Refrigeration for school and college canteens
School and college canteens serve hundreds of students in short, intense bursts — the lunch break, the period between lectures — and then go quiet. Menus are simple: sandwiches, samosas, idli, poha, Maggi, rolls, flavoured milk, buttermilk, cold coffee and shakes in colleges. Budgets are tight, staff are often few, and the canteen may close completely for vacations. Many schools and parents also expect healthier options such as milk, fruit and fresh food rather than fried snacks and fizzy drinks. Refrigeration needs to be simple to run, safe for children's food, robust enough for rush-hour crowds at the counter, and manageable through long holidays.
What the equipment has to cope with
- Demand comes in short bursts, with crowds of students at the counter during breaks and almost nothing in between.
- Budgets are limited, so equipment has to be economical to buy and run, and easy for a small team to maintain.
- Milk, curd, paneer and sandwiches are highly perishable, and children are more vulnerable to food-borne illness.
- Canteens often close for summer and winter vacations, leaving equipment idle for weeks.
- Canteen kitchens may be small, poorly ventilated rooms with frequent power cuts in some regions.
Typical temperatures
| Milk, flavoured milk and buttermilk | +1 to +4 °C |

| Paneer, curd and cheese | +2 to +5 °C |
| Sandwiches and packed salads | +2 to +5 °C |
| Chutneys and idli-dosa batter | +2 to +5 °C |
| Bottled water and juices | +3 to +8 °C |
| Ice cream and frozen snacks | −18 °C or colder |
Equipment
What to buy, and why.
A typical canteen has an upright reach-in in the kitchen for milk, paneer, curd, chutneys, batter and vegetables, and a glass-door cooler at the counter for flavoured milk, buttermilk, water and packed sandwiches so students can see what is available and staff can serve quickly. A chest freezer holds ice cream, frozen peas and frozen snacks. College canteens that serve cold coffee and shakes add an undercounter refrigerator at the drinks counter for milk and ice cream base.

Questions
- What should a canteen do with refrigerators during school vacations?
- Empty them, discard anything perishable, clean and dry the interiors, and either switch them off with doors propped open to prevent mould, or keep one unit running for non-perishable stock if needed. Before reopening, switch units on a day early and check they reach temperature before restocking.
- Can a canteen keep packed sandwiches in a drinks cooler?
- Yes, if the cooler is set for food rather than drinks. Sandwiches, curd and paneer need to stay at or below about +5 °C. Put food on the coldest shelves and check them with a probe thermometer. Discard sandwiches at the end of the day if they have been out of the cooler.
- How can a canteen keep milk cold during the lunch rush?
- Keep milk in a glass-door cooler or undercounter unit at the counter, not on the counter in crates. Load it cold before the break so the cooler only holds temperature, and restock from the kitchen reach-in after the rush.
