De-Handing Technologies for Banana Postharvest Operations—Updates and Challenges

Abstract

Many aspects of the agricultural industry such a field crop planting and harvesting and chemical application in fruit crops have been employing mechanization and automation solutions for decades. However, the de-handing operation in banana postharvest operations is usually performed manually. Mechanical or automated de-handing is a potential long-term solution to address labor shortages and the associated high costs. Bananas are mainly grown in developing countries located in tropical and subtropical regions, where the development of agricultural mechanization and automation solutions started only recently and is progressing relatively slowly. In addition, large-scale banana orchards are mainly distributed in hilly and mountainous areas, though there are also some small-scale banana plantations in plain areas. The complex environment of banana orchards and the aging farming population are other important factors that make it difficult to realize mechanized operation of banana de-handing. In recent years, researchers have proposed advanced techniques that may facilitate the development of mechanical de-handing systems. However, the successful adoption of mechanical de-handing technology still faces many challenges. This paper systematically reviews the existing research on de-handing technologies and component mechanisms. A comprehensive evaluation is carried out from the perspectives of feasibility of the mechanism design, stability of the model simulation and reliability of the prototype systems developed. The future challenges and opportunities for designing and practically adopting mechanical de-handing equipment are also summarized and discussed.

Inteligencia artificial en agricultura - Uso de algoritmos, drones y biosensores

“…Muchos aspectos de la industria agrícola, como la siembra y cosecha de cultivos de campo y la aplicación de productos químicos en cultivos de frutales, han estado empleando soluciones de mecanización y automatización durante décadas. Sin embargo, en las operaciones poscosecha de banano generalmente se realiza manualmente (Guo et al, 2022).…”

Automatic Detection of Banana Maturity—Application of Image Recognition in Agricultural Production

“…Bananas are rich in minerals and vitamins and have a high carbohydrate and low fat content [4,5]. As shown in Figure 1, the general process of bananas production from harvest to sale in the market is picking, cleaning, packing, transportation, storage, and, finally, mature bananas placed on the shelf for sale [6]. At different ripening stages after banana harvest, fruits contain different physiochemical and nutritional characteristics [7].…”

Effect on physiological properties of banana fruit based on pendulum impact test and storage

“…Banana fruit are the largest crop in terms of trade volume and planting area worldwide. Bananas are highly grown in tropical and sub-tropical countries including, China, India, Brazil, the Philippines, and Ecuador, and provide one of the most important sources of income for farmers ( Guo et al, 2022 ) . Banana is one of the most consumed and preferred fresh fruit by many people.…”
