Consulting, Custom Seed Processing, & Extraction


The tree seed extraction business is a specialty business that requires the operator to know some fundamental principles of seed biology and separation. The timing of every sequence in the process is important so that the seed product produced has a great degree of quality. Tree seed is a living organism that must be handled in certain ways. Tree seed extraction combines science and art along with the ability to pay strict attention to detail.


There are certain machines that are used in seed extraction that work well in a specific sequence of the operation. This is where the experience and engineering expertise of Jim Rockis could be invaluable to you. Give Jim a call to discuss these topics: (304) 282–3470.
