How much milk came in
and how much is left

The weight of every silo, read three times a second, from delivery to vat.

Supervision and control system for dairy plants

Continuous supervision of the tanks of a dairy plant. Weight comes from the load cells, becomes litres, and every change leaves a line: who, when, how much. What enters from the intake bay and what leaves towards the vats are reconciled every evening.

Purpose

A single view
for all the stored milk

Every silo rests on load cells. The system polls them without stopping, converts weight into litres with the specific gravity of the product and keeps count of what goes in and what goes out. When the weight moves with no operation open, it says so.

01 Weight

What the load cell really says

No one types a number. The instrument reads the weight, stored with the time to the second.

  • stable weight flagged by the instrument
  • kilograms and litres together, per product
  • fill percentage and free space
02 Movement

Loadings and discharges detected

When the stable weight moves past the threshold of the silo, the system records a loading or a discharge without being told.

  • separate thresholds for loading and discharge
  • start weight, end weight and difference
  • unexpected changes flagged at once
03 History

A line for everything that happens

Deliveries, discharges, alarms, overrides and corrections stay written. Prints and summaries come from there.

  • search by day, by silo, by supplier
  • reports with the company heading
  • export to Excel from every list
The overview

How a day goes

From tankers
to the vats

Milk comes in early in the morning and starts to leave before the deliveries are over. In between there is a silo filling up, a blend that changes and a weight that must never move on its own.

  1. 01

    The tanker arrives

    Supplier and silo are chosen. Certificates are checked before opening.

  2. 02

    Discharge

    The weight rises and is seen rising. At the end: kilos, litres, temperature.

  3. 03

    The sample is taken

    The tube stays tied to those kilos, with fat and protein.

  4. 04

    On to the vat

    Discharge is followed by weight: at the kilos asked, it stops.

  5. 05

    The day is closed

    Inputs, outputs and stock are compared. What does not add up stays.

The day’s operations
The day’s operationsIn time order: what came in, what went out, who was there and how it ended.
Every step leaves its trace

No step is recorded from memory or at the end of the shift: each line is born when the weight moves.

A typical day: 4 deliveries · 25,010 kg in · 13,720 kg out · 2 changes to explain
On the left the bridge net, on the right the kilos into the silo, in the middle the difference and the verdict. Below, all recent deliveries with both weights.

Weighbridge vs silo

Two instruments
for the same milk

The tanker weighs on the bridge in and out: the difference is what the driver says was delivered. The silo, meanwhile, weighs what really came in. The two numbers are compared on their own, delivery by delivery.

The delivery just closed

Toleranceset as a percentage; below that threshold the delivery closes with no one stepping in
Out of tolerancethe line stays open until someone writes the reason: it cannot be deleted
Questions, in ordertanker fully emptied, milk split into two silos, discharge open at once, cell to calibrate
Month enddifferences above tolerance go into the supplier statement, with their explanation

Weighbridge required

The system talks to the bridge indicator as it talks to the silo cells. Without a bridge this page is not used and everything else works the same.

What is found

A tanker not fully emptied, a leaking hose, a cell out of calibration. These are kilos otherwise found at month end, when the figures no longer add up.

The thirty screens

Thirty screens
one for each job

The pages of the system, grouped by job: the intake bay, the milk in store, the suppliers, the controls, what you look at away from the office, and the settings.

Intake

Loading opens only if it may open

The intake bay station is used with fingers, with gloves on. Supplier and silo are chosen, and before the pump starts the system looks at the health certificates of that farm.

The intake bay
03The intake bayLoading under way: the weight rising, the kilograms taken in so far, the sample and the tanker’s delivery note.
The refused load
04The refused loadAn expired certificate stops the load before the pump starts. The reason is written in plain words and only a supervisor can release it, with a badge.

Before opening

The four certificates

Leucosis, tuberculosis, brucellosis and dioxin: each with its expiry. If one expired, loading does not start.

  • supplier notified thirty days before
  • block at expiry, no automatic exceptions
  • override only by the supervisor, and written
While loading

The weight stays in sight

What has come in so far and the room left in the silo are shown. At the close the system writes kilos, litres and temperature.

  • start and end weight of the silo, from the cell
  • sample and tube number tied to the loading
  • the operator signs with the badge, not a pen

Silo by silo

What is inside and for how long

From the overview a single silo opens. The card puts together the weight now, the curve of the last twenty-four hours, the deliveries that make up the blend and the date of the last CIP wash.

The overview
01The overviewThe six silos on one screen: level, kilograms, litres and temperature. At the foot, the day and the time at which, at this rate, each silo runs out.

