Detailed Description
For the purpose of facilitating an understanding of the present invention, the present invention will now be described by way of examples. It should be understood by those skilled in the art that the examples are only for the understanding of the present invention and should not be construed as the specific limitations of the present invention.
Example 1
The embodiment provides a process for intelligently screening walnut kernels by using a sorting machine, which comprises the following steps:
the walnut kernel is sequentially conveyed by the conveying assembly of the color sorter through the visual identification assembly and the biological identification assembly, data obtained by the visual identification assembly and the biological identification assembly are fed back to the control assembly to control the compressed air removing assembly to remove moldy walnut kernels, deteriorated walnut kernels, walnut kernel outer hard shells and diaphragma.
The experimental results using the novel color sorter in this example are as follows:
the walnut kernel comprises the following components: the weight of the first path of Xinjiang white kernels, the first path of northern white kernels, the first path of big kernels and the first path of miscellaneous kernels is as follows: 40kg, 25kg, 10kg, total 100 kg. Impurities in walnut kernels: mildewed walnut kernels (with light green surface color), broken kernels (with light yellow surface color), walnut kernel outer hard shells, diaphragma juglandis (interlayer between walnut kernels) and the like, wherein the total weight of impurities in each walnut kernel is less than 0.5 percent.
Slowly pouring the walnut kernels doped with impurities into an oscillating conveyor, oscillating and uniformly dividing the walnut kernels by the conveyor, and then sending the walnut kernels into a screening machine to finish picking. The above procedure was repeated 10 times, and the results are shown in table 1.
TABLE 1
As can be seen from the test results in Table 1, the rejection rate of the walnut kernel outer shell and the diaphragma reaches 100%, the rejection rate of the deteriorated walnut kernel reaches more than 98.65% on average, and the rejection rate of the mildewed walnut kernel is more than 99.16%. The application of the novel color selector to walnut kernel picking can greatly improve the quality of the walnut kernels after picking, thereby improving the quality of walnut milk products.
Comparative example 1
The experimental results using the conventional color sorter in this example are as follows:
the composition of the walnut kernel, the kinds and contents of impurities, and the test method in this comparative example were the same as those in example 1. The test results are shown in table 2.
TABLE 2
From the test results in tables 1 and 2, it can be seen that in example 1, the novel color sorter with visual identification and biological identification components is adopted, the rejection rate of the walnut kernel outer hard shell and the diaphragma reaches 100%, the rejection rate of the deteriorated walnut kernel averagely reaches more than 98.65%, the rejection rate of the mildewed walnut kernel is more than 99.16%, and the false kick rate is lower than 2%. In comparison example 1, the traditional color sorter is adopted, the rejection rate of the walnut kernel outer hard shell and the diaphragma is 80-85%, the rejection rate of the deteriorated walnut kernel is about 50%, the rejection rate of the mildewed walnut kernel is about 60%, the color sorter is far lower than the novel color sorter used in example 1, and the false kicking rate is up to more than 8% and is far higher than the novel color sorter used in example 1. Therefore, the novel color sorter with the visual identification and biological identification components is adopted, so that the mildewed walnut kernels and the deteriorated walnut kernels in the walnut kernels can be effectively removed, the removing rate is extremely high, the false removing rate is low, and the taste and the quality of the walnut drink can be effectively improved.
