Nut Roasters

A Nut Roaster is a food processing system that roasts different types of nuts to improve the taste and texture. Commercial nut roasters are larger, usually continuous, systems that can produce roasted nuts quickly and hygienically for customer’s consumption. These can be ready-to-run or custom-made to the clients’s production needs. Nut roasters can be built for continuous processing with a conveyor belt that pulls the nuts through the roasting tunnel at different speeds, exposing it to pre-programmed heat settings. It can also be a batch processing nut roaster that uses trays and trolleys rather than a conveyor belt. Other additional features that can be attached to nut roasters including feed devices, flavour adding systems, conveyor hoists, packaging systems, tumble drum seasoner and more.

Process Systems Services Pty Ltd builds customised roasting tunnels using steel conveyor belts, for a range of nuts. They can also supply parts to oven manufacturers, such as conveyor sections, steel belts, drive and tail terminals.

Roasting Nuts

Nuts are a healthy option for snacks as most are low in starch, high in protein, fiber and Omega-3 oils. Due to this nutrient make-up, nuts are relatively slowly digested, which means they are a good source of long-lasting energy. While roasting does not significantly affect the nutrients in most nuts, it does add to their flavour and makes them crunchier. Nuts can also be dry roasted (without oil) or toasted (heated in a heavy skillet on a stove top for about 10-15min).

Conventional nut roasting involves removing the shells and skins of the nuts before heating them. They are tossed in vegetable oil (about 2 tablespoons per cup of nuts), placed on a baking sheet sprayed with non-stick spray, sprinkled with salt, then roasted in the oven between 5 to 20 minutes. Once the nuts are slightly browned and fragrant, they should be removed from the oven.

Steel Belts

Steel belts are used by Process Systems Pty Ltd in many of their conveyor systems because they are easy to clean and maintain, which is essential for most industries but especially for food processing. Steel is an alloy of iron and other elements, depending on the properties that are required. Changing the type of elements used in the alloy can affect the grade of castability, tensile strength, ductility and hardness. Common elements that are combined with iron include manganese, chromium, vanadium and tungsten.

Steel belts are used in two main classes of industrial applications- general material handling and bulk material handling. For example, general material handling could include moving boxes along inside a factory. By contrast, bulk material handling may be used to transport materials in outdoor locations, whether agricultural products (e.g. wheat, cotton) or industrial products (e.g. coal, iron ore).

Process Systems uses steel belts in industrial process systems such as cooling tunnels, roasting tunnels, industrial ovens, driers, oil skimmers and trim removal.

Conveyor Systems

Conveyor systems are used in industrial applications to save labour and time transporting materials, conveying them from one place to another in a safe and efficient manner. Conveyor systems are used in a variety of industries, such as computer and electronics assembly, pharmaceutical production, bottling and food processing. Conveyor systems are also used for transporting people, such as escalators and passenger conveyor systems found in airports and train stations.

Conveyor systems can be hydraulic, mechanical or fully automated, with conveyor belts made out of steel, rubber or plastic. Conveyor belts are usually made up of one or more layers of material- an under layer called the carcass and an over layer called the cover. The materials that are used usually depend on what the conveyor belt will be used for. For example, food processing lines need systems that will be hygienic and easily cleaned, so steel belts are used.
