A vacuum pan needs its feed brought in and spread evenly, or the boiling runs uneven. A pan feed box takes the feed and delivers it into the pan in a steady, even way.
The feed box sits at the pan and passes the syrup, molasses or magma into it as the strike is boiled.
This guide explains what a pan feed box does, where it fits, and how to keep it reliable.
What a Pan Feed Box Does
A pan feed box takes the feed for the vacuum pan, the syrup, molasses or magma, and delivers it into the pan.
It spreads the feed so it enters the pan evenly rather than in one place, which helps the pan boil evenly.
By feeding the pan in a steady, even way, the feed box helps the strike boil well and the crystals grow evenly.
Where It Fits in the Plant
The pan feed box sits at the vacuum pan, on the line that brings the feed in during boiling.
It fits between the feed supply and the pan, passing the syrup, molasses or magma into the pan as the strike is boiled.
Wherever a vacuum pan is boiled, the feed box is what brings its feed in evenly.
Signs the Pan Feed Box Needs Attention
A feed box in trouble shows up in the feed and the boiling.
- The feed not spread evenly into the pan
- Uneven boiling in the pan
- The feed box worn by the syrup and magma passing through
- Leaks where the feed box joins the pan and the line
- Build up in the feed box that holds back the feed
What Makes a Good Pan Feed Box
A pan feed box is judged by an even feed and hard wearing surfaces.
Even Feed to the Pan
The feed box must spread the feed evenly into the pan. An even feed is what keeps the pan boiling well and the crystals growing evenly.
Hard Wearing Surfaces
Because syrup, molasses and magma pass through it, the feed box must stand up to wear. Hard wearing surfaces keep it feeding the pan for a long run.
Keeping the Pan Feed Box Working
Routine attention keeps the feed box feeding the pan evenly.
- Watch that the feed is spread evenly into the pan
- Check the feed box for wear from the syrup and magma
- Check the joints to the pan and the line for leaks
- Keep the feed box clear of build up that holds back the feed
Common Questions About Pan Feed Box
It feeds the syrup, molasses or magma into a vacuum pan and spreads it so the pan boils evenly.
It sits at the vacuum pan, on the line that brings the feed in during boiling, between the feed supply and the pan.
An even feed keeps the pan boiling well and the crystals growing evenly, while an uneven feed makes the boiling run uneven.
Watching that the feed spreads evenly, checking for wear from the syrup and magma, checking the joints for leaks, and keeping it clear of build up keep the feed box working.
Feed Your Pan Evenly
