Walnut oil press machine

Walnut oil is an edible vegetable oil that uses walnut kernels as raw materials and is physically pressed. It is considered to be a high-level health care edible oil. The oil content of walnut is as high as 65% to 70%, ranking first among all woody oils. Select high-quality walnuts as raw materials, and use the world’s leading pressing technology to produce natural walnut oil. The walnut oil press machine belongs to the hydraulic oil press, which adopts the cold pressing method. With the walnut oil cold press machine, the final walnut oil can well preserve the nutrients and natural fragrance and has good color and flavor. The walnut oil making machine has multiple uses, also suitable for sesame, olive, coconut, almond, etc. The walnut oil extraction machine has been widely used in oil mills, nut processing workshops, oil processing plants, etc.

Nutritional value and efficacy of walnut oil

The nutritional value of walnut oil is extremely high, and it has always been comparable to olive oil. The fat contained in every 100 grams of walnut kernels is about 63 grams to 76 grams, and the main components of its fat are glycerol linoleate, linolenic acid, and glycerol oleate, which are essential fatty acids for our body, and Easily digested and absorbed by the human body. So eating walnut oil is very beneficial to human health.

Walnut oil has the effects of laxative, bright hair, brain, kidney, and intestines. After the walnut kernels are pressed for oil, they are fresh and pure, rich in nutrition, light in taste, and easy to digest and absorbed by the human body.

The oil extracted from walnuts is divided into two types, one is the method of hydraulic low-temperature pressing, and the other is pressed by the method of screw-type hot pressing The oil yield of the two pressing methods is also different. Nowadays, more and more people prefer cold-pressed walnut oil.

The cold pressing method of the walnut oil press machine is processed under the production environment of 60-70 degrees. In terms of technological process, after the high-quality walnuts are shelled, the walnut kernels are obtained, and the walnut kernels are pressed by the oil press. The hydraulic oil press uses hydraulic oil as the medium for pressure transmission to generate working pressure, and the pressure can reach 55MPa so that the walnuts are squeezed into the feeding chamber to squeeze out the oil. Walnut oil making machine is composed of two parts: hydraulic system and oil press body. The pressure of the liquid is created by a plunger pump. The general output is 30-400kg/h. The pressing time of each batch is about 7-10 minutes.

Cold-pressed oil does not need to be heated or fried, which can well preserve the nutrients of walnut oil. The quality of the oil is very good. The extracted oil has pure natural characteristics, the taste and color are very good, and the impurities are relatively high. less, so that the physiologically active substances in walnut oil can be well preserved.

Hot pressing is usually carried out using screw presses. The raw materials are subjected to rotating and propelling crushing friction and then subjected to high-temperature heating treatment so that oil is more likely to be released. The internal changes of the oil will reduce the viscosity of the oil to a certain extent, and some active substances will be lost, such as vitamins and carotenoids, so the nutritional value of such oil is lower than that of cold-pressed oil.

The pressure point of the hydraulic oil press is larger than that of the screw oil press, and the pressing of the walnut oil press machine is relatively complete. The walnut kernel has a high oil content, and if it is equipped with a hydraulic oil press, the oil yield will be higher. If the daily output is small, it is very suitable to use a hydraulic oil press. If the daily output is large, it is best to use a screw oil press. Now oil press machines are more automatic and intelligent, easy to operate, and have good effects in all aspects.

What factors affect the oil yield of walnuts?

The fat content of every 100 grams of walnut kernels is 63 to 76 grams. The main components of its fat are glycerol linoleate, linolenic acid, and glycerol oleate, which are essential fatty acids for the human body. Walnut oil is a high-grade edible oil. The oil content of walnut kernels is as high as 65 to 70%, and 25 to 30 kg of oil can be extracted per 100 kg of shelled walnut kernels. In addition, the oil yield of walnuts has a lot to do with the pressing methods of a walnut oil press machine, walnut varieties, and maturity. The better the walnut variety, the higher the oil yield. Different walnuts have different oil yields. Generally, the oil yield of walnuts is about 50%. The oil yield of some walnuts can reach up to about 70%, while the oil yield of some poor-quality walnuts is only about 20%.
