In the beginning, I recommend the screw oil press to this customer, while you know single screw oil press does not have the filtering system, he intended to buy an automatic oil press equipped with the filtering device. As the automatic oil press has the advantage of high oil yield, low noise, this machine has been popular with many customers. Then he let me do PI for him and pay for the oil press.
He is very happy when he receives the machine and tell me he may order another 10 sets next year.
