Walnut oil is oil extracted from walnuts Juglans regia (Persian walnuts). Each 100 g of oil provides about 63.3 g polyunsaturated fatty acids, 22.8 g monounsaturated fats, and 9.1 g saturated fats. It contains no cholesterol. 

Unlike most nuts that are high in monounsaturated fatty acids, walnut oil is composed largely of polyunsaturated fatty acids (72% of total fats), particularly alpha-linolenic acid (14%) and linoleic acid(58%), although it does contain oleic acid as 13% of total fats

Walnut oil is edible and is generally used less than other oils in food preparation, often due to high pricing. It is light-coloured and delicate in flavour and scent, with a nutty quality.[4] Although chefs sometimes use walnut oil for pan frying, most avoid walnut oil for high temperature cooking because heating tends to reduce the oil's flavour and produce a slight bitterness. Walnut oil is preferred in cold dishes such as salad dressings.

There are two types of walnut oil commercially available: cold pressed and refined. Cold pressed walnut oil is typically more expensive due to the loss of a higher percentage of the oil. Refined walnut oil is expeller pressed and saturated with solvent to extract the highest percentage of oil available in the nut meat. The solvents are subsequently eliminated by heating the mixture to around 400 °F (200 °C). Both methods produce food grade culinary oils. Walnut oil, like all nut, seed and vegetable oils will undergo rancidification accelerated by heat, light, and oxygen.

qifeng machinery co supply two ways to solve the walnut oil pressing. one is hydraulic oil expeller and its featur is cold pressing without any heating, nutrition complete kept, healthy and safe, small processing quantity, from 35kgs/h to 100kgs/h, combined oil presser set or oil expellers set can supply 300-1000kgs/h processing quantity, which is good for commerical use or small business or homebusiness use, also for home use. oil expeller set as following picture:
 

automatic materials distribution to each oil expeller, and every machine works separatly, working/pressing time for each model is from 8 minutes to 18 minute per batch, so one work can serve four or more machines at same time.
another way is using screw oil presser to process the walnut, big processing capacity, quick easily and low cake/residual oil content, of ourse, the working temperature is +20'C under room temperature, all spare parts that touch the walnut and oil are stainless steel or alloy steel, whcih can keep the oil safe and health. of course screw oil press can also work as a combined oil press set, which can enhance the automatic grade and bigger process capacity, actrually most oil factories use this for their production, check our machines that applied in our customer's factory:

 

product manual:

(1). Overview:

80-type screw press is the development and production of small screw press, the model superior performance, low residual oil, long working life, the price is reasonable, a wide range of presses.

(2) working methods:

The machine can be used with a variety of steamed wok, frying machine and puffing machine for cooked, but also according to user needs, will clean up the material directly into the oil press to squeeze.

(3) Features:

1. Wearing parts using high-quality steel carburizing heat treatment to extend the service life, reducing the user cost and maintenance time.

2. Reasonable press chamber design, improve the efficiency of the oil.

3. Improve the factory before grinding, testing procedures, automatic commercial palm sunflower avocado olive black hemp seed coconut peanut cold screw oil press machine,improve the ease of use of the press.

(4) working principle:

When the oil press is running, the treated material enters the squeegee from the hopper. In the rotation of the squeeze spindles, the material embryo continues to push forward, the squeeze out of the oil. On the one hand, the diameter of the root axis of the screw shaft is gradually thickened and the pitch is gradually reduced. automatic commercial palm sunflower avocado olive black hemp seed coconut peanut cold screw oil press machine,As the material progresses in the press chamber, the volume is continuously compressed and the pressure is continuously increased to meet the pressure required for the precipitation of the grease. On the other hand, since the material embryo is constantly moving in the press chamber of the press, there is a great friction resistance between the material embryo and the squeegee, the material embryo and the press chamber at the same time Thread so that the material embryo forward in the forward at the same time, constantly outward flip, close to the surface of the screw thread surface layer can also rotate with the shaft, so that in the press chamber of each embryo particles are not equal speed, with the direction of movement ,automatic commercial palm sunflower avocado olive black hemp seed coconut peanut cold screw oil press machine, But also between the particles there is relative movement. The heat generated by the movement also satisfies the heat necessary for the oil extraction process to help promote the thermal denaturation of the protein in the embryo, destroying the colloid, increasing the plasticity, reducing the viscosity of the grease, making it easy to precipitate, thus increasing the The oil ratio of the oil press.
