Dairies

Dairies is the name for the industry that supplies milk and various derived products such as cheese. This is a very energy-intensive industry. In 2017, the size of the global dairy market was $ 415 billion, which is the equivalent of more than 200 million tons.

Milk is the predominant part. Cattle farming is a major contributor to greenhouse gas emissions, so dairies around the world can, with targeted efforts, significantly reduce some of the emissions from the processing of dairy products.

Heat Recovery from the Pasteurisation Process

In industrial dairies, all milk products are based on heat energy. The heat required, and thus the energy consumption, varies depending on the type of product. When implementing exodraft’s heat recovery technologies in dairy processes, each focus area is based on a prior analysis of the available heat energy.

In other words, heat recovery technology can be optionally implemented in all locations in the industry, from the initial processes of thermalisation, prolonged low-temperature pasteurisation of milk, short-term pasteurisation of milk and cream at high temperature, ultra-pasteurisation, and treatment and sterilization of containers at ultra-high temperatures. 

As there are several processes involved in the dairy industry’s production of various dairy products, heat input at specific temperatures at varying times is required. Some processes require rapid cooling. This allows heat to be recovered from the cooling process and used again in heating.

All heating processes can, using exodraft’s heat recovery technology, reduce energy consumption, with immediate readable savings directly on operation.

Heat Recovery from Boilers

Boilers are installed in dairies to supply heat through steam for all the processes that require heat supply. These boilers have a great potential for heat recovery.

Mechanical exhaust fan technology / chimney draught from exodraft can, through draught control, reduce fuel consumption, optimise operating conditions and cut the top off maintenance costs. Heat recovery can be applied to both combustion and process air. Depending on the type of boiler, the physical conditions and the installation paths, exodraft has technologies that can be used in every conceivable situation.

For example, heat recovered from flue gases can be stored in a buffer tank from which there can be freely drawn heat for use in the dairy process. The heat can, of course, also be used for cleaning, bathing water, heating of office premises, etc.

The recovered heat can also be used in absorption coolers, which in turn can be used in the dairy industry’s cooling processes. If more heat is recovered than can be used for your own needs, the excess heat can be sold to the local central heating plant.
