Stainless Steel Line Vac Conveys Egg Shells from Harvester to Waste Bin

IMG_0787

Our customer has a process where they de-cap eggs which are used in a variety of processes ranging from large scale bakery uses to medical uses for developing vaccines. The problem is they are left with a reasonable amount of egg shell waste that needs to be cleaned up after each cycle in the de-capping process. The previous method relied simply on friction and gravity to get the egg shell to go into the direction the customer wanted.

The problem with this method is that reliability was quite low. Egg shell would remain inside the egg, inside the tooling and pretty much everywhere around the de-capping process. The customer wanted to clean things up in the process a bit and increase the reliability that the shells go where they want them to which is a waste container about 5 meters away from the de-capper. The rate of shell flow was about 20 kilos per hour.

The customer made a search on the Internet for Air Vacuum conveyors and found EXAIR Corporation. After a short discussion to find out the specifics concerning rate of flow, distance, density of the product and available air pressure, we were able to make a suitable recommendation.

We ended up recommending EXAIR Model 6963 (1-1/2” Stainless Steel Line Vac kit). Having the full kit available allows the customer to install the Line Vac using included bracket for mounting as well as the air filter/separator and compressed air regulator with gauge to allow for accurate tuning of the air pressure to get just the right amount of suction from the Line Vac unit.

The customer purchased the recommended kit and installed on their machine. They have claimed the reliability has gotten to the point where the problem has nearly gone away. They still had some issues with the blades used, which they intend to sort out as a next step in their process of continuous improvement.
