Steam Generator for Milk, Ayran and Dairy Product Production

When milk is heated directly over fire, it sticks to the bottom and the batch is lost. With indirect heating by steam, the milk does not contact the heat source; temperature remains stable during pasteurization, ayran, yogurt and cheese production. Sized for dairies and medium-sized businesses.

Why is milk sticking to the bottom so critical?

When milk is heated directly by fire or resistance heaters, the bottom of the kettle overheats and milk sticks to the bottom. The burnt taste and smell spread throughout the batch; the product in that kettle often becomes unsellable. For a small business, this means losing a day's production. With indirect heating by steam, the product never contacts the heat source, heat passes evenly through the bottom and side surfaces of the kettle, so no hot spots form. We explain the method details on our "Cooking with steam" page.

Where is steam used in a milk processing facility?

Thermal processing and pasteurization: milk must be held at a certain temperature for a certain time; since steam temperature is determined by pressure, this temperature can be maintained steadily. Ayran production: the stage where yogurt is diluted and heat treated requires the same control. Yogurt: heating and resting the milk before incubation. Cheese: bringing milk to the desired temperature before coagulation and holding it there. In products requiring long boiling like cream, the difference with indirect heating is most noticeable in color and consistency.

For dairies and medium-sized businesses

Most industrial steam boilers on the market are designed for large facilities, producing thousands of kilograms of steam per hour; this scale is for power generation and heavy industry. The needs of a dairy or medium-sized milk processing plant are far smaller. Our working range is up to 100 liters of steam per hour; with special manufacturing, up to 200 liters. The right solution at this scale is a compact steam generator that doesn't require a boiler room or continuous operator. The machine comes ready to connect, fully autonomous after water and electric connections; it takes its own water, maintains the set pressure automatically.

How is the system sized?

The correct capacity is determined according to your boiler volume and target process temperature; resistance heaters are selected accordingly. If you have an existing jacketed boiler, the system is planned to connect to it; if not, custom manufacturing is done according to your usage site. Every machine is tested and approved in our facility before shipment and comes with a 1-year warranty. Since 1996, over 300 steam generators have been operating in the field.

Frequently asked questions

How do I prevent milk sticking to the bottom?
The most common solution is switching from direct heating by flame or resistance to indirect heating by steam. Since milk does not contact the heat source and heat distributes over all surfaces of the kettle, no burning occurs at the bottom and taste and smell remain unaffected.
Does steam contact the milk?
No. Steam is supplied to the boiler jacket and does not contact the product; heat is transferred through the kettle surface. That's why the method is called "indirect heating".
What capacity is needed for my dairy?
Capacity depends on your boiler volume and target temperature; there is no single standard answer. Our production range is up to 100 liters of steam per hour, up to 200 liters with special manufacturing. If you provide your daily processed milk quantity and boiler size, we determine the suitable model.
Can it connect to my existing jacketed boiler?
Yes, it can. The system is planned to supply steam to your existing boiler; for connection dimensions and placement, we take measurements and photos.
Do I need a steam generator or steam boiler?
For small and medium-sized milk businesses, a steam generator is usually sufficient: compact, quick to start, does not require a boiler room or continuous operator. We explain the difference in detail in our article "What is a steam generator and how does it differ from a steam boiler?".
