Description
Technical field
The utility model relates to determine nitrogen detection device technical field, and in particular to a kind of condensation of food inspection azotometer
Device.
Background technique
Kjeldahl apparatus be according to the principle of the content constant of nitrogen in protein, by measurement sample in nitrogen content to
Calculate the instrument of protein content.Because the method for its protein content survey calculation is called Kjeldahl's method, therefore referred to as kelvin
Azotometer also known as azotometer, protein testing instrument, crude protein analyzer.Principle: organic compound and sulfuric acid heat together are made wherein
Nitrogen be converted into ammonium sulfate.In this step, potassium sulfate is added into mixture often to improve the boiling point of intermediate product.Sample
The terminal of this analytic process judges very well, because at this moment mixture can become colorless and transparent, is added in obtained solution
A small amount of sodium hydroxide, then distills.Ammonium salt can be converted ammonification by this step.And total ammonia amount can be determined by back titration method: condenser pipe
End can be immersed in boric acid solution.Ammonia can be with acid reaction, and excessive acid can then be dripped under the instruction of methyl orange with sodium carbonate
It is fixed.It titrates resulting result and can be obtained by result multiplied by specific conversion factor.Wherein, after ammonia comes out with steam distillation again
In secondary condensation process, the condensation effect of ammonia is the big factors of influence standard acidometric titration, and traditional condensing unit mostly uses greatly plate
Formula heat exchange, heat exchange efficiency is poor, and volume is big, and energy consumption consumption is more, and exhaust-heat absorption utilization rate is low, and condensation efficiency is not high, wastes money
