dough) in a fine cloth. You can also use empty muslin or cotton bag capable of allowing liquid passage and further placed in the barrel of the Neem oil extraction machine. Inside the barrel, press the metallic lid which is on the dough. Turn the metallic wrench bar clockwise direction to press the neem dough. Put sufficient pressure on the dough. This will start the flow of neem oil from the mouth side of the barrel which you have to collect.
