Chain type peeling machine for macadamia nut

Abstract

The invention relates to a chain-type huller for Australian nuts, comprising a feed hopper, a driving device, a hulling mechanism, a machine frame and a nut shell collecting bucket. The huller is characterized in that: the driving device adopts a motor or a diesel engine as a power source; a power output shaft is connected with a gear or a belt pulley and then transmits power to the hulling mechanism; the hulling mechanism is a mechanism consisting of a screw axis, an elastic chain-type hulling piece and a hulling cavity; a feed hopper is arranged above the hulling cavity; the other end of the hulling cavity is a fruit outlet; the nut shell collecting bucket is arranged below the hulling cavity; the huller for Australian nuts can hull big nuts first and then hull small nuts without grading fruit, has high hulling thoroughness, can separate peel and shells, and can be matched with and arranged on a production line. The huller is simple in structure and low in manufacturing cost, can work fixedly or movably, and can process 800 kg of nuts per hour.

Description

technical field [0001] The invention relates to a shell shelling machine, in particular to a machine for shelling macadamia nut fiber shells (pods). Background technique [0002] Macadamia is a tropical nut variety introduced from Australia. It is suitable for planting in the south of Guangxi Guizhong, Yunnan, Guangdong, Fujian, Sichuan and other places. It is a rare and valuable nut variety with high nutritional value, but macadamia has two layers. Shell, the outermost layer is a green pod, and the inner layer is a brown hard shell. Although there are many nut shelling machines reported in open literature, they are all for general nuts, such as pine nuts, hazelnuts, walnuts, and chestnuts. The special equipment designed for the characteristics of the machine cannot be used for removing macadamia nuts. For nuts collected from the field, it is best to remove the pods within 2 days to prevent fruit germination and rot. If the pods are piled up, the temperature will rise due ...

AI Technical Summary

Problems solved by technology

If stacked with pods, the temperature will rise due to respiration, and the nuts will ferment and spoil

At present, the shelling machine used to process macadamia nuts is still blank in China. There are chain shelling machines dedicated to shelling macadamia nuts abroad, but they are expensive and not suitable for the purchasing power of domestic growers. "Tropical Crops Mechanization" Huang Jiahan, Zhu Deming reported that macadamia nuts in some places currently use processing machinery, of which the pods use a twin-screw pod removal machine, and the hard shells use a pressure plate type shell breaking machine, but no specific structure of the twin-screw pod removal machine has been disclosed
