To determine what size of pasteurizer to buy for your operation, simply make an estimate of the number of calves to be fed and what volume of milk you would provide at each feeding.

For instance: If you have a 400 cow dairy and feed all of your calves 2.5 quarts for 7 weeks, then you would need a system for 55 calves or 34 gallons of milk. The DT37 would meet your needs and provide you room for future expansion.

If this same dairy only fed its heifers, then the DT-Platinum would be the correct choice. Below is a chart to help you find the right size DT series pasteurizer for your specific needs.

Pasteurization Procedure

Pasteurizing with the Dairy Tech system couldn't be made any easier. Simply fill the pasteurizer drum with milk by having it pumped directly in while milking, or fill it with buckets. Replace the lid and push the START button on the control board. Now go back to the other important tasks on the dairy and allow the automated cycle to go to work.

The heater will come on by itself as the propeller begins to circulate the milk for even heating. The thermocouple monitors the temperature of the milk until it reaches that required for pasteurization. Colostrum heated to 140°F (60°C) and held for 60 minutes, milk heated to 145F (63°C) and held for 30 minutes. Our equipment is easily adjusted to accommodate both time/temperature combinations. However, at the factory we set the equipment to the lower temperature to protect the immunoglobulin in the colostrum, and for more energy efficient heating.

Once the timing of the heat cycle is complete, the system automatically shuts down the heat and sends cold water through to cool the milk. The propeller continues to mix the milk for efficient cooling. At the end of the cycle, the equipment sounds an alarm and shuts down. The milk can now be fed to the calves at normal body temperature, or it can be cooled further to be fed later.

Installation of the System

The equipment is fully assembled and tested at the factory. Everything needed to pasteurize is included. Both DT Platinum and DT Series require professionally wired 220vac 40amp service for the heaters and a 120vac ground fault plug. Simply plug in and attach the provided cold water hose to the supply bib. It Couldn’t be any easier!

It is recommended that a hot water supply is also located nearby for cleaning purposes. Some dairy inspectors allow placement of the system in the milk house or tank room, but always check with your inspector to be sure you meet local restrictions.

Cleaning of the System

APPROPRIATE DISINFECTANTS - WATER - and a LITTLE ELBOW GREASE!

Dairy Tech has designed their pasteurizers with 3 goals in mind: Affordable, Simple to Operate, and Easily Repaired. As part of our effort to make operation of these units as user friendly as possible, we also concentrated on the cleaning process. Milk does not have to flow through plates or heat exchangers, and therefore; extensive rinsing, washing with acids and flushing are not part of the cleaning. In fact, the only surfaces exposed to milk are the inside of the drum, stainless heating coils, and the propeller used to circulate the milk. Clean the exposed surfaces as you would any other calf feeding equipment. For 90% of the cleanup, appropriate disinfectants and hot water are all that is required. DT Platinum units have made clean-up even easier. Use the included scrub brush to clean out the milk pot!
