Therefore, the hydraulic oil press still occupies a certain proportion in the oil pressing industry, and the hydraulic fully automatic oil press has gradually replaced the old mechanical oil press in the past decade.

[0003] At present, the automatic pressing can only be selected in a certain pressing period. After the oil press is started, a staff member must observe the pressing status, and only when the oil starts to flow out can it enter the automatic pressing. After entering the program, it will cycle according to the set interval time until the upper limit, and then start with high and low levels, then reach the upper limit, and then start again, and continue to work in a cycle.
