Turn Waste Milk
Into Value

Every milking session, litres of milk go down the drain. The AXIS disc-stack drying system converts your on-farm waste milk into shelf-stable, feed-grade powder, right where it is produced.

The Challenge

Milk That Never Reaches the Vat

New Zealand dairy farms generate an estimated 140 to 180 million litres of waste milk every season. Most of it goes straight to the effluent system. That is not just lost revenue; it is an environmental liability that is coming under increasing regulatory scrutiny.

Inline Milk Residue

After every milking, 45 to 200 litres of milk remains in the pipeline depending on your shed type. On water-purge farms, 100% of this goes to effluent, twice a day, every day of the season.

Up to 39,600 L/year on a herringbone shed

Antibiotic Treatment Milk

When a cow is treated with intramammary antibiotics, her milk cannot enter the bulk tank for the full withholding period. A typical 325-cow farm discards 2,500 to 6,000 litres of antibiotic milk every season.

Cannot enter the bulk tank under any circumstances

Colostrum Surplus

The first four to six milkings post-calving produce colostrum that cannot enter the bulk tank. Surplus colostrum is highly nutritious but perishable. A 325-cow farm generates 10,000 to 19,500 litres of surplus colostrum each season.

The Regulatory Pressure Is Growing

The National Policy Statement for Freshwater Management 2020 and the National Environmental Standards for Freshwater 2020 are tightening effluent discharge limits across New Zealand. Waste milk has a Biochemical Oxygen Demand of approximately 110,000 mg/L, compared to 200 to 400 mg/L for domestic sewage.

Converting waste milk to powder eliminates effluent discharge entirely and provides a clear, auditable compliance pathway for your Farm Environment Plan.

The AXIS System

A Complete On-Farm Milk Valorisation Platform

The AXIS disc-stack drying system is a portable, self-contained unit that sits beside your milking shed. It intercepts waste milk before it reaches the effluent system and converts it into a stable, feed-grade milk powder that you can use on-farm or sell.

AXIS System Portable. Scalable. On-Farm.

Complete Waste Stream Recovery

Handles inline residue, antibiotic milk, colostrum, and mastitis milk on a single, dedicated processing line. Your bulk tank is never compromised.

45% Less Energy Than Drum Dryers

SiC induction heating at 85°C versus 170°C for conventional drum dryers. Lower operating temperature means better product quality and lower power bills.

Feed-Grade Powder Output

The output is a shelf-stable, feed-grade milk powder suitable for calf feeding on the farm of origin. Nutritionally superior to commercial calf milk replacer.

Portable and Trailer-Mounted

Compact footprint from 1.2 m x 1.0 m. Can be shared between farms or relocated as your operation changes. No permanent infrastructure required.

Enzymatic Antibiotic Neutralisation

Integrated enzymatic pre-treatment degrades beta-lactam antibiotics to below detectable limits before drying, ensuring your powder meets feed-grade standards.

The Process

From Waste Milk to Powder in Four Steps

01

Collect

Waste milk is intercepted before the CIP flush and gravity-drained into a dedicated collection tank. Inline residue, antibiotic milk, and colostrum are all handled on a separate line from your bulk tank.

02

Pre-Treat

For antibiotic-containing milk, enzymatic pre-treatment using beta-lactamase degrades beta-lactam residues to below detectable limits. Colostrum and clean residue milk skip this step.

03

Dry

Milk is fed onto the heated rotating discs as an ultra-thin film of 0.12 mm. SiC induction heating at 85°C evaporates the water in 7.6 seconds. Operating temperature is half that of conventional drum dryers.

04

Collect Powder

Dried powder is scraped from the disc surface and collected in a food-grade container. The output is a shelf-stable, feed-grade milk powder ready for calf feeding or storage. Valued at NZD 8 to 12 per kilogram.

The Team

Built by People Who Know Dairy

DairyTech Solutions was founded by a team with deep roots in New Zealand dairy farming, engineering, and agribusiness. We are not a tech company that discovered agriculture. We are farmers and engineers who built a solution to a problem we have seen first-hand.

Dene Holyoake

Founder

The originator of on-farm milk drying in Northland, Dene developed the first roller drum dryer concept over a decade ago. Her approach has always been grounded in practical, common sense thinking -- if it does not work simply and reliably on-farm, it does not work at all. That philosophy remains at the heart of the AXIS system.
