convection oven

The mountains trap hot air and circulate the heat like a convection oven.

Bush, for example, recently listed a Montague Co. convection oven for $9,500 — far below its original price of roughly $21,000.

Revolution Cooking’s $1,800 “macrowave” combines a microwave with a convection oven but such trendy gadgets are typically short-lived and encourage people to trash the simpler appliances they already have, according to Shanika Whitehurst of Consumer Reports.

Dehydrators remove water by exposing ingredients to low heat while keeping air circulating throughout, much like a convection oven but at a temperature that doesn’t actually cook them.

But fans can backfire and turn a room into a convection oven when indoor temperatures exceed about 95 degrees Fahrenheit.
