EXTRACTION UNIT

PAR TEK is always one step ahead of its competitors and shows its difference to its customers with its technology developed by adopting the idea of minimum solvent (hexane) loss and degreased pulp in accordance with world standards in    extraction systems.

Advantages offered by PAR TEK Extraction Process;

  • Good quality oil removed from solvent,

  • Minimum solvent (hexane) loss,

  • Pulp with low oil content,

  • Low solvent and energy consumption,

  • Process with low operating cost and minimum losses,

  • Facilitates oil separation from Misella,

  • It offers automatic control panel with PLC system and minimum labor

Continuous Extractors

The operating principle of continuous extractors, which have low operating costs and automation, is based on the comparison  of seed flakes with the highest oil content with mycelium  with the highest oil concentration (counter current). Thus, the pulp, whose oil content reaches the lowest value, is washed with pure solvent for the last time and the extraction process is completed.

In PAR TEK continuous extractors, with the bucket chamber and two-layer system, the cake is washed with solvent to obtain maximum oil, and cleaner pulp is obtained by colliding pure solvent (hexane) with minimum oil cake with the countercurrent principle.

PAR TEK Continuous Extractor Advantages;

  • With the stainless V sieve, the problem of clogging is eliminated,

  • Easy maintenance and working principle,

  • Low operating cost,

  • Minimum loss,

  • Sprayers developed for uniform micella distribution,

  • The use of stainless materials in areas in contact with solvent (hexane),

  • Low leakage    risk      with      durability   and     quality workmanship,

  • A good filtering is obtained as the product is broken down while passing from the upper floor to the lower

Toaster

Recovery of the solvent (hexane) in the pulp leaving the extractor; the pulp obtained as a result of the extraction process has 30-35% solvent (hexane). A system called toaster is used to separate the solvent from the pulp. During the removal of the solvent (hexane), which is a heat treatment before the drying and cooling process of the pulp, it is also possible to increase the quality of the pulp by fulfilling the dispersion ability of the proteins and the solubility of the nitrogen in the protein structure in water.

Advantages of the PAR TEK Toaster;

  • Provides maximum solvent (hexane) recovery in their designs,

  • The pulp from the toaster outlet  is obtained without any problems for animal feed and similar uses in accordance with world  standards,

  • Level control to adjust product height and quantity,

  • The use of stainless materials in areas in contact with solvent  (hexane),

  • Longevity,

  • Quality and exquisite

  • Specially designed coupling with high temperature resistance, working well in all operating conditions

  • High vapor density allows  the steam to sufficiently separate the solvent from all pulp  particles

Removal of Solvent from Miscella

The process of removing the solvent from the micella

includes many steps such as filtration, distillation, and removal of the remaining solvent by steam distillation of the micella.

​

Filtration of Micelle

In addition to the crude oil quality, the micelles must be filtered in order to facilitate the circulation of the oil in the system during the distillation process and to eliminate the resistance that the seed flakes may form against heat transfer.

​

Distillation of Micella

Generally, solvent evaporation is carried out in two or three stages. In the pre-evaporation process, which constitutes  the first stage, the filtered micella is heated to the boiling point with indirect steam in a heat exchanger and most of the solvent is evaporated. In the second stage, the oil concentration is increased by heating the miscella again with the help of a heat exchanger until its boiling point. Vacuum in the system is usually provided by single or two-stage steam jet ejectors. In the final stage of solvent recovery, the remaining solvent is removed from the oil by direct steam injection. This process, which is defined as steam distillation, is carried out in packed columns. The crude oil obtained is given to the vacuum dryer placed at the bottom of the package column, dried under pressure and sent to the crude oil tanks.

​

Distinguishing Features of PAR TEK Distillation Column;

  • Compared to its competitors, 2 columns are used for safety,

  • The old type rashing ring system was removed due to the difficulty of cleaning, and a bowl type column was designed

  • Solvent (hexane) separation with low steam consumption,

  • High efficiency in the separation of solvent (hexane).​

 

Absorption System

It is the system used to recover the solvent (Hexane) gas that is evaporated and escaped in the extraction system by condensing. Then physically separate the liquid water and the solvent (hexane). Afterwards, the solvent (hexane) can be sent to the hexane-water separator and the wastewater can be safely discharged from the plant.

 

PAR TEK designs solvent (hexane) recovery equipment to achieve maximum efficiency and provides services with its experienced engineering staff in this field.

With the PAR TEK Absorption system,

  • Maximum solvent (hexane) recovery is achieved,

  • Operating costs are kept at a
