Right commercial oven for Frozen Foods? I'd like to provide an array of meals that are frozen and can be quickly heated and served. I have reviewed different models and there are 3 kinds I think:

1) Steam Combi - e.g. Rational selfcookingcentre

2) Convection+Impingement- e.g. MerryChef E2S
 ﻿
3) Convection + Microvave e.g. Menumaster

The menu would consist of the following types of food:
Lasagna
Pasta
Rice
Noodles
Curries

Objective is To be able to put frozen food directly into the oven (without thawing) and using a particular setting for each item type, the oven should be able to bring it 'closest' to freshly cooked food w.r.t. texture especially.. in under 10min.

Thanks,
Nipun
The Rational oven is definitely more flexible - it usually offers a dry and a wet oven capacity. If you're reheating any wet ingredients like pasta, rice, sauces, you'll find the merry chef very unsuitable.

Options 2 and 3 that you've listed are good for far reheating of relatively small numbers of portions that need heat + crisp eg pies, roast potatoes. But they're not so good for wet foods or large batches
