Kitchen extraction cleaning - open kitchens
In an open-plan or theatre kitchen, the cooking - and the extraction canopy above it - is on show to the diners. That puts the extraction on display in two senses: it must look clean (a greasy canopy over the food is a bad look), and it must work well (capturing the cooking so smoke and smells don't reach the dining room). Here is what extraction in view means for open kitchens. This is general commentary on open-kitchen extraction.
The short answer
Open-plan and theatre kitchens - where the cooking is visible to the diners, part of the experience - have become popular. But putting the kitchen on show puts the extraction on show too, and creates specific demands. Here's what extraction in view means. This is general commentary. Extraction on display, two ways. In an open or theatre kitchen, the extraction canopy sits above the cooking, in full view of the diners. This puts it 'on display' in two senses, both of which matter: how it looks (the diners see it), and how well it works (with no wall to contain the cooking, its capture directly affects the dining room). Both have to be right. It must look clean. The canopy is a visible feature right above the food being cooked and served - so its appearance matters to the diners. A greasy, grimy, discoloured canopy is an unappetising sight: it looks unhygienic (grease over the food), undermines the impression of a clean kitchen, and detracts from the dining experience and the venue's image. Diners notice a dirty canopy, and it reflects badly. So in an open kitchen, the canopy must look clean - visibly well-kept - which means keeping it clean (and in good condition). It must work well. Just as important, the extraction must capture the cooking effectively - because in an open kitchen there's no wall between the cooking and the dining room. In a closed kitchen, even if some smoke or smell escapes the canopy, the kitchen walls contain it; in an open kitchen, anything the extraction fails to capture escapes straight into the dining room - smoke, cooking smells, heat - spoiling the diners' experience (a smoky, smelly dining room). So effective capture (the canopy capturing the plume, the system pulling full airflow) is especially important in an open kitchen: it's what keeps the cooking's output from reaching the diners. Cleaning serves both. Keeping the extraction clean serves both demands. The look: a clean canopy looks right on show (well-kept, hygienic-looking). The function: a clean, well-working system pulls its full airflow, so it captures the cooking effectively (keeping smoke and smells out of the dining room). Conversely, a grease-choked extraction fails both: it looks bad (a greasy canopy on show) and captures poorly (reduced airflow letting smoke and smells escape into the dining room). So keeping it clean is doubly important in an open kitchen - for the look and the function - on top of the fire safety any kitchen needs. So open-kitchen extraction is in view, and must satisfy both the eye and the function - keep it clean and well-maintained so it looks right and captures the cooking, keeping the dining room clear. So extraction in view must look clean and work well. This is general commentary on open-kitchen extraction.
Key points
Extraction on show
In an open-plan or theatre kitchen, the extraction is on show - the canopy is effectively part of the dining room, visible to the diners. Open and theatre kitchens make the cooking part of the experience: the diners can see the chefs at work, the flames, the plating. But with the cooking on view, so is the extraction canopy above it - a large, prominent feature right over the cooking, in full sight of the diners. So the canopy is no longer a hidden piece of kitchen equipment; it's a visible part of the dining environment.
This 'on show' status matters in two ways, both of which the extraction must satisfy. How it looks: the diners see the canopy, so its appearance is part of the dining room's look. How it works: with the kitchen open to the dining room, the extraction's capture directly affects the diners (no wall contains the cooking). So putting the kitchen on show puts the extraction on show - and creates demands on both its appearance and its function. Both have to be right, as the next sections cover. So extraction on show - the canopy is part of the dining room - is the situation an open kitchen creates. The look and the function both matter. So the canopy is a visible part of the dining room. This is general commentary.
It must look clean
The first demand of an open kitchen is that the canopy must look clean - because a greasy, grimy canopy on show over the food is an unappetising, off-putting sight. The canopy is a visible feature right above the food being cooked and served, in the diners' view - so its appearance is part of what the diners see and judge. A canopy that's greasy, grimy, discoloured or dripping is an unappetising sight: it looks unhygienic (visible grease over the food), it undermines the impression of a clean, well-run kitchen, and it detracts from the dining experience and the venue's image.
Diners do notice a dirty canopy - it's a prominent thing right over the cooking - and it reflects badly on the establishment (suggesting poor hygiene and care). So in an open kitchen, the canopy's appearance is a real concern for the dining experience and the venue's reputation - it must look clean, well-kept and hygienic. This means keeping it clean (and in good condition - not corroded, damaged or grease-stained). So it must look clean - a greasy canopy over the food looks bad - is the aesthetic demand of an open kitchen, on top of the functional and fire-safety reasons any kitchen has to keep its canopy clean. The appearance is a business concern here, not just a hygiene one. So the canopy must look clean on show. This is general commentary.
