Field Weighment and Transport Docket Verification for Raw Flax
Raw flax field dockets match scutching intake when weighbridge tares, moisture regain corrections, and lot dockets reconcile under standard ISO dry mass limits.
Mud Accretion
Soil Accumulation
Agricultural raw materials harvested from fields often carry soil and debris that attach to the plant during collection. In wet harvesting seasons, mud accretion on flax straw can significantly increase the gross weight of the delivered crop. This additional mass must be identified and subtracted to determine the true fibre weight.
Spinning mills run the risk of overpaying for agricultural deliveries if they do not account for this non-fibre material.
Processing Hazard
Excessive dirt carried by flax straw damages the mechanical parts of processing machinery. When flax with heavy mud accretion enters the scutching line, the dried soil turns into abrasive dust that wears down the metal rollers and clogs the carding clothing. This wear increases the frequency of machine maintenance and reduces the lifespan of the equipment.
It also contaminates the processing environment, requiring more frequent shutdowns for cleaning. To mitigate this risk, processing mills may pre-clean the straw or reject shipments that exceed acceptable dirt levels. This protective measure is essential for maintaining the productivity of the spinning mill during periods of wet harvest weather.
Weight Adjustment
Accurate determination of the clean weight of flax requires subtracting the estimated weight of soil and moisture. Technicians inspect the incoming bales for mud accretion and apply a dockage percentage to the gross weight. This percentage is based on laboratory tests of sample bundles that are washed and dried.
The resulting adjusted weight forms the basis of the payment to the grower, ensuring the mill pays only for useable plant material.
