The main features and benefits of cold oil press machine

cold oil press machine has a pure natural characteristics, to avoid the traditional high-temperature oil extraction processing adverse effects. Cold pressed oil retains the natural flavor and color of the oil, the complete preservation of the oil in the physiologically active substances (vitamin E has anti-aging function, sterol has a skin effect and enhance the body's metabolic function), cold pressed juice authentic, Is the choice of healthy living.

Main features: Double-screw oil pressing mechanism without sliding bore meshing spiral technology, strong propulsion, press chamber pressure, a crushing clean, the oil rate is high, the residual rate of dry cake low. Special design of the double-screw shaft, the theoretical compression ratio, the oil in the squeeze chamber after 5 times compression and expansion, to achieve thick material layer combined with a thin layer of strong squeeze. Unique cake device, work piece thickness can be stepless adjustment, fragile parts manufactured by carburizing steel and by strict heat treatment, with high strength, toughness, low temperature impact toughness, wear-resistant treatment, long service life. The double-screw oil press low-temperature cold-pressing process cancels the pressing, softening, rolling embryo and steaming frying of the hot pressing process, and has few production equipment, no environmental pollution, low power consumption and low production cost. Vertical cake out of the body to make squeezed screw centering support, work cake thickness can be adjusted; squeeze cage in the vertical plane split, both ends of the hinge support. And thus do not accumulate on the cage residue, oil discharge smooth, easy maintenance;

 But some oil is not suitable for cold oil press machine , cottonseed, peanut, sesame, for example, cottonseed oil in the gossypol toxin and metamorphic oil in aflatoxin, etc., must be refined to remove. And sesame oil and fragrant peanut oil flavor, but also must be hot pressing process can be

Our daily consumption of vegetable oils are mostly hot oil, that is, before the oil in the oil after cleaning, crushing after high-temperature heat treatment, so that a series of internal changes in oil: destruction of oil cells, to promote protein denaturation, reduce fat Viscosity, etc., in order to squeeze oil extraction and improve the oil yield.

But after the high-temperature processing of oil squeezed the color of darker oil, acid prices increased. At the same time, the high-temperature oil extraction makes the bioactive substances (such as vitamin E, sterols, carotenoids, etc.) in the oil loss great loss in the process of squeezing, resulting in waste of resources.

In recent years, with the continuous improvement of people's living standards in the edible oil is becoming increasingly popular cold oil press machine . cold oil press machine  is in the oil before pressing without heating or low temperature of the state, give the oil press squeeze. Compression of the oil temperature is low, acid prices are lower, generally do not need refining, after precipitation and filtration to be refined oil.