Weight variations
06Weight variationsEvery movement detected by the instrument, with starting weight, final weight and difference. Lines with no operation open stay in view.
The balance
09The balanceIn, out and stock silo by silo, with the difference in kilograms and per cent. Whatever does not add up stays written down.
The week’s levels
10The week’s levelsSeven days of levels, one silo per row: you can see which one works full, which stands idle and at what time it fills.
The batch
11The batchWhich deliveries the milk now leaving is made of: the bands say how much milk belongs to whom, hour by hour.
The washes
12The washesThe CIP cycles of the six silos: when they were run, how long they lasted and at what temperature. An interrupted cycle stays red.
The cold chain
25The cold chainOne curve per silo over twenty-four hours, each with the limit of its own product. Below, every excursion with its reason.

The level is seen, not computed

The drawn tank fills with the real weight. The percentage comes from the capacity set for that silo.

Litres and kilograms

Each product has its specific gravity: cow milk, buffalo milk, cream and whey do not weigh the same.

How long the milk has sat

Holding time starts from the oldest delivery still in the blend and helps decide what to process first.

Below minimum shows at once

Each silo has its threshold. When weight drops below, the card changes colour and the alert starts.

The cold chain

Temperature next to weight

Each silo can have its probe. Temperature is recorded on its own, every minute, and sits on the same line as the weight: milk standing warm is seen as it happens, not at day end.

  • Readingone a minute, for each probe
  • Limitper product, not the same for all
  • Alertafter a quarter hour above the limit
  • Recordcurves stay, month by month
Under every silo there are load cells: every number on this page comes from there.

Suppliers

Who brings milk with what papers

For each farm there are the municipality, the head of cattle, the four health certificates with their expiry dates and the whole history of deliveries. The intake bay reads from here, with nothing to ask.

To the supplier

The sheet the milk is paid on

At month end, for each supplier, the delivery statement comes out: day by day the kilograms, litres, fat and protein, with the weighted averages of the month. The kilograms are those of the cells: not a single figure is written by hand.

Statement

Starts on its own, on the day set

One PDF per supplier, all together, with the e-mail already prepared.

  • refused deliveries and reason
  • bridge-to-silo differences over tolerance
  • amounts come from the ERP, not from this system
The portal

Optional, and asks for nothing

Those who do not use it keep getting the statement by post, as always. Those who use it also find past months.

  • each supplier sees only their deliveries
  • new certificates are uploaded there
  • no other dairy plant data is visible

The controls

What happened and who saw it

The alerts with their thresholds, the monthly control record, the chain behind a recall, and the log of who did what.

The recall
27The recallWhere one supplier’s milk ended up: the silos, the vats, the batches that came out and the customer notes to be called.
The control record
28The control recordThe monthly file as it comes off the printer: temperatures, washes, certificates and the non-conformities signed off by whoever closed them.
The alerts
13The alertsThe thresholds of each silo, who the alerts reach, and the night watch with its own hours.
The notifications
14The notificationsThe notification centre and the day’s log: what went out, to whom, and when it was read.
The event log
21The event logWho signed in, what they did and from where. The system’s own lines sit next to those of the people.

The control record

The monthly dossier fills itself in

Temperatures, CIP washes, certificates checked at the bay, holding times, bridge-to-silo differences: all lines already written by the system. At month end they become a ready dossier, with the non-conformities and who closed them.

No one copies anything

The record lines are the same ones the system wrote day by day, from the probes and the cells. There is no second step where a mistake can happen.

Each non-conformity closes

A breach of limits stays open until someone writes what happened and what was done. The name stays next to the line.

When needed, not only at month end

The dossier can be asked for any period, and in any of the five languages of the program.

The dossier preview: the summary of checks and, below, the non-conformities of the month one by one.

Outside the office

The same view by the vats and on a phone

The program is a page: it opens on a tablet in the plant and on a phone with the same address and the same password. There is nothing to install and, if a device breaks, another one is used.

Reports that go out alone

The milk of the day, silos below minimum, certificates expiring, unexpected changes: each with its time, its recipients and its attachment.

The settings

The silos, the products and who may do what

Set once and it stays: the capacity and thresholds of each tank, the rules of each product, the operators’ badges, the printouts and the devices.

Diagnostics

Weight indicators

They connect on the network, one per silo. The system recognises the protocols most common in industrial weighing plants and also reads the stable weight state.

Temperature probes

One per silo, read on the same round as the cells. Where there are none, the silo still works: only the cold curve is missing.

Weighbridge

It serves to compare the two weights of a delivery. It connects like the other instruments, with its address and its port.

If something goes silent

After a few seconds of silence the weight is unreadable on screen, the alarm sounds once and the silo is marked stopped. When the instrument returns, it resumes alone.

