Prodn. of oiled and salted roasted peanuts etc. - which are clean dry baked then cooled before oiling and salting

摘要

In baking, the nuts are pref. spread in a thin layer or an oven tray or on a conveyor band or a continuous oven. The baking process pref. includes a progressive preheating stage in which the temp is raised from ambient to 120 degrees to 130 degrees C. The temp. is maintained at about 130 degrees to 140 degrees C for a time. Total baking time is pref. 15-20 minutes. The oven pref. comprises a cooling zone into which baked nuts are transferred for cooling to ambient temp. The cooking process can be carried out in an atmos. of hot, inert gas. The oil is not subjected to thermal shock, thus avoiding unpleasant flavours, and reduced oil contents of the prod. The coating oil has a higher resistance to oxidn. so the shelf life of the prod. is extended. The baking process is cleaner and more hygienic than when nuts are preheated in oil.
