The location of the fresh air for the air pretreatment should be far away from the cold water tower and the corn purification workshop, etc. And the location of the air inlet should be higher than 25 meters to avoid high air humidity and dust. The fresh air is cooled and dehumidified and enters the air heat exchanger, and the air is heated by steam as the heat source. After total filtration and membrane filtration, the fresh air is processed into sterilized dry air.

Ion exchange
The lysine dialysate is refined by the continuous ion exchange system, and the eluent with a certain lysine content is obtained, while the wastewater with a certain amount of ammonium sulfate is discharged.

Fermentation
After fermentation, the fermentation broth is heated to a suitable temp for sterilization. Different PH value is adjusted for different kind of natural lysine supplement production.

Membrane filte
After acidulation, the fermentation broth is concentrated and filtered by the membrane system at a suitable temp. The pressure of the centrifugal pump is 0.45MPa. The fermentation liquid flowed along the surface of the membrane at a certain flow rate. The material molecules larger than the molecular weight of the membrane did not pass through the membrane to form the concentrate, which was used as the raw lysine ingredient for the production of 70% lysine sulfate products. Substances or molecules smaller than the interception molecular weight of the membrane pass through the membrane to form the dialysate, which is used as raw material for the production of 98.5% lysine hydrochloride products.

Deamination and evaporation
5)After deamination, evaporation, and concentration of the eluent, the Baume degree of the discharge is 16-18Be, and the PH value is adjusted between 5.0-6.0 by HCl.

Continuous crystallization

The discharged DS of the crystal slurry is 54-56% which has less powder crystal and uniform crystal particles, which reduces the subsequent drying cost.

Centrifuge
The crystal slurry is evenly distributed to the first drum through the distributor by the feed pipe of the separator. The liquid part moves in a circle along with the drum. The centrifugal force generated will collect the mother liquid to the mother liquid collection tank and discharge it to the mother liquid storage tank. The crystal part is deposited on the screen to form the filter cake. The filter cake is pushed into the second-stage drum by the reciprocating motion of the first-stage drum. When the filter cake is pushed to the outlet, the crystal lysine hydrochloride with very low water content is obtained under the greater centrifugal force.

Fluid bed drying
The crystal extract lysine hydrochloride is transported into the fluidized bed dryer after through the vibrating screen. The crystal water of crystal lysine hydrochloride is dried by using a hot blast and draughting air. After multi-stage screening treatment, the 98.5% lysine hydrochloride products with uniform standard particles are obtained.

https://www.jlvadar.com/alcohol-ethanol-production-line/

HongVadar's alcohol production line has the characteristics of small investment, low energy consumption, and low cost. Different qualities of alcohol/ethanol can be obtained from the alcohol production line: premium food-grade alcohol, bioethanol, automobile fuel ethanol, etc. As alcohol production plant, we make beverage grade, commercial grade, industrial technical grade ethyl alcohol and ethanol production from biomass, ethene and molasses, such as industrial strength isopropyl alcohol. Cassava ethanol production and co2 ethanol production are included also.

Alcohol/Ethanol Production Line Process Description
Raw material grinding
Corn raw material from the storage section goes to the crush section by the belt conveyor and bucket elevator. After removing the impurities, it is sent to the hammer mill grinding. After grinding, the cornflour is sent to the middle tank to provide the raw material for the liquefaction through the screw conveyor. This is the first step in alcohol production line.

Liquefaction & saccharification
The cornflour coming from the middle tank is sent to the mixing conveyor after the belt scale. Add the water, high temp. liquefaction enzyme, then to the 1st liquefaction tank. Under the effect of hot water, the cornflour adopts water for swelling. Its structure swells to the loose network structure from a similar crystal state. The first liquefaction tank is used for swelling, enzyme digestion, and viscosity reduction. After sand removing in alcohol production line, part of the mass is returned to the 1st liquefaction tank. Part is sent to the jet cooker.

When the material is sent to the maintenance tube in ethanol production equipment, the material stays for a certain time. The function is to strengthen the liquefaction effect. The material is cooled by flashing. The cooled mash enters the next liquefaction tank from the bottom further liquefaction in ethanol production equipment. Then, the mash is sent to the acid adjusting tank from the top for liquefied enzyme inactivation, then to the heat exchanger to cool to 60℃ for the saccharification. After that and heat exchange, the temp is reduced to the fermentation section.

