Food oils (liquid fat substitutes, liquid creamers) are mainly divided into two categories: animal fats and plant oils. Their properties and stabilities differ, resulting in different nutritional values. When the rotor pump is in operation, it also considers designing production according to the material characteristics to avoid destroying the nutritional value. These include soybean oil, rapeseed oil, peanut oil, cottonseed oil, sesame oil, sunflower seed oil, flaxseed oil, walnut oil, corn oil, rice bran oil, palm oil, olive oil, camellia oil, and oil from melon seeds, etc. With high viscosity and particulates, the rotor pump addresses issues such as unstable performance, destructive wear, increased maintenance frequency, high repair costs, and low output that traditional pumps encounter during production. Currently, food oil companies using HollySys rotor pumps have achieved favorable applications. Our company continuously innovates and upgrades the pump, reducing the replacement of wear-prone parts, making it more stable, easier to maintain, and capable of conveying alkali-refined oil at low speeds without damaging the oil molecules, thus effectively preserving the quality of food oils.
