Introduction: Determine the sample protein content of the nitrogen meter is designed and manufactured according to the Kjeldahl principle, the instrument mainly sample digestion and distillation of the two operating steps, the first half of the operation by the digestion furnace, the latter half of the work process by Distiller to complete, and finally calculated from the titration of the protein content of the test sample. Features: The instrument is equipped with automatic control of distillation software, the use of water, do not need to adjust the water level after boot, automatically generate steam, digester part of the well-type electric furnace core heating to improve the digestion heat effect. Sample digestion, in the digestive tract into the right amount of H2SO4 and samples, and the catalyst selenium into the tube (adding selenium tablets can accelerate the sample digestion and digestion process, shorten the digestion time), digestion escaped from the SO2 and other harmful gases by The exhaust pipe of the digester was drained into the sewer through the exhaust air of the three-way flowing water to effectively inhibit the escape of harmful gases and omit the installation of a poison fume hood in the laboratory. After the entire digestion sample was allowed to pass for 45 minutes About digestion and digestion can be completed. Distiller working water using tap water, the instrument work because of the rising water level in the evaporator electrode so that the electrode current generated steam heated to produce steam, the pressure steam through the digestion of the sample was distilled, the digestion process to produce ammonium sulfate into ammonia And the reaction with boric acid generated ammonium hydrogen borate, a sample distillation process of about 7 minutes to complete the distillation process. Specifications: 1, the determination of varieties: food, food, dairy products, beverages, soil fertilizers, feed and other agricultural and sideline products; 2, the measuring range: nitrogen content of 0.05% -90%; 0.1-200mg nitrogen, test accuracy: relative difference ≤ 2%, parallel difference ≤ 0.2%, recovery rate: 99%; 3, working voltage: AC 220V 50Hz; 4, digestion time: 45 minutes / batch distillation time of 7 minutes / month; 5, power: four-hole digester 1200W; distiller 800W; Eight hole digester 2400W; 6, weight: four-hole digester 9kg; distiller 23kg; Eight hole digester 17kg; 7, volume: four-hole digester 600 × 210 × 180mm3; Eight hole digester 760 × 315 × 170mm3; Distiller 380 × 330 × 820mm3;
