Fruits and vegetables inherently have a limited shelf life. With the help of different techniques, these foods can be stored for longer periods of time. Examples of such techniques include cooking fruit to jams, blanching vegetables and fruit prior to freezing and/or jarring in glass or tin, and frying or deep-frying potatoes into fries or chips. Weighing equipment can optimize these processes. For example controlling the product supply in terms of weight (kg / s), controlling the cooking-, blanching-, baking and deep-frying processes, or by automating the fluid mix preparation, checking the filling processes and control weighing stocks items.
