If your poultry plant already uses an industrial inline tray sealer that carries preformed trays into the sealing station, you can add automatic weighing and filling at the tray infeed. The Smart Weigh LC12 linear belt combination weigher lets operators load chicken by hand while the machine weighs the pieces, selects a portion and automatically discharges it into a tray. This can help you fill more trays per minute with the sealer you already use.
How the LC12 takes over weighing and discharge
When weighing by hand, an operator might fill a 500 g tray, read the scale, swap a piece and weigh the tray again. With the LC12, the operator places individual pieces or small amounts of chicken on the 12 weighing belts. Each belt is weighed separately. The controller chooses the combination that best meets the set weight within the permitted range. The selected belts move the chicken onto the collection belt, which delivers the weighed batch to the waiting tray.
Manual loading onto the belts → automatic combination weighing → automatic discharge into a tray → tray conveyed into the existing sealer
Operators still separate the pieces and keep enough belts loaded. If the customer requires a particular arrangement of wings or drumsticks in the tray, an operator can arrange them before sealing. View the Smart Weigh LC12 linear belt combination weigher.
Why semi-automatic weighing costs less upfront
Keeping manual loading of the chicken saves the upfront cost of an automatic product feeder. Reusing the inline sealer lets you keep the machine and tray tooling already in use. The upgrade can be limited to the LC12 and the parts and controls needed to connect it to the existing tray infeed.
How the LC12 connects to your inline tray sealer
At Smart Weigh Indonesia, we design the LC12 discharge height, direction and position around your sealer's infeed. The aim is to fill each tray at a defined point before it enters the sealing station. The layout depends on how your sealer receives trays.
- Fill at the existing infeed. If the conveyor or tray carrier can position an empty tray reliably under the outlet, we align the LC12 discharge with that point. The existing infeed then carries the filled tray into the sealer.
- Add a short tray conveyor before the sealer. If the existing infeed has no suitable filling position, a short indexed conveyor can stop each tray under the LC12 outlet, then transfer the filled tray to the existing infeed.
We check tray spacing, usable tray opening, outlet clearance and access for cleaning. We also look at where the chicken lands. A drumstick across the tray rim may need to be repositioned before sealing. During integration, we confirm how the LC12 detects that a tray is in position and how it holds the next portion when the infeed cannot accept another tray. If the sealer takes several trays per cycle, we match the transfer to the spacing and tray sequence it requires.
What to confirm with your chicken and trays
Ask for a trial with the poultry cuts, target weights and tray formats you run most often. The output you can expect depends on how quickly operators can replenish the belts, how often the weigher finds a suitable combination and how quickly the line can receive and seal the filled trays.
Large whole pieces can limit the combinations available for a tight weight range. If a 500 g tray must also contain exactly four drumsticks, include that count in the trial requirements. Check the filled trays for weight variation, overfill and any pieces that still need hand adjustment before sealing.
