The contact clamshell is the tool that changes the rhythm of a meat post: instead of searing one side, turning by hand, watching the other side, you place the piece between the two plates and the heat works both surfaces at once under controlled pressure. The result — cooking time cut by about 50%, even searing on both sides, a juicier result than open cooking — is not a marketing argument, it is physics: the pressure keeps the juices inside while the surfaces caramelise. The Single Stainless Clamshell is the single-phase 230V version of this professional tool — the entry into stainless contact grilling with no specific electrical installation constraint.
Contact grill vs griddle: what it changes operationally
The question comes up often in snack and fast food: griddle or clamshell? The two do not do the same job.
- x2 throughput at equivalent post: with a griddle, each piece occupies the surface for the whole cooking time (one side + the other). With the clamshell, the same surface cooks twice as fast — because both sides cook at once. In a 60-80 cover burger service, the griddle can become a bottleneck. The clamshell does not.
- Pressure = fat extraction: the 10mm-thick chrome upper plate pressurises the surface of the piece. Fat is extracted evenly over the whole contact surface, not just one side. Result: less greasy piece, crisper surface, neater presentation.
- Consistency with no monitoring: the 3 programmable cooking memories store a cooking time per type of piece. The operator loads, presses the matching key, the clamshell handles the rest and opens automatically at end of cycle. The cook is identical at every service, whoever the operator on post.
- The griddle stays complementary: for vegetables, eggs, garnishes — everything cooked in view and by hand — the open griddle is more suitable. In a complete snack, both have their place: griddle for sides, clamshell for proteins.
For which establishment is the Single Clamshell recommended?
- Start-up burger snack and fast food: at €2,290 excl. VAT on single-phase 230V, the Single Clamshell is the entry into professional contact grilling with no extra electrical investment. It suits a restaurant serving 60 to 100 covers/day on the meat post.
- Premises with a standard electrical installation: the 230V version installs on a standard 16A kitchen socket — no three-phase, no specialist electrician for commissioning. For rented restaurants that cannot modify the electrical installation, it is the decisive criterion.
- Kitchen with a compact worktop: at 330mm wide, the Single Clamshell fits in a small space. It is the format suited to dark kitchens, street snacks and linear kitchens where space is counted to the centimetre.
- Fast food: burger patty, chicken, fish burger: everything pressed and seared on both sides — burger, breaded chicken, fish fillet, hot sandwich — is in the clamshell's area of excellence. For restaurants with these products on the menu, it is the tool that structures the hot post.

What restaurateurs ask
- How to program the 3 cooking memories of the clamshell?
- The 3 memories let you store 3 distinct profiles — for example, key 1 = 120g burger patty, key 2 = chicken breast, key 3 = fish burger. Once programmed, the recipes are reproducible with no manual setting. The operator selects the number, places the piece, the clamshell handles the cycle and opens on its own.
- Does the clamshell work well for chicken or only for beef?
- The clamshell is particularly effective for thick pieces to cook on both sides: burger patty, chicken breast, escalope, fish fillet, hot sandwich. For chicken, cooking under pressure retains the juices and avoids drying out — a juicier result than open griddle, especially on whole fillets.
- Is the Single Clamshell 230V enough to open a burger snack?
- Yes, for a start-up or service up to 100 covers/day on the meat post. If your project plans a fast ramp-up (high-throughput opening from the first month), the Double Clamshell 400V is the right initial investment to avoid being limited from launch.
