Cashews have a delicate flavor that becomes more pronounced when roasted. The roasting process enhances the sweet, buttery, and nutty notes of the cashew through browning reactions and caramelization of the natural sugars. Gently heating the nuts brings out their aromatic oils, intensifying the overall cashew taste that is subtly delicious on its own.
To achieve an even roast, having the right equipment makes a difference. Ovens or professional roasting machines allow maintaining precise temperature control, but thick-bottomed pans on the stove-top also work. The nuts should be spread out in a single layer rather than piled up. Metal pans conduct heat more evenly than glass. Digital thermometers help monitor the interior nut temperature. Wire racks or perforated pans that promote air circulation roast faster than solid trays. Oiling the pans minimizes sticking but needs to be done lightly to avoid greasiness.
The first step is selecting raw cashews that are properly dried and have moisture content below 5%. Any pieces, splits or defective nuts should be removed. Keep the batch size optimal for the pan or oven so that the nuts are not crowded. Preheat the equipment to 180-190°F which is ideal for bringing out the flavors without burning the nuts. For stove-top roasting, use medium-low heat settings to gradually warm the pan through before adding nuts.
Once the cashews are layered out in the pre-heated equipment, roast by carefully stirring or shaking the pan every few minutes. This rotates the nuts for even exposure to the heat. Depending on whether a light, medium or dark roast is preferred, they need to be roasted for 8-15 minutes. Check frequently as they can quickly transition from golden brown through reddish tones when the sugars caramelize. Roast only up to the point where the cashews split slightly and white steam escapes. Immediately remove them from the heat source once done.
Visually, properly roasted cashews transition to a reddish brown color. Their surface skin flakes off easily when rubbed between the fingers. Drawing close, you will notice an enticing, nutty aroma when the oils are released during the roasting. Listening closely, light crackling sounds can be heard as well in the final stages. All these sensory signals combined indicate nicely roasted cashews ready for consumption.
After removal from the roasting equipment, nuts need to be spread on trays or racks to allow air circulation for quick cooling. This stops the cooking process so they do not get overdone. Cashews can then be selected for breaks, chips and irregularities which impacts taste and presentation. Store the roasted nuts in airtight containers to retain maximum crispy texture and prevent moisture absorption during storage.
Batch type drum roasters are commonly used for commercial production volumes of roasted cashews. In these machines, the metal drum rotates and tumbles the cashew batches while exposing them to adjustable heating mechanisms. Often heat is provided through gas flame burners heating the exterior drum surface.
The drums have varying holding capacities ranging from 20-100 pounds of nuts per batch. The continuous tumbling ensures uniform roasting. These industrial drums are generally made of stainless steel and digitally controlled for setting target temperatures and roast durations. Automated mechanisms unload the finished roasted cashews once a batch cycle completes.
Key benefits of batch drum roasters include their high productivity rate, consistency between batches and labor reduction compared to manual roasting. Their enclosed approach also helps collect any cashew oils released during the process. The closed drum shape allows rapid heat transfer improving energy efficiency as well. The batch quantities, flame heat intensity and cycle times can be customized to achieve light, medium or dark roasts as per requirements. These versatile industrial cashew roasters produce large volumes demanded commercially.
