TECHNOLOGICAL SCHEMES OF ENERGY SAVING SYSTEMS FOR MILK COOLING USING FREE COOLING AND LOW FREEZING POINT REFRIGERANTS

A. Korshunov, V. Ivanov

Farm animals milk is the valuable, but quickly spoiling foodstuff. Therefore it is necessary to make his cleaning and cooling for milk quality preservation.

The systems existing now and used on farmer farms for milk cooling are rather energy-intensive and ineffective. Therefore development and deployment of energy saving milk cooling systems is the perspective solution of this problem.

The particular interest represents energy saving systems for milk cooling using free cooling and low freezing point refrigerants which allow to solve problems in the milk preprocessing field.

In article the analysis of the developed milk cooling systems on farms using free cooling and low freezing point refrigerants on the example of 5 schemes is made, each of which has the advantages and shortcomings.

Perspective energy saving milk cooling systems using free cooling and low freezing point refrigerants for introduction in farms and other field of agriculture have to have a number of advantages before already existing systems:

– increased energy efficiency;

– minimum capital expenditure;

– minimum operational expenses;

– maximum automation level;

– design simplicity;

– small overall dimensions;

– small metal consumption;

Due to above-mentioned requirements for milk cooling systems of the most suitable from the submitted technological schemes the scheme of option 4 is necessary.

There are also other schemes versions for milk cooling systems using free cooling, for example, using ground waters which main shortcomings is existence similar sources need, an water excessive consumption, etc.
