Superior Indent Length Graders
Model C11
 


 

The cylinder grain cleaners perform their separation by finding minute differences in length. 
With an understanding of the cylinder action and the function of the pickup through inside the cylinder, one can clean grain or seed with accuracy surpassing other types of equipment.

The Indent Separator is a simple, single cylinder machine with a main drive, conveyor shaft, and cylinder.
A 23" diameter cylinder is the main part of these length graders.

The size of the indent pockets on the inside surface of the cylinder determines the length of the lifted material. Any material the same size as, or smaller than, the indent pockets is lifted and dropped into the receiving trough. The transportation of the material from the trough to an outside spout is performed by a screw conveyor. The remaining larger material is taken to the discharge spout by blades connected to the outside bottom of the trough.

Features:

  • Cylinders are available in many sizes for a wide variety of seeds.

  • Can be put together in a series flow (to re-clean seed) or parallel flow (for maximum capacity).

 

Basic instructions from the original literature:
  1. Adjust for the correct speed of the cylinder - Look through the inspection opening on the discharge end of the machine and see that the trough end is setting about level.  Then regulate the speed of the cylinder so most of the grain or seed picked up by the indents will fall straight into the trough from the top part of the cylinder.

    *If the grain or seed is carried past the left side of the trough, the speed is too fast.  If most of the grain or seed falls into the trough on the right side, the speed is too slow.

    *To increase the speed of the cylinder, lower the motor base by the adjustable turnbuckle, thus increasing the pitch diameter of the motor sheave.  To decrease speed of the cylinder, raise the motor base by the adjustable turnbuckle, thus decreasing pitch diameter of the motor sheave.
     
  2. Adjust trough for desired separation - Adjust or tilt the trough one way or the other until you receive the correct length of grain or seed that is desired.  It is very important, after having made a trough adjustment, to allow the machine to run a minute or two before checking discharges to determine if a further trough adjustment is necessary.
     
  3. Adjust position of the retarder - To pick out the small grain and seed from the large, a grain or seed bank must be kept in the cylinder at all times.  The retarder at the discharge end of the cylinder creates this bank.

    *By keeping the retarder at a point furthest from the cleanout position, a high bank will be created and by moving the retarder to a point at or near the cleanout position, a low bank will be obtained.  If the bank is kept too high, some of the larger grain or seed may go over the edge of the trough with the small.  If kept too low, the smaller grain or seed will go out with the large.
