Experimental Study Of Citrus Reticulata Peel Method

Citrus is the world’s largest fruit. In recent years, global citrus production is100million tons, the planting area of6.7million hectares. Citrus fruit has high nutritional, medicinal and health care value. Considered as a kind of health food, it attracts much attention from home and abroad. This article aims to citrus automatic, fast peeling provide a new way to solve the problem of citrus processing, but also conducive to the design and manufacture of automatic processing lines, which improve labor productivity, reduce processing costs and improve the competitiveness of China’s citrus in the international market, sustainable development has a very important practical significance to promote the citrus processing industry.This article leniency Citrus reticulata material parameters departure. This article leniency Citrus reticulata material parameters departure to find Citrus reticulata peeled and technical methods. The main measurement of Citrus reticulata weight, fruit diameter, height, thickness of the peel material parameters provide a theoretical basis and data base for Citrus reticulata peeled technology and equipment.In this paper, citrus whole fruit compression test. And citrus compression resistance and fracture displacement amount for statistical analysis, citrus compression resistance is greater than70N rupture displacement volume greater than12mm. Citrus mechanical automation peeled, kayaking tool citrus maximum pressure should not exceed70N, citrus amount of compressive deformation should not exceed12mm. Citrus peel shear test, the average shear stress of the inner surface of the peel is1800Pa, the average shear stress of the outer surface of the peel is2500Pa. Citrus peel on the horizontal and vertical shear force difference was not significant.This study tested the pretreatment and peeling methods on citrus, citrus grading, cleaning, blanching, go to the top, ring cutting leather, leather etc.. Citrus size mainly distributed in between55mm to75mm, according to the national standard of the largest fruit size is5mm for a class, can be divided into6levels. By blanching treatment on citrus, water temperature should be controlled at80℃to90℃, heating time should be controlled at around40s, citrus fruit flavor changes little, fruit peel of Citrus rate increased significantly. Circumcision of scratch opening of Citrus reticulate, citrus fruit diameter along the maximum ring cut a week of scratch method of peeling rate higher than the traditional method of peeling of scratch. On citrus to top test, remove the Guobing pedicle of citrus peel rate higher than did not go to the top of the citrus peel. Citrus peel test, will scratch opening up the skin, improve the orange peel rate.Through the Theory, peeled testing, prototyping, puts forward the overall scheme of Citrus reticulate peel equipment. And the simulation design of key parts, including special conveying chain plate, special feeding push plate, toping device, ring cutting and peeling device. With citrus feeding into a row, citrus positioning, high degree of automation, can meet the requirements of the production of Citrus reticulate peel.
