OS-451
Automatic Rotary Type Roasting Oven

This standard guided roasting machine is an upgrade to traditional guided ovens and earlier single-stage track roasters. Designed specifically for drying and roasting nuts and seeds, it is equipped with a single two-stage burner that ensures low NOx emissions, delivering exceptional roasting quality and superior taste. Engineered to maintain the full aroma and flavour profile of the product even under high-temperature conditions, it uses the hot-air roasting method. With two baskets (one perforated and one non-perforated), the machine facilitates the discharge of the finished product by inserting the basket towards the centre of the drum. Furthermore, the machine supports salt roasting, whereby the salt acts as an indirect heat medium to protect the product from centrifugal force damage; the finished product is then removed using the perforated basket.

Frequently Asked Questions

The OS-451 belongs to the rotary roasting oven range, which is designed for drying and roasting nuts and seeds using hot-air roasting, a single two-stage low-NOx burner and two baskets for discharge. Capacity, dimensions and energy figures are not published for this model, so the exact configuration is confirmed during project evaluation.

Start with the products you roast, the hourly output needed for each, the available fuel and the installation space. Capacities differ by product, so compare them for your main product rather than relying on a single figure. The final selection is confirmed for the intended application.

Ovens in this range support salt roasting, where the salt acts as an indirect heat medium that helps protect the product from centrifugal force damage. The finished product is then removed using the perforated basket. Cleaning of the drum after salt roasting should be included in the production plan.

Depending on the operation, supporting equipment can include feeding systems, conveyors, cooling and packaging stages. The selection depends on the product, the output target and the factory layout, and is assessed with you during project evaluation.
