Successful case of nut cracker machine

We have a customer from South African sent us an inquiry at the end of March 2019, and he said that he has a nut processing factory, and wants to buy a black walnut cracker machine. To enable the quality of the machine, he came to China after one month (April 2019), and we picked up him at the airport and then brought him to our factory to test machine. He took some walnuts from South Africa because the walnuts in different countries have different sizes. Our worker adjusted the gap of rollers to fit for the size of raw material before the operation. After testing by himself, he was shocked by the excellent cracking effecting of this walnut cracker, and said that it is the machine that he really wants to buy for his factory.
