A research team led by Choe Kyong Hyok, a researcher at the Faculty of Mechanical Science and Technology, has newly built an automatic frozen fish block packaging machine to ensure convenient packaging processes and higher productivity.
This machine is for wrapping in thin films frozen fish blocks entering through a thawing machine before storing.
The machine consists of a feeding conveyer, a longitudinal packaging conveyer, a lateral packaging conveyer, a longitudinal adherer, a lateral adherer and a film feeding system.
This machine keeps its feeding velocity at 0.5m/s in order to eliminate inertia of each 10-kilogram frozen fish block when they are stopped.
First of all, each frozen fish block entering through the thawing machine is fed to the feeding conveyer from the longitudinal direction. Each frozen fish block coming out from the feeding conveyer is fed to the longitudinal packaging conveyer pushing a vinyl film linked from top to down. When each frozen fish block is located in place, the longitudinal packaging conveyer is stopped and the longitudinal adherer works for packaging. This time the proximity detector detects the correct position of frozen fish blocks to ensure perfect joint.
Then, the longitudinal packaging conveyer starts up to move the blocks to the lateral packaging conveyer. The same process takes place for lateral packaging.
Finally, the blocks are forwarded through the lateral package conveyer to the transshipping device.
The productivity of this packaging machine is 900 blocks per hour, the output of the conveyer motor is 0.37kW and the reduction ratio is 15.
The packaging machine will find wide application at fisheries for automatically packaging 10-kilogram frozen fish blocks, and for making storage, transportation and supply of them convenient and clean.
