Ready To Eat Food Production
Gunnar Dafgård AB, Sweden
The treatment was done in December 2002.
The problem
Dafgård has very rigorous sanitary rules and some of the production is produced in clean rooms. One of the companies most popular products is Stuffed cabbage leave. The preparation of cabbage leaves has been a headache for years. The cabbage arrives to the preparation line steaming hot and the room is always hot and humid, air temperature 80ºF and RH 90 – 97 %. The production in the adjacent areas requires low temperature for sanitary reason. The walls in the cabbage room are consequently rather cold (64ºF and dew point 77ºF) Condensation water was always running on the walls. The roof had to be dried several times a day to avoid condensation water dripping down on the production line. In spite of daily cleaning and sanitation, mould was forming on walls and ceiling.
Conventional anti-mould paints did not even last a year.
The solution
All walls and ceiling were cleaned from grease and fat and all loose paint was removed. Finally the surfaces were sanitized with KEFA BioWash. All walls were covered with a KEFA Airless coat of 40 mills and the ceiling with a coat of 50 mills. The ventilation was increased in order to allow KEFA Coating to evaporate condensation water during the low moisture load periods.
The result
The last follow up in June 2006 (after 43 months) gave the following result:The workers claim that the indoor climate has improved considerably. The temperature is still 80ºF, but the RH is lower and varies between 70 and 85%. There is no mold and the problem of condensation water forming in the ceiling is gone. The maintenance management is of the opinion that they could reduce the cleaning routines but this would be in violation of the company’s strict maintenance policies.
