Application

Almond (Prunus dulcis) is a tree from the Rosaceae family that grown for its edible seeds or nuts. Almond trees originated from Central and Southwest Asia. This edible nut has a bright white colour that is wrapped in a reddish brown cover seed coat. Almonds are divided into two varieties, sweet almond (Prunus dulcis variety dulcis) and bitter almond (Prunus dulcis variety amara). Generally, sweet almonds are usually used for consumed as nuts and used in cooking, while the bitter almond is usually extracted for manufacturing foods and liqueurs. As consumption, almond could be eaten raw, blanched, or roasted, and commonly used in confectionery baking.
 

Manufacturing Process

Almonds are commonly distributed in dry nuts form. The post harvesting process and finish processing of almonds are:

Harvesting

Typically almond harvesting begins in August. Although the beginning and duration of harvesting season vary based on the weather and the size of the crop. Almonds could be harvested by knocking the nuts from the tree limbs with a long pole or mechanically.

Stockpiling

Stockpiling is the process where nuts are swept into rows to be collected and stockpiled while waiting to be hulled and shelled. In this process, the almond will be dried on the orchard floor for 7-10 days. This is a critical stage of the almond post-harvest process, because in stockpiling almond are prone to pest attack. 

Hulled and Shelled

Almonds then continue to be hulled and shelled in the factory. Hulling is the process where almond are hulled to remove the hull leaving the in-shell nut and also helps remove twigs and foreign matter coming from the fields. There are two types of huller: hulling cylinders (for wetter hulls) and shear rolls (only for dry hulls and better for removing tight hulls). For shelling, shear cracking rolls could be used. However, in these processes up to 30% of the kernels could suffer damage more such as scratching, chipping, or breaking. To avoid such damage the factors that should be considered are: roller speed differential, almond orientation, roller’s clearance.

Screenings

After shelled, almond then continued to a series of vibrating screens and aspirators. This process helps to separate hulls, unhulled, in-shell, and shelled nuts and fine debris. The unhulled and in-shell nuts will pass through huller and sheller again. The kernels then undergo further cleaning and grading process. After that kernels will went through screening and aspirators again.

Packaging

Almonds that are sent through screenings can be packaged or sent through further processing such as roasted, diced, salted, or other processes to change the final product.

 

Commonly, almon is used for cooking ingredients or raw consumption. Almonds could be eaten raw or processed into butter, flour, extract oil, paste, syrup, and milk. The uses of almond is based to their variety. Sweet almonds are usually consumed as nuts and used in cooking, while the bitter almond is usually extracted for manufacturing foods and liqueurs. As consumption, almond could be eaten raw, blanched, or roasted, and commonly used in confectionery baking.

Categorization

Almond kernels are categorized as nuts. Although, almond kernel is precisely a nut-like kernel.
