Henan Kingman Mechanical & Electrical Complete Plant Co., Ltd. (KMEC) is founded in the year of 1990, within the import and export of different mechanical products, it deals primarily in the manufacture and foreign trade of complete oil mill plants and correlated equipment, as well as participating in external economic and technical cooperation. Its turnover in 2008 reached US$ 12 million. KMEC has exported complete oil mill projects and common oil mill machinery and oil extraction machinery to over 50 countries and regions by using a highly efficient administrative system and professional experience. Among their product, there is a type called as seed processing plant. For now, seed processing plant is a popular variations of oil mill plant in the market. On the basis of the different physical characteristics of the seeds, seed processing will be done, for instance seed size, length, weight, shape, surface texture, color, affinity to liquid and electrical conductivity.

During the process, the first procedure contains scalping, debearding, hulling and shelling to make the seed flow through the grader and cleaner easily. The removal of impurity, like weed seeds, other crops and broken seeds which are bigger or smaller than the oil seed make up the second procedure. Undesirable materials will be separated from the seed in the last procedure.KMEC supplies cottonseed oil processing, canola oil processing, castor oil processing, corn oil processing, sunflower oil processing, sesame oil processing, soybean oil processing and peanut oil processing. Before extract oil from cottonseed through cottonseed oil plant, cottonseed must be refined to remove gossypol, which is a naturally occurring toxin that protects the cotton plant from insect damage. During the canola oil processing, graded canola seed will be cleaned by some different methods air aspiration, indent cylinder cleaning, sieve screening, or a combination of these then it will be preconditioned and extracted. Castor seed is the source of castor oil, there are two main procedures in castor oil plant to process quality castor oil from castor seeds, one is oil extraction and the other is oil purification. Corn oil is widely used throughout the world, qualified corn oil is available by these equipments, generally, corn oil processing need to break the corn grain and extract corn oil from the broken corn grain. Sunflower oil plant is getting more and more popular for economic reasons, sunflower oil processing contains seed preparation and cleaning, seed grading, bagging and storing. Sesame oil processing is difficult unless do with the right oil processing method and quality oil processing machinery, correct sesame oil processing must take the characteristic of sesame oil into account. The soybean oil plant is one kind of seed processing plant, several machinery will be taken into use in order to process soybean oil. KMEC peanut oil processing plant can produce qualified peanut oil with professional peanut oil processing technology.
