Where a Biscuit and Confectionery Plant Loses Money in India

A mid-size biscuit plant rarely loses money in one big breakdown. It loses it in small amounts around a tunnel oven that cannot pause: late starts, packing stops while the oven keeps baking, broken biscuits, a few grams of overfill on fixed-price packs, and changeovers that overrun. On the illustrative 800 kg/hour line below, these leaks add up to roughly ₹54,000 a working day in peak season and about ₹30,000 a day when you are not sold out.

By the Mama Editorial Team. This is an overview for owners and directors of biscuit, cookie, wafer and sugar-confectionery plants with roughly 200–1000 people. It shows where the money goes, which leaks to chase first, and which of them a camera can actually help with. The figures are worked assumptions unless a source is linked, so put your own numbers in before you trust the total.

Key takeaways

• The oven is the pacemaker, and it doesn't stop. One US oven maker describes its tunnel ovens as typically 60–90 m long with 3–6 zones (Reading Bakery Systems, US DOE workshop, 2023). Whatever is inside when packing stops still comes out baked.
• A packing jam on a biscuit line costs more than it does on a snack line. On a standalone packer a stop only loses minutes. On a biscuit line it also turns good biscuits into broken ones.
• On fixed price points, giveaway comes straight out of margin. Makers "rarely move away from the ₹5, ₹10, and ₹20 price points" and cut grammage instead (Agro & Food Processing, 2021). Each gram over declared weight is product you give away.
• Breakage often starts after the oven. Hairline cracks ("checking") form as biscuits cool and make them likely to break later during packing and transport (UK Loughborough University study of semi-sweet biscuits, reported by BakeryandSnacks, 2003).
• Time-based leaks are what cameras catch well: late starts, empty oven band, idle packers, long changeovers and sanitation overruns. Weight, moisture and bake colour need instruments, not CCTV.

How a biscuit line makes money, and why it leaks

A biscuit line is one coupled chain: mixer → sheeter or rotary moulder → tunnel oven → cooling conveyor → stacking → flow-wrap or pillow pack → cartons. The oven sets the line's output, and it is the one machine you cannot stop and restart in a minute. Its zones take time to come up to profile, and once dough is on the band it bakes on a fixed clock.

The result is lopsided: every stop downstream of the oven turns into product, not just lost time. When a wrapper jams, biscuits pile up on the buffer table, get hand-packed, or end up in the broken bin. When the oven starts late, the whole packing hall waits. For the packer side alone, see FFS packing machine micro-stops.

The eight places the money goes

1. Oven start-up and the first bakes. The oven comes up to temperature late, the first trays come out pale or dark, and the band runs empty while the dough room catches up.

2. Packing stops while the oven keeps baking. This is the leak specific to biscuits. Say a film splice or a stuck pack stops the flow-wrapper for 90 seconds. In that time the oven keeps delivering, and on the line below that is about 20 kg. Some of it is hand-packed later and some becomes broken.

3. Breakage and checking. Some breakage is mechanical: transfer points, stacking, drops at the packer infeed. Some is built in during cooling. In the Loughborough work, published in Measurement Science and Technology, the rim of a cooling biscuit picked up moisture and swelled while the centre dried and shrank, and the strain was released as cracks (BakeryandSnacks, 2003). For you, a cooling problem looks like a packing-hall breakage problem.

4. Giveaway. Packs filled above declared weight to stay safe. On a ₹10 pack you cannot pass the cost on. When palm oil and packaging costs rose in 2021, Parle cut the grammage of its ₹5 and ₹10 biscuit packs rather than move the price (Agro & Food Processing, July 2021). Grams are the lever, so every gram of overfill matters. The formula and the Legal Metrology floor are covered in product giveaway in Indian food packing.

5. SKU and flavour changeovers. Moving from glucose to cream, or from 100 g to 50 g packs, can mean a moulder roll change, a new oven profile, a wrapper reel and print change, and a coder update. The stopped time is visible. The slow, reject-heavy first hour afterwards usually isn't. See SKU changeover on Indian packing lines.

6. Sanitation overrun. Cleaning is required. The loss is the gap between the planned clean and the actual one, and it hides inside "planned downtime". Sanitation-adjusted OEE for food lines shows how to separate the two.

7. Wrapper film waste. Start-up and splice waste, misregistered print, date-code errors. Under the FSS (Labelling and Display) Regulations, 2020, the date of manufacture or packing and the expiry/use-by date are mandatory on pre-packaged food, and "best before" is optional (FSSAI labelling compendium, reg. 5(10)). A pack with a smudged or missing date can't be sold.

8. Packing-crew waiting. The packing hall holds most of your headcount. When the oven starts late or the line stops, 30–50 people wait together.

Worked example: one line, one day, in rupees

Assumptions (illustrative; replace with yours): one tunnel-oven line baking a glucose-type biscuit at 800 kg/hour (13.3 kg/minute). For scale, one US oven maker quotes its biscuit, cookie and cracker lines at 1,000–5,000 lb/hour, about 450–2,300 kg/hour (Reading Bakery Systems, US DOE workshop, 2023). Two 8-hour shifts, so 12,800 kg is planned a day, packed into 100 g packs. Assume:

• ₹20/kg contribution on a kilo you could have sold, if you were sold out
• ₹35/kg lost on a kilo downgraded to broken (dough or broken-biscuit sale recovers part of it; the conversion cost is gone)
• ₹60/kg cost of a kilo given away as overfill
• a 40-person packing crew at ₹500/day all-in, about ₹62/hour. This is illustrative only; use your state's current minimum-wage notification for your trade and skill level, which most states revise twice a year.

