Percolation extractor for high-volume vegetable protein extraction
Optimize extraction efficiency across diverse materials with a continuous-loop system designed for reliable high-volume processing, ensuring thorough solvent contact and rapid drainage for complete extraction performance.

Extracts Oils and Proteins from Diverse Materials
The Model III Percolation Extractor from Crown Iron Works is a continuous-loop, counter-current extractor designed for high-volume applications, such as processing vegetable proteins, oilseeds, and hemp CBD oil. This equipment stands out with its unique shallow-bed design, promoting optimal solvent contact and drainage, essential for complete extraction across a broad range of materials.
Utilizing a technology that allows both co-current and counter-current washes, it effectively maximizes the yield of products like soy protein isolate and essential oils. With an emphasis on energy and solvent efficiency, the Model III reduces solvent carryover, minimizing steam and hexane consumption during the desolventization process.
It supports ease of operation and maintenance, with self-cleaning screens ensuring longevity and reduced downtime. Particularly beneficial for industries ranging from nutraceuticals to biofuels, the extractor seamlessly integrates into existing production lines, offering PLC control for automated and high-capacity operations. The Model III is available with various material options to suit specific production needs, providing durability and compliance with industry standards.
