Virgin material in advance of virgin bore within, some virgin materials will have a reverse movement in a small gap pressing screw thread edge and squeeze cages formed on the surface, that material back. Forming material back is caused due to a variety resistance, such as intermittent pressing screw helical teeth; pressing screw thread slit edge and squeeze cages formed on the surface is too large; pressing screw pitch is too large; virgin and virgin material cage surface The friction between the larger; the gap is too small cake mouth caused by the "back pressure" and pressing the theory bore virgin material compression ratio greater than the actual compression ratio and so on. Return is expected to affect the production capacity of oil press and oil yield Luohe press shall be controlled in accordance with the actual requirements. Automatic hydraulic press is mainly used for processing of individual home press. The product is a fully automatic hydraulic screw press, the production of small, but simple and convenient. Now the main products are screw press. There are also cold-pressed spiral screw press Luohe press, relatively inexpensive, but the oil is not high. Rurizhongtian the automatic screw press Luohe hydraulic press plant, it is the country ten years ago in South Korea to introduce technology, by vacuum filtration, automatic temperature control function. Good out of the product oil quality. Fragrant taste Luohe press equipment, the oil rate is still high. Now mainly used in rural areas to do the processing. Or do live in urban areas of processing, so it looks to produce more transparent, give customers more confidence. Conduct of business a great advantage. Many areas now operate according to this model, profits are quite substantial. Luohe Luohe press press manufacturers _ _ Goodwin mechanical press excellent prices offered by Nanyang City, Qi Feng Machinery Co., Ltd. Nanyang City, Qi Feng Machinery Co., Ltd.
