The given diagram illustrates the process of producing raisins from fresh grapes and distributing them to various markets.
Overall, it is clear that there are seven distinct stages in raisin production, beginning with collecting grapes and ending with their distribution to grocery stores, commercial bakeries, and overseas markets. Notably, the drying process is the only stage that presents a specific period of time, which is two to three weeks.
Looking at the diagram more closely, one can see that the fresh grapes are harvested and dried under the sunlight for two to three weeks continuously. At the next stage, the raisins are transported to a processing factory, where they undergo further processing. The next stage involves cleaning the dried grapes to eliminate impurities, followed by washing them thoroughly.
Subsequently, the raisins are divided into two categories according to their size, namely larger and smaller ones. In the final step of this process, the products are packed before being supplied to grocery stores and commercial bakeries, while some are exported abroad.
