Multi-blade food processing apparatus
View Patent ↗A multi-blade food processing apparatus having two independent blade assemblies, each of which blade assemblies having two opposed horizontal cutting blades, wherein the upper of two independent blade assemblies is selectively removable from the apparatus, the cutting blades are spaced apart in elevation, and are offset in orientation 90 degrees for improved cutting efficiency. The blade assemblies are positioned at 90 degrees from each other but may include additional positions for orienting the blades at any angle with respect to each other.
1. A blade assembly comprising,
a lower blade assembly formed with a main hub having two opposed cutting blades fixed to the main hub and at least one slot on the outer surface of the main hub;
an upper blade assembly formed with a hollow cylindrical hub having two opposed cutting blades fixed to the outer surface thereof having at least one key on the interior surface thereof mountable on the outer surface of the main hub, and
the cylindrical hub of the upper blade assembly fits onto and is secured to the main hub by the at least one key cooperating with the slot on the main hub, the cylindrical hub being selectively removable from the main hub;
wherein the lower of the said two independent blade assemblies is operatable alone as the only cutting means or with the lower blade assembly and upper blade assembly functioning together as the cuffing means.
2. The blade assembly of claim 1 , wherein each blade in each assembly is spaced apart between about 12 to 30 mm from each other.
3. The blade assembly of claim 1 , wherein the at least one slot is inclined towards the rear of the blade cutting surfaces.
4. The blade assembly of claim 1 , wherein the at least one slot on the main hub includes a substantially vertical opening for receiving the at least one key on the upper blade assembly and a horizontal region towards the rear of the cuffing surfaces at the bottom of the vertical opening to prevent the upper assembly from lifting out of the vertical opening.
5. The blade assembly of claim 1 , wherein the cutting blades are curved cutting blades.
6. The blade assembly of claim 1 , wherein the two opposed cuffing blades on the lower blade assembly and the upper blade assembly extend substantially horizontal from the hubs.
7. The blade assembly of claim 6 , wherein the two opposed cutting blades on the lower blade assembly and the upper blade assembly are spaced apart.
8. The blade assembly of claim 1 , wherein the two opposed cuffing blades on the lower blade assembly and the upper blade assembly are spaced apart.
