Abstract
A commodity densification and storage assembly has a housing having an insert port for receiving a commodity, such as aluminum cans, glass bottles, and PET bottles. The assembly further includes a device for densifying the commodity oriented downstream of the insert port; a storage device for storing the densified commodity; and a pneumatic device for conveying the densified commodity to the storage device. The pneumatic device includes an inlet pipe for receiving the densified commodity from the densifying device. The inlet pipe is in communication with the storage device. The pneumatic device further has a blower for creating suction and an outlet pipe in communication with the storage device and the blower. The blower draws the densified commodity to the storage device through the inlet pipe via suction. Additionally, the pneumatic device includes an air filter system for preventing densified commodity from entering the blower. The filter system includes a cartridge filter and a device for storing and delivering fluid under pressure. The blower draws air that passes in sequence through the inlet pipe, through the storage device, through a primary filter, and through the cartridg…
