Frequently asked questions

What is the initial moisture of a pear?
Usually 80–85 %; more precisely measured with a moisture meter on your batch.

The calculations are approximate: they help to assess the process and compare options, but do not replace a process design and trials on a specific raw material. This section is for reference only and contains no commercial offers.
