Plate type peeling machine for macadamia nut

Abstract

The invention relates to a plate-type huller for Australian nuts, comprising a motor or a diesel engine, a transmission mechanism, a feed hopper, a screw axis, a hulling plate, a peel-shell leading-out plate, a discharge hopper, a machine frame, etc. The huller is characterized in that: the screw axis is driven to rotate by the motor or the diesel engine through the transmission mechanism; the hulling plate is fixed on the machine frame; after entering from the feed hopper, nuts are squeezed and twisted by the screw axis and the hulling plate so as to crack nut peel and separate seeds out; the screw axis is equidistantly wound and welded on a hollow shaft; the hulling plate adopts a gradual change distance type structure; the distance between a working surface of the hulling plate and the screw axis partially becomes shorter from a working front end to a tail end and partially becomes longer; a maximum distance and a minimum distance are respectively a maximum nut diameter and a minimum nut diameter, and the distance between a working surface of the tail end of the hulling plate and the screw axis is a maximum seed diameter. The huller is simple in structure and low in manufacturing cost, can work fixedly or movably and process 800-1,600 kg of nuts per hour, does not need to have fruits graded, and is good in the quality of processed seeds.

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
