The guide to 7 costly mistakes in a food laboratory
Designing or upgrading a food laboratory is no game. Every technical decision has a direct impact on food safety, productivity and operating costs. Yet many project owners discover too late that their initial "false good ideas" cost them dearly in maintenance, production stoppages or forced compliance upgrades.
At WeChefs, we meet caterers, pastry chefs, chocolatiers and restaurateurs every week who have faced these technical dilemmas. To make these choices more tangible, we offer you a spot-the-7-mistakes game.
Are you more tiles or resin? Air conditioning or industrial refrigeration? Let's see what changes…
1. Floors: tiles or resin?
The floor is the first sanitary barrier in a laboratory.
- Tiles: often chosen for their attractive purchase price and familiar look. But their joints are their Achilles' heel: they crack over time, accumulate bacteria and residues, and stand up poorly to high-pressure cleaning.
- Food-grade resin: a continuous, jointless, non-slip surface that resists chemicals. It lasts longer, is easier to clean and meets sanitary standards.
Winner: resin. A durable, hygienic choice adopted by modern laboratories.
2. Partitions: sandwich panels or Comacel boards?
Partitions must withstand impacts, humidity and repeated cleaning.
- Comacel: an inexpensive but fragile solution. Boards warp, get damaged at the joints and are hard to maintain over time.
- Insulated sandwich panels: specifically designed for food environments. Their smooth, washable surface meets standards, and their thermal insulation improves comfort in working areas.
Winner: sandwich panels. The professional solution, suited to health audits and high production rates.
3. Cold: air conditioning or industrial refrigeration unit?
Cold is at the heart of food performance.
- Air conditioning: designed for human comfort, it guarantees neither stable temperatures nor the humidity control some productions require (chocolate, fresh products). It consumes a lot and wears out quickly.
- Industrial refrigeration units (glycol water, centralised networks): designed to maintain precise, even and stable temperatures. Their robustness ensures 24/7 continuity of service, essential in an industrial approach.
Winner: industrial refrigeration. More expensive at first, but far more reliable and efficient in the long run.
4. Drainage: simple floor drain or stainless steel channel?
Hygiene also depends on water drainage.
- Simple floor drain: limited capacity, prone to blockages and creates areas of stagnant water.
- Stainless steel channel: designed for food-processing environments, it provides optimal drainage, easier cleaning and better safety during health audits.
Winner: stainless steel channel. More effective and safer, especially at high production rates.
5. Electricity: standard installation or smart sub-meters?
Energy is becoming a major cost item.
- Standard installation: a single consumption line, with no way of distinguishing uses or allocating costs between activities or occupants.
- Smart sub-meters: track consumption in real time by area, machine or tenant. The result: fair billing and energy optimisation.
Winner: sub-meters. An investment that pays for itself quickly, bringing transparency and control.
6. Ventilation: simple extraction hood or dedicated air handling?
Air quality affects safety as much as productivity.
- Simple hood: enough to extract cooking fumes, but limited in a complete laboratory where humidity, dust or odours build up.
- AHU (air handling unit) with filtration and humidity control: ensures full control of the air. Essential for sensitive productions (fine pastry, chocolate, fresh dishes).
Winner: industrial air handling. Better working comfort and lasting compliance.
7. Cleaning: home-made fixes or a standardised plan?
Cleaning is often seen as secondary, yet it determines compliance.
- Household products: widely used but unsuited to food industry requirements, with risks of chemical residues or non-compliance.
- HACCP cleaning plan + approved products: guarantees consistent hygiene, clear traceability and extends the life of surfaces and equipment.
Winner: standardised plan. A guarantee of safety and peace of mind during inspections.
Conclusion: the real cost is the cost of mistakes
Choosing tiles over resin, air conditioning over industrial refrigeration, a floor drain over a channel… Decisions that seem trivial at first, but translate into extra maintenance costs, productivity losses and non-compliance.
The moral of this "spot the mistakes" game? In a food laboratory, there are no small choices. Every detail counts.
At WeChefs, we chose to design laboratories where these choices are built in from the start:
- validated technical solutions,
- standards met,
- infrastructure ready to produce,
- modularity to support growth.
Our mission: to take you from project to production without wasting time or resources.
