Problems solved by technology

Due to the uneven size and different shapes of cashew nuts, and the small gap between the shell and the kernel, and the shell liquid has a corrosive effect on human skin, this brings great difficulty to the shell breaking process. The shell quality is poor and the whole kernel rate is low, which seriously limits the development of cashew nut processing industry

Embodiment 1

[0018] (1) Impurity removal: The shelled cashews first use a vibrating screen and a winnowing machine to remove foreign matter such as empty shells, branches, leaves, and pear fibers; then use water immersion and stirring to remove impurities such as stones and sediment;

[0019] (2) Classification: The shelled cashews after cleaning are classified according to the particle size, using rollers or screens with apertures of 24 mm and 20 mm respectively, and the shelled cashews are divided into three grades: large, medium and small. Put the graded shelled cashew nuts into corresponding utensils or packaging bags and mark them;

[0020] (3) Steam heating: Put the graded shelled cashew nuts in a high-pressure cooking pot with clean water for steam heating, the heating temperature is 105°C, and the heating time is 40 minutes;

[0021] (4) Rapid cooling: quickly take out the heated shelled cashew nuts, and immediately put them in a refrigerator at a temperature of 4°C for 1 day;

Abstract

The invention relates to a cashew shell breaking method and belongs to the technical field of nut shell breaking processing. The method includes the steps of first removing impurities of harvested cashews with shells through vibration, winnowing, soaking in water and mixing, performing grading, steam heating, rapid cooling and the like processing, breaking shells of the cashews with the shells through a homemade cashew shell breaking machine, and finally separating cashew kernels from the cashew shells through a winnowing machine and a vibrating screen. By means of the cashew shell breaking method, the whole kernel rate is high, and the process is easy to operate, high in practicability, low in energy consumption, good in stability and suitable for bulk industrial production.

Description

technical field [0001] The invention relates to a shell breaking method, in particular to a shell breaking method of cashew nuts, and belongs to the technical field of shell breaking processing of cashew nuts. Background technique [0002] Cashew nuts are also known as Jurushu, chicken cashew nuts, and Jieshou fruit. Evergreen tree, trunk upright, up to 10 meters. Cashew nut is a kind of kidney-shaped nut, belonging to the genus Cashew in the Anacardiaceae family. It has rich nutritional value and can be used for cooking and medicinal purposes. Its edible part is the kidney-shaped part that grows on the top of the false fruit, about 25 mm long, from blue-gray to yellowish-brown, with a hard shell and a seed kernel inside, which contains high calories, and its heat source is mainly fat , followed by carbohydrates and protein. It is native to America. [0003] Cashew nuts are one of the world's famous four major nuts (walnuts, almonds and hazelnuts). Its taste is mellow, ...
