Central Manati 



Manati Sugar Company — Central "Manati" 



Improvements Made in the Machinery of the Central Manati 



At the present time, the grinding plant of the Central Manati consists of 3 Tandems, 

 two of which are composed of three crushers and five mills each, and the other one, of one 

 crusher and four mills. This is the oldest Tandem, and this year two more crushers 

 will be added to it, being converted into a Tandem with three crushers and four mills. 



Manati is the first plantation in the world where three crushers have been used, 

 and by the results obtained with this season's crop, the advantage of this system 

 has been proved. 



At the present time this Central can grind 750,000 arrobas (25 lbs.) of cane daily, 

 and next year, after the old Tandem is equipped with two more crushers, it will be able 

 to grind 850,000 arrobas. 



The Central Manati in the last crop exceeded the record of the daily grinding in 

 the world, grinding 730,000 arrobas of cane in 23 hours and 43 minutes. 



The Boiler Plant consists of 26 multitubular boilers of 375 H.P. each and 4 Edge 

 Moore boilers with water tubes of 1,000 H. P. each. These boilers work at a pressure of 

 110 lbs. for the Central and 150 lbs. for the Electric Plant. The 26 multitubular boilers 

 use as fuel the bagasse from the mills, and the 4 Edge Moore boilers use bagasse and 

 petroleum. 



The clarifying equipment consists of 5 cane juice heaters and two series of circular 

 tanks with conical bottom and steam coils to decant the juice. 



Two Dorr apparatus of continuous clarifying have been installed on trial, which 

 have given good results, and the idea for the future is to substitute the tanks with this 

 type of apparatus. 



To filter the first froth of the cane juice, 27 press filters of 36" have been installed.
