Hood-Type Dishwashers

Hood-Type Dishwashers — a hood-type dishwasher is one of the most important pieces of equipment in a restaurant kitchen; it ensures a dishwashing rhythm that matches the speed of service and hygiene standards; the right choice of hood-type dishwasher directly impacts kitchen efficiency and customer satisfaction.

How a hood-type dishwasher works

Hood-Type Dishwashers — the operating principle of hood-type dishwashers is simple and effective. Dish loading — staff place dirty dishes on a standardised loading rack (usually 50x50 cm); the rack is pushed into the machine or the dishes are placed on an internal tray. Hood lowering — using a handle or pedal, the hood lowers and hermetically seals the washing chamber; this prevents water splashes. Washing cycle — 60–120 seconds of intensive hot water and detergent spraying; temperature 55–65°C for washing and 80–90°C for final rinsing; see Glasswashers. Result — after the cycle, dishes are not only clean but also disinfected due to the high-temperature rinse; dishes are ready for immediate use.

Hood-type vs under-counter dishwasher — when to choose a hood-type

Hood-Type Dishwashers — the choice between a hood-type and an under-counter dishwasher is mainly based on dish volume and available space in the kitchen. Dish throughput — under-counter dishwasher: 20–40 racks per hour; hood-type dishwasher: 40–120 racks per hour; a large restaurant kitchen with more than 80 guests per day requires a hood-type dishwasher. Dish sizes — a hood-type dishwasher accommodates large pots, baking trays and restaurant plates that do not fit in an under-counter dishwasher; see Pot Washers. Kitchen efficiency — a hood-type dishwasher allows one operator to process more dishes; an under-counter model requires less active supervision but has lower capacity. Installation space — a hood-type dishwasher requires more floor space; an under-counter model fits in a standard kitchen cabinet space.

Hygiene and HACCP in a hood-type dishwasher

Hood-Type Dishwashers — professional hood-type dishwashers are designed to meet HACCP requirements. Rinsing temperature — in the final rinsing phase, the water temperature reaches +82°C–+90°C; this temperature ensures bacterial disinfection without chemical disinfectants; complies with European hygiene standards. Detergent dosing — professional hood-type dishwashers are connected to an automatic detergent and rinse aid dosing system; the correct amount of detergent ensures results and saves reagents; see Professional Dishwashers. Regular maintenance — daily cleaning: removing food residues from the filter; weekly: disinfection and limescale prevention; every 3–6 months: full technical maintenance. Documentation — the HACCP protocol requires documentation of dishwashing temperatures; most modern hood-type dishwashers have a data logger.

Operating costs of hood-type dishwashers

Hood-Type Dishwashers — the daily operating costs of hood-type dishwashers are significant but optimal with the right choice and maintenance. Water consumption — an average hood-type dishwasher uses 2–4 litres of water per cycle; 300 cycles per day = 600–1200 litres; a water softener is essential to prevent limescale build-up and extend service life. Energy consumption — a hood-type dishwasher requires 3–11 kW of electricity; higher consumption than an under-counter model; energy-efficient models save costs in the long term; see Glasswashers. Detergents — professional detergent and drying agent; automatic dosing ensures economical consumption; BHS can recommend suitable reagents. Maintenance costs — regular maintenance significantly reduces repair costs; a worn filter or scaled heater increases energy consumption.
