The BCC Liquid Separator – Efficient Seed Cleaning and Separation

The BCC Liquid Separator is a highly efficient solution designed for modern seed processing centers, offering reliable liquid separation for a wide range of seed species. The system is used as a continuous process to separate seeds, resin particles, and other impurities that resemble seeds in size and shape but differ in relative density.

Advanced Separation Process

The separation process is based on differences in buoyancy between good, mature seeds and defective material. Seed is manually fed into a hopper and vibrated into a mixing funnel where water (or another liquid) is added. The seed-liquid mixture is injected near the bottom of the tank to eliminate surface tension effects and improve separation efficiency.

In continuous operation, good seeds float to the surface and are transported via the overflow stream to a collection box. The system can also operate in batch mode when separating heavy seeds from lighter impurities. In this case, viable seeds are collected from the bottom of the tank at intervals.

Beyond separation, the process also provides a washing effect, removing dust and wing particles attached to the seeds.

Decreasing Resin Problems in Sowing

Growers can face recurring challenges with resin contamination in their seed lots. Resin particles can cause significant operational issues, as they may become lodged inside the sowing machine. In some cases, resin clumps are mistaken for seeds, causing the machine to sow resin into the growing containers. This can result in empty containers, uneven germination, and unnecessary time spent troubleshooting the sowing process.
