| 1 | Theeggs were then subjected to the negative pressure/imaging system and regraded. | |
| 2 | A vacuum pump creates negative pressure for correct operation of the filtrate recovery system. | |
| 3 | Vacuum suction and negative pressure strong force massage may directly explode thick fat. | |
| 4 | A tube fed through a small hole in the plastic connected to the pump, which was manually compressed to create negative pressure. | |
| 5 | The detection systemcould not press or squeeze the egg like the graders did, but what would happenif they could pull on the egg with a slight negative pressure, or vacuum? |
