Abstract

This study aimed in onion production by evaluating cost and labor efficiencies of onion storage methods using either a ton-bag or a wire-steel pallet. New methods using ton-bag and wire-steel pallets were developed and applied to postharvest tasks, such as harvest packaging, transportation, and storage. The storage parameters evaluated for their effect on the logistics of onion production were: working duration, working hours, and cost expenditure. The longitudinal tensile strength of the ton-bag developed in this study was 16% higher than that of the conventional ton-bag. The wire-steel pallet developed in this study had 10% more storage capacity in a low-temperature storage room, and its truck loading capacity was more than doubled compared to that of the conventional steel pallet. There was no difference in the wasting rate during bulk storage between the newly developed wire-steel pallet and the conventional steel pallet, for 500 kg of onions. However, the bulk storage of 1,000 kg of onions using the wire-steel pallet was not found to be suitable, because the wasting rate of onions stored using the wire-pallet was 3.7% higher than that of onions stored using a conventional steel pallet. The time and the total investing costs for the bulk method decreased by 50.1% and 46.1%, respectively, compared to those for conventional harvest. In the bulk storage using the wire-steel pallet, the total storage cost decreased by 28.8%. Thus, it is estimated that we could have saved 18.3 billion won if the wire-steel pallet method about 30% of the total onion production (1,298,749 M/T) in 2016.

양파의 관행 수확과 저장 방식을 개선하여 벌크 상태로 수확하여 수송, 하역, 보관 및 저장할 수 있도록 톤백 및 와이어철제파렛트를 개발한 후 관행저장 방식과 벌크저장 후 저장성을 비교하고 그에 따른 노동투입시간 및 소요비용을 비교하여 양파의 산지물류비 절감 효과를 비교 분석하고자 하였다. 본 연구를 통해 개발된 톤백이 관행 톤백보다 길이방향 인장강도가 16% 높았으며, 개발한 와이어철제파렛트가 관행철제파렛트보다 약 10% 더 저장가능하고 차량 적재 효율도 2배 이상 향상되었다. 개발된 500 kg용 와이어 철제파렛트의 벌크저장과 관행 그물망 저장의 감모율에는 차이가 없었으나, 1,000 kg 이상 많은 양을 저장할 경우 와이어철제파렛트 벌크저장은 관행저장보다 감모율이 3.7% 높아 적합하지 않는 것으로 나타났다. 톤백을 이용한 벌크 수확이 관행 망 수확보다 노동시간이 50.1% 그리고 총 투입비용은 46.1% 감소할 수 있는 것으로 나타났다. 와이어철제파렛트를 적용한 벌크저장이 관행저장보다 총 저장비용이 28.8% 감소하였으며, 2016년 양파생산량(1,298,749톤)의 30%를 와이어철제파렛트 벌크저장으로 대체할 경우 연간 183억 원을 절감할 것으로 추정된다. 따라서 현재 산지업체들의 와이어철제파렛트를 조기 도입하여 정착시키면 전국적으로 노동력 및 비용 절감에 상당한 효과가 있을 것으로 판단된다.
