Production of high-active dry yeast


Products: High-active dry yeast: powder, wacuum packing, 500 gr boxes 
Raw materials:  starch, phosphate,diastatic enzyme, amilase 
Productivity: 500 kg/day
Production grounds :
Production shop : 48*6 m
pumping plant : 4*12 m
Department of energy : 4*12m 
Number of operators : total - 47 persons, including technical operators (10) control operators (6) workers - (31)
Production technology:
Starch→saccarization→adjustment→sterilization →measuring →liquid additives ←nitrogen and phosphor source 


yeast bacterium→second grade bacterium →third grade bacterium →fan forced dilution of big can →centrifugal devision 



Precise filtering 

high altitude wind →compression of air compressor  →drop of temperature  →separation of oil and water →filtration and sterilization ___________________________________________________________________________|

compression→forming→drying of  boiling layer →vacuum-packing  → high active dry yeast
