The customer challenge
In the hemp plant the cannabinoids are predominantly present as so-called carboxylic acids, however, the active ingredient has its full therapeutic effect only after being heated. Temperature is a critical process condition both during storage of the crude oil as well as in the extraction. Too high or too low temperatures could lead to longer process times or even worse, to the formation of undesirable byproducts whose removal requires an important additional effort.
The TR88 and TM411 temperature sensors measure the process critical temperatures and monitor the correct progression. The pressure in pipes and vessels is monitored by Cerabar PMP55 pressure sensors with diaphragm seal and metallic membrane or Cerabar PMC51 with ceramic membrane. Differential pressure Deltabar FMD71 controls the level in the extraction chamber. Dry run protection in circulation pumps is ensured with Liquiphant FTL5xH . Coriolis flowmeters ensure the correct dosage of the liquids.
