This has been a hot topic and has caused a lot of questions to be asked about what i as the farmer need to do. There are only three steps to follow and the 1st step is the most IMPORTANT one :
1. THE MILK PLATE COOLER, very simple , check what temperature your water entering temperature is ( can be taken at any point before the plate) and then check the milk in your vat temperature WITHOUT the refrigeration going (just by turning on the chiller control after the milk is over the Temperature probe).
This will give you the split i.e : 20 deg water / 23 deg milk = 3deg split
If you are getting a 3 degree or less split you are pretty much sorted in this area. If you are outside this split, 4 degs and up there are some big improvements and money best spent in this area.
2. VAT REFRIGERATION, This is a very simple exercise for us to do as we know all the Vat cooling specs and are therefore able to spec the correct one for you. SIZE does count in this area ! . we will maximun your vat refrigeration.
3. ICEBANK, This is the very last area to be addressing, it is your last resort if the above two issues havn't sorted you out for 2018. Reason being the other two combination are the more cost effective way of cooling your milk and also they would have to be done anyways to make a icebank a economic option to run.
## Last but not least ,don't panic !, do your homework on all these things, ask around, as there are some nice flashy brochures out there from companies promising you the world with all sorts of ridiculous cost savings and milk temperature claims which are just not true !.
we have been warmed by our suppliers, that controllers and electrical components of our refrigeration equipment is at risk from bugs. we had 3 controllers last month that we warranted to the customer but did not receive the replacement due to bug infestation, which blew circuits. We will now be disecting controllers on site to make sure the issue wasn't related to bugs, as this is not covered by warranty. THE SUPPLIERS SUGGEST ALL FARMERS SPRAY or TREAT around their refrigeration equipment.
We have been regularly notified of the frequent and increasing prices of refrigerants (this is the gas inside your chiller), by our suppliers.This is all down to the increase in carbon taxes (76% of this is tax !!!) on this product , the bad news is: is that it is escalating at an alarming rate. it is almost at the stage where we are encouraging the purchase of NEW units just incase a 2nd hand install has/develops a nasty leak. it is almost assumed that the refrigerant top up will be more than a price of a new unit.
