Complete Process of Tunisia Olive Pomace Oil Extraction and Refining Plant
Date:May 6th, 2026
Tunisia is a renowned global olive-producing country, with centuries of olive cultivation and processing history. A huge amount of olive pomace is generated every year after virgin olive oil pressing, forming abundant renewable raw material resources. However, due to unique raw material characteristics and technical limitations, most local pomace fails to achieve high-value utilization. This article comprehensively introduces the standard production process of a professional Tunisia olive pomace oil extraction and refining plant, analyzes common local technical pain points, and shares Dingsheng Machine’s optimized process solutions and standard factory configurations suitable for Tunisian investors.
Unique Characteristics of Tunisian Olive Pomace Raw Materials
Compared with olive pomace from other North African regions, Tunisian olive pomace has distinct processing characteristics. First, it features unstable acid values, affected by local climate, olive varieties and pressing cycles, with easy oxidation during storage. Second, the pomace contains high residual plant fibers, fine impurities and trace moisture, leading to easy mildew and deterioration if stored improperly. Third, the residual grease in Tunisian olive pomace is concentrated and viscous, making conventional extraction equipment unable to fully extract grease, resulting in low oil yield. These unique raw material traits put forward higher requirements for professional extraction and refining technology.
Standard Complete Process of Tunisia Olive Pomace Oil Plant
The mature olive pomace oil processing production line tailored for Tunisia adopts a complete industrial production flow: Raw Material Pretreatment → Solvent Extraction → Degumming → Deacidification → Decolorization → Deodorization, realizing full-process automated production from waste pomace to high-standard finished oil.
1. Olive Pomace Pretreatment
This is the basic core step to improve oil yield. The equipment screens, crushes, dries and adjusts moisture of raw olive pomace. It removes large impurities and mildewed materials, balances raw material humidity and particle fineness, and creates the best physical state for subsequent solvent extraction, avoiding incomplete grease extraction caused by raw material agglomeration.
2. Solvent Extraction
Adopting advanced rotary solvent extraction technology, the equipment fully contacts the pretreated olive pomace with solvent to efficiently dissolve residual grease. This step maximizes the recovery rate of pomace oil, greatly reduces residual oil in waste pomace, and solves the problem of low grease utilization rate of traditional manual and simple pressing methods.
3. Degumming
Remove colloidal impurities such as phospholipids and proteins in crude pomace oil. Colloids are the main cause of turbid oil and easy oxidation. Professional degumming treatment ensures clear and transparent crude oil and lays a foundation for subsequent fine refining.
4. Deacidification
Targeting the high acid value defect of Tunisian olive pomace crude oil, the deacidification process removes excess free fatty acids, effectively reduces oil acid value, and avoids oil deterioration and rancidity during storage.
5. Decolorization
Through physical adsorption and filtration, remove natural pigments, oxide impurities and suspended substances in crude oil, improve the transparency of pomace oil, and make the finished oil meet the appearance standard of commercial edible oil and industrial oil.
6. Deodorization
Adopting vacuum low-temperature deodorization technology, eliminate peculiar smell, greasy flavor and volatile oxidative substances in olive pomace oil. The final finished oil has pure flavor, stable quality and long shelf life, fully meeting local Tunisian standards and EU export qualification requirements.
Common Technical Difficulties in Tunisia Olive Pomace Processing Plants
Most local investors face multiple technical bottlenecks when building pomace oil factories. Firstly, unstable raw material quality leads to fluctuating oil yield, and ordinary equipment cannot adapt to variable acid value and impurity content of local pomace. Secondly, traditional processes easily cause oil oxidation and high acid value rebound, making finished oil fail to meet export standards. Thirdly, many small factories lack systematic refining technology, resulting in dark oil color and heavy peculiar smell, which cannot enter the high-end market. Fourthly, mismatched front and rear equipment leads to low overall production efficiency and serious raw material waste.
Dingsheng Machine’s Targeted Process Optimization Solutions
Aiming at the above common technical difficulties in Tunisia’s pomace oil processing industry, Dingsheng Machine has carried out targeted technical optimization based on local raw material characteristics. We adopt variable parameter adaptive extraction technology, which can adjust extraction temperature, time and solvent ratio according to different pomace quality, ensuring stable and high oil yield all year round. The optimized low-temperature refining process effectively suppresses oil secondary oxidation and acid value rebound, greatly improving finished oil stability.
In addition, our integrated degumming and deacidification system efficiently removes complex impurities unique to Tunisian pomace. The upgraded vacuum deodorization system completely eliminates peculiar smells without damaging oil nutrients. The whole production line achieves seamless docking of pretreatment, extraction and refining processes, solving the problem of mismatched process links and low production efficiency of traditional equipment.
30–100TPD Standard Factory Configuration Suitable for Tunisian Investors
Combined with the raw material output, factory scale and investment budget of most Tunisian olive processing enterprises, Dingsheng Machine recommends the most cost-effective 30TPD, 50TPD and 100TPD standard olive pomace oil extraction and refining complete lines, which are the most mainstream and profitable factory configurations in the Tunisian market.
30–50TPD Small and Medium-Sized Standard Plant: Suitable for local olive processing cooperatives and small and medium-sized factories. It features low initial investment, small floor space, simple operation and flexible production, perfectly matching the decentralized raw material supply characteristics of Tunisian rural olive planting areas.
100TPD Standard Large-Scale Plant: Suitable for large local processing enterprises and investors focusing on long-term export business. The fully continuous automated production line realizes large-scale, high-efficiency and low-consumption production, with higher oil yield and more stable finished oil quality, supporting long-term stable supply for EU export orders.
