Cold&Hot press groundnut oil expeller machine with advanced oil making technonogy

   Our Multifunctional Cold&Hot press groundnut oil expeller machine for different oil seeds is kind of newly  cold&hot temperature screw oil press with multifunction is a new research improvement product. it can use to press rapeseed,peanuts,soybean, sesame,sunflowerseed,grape seed and other plant oil materialas. this kind of machine adopts micro-electrical control,filter system, muti-stage press and can hot press. the product oil is the clean oil after filtering,it can directly to use.

   Our Multifunctional Cold&Hot press groundnut oil expeller machine for more than 20 kinds of different oil seeds  such as Rapeseed , Peanut /groundnut, Sesame, Soybean, Tea seed, Flax seed, Cotton seed, Sunflower seeds, walnut, Black sesame, Almond, Basil, Pinenut, Palm kernel, Coconut meant, Pumpkin seed, Grape seed, Corn germ, Mustard seed,etc.

Cold&Hot press groundnut oil expeller machine 

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.

Cold&Hot press groundnut oil expeller machine 

The high efficiency energy saving oil press machine of our company is designed with advanced

 technology, reliable performance,  easy operation, easy of maintenance, the main features of the

 machine are below:

1. High oil extraction rate: compared with traditional equipment, its normal oil extraction rate can be

 1-2% higher, can press out 1-1.5 kg more each 50 kg on average,so the economic benefit of full

 year is very appreciable.

2.  Energy saving:under the same capacity,the power is 40% lower,6 KWH energy saving per hour.

3.  Labor saving:Under the same capacity, it is 60% labor saving, to be able to organize manufacture

 by 1-2 persons.

4. Widely application: Multifunction, can be used for processing Peanuts, sesame, tea seed, palm, 

sesame, rapeseed, canopy, cottonseed, soybean, etc. more than 20 oil crops. 3 level press technology,

oil can be squeeze out completely only once.

5. Oil is pure:use vacuum filter filtering residue. Ensure the oil purity,  and confirm to Health and 

Sanitary Regulation.

6. Less occupied area: the space of 10-20 square meters can meet the requirement.

Yield of oil output for main raw seeds:

1. Delivery time.
   ---5-10 days after order confirmation. We need time to prepare machine according to exporting standard, wear-in, making wooden box, fumigation and suitable ship arrangement from forwarder.
2. If I don't know how to operate this machine? how can I do?
   ----Our machine has been tested OK and fully assembled before shipping, customer just needs to make
   2~4 hours wear-in and then can work.
3. What's wear-in for new machine?
   ---- use 10 KG oil cake + 1KG sand + 1KG water, mix them, put in oil press, wear in 3~4hs.
   1st hour, adjust oil cake thickness as 3mm.
   2nd hour, adjust oil cake thickness as 2.5mm.
   3rd hour, adjust oil cake thickness as mm.
4. What are cold press and hot press?
   ----Cold press is pressing dry and raw seeds. Usually need to press 2 times to get maximum oil.
   ----Hot press is pressing roasted seeds. Usually only press 1 time to get maximum oil. peanuts roast
   to 125~130 degree with 1~2% moisture. (We produce seeds roaster heated by economical fuel.)