It must work well
The second, and arguably more important, demand is that the extraction must work well - capturing the cooking effectively - because in an open kitchen there's no wall to contain what escapes. In a closed kitchen, even if some smoke or smell escapes the canopy's capture, the kitchen's walls and doors contain it (it stays in the kitchen). But in an open-plan or theatre kitchen, the kitchen is open to the dining room - so anything the extraction fails to capture escapes straight into the dining room: smoke, cooking smells, heat, and grease-laden vapour all reach the diners.
So effective capture is especially important in an open kitchen: the extraction must capture the cooking's plume effectively at the canopy (with good capture - proper canopy positioning and full airflow) so it's drawn away rather than escaping. If it doesn't - if the capture is poor or the airflow weak - the smoke and smells spill into the dining room, giving the diners a smoky, smelly experience (unpleasant, and reflecting badly on the venue). So the functional performance of the extraction directly affects the diners in an open kitchen, in a way it doesn't in a closed one. This makes keeping the extraction working well (capturing effectively, pulling full airflow) crucial for the open kitchen - it's what keeps the cooking's output from reaching the diners. So it must work well - no wall to contain the cooking - is the functional demand, making effective capture essential. So effective capture keeps the cooking from the diners. This is general commentary.
Cleaning serves both
Keeping the extraction clean serves both demands of the open kitchen - the look and the function - because a clean system both looks right and works well. The look: a clean canopy looks right on show - well-kept, hygienic, not greasy or grimy - satisfying the appearance demand. Regular cleaning (of the visible canopy especially) keeps it looking clean for the diners. The function: a clean, well-working system pulls its full airflow, so it captures the cooking effectively (drawing the plume away at the canopy, keeping smoke and smells out of the dining room). A grease-choked system, by contrast, has reduced airflow and captures poorly - letting the cooking's output escape into the dining room.
So a grease-choked extraction fails both demands at once: it looks bad (a greasy canopy on show) and captures poorly (letting smoke and smells reach the diners). And a clean one satisfies both: it looks clean and captures well. So keeping the extraction clean and well-maintained is doubly important in an open kitchen - it's what delivers both the visible cleanliness the diners see and the effective capture that keeps the cooking from reaching them. (On top of this, of course, the extraction still needs cleaning for the fire safety any kitchen requires - so the open-kitchen demands add to, not replace, that.) So cleaning serves both - clean looks right and captures well - which is why an open kitchen has extra reason to keep its extraction clean. So keeping it clean serves the look and the function. This is general commentary.
Keep it clean, on show
So in an open-plan or theatre kitchen, the extraction is in view - and keeping it clean and well-maintained matters for the look (the visible cleanliness the diners see), the function (the effective capture that keeps smoke and smells out of the dining room), and the safety (the fire-risk control any kitchen needs). All three are served by keeping the extraction clean. So keep it clean, on show - for the look, the function and the safety.
The practical upshot is that an open kitchen has extra reason to keep its extraction clean and well-maintained, above and beyond a closed kitchen: the diners see the canopy (so it must look clean) and are directly affected by the capture (so it must work well), as well as the fire safety that applies everywhere. So the open kitchen should keep its canopy visibly clean and well-kept (regular cleaning of the visible parts for the look), and keep the whole system clean and working (for the capture and the fire safety) - the visible cleanliness and the hidden performance both mattering. A neglected extraction in an open kitchen shows twice over - a greasy canopy the diners see, and smoke and smells reaching them - as well as the hidden fire risk. So keep the open kitchen's extraction clean, on show: for how it looks, how it works, and how safe it is. So keep it clean for the look, the function and the safety. This is general commentary on open-kitchen extraction.
Questions
Because the canopy is on show to diners (so it must look clean) and there's no wall to contain the cooking (so the extraction must capture it well, or smoke and smells reach the dining room). An open-plan or theatre kitchen puts the cooking and the extraction canopy in view of the diners, which creates two demands. The canopy must look clean - it's a prominent feature right above the food, so a greasy, grimy canopy is an unappetising, off-putting sight that undermines the dining experience and the impression of hygiene. And the extraction must work well - with the kitchen open to the dining room, there's no wall to contain the cooking, so anything the extraction fails to capture (smoke, smells, heat) escapes straight into the dining room, spoiling the diners' experience. So the extraction's appearance and performance both directly affect the diners in an open kitchen. Keeping it clean serves both (and the fire safety). So it matters more because it's seen and its capture affects the diners. So because it's on show and affects the diners. This is general commentary.
