What does decorticator mean?
A decorticator is a device — occasionally a worker — that removes the tough outer covering, or cortical layer, of plant material. In agriculture it is best known as a machine that separates useful fibre or kernels from their husks, stalks, or shells: cotton decorticators strip lint-bearing material from plant stalks, hemp decorticators free long bast fibres from woody cores, and seed decorticators crack the hard coats of oilseeds and nuts. The word derives from the Latin cortex, meaning bark or rind, via decorticare, to strip of bark; the same root gives English 'cortex', as in the brain's outer layer. Decortication is thus the process, and the decorticator its instrument. The term belongs chiefly to technical registers — agricultural engineering, textiles, and food processing — and is seldom heard outside those fields, though it appears regularly in historical accounts of industrialised farming and fibre milling.
nounA person or, more commonly, a machine that removes the bark, husk, or outer covering from seeds, nuts, or plant fibres.
- A machine that removes the husk, hull, bark, or outer layer from seeds, nuts, or plant stems such as cotton and hemp.
- Rarely, a person whose job is to remove such outer coverings by hand.
"The cotton decorticator strips the fibre from the stalks before baling."
"The new decorticator doubled the mill's daily output of cleaned hemp fibre."
"Before mechanisation, each worker was essentially a human decorticator, stripping seed heads by hand."
Incorrect — the standard plural is 'decorticatators'.
From Latin cortex, meaning 'bark' — the same root that gives us 'cortex' for the brain's wrinkled outer layer, a decorticator literally 'un-barks' your cotton and hemp.

Etymology of decorticator
Decorticator comes from the Latin verb decorticare, formed from de- ('removal') plus cortex ('bark' or 'rind'), so it literally means 'one who strips off bark'. The noun was coined in English during the nineteenth century, when industrial machinery for processing cotton, hemp, and oilseeds made such an agent word practical. It shares the root cortex with cognates such as 'cortical', 'cork' (via Latin corticem), and 'decorticate'.
