A low-quality walnut means a walnut with a thick shell and ingrown partitions. Also, a low-quality walnut includes an overdried walnut, which has increased brittleness and breaks even with the most careful manual cracking. Separately, you can select a freshly picked still wet walnut, it retains its integrity as much as possible and gives a high percentage of the whole kernel, however, manual labor is required to sort it.
What should processors who have purchased low-quality, over-dried or wet walnuts do?
Usually such a walnut, after cracking and sorting on a vibrating screen with aspiration, is sent to manual sorting. One person per shift sorts out about 17 kg of cracked walnuts. It turns out that the more low-quality walnuts, the more workers are needed, and this is an additional cost of time and finances.
At enterprises, this issue is solved with the help of a walnut breaker after the cracking machine. Depending on the purpose of production, it is installed immediately after the nutcracker or after the sorting equipment.
If the purpose of production is to obtain a whole kernel, the walnut breaker is installed after the sorting equipment – vibrating screens and aspiration. With a good walnut, sorting equipment will do up to 70% of all sorting work. The rest of the part that fell into the gap will go to the walnut breaker and re-sorting.
In industries that are not aimed at obtaining a whole kernel, the walnut breaker is installed immediately after the nutcracker.
Thus, enterprises avoid manual labor as much as possible and reduce the cost of the product. Besides:
– you can buy a walnut from various private farms and processing it is guaranteed to make a profit;
– without manual labor, processing volumes immediately increase;
– no worries about hiring staff and monitoring their work.
Such productions earn on the sale of large volumes of fractions – 1/4, 1/8, crumbs, and parts of a whole kernel.