The smoke, cooking smells and heat escape into the dining room (there's no wall to contain them), spoiling the diners' experience with a smoky, smelly dining room. In a closed kitchen, the walls contain any cooking output that escapes the canopy's capture. But in an open kitchen, the kitchen is open to the dining room, so anything the extraction fails to capture escapes straight into the dining area: smoke, cooking smells, heat and grease-laden vapour reach the diners. So if the extraction captures poorly (from a badly-positioned canopy, or reduced airflow in a grease-choked system), the dining room becomes smoky and smelly - an unpleasant experience for the diners, and one that reflects badly on the venue. This is why effective capture (a well-positioned canopy, full airflow from a clean system) is especially important in an open kitchen - it's what keeps the cooking's output from reaching the diners. So poor capture lets smoke and smells into the dining room. So it spoils the diners' experience. This is general commentary.
Yes - a greasy, grimy canopy on show over the food looks unhygienic and off-putting, undermining the dining experience and the impression of a clean kitchen; diners notice it and it reflects badly. In an open kitchen, the canopy is a prominent, visible feature right above the food being cooked and served - so its appearance is part of what the diners see and judge. A greasy, grimy, discoloured or dripping canopy is an unappetising sight: it looks unhygienic (visible grease over the food), suggests a poorly-kept kitchen, and detracts from the dining experience and the venue's image. Diners do notice a dirty canopy (it's hard to miss, right over the cooking), and it reflects badly on the establishment. So a dirty canopy genuinely puts diners off and harms the venue's impression - which is why keeping the canopy visibly clean matters in an open kitchen (for the business, on top of hygiene and fire safety). So yes - a dirty canopy on show puts diners off. So yes - it looks unhygienic and off-putting. This is general commentary.
Keep the visible canopy regularly cleaned and in good condition (not greasy, stained, corroded or damaged), alongside the whole-system cleaning for capture and fire safety - the look needs frequent attention as it's on show. In an open kitchen, the visible canopy needs regular cleaning to keep it looking clean for the diners - wiping and cleaning the visible surfaces frequently (as it's on show, grease and grime show quickly), and keeping it in good condition (not corroded, damaged or permanently stained - which may mean maintenance or refurbishment, since appearance matters). This visible upkeep is on top of the whole-system cleaning (canopy interior, filters, ductwork, fan) needed for effective capture and fire safety. So keeping an open-kitchen canopy looking clean means frequent attention to the visible surfaces (for the look) plus the regular whole-system cleaning (for the function and safety). The look demands more frequent visible cleaning than a hidden canopy would. So keep the visible canopy regularly cleaned and well-kept, plus the whole-system cleaning. So clean the visible canopy often, and the whole system. This is general commentary.
Yes - the visible canopy looking clean isn't enough; the whole system (canopy interior, ductwork, fan) still accumulates grease and needs cleaning for capture performance and fire safety, as in any kitchen. Keeping the visible canopy looking clean (for the diners) is necessary in an open kitchen, but it's not sufficient. The whole extraction system - the canopy interior, the ductwork, the fan - still accumulates grease (hidden from the diners) just as in any kitchen, and still needs whole-system cleaning: for the fire safety (the grease is fuel, especially in the hidden ductwork and fan), and for the capture performance (a grease-choked system has reduced airflow and captures poorly, letting smoke and smells into the dining room - which the diners would notice). So an open kitchen needs both: the visible canopy kept looking clean (for the look), and the whole system cleaned (for the function and fire safety). The visible cleanliness is on top of, not instead of, the whole-system cleaning. So yes - it still needs whole-system cleaning, beyond the visible canopy. So yes - the whole system, plus the visible look. This is general commentary.
It has the same functional and fire-safety requirements, but with added emphasis on effective capture (no wall to contain the cooking) and on appearance (the canopy on show) - so the design should ensure strong capture and an acceptable look. A theatre or open kitchen's extraction has the same fundamental requirements as any kitchen's (effective extraction of the cooking's heat, smoke and grease, and fire safety), but the open setting adds emphasis in two areas. Capture: with no wall to contain the cooking, the extraction must capture the plume effectively (a well-positioned, well-sized canopy and strong airflow), so nothing escapes into the dining room - so the capture design is especially important. Appearance: the canopy is on show, so its appearance (and that of the visible ductwork or extract features) matters to the dining room's design - it should look acceptable, even attractive, as well as function. So the design should ensure strong capture and an acceptable appearance, on top of the usual requirements. This is a design matter for a competent designer. So it needs strong capture and a good look designed in, plus the usual. So yes - extra emphasis on capture and appearance. This is general commentary; design is for a competent designer.
In an open kitchen the canopy is on show and the capture affects the diners. We keep the whole system clean to TR19 Grease - so the canopy looks clean, the extraction captures the cooking effectively, and the fire risk is controlled.