Fermentation
The mature fermented mash and saccharified mash are pumped separately and enter the fermenting tank at the same time which has been cleaned in advance and cooled after sterilization. The process of adding mash should be controlled during the flourishing period of yeast proliferation in alcohol production equipment, and the process of loading mash should be controlled well to ensure that the mash concentration is within the specified range. The whole fermentation process should be controlled in accordance with the provisions of fermentation temperature, do a good job in the recovery of CO2 and light wine. The road of entering the mash pipe and the fermenter should be washed and sterilized strictly in accordance with the regulations to ensure normal fermentation in alcohol production equipment. After fermentation, the mature mash is pumped into the intermediate tank.

Distillation
The mature mash coming from the fermentation section enters the tray at the top of the crude distillation tower after a heating exchange with the wine gas discharged at the top of the crude distillation tower. Mature mash in the crude distillation tower goes through the plate and mass transfers heat exchange with the rising wine gas in the tower at the same time. Almost all the ethanol of the mature mash change into wine gas. Vinasse from the bottom of the crude distillation tower almost does not contain ethanol, then to the centrifugal separation section of the DDGS workshop. After heat exchanging by wine gas and mature mash, the condensate enters the crude vinasse tank. The condensate enters the crude ethanol tank. The needed energy of the crude distillation tower is provided by the reboiler of the primary distillation tower. After removing some impurities in the purification tower, it enters the rectifying tower for concentration to remove the impurities continuously. The superior ethanol after the methanol removal tower enters the superior ethanol tank in ethanol production machine.

High protein feed
The vinasse from the crude distillation tower bottom is sent to the decanter for centrifugal separation after sand removing, then to the evaporator in ethanol production machine. The concentrate is sent to the dryer. After cooling, it is sent to the feed product tank.

Waste water treatment
Alcohol production plant make the 2nd condensate after evaporation and tank washing water mixed in the mixing pool, then it is mixed with the digestive reflux liquid and added alkali into the acidizing regulating tank to adjust the PH value, then to the UASB unit for anaerobic fermentation. The pure biogas is got after separating by the gas-water separator, then store in the biogas storage tank. The anaerobic sludge obtained from UASB enters the sludge storage tank, and after adding flocculant, it is filtered by the filter press to obtain dry sludge effluent. One part of the digestion fluid obtained from the UASB unit goes back into the acidizing regulating pool, the other part goes into the air flotation unit, and the supernatant in the air flotation unit goes into the water collecting distribution pool, and then goes into the SBR reactor from the water collecting distribution pool, and then through the overflow well to discharge. The sludge from the lower part of the air flotation device and the aerobic sludge from the SBR device go into the sludge storage tank together.

The production capacity is diversified from 10000 tons per year to 600000 tons per year.

If you want to buy wheat starch, high yield and high-quality wheat flour and wheat starch for sale can be obtained from the HongVadar wheat starch suppliers. The whole wheat starch production line achieves zero-emission.

Wheat Starch Production Line Process Description
Slurry adjustment & homogenization
From the flour silo, the raw wheat flour same as wheat starch is quantitatively transported to the flour mixer, and appropriate warm water is added to the mix to form the dough. After homogenizing in the homogenizer, the dough is matured and the protein network is rapidly condensed, which is convenient for the separation of the following procedures.

Tri-canter centrifugal separation
The homogenized pulp enters into the tri-canter, and the light phase, middle phase, and heavy phase are separated according to the difference of density. The light phase is dominated by soluble substances, and the proportion of pentosan is relatively small, mainly distributed in the light phase. This kind of sticky material is separated from the gluten at the first, which reduces the freshwater needed in the process, and the subsequent gluten separation and product quality will not be affected by pentosan. The middle phase consisted mainly of B-starch, gluten, and a little fiber. The heavy phase is mainly A-starch and fiber.

Gluten extraction
The gluten phase-out of the tri-canter contains a large number of B - starch and a small amount of fiber, which are needed to be separated by the gluten rotary screen. By adding a certain amount of water, through the gluten screen, large particles such as gluten can not through the sieve seam, small particles such as B - starch, and a small amount of fiber through the sieve seam to achieve the purpose of separation. In order to separate thoroughly, several gluten screens are used in series. Finally, we get a relatively pure wet gluten.

