How Schools and Institutions Can Serve Safe Milk Every Day
Pictured: 200 Liters Milk Pasteuriser and 300 LTRS MILK CHILLER.
Quick answer: Schools either buy pasteurized milk from a licensed supplier or buy raw milk from farmers and pasteurize on site. Either way, milk must be kept cold until it is served, and equipment must be cleaned daily. A school with its own dairy herd can pasteurize with a batch pasteurizer and store in a milk chiller (from KSh 280,000 on H-TECH’s listings).
Key facts
  • Buy pasteurized or pasteurize on site

Two Ways to Supply Milk

OptionGood forNeeds
Buy pasteurized milkSchools without cattleLicensed supplier, cold storage
Pasteurize on siteSchools with a herd or nearby farmersPasteurizer, chiller, trained staff, KDB guidance

Equipment for On-Site Processing

Current listed prices incl. VAT (updated 11 October 2026).

How pasteurizing works: time and temperature. Chiller sizes: what size cooling tank.

How Much Milk Do You Need?

Multiply learners by the serving size and days. For example, 600 learners × 250 ml = 150 litres per day. A 200 L pasteurizer and a 300 L chiller give room for spills and staff use.

Hygiene Rules

Selling Surplus

Schools with their own herds sometimes sell surplus pasteurized milk to staff and the community through a milk ATM (milk ATM business). Check licensing first.

Also Safe Water

Schools also need treated drinking water: water treatment for schools and hospitals.
