A combustion calorimeter can be used to measure animal feed. This sounds crazy at first, but it is widely used. The reason for this is the notion that food calories are not the same as combustible calories. This means that the calories (KJ) written on a food packet are NOT measured in a combustion calorimeter. The food calories are measured by a WET process, which emulates the digestion. The process is lengthy, smelly and messy because the various food groups are separated into the prime food groups such as protein, carbohydrates and fats and then the groups are measured separately.
How is a calorimeter used in food stuff? In a simple comparative way. If the consistency of a food is more or less the same, then the combustion will give comparative results. Fast! The speed by which the result is obtained is the main reason for using a calorimeter.
Take potato chips : The oil is a major factor in potato chips and can be accurately measured in a combustion calorimeter. It is more or less used as a quality assurance tool.
Take animal feed : It is made of by-products. Which of these increases the weight of the animal the most and which passes through the animal? For this the intake of animal feed is measured, then the animal's weight gain, and finally the animal excretes.
To accurately and effectively measure the calories in combustible materials and food stuff we recommend our CAL3K-U and CAL3K-F Oxygen Bomb Calorimeter Systems. These systems are better suited to the application of measuring food calories as well as small combustible samples, and are suited to running fewer samples a day. With it's affordable price and ability to produce accurate results for the above applications these systems are up to the challenge.
The CAL3K-U is the third in the range of Oxygen Bomb Calorimeters from DDS, and features an external oxygen filling station with manual filling. It is best suited for universities, educational institutions and robust handling. The CAL3K-U Calorimeter can perform up to 9 samples per hour using 3 CAL3K Oxygen Bayonet Bomb Vessels.
The CAL3K-F is the fourth in the range of innovative new oxygen bomb calorimeters from DDS. The new range, from the engineers who designed the CAL3K-A Oxygen Bomb Calorimeter range, features higher speeds, improved accuracy, small footprint with the now legendary resource reduction (no water required, lower power consumption, low maintenance).
