Cashew nutshell crusher

Abstract

The invention provides a cashew nutshell crusher, which comprises a tube body, a cutter blade and an electric motor, wherein a tube cover seals the top end of the tube body, the cutter blade comprises an upper cutter blade and a lower cutter blade, the electric motor is arranged at the outer side of the bottom of the tube body, and a rotating shaft of the electric motor extends into the tube body, wherein the upper cutter blade and the lower cutter blade are placed in an overlapped way, and are connected with a rotating shaft of the electric motor, the upper cutter blade comprises a middle part and two rotary cutters positioned at the opposite ends of the middle part, and included angles beta 1 and beta 2 formed between the projection of the butter back and the cutter edge of the rotary cutters and the horizontal line in the horizontal plane are respectively between 20 and 30 degrees and between 30 and 50 degrees. Through the crusher, cashew nutshell crushed products with satisfactory granularity can be obtained, so the further processing can be carried out.

Description

technical field [0001] The invention belongs to crushing machinery, in particular to a cashew nut shell crusher. Background technique [0002] Cashew nut is a perennial tropical evergreen and drought-tolerant tree fruit tree. The cashew nut kernel is rich in nutrition and is a high-grade food, but it only accounts for 25% of the weight of the cashew nut, and the rest of the weight is the cashew nut shell. However, the utilization of cashew shells has not received enough attention. For example, cashew nut shells have long been burned as fuel or even discarded as waste in cashew producing countries around the world. [0003] With the advancement of technology, studies have found that cashew nut shells contain 40% of cashew nut shell oil, and cashew nut shell oil contains 85% of quasi-acid and carduol. The catalyst reaction can introduce some active groups into the long chain of the resin, thereby changing the molecular arrangement structure of the resin, and then changing th...

AI Technical Summary

Problems solved by technology

Cashew nut shells, for example, cannot be crushed using a conventional universal grinder

When using it, it is found that the universal grinder cannot work within a short time (for example, less than 20 seconds) after adding the cashew nut shell

The reason is that, unlike the composition of most nut shells, the cashew nut shell contains a large amount of cashew shell oil, which will generate phenolic resin when heated during the friction process, which will hinder the further progress of crushing, so it is suitable for other nuts Shell crushing equipment is not suitable for cashew nut shells
