Process Flow

Fully automated process from start to finish

  • The product is preheater with warm air prior to being transferred to the pasteurization chamber

  • The ambient air inside the chamber is evacuated by pulling a vacuum, before injecting saturated steam. Due to the pressure difference the steam penetrates the entire surface of the product.

  • The warm product is transferred to the roasting platform, where hot air is pushed through the product to reach the desired homogeneous roasting.

  • The product is actively cooled with HEPA filtered air to a temperature suitable for further processing or packaging.
