The new rust removal technology empowers Doing’s equipment to a higher level!

 

Good news! After the meticulous research and many tests of the professional technical team of DOING GROUP, the new rust removal technology has finally been successfully empowered, making the equipment manufactured by DOING achieve new upgrades of equipment anti-corrosion performance and stable performance. The price/performance ratio of the equipment is up to the next level!

In the equipment manufacturing process, the surface treatment of the steel raw materials is one of the key factors that determine the service life of the equipment. In order to make the surface of steel raw materials have good cleanliness and roughness, it is necessary to carry out pretreatment especially rust removal on the surface of the steel.

 

DOING's latest new rust removal process can not only remove the rust, oxide scale and welding slag on the surface of the steel raw materials, but also eliminate the welding stress of steel. This improves the fatigue strength of the steel raw materials, increases the paint film adhesion when the equipment is painted, and achieves the purpose of improving the corrosion resistance and the internal quality of the equipment.

DOING GROUP has always been adhering to the concept of "Quality&Customer first", constantly carrying out technological innovation and providing customers with high-quality equipment to help customers get more profits.

Our company's equipment is mainly divided into four major sections: energy recycling equipment, metal plastic separation and recycling equipment, starch and flour processing equipment, or edible oil processing equipment. No matter which sector you want to invest in, DOING can customize the equipment of suitable scale for you. Welcome to contact us for free quotation or visit the factory and test equipment with materials!

Peanut Oil Manufacturing Process

Main machines of peanut oil manufacturing process

Peanut Cleaning

Screening machine, de-stone machine and magnetic separator are the common cleaning machine for pre-treatment of peanut in oil extraction plant. They are adopted to remove certain impurities such as sand, stone, and metal, so that to improve the oil yield and production efficiency, and reduce wear rate of accessories. The immature, mildewed and broken peanuts should also be separated by the grading screen, which can be used to produce second grade peanut oil or be sold separately.

Husking

Husking machine is needed to remove the shells.

Crushing

Groundnut can be pressed as whole seeds in peanut oil making machine. But after crushing and flaking by use of roll crusher and flaking machine, the oil yield can be significantly increased. During the crushing process, the red skin of peanuts can be separated by wind selector, and to be used as raw material for medicine and chemical industry.

Flaking

The flaking machine is ued to flake the fruits, so as to make the peanuts reach the beast state before being pressed.

Cooking / Steaming

Roasting temperature is the key factor to produce peanut oil with fragrance. Too low, the fragrance will be weak, too high, it is easy to burn. In most situation, 180℃~200℃ is suitable. In order to prevent over cooked, the seeds should be cooled immediately, and then be crushed in toothed roller crusher.

Oil Pressing Process

Screw type peanut oil making machine is used in this process. Pressing temperature: 135℃; Moisture content 1.5%~2%. The residual oil rate can be reduced to 2% with twice pressing process. The crude peanut oil will be filtered by plate and frame filter, and then be sent to the refining machine. The oilcakes can be further processed in solvent extraction workshop to extract the residue oil, or be sold to feed mill plant. (Read more about defatted peanut flour production.

Peanut Oil Refinery

In some cases, the expeller pressed oil is required to be refined to produce high quality edible oil.
