Supplying steam to a milk kettle — customer facility
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.
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.
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.
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.
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.
