Please let me know how you melt, clean and filter your beeswax as it's a dilemma that I'm currently facing and I still haven't decided what piece of kit to buy to do this with the quantities I produce??!!
I use one of these
Wax Cleaner
It can 35kg of wax the volume is just over 2.5 honey buckets(32lb). The most useful thing about this device is you can put soft water in it put a load of wax in and go of and do something more interesting. It is made heavy duty stainless steel with an oil jacket. It has a 3kw and heats wax efficiently, however, I do believe Thomas make a similar device with a rockwool jacket which is cheaper to run. You do pay for the insulation though and I don't know how long it takes to recover the difference!
The Swienty melter works on the sedimentation principle; wax is left for a couple of hours (once molten) for bits in it to either float to the top or sink to the bottom before pouring out the wax. I don't know if Polyhive lets his settle or melts the wax and lets the strainer on the top do the work......
The Swienty one does not come with straining mesh which means crud which floats to the top of the molten wax will have to be removed using a stainless steel sieve. With Polyhives this does not matter as the mesh in the top traps it when you pour out the wax.
If you open the bottom tap with mine you can drain off a proportion of the water so when you open the top tap you get a stream of wax coming off with minimal impurites. However, along the line you will still end up with wax cake with crud on the bottom which needs to be scraped off.
The wax cleaner Polyhive uses has a strainer above the wax. Polyhives cleaner uses hydrostatic pressure to push wax through a material strainer.
His video can be found
here, and photos of the wax cake
here.
I've not used a wax melter like Polyhive's, so I don't know what the maximum beeswax capacity of his melter is.
Mine melter is oil filled and this has meant the heater has had to be tightened several times as there has been slight oil weepage due to extraction and contraction about fibre ring seals next to the heating element. The device came without the heater being attached which caused a few problems as the heater nut is 65mm in diameter and spanners this size are a bit expensive. I used a big hand held adjustable spanner to tighten it up. The oil was an extra few pounds (£100 approx) on top of the price of the cleaner.
Being oil filled and having a 3Kw heater enables mine to heat wax to above 100 degrees Centigrade. Heating the wax enables EFB and Nosema spores to be killed. I'm sure this is also the case with Polyhives too, although I don't know how much attention it needs when being run for extended periods.
As mine has a heated jacket, kitchen paper can be used to wipe crud of the inside of the melter after use while it is still warm.
Mine is expensive, but solidly made, its heavy without oil and heavier with. It's not the sort of thing you'd want to move about very often and you have to be careful of the taps which stick out if you do. If you want to put it in the loft you'd have to drain out all the oil. Poly's is much lighter and therefore easier to move about and put into storage.
Polyhives one should be cheaper to buy, even if you have to get one made to order.
I believe if you put the wax through the twice, (scraping the crud of the bottom) either of the devices mentioned will result in nice clean cakes of wax, and use of gas or electricity for heating is a personal choice.
Hope this helps...
