Autosampler Design
Our Auto sampler executes the following functions:
- Measurement of volume by using a combination of a stepper motor, belt drive and light barrier. The distillation rate is calculated and is used to control the flask heater
- Detection of maximum volume condition, which triggers a bottle changing.
- A second light barrier, installed at a fixed position, detecting the bottle at lifting position.
- A balance weighs the empty bottle and later the filled bottle. By comparing the two weights, the cut weight can be calculated.
- A lifting device with a movable fork system and a pneumatic cylinder taking the bottle from the belt and pressing it into the outlet device of the distillation line.
- A combination of a pressure sensor and three valves can evacuate the bottle to column pressure level or can pressurize it with N2 after a cut
Intermediate receivers
Some customers prefer to have an intermediate receiver.
We can supply Standard and Large TBP plants with intermediate receivers of sizes ranging from 250 ml up to 5 litres.
