核桃破壳取仁生产线的设计与试验

Design and experiment on walnut broken and shell kernel separation production line

为解决人工破壳取仁的繁重劳动,通过对核桃破壳工艺路线及壳仁空气动力学特性差异关键技术的研究,研制适合我国新品种核桃的破壳取仁加工生产线。生产线主要由3FJ―001型原核桃分级机、变间距挤压式核桃破壳机、滚筒式桃仁分级机、离心式二次破壳机及风选式壳仁分离机组成。整个生产线实现一次破壳率可达到80%以上,半仁率平均含量76%,1/4仁平均含量14%;经过二次破壳,破壳率比一次破壳平均提高18%,壳仁分离生产率可达到400kg/h以上,同时碎末和硬壳得到充分利用。

For solving heavy labor from artificial shell and kernel taking,through the research on the key technology of shell breaking process and shell kernel aerodynamic characteristic differences on nuts,it was developed suitable for new varieties broken walnut shells to take Jen processing line.The production line mainly adopts 3FJ—001type raw walnut classifier,variable spacing extrusion type walnut shell breaking machine,drum peach kernel classifier,centrifugal secondary breaking machine and winnowing type shell and kernel separator.The entire production line to achieve a shell breaking rate can reach more than 80%.The half kernel rate average content 76%.The quarter kernel rate average content 14%.After second shell breaking,shell breaking rate than first broken shell increased an average of 18%.Shell kernel separation productivity can reach more than 400kg/h,at the same time;crumb and shell can be fully utilized.
