In feed, grain, and food production, decisions are only as reliable as the sample and test data behind them. TEKPRO helps operators improve confidence in intake checks, pellet quality control, and stored grain inspection with equipment designed for accurate sampling, repeatable testing, and dependable day-to-day use. From bulk grain intake to pellet durability measurement and insect detection, our systems support quality, safety, and operational consistency across the post-harvest chain.

Why representative sampling matters

A laboratory result is only useful if the sample truly reflects the material being tested. In grain intake, feed production, and storage operations, poor sampling can lead to inconsistent quality decisions, missed contamination risks, and unnecessary production losses.

Representative sampling supports:

• More dependable quality assessment at intake
• Better confidence in moisture, contamination, and suitability checks
• Stronger process control across grain and feed handling
• Reduced risk from inconsistent manual sampling methods

TEKPRO’s Samplex range is designed to help operators collect representative core samples from bulk deliveries and process streams, supporting more reliable quality control in demanding industrial environments.

Bulk grain sampling for intake and handling

Bulk loads can vary significantly across a single truck, trailer, rail car, or silo. That makes consistent sampling essential for feed mills, grain handlers, and processing si

tes that need reliable information before accepting, blending, or processing material.

Samplex Bulk Samplers are built for grain and feed intake applications where accurate, representative sampling is critical. Using

 a gravity-fed UniSpear approach aligned with ISO24333 cereal sampling standards, the range helps teams improve sampling consistency while reducing operator variability.

Common applications include:

• Incoming grain shipment checks
• Feed raw material sampling
• Intake quality assurance and grading
• Contract and compliance sampling
• Safer, more repeatable alternatives to manual collection

Inline sampling for continuous process monitoring

Quality control does not stop at intake. In many facilities, operators also need reliable samples from moving product streams to monitor quality during processing.

Samplex Inline Samplers are designed for installation within elevators, mills, and process lines so teams can collect representative samples without interrupting production. This supports faster decision-making, more consistent monitoring, and a stronger connection between lab testing and live production conditions.

Inline sampling can help teams:

• Monitor process quality in real time
• Reduce manual sampling effort
• Improve consistency across production runs
• Support continuous quality assurance workflows

Pellet durability testing and production performance

Pellet quality has a direct effect on handling, transport, waste, and final performance. When pellets break down too easily, producers can see more fines, more rework, and less consistency in the finished product.

Holmen Pellet Durability Testers are used to measure how pellets withstand handling and transport by simulating real-world wear. The range gives producers fast, repeatable insight into Pellet Durability Index performance so they can monitor quality, optimize press conditions, and reduce avoidable waste.

Holmen systems help support:

• Faster pellet quality checks
• More consistent production monitoring
• Reduced rework and wasted energy
• Better control over pellet durability performance

Comparing sampling and testing considerations

When reviewing sampling and testing methods, the most important question is not simply how fast a check can be completed. It is whether the method produces representative, repeatable results that operators can trust in real working conditions.

Teams often evaluate solutions based on:

• Whether samples reflect the full load or product stream rather than one isolated point
• How consistently the method performs across operators, shifts, and sites
• Whether testing supports day-to-day production decisions, not just occasional verification
• How easily the equipment fits into existing intake, processing, or quality workflows
• Whether the process helps reduce manual effort, variability, and avoidable rework

A strong approach to post-harvest quality control usually combines sampling accuracy, testing repeatability, and practical fit within the operation.

Insect detection in stored grain 

Stored grain quality can be compromised quickly when insect presence goes unnoticed. Early detection matters because it helps operators isolate risk before it spreads through a storage or handling system.

The Insectomat Insect Detection System is designed to screen grain samples for live insects in cereals such as wheat, oats, and barley. For storage operators, grain merchants, and quality assurance teams, fast screening can support earlier intervention and better protection of stored product quality.    

A connected approach to post-harvest quality control

Sampling, testing, and inspection are most effective when they work together. TEKPRO’s post-harvest portfolio is built around the practical needs of feed mills, grain handlers, food processors, and quality teams that need dependable equipment across multiple stages of operation.

By combining bulk sampling, inline sampling, pellet durability testing, and insect detection, TEKPRO supports a more complete quality assurance workflow across the post-harvest chain.
