Microwave Ovens and Inverters
Interesting Arild, can you expand on that, particulary which types of
applicances
REPLY
Toaster ovens that direct radiant heat into the food are faster than
making a toasted sandwich on a stove top grille.
We had a sunbeam vertical rotisseries having a 600 watt element that
could cook up a pair of cornish hens in little over an hour and the skin
came out crisp but the fat had dripped away. Its a bit like making gyros.
the meat is heated by the vertical radiant heat element and the fat drips
away, The rotissery rotates the meat for an even cooking. Nothing like hot
gyros on a pita bread for lunch. N'est pas??
I am planning to install a tiny sized RCA microwave in the back seat of
our truck and maybe a Koolatron in the box for extended day trips. With a
100 amp Balmar alternator in place of the stock alternator we are ready to
travel.
The koolatron is for keeping the cold cuts chilled on a hot dusty drive
in the mountains. Nothing like foccaci bread and swiss cheese or Black
Forest ham on rye bread garnished with dijon mustard and maybe a slice of
pickle.
Crackers?! you must be kidding! <VBG> . . . well maybe if they are Bretons
with cream cheese and spicy tuna flakes or smoked oysters and a pint of
hummus.

Arild,
Does your friend keep his engine running while cooking and/or keeping his
sleeper warm? What size battery does his truck use to start? Around here,
most tractor-trailer rigs appear to have a battery box containing two
batteries/

I outfitted a friend's long haul truck with a 1750 watt Xantrex inverter
powered from his start battery and in 5 years he never once had a flat
battery. He ran a microwave oven, a bar fridge, an electric frying pan, a
tea kettle and a coffee maker, and a Forman grill not to mention his TV
and radio. No room to install a stove in his sleeper rig.
Items not in use got stowed in the jockey box which only had access from
the outside of the cab.
.
Sorry Arild, I couldn't finish your post. Got hungry and had to go eat...

On the subject of efficiency. I have recently begun
measuring the amount
of electrical energy used by various counter-top appliances
to cook meals.
In most cases they use less energy than the electric stove.

I would expect a stove element and a hotplate element to be equally
(in)efficient for boiling water. Here in Canada, we often use an
electric kettle to boil water - they should be more efficient than a
stove element as the heating element is immersed in the water.

Yep that's pretty standard, two size 8D batteries.
So while the frying pan is on, the engine is idling during cool down but
for the rest he shuts down to comply with the EPA no idling regulations.
I was looking at designing a small DC genset he could use when he has a
two day lay-over. Oversized loads cannot be moved on week-ends in some
states so he is stuck with a layover Saturday - Sunday midnight to
midnight. His alternator is a standard Leece-Neville 160Amp constant
voltage type. In five years he has not had a flat battery. Batteries were
not new when the inverter was installed. During the 5 year period he
replace them once and traded in the truck before needing any further
battery replacement. He uses regular Interstate starter batteries not
something special or Deep cycle.

Anyone who anchors out a great deal tends to live on the battery. DC
appliances have proven to be unreliable and tend to cost more than
equivalent 120V Ac appliances.
Therefore it makes sense to use an inverter to create domestic power and
also use appliances which are energy efficient. Many of the list members
already use a Kill-A-Watt to determine AC power consumption.
In a DC system, a 12V or 24V appliance will have greater line losses
compared to a similar 120V appliance consuming the same number of watts to
do the same work.
Cooking is one of the more energy intensive activities. It can involve a
heating device draining the battery if an inverter is used. Running a
genset to make a cup of coffee or heat a bowl of soup is even more
wasteful and thus expensive. Full time live aboards who anchor out usually
try to stretch the dollars as far as possible.
In recent years much effort has gone into making household current
appliances more energy efficient so it makes sense to take advantage of
it.

I realize that so many folks just have to have a microwave. But, a stove
top or an oven works well, might already be there, and if it isn't, you'll
probably want to install one anyways<
After many years of (relative) silence on this subject, Arild once again
reveals that good food is his first love and electrical stuff just a
hobby:-))
When looking at small, AC appliances don't neglect induction cooking.
High current draw on full power but very efficient so only used for short
periods of time - low Ah consumption.
Safe (no flames, auto cut-offs, controllable, easy to wipe-clean, usually
integral timer, store it in a cupboard when not in use.
Will only work with magnetic saucepans.

Aw! Roger you spoilt my surprise. Induction cooking was going to be my
next posting topic. Right you are about the benefits. Unfortunately these
have not yet caught on as much over here as in Europe. In fact I have been
looking but seen very few of them . What I did find was rather upscale.
And I have not yet found a good induction Wok. All the good woks are hand
formed, beaten iron and heated over a high BTU propane or natural gas
burne. I suspect many trawlerites would be somewaht alarmed at the sight
of six inch high gas flames like you get with a good gaz burner for a
wok.
Arild
No, but after reading all these posts, I'm just going to have to get some of that lectrical stuff you guys are all talking about. Rudy