Nothing holds the last good valuean old weight shown as current is worse than no weight: the system says so
Test on demanda device is polled and what it answers is read, character by character
Printersreports on the office printer, labels on the bay one
Badgethe bay reader signs operations without gloves typing passwords

Quality, yield

What is in the blend

Fat and protein are recorded at the intake bay, with the delivery open. The silo keeps the average weighted on kilograms and uses it to say how much cheese to expect from each discharge.

  • Weighted average
  • Expected and real

The day’s figures

What comes in and what goes out

At the end of the day the system lines up inputs, outputs and stock and does the subtraction. What is over or missing stays written as «unexplained» until someone says what it is.

  • Balance
  • Compare

Washes

A washed silo is a silo that can fill

Each product has its interval between one wash and the next. The system counts the hours, warns before it runs out and, if the wash is missing, no loading opens on that silo.

  • The count of hours
  • The broken-off wash

None of these screens is a drawing: they are the pages of the system, with sample data.

With the plant closed there are no normal changes. Any drop in weight, even a small one, becomes an alarm and reaches the phone of whoever is on watch, with the silo, the time and the kilograms.

When no one is there

At night
the rule changes

With the plant closed there are no normal changes. Any drop in weight, even a small one, becomes an alarm and reaches the phone of whoever is on watch, with the silo, the time and the kilograms.

The log

Every weight change, with its direction

Loadings and discharges detected by the instrument, with start weight, end weight and difference. Lines with no operation open stay highlighted.

Alert

On the phone, as it happens

The alert carries what is needed to decide: weight before, weight now, how long it lasted, who entered last.

Watch hoursthe start and end times are set, and they hold all day on days of shutdown
Night thresholdlower than the daytime one: at night thirty kilograms are enough to sound
Who gets itphone, e-mail and siren in the silo room, each with its own switch
What remainsthe alert, the time it was read and the name of who closed it
Weight falling for no reason is why these plants are monitoredThe system accuses no one: it records, alerts and keeps. What happened is decided by people, the next morning, looking at the lines.

If something is wrong

Where that
milk went

A positive result arrives on a batch. The supplier name and the day are typed, and the system answers: which silos that milk entered, what it mixed with, which vats it went to, which lots came out and who they were shipped to.

The plant

What is needed
to make it work

A computer in the office acts as server. The instruments connect on the network. All the rest are pages: they open from any computer, tablet or phone in the plant, with an address and a password.

The instruments talk to the server; people talk to the pages. Between the two there is nothing to install.

Server

An ordinary machine

An office computer with Windows and a database. It stays on and does its round: no machine room needed.

  • the database can sit on the same machine
  • backup with the tools already on site
  • no external service required
Stations

Pages, not programs

Bay, office, vat room, tablets and phones open the same address. A new station is added in a few minutes.

  • the bay is used with gloves, large touches
  • the tablet has nothing to install
  • a station can be tied to its machine, if needed
Languages

Five, in full

Italian, English, French, Spanish and Hungarian: in screens, alerts and prints. The language belongs to the viewer, not to the plant.

  • each operator has one
  • prints come out in the language chosen
  • the monthly dossier follows the same rule
Who logs in, what they may do, what they did. The event log collects everything that changes the numbers: deliveries, overrides, thresholds changed, weight corrections, logins. It cannot be edited or deleted.

Access and log

Each line has a name

Who logs in, what they may do, what they did. The event log collects everything that changes the numbers: deliveries, overrides, thresholds changed, weight corrections, logins. It cannot be edited or deleted.

The log

What happened, and by whose hand

The search is by day, by person, by kind of event. The system’s automatic lines sit beside those of people.

Rights

Each one can do what is needed

Opening a loading, discharging to the vat, recording a sample, overriding an expired supplier, correcting a weight: these are separate switches.

The log serves to rebuild a day, not to watch peopleWhen a number does not add up, the question is the same: what happened at three at night. The answer is already written.

In brief

Three
unknowns today

A silo plant without continuous monitoring leaves three questions always open. They are the same three in every dairy, and the three this system answers with a number and a time.

First

How much milk is missing

Not at month end, when the figures do not add up: at the moment the weight moves.

  • inputs and outputs compared each day
  • bridge and silo compared on each delivery
  • unexpected changes flagged at once
  • differences that stay open until explained
Second

Where a given delivery ended up

When a question arrives on a batch, the answer is already in the system.

  • which silos it entered and what it mixed with
  • which vats it went to and which lots came out
  • which customers those wheels were shipped to
  • a PDF dossier, ready to hand over
Third

Whether the checks were done

Temperatures, washes, certificates and stops are already written: the dossier collects them.

  • one temperature reading a minute, per probe
  • each wash with time and temperature
  • each refused loading with its reason
  • each non-conformity closed and signed
How it startsthe plant is surveyed, silos and instruments counted, and the system tried on two tanks
What stays with the dairythe data is theirs and sits in their database; prints and exports can be taken away at any time
