Milk Chiller or Milk ATM First? How Farmers, Groups and Traders Should Decide
Pictured: 500L MILK CHILLER and 150 Liters Milk vending machine (portable).
Quick answer: Buy a milk chiller first if your problem is keeping milk fresh between milking and collection (farmers and groups selling to processors). Buy a milk ATM first if your opportunity is selling milk directly to consumers at retail prices (traders, shops and groups near towns). Many groups start with a chiller to protect quality, then add a milk ATM in town to capture retail margin. Chillers start from KSh 280,000 and milk ATMs from KSh 95,000.
Key facts
  • Chiller: protect quality
  • ATM: retail margin
  • Groups: chiller, then ATM
  • Traders: ATM first

Growing From One to Both

  1. Stabilise quality with a chiller and testing (see lactometer testing).
  2. Track how much milk you sell to processors and at what price.
  3. Open one milk ATM outlet and compare the margin per litre.
  4. Add a pasteuriser if selling fresh milk directly (see pasteurisers).

Size the tank with what size milk cooling tank do I need and plan with the collection centre calculator.

Frequently asked questions

What is the difference between a milk chiller and a milk ATM?

A chiller cools and stores bulk milk; a milk ATM keeps milk cold and dispenses it to customers.

Should a dairy group buy a chiller or an ATM?

Usually a chiller first to protect quality, then an ATM outlet for retail sales.

Can a milk ATM replace a chiller?

Not for bulk collection; ATMs hold smaller volumes for retail.

Do I need a pasteuriser with a milk ATM?

Milk sold fresh to consumers should be pasteurised.

Which earns more?

Retail through an ATM earns more per litre; a chiller protects volume and quality for bulk sales.
