@vgod00 It depends on what variety of walnut you are talking about. A good cracking variety such as Chandler has a thin shell and can be as low as 45% shell mass. However, we have tested some walnuts from central Asia that are as much as 60% shell. We usually estimate it to be 50% shell and 50% kernal by weight when sizing our equipment.
@DutarTash For just the equipment shown in this video it would be about $400,000 to $500,000 USD. That does not include the building and does not include electronic inspection. The electronic inspection alone could cost another $400,000. However, it would take the place of 20 people.
What percentage of the kernel is obtained in the output product? Or what percentage of the kernel is lost along with the shell? Is the final product graded according to the sizes of the kernel?
@qqqquito I all depends on how the operator uses the machine and what variety of walnut you are cracking. With cracking varieties (Chandler, Howard, Tulare) there will be more halves. It is much easier to separate the shell from the halves. We use aspirators to separate shell from the kernal.
@qqqquito The aspirators can be adjusted so almost no shell is left in the kernal but a lot of kernal will go with the shell. Or it can be adjusted so almost no kernal goes with the shell but there will be a lot of shell left with the kernal.
The sizes graded are usually: Halves, Large Pieces (larger than 1/2 inch), Small Pieces (smaller than 1/2 inch).
@qqqquito Even with all the separation this machine does the kernals still need to be inspected by human eyes to get all the shell out of the kernal. Even the high speed laser/camera sorters need to have human eyes do a final inspection. Our shelling line doeas a great job of cracking and separating MOSTof the shell from the kernal and producing a majority of halve kernals.
It depends a lot on the variety of walnut you are cracking. The non-cracking varieties (Hartley, Franquette) are about 35% where the cracking varieties (Chandler, Howard, Tulare) are about 85% halves. We have had some customers report 90% and better using our crackers.
The day this video was shot we were testing the line with left over nuts that were a mix of varieties and a mix of sizes. If you size the wlanuts before running them through the cracker you can improve the percentage of halves.
12- The material is then dropped onto the scalping deck. Walnut halves drop through this screen (see 2:56) and then go through two aspirators to separate as much shell from the walnut halves (see 3:29)
13- The halves are then conveyed to a bin for storage (see 3:29)
8- The cracked pieces, nut and shell, are sorted by size on the vibrating table. Pieces smaller than .75 in. (19mm) drop through and are conveyed to the piece sizing deck.. (see 1:50)
9- The piece sizing deck separates the pieces into small, medium, medium-large, and large pieces (see 2:20)
10- Each size is aspirated to remove most of the shell (see 2:28)
11- The cracked walnut pieces that do not drop through the first sizing deck are aspirated to remove most of the shell (see 2:43)

What percentage of the total mass of the walnut does the shell make? Thanks for the video.

A description of the process:
1- In-shell walnuts are loaded into bin dumper (see 0:08)
2- Bin dumper unloads walnuts (see 0:38)
3- Walnuts are fed into elevator (see 0:56)
4- In-shell walnuts fall into surge bins before being cracked (see 1:01)
5- In-shell nut are fed into the two walnut crackers (see 1:11)
6- The walnuts are cracked and drop onto the collection conveyor (see 1:27)
7- The cracked walnuts are elevated up to the first sizing deck (see 1:38)
