Principle requirements to cooling agents are discussed. Characteristics of various cooling agents are compared. Problems of the cooling agents applications in view of international documents defining requirements connected with environment protection are outlined.

In the dairy sector heat exchanging apparatus with different surface intensifiers are used for setting heat supplying process and technological treatment of a product. The article contains results of the experimental study carried out at the chair TMPU of the Moscow Energy Institute that compare efficiency of heat exchangers with surface intensifier and give necessary engineering calculations that can be used for choosing heat exchanging equipment.

Russian and international normative documentation is analyzed that include requirements to pumping equipment. The requirements refer to materials, surface treatment, welding, mild pumping conditions etc.

Among great variety of modern pumping equipment most severe requirements exist for pump units applied in food, parfume, pharmaceutical and microbiological industries. A number of standards related to this kind of equipment have been developed. Pumps should meet all these norms, and application of pumps without appropriate certificates is impossible.

Main reasons of low energy efficiency at boilers are given. Possibilities to improve energy efficiency of heat supplying system at one concrete dairy are outlined.

Application of microfiltration together with pasteurization is a further step in the field of high quality liquid milk technology development. This is milk with extended shelf life, and components that are usually destroyed at heat treatment are preserved. Microfiltrated milk has a usual taste of pasteurized milk, and together with above mentioned properties and price the product is attractive for selling. Microfiltration plants with ceramic membranes regular operate for more than 10 years, and membrane operation life exceeds 5 years. Experience of dairies operation abroad has shown that investments in microfiltration are justified.

Information is given about production of whole milk powder, dry cream and dry ice-cream mixtures as well as milk powder (replacing human milk) and powdered milk mixtures for babies, skim milk powder, whole milk replacers and whey powder. Production of canned milk products in 2008 is characterized.

This is the information about new line of milk fat replacers developed at the company Efco Food Ingerdients. This is a milk fat replacer Ecolact 1903-33 TF with low content of transisomeres

Specialists of the All Russia Dairy Research Institute have developed starter cultures with low postacidifying activity. The cultures consist of strains combinations that form and do not form viscous coagulum.

In the technogene zone of the Republic North Osetiya-Alaniya supplements toxinil and calcium tetacin were added to cow rations with increased levels of heavy metals. As a result zinc, plumbum and cadmium contents in milk and milk products became lower

Changes of the milk microflora composition in the course of milk treatment by filtration and treatment in the separator-clarifier are discussed.
