Background technique

Most areas of our country are rich in wild nut resources. The development of green resources of wild nuts and their deep processing can help farmers in mountainous areas get rich locally. Some shelled fruits are not suitable for long-term storage due to their short shelf life; some nuts have a wide planting area and their output is increasing year by year. There are problems of difficult transportation and oversupply. Therefore, deep processing of nuts is necessary to develop new products. Shelling is a process that must be carried out before further processing of shelled materials. Nut shelling is very important but very difficult in agricultural product processing. Traditional shelling adopts manual methods of knocking, smashing, and stepping, which is labor-intensive and low in shelling efficiency. Old-fashioned shelling machines generally use direct impact and rolling to achieve shelling, and this shelling method is likely to lead to a high rate of nut damage and even blockage, which not only affects production, but also affects processing quality. Moreover, the existing nut shelling machines are usually only aimed at the shelling of certain nuts, and generally have poor versatility and a high rate of broken kernels.
