Between Deepavali on 8 November and Chinese New Year and Tet on 6 February 2027, Southeast Asia's roast meat shops live through ten weeks that decide the whole year. Banquet orders stack up, families order whole birds for reunion dinners, and the shops that planned their capacity sell out their best week — while the shops that did not stand at the oven at midnight turning customers away. Capacity planning is not a big-business concept; it is four numbers and a calendar.
We build roast duck and roast pig ovens in Zhongshan, Guangdong, and ship them to Malaysia, Indonesia, Vietnam, Thailand and Cambodia. Every January we get the same calls: the oven was fine in October and now it is drowning. This guide is the planning conversation we usually have with customers in November, written down. The numbers are typical values from real customer setups — your birds, your staff and your city will move them, so run one festival week with a notebook, not from memory.
The season, market by market
| Festival | Date | Where it bites | What sells |
|---|---|---|---|
| Deepavali | 8 Nov 2026 (holiday 9 Nov) | Malaysia and Singapore; Indian communities region-wide | Roast chicken and pork for open houses; banana-leaf restaurants run extra volume |
| Christmas and New Year | 24 Dec – 1 Jan | All six markets — hotels and company annual dinners | Whole roast pigs and banquet trays, booked weeks ahead |
| Winter solstice | Around 21–22 Dec | Chinese communities everywhere | Roast duck for family dinners — a small spike, easy to miss |
| Chinese New Year | 6 Feb 2027 | Malaysia, Thailand, Cambodia, Indonesia | Everything; the final week often runs 2–3× an ordinary week |
| Tet | 6 Feb 2027 | Vietnam | Whole roast pig for ancestor altars; cured meat demand peaks weeks earlier |
Two details matter as much as the dates. First, festival orders close early: shops in Malaysia commonly stop taking CNY whole-bird orders once deposits cover the oven's realistic output, which can be a week before the day. Second, Tet pulls everything forward in Vietnam — sausage and cured meat are needed in December, so a Vietnamese shop's peak starts a month before everyone else's.
Do the math in birds, not feelings
Start from the oven, but do not stop there. A typical gas roast duck oven takes 28–64 birds per batch at 200–230 °C for 60–75 minutes, plus 15–20 minutes to unload and reload. On paper a 40-bird oven running back-to-back in a ten-hour day could push 250 birds. In reality one roaster who is also hanging, scalding and serving the counter manages three full batches comfortably and a fourth only with help. Plan your ceiling at 80% of the paper number: three batches of 40 is 96 birds, and 96 is the number you can promise.
- Oven ceiling. Realistic batches per day × birds per batch. Write down what you actually did last peak week, not what the brochure says.
- Drying throughput. Birds per cabinet load × loads per day. If skin-set takes 6 hours, a 60-bird cabinet gives you an overnight load plus one midday load — 120 birds a day, and the timing has to be scheduled like a train timetable.
- Scalding throughput. One bird per 2–3 minutes means 120 birds is 4–6 hours of one person's time. It has to happen in waves the evening before and before dawn.
- Chiller space. Marinated birds hold 24–48 hours at 0–4 °C. Peak week you are roasting birds marinated yesterday — make sure yesterday's birds physically fit.
Say your target is 120 ducks on the busiest day. The oven runs three batches of 40: first load in at 4:30 and out by 6:00, second at 6:30, third at 9:00. The drying cabinet takes an overnight load of 60 for the first two batches and a second load of 60 at midnight for the third. Scalding happens in two waves — 60 birds at 20:00 the night before and 60 at 2:00. Marinated birds wait in the chiller in two shifts. None of this is difficult, but every wave needs a person assigned to it on paper before the week starts, because at 5 a.m. on festival morning there is no time to design a workflow.
The bottleneck is almost never the oven
When a shop turns customers away during festival week, the oven usually has room left — the drying stage does not. Ambient air-drying depends on the weather, and December to February is exactly when tropical humidity sits at 85–95% with afternoon rain: skin dries unevenly, glaze slides, and crackling goes leathery. A drying cabinet holding 40–80 birds at a controlled 50–60 °C turns skin-set into a fixed 4–6-hour step you can schedule. The second silent bottleneck is the counter: hanging and unloading birds is slower than the roast itself, which is why shops that add a second pair of hands for festival week sell more than shops that buy a second oven.
Gas runs out at the worst moment
A duck oven burns about 2 kg of LPG per hour. Three long batches plus preheat is roughly 4–5 kg a day, so festival week means a cylinder change almost daily — keep a full spare, a working changeover regulator and the gas supplier's holiday phone number on the wall.
A six-week countdown for the big week
- Six weeks out. Order equipment and spare parts now. Factory production runs 2–3 weeks and sea freight to Port Klang, Ho Chi Minh City or Bangkok adds 2–3 weeks more — an oven ordered in November lands mid-December; ordered after early December it usually lands after the festival you wanted it for.
- Four weeks out. Service the oven: clean the burners, check the flame burns blue and even, test the thermostat against a probe thermometer, inspect the door seal. Order the spares kit: one heating tube, one thermostat, a gas regulator and hose, a door gasket and 20 extra hooks.
- Three weeks out. Open pre-orders with deposits and cap them at 80% of your planned capacity. Deposits tell you the real number, fund the extra stock, and mean zero waste if the week runs short.
- Two weeks out. Train the second roaster and run one full dress rehearsal — scald, dry and roast a complete batch on festival-day timing, then fix what went wrong while there is still time.
- Final week. Post the roast schedule on the wall: marinating waves, scalding waves, load times. Festival morning should be execution, not decisions.
One more lead-time note, because it is the most expensive mistake we see: equipment ordered in November still arrives in time for Chinese New Year; ordered mid-December it is a coin toss with customs and sailings; ordered in January it is next year's machine. The same applies to spare parts — a burnt heating tube on the second day of festival week is a closed shop, and a USD 30 tube mailed in advance is the cheapest insurance in this business.
The five things we ask before quoting a peak-season setup
When a shop owner messages us about festival capacity, we never answer with a price first. We ask:
- How many birds on your busiest day — and how many did you turn away last year? The second number is the one that pays for the upgrade.
- Gas or electric, and what voltage? 220 V single-phase runs small cabinets; larger ovens and some cabinets want 380 V three-phase, which many shoplots do not have.
- Who roasts festival week? One trained person or two? This decides whether an automatic rotating oven pays for itself in a single season.
- How much chiller space? Peak week lives or dies on prep storage, not roasting.
- Which port or city? Freight and lead times are part of the quote, not an afterthought.
The shops that sell out their best week are not luckier or busier — they decided in November what festival week would look like, wrote the numbers down, and bought or serviced what was missing. The ten weeks pay for the year; plan them like it.
