METHOD FOR OBTAINING MICROCAPSULATED CHOLINE CHLORIDE FROM ITS WATER SOLUTION Russian patent published in 2018 - IPC A23L33/15 A23K10/30 C07C215/40 

FIELD: agriculture.

SUBSTANCE: after drying, powdered choline chloride is sent for encapsulation by applying a heated gelatine solution to its surface, the heating being carried out with the condensate of spent superheated atmospheric-pressure steam; the resulting capsules are sent to the cooler, from which they are withdrawn as a finished product; for obtaining cold and hot coolant streams, a steam-jet refrigerating machine is used, consisting of an ejector, a condenser represented by an atmospheric-pressure superheater, a heat exchanger-recuperator, a thermostatic valve, a steam generator, wherein the mixture of working steam and ejected vapours after the ejector is sent to the condenser for superheating the atmospheric-pressure steam, and the resulting condensate - into the second section of the air heater, which is then returned to the steam generator to form a recuperation circuit; spent atmospheric air after the heater is fed to the heat exchanger-recuperator for cooling and then divided into two streams, one of which is sent to the condenser to condense the spent superheated flashed steam followed by feeding into the two-sectional air heater, and the other - into the cooler to cool the capsules, and then - into the two-section air heater together with air; after the condenser, it is sent to the dryer with the formation of a closed loop.

EFFECT: finished product positively influencing the rumen microflora during digestion in ruminant animals and having low hygroscopicity due to the use of a gelatine capsule, to obtain material flows with different thermal potential due to the use of a steam-jet refrigerating machine, to reduce specific energy costs due to the heat of spent coolants.
