Currently, the production facility is served by eight specially designed air conditioning units. This configuration is dictated by technological requirements. Each unit maintains optimal microclimate parameters, which vary significantly depending on the functions performed in the serviced room. All systems provide year-round temperature and humidity control with absolute air purification (all systems are equipped with H13 HEPA filters).
TWH series air conditioning units were used to implement the project. These units are specifically designed for food production, the pharmaceutical sector and the cleanroom sector. The units comply with the requirements of DIN 1946, Part 4, and ONORM H 6020, Part 1, as well as the recommendations of Р NP «АВОК» 7.8–2019 and have the following features:⠀
- Smooth innersurface,⠀
- Easy dismantling of maincomponents,⠀
- Condensate drain nipples,⠀
- Airtight air valves,⠀
- Lighting and inspection windows in serviceablesections,⠀
- sealing of joints with silicone-free insulatingmaterials,⠀
- allmaterials are resistant to disinfectants and moisture absorption. ⠀
Great attention was paid to the distribution of air flows in all serviced production areas. The flows are organised in such a way as to prevent stagnant areas, eliminating the possibility of a bactericidal environment. Moreover, since the technology imposes strict requirements on the speed and distribution of air flows, the air speed in the working area must not exceed 0.15 m/s.
This is particularly challenging, as the air exchange rate in most workshops complies with the requirements of ISO 8 according to GOST ISO 14644-1, i.e. it was necessary to distribute a very large volume of air at a very low speed uniformly throughout the entire working area. For this purpose, hygienic textile air ducts manufactured in Denmark and specially designed for this project were used.
Since all production workshops are subject to mandatory sanitary treatment, air is removed through OPFA series stainless steel exhaust separators.
The refrigeration circuit system also requires special attention. To support the process cooling system and operate the ventilation system, we developed a chiller with multiple operating modes. Depending on the mode, the chiller can cool the liquid to +3 °C (main mode) or to –2 °C (in case of failure of the process chiller).
The control system was implemented using freely programmable Trim 5 controllers manufactured domestically.
Thanks to the work, production in the village of Verkhovaya can easily be certified according to the most stringent rGHP (Good Hygiene Practice) requirements – a food quality and safety assurance system based on a combination of ISO 9001:2008 and GMP standards.
In conclusion, it can be said that there are indeed premium cheese producers in Russia who put the quality of their products first.
