Press press refers to the aid of a basic introduction to the role of mechanical force, by raising the temperature, activate the oil molecules, the oil from the oil squeezed out of the machine. Can be divided into domestic press, oil hydraulic mechanism, screw-oil machine, the new hydraulic press, efficient fine filter press, automatic oil press. Press materials, that is, oil-bearing crops in accordance with the type of plant material and animal feed into press manufacturers, in general, the production process, we mainly plant-based raw materials. When the screw press oil extraction troubleshooting of the excessive residue: (1) oil is too dry screw press Nanyang new offer, very fine cracks discharged from the juice increased, this time to re-adjust the fuel moisture. (2) The fuel is too wet, do not form pressure press, diesel automatic oil prices can not be separated, if this time is too large drain joints, cracks slag it out from the oil, water and oil should be adjusted juice bar assembly tightness. Automatic oil prices, Goodwin machinery (certified), press provided by Nanyang City, Qi Feng Machinery Co., Ltd. Nanyang City, Qi Feng Machinery Co., Ltd.
