加纳采购需求：面粉厂、碾米厂、脱粒机、铡草机、其他农用设备、配件

We're looking to invest in rice milling equipment that can handle around 500 bags (50kg each) monthly. The machinery needs to effectively remove husks, stones, and insects, and categorize the output into three distinct types: whole rice, broken rice, and residues (including impurities). Please share info on suitable starter equipment for our needs, including its capacity, specifications, and pricing. We want to ensure top quality in our output, so detailed options would be great!
