津巴布韦采购需求：果蔬加工生产线、无菌灌装系统、机械设备

I'm looking for a detailed quotation for a complete plant design. The main components needed include a raw milk receiving and unloading unit equipped with a 500 L cooled tank and filtration system. Additionally, I require a pasteurization unit that can handle 300 L per batch, alongside a homogenization unit with a capacity of 300 LPH. Furthermore, the design should incorporate a cooling and holding unit to rapidly lower the milk temperature before packing, as well as a vertical sachet packing unit. The packing unit should feature a precise metering system that utilizes pump displacement or servo-controlled volume instead of relying on gravity flow. Your prompt response with the quotation would be greatly appreciated.
