What is shelling?
It is the process by which the kernel or fruit is separated from the outer shell that protects it.
In addition, it is essential to minimize the breakage of the kernel throughout the whole process, especially at the moment when the outer shell is broken.
Phases of the shelling process
All stages of the shelling process are controlled according to certain parameters in order to optimize the process and obtain a final product of optimum quality.
Preparation
The almonds are conditioned before shelling to avoid undesired breakage of the kernel. To do this, the kernel must be processed at an appropriate humidity.
Shelling
This is the phase in which the outer shell is broken. The product is pre-calibrated for a better adjustment of the splitting hammer to the size of the product.
Separation
It consists of different machines and technologies, the main objective being the separation of the husk and the grain.
Drying
Due to the optimum working humidity for dehulling, a subsequent drying process is necessary to lower the humidity of the final product.
Cooling
The drying process is followed by cooling where the temperature of the product is reduced so that it can be stored correctly.
Selection
This is an electronic process in which any husk or impurity that may remain with the grain is almost completely eliminated.
Calibration
The fruits are separated by size through mechanical means.
