Research progress of commercial chestnut incision machine

The incision is the first step in the process of stir-fried Chinese chestnut with super sugar,which plays an important role in the deep processing industry of Chinese chestnut.At present,chestnut cutting by manual operation with high labor cost,low efficiency;or by batch disordered mechanical shell breaking with high kernel damage rate,irregular incision shape,can not meet the requirements of the commercial chestnut incision.Based on the analysis of the incision technical requirements of stir-fried chestnuts with super sugar,the structure and working principle of different types of chestnuts cutting machines were expounded,and the advantages and disadvantages of various types of chestnuts cutting machines were summarized.This paper summarizes the research status of chestnut cutting machinery abroad,analyzes the problems existing in chestnut incision machinery,such as low productivity,high damage rate of chestnuts,inaccurate position of cutting,low quality of opening,poor adaptability of equipment,low reliability,and imperfect cutting technical standards.The development strategies of optimizing the incision process,improving the efficiency and quality of the incision,introducing machine vision technology,improving the intelligent level of the incision,perfecting the standardized production system and improving the versatility of the equipment are put forward.
