At what temp ...

One thing we didn't factor in was the fact that we start morning milking with the overnight milk at 4 deg rather than 3.2.

Dumping a load of hotter milk on top means that by the end of morning milking, the temp is now 1 deg or so above where it used to be at about 6.5- 7.

Doesn't matter too much now as it appears that our collection time has been altered but it does show that for every action there is a reaction

3.5 and start up again at 4.5

When I asked my tank lot about moving it to 4. They said the more frequent startups would be more expensive and reduce condenser life.

Good thinking ...... will pass it on as I am not out until gone 6am these days

(Not sure we have a super cool tbh ......)

As with post above, you need an alternative cooling source as silos have limited surface area compared to conventional.
Point about capacity is valid too in terms of future expansion plans, ability to hold extra milk if tanker doesn't come and cost being relatively negligible assuming no cooling plates.

Yes we have a snap chiller plus a borehole fed plate cooler so milk enters tank at between 6-7 degs and 9hp of dx cooling on silo takes out the rest.
Chiller is cheaper to run than ice builder unless you have a very cheap overnight power rate

Our silo was set at 3.2 but lorry reads 2.25 so it seems we are cooling unnecessarily AND we are on every day collection so I assume setting to 4 shouldn't make the compressors kick in and out too much?
