Grain Roller Mill.
A] Cracking ]
B] Flaking ] For small Ethanol Plant
A] Specification: To be able to run 24 hours/day 7 days per week for 10 months p.a. Grains are sorghum, wheat or barley. First phase cracking rolls the product will be at ambient temperature and approximately 22% moisture content. 3 flow rates of small plant options.
1] 1.5 TPH
2] 3.0 TPH
3] 4.6 TPH
B] Specification: To be able to run 24 hours/day 7 days per week for 10 months p.a. Grains are sorghum, wheat or barley. Second phase flaking rollers similar to a breakfast cereal wheat flake. The product will be at ambient temperature and the moisture content will be to suit the optimum for flaking but approximately 25% to 30% moisture content.
1] 1.6 TPH
2] 3.2 TPH
3] 4.0 TPH
Grain Conditioning
1. 1st stage grain conditioner complete with heated/insulated jacket to be able to pull vacuum and add water/marinade and mix to the following grains: Wheat, barley, sorghum and corn. Raise moisture content from 22% to 30% for three different capacities. Plant to run 24 hpd for 10 months p.a.
A] 1.5 TPH add 100 L/Hr marinade.
B] 3.0 TPH add 200 L/Hr marinade.
C] 4.6 TPH add 300 L/Hr marinade.
Note ？ grain would be lightly cracked (density approximately 550 Kg/m³)
Retention times in vessel minimum 15 minutes/batch say 3 cycles per hour.
2. 2nd stage grain conditioner/hydrolysis unit complete with heated/insulated water jacked to be able to add water/enzyme solution (vacuum not required). Mix with a flaked product/grain. These grains may be ？ wheat, barley, sorghum and corn. The plant to run 24 hours per day and 10 months per year.
3 different capacities.
A] 1.6 TPH adding 267 L/Hr water/enzyme mix.
B] 3.2 TPH adding 534 L/Hr water/enzyme mix.
C] 4.9 TPH adding 800 L/Hr water enzyme mix.
Subject to further tests we expect to need a retention time of 2 hours.
Liquid/Solids ？ Basket Centrifuge ？ self cleaning type.
Capable of taking the treated grain and in the first run (batch) extract starch/glucose broth. Then second run add 2 pulses of chilled water to ensure maximum glucose washed out of grain. As previously we will want to be able to handle any of the grains such as wheat, barley, sorghum and corn. Also we have 3 plant sizes.
A] Input 1.9 TPH add 133 L/Hr 2 stage flush water output of 400 Kg/Hr solids and 1.6 TPH liquid.
B] Input 3.8 TPH add 266 L/Hr 2 stage flush water output of 800 Kg/Hr solids and 3.2 TPH liquid.
C] Input 5.7 TPH add 400 L/Hr 2 stage flush water output of 1200 Kg solids and 4.9 TPH liquid.
Fermenter:
A water jacketed vessel that would be capable of taking a series of batches per hour from the centrifuge of glucose broth, add yeast and yeast booster continuously and using Co2 continuously strip 45% ethanol and recover excess Co2. Operate at low temperature of say <50ºC. Be able to discharge periodically the wet distilled grain solids.
3 different sizes are proposed.
A] 1.6 TPH input stripping 1.3 TPH/45% ethanol with approximately 67 Kg/Hr of WDGS.
B] 3.2 TPH input stripping 2.6 TPH/45% ethanol with approximately 134 Kg/Hr of WDGS.
C] 4.9 TPH input stripping 3.8 TPH/45% ethanol with approximately 200 Kg/Hr of WDGS.
Distillation:
To be able to distil 45% ethanol to 95% ethanol with the minimum of extra heating and cooling preferably an option by using microwave technology. (Standard system would be acceptable).
There are 3 sizes of plant that we require quotes for.
A] Input 1.3 TPH of 45% ethanol for an output of 0.7 TPH of 95% ethanol.
B] Input 2.6 TPH of 45% ethanol for an output of 1.4 TPH of 95% ethanol.
C] Input 3.8 TPH of 45% ethanol for an output of 2.0 TPH of 95% ethanol.
Pervaporation:
A membrane sieve to produce 99.8% dry ethanol from 95% ethanol.
Quote for 3 duties:
A] Input 0.7 TPH 95% ethanol.
B] Input 1.4 TPH 95% ethanol
C] Input 2 TPH 95% ethanol
