Third shift is when most food plants clean, and it is also when line status is hardest to see. Lines are torn down at different times, crews move between wash bays, and QA is swabbing one line while another waits for a pre-op check. The whiteboard by the sanitation office is out of date within the hour. A sanitation kanban board gives every line clean its own card that moves from teardown to release, with ATP swab results and sign-offs attached. See a board built from real line cards in a short sanitation board demo.
Every Line Clean on One Board, From Teardown to Release
iFactory Sanitation Kanban gives each line clean its own card, with columns for teardown, wash, inspect, swab and release. Crews move cards by voice from the wash floor, and ATP results attach to the right card automatically.
Six Columns Built Around the Wet Clean
Most wet cleans follow the same seven steps: dry clean, first rinse, soap and scour, post-rinse and inspect, reassemble, pre-op, then sanitize. The board does not replace your SSOPs. It groups those steps into columns so anyone can see where each line stands, and it makes every move depend on evidence instead of a shout across the floor. A Scheduled column holds cleans from the master sanitation schedule before teardown begins. Map your own SSOP steps to columns with our sanitation specialists.
The step names follow the widely used seven-step wet sanitation model published for the dairy industry. Your SSOP wording, order and chemistry may differ, and the columns follow your SSOP.
The Whole Night on One Screen at 02:40
A plant manager should be able to look at the board once and answer three questions: which lines are behind, where cards are waiting and which lines will be ready for first shift. Each card is one line clean. Its column shows the stage, its age shows how long it has waited, and flags mark allergen cleans and swab points that need a re-clean. The snapshot below is an illustration of a seven-line night. See the same view on your own lines in a live board walkthrough.
Pass, Caution and Fail Limits Belong to Your Site
ATP testing measures organic residue left on a surface and reports it in relative light units, or RLU. There is no universal pass mark. Readings depend on the luminometer brand, the surface type and its condition, so worn, pitted steel reads differently from new stainless. Instrument makers ship default limits, and at least one, Hygiena, recommends each site sets its own limits per surface. When a reading arrives, iFactory compares it with the limit for that swab point and moves or holds the card. Set up your swab points with our QA support team.
Swab Results That Find Their Own Card
With iFactory, a luminometer reading lands on the right line card as soon as it is taken. Passing points tick off, cautions and fails send the card back with the point named, and crew leads report re-cleans by voice.
ATP Is Not an Allergen Test
A low ATP reading shows little organic residue. It does not show that an allergen protein is gone, because ATP is present in all living and once-living cells and is not a reliable marker for allergenic protein. Allergen changeover cleans need extra gates: a close visual check and an allergen-specific test, such as a lateral flow swab, for the allergen just run. Under FSMA, preventive controls cover both sanitation and allergen cross-contact. On the board, an allergen card cannot reach Release until those gates are met. Configure allergen gates in a changeover board session.
The card carries the allergen from the product just run, taken from the production schedule, so the swab kit matches the risk. Use ELISA or your lab method for rinse water or first product where your allergen plan calls for it.
WIP Limits Set by Crews and Kit
A WIP limit caps how many cards may sit in a column at once. On a sanitation board the right limit usually comes from a physical constraint: how many crew pairs are on shift, how many foam and rinse stations can run together and how many QA techs can swab. If three lines are in Wash with two crews, one line is really waiting, and the board should say so. When a column is full, the next card waits upstream, so the bottleneck is plain to everyone. Work out limits for your shift with our support team.
Pre-Op and Release Sign-Off Checklist
The last move on the board, from Swab to Release, is the one that matters most. Use this checklist as a starting template for the release gate and adjust it to your SSOPs and food safety plan. Every item ticked here is stored on the card with who checked it and when. Walk through it on your own line in a release gate demo.
Wet Gloves, Loud Floor, Spoken Card Moves
Sanitation crews work in wet PPE with hoses running. Stopping to wash hands and type on a handheld is the reason most boards fall behind. With voice, a crew lead speaks the line and the stage, iFactory reads the move back, and the card moves only after the lead confirms. Hear how it sounds on a noisy wash floor with our voice specialists.
From Whiteboard to Live Board in Four Steps
Start with one shift and the lines that most often miss their start time. Keep the whiteboard up while the board proves itself, then retire it once crews trust the cards. Plan the rollout with a sanitation rollout session.
Count the Minutes Lines Wait to Be Released
The clearest value is the time between a line being clean and being released, plus re-cleans found late instead of early. Use your own figures. The worksheet below uses assumed inputs only to show the arithmetic. Our support team can help you size it with your own shift data.
Sanitation Board and Edge AI Server, Shipped Ready to Run
iFactory delivers Sanitation Kanban as a turnkey package. A pre-configured NVIDIA AI server ships racked and ready, with the board, voice agent and swab result import pre-loaded, so speech is handled on site and works through the noise of a wash floor. You rack it, plug in power and Ethernet, and the AI is live. Scope it for your plant with a turnkey quote.
