Quick Answer
A hamburger machine presses loose mince into patties of fixed diameter and weight, interleaved with paper discs. UK machines commonly use 100mm and 130mm moulds; a 100mm × 15mm patty is roughly 110–120g. Expect £160–£280 for a table-top manual press. Use coarse chuck at about 20% fat, kept below 4°C.
Caterzone supplies hamburger machines and burger presses to UK burger bars, pubs, and takeaways, and the case for one is simpler than most equipment purchases: portion control. Hand-formed patties vary by 20–30g either side of target, which means inconsistent cook times, unpredictable food cost, and a burger that is different every time a customer orders it.
This guide covers how burger presses work, patty sizing and weight, mince specification, UK food safety for minced meat, cleaning, and costs, so you can choose the right hamburger machine for your kitchen.
What does a hamburger machine do?
A hamburger machine presses loose mince into patties of a fixed diameter and weight, usually interleaved with greaseproof paper discs so the stack can go straight into the fridge or freezer without fusing. The mince is loaded into a mould, compressed by a lever or plate, and ejected as a finished patty.
The value is consistency, and it compounds in three directions. Cook times become predictable, so a burger that needs four minutes needs four minutes every time rather than three-and-a-bit for the thin ones and five for the thick. Food cost becomes controllable, because a 150g patty specification actually produces 150g patties rather than an average of 150g with a long tail of 175g ones you gave away. And prep becomes a batch task done in quiet periods rather than a job squeezed into service — a press lets one person form several hundred patties in an hour, stack them, and refrigerate them ready for the rush.
What patty size should you choose?
UK machines are commonly sold with 100mm and 130mm moulds, and the right choice follows from your bun, not the other way round.
- 100mm — suits a standard brioche bun and smash-style burgers, and it is the most common specification for UK burger bars. The 100mm table-top round burger press covers this.
- 130mm — suits larger sourdough or seeded buns and pub-style burgers where the patty is the centrepiece.
Match the mould to the bun you have already chosen. A patty should sit very slightly proud of the bun edge once cooked, because meat shrinks by roughly 10–20% in diameter on the grill depending on fat content and cooking temperature. A patty that exactly matches the bun raw will look mean once cooked, and one sized to a bun you later change becomes an expensive mistake — mould sets are not always interchangeable between machines, so check before you buy if your menu is likely to evolve.
How much does a burger patty weigh from a commercial press?
Weight is a function of diameter and thickness, and the arithmetic is worth doing before you set a menu price. On a 100mm mould, a 15mm patty is roughly 110–120g and a 20mm patty about 150–160g. On a 130mm mould, the same thicknesses give roughly 180g and 240g respectively.
| Mould | Thickness | Approx. weight | Typical use |
|---|---|---|---|
| 100mm | 10mm | 75–85g | Smash burgers, doubles, kids' menu |
| 100mm | 15mm | 110–120g | Standard single burger |
| 100mm | 20mm | 150–160g | Premium single, brioche bun |
| 130mm | 15mm | 180–190g | Pub-style burger |
| 130mm | 20mm | 235–245g | Large sourdough burger |
Always verify on scales with your own mince rather than trusting the table, because fat content and grind coarseness change density noticeably — a 20% fat coarse grind is measurably less dense than a lean fine grind at the same volume. Weigh twenty patties, take the average, and set your specification from that. It is fifteen minutes of work that fixes your gross margin for the year.
What mince is best for a burger press?
A press works best with coarse-ground chuck at roughly 20% fat. That ratio is not a matter of taste alone: too lean, at 10% or below, and the patty crumbles on the grill and eats dry, because there is not enough rendering fat to bind and baste it. Too fine a grind and the texture turns pasty under compression, producing something closer to a meatloaf than a burger.
Temperature is the detail that separates a good press operation from a frustrating one. Keep the mince below 4°C, ideally around 2°C, and take it out of the fridge in small batches. Warm fat smears rather than breaking cleanly, so it sticks to the mould, clogs the ejector, and produces a dense, greasy patty with a compacted surface that will not brown properly. If patties start sticking mid-batch, the answer is almost always that the meat has warmed up, not that the machine needs adjusting.
Use the press with a light touch. Over-compressing drives out air and produces a tight, tough patty; the aim is a patty that just holds together. Many kitchens find a light thumb dimple in the centre after pressing helps the burger stay flat rather than doming on the grill.
UK food safety for minced meat and burgers
Minced meat carries a specific and well-understood risk. Bacteria that sit only on the surface of a whole cut are distributed throughout the meat by mincing, which is why a rare steak is acceptable and a rare burger is not, absent controls. UK guidance requires burgers to reach 75°C at the core, or an equivalent such as 70°C held for two minutes, unless you operate a documented process agreed with your environmental health officer for serving burgers less than thoroughly cooked.
That process is real but demanding: it requires verified supply chain controls, specified sourcing and mincing arrangements, strict temperature control, and documented staff training, and it must be discussed with your local authority in advance. It is not something to adopt because a customer asked for medium-rare.
The everyday controls around a burger press are the familiar HACCP ones. Raw mince is handled on dedicated boards and surfaces, kept below 4°C throughout prep, and returned to refrigeration promptly — the press should not sit loaded with meat through a service. Formed patties held chilled must be at 8°C or below, and 2–4°C is the practical target; frozen patties at –18°C or below. Label with a date and operate strict rotation. Clean and sanitise the machine, moulds, and ejector between batches and at the end of every session, and record it.
Manual or automatic — and how much does it cost?
Table-top manual burger presses cost £160–£280 depending on mould size and build quality, and heavier commercial presses £250–£450. A solid manual press such as the commercial hamburger machine or the compact PH-130 burger press is the correct purchase for the overwhelming majority of independent UK sites.
Semi-automatic and hopper-fed patty formers start around £1,500 and rise steeply into production territory. The threshold is roughly this: a manual press forms perhaps 200–400 patties an hour with one operator, which covers a site selling a few hundred burgers a day comfortably if you batch in quiet periods. Only when you are consistently forming over a thousand patties a day, or supplying multiple sites from one kitchen, does an automatic former earn its cost.
There is no meaningful running cost on a manual press — no power, no consumables beyond paper discs, which cost a few pounds per thousand. Budget for a spare set of paper discs and check that replacement moulds and ejector plates are available for the model you choose. A press is a simple mechanical device that should last a decade; the thing that retires one early is an unavailable £30 part.
Frequently asked questions
What does a hamburger machine do?
A hamburger machine presses loose mince into patties of a fixed diameter and weight, usually interleaved with paper discs ready for the fridge or freezer. Hand-formed patties vary in weight and thickness, which means inconsistent cook times, unpredictable food cost, and complaints. A press sets one weight and holds it all day.
What patty size should I choose?
UK machines are commonly sold with 100mm and 130mm moulds. A 100mm patty suits a standard brioche bun and smash-style burgers, while 130mm suits larger sourdough or seeded buns and pub-style burgers. Match the mould to the bun you have already chosen — patties should sit slightly proud of the bun edge once cooked and shrunk.
How much does a burger patty weigh from a commercial press?
Weight is a function of diameter and thickness. On a 100mm mould, a 15mm patty is roughly 110–120g and a 20mm patty about 150–160g; on a 130mm mould the same thicknesses give roughly 180g and 240g.