Extraction of A- starch
The heavy-phase material separated from the tri-canter contains A-starch, fiber, and part of broken gluten mainly. First, the broken gluten is recovered through the gluten screen to improve the yield of the gluten product. Then, the separation of A-starch and fiber was completed by centrifugal sieve. The separated fibers are sent to the B starch section. A-starch is refined and purified and then dehydrated by A starch peeler centrifuge or vacuum drum filter. The water content after dehydration is only 40%, and then it enters into the starch air dryer device to obtain clean A-starch finally.

Extraction of B- starch
In order to extract as much of the gluten and A starch as possible, the gluten is first passed through the gluten sieve to further recover the gluten. A starch is recovered by the separator. The subsequent B starch is dehydrated and dried to obtain the dried B starch. Or directly to the alcohol workshop as raw materials without dewatering and drying.

A starch drying
The dehydrated starch is transported to the air dryer buffer tank by the conveyor, and the wet starch in the buffer tank is fed into the feeder by the feeders' winch. The feeding qty. is controlled by the VFD. The feeder breaks the wet starch and throws it evenly into the air duct of the air dryer, and mixes it with the hot air. The starch is quickly heat exchanged with the hot air in the starch drying duct, and the water in the starch is quickly vaporized. The cyclone separator is used to separate the gas from the starch, and the tail gas is extracted by the fan. The dried starch is collected by the collection tank, it is screened and treated. The refluxed material on the screen is sent into the buffer tank and the finished starch with qualified fineness is automatically packaged by the packing machine.

Gluten drying
A screw pump is used to feed the wet gluten into the gluten extruder for dehydration treatment. The extruder controls the capacity by adjusting the spindle speed by VFD. The extruded water is sent to the gluten sieve buffer tank through the screw pump. The dehydrated wet gluten is fed into the wet gluten buffer tank, then fed into the gluten crusher for crushing by the screw pump. Purified hot air goes into the gluten dryer. It is fed into the drying tube through the thrower and mixed with the reflux gluten granules and hot air. After the separation by the volute separator, the dried fine particles enter the bag filter, and the larger and more water-containing gluten particles return to the gluten crusher along the inclined pipe. The bag dust collector collects the dried fine granule of gluten and then the granule is transported and distributed to the magnetic separator by the screw conveyor.

The production capacity is diversified from 10000 tons per year to 600000 tons per year.

Tryptophan is an essential amino acid. Essential amino acid tryptophan is widely used in medicine, food, and the feed industry. HongVadar tryptophan production line takes the direct fermentation process to get a high production yield and save cost in tryptophan production.

Tryptophan Production Line Process Description
Fermentation air pre-treatment
The location of the fresh air for air pretreatment should be far away from the cold water tower, the corn purification workshop, etc., and the location of the air inlet should be higher than 25 meters to avoid the place with high air humidity and dust. The fresh air is cooled and dehumidified, and enters the air heat exchanger. The air is heated by steam as the heat source. The fresh air is processed into sterile and dry air by total filtration and membrane filtration.

Strain culture
Thr fermentation of the tryptophan is oxygen-consuming fermentation. Fermented strains for producing purified milk tryptophan were bred by directed mutagenesis and kept in the refrigerator at low temperature. Expansion culture of strain should be carried out before fermentation inoculation in order to restore its vitality and achieve good physiological state. Generally, the expanded culture of strain can be divided into three steps: slope culture, seed culture and final fermentation.

Fermentation
There were bacteria, residual sugars, pigments, colloidal substances and other fermentation byproducts in the tryptophan fermentation broth. Before fermentation, the fermentation broth needs to be heated to 65-75℃ for sterilization and acidified to PH 3.8-4.2. After the fermentation, it is sent to the next stage of filtration and purification process to make purified tryptophan.

Membrane filtration
Ceramic membrane was used to concentrate and filtrate the fermentation broth, and the dialysis water was used to reduce the tryptophan content in the concentrate solution, so as to reduce the loss caused by filtration of ceramic membrane. The substance with the molecules larger than the interception molecular weight of the membrane do not pass through the ceramic membrane and form to bacterial protein, which is added to the mother liquor to produce protein feed product. The dialysate moves on to the next process.

Chromatography
After filtration, the dialysate enters to the chromatography purification system to adsorb tryptophan essential. The impurities in the system are cleaned out with clean water, and the tryptophan essential in the chromatography is replaced to get the target product. The dialysate enters to the deamination system. The ammonia ions in the dialysate are evaporated, then it is condensed into ammonia water for recycling through the condenser.

