The first step in every egg processing plant is to obtain as much as possible of the liquids within the eggs, separate the yolk from the white, and discard the shells. This is also the part of the plant that determines the kinds of products and the quality which you will be able to produce. These steps form the basis of any liquid egg processing plant. 8 9 De-Palletizer Full Automatic Unloading of Egg Stacks The De-Palletizer is a fully automatic robotic arm that gently unloads the egg stacks from the pallet to the infeed conveyor. The De-Palletizer handles plastic trays, interlayers, and pallets at a capacity of up to 216,000 eggs/hour (600 cases/hour). The system can be installed upstream of any kind of loader solution from one to two tray stack loading conveyors and from one to two full pallet positions. With the advanced vision system, the De-Palletizer automatically recognizes and compensates for pallet misalignment up to 100 mm. Four tray stacks at a time are picked up and then loaded onto a conveyor. If necessary, the tray stacks are synchronized with the loader inlet conveyor, depending on the loader brand. The full Gently unloads 216,000 eggs/hour (600 cases/hour) pallet accumulation chain conveyor can be customized in order Advanced vision system to reduce the time spent on loading full egg pallets and make Conveyor can be customized the system as self-sufficient as possible. The standard Stainless steel De-Palletizer system has been developed to minimize stops even if it is necessary to extract or insert interlayers or pallets. Washable Power Lift Egg Stack and Tray Lifting Device The Power Lifter is an ergonomic way of loading eggs to a high Handling, Robotic Automation, and Loading capacity processing or grading line. The Power Lifter is designed to handle stacks of 30 egg tray by using an ergonomic balancer that has the capacity for lifting up to 75 kg. It can easily handle Traditionally, eggs delivered to the processing plant are either supplied on pallets (off-line four stacks of six trays each in one movement. production) or delivered directly from the hen houses (in-line production).
