The hazelnut opening machine developed and produced by our company has the advantages of energy saving, simple operation, and high output. It is widely used for opening American large round, two round, large pointed, two pointed, and domestically produced Northeast hazelnuts, and has been highly recognized by customers. The equipment is divided into one group (with a production capacity of about 300 kilograms per hour), two groups (with a production capacity of about 600 kilograms per hour), three groups (with a production capacity of about 900 kilograms per hour), four groups (with a production capacity of about 1200 kilograms per hour) and other specifications. Hazelnuts need to be soaked in hot water before entering the opening machine, and steam should be used to keep the shell moist and warm, thereby reducing damage during the opening process and maintaining material integrity. The soaking time of materials is determined by the temperature of the soaking water. The successful development of this device has replaced the era of manual hazelnut opening in the past.
