The Project Production Section listed:

1: Crushing or Milling Section:

The feedstock corn is discharged from the bottom of the silo through an electric valve, conveyed to the crushing workshop by conveyor, and conveyed to the bucket scale by bucket elevator, then to remove impurities in the corn by sieve and stone removal machine. After cleaning, the corn goes into the buffer bin, and then through the iron removal variable frequency feeder to feed into the crusher uniformly. The corn is hit by hammer at a high speed, and qualified powder material enters into the negative pressure bin. The dust in the system is inhaled to the bag filter through a fan. The recovered dust returns to the negative pressure bin, and the clean air is discharged to the outdoor. In addition, the negative pressure bin is equipped with a material level detection alarm, the fan is equipped with a silencer. The whole system operates under the micro negative pressure, with low power consumption and no dust spillover in the working environment. The crushed powder is conveyed to the mixing system by the screw conveyor at the bottom of the negative pressure bin. The mixing system is controlled by computer and the ratio of powder material and water is controlled automatically.


2: Liquefaction & Saccharification process:

Slurry in the mixing tank is conveyed to the hydrocyclone desanding machine by the slurry pump, the slurry after desanding is stored in the temporary storage tank and amylase is added into the tank, then the slurry in the temporary storage tank is conveyed to 1 # 2 # spiral plate heat exchanger by slurry pump, and exchange the heat with the liquefied mash from the later liquefaction tank. The slurry enters into the pre liquefaction tank, and is  conveyed by liquefied mash pump to the spray liquefier for cooking and liquefying, cooking temperature is 105 ºC, liquefying temperature is 95 ºC, liquefaction time is about 120 minutes.

The liquefied mash from the liquefaction tank exchanges the heat with the slurry mash through the spiral plate heat exchanger and its temperature is reduced to 60±2ºC, then the liquefied mash enters into the saccharification tank and add saccharifying enzyme to the tank. The saccharification time is about 30 minutes, the inspection sugar degree of saccharifying mash is 20BX±2BX. Then it is conveyed by the mash pump to the spiral plate heat exchanger in the saccharification section to cool down its temperature to 30ºC±2ºC and then for fermentation in the fermentation tank.

3: Fermentation process:

Batch fermentation, semi-continuous fermentation and continuous fermentation can be employed. To guarantee the stability of fermentation temperature, the heat exchanger outside the fermentation tank is for circulating cooling. Regarding the batch fermentation, at the early stage of the fermentation, fermentation temperature is controlled at about 32 ºC; at the middle stage, temperature shall not exceed 36 ºC; at the late stage, gradually cool down, let  natural fermentation go on  until it ends. Fermentation time is controlled at about 58 + 2 hours. Cassava feedstock fermented alcohol content is controlled above 12% (V/V), corn feedstock fermented alcohol content is controlled above 14% (V/V). CO2 gas overflows with light wine  volatilization during the fermentation, install a light wine collecting device to recover the light wine.

4: Process description of Two-column Differential Pressure Distillation:


The differential pressure of the process unit is: the differential pressure between rectifying column T502 and beer stripping column (mash column) T501.

1,The fermentation mash from fermentation section is preheated to 70 ºC through primary preheater E502 (Fermentation mash is preheated by crude alcohol vapor that is condensed at the top of the mash column), secondary preheater E507 (Fermentation mash is double preheated by waste distillers in mash column), and feed into the mash column at the 24th tray. Fermentation mash is heated by the bottom steam when downward in the mash column T501, alcohol vapor is upward and separated from the waste mash. Waste mash is discharged at the bottom of the column, and the alcohol content of waste mash is no more than 0.05% and transported to the environmental protection section. Upward crude alcohol is for defoaming (low concentration alcohol) by 25th, 26th defoaming plates and enters into 1 # preheater, part of the alcohol vapor is condensed, uncooled alcohol vapor continues to be condensed by a set of condenser. The condensate liquid is heated indirectly by steam condensate water and residual distilling water (waste water at the bottom of the column) of rectifying column and enters into the rectifying column. Part of the crude alcohol refluxes (the purpose is for defoaming the crude alcohol gas), while some non-condensing gas is discharged into the atmosphere through the vacuum pump.

Heating mode of mash column: the alcohol vapor at the top of the rectifying column heats the mash column through the reboiler E501, The reboiler uses a circulating pump for circulation. The mash column works under the negative pressure, the negative pressure is produced by the connection of the vacuum pump through the condenser group.
 
2,Light alcohol from mash column T501 is indirectly heated by the steam condensate water, residual distilling water of rectifying column, enters into the rectifying column at the 18th tray. While the light alcohol is gradually concentrated, head impurities such as methanol and aldehyde are upward with alcohol vapor to the top of the column, part of impurities (such as oil) is retained on the upper layers of the feed plate whereby as fusel oil produced into the fusel oil separator for oil and alcohol separation. Fusel oil enters into fusel oil storage tank V509, and light alcohol enters into light alcohol tank and is pumped to the fermentation mash tank. The head impurities can be removed by extracted part of the reflux as industrial alcohol. The alcohol with a concentration of 95-96% (v/v) in the 6-8 trays below the reflux mouth of the column top is extracted as the finished product, and after cooling, the high concentration alcohol enters into the finished product alcohol tank.
 
Heating mode of rectifying column is heated indirectly by fresh steam through the rectifying column reboiler, and the condensate water is flash steamed and sent to the crude alcohol preheater by the condensate pump for exchanging heat with the crude alcohol and then return to the boiler room for reuse. The flash steam is used as part of the heat source of the beer stripping column.

5: Molecular sieve dehydration technology:

1,Molecular sieve dehydration: 95% (v / v) of liquid alcohol is heated to the proper temperature and pressure by feed pump, preheater, evaporator, and superheater ( For gas alcohol dehydration: 95% (V/V) gas alcohol directly through the superheater, after heating to a certain temperature and pressure ) , and then is dehydrated from top to bottom through the molecular sieve in the adsorption state. The dehydrated anhydrous alcohol gas is discharged from the bottom of the adsorption column, and qualified finished product is obtained after condensation and cooling.

2,Molecular sieve regeneration: After dehydration is completed by the adsorption column, the water absorbed in the molecular sieve is flash-evaporated by vacuum flash evaporation, and then condensed to be light alcohol, the molecular sieve reaches the adsorption state again.

The regeneration of the molecular sieve of the adsorption column is achieved by using the equipment such as vacuum pump, light wine condenser, and regeneration superheater. The regeneration process is divided into: decompression, vacuum extraction, flushing, and pressurize, the running time of each step is automatically controlled by the computer program.

The light alcohol obtained by condensation during the regeneration process is pumped to the light alcohol recovery device.
6: DDGS feed cooling and conveying process

DDGS feed is easy to agglomerate in the process of drying and spraying, and the temperature is as high as above 80 ° c. If only through simple cooling and conveying, caking, mildew, carbonization, spontaneous combustion and other phenomena of the feed will take place after packaging. Our company adopts the industry's advanced two-stage cooling process. First, the DDGS feed is cooled once through negative pressure conveying or mechanical conveying, and then enters into the cooler for secondary cooling (the feed temperature after cooling will not exceed more than 5 ° c compared with the ambient temperature). After cooling, the feed is for crushing and packaging to ensure the feed particle even and no color difference. The process is characterized by high efficiency, energy saving, environmental protection and safety.
