A kind of walnut selection processing technology

Abstract

The invention discloses a walnut selection and processing process. The process comprises the steps of (1) feeding dried walnuts to pass through a winnowing device to remove empty shells; (2) feeding the walnuts subjected to empty shell removing to get into a flotation device to separate out part of hollow walnuts, wherein the separated walnuts can be continuously and quickly air-dried; (3) feedingthe walnuts of which the hollow ones are partially removed to get into an ultraviolet color sorter to remove the moldy walnuts; (4) feeding the walnuts of which the moldy ones are removed into a grading separation device to be divided into four grades; and (5) packaging the graded walnuts as the selected walnuts, wherein the completely unshelled walnuts can also be subjected to food deep processing. Through the walnut selection and processing process, the quality and processing and production efficiency of the walnuts are substantially improved. As the sorted walnuts are graded obviously, theproduct additional value of the packaged walnuts is effectively increased. The poor-quality walnuts can also be usable, for example, can be manufactured into oil and processed into feed. The removedhollow shells can also be used as activated carbon and other materials, so that industrial economic benefits are further increased, and the bottleneck problem of rapid development of the walnut industry is solved.

Description

technical field [0001] The invention relates to the field of walnut processing, and mainly relates to a walnut selection processing technology. Background technique [0002] With the rapid development of the national walnut industry, the output of walnuts is also increasing, and the selling price of walnuts is also dropping rapidly. Only relying on the sale of walnuts can no longer solve the problem of the whereabouts of a large number of walnuts. At present, walnuts sold in the market have not been refined, so it is common for walnuts to have empty shells, some shells and some mold. Some walnuts that rely on manual sorting are not only inefficient, but also the quality of the walnut kernels cannot be guaranteed. ; Since the quality of walnuts has not been improved for a long time, and the output of walnuts has increased year by year, the price of walnuts has decreased year by year, and in some places there is even a situation of no benefit, which has greatly dampened the en...

Problems solved by technology

At present, walnuts sold in the market have not been refined, so it is common for walnuts to have empty shells, some shells and some mold. Some walnuts that rely on manual sorting are not only inefficient, but also the quality of the walnut kernels cannot be guaranteed. ; Since the quality of walnuts has not been improved for a long time, and the output of walnuts has increased year by year, the price of walnuts has decreased year by year, and in some places there is even a situation of no benefit, which has greatly dampened the enthusiasm of the walnut planting industry; in the deep processing of walnuts On the one hand, due to the failure of effective grading of processed raw materials, high-quality raw materials and inferior raw materials are mixed together, and targeted processing cannot be carried out according to raw materials of different qualities, and high-quality and high value-added products cannot be processed, resulting in a gap in the technology for deep processing of walnuts , making deep processing a bottleneck for the development of the industry
