Problems solved by technology

Because the surface of the walnut kernel is uneven, there are many folds, and the seed coat is deeply sunken in these folds, which brings certain difficulties to peeling. At present, the walnut kernel peeling method is relatively backward, and the walnut kernel cannot be peeled well. After soaking or steaming the walnut kernels in heated water, drain the water and peel them manually. This method is very

Example Embodiment

[0018] The process flow of the method for continuous peeling of walnut kernels of the present invention requires equipment used in a continuous lye soaking machine, a high-pressure spray machine, a double-effect washing machine, a peel and kernel separator, and a countercurrent dryer. Among them, the double-effect washing machine, the peel The kernel separator and countercurrent dryer adopt the double-effect washing machine, skin kernel separator and countercurrent dryer in the prior art.

[0019] Such as figure 1 , 2 As shown, the connected lye soaking machine includes a box body, the box body is connected by three working boxes, the three working boxes are respectively the feed sealing box 14 and the soaking holding box arranged from left to right. 15 and the inclined shower box 16, the feed sealing box 14 is connected with the inclined shower box 16 through the soaking and holding box 15, and the movable cover plate 12 is provided on the feeding sealing box 14, the soaking and ...

Abstract

The present invention discloses a continuous peeling method for walnut kernels, the method includes the following steps: the sorted complete walnut kernels are successively soaked in a continuous alkali solution soaking machine, then the soaked walnut kernels are put into a high-pressure spraying machine, the skins of the walnut kernels on the mesh belts of the high-pressure spraying machine are subjected to continuous and all-around impacts from high-pressure water produced by a high pressure pump, then the treated walnut kernels are put into a double-effect washing machine to be soaked and rinsed, and the skins of the walnut kernels are subjected to continuous and all-around impacts by the high-pressure water, then fiber and other light impurities on the skin of the walnut kernels are further removed by constant stirring and tumbling impacts produced by a wind pump, the skins are separated from the walnut kernels under the action of a separation device and circulating water in the skin and kernel separating machine, and then the walnut kernels are put into a countercurrent dryer to evaporate water on the surface of the walnut kernels. The continuous peeling method can realize the complete separation of the kernels and the skins of walnut kernels, the process is relatively simple and easy to operate, the production cost is low, the quality of walnut kernels can be significantly improved, the waste water is greatly decreased and the production cost is substantially reduced.

Description

technical field [0001] The invention relates to a peeling process, in particular to a continuous peeling method for walnut kernels. Background technique [0002] As one of the world-renowned "four major dried fruits", walnuts are not only delicious, but also nutritious, rich in protein, fat, minerals and vitamins. The skin of walnut kernels contains a highly polymerized compound called tannin in polyphenols. The bitterness and astringency produced by walnut kernels when eaten and the brown color in processed products all come from this substance. With the improvement of people's living standards, walnuts Deeply processed products have gradually entered the eyes of consumers. Walnut oil and cake, which are directly processed products of walnut kernel, affect their color and taste because of the walnut kernel skin. In order to obtain high-quality products, removing the skin of walnut kernels can significantly improve the edible taste and product quality of walnut kernels. Be...
