The invention discloses a full-automatic evaporation residue / transfer volume measurement system, which comprises a heating evaporation cavity, a cooling measurement cavity, a nitrogen introducing unit, a tail gas recycling unit and a control system, wherein the tail gas recycling unit comprises a tail gas recycling pipe, a top-speed cooling box, a cooling radiator, a cooling tower, a compressor radiator, a refrigerating compressor, a waste liquid collecting pipe and a waste liquid collecting box. The full-automatic evaporation residue / transfer volume measurement system disclosed by the invention has the advantages of automatic feeding, automatic temperature control, automatic gas channel control, automatic motor control, automatic weighing and calculation and automatic alarm which are realized by the control system, full-automatic tests are achieved, and labor cost and time cost are greatly saved; multiple effective protection measures like introducing nitrogen and the like can ensuresafety coefficient of equipment use; waste gas out of a first air exhausting opening and a second air exhausting opening can be treated by the tail gas recycling unit, environment is prevented from being polluted, an environment-friendly requirement can be met, a solvent is prevented from volatilizing in air and exploding when meeting electric spark, and potential safety hazards are eliminated.
Description
technical field [0001] The invention relates to the technical field of evaporation residue measuring equipment, in particular to the technical field of automatic evaporation and measuring equipment that can recover tail gas. Background technique [0002] In the food industry or chemical industry, it is necessary to measure the dissolution rate of various containers and utensils in different soaking liquids to determine whether such utensils are suitable for holding the soaking liquid or food or chemicals containing soaking liquid ingredients. In the chemical industry, the dissolved substance is called evaporation residue, and in the food industry, the current standard is called migration. At present, there are not many devices that can measure evaporation residue / migration, and all of them are manual or semi-automatic devices. The operation is cumbersome, time-consuming and laborious, and the measurement accuracy cannot meet the requirements. [0003] The realization princi...
