A Cooker Conditioner is vital to the pretreatment of some oilseeds. It consists of heating the seed and reducing the moisture content. The cooking operation is usually carried out in a stacked cooker, a vertical design where the seed moves down through steam-heated trays, each with its own stirrer system mounted on a common vertical shaft. It is designed for the cooking and/or conditioning of oilseeds during the preparation process previous to the mechanical pressing or flaking. The Cooker Conditioner utilize heat transfer from steam heated decks to heat the material. They are very useful and made for industries.