Evaporation crystallization
After refinery, the dialysate enters the multi-effect evaporation crystallizer to concentrate and crystallize the material. The feed concentration of the evaporator is 2.8-3g/100ml. After the concentration and crystallization, the solid-liquid ratio of the discharge reaches 58-60% and enters the separation process. Evaporated condensed water is for fermentation liquid blending, steam condensate is recycled by the power plant to save the cost.

Centrifugal separation
The crystal slurry is evenly distributed to the first drum through the distributor by the feed pipe of the separator. The liquid part moves in a circle with the drum. The centrifugal force generated will collect the mother liquid to the mother liquid collection tank and discharge it to the mother liquid storage tank. The crystal part is deposited on the screen to form the filter cake. The filter cake is pushed into the second-stage drum by the reciprocating motion of the first-stage drum. When the filter cake is pushed to the outlet, the crystal tryptophan with very low water content is obtained under greater centrifugal force.

Fluidized bed drying system
The crystal tryptophan is transferred into the fluidized bed dryer through the vibrating screen, and the crystal water of the crystal tryptophan is dried by hot blast and draught air. After multi-stage screening treatment, the uniform particle tryptophan products are obtained.

Starch slurry adjusting
The commercial starch is sent to the starch dissolving tank first, then to the starch slurry adjusting tank by the pump to monitor the flow rate of starch slurry, DS, PH, and enzyme feeding qty. on line, then to the jet cooker by a centrifugal pump.

Jet cooking & liquefaction
Adopt once jet cooking, twice flashing cooling technology. Clear liquefied liquid and good protein flocculation can meet the requirements of different maltose products.

Filtration
The protein was removed by membrane filtration. After that, the syrup contained a small amount of protein and chromophore. The production of the syrup with the same quality could not only reduce the active carbon, but also improve the quality of the filtered syrup.

I.E.
The syrup solution from filtration treatment is cooled by plate heat exchanger and circulating water, and then passes through precise filtration, 1st cation column, 1st anion column, 2nd cation column and 2nd anion column successively. The cation column is filled with cation resin. cations such as odium ions and calcium ions, etc. in NaCl and CaCl2, can be replaced by H+. The anion column is filled with anion resin, and anions such as SO42- and Cl- are exchanged by OH- on the anion resin. Control the discharge electrical conductivity and pH value. If the electrical conductivity exceeds the control index, should replace another set of I.E. column. The column needs to be regenerated for use.

Decoloring
The purpose of decolorization is to use the adsorption property of activated carbon to reduce the color of the material and the content of proteins and inorganic salts. After ion exchange, the glucose enters the decolorization tank for decoloring, then sent to the filter, so that the activated carbon and liquid glucose separated.

Adjusting
The wet glucose separated by the centrifuge is dissolved by the softened water and steam. Then pump to the glucose storage tank in the sorbitol production process reaction workshop to mix with sweet water or RO water to form the glucose solution with DS=45-55%.

Pressurized by a hydrogen compressor, it enters into a hydrogen high-pressure storage tank to provide the raw hydrogen for the hydrogenation reaction.

Hydrogenation
Pump the fixed amount of prepared glucose solution and nickel catalyst into the reactor. Feed the NaOH solution. Through the steam to raise the temp. add the hydrogen to improve the pres. Under the action of a nickel, catalyst to produce the crude sorbitol production from glucose.

Catalyst separation
Use the residual stress after hydrogenation to take the sorbitol manufacturing plant containing the catalyst into the catalyst sedimentation tank through the liquid-gas separator to precipitate the catalyst of the solution. The supernatant pump into the magnetic filter to adsorb the residual catalyst, then the clarified material is sent to the filter to reuse.

Refinery
There are trace amounts of nickel, calcium, magnesium, chlorine etc. ions and impurities in the filtered sorbitol solution. The excess ions in the sorbitol solution are removed by ion exchange column. Through the mixed bed refining for deepening processing. After the ion exchange and mixed bed treatment, the sorbitol solution passes through the bag filter to obtain the sorbitol solution with pure and lower concentration, and then enters the evaporation feed tank.

Evaporation
For the refined sorbitol solution, the concentration is lower. It goes through the two bag filters to remove the impurities again, then to the multi effects falling film evaporator for evaporation to get the qualified sorbitol solution product with a competitive sorbitol powder price and meet the customers' requirements.
