Want the better-documented listing, with a declared weight and warranty? Choose the ZZKD FD-05H. Want the higher batch claim? Choose the HNZXIB FD-05H, after the seller confirms its warranty. Both are sold by HNZXIB under the same model number, FD-05H, and share a -60 °C (-76 °F) cold trap, four trays with 0.46 m² of area, 1,500 W and 110 V. All figures come from the official Amazon listings; we have not run either unit ourselves.

Are they the same freeze dryer?
Possibly, but the listings do not prove it. The shared model number and identical core specs point to the same machine, yet each listing tells a slightly different story.
The ZZKD listing uses ZZKD in its title and as manufacturer, while its brand name and seller are HNZXIB. The HNZXIB FD-05H listing uses HNZXIB throughout, and its part number calls it a laboratory freeze dryer, though it is marketed for home use. Mismatches like this are common in a category with little choice on Amazon.com, which we explain in our freeze dryer hub.
Which one holds more food?
The HNZXIB FD-05H on paper: up to 7 kg (15.4 lb) per batch against 6 kg (13.2 lb). Per tray, that is 1.75 kg against 1.5 kg.
The tray area is identical at 0.46 m², about 5 ft². So the extra kilogram does not come from bigger trays; it comes from a more generous claim. Both listings quote a capacity range, and we use the top of each. In practice, how much you load depends on the food: thin fruit slices and wet stews behave very differently.
Is there any difference in cold trap or vacuum?
No: both declare a -60 °C (-76 °F) cold trap and include a vacuum pump. That is the coldest trap in our US catalog and well past our -50 °C benchmark.
The ZZKD listing describes its pump as rotary vane. The HNZXIB FD-05H lists a vacuum pump and a vacuum hose in the box. Neither says whether the pump needs oil, so check the manual either way. If you want to understand why these two numbers matter so much, see how to choose a freeze dryer.
Which is easier to power and place?
They are equal on power: 1,500 W on 110 V, or about 13.6 A (1,500 ÷ 110). Give either one an outlet on a circuit without other heavy loads.
On placement, only the ZZKD tells you what you are dealing with: 138 kg (304 lb). The HNZXIB FD-05H publishes no weight. With the same model number, plan for a similar mass, and check doorways and floors before delivery.
Running costs are the same too. With home cycles of roughly 20-40 hours, the ceiling is 30-60 kWh per cycle (1,500 × hours ÷ 1,000). Estimate your own with the drying cost calculator.
Which has the better warranty?
The ZZKD FD-05H, because it is the only one that states a warranty: 1 year. The HNZXIB FD-05H listing says nothing.
For a heavy machine with a compressor and a pump, a written warranty matters. If you prefer the HNZXIB listing, ask the seller to confirm the warranty in writing before you order.
Do they list the same uses?
Mostly: both name fruit, candy and emergency storage. The ZZKD adds pet food, fish, milk and camping food; the HNZXIB FD-05H adds meat and seafood.
These are marketing lists, not capabilities that differ between machines with the same specs. Whatever you choose, remember that freeze drying does not cook food. Our guide to freeze-drying at home covers what works and what does not.
What if neither fits?
Look at the HNZXIB 8-tray if you need more trays, but confirm its specs first.
HNZXIB 8-tray freeze dryer -50 °C
8 trays · -50 °C · 8.2 kg/batch
6/10 · DryFoodLab scoreThe HNZXIB 8-tray doubles the tray count and claims up to 8.2 kg per batch, only a little more than the FD-05H units. Its listing is much weaker: the -50 °C cold trap in the title conflicts with the -35 °C model name in the table, and power, voltage and weight are missing. The bullets also read like lab copy shared with other listings. It is only worth considering if the seller confirms the trap temperature in writing.
