Soybean is the most suitable bean. Of course it can also be made of peanuts. The price is concentrated at 4780-4840 yuan/ton, which varies according to regional differences. According to the national acquisition standards, the quality of soybeans is divided into five grades, and the third-class soybeans are standard products, or medium products; The moisture content is 13.0%, and the impurity content is 1.0%. The grade is determined according to the pure grain rate. According to the actual purchase situation and customer demand, Heilongjiang soybeans can be basically divided into four categories. Namely: commodity beans, delivery beans, oil beans and mixed beans. In the usual purchase and sale, people often say that there are mainly two kinds of commercial beans and oil beans. 1, commercial beans: commercial beans are also called clean beans. Mainly sent to the grain wholesale market in the customs, wholesale and retail, the purpose is to germinate and process all kinds of bean products. Commercial beans must be strictly sorted during purchase and before sale, and generally cleaned by grain cleaner or spiral cleaner.

When delivery soybeans are purchased, they are generally cleaned with a standard large-scale flow screen. The quality requirement is Class III of the national standard, especially the moisture requirement is strict, and the soybean for delivery in June 1 1, June 1 and March must be within 15%; The moisture content of soybeans delivered in May, July and September must be within 13%. 3, oil soybean oil beans, usually referred to as oil beans. Mainly sent to various oil processing plants to process soybean oil and soybean meal. Generally, regardless of grade, it mainly detects impurities, moisture and green beans. In the oil factory, the pricing of receiving goods is mostly based on impurity 1.0% and moisture 14.0%. Impurities and moisture exceeding the standard are generally deducted 1: 1. The maximum water content is generally limited to 16%. Exceeding 16% will affect the treatment. The quality standard of oil soybean is not very fixed, and most manufacturers often make appropriate adjustments according to the overall quality of soybean in that year. 4. Miscellaneous beans: Miscellaneous beans are usually called miscellaneous beans, mainly those soybeans that have not been cleaned and screened during threshing. They have large impurities and poor quality, and are mainly sent to oil plants for oil processing. The price or quantity shall be deducted for the part exceeding the receiving pricing standard of the oil plant. There are also some green beans, sticky mud particles (mud surface) and soybeans with excessive red particles. Generally, it is only after consultation with the oil factory that the goods can be purchased and delivered. In recent years, some new soybean varieties have appeared in Heilongjiang, such as large-grain beans, small-grain beans, chickpeas and sprouted beans, which are mainly sold in various wholesale markets of customs. It must be carefully selected and the quantity is limited, so it is not the mainstream variety in soybean purchase and sale. Second, the relationship between soybean quality and price 1. In the actual purchase of soybeans, due to the different qualities of soybeans, the purchase prices of soybeans of various qualities are different. Generally speaking, the better the quality, the greater the cleaning cost and reduction loss, and the higher the price. 2. Soybean daily quotation is generally based on oil beans. The comprehensive comparison in normal years is based on oil beans: commercial beans are generally 40 ~ 60 yuan/ton, delivery beans are generally 20 ~ 40 yuan/ton, and the price of mixed beans is 20 ~ 60 yuan/ton lower than that of oil beans; If there are too many mung beans and red granules, the price difference will be even greater. 3. Due to different purchasing methods and habits, different sources of soybeans, different purchase and sale channels, the price difference of soybeans with different qualities is not the same. There are also differences in quality and price of soybeans sent to oil plants. In some areas, soybeans are purchased through standard large-scale screens, and the quality is very good, which can meet the standard of delivery beans; When purchasing in many areas, poor quality soybeans are cleaned after simple screening, and the quality is good; In some areas, whatever high-quality soybeans are sent, they are purchased directly without finishing, so the purchase price and quotation there are even lower.
