Tray service in hospitals

In centralised tray service, each patient's tray is assembled in the main kitchen on a tray line, checked against the diet card (name, ward, bed, diet), and carried to wards in heated or insulated trolleys. It gives the best control of diet and portions. In decentralised service, food goes in bulk to ward pantries, where it is reheated if needed and plated; food is hotter, but control is harder and more staff and equipment are needed on each ward.

Buffet vs cafeteria

BuffetFood displayed on tables, usually at a fixed price per head; guests serve themselves or are helped by staff; used for functions; seated or standing; wide choice; more waste.
CafeteriaFood on a counter; guests queue with trays and pay for each item chosen at the cash point; used daily in canteens; quick turnover; easier portion control by counter staff.

Merits and limits of self-service

  • Merits: fewer staff, fast service for large numbers, lower prices, guests see the food before choosing.
  • Limits: less personal; queues at peak times; portion control harder at buffets; more waste.
  • Hygiene: sneeze guards, a separate serving spoon for each dish, small quantities displayed and refilled, hot food above 60°C and cold food at 5°C or below.
In food service

In a hospital, centralised tray service lets the diet kitchen assemble each patient's tray to the diet order on a tray line, while an industrial canteen uses cafeteria or free-flow counters to feed hundreds of workers in a short lunch break.

Remember it

Who moves? Table: staff bring food to seated guests. Assisted: half and half. Self: guests go to the food. Single-point: one counter to order, pay and collect. Specialised: food goes to where the guest is.
