Food Calorimeter |
 |
It is used to determine the absolute heat of combustion of foods (calorific values). It may also used to find out relative values of heat of combustion of a series of foods by comparing the rise of temperature of a fixed volume of water when a constant mass of a substance is burnt completely. |
Apparatus Comprises of two assemblies; |
a) Calorimeter Unit b) Base Unit |
The Calorimeter unit carries heat exchanger unit and base unit has crucible holder, ignition system etc. etc. |
a) Calorimeter Unit |
Comprises of a glass water jacket 150 x 80 mm (Ht x dia) surrounding a combustion chamber integral with it and open at its base. This combustion chamber is connected to a copper spiral heat transfer tube. The upper end of this tube passes through a hole in the lid on top and when in use is connected to a filter pump to draw the products of combustion through the copper spiral. A wire stirrer also passes through the cover and a hole with a bored rubber stopper is provided to accommodate a thermometer. Supplied complete with thermometer -5 to + 50°C x 0.10C (Mercury in glass) |
b) Base Unit |
Metal disc about 100 mm dia with a boss for mounting on 12mm retort rod (without rod). The unit works as the base of the combustion chamber and has inlet tubule 6 mm diameter for oxygen supply (oxygen supply is necessary to completely burn the food) and pair of pillars carrying low voltage igniter coil. Also having a moveable crucible support to enable the crucible to raise to the level of igniter coil from outside the assembled apparatus. Supplied without retort stand, crucible or spirit lamp. |
