Our peanut oil press machine adopt the latest pre-press – oil extraction process technology, at present, this technology is the most advanced in the world, and it makes up for lack of traditional oil press and improve the oil yield, ensure the quality of peanut oil ,improve the quality of peanut meal, to provide a guarantee as high protein forage material.
Zhengzhou QIE Peanut oil press machine features:
1, the world’s most advanced oil extraction technologies. The traditional oil extraction are one-time pressing, leading to the oil yield is not high, waste oilseeds, zhengzhou QIE use pre-press – oil extraction technology to reduce the residual oil rate of oil cake and improve the quality of peanut meals.
2, the unique environmental initiatives. Oil extraction systems, henan huatai unique exhaust absorption system, absorbing good effect, in line with environmental standards required in many countries, to solve customer worries.
3, reasonable advanced energy-saving design. solvent recovery system in oil extractor are provided, the solvent can be repeatedly used, heat energy also can be repeatedly used, saving the amount of solvent and steam, for customers to save costs.
In order to improve oil yield rate and get high quality peanut oil, the peanut oil extraction plant should consist following processes: peanut kernel pretreatment, peanut oil prepressing, peanut oil solvent extraction and crude peanut oil refining.
Intermittent process preheats peanut crude oil to 80 ~ 85 ℃. The amount of water in crude oil bases on colloid content, and generally 3-5 times of the gum content, water temperature at 85 ~ 90 ℃ (5 ℃ higher than oil temperature). Finish water adding in 40-60min, along with 60-70r/min stirring, continue stirring 3-5min after adding water, and stand for precipitation 2-4h.
Heat degummed vegetable peanut oil to 25 ~ 135 ℃, dehydrated into a vacuum dryer 20 ~ 30 min. Moisture of dehydrated oil is less than 0.1% (after degumming of crude oil via the oil contained in the 0.3% to 0.5 % of the water will affect the adsorption capacity of bleaching clay section).
Degumming of peanut oil can remove grease in oil pigment to improve oil color, adsorption of aflatoxin and trace metals, phospholipids, other gum and other impurities. It ensures high quality of peanut oil and improves oil stability.
Control oil temperature to 250 ~ 270 ℃ when decolorized peanut oil enters into deodorizer, in direct steam injection, the free fatty acids, ketones, aldehydes and other impurities are removed from the oil, the thermal decolorized action also occurs, and the pigment composition is cleaved distilled from the oil. Deodorized vacuum (absolute pressure) controlled at 266 Pa, the deodorization time is about 2h.
