Press pressing method to distinguish between raw material pretreatment of raw materials from the pre-pressed to distinguish between cold-pressed and hot pressing method, also known as cooked pressing method. Is the raw cold pressed without roasting or steaming raw materials directly into press squeezed out of oil, this method is relatively shallow oil colors, brighter colors, but the oil is low, and the oil does not taste strong, mellow . And cooked in front of virgin oil crops should press after drying, it aims to reduce raw water, increasing fat molecule activity and mobility greaves separator to improve the oil yield, oil quality assurance fragrant taste. But also undermines the chemical composition of the oil organization, resulting in color of the oil deeper, darker. Screw press is mainly used for individual home working with a hydraulic press that the product is of automatic oil production is not, but easy. Now the main products are screw press. There are also cold-pressed screw press, less expensive than automatic screw press, but the oil is not high. Rurizhongtian the automatic screw press, it is ten years ago in South Korea to introduce domestic technology, by vacuum filtration, automatic temperature control function. Good out of the product oil quality. Fragrant taste, 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 regions are now run a small diesel according to this pattern separator Goodwin best profits are quite substantial. Multifunction screw press screw press manufacturers offer versatile screw press quoted the oil is high - compared to the old equipment, the normal oil rate 2-3 percentage points higher than the latest diesel horizontal separation machines, each working an average of more pounds of peanuts 2-6 pounds, annual economic benefits are substantial. Energy saving - equivalent to 40% lower production of electric power, with an average savings of 6 kWh per hour, the production can save 30 yuan electricity. Multifunction screw press Shandong manufacturers offer the lowest labor - labor savings equivalent to 60% yield, 1-2 people can organize production, the labor savings effect of about 40 yuan. Wide use - a machine can be pressed peanut, flax, sesame, rapeseed, sunflower, cottonseed, soybean and other 30 kinds of oil crops. Greaves multistage centrifugal separator press preferred Goodwin, a virgin net. Screw press photograph pure oil - vacuum filtration residue to protect the oil clean, hygienic and quarantine standards. Small footprint - oil mill will be able to meet the needs 10-20 square meters. Decanter centrifugal separator diesel, Goodwin machinery (certified), diesel oil separator is provided by Nanyang City, Qi Feng Machinery Co., Ltd. Nanyang City, Qi Feng Machinery Co., Ltd. (www.qifengjixie.com) is Nanyang, Henan, edible oil processing machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
