▌Product Description
The Meatech MT-RGS roller grading and sorting machine separates food products by physical size — diameter and cross-section — using a series of parallel SUS304 stainless steel rollers with a progressively increasing gap from entry to exit. Products placed on the roller bed at the entry end travel forward; as the gap between rollers widens along the length of the machine, each product falls through the gap at the point where the roller spacing matches its minimum cross-section, directing it to a collection lane or conveyor below. At 800 kg to 6 t/h sorting capacity and 7.5 kW power, the MT-RGS handles the full throughput range from small-scale fresh produce packing operations to high-volume industrial poultry and vegetable grading lines.
The 5,000×1,000×1,200 mm footprint is compact relative to the sorting capacity — fitting into the space between a washing line and a packing line in a standard fresh produce facility layout. The machine is fully customisable: roller length, spacing profile, number of grade lanes, and frame height can all be specified to match the specific product dimensions and grade boundary requirements of the application. SUS304 stainless steel construction throughout allows daily high-pressure water cleaning and chemical sanitisation in the wet environment of fresh produce and poultry processing operations. The 380V/50Hz power supply is standard food factory specification.

▌Solution Applications
Solution / Line | Role of MT-RGS |
Poultry cut portion sorting | Separates drumsticks, thighs, and wings by size after cutting — directing small, medium, and large pieces to separate packaging lanes. 800kg–6t/h capacity covers both medium-volume cut-up lines and high-throughput industrial poultry plants. |
Solution 11 — Potato, Onion & Garlic Packing | Primary size grading stage — separates washed potatoes or onions into retail size grades before net-bag or tray packing. Simple, reliable, low-maintenance in the wet fresh produce environment. |
Solution 12 — Fresh Fruit Sorting | First-pass physical size grading before optical sorting — removes undersize fruit from the line before the optical sorter, reducing the load on the more expensive optical system. |
▌FAQ
Q: What is the sorting capacity range of 800 kg–6 t/h and what determines the actual figure?
A: The 800 kg–6 t/h range covers the full product and throughput spectrum the MT-RGS is designed for. Actual throughput for a specific installation depends on product size and density (smaller, lighter products move through the roller gaps faster — higher throughput per unit time; larger, heavier products move more slowly); roller spacing (wider gaps allow faster product movement); and the number of grade output lanes (more lanes require longer roller sections per grade, which limits linear throughput speed). For potato grading at standard fresh produce bulk density, typical throughput is 3–5 t/h. For poultry portions, typical throughput is 800 kg–2 t/h depending on piece size.
Q: How is the roller spacing profile specified when ordering?
A: Provide Meatech with: the minimum and maximum product cross-section dimension you need to grade; the number of size grade categories required; and the target size boundary between grades (e.g., small = below 60mm diameter, medium = 60–80mm, large = above 80mm). Meatech's engineering team calculates the roller spacing progression and confirms the roller configuration drawing for your approval before manufacture. Lead time for a custom roller set is typically 2–3 weeks from drawing approval.
