and jamie bentley is in charge of the cloud service principally been made in the same way for century a mixture of oil and alkali, we've been making. so here for 150 years. and one of our key ingredients is in this big bulk tank. that's 100 tons of caustic soda. the alkali can react with the oil. on this site, they produce about 30 tons of soak per day around a $100000.00 tons a year. industrialized soap making on this grand scale needs chemistry on a grand scale to and the critical factor is controlling the chemical reaction. mixing, carefully measured quantities in temperature controlled reactors. so in this reactor, we've got palm current oil, which is already in. we're adding the coconut oil, which is the parts of the so that actually creates the phone off to that we're adding caustic soda. ah. the mixture is constantly monitored as it reacts. and about an hour later, the reaction is complete. as we dream is process, once it's reacted, the next stage is to dry, the soap. me in here is a vacuum spray dryer. so the soap that pumped through here we can create a vacuum. stop the water
