Technical Field
The invention relates to a conveying device for bulk material grain and a conveying system comprising such a conveying device.
Background
In practice, bulk grain is typically transported and supplied in bags. Bulk grain is packaged at the supplier, for example, 25kg per bag. This packaging operation at the supplier requires a certain cost. Some enterprises that utilize bulk grain for production require a large amount of bulk grain, such as flour. Therefore, in these enterprises, a large number of packaging bags need to be disassembled, and bulk grains contained in the packaging bags need to be dumped out. The process of unpacking a large number of packaging bags and dumping bulk grain from bag to bag is associated with production costs and implies higher time costs. In addition, the large number of unpacked packages not only increases the risk in terms of food safety, but also causes a burden on environmental protection.
