Lab Indent Cylinder/ Grader
Precision laboratory grading equipment designed to separate rice based on length, enabling accurate determination of broken and whole grain percentage for quality analysis.
What is Lab Indent Cylinder/ Grader?
The Laboratory Indent Cylinder (also known as a length grader) is an indispensable analytical machine utilized in seed testing laboratories and grain processing facilities to categorize agricultural material strictly by its length.
It separates shorter grains - such as broken rice kernels or undersized weed seeds from longer whole grains.
This testing equipment is critical for B2B agricultural operations; it allows technicians to establish highly accurate head rice yields (HRY), certify seed lot purity, and fine-tune large-scale commercial graders, thereby ensuring strict compliance with international quality and export pricing standards.
Common Applications
Commercial Rice Milling Facilities
Essential for precisely calculating the ratio of broken rice to head rice to establish the market value and grade of a milled batch.
Seed Testing & Certification Labs
Used for rigorous seed lot purity analysis by efficiently removing undersized weed seeds, half-seeds, and foreign physical impurities.
Grain Research & Breeding Institutes
Utilized by agronomists to evaluate the dimensional consistency, hardiness, and length profile of newly harvested or experimental grain varieties.
Malt & Brewing Quality Assurance
Ensuring highly uniform barley grain lengths to guarantee consistent germination rates and standardized malt production profiles.

Variable Speed Control
Ranging from 20-60 rpm, this allows technicians to dial in the exact centrifugal force required for optimal separation based on the specific weight, friction, and moisture content of the sample.
Quick-Change Indent Cylinders
Designed with a modular, quick-release mechanism that allows operators to swap cylinders with varying indent sizes in under two minutes. This versatility accommodates rapid transitions between testing entirely different grain types.
Multi-Angle Trough Adjustment
Features a finely calibrated, externally adjustable central collection trough. By smoothly altering the precise angle of the trough during live operation, technicians can perfectly control the separation cut-off point, ensuring zero whole grains are lost to the broken fraction.
