Every poultry processing plant is specified around one core number: birds per hour, or BPH. It is the industry-standard way of describing how much a line can process, and it drives almost every other decision — machine selection, floor space, manpower, and budget. Getting this number wrong in either direction is an expensive mistake, so it is worth slowing down before you buy.
Start with your real volume, not your ideal volume
The starting point is your actual current slaughter volume — daily and weekly — not an aspirational figure. From there, look at your shift pattern: a plant rated for 1000 BPH over a single 8-hour shift can process far more per day if you run two shifts, so the machine capacity and your daily output are two different numbers that are easy to confuse.
Plan two to three years ahead, not just for today
Processing lines are not simple to expand once installed — scalding tanks, conveyor lengths, and chiller capacity are all sized to work together, and upgrading one stage without the others just creates a new bottleneck. If you expect meaningful growth in the next two to three years, it is usually more economical to size the plant for that future volume now rather than replacing equipment twice.
Match automation level to your capacity, not the other way around
Semi-automatic setups — individual stations like a Hy-Cab cabinet unit or a hybrid line with an overhead conveyor — comfortably handle 200 to 600 birds per hour and suit operations that are scaling up or working with more manual labour. Fully automatic conveyorized plants are built for continuous higher-volume runs, from 500 BPH up to 4000 BPH, and make sense once volume and consistency requirements justify the higher automation.
Do not let one stage bottleneck the rest
A common sizing mistake is over-specifying the kill and scald stages while under-specifying downstream stations like chilling or portioning. A line is only as fast as its slowest station — before finalising an order, check that the capacity of every stage in the line is matched, not just the headline BPH figure of the plant.
Get a second opinion on your numbers
If you are unsure which capacity band fits your operation, it is worth running your numbers past someone who sizes these lines regularly rather than guessing. Our team reviews capacity requirements as part of every quotation, at no cost.
