赞比亚采购需求：果蔬加工生产线、无菌灌装系统、机械设备

We are looking for cost estimates on several machines to enhance our processing capabilities. Specifically, we need an industrial washing, peeling, cutting, and slicing machine, along with a vacuum packaging unit, to handle 3-6 tons of sweet potatoes and butternut squash daily. Additionally, we're interested in equipment for tomato paste production, including an industrial crusher and pulper, an evaporation system, and filling and sealing machines for processing 2-4 tons per day. Moreover, we also require equipment for watermelon juice and pulp processing. This includes a juice extractor, peeling unit, filtration system, and a pasteurization setup to meet our production needs. Please provide detailed pricing and specifications for the aforementioned items, as we aim to enhance our production efficiency.