Over 26 working days that comes to roughly ₹14 lakh a month at festive peak and ₹7.8 lakh in a slack month. Two things matter more than the total:

• The ranking shifts with the season. When you are sold out, lost hours (slow start, changeovers, sanitation) lead the list. When you are not, giveaway and broken product do, because lost hours then cost only gas and wages. Before Diwali, recover these hours before you add a third shift.
• Broken biscuits are paid for twice. A downgraded kilo has already used up its flour, fat, sugar and its oven energy. For scale, the same US oven maker puts the gas used to bake hard and soft cookies on US lines at about 500 BTU per pound, roughly 1.16 MJ per kg (Reading Bakery Systems, US DOE workshop, 2023). On that US figure, each tonne that goes to the broken bin has burned about 1.2 GJ of oven gas as well as using up the ingredients. Your own oven's gas meter gives the real number.

If you also run confectionery

Toffee, hard-boiled candy and éclair lines follow the same logic with a different pacemaker. The points below are general process practice, not figures from a study. The cooker and the forming or depositing stage set the rate, and the twist-wrap or flow-wrap at the end is where short stops build up. Two differences matter:

• Sugar mass waits less patiently than dough. If forming or wrapping stops, the cooked batch starts to set. You remelt it or scrap it, so a wrapper stop costs product and energy again.
• Humidity is a production variable. Sugar confectionery is hygroscopic, so on monsoon days pieces stick in the wrapper and stops rise. Log stops against the weather before you blame the crew or the machine.

What cameras can and cannot see here

Pointed at the right places, cameras show:

• Empty oven band at the exit. A gap in the biscuits coming out is lost output you can see directly, and you can measure how long it lasts.
• The real start time. The first saleable biscuit reaching the packers, as opposed to the time written in the shift book.
• Packers stopped while biscuits pile up on the buffer table, and how often and for how long this happens each shift.
• Broken-bin fill at the packer infeed, as a rough daily trend.
• Changeover and sanitation start and end, measured against your standard.
• Packing-hall crew counts, idle versus working. Counts only: no names, no operator ranking.

They cannot:

• Weigh a pack. Giveaway needs a checkweigher and its records.
• Measure moisture, bake colour or hairline checking. These need lab tests and inline instruments, not CCTV.
• Read oven zone temperatures. The oven's own controls and logger do that.
• Prove FSSAI compliance or food safety. Video gives context to your QA records; it doesn't replace them.
• Tell why a wrapper stopped when the cause is inside the machine. The PLC alarm log shows that, and the two sources work best together.

If footage shows identifiable workers, treat it as personal data. Put up a clear notice and set a retention limit before you switch anything on: see the worker CCTV notice under DPDP.

Where to start this month

1. Time the start. For one week, note when the oven reaches profile and when the first saleable pack comes off. The gap between that and the plan is your first figure.
2. Weigh the broken bin each shift. A month of daily kilos shows whether breakage comes from cooling, transfer points or packing stops.
3. Pull a week of checkweigher data. Work out average overfill per SKU and convert it to rupees. Get the target signed off against the Legal Metrology rules before you move it.
4. Write down a standard for each changeover type, then record the actual time against it.

Where Mama fits

Mama reads the cameras a plant already has, or a few added at the oven exit and packing hall. Each morning it sends the owner a short plain-language note on where hours went yesterday: late start, empty band, packers stopped, changeover and cleaning overruns. It watches machines and product flow and counts people in aggregate, without naming or ranking anyone. Mama can draw a camera plan for your oven exit and packing hall.

FAQ

What is the biggest hidden loss in a biscuit plant? It depends on whether you are sold out. In peak season, lost hours at the oven (slow starts, changeovers, cleaning overruns) usually cost most, because every hour is unbaked product you could have sold. In slack months, giveaway and broken product usually lead, because lost hours then cost only gas and wages.

Why do biscuits break even when the packing machine is set correctly? Some cracks form before the biscuit reaches the packer. Research at Loughborough University found that uneven moisture during cooling causes hairline "checking" cracks, which make biscuits fragile when they are later packed and transported.

Can a camera measure giveaway or pack weight? No. Pack weight needs a checkweigher. A camera can show when the line ran, stopped or changed over, which helps explain checkweigher trends, but it cannot weigh anything.

Does FSSAI require CCTV in a biscuit plant? Not as a general rule, as far as we can confirm. We found no blanket FSSAI direction making CCTV mandatory for food manufacturers, including biscuit and confectionery plants. FSSAI's Schedule 4 mandates hygiene practices rather than cameras (see cameras in food processing plants under FSSAI). FSSAI also sets record-keeping and labelling duties, including mandatory manufacture/packing and expiry/use-by dates on packs. Check your licence conditions, any state or category-specific order and buyer-audit requirements separately.

How do I compare two lines fairly? Compare saleable kilos per oven hour, broken kilos per tonne baked, and average overfill per pack, all over the same weeks and SKU mix. Rupees per tonne is a fairer basis than "efficiency %" because it includes breakage and giveaway, which time-based efficiency figures leave out.
