How do they de shell sesame seeds?

Sesame seeds are de-hulled by a mechanical process involving several steps:

Harvesting: Sesame seeds are first harvested from the mature sesame plants. The plants are uprooted or cut, and the seed pods are collected.

Drying: The harvested sesame pods are then dried to reduce their moisture content and make them easier to process.

Threshing: The dried sesame pods are threshed to separate the seeds from the pods. This can be done using traditional methods like beating the pods with sticks or using modern threshing machines.

Winnowing: The threshed seeds are then winnowed to remove any remaining plant debris, dust, and chaff. Winnowing involves exposing the seeds to a stream of air, which carries away the lighter impurities while the heavier seeds fall to the ground.

De-hulling: The de-hulling process specifically removes the outer hull or husk of the sesame seeds. There are several methods used for de-hulling:

* Mechanical De-hulling: In this method, machines with rotating abrasive surfaces or rollers are used to rub the sesame seeds, gradually wearing away the hulls.

* Abrasive De-hulling: This involves passing the sesame seeds through a series of abrasive surfaces or screens to scrape off the hulls.

* Air-jet De-hulling: In this method, a high-velocity stream of air is used to impact the sesame seeds, causing the hulls to break and separate.

The de-hulled sesame seeds are then cleaned, sorted, and further processed depending on their intended use. Some may be roasted, ground into flour, used in cooking oils, or sold whole for various culinary applications.
