Coffee percolator is a coffee brewing device that looks like an urn. Coffee percolator, or caffettiera in Italian, may have gotten its name from the word percolate. The percolator was really the first device invented for brewing coffee. Today they are no longer commonly seen and were mostly replaced by drip coffee makers, espresso machines and French press.

Coffee percolators are a cruder way of brewing coffee. Most of the time it exposes the coffee grounds to higher temperatures compared to other brewing methods. This may cause the already brewed coffee to circulate again through the beans. Over extraction can make a coffee taste extra bitter and strong.

Coffee percolator may eliminate part of the volatile compound found in beans. This may result to a release of pleasant aroma during the brewing process but may produce a less flavorful cup of brewed coffee.

Coffee brewed using percolator has a quite distinctive flavor that some people consider as an acquired taste. The proper use of percolator takes a lot of talent so as not to ruin the taste of coffee. Coffee percolator enthusiasts laud the hotter and more robust coffee brewed from this device. They defend that the potential drawback of this method can be eliminated by controlling the brewing process carefully.

There are several parts of a coffee percolator. Starting from the top, it has an opening or spout where it lets someone to pour coffee to a cup or any other container. The lid along the spout is usually made of clear material so you can check on the coffee while it brews.

The percolator also has a perforated chamber designed for holding coarsely ground coffee. And finally, a tube attached to the chamber, runs through the bottom making contact with the chamber that holds water next to a source of heat.

There are two basic types of percolators. The first one pushes pressurized boiling water through the coffee grounds into the chamber. The second one uses gravity in continuously moving the brew through the grounds until the preferred strength is reached.

When using percolator, the required quantity of water is poured into the lower chamber and the desired amount of ground coffee is put in the top chamber. The water level must be lower than the bottom of the chamber for ground coffee.

Place the percolator closest to a heat source such as stove or campfire. The temperature rises making the water in the chamber boil forcing the water up the tube. The hot water goes to the top through the perforated lid of the chamber. It then seeps through the grounds and leaves the chamber through the bottom, going back into the lower part of the percolator. The whole cycle repeats continually.

The overall temperature reaches boiling point while the brew continuously seeps through the grounds. The perking action or the spurting sound of the pot stops and the coffee is ready.

It is necessary for manual percolators to reduce the heat to avoid the coffee of having a bitter taste. Some percolators have a built-in electric heating element that automatically reduces the heat, keeping the coffee warm but not boiling.

Some manufacturers make electric percolators with advanced controls designed to possibly extract the best tasting coffee. It may need some experimentation in brewing the perfect coffee through the use of coffee percolator, so be patient and prepare on having aborted tries.

Handyman tips-the kitchen extractor fan

EXTRACTOR FANS
Most fans are found in bathrooms and kitchens where you either need to expell the stale air out of the room or take
the moisture out of the room,Traditionally the the former applies to the kitchen whilst the latter referes to the
bathroom,but where there is lack of ventillationn in the kitchen then this is a necessary requirement of both functions
in the kitchen.

THE WORKINGS OF A FAN:
When the fan is switched on the blades or impeller which are attached to the electric motor rotate,and as it does,air is drawn
through the blades through the grille at the front of the unit.Most fans can be mounted in two places namely;
1.the window-which requires that you cut a hole in the glass to fit the fan inside,that requires a special cutting
tool that cuts round holes in glass.
2.the wall-this method also requires a large hole saw attached to a drill and depending on the thickness of the
wall to be drilled into can take a long time and be tedious because you cannot force the drill,it has to do the
work by itself with a little effort from you,with this method also you need to insert a tube or hose from the fan to the
outside the sahe lenght as the wall.
It depends on the type of fan you buy because some of them have automatic cut off switches in them that switch off
when the humidity in the room decreases and then switches on again when the humidity increases again.
Some will switch on automatically and some require you to switch them on manually by way of a pull cord in the bathroom.
Most or all fans need to be connected to a fused spur which should be placed near the fan in the case of the kitchen
fitting or outside in the case of the bathroom fitting.
In order for the extractor fan to work properly it needs to be positioned appropriatelly ie at a location where the stale air
leaving the room can be replaced by fresh air,so as the stale humid air is being drawn out to the outside,it is being
replaced with fresh circulating air.
To prevent back siphoning of the expelled air,a self closing grille with shutters must be installed outside,this closes
as soon as the fan is switched off to stop any air from coming back into the room.

SAFETY FIRST
Before trying to clean the fan make sure the electricity is off and the fused connection is switched off.

TROUBLESHOOTING

fan will not work

1.faulty motor-these units ar not replaceable or worth repairing-just buy a new one

2.faulty wiring-with the electricity turned off,check the wiring for loose connections

3.faulty switch-if this is beyond your capabilities then call a service engineer

Noisy or ineficient fan

1.for the fan to work at maximum capacity it needs regular maintenance and that involves removing the casing and using
a a vaccum or an air blower like a pump to remove the dust build up

Oil Extractor: How to use?

I received an oil extractor for Christmas which uses a pump to suck out the old oil from the dipstick of my car. Finally having the time to change my oil I tried the product to which when I put the tube in the dipstick it did not bring out any oil. Of course by the time I tried it out the warranty had already worn out. I tried to push the tube down further but it seemed like something was blocking it from going further. Is there something I’m doing wrong here? I have a 1998 Ford Mustang 3.8L but the pump is supposed to be used for any car. Could I just go through the oil cap instead of the dipstick? Any help will be greatly appreciated…

that system uses different sizes for going thru dipstick tubes. check the dipstick against the tube//see if the tube is longer/shorter and or if the the stick hits and slips in pan to get to sump. i have used thes and you can get 99% of the oil out. also excellant for trans fluid replacement/power steering replacement//try twisting the tube with gentle and or intermittant pressure to get by shelf
