    Default Covering your evaporator

    Hi all,

    I am a first year producer, 100 taps, 2x6 evaporator.

    I am wondering if people covers their evaporator at night after boiling because i am concerned with rodents. For those of you who do, what do you use ?

    Thanks a lot

    Never had problems with rodents, but we covered ours with a sheet of plywood and a big brick on top to keep the wind from blowing it off.

    I have a tight hood on my flue pan and I made a SS cover that is put on the syrup pan. Also each side box has it's own SS cover. I also did that on my 2x6 finisher and my canner. I don't want to take chances.

    I cover mine when it will sit for several days. I just use a sheet of plastic. so I put it on the day after boiling if it looks like it will be a day or two more before I cook again. the homemade preheater on the flue pan makes it nearly impossible to use a hard cover and still close it up well. I could take that off easy..but then it would not be covered also. this way it is

    Thanks for sharing your experience. I clearly prefer not to take any chance so all your ideas are much appreciated especially as now its too late for having one built in SS so i need alternative ideas for now.

    I built one out of aluminum flashing and pop rivets for this year. Its a little flimsy, but it works for now.

    I use those handled stainless steel covers that go with any particular model of steam table pan. I just put them on the pans and done. The fit isn't always perfect due to heat warpage of the pans, but it isn't too bad.

    Be careful, condensation coming off your pans will be in contact with your cover and dripping back into your syrup.
    I would be leary of anything other than stainless.
