Final answer:
Typically, foods containing both solids and fluids are sterilized by heating the components together and cooling using conventional equipment. While the 'Jupiter System' isn't a recognized term in sterilization, the general practice aligns with option 4.
Step-by-step explanation:
The question concerns the sterilization of foods, particularly those containing particulate solids, in what is referred to as the Jupiter System. While the Jupiter System is not a widely recognized term and no specific information on the Jupiter System for sterilizing foods was provided, the answer can be inferred using general knowledge of sterilization methods. In typical sterilization processes, especially with foods containing both solid and fluid components, those components are generally heated together to ensure uniform sterilization. For cooling, conventional fluid heating and cooling equipment may be utilized. Hence, the closest answer to the provided question, based on common practices of sterilization, would be that both solids and fluid components are heated together and cooled using conventional fluid heating and cooling equipment.
