Guides
Each guide is a filter over the same catalog, so nothing here can claim a unit we have not recorded. Every list says which published figure it is ordered by — none of them are ranked by opinion.
Freeze dryers sized for a family of four
A household of four eats roughly 8–12 lb of fresh produce, meat and leftovers a week that could go through a freeze dryer. A machine that takes 10–20 lb per batch keeps up on one or two runs a week, which is what most people actually manage once the novelty wears off. Below that you are running constantly; above it you are paying for trays you will only fill after a harvest or a bulk buy. The figures are the makers' own per-batch numbers.

The smallest units that fit on a counter
A freeze dryer is a chest freezer's worth of machine in a countertop appliance's clothing, and most kitchen counters have 24 inches of depth and 18 inches of clearance under the cabinets. These are the units whose published dimensions come in under 20 inches wide and 30 inches tall. Check the height against your cabinets before you order — the pump usually sits beside the unit and needs its own space.

220 V units for large batches
Past roughly 30 lb per batch, a freeze dryer outgrows a 110 V household circuit and needs a 220 V line — the same as an electric range or dryer. If you do not already have one where the machine will live, budget for an electrician. These are the units that need it, with the maker's published circuit requirement for each.

Lab benchtop freeze dryers under ~$10,000
Lab freeze dryers are specified by condenser capacity and temperature rather than trays and pounds, and most are sold on quote. These are the benchtop units with a published price under about $10,000 — the ones a small lab, a university teaching bench or a serious home experimenter can actually buy without a sales call.

Price per pound of batch capacity
Sticker price rewards the smallest unit; price per pound of batch capacity rewards the one that gives you the most machine for the money. It is the simplest honest way to compare a small unit against a large one, and it is computed here from the makers' own published price and per-batch figures, nothing else.

Home freeze dryers under ~$3,000
Three thousand dollars is where the entry-level home units sit. Everything here is under that mark at the price we last recorded; the pump column matters, because some units at this price include an oil pump that needs regular changes and others include an oil-free one.
