diagram for in-shell peanut processing. Processing begins with separating foreign material (primarily soil, vines, stems, and leaves) from the peanut pods using a series of screens and blowers. The pods are then washed in wet, coarse sand that removes stains and discoloration. The sand is then screened from the peanuts for reuse.

Also known as sand molding casting, sand casting is a casting-based manufacturing process that involves the use of a sand mold. It’s used to create metal products and components in a variety of sizes and shapes. To put its popularity into perspective, statistics show over half of all metal castings — about 60% — are produced using sand

(iii) Salt and sand. The density of salt and sand are different from each other. Sad is heavier than salt and has 2.65 g/cm 3 density. Therefore, by shaking the mixture of salt and sand, separation can be done. In this process, the salt will separate up and the sand being heavier will deposit down forming the layer.
