Olive Pomace Pellet Machine & Pellet Plant

Applications Of Olive Pomace Pellet Machine & Pellet Plant

Olive pomace is a valuable by-product extracted from olive oil, it is a thick sludge, the main residue of the olive oil extraction process. It is the remaining pulpy material after removing most of the oil from the olive paste and it consists of pieces of skin, pulp, stone, and olive kernel. It still contains a certain amount of oil and water, and is used in the production of solid fuel, animal feed, composite fertilizer and olive pomace oil.

The olive pomace pelleting process is economic and efficient with robust RICHI olive pomace pellet making machines. Olive pomace pellet, which is generally produced in the form of small cylinders with a length of 1-3 cm and a diameter of 6-10 mm, contains less moisture than dried olive pomace and adapts better to existing solid fuel systems.

Although not common in many countries, in Italy and Spain, olive pomace is mixed with various biomasses and used as fireplace fuel. A 1-kilogram olive pomace briquet can burn efficiently for approximately 1 hour.

Olive pomace is used as solid fuel in pellet form especially in the Aegean region. It is preferred because it is ecological, contains 5000 kcal/kg, is affordable, and is low in ash compared to other fuels such as coal. There are exclusive boilers for olive pomace pellets.

Distribution Of Olive Pomace

Olive pomace is sourced basically from the areas with large olive tree plantation and a well-established olive oil industry. Olive is the most widely cultivated fruit crops in the world with a cultivation area of more than 10 million ha worldwide, and 95% of world’s olives are produced in the Mediterranean region. Most countries along the Mediterranean Sea produce olive oil in varying quantities. Spain, Italy, and Greece represent more than three-fourths of the total olive oil output in the world.

Since 2014, Spain Olives Production rose 15% year on year. In 2019, the country was ranked number 1 among other countries in Olives Production with 9,176,929 Metric Tons. Italy, Turkey and Greece respectively ranked number 2, 3 and 4 in this ranking. Slovenia witnessed the best average annual growth at +33.6% per year, while Iraq was the worst growing country at -18.2% per year.

Benefits Of Olive Pomace Pellet Made By Olive Pomace Pellet Machine

• The product is oil-bearing and is therefore water repellent on storage and contains less dust;
• A much better combustion value compared to wood pellets;
• The ash of olive burning has no disposal rights and is therefore suitable for spreading over the crops or the land as fertilizer because of its purity;
• Olive pellets and olive cake are available throughout the year with residue from production;
• No burden on the environment by cutting down trees;
• A higher and better CO2 compensation.

Uses of olive pomace pellets

• Nutshell pellet stoves
• Boilers with stoker
• Chicken farms
• Bread ovens
• All areas where coal is used.

Working Principle Of Olive Pomace Pellet Machine & Pellet Plant

The olive pomace pellet press machine process: crushed olive pomace material is fed evenly by the forced feeding device, the centrifugal force generated by the rotation of the ring die, and the action of the feeding scraper. The two pressing areas in the ring die are in the wedge-shaped space formed by the two press rollers and the ring die.

Under the strong squeezing action of the ring die and the press roller, the olive pomace material is gradually compacted, squeezed into the die hole of the ring die and shaped in the die hole. Because the extrusion of the material between the die and the roller is continuous, the formed olive pomace material is continuously discharged from the die hole in a columnar shape, and then cut into olive pomace pellets of the required length by the cutter, and then enters the next process.
