Abstract
A closed-loop cyclic utilization technology for the technological water in the procedure of preparing corn starch is disclosed. After the technological water is used to prepare sulfurous acid and immerse corn grains in it, it flows in technological water pool behind evaporation, condensing and regulating pH value. The technological water is also used for coarse grinding, fine grinding, and washing germinal buds and fibers. After two-stage air-floating separation, the water containing bran flows in protein depositing tank. The supernatant is drained in technological water pool and the protein deposit is recovered.
Description
Affiliated technical field
The present invention relates to the technical field of waste water cycling and reutilization in a kind of cornstarch process.
Background technology
The cornstarch process is that corn is through cleaning impurity, sending into steeping tank soaks at a certain temperature, adopt sulfurous acid aqueous solution soaking corn, can well soften corn kernel, the stripping solable matter, the albumen substrate that disperses embedded starch, corn after the immersion is sent into degerming mill, broken seed, and plumule dissociates, isolated plumule is washed, drying, obtains the finished product maize germ.
Behind correct grinding, the protein and the starch that adhere on the fiber are removed, and screen washing back fiber carries out drying and obtains fibrous residue.
The starch milk that contains starch and protein enters seperator to be separated, and isolated protein concentrates, drying, obtains the finished product albumen powder.Starch is through further obtaining pure starch milk after the washing, and starch milk obtains dried starch through super-dry.
Corn is through behind the dry cleaning, drop into steeping tank, soak water and be about 1.5-2.0m3/ ton starch, be mainly used in relieving haperacidity, carry out the thickness mill with corn after grinding Duan Jiashui, use clear water 2m3/ ton starch approximately, the fiber wash process water is about 4m3/ ton starch, the eddy flow washing procedure is about 3.5m3/ ton starch with the clear water amount, enter starch dewatered drying workshop section behind the starch slurry separating spiral-flow, whole process water consumption is about 10m3/ ton starch, and the present state-of-the-art waste water treatment mode of starch industry is that the waste water that starch discharges is passed through anaerobism, methods such as Aerobic Process for Treatment are administered, but this scheme equipment needed thereby investment is big, and form secondary pollution easily, the introduction of starch close circulation technology has also been arranged at present, but effectively that the albumen and the sulfiting of fresh water (FW) is thorough owing to not having, influence starch quality easily.
Summary of the invention
The purpose of this invention is to provide the closed cycle of a kind of cornstarch process fresh water (FW) and utilize technology, this technology can be processed fresh water (FW) separately and be handled back repetitive cycling utilization.
For the present invention that achieves the above object is that a kind of cornstarch process fresh water (FW) closed cycle that realizes like this utilizes technology, carry out the removal of impurities of following operation maize raw material dry cleaning, corn soaking, corn washing, corn screening, corn corase grind, germ separation, corn fine grinding, fiber separation washing, Protein Separation, eddy flow washing, starch dehydration, starch oven dry, screening successively, it is characterized in that:
---the process water pond of storage process water is set;
---required sulfurous acid prepares water and soak water of maize use fresh water (FW) in the corn soaking operation; Soak the rare corn steep liquor in back through the triple effect evaporator evaporation, concentrate, evaporation condensed water is regulated pH value and enter process water pond after between the 4-7,
---washing process, fiber wash water in corn corase grind, corn fine grinding operation and the germ separation all use the fresh water (FW) in the process water pond; The waste water that washing in the germ separation, the process of extracting produce all is back to use the corase grind process;
---the waste water that fiber wash, the process of extracting produce enters separation circuit through behind the plate-frame filtering with thick starch slurry, the isolated seitan water of seperator enters the albumen precipitation jar after separating through secondary air-floatation, precipitation entered process water pond with supernatant after 3-7 hour, precipitated liquid mixes with air supporting liquid laggardly to go into sheet frame and filter, and crosses cleaner liquid and enters process water pond;
---enter the eddy flow washing procedure after the starch slurry process seperator operation, obtain finished product starch through starch dehydration, pneumatic conveying drying oven dry after the use clear water washs.
When the fresh water (FW) dry is increased to 1%-3% fresh water (FW) is recycled to the albumen precipitation jar, adopts flocculant to carry out sedimentation, clear liquid is back to use process water pond, and sediment is sneaked into seitan water separator becomes the albumen powder finished product through plate-frame filtering, tube bank drying.
Advantage of the present invention and good effect are: utilize the very fresh water (FW) of reasonable use starch technical process generation of process of the present invention, fresh water (FW) is processed separately and is handled back repetitive cycling utilization, greatly reduce water consumption, the water consumption of whole technology is discharged into the water vapour amount in the atmosphere when being product drying, and the operation of interpolation clear water only is the addition of starch eddy flow washing procedure.This technology is effectively guaranteeing under the product quality premise of starch product, greatly reduces the water consumption of starch production, simultaneously because technical process sewage effluent not, do not form pollution, compare with sewage disposal, can not form secondary pollution, can improve the dry yield of byproduct simultaneously.
Description of drawings
Fig. 1 is a process chart of the present invention.
The specific embodiment
Whole technology as shown in the figure, corn is transported to and soaks the workshop and soak through living together reason back dry method clearly, soaking the workshop water mainly is the relieving haperacidity water, relieving haperacidity does not influence the immersion effect with fresh water (FW), soak the rare corn steep liquor in back and carry out triple effect evaporation, the condensed water that produces in the corn steep liquor evaporation process turns back to process water pond by adjusting pH value after between the 4-7, soaking the back corn delivers to the abrasive material operation with fresh water (FW) and grinds, the section of grinding is extracted maize germ, will use the water of process water pond during germ washing, the waste water that germ washing, the process of extracting produce all is back to use the corase grind process.The fiber wash water is fresh water (FW), the waste water that washing, the process of extracting produce is owing to contain a certain amount of fine fibre, can not direct reuse, enter separation circuit through behind the plate-frame filtering with thick starch slurry, the isolated seitan water of seperator enters the albumen precipitation jar after separating through secondary air-floatation, precipitation entered process water pond with supernatant after 3-7 hour, and precipitated liquid is mixed the laggard sheet frame filtration of going into air supporting liquid, and the mistake cleaner liquid enters process water pond.Enter the eddy flow washing procedure after the starch slurry process seperator operation, this operation must use clear water to wash, otherwise can't guarantee the SO 2 index of product.Obtain finished product starch through starch dehydration, pneumatic conveying drying oven dry at last.
Fresh water (FW) is through after a while circulation, dry will be increased between the 1%-3%, when the time comes fresh water (FW) is recycled to the albumen precipitation jar, adopts flocculant to carry out sedimentation, clear liquid is back to use process water pond, and sediment is sneaked into seitan water separator becomes the albumen powder finished product through plate-frame filtering, tube bank drying.
