Semi automatic weighing and packing line VS Full manual weighing and packing
One food factory manufacture candy, biscuits, seeds etc, one year’s output required is 1800tons(250g/bag, one day’s output is 6 tons), whether need to purchase one set of semi-automatic weighing and packing line to replace present’s full manual weighing and packing, let us analysis:
Project 1: Semi-automatic weighing and packing line
1.Budget: Multihead weigher+Platform+band sealer=$10000-12000
2.Output: 50bags/minutes X 60minutes X 8hours x 300days/yearX250g=1800tons/year
4.The number of workers: 5 workers/day
Project 2: Full manual weighing and packing
(table weigher for manual weighing, band sealer for manual sealing the bag.)
1.Budget: table weigher+band sealer=$3000-$5000
2.Output and number of worker: Manual feeding, weighing, filling, sealing need 4-5 worker, speed is about 10 bags per minute, one day’t output required is 6 tons, need about 20-25 workers.
1.Budget: Project 2 is cheaper compared with Project1($7000’s difference.)
2.Accuracy:Project 1 save product 7-10 tons per year compared with project 2
3.Worker: Project 1 save 15-20 workers per year, if one workers’ salary is $6000 per year, for project 1, which can save$90000-$120000 per year.
Conclusion: Semi automatic packing line is better than full manual weighing and packing line
