EVP-600 Vacuum Evaporator: How Solvent Recovery Works
The EVP-600 vacuum evaporator is the unit in a botanical extraction line that removes the solvent from the extract. It turns the liquid into a concentrated product such as concrete or absolute. Because it works at low pressure, the solvent evaporates at a lower temperature. As a result, the aroma stays safe, and the condenser […]
Rosa Damascena Processing Plant in Bulgaria: Rose Oil, Concrete and Absolute
A Rosa damascena processing plant must bring together every stage that makes rose oil, rose concrete and rose absolute. Flower reception, distillation, extraction, filtration, solvent recovery and storage all have to work as one system. The facility we delivered in Bulgaria shows this approach. It combines copper and stainless steel equipment, piping, platforms and support […]
Dual-Purpose Units: Running Extraction and Distillation on One System
A single stainless steel unit can be configured to run both solvent extraction and steam distillation, switching between processes through the valve and line arrangement. Here is how it works, where it makes sense, and where a dedicated line is the better investment.
Anchor Agitators in Stainless Steel Mixing Tanks: How They Work and When to Use Them
An anchor agitator sweeps the full tank wall at low speed, making it the right choice for viscous products and heated vessels. Here is how the design works, how it compares with turbine and propeller agitators, and how to specify one.
Why Precision Measurement Matters in Process Equipment Manufacturing
Precision measurement is one of the most important stages in the manufacturing and installation of industrial process equipment. Before a tank, extraction unit, distillation system, or process line becomes operational, its level, position, and connection points must be carefully checked. In this project, our craftsman is using a spirit level to verify the alignment of […]

How a rotating spherical extractor improves contact between botanical material and solvent, shortens cycle times and raises yield in essential oil production.
Phenyl Ethyl Alcohol Production Unit: Distillation and Recovery
Phenyl Ethyl Alcohol, also called 2-phenylethanol or PEA, is a valuable aroma compound. The fragrance, cosmetic, flavour and personal care industries use it widely. Because of its soft, rose-like scent, it appears in products from fine perfume to soap. A well designed Phenyl Ethyl Alcohol production unit turns the crude mixture into a pure, steady […]
Rosin Manufacturing Process: From Natural Pine Resin to Industrial Rosin
The rosin manufacturing process converts natural pine resin into two valuable products: rosin and turpentine oil. Manufacturers use these products in adhesives, paints, printing inks, rubber, paper and many other industries. Natural pine resin contains resin acids, turpentine, water and small impurities. Therefore, producers must heat, separate and filter the raw material carefully. In the […]
Absolute Extraction Unit: From Flower to Fragrance
Some of the world’s most precious natural fragrances—such as rose, jasmine, tuberose, and violet—are too delicate for steam distillation. High temperatures can damage their fragile aromatic molecules. Therefore, perfumers prefer absolute extraction to preserve the complete fragrance profile. At Dünder Makine, we combine more than 40 years of engineering experience with modern processing technology to […]
