Double-channel shell breaking device and shell breaking method for macadimia nuts

Abstract

The invention discloses a double-channel shell breaking device for macadimia nuts. The device comprises a shell breaking mechanism and a drive mechanism, wherein the shell breaking mechanism comprises a shell breaking box, a material guide box cover, a cutter head, a shell breaking knife and a cutter head shaft; the material guide box cover and the shell breaking box are mounted in a matched manner to form a shell breaking box chamber; the cutter head shaft penetrates through the shell breaking box chamber and is driven by a drive mechanism; the cutter head comprises a cutter head body and a first shell breaking knife; the cutter head is arranged in the shell breaking box chamber, sleeves the cutter head shaft and divides the shell breaking box chamber into two breaking chambers; second shell breaking knives are mounted on inner walls of two sides of the shell breaking box chamber; a material inlet and a material outlet are formed in the material guide box cover. According to a shell breaking method, shells of the nuts entering the breaking chambers are broken under the shearing action produced when the first shell breaking knife is staggered with the second shell breaking knife in the rotation process, and then nut kernels and the shells are sent out. The whole shell breaking process is continuous, the efficiency is high, and the shell breaking effect is good.

Description

technical field [0001] The invention relates to the technical field of nut cracking equipment, in particular to a dual-channel macadamia nut cracking device and a cracking method. Background technique [0002] Macadamia nuts have high nutritional value and are known as the "King of Dried Fruits". They are widely loved by people, but the shell of macadamia nuts is hard and difficult to break. There are two ways to break the shell and mechanically break the shell. [0003] The method of manual shell breaking is mainly to use shell breaking pliers (such as a kind of macadamia nut shell breaking pliers disclosed in the Chinese utility model patent with the application number of 201420370566.9) to clamp or compress the nut shells one by one to make them broken. This shell breaking method is extremely efficient. Low, labor-intensive, only suitable for household use, can not meet the needs of processing enterprises. [0004] Compared with manual shell breaking, mechanical shell b...

AI Technical Summary

Problems solved by technology

The extruding and sawing macadamia nut shelling machine can better ensure the integrity of the nuts, but the equipment still needs nuts with good shape consistency to achieve the ideal shelling effect, otherwise there will be some sawing failures. The problem of opening or squeezing is not broken, and the finished product yield rate of one-time processing is poor
