I want to say the product reduces the "human handling time" from 1 hours to 5 minutes. I googled "human handling time" (the whole phrase), but only 21 results are shown. What I should use to replace "human handling time"?

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form.

In industry, we refer to touch labor, which refers to the amount of manual labor required to perform a task or produce something. This translates into cost, as reducing touch labor reduces the 'human handling time' and the associated costs for that labor.
You can also find similar terms, such as touch time.
There is also interest in the activity itself (not the time), which may be referred to as manual handling.
There are other concerns, besides labor cost, associated with manual handling or touch labor, including safety for the worker and how touching might affect the quality of the product (including the introduction of germs or the likelihood of increasing production mistakes).
Do you have any specific concern that's not covered here?
