10-500tpd new technology groundnut oil manufactureing process with ISO9001:2000,BV,CE

Brief introduction of groundnut oil manufactureing process

1, pressing chamber pressure size range, good adjustable (0.1-150MPa);

2, can adapt to the process of various oil and various oil preparation, including cold pressing, hot pressing, high water slurry residue for oil and high oil content oilseed grinding pressure oil;

3, long production period, loading, unloading cake trouble, stand-alone production efficiency is low, equipment and large occupation area;

4, static squeezing out oil efficiency is low, the operation requirements "edge planing reconditioning, workshop insulation (35℃)," poor labor conditions. Therefore, this kind of oil equipment in general can only be used in some scattered oil (like rice bran) and the need to maintain the special flavour or nutritional (like cocoa beans, sesame) pulping hydraulic oil.

  Operation Principle of groundnut oil manufactureing process

1.When oil press is on work, material enters the extruding chamber from the hopper and then moves forwards by the rotating pressing screw and is pressed.

2.Under hightemperature condition in the chamber, there is quite strong friction among press screw, chamber and the oil materials.

3.On the other hand, root diameter of the pressing screw carries larger from one end to the other.

4.Hence when rotating, the thread not only pushes particles moving forwards but also turns them outwards as well.

5.Meanwhile, particles adjacent the screw will rotate along with screw’s rotating, causing every particle inside the chamber to possess different speed.

6.Therefore, relative movement among particles creates neat which is necessary during manufacturing because of helping protein change property, damage colloid, increase plasticity, decrease oil’s elasticity, resulting in high oil.

Technology process of groundnut oil manufactureing process

1. Cleaning

The de-ironing sunflower seed feed into single-deck screen clean sift for cleaning, large material expelled from discharge hole, and the bigger ones enter into grinder for smashing.

2. Cracking and flaking

Cleaned sunflower seeds enter into flaket from crusher which has two teeth roller with different speed .Then rolled into embryo under roller.

3. Cooking steaming process

Under cooking process, flakes come up complicated physical chemistry change, and the moisture and temperature of the materials can reach press term.

4. Pressing process

After reaching press term, The embryo enter into oil press for prepress. The dreg inclusion crude oil is pressed into settle oil tank through oil scraper blade.
