摘要
针对于现有核桃破壳机两点受力破壳原理易造成破壳率低,高路仁率低的现象,研制"四点挤压式"核桃破壳机,并进行了"四点受力破壳"和"两点受力破壳"的对比试验,以及四点挤压式破壳机的初步试验。试验结果表明:"四点挤压式"核桃破壳机的破壳效果明显优于两点受力破壳,且可适用于不同尺寸大小的核桃。破壳效果和挤行程有很大关系,但和核桃本身大小尺寸关系并不明显。核桃的含水率为10%的条件下,当挤压行程为6 mm时,核桃的破壳效果最好,破壳率为100%,高路仁率为96.8%。
According to the problems of low shell breaking rate and whole kernel rate caused by exerting two forces, a four forces shell creaking machine was designed and made. The contrast shell breaking experiment of ＇two forces and four forces＇ and preliminary test were conducted, which showed the four forces shell breaking machine that apply to all over the size of walnuts had a better result than the two forces machine. The extrusion length has a significant impact on the shell cracking situation, but less on the walnut size. With the moisture content 10%, extrusion length 6 mm , cracking effect was the best, and the shell creaking rate and whole kernels rate were 100% and 96,8%, respectively.
