Dairy Floor Cleaning
The requirement for a high level of sanitation and hygiene in the dairy industry is obvious. The fact that we can consume our milk without fear of contamination is down to the controls and advances in science and cleaning technology. It has been a long road and hard lessons have been learned in reaching the current standards dating back to the middle of the 19th Century when the first laws were passed regarding food standards. At all stages in the production of dairy products there are strict codes of practice, and hygiene is nowhere more important than in the dairy itself.
Milk has always had the possibility of being adulterated or watered down and this was addressed by a report in the Lancet in the early 1850’s which investigated the composition of some staple foods and found amongst others that milk had been diluted and tea had up to half its weight made up of iron filings. This resulted in the Food Adulteration Acts of the 1870’s. The urbanization of the country following the industrial revolution meant that often dairies were situated in towns and cities and they were often unsanitary and a health risk. The development of the railways and improved roads meant that the dairy could be situated at or near the farm which was the start of the modern dairy.
Dairy Floor Cleaning – Why do it?
The potential for contamination of milk is well known and often learned form bitter past experience. The cleanliness of the dairy is paramount and dairy floor cleaning forms part of the regime to ensure the hygiene standard is adequate. Cleaning up at each milking takes between 30 and 60 minutes and as cows are milked twice or possibly three times a day it is a significant proportion of the working day. Cleaning the milking machinery is a largely automated process either by reverse flushing the system or a jetter system where a separate line is installed to introduce water and cleaning agents into the system. The dairy floor cleaning part of the process is less automated but there are machines to assist.
Dairy Floor Cleaning – Types of machine.
A dairy floor should be well drained and be impervious to water to enable it to be easily washed with water. The floor will, after milking, have a large amount of faecal matter on it and its removal is the first step in effective cleaning. The use of a high pressure washer in this situation is obviously not ideal so a machine has been developed that uses a high volume of water at a low pressure. BG have designed a dairy floor cleaning machine uses 50 litres of water at a pressure of 9 bar to wash away the unwanted residue. Once this has been done then a high pressure washer with a chemical sanitising agent can be used to deep clean the area.
