The Egyptian client bought 1 puffed snack food production line in 2019, and bought 1 puffed food production line and 2 fried snacks production lines in 2020. Since the epidemic started last year, we were unable to send engineers to install and debug on site. Therefore, the three newly added production lines were installed and debugged by himself according to our online guidance. The process is really difficult. Due to the time difference, in order to start production as soon as possible, the client is really debugging the equipment regardless of day and night. Of course, our engineers are also very dedicated. Later, the three production lines were finally put into production one after another, but they have not met our client's expectations. He keept trying to adjust the equipment, and finally the products made are getting better and better, even exceeding expectations. Two days ago, the clinet sent our sales manager the snacks pictures he made. The products are really great, and I am happy for the client! With such a good product, it will definitely be welcomed by customers, so sales and profits will be considerable.
