ADVANTAGES AND DISADVANTAGES

Advantages of line system over booth system

• Since carcasses are conveyed to each dressing station there is no need for operation to be idle while carcasses are being hoisted. Thus time is saved. Compared to traditional system of slaughter the line system is said to be safer for operation.
• Because the carcasses do not touch the floor the dressing is more conveniently carried on the rail and it is hygienic.
• Elimination of handling of heavy shackles trolleys, spreaders, unnatural stooping by the personnel and use of mechanical tools reduces the tedious labour operation being carried out by the operatives. A comfortable operative position either at floor level or on stationary or elevating platform is provided.
• The reduction of loss of motion and unnecessary movement of the carcass enhances the saving of space.
• The use of efficient line system makes for increased output and enhances the value of the carcass, hide and offal because of the superior workmanship.

Disadvantages

• Since, line system is mechanically complex high standard of engineering maintenance is needed and when breakdowns do occur production ceases completely. The repetitive nature of the work can be largely offset by job rotation if personnel are so trained.
• Meat inspection is sometimes made more difficult and possibly less efficient.
• Proper carcass and offal conveyor synchronization, a good identification system, adequate, efficient and conscientious inspection staff, proper inspection points with ability to coordinate findings, an efficient recording setup and adequate time for the examination of each carcass are to be essential to have an efficient meat inspection.
• Since higher rates of slaughter are involved, separate recording staff particularly for detailed information should be utilised.
• A system of audio links should be used for communication between inspectors and recorders, one of whom is required for each line.
