Pinenuts Processing Equipment

Pinenuts Dehulling & Separating

Functions and Features:

Pinenuts dehulling and separating equipment is our company’s patented product with independent intellectual property. It is an original technology, which can be used to size, dehull and separate. Meanwhile, the un-hulled seeds will go back to the dehullers for automatic re-hulling.

The pinenut dehuller combines the friction and impacting force perfectly to achieve high dehulling efficiency and meanwhile the broken rate is greatly reduced. The rollers inside the dehullers can be adjusted according to different size of pinenuts, thus the dehulling rate is increased and broken rate is reduced at the same time.  We also adopt the best performance positive-pressure combo gravity-separator to separate the pine kernels from the shells. It features easy operation, a high degree of automation, is safe and reliable, and a beautiful and durable extensive application.


The sizing unit consist of input hopper, elevator and sizing machine.  The dehulling unit consists of input hopper, elevator, dehullers (it varies with different kinds of pinenuts), separating screen, and a laminated spring plate conveyor.  The shell removing unit consists of input hopper, spiral elevator, shell-kernels separator and twin-outlet elevator.
