Description
Technical field
The present invention relates to a kind of production system of starch, in particular to a kind of cornstarch system of processing belongs to starch and adds
Work technical field.
Background technique
Traditional corn processing starch uses wet method processing technology, includes the following steps: that 1. use sulfurous acid soak;2. logical
Two-stage corase grinding (having the extraction of level-one plumule after every grade of corase grinding) is crossed, level-one fine grinding grinds material;3. passing through fiber wash for fiber
It extracts;4. starch and albumen are separated by centrifuge;5. starch purification, dehydration, dry, packaging;6. albumen dehydration is done
Dry and packaging;7. germ washing, dehydration, drying and packaging;8. fiber dehydration, dry and packaging.Technique is more mature, flow line
It is almost the same.
Maize peel is made of semipermeable membrane, infiltrates solable matter inside niblet, it is necessary to will be semi-permeable
Film becomes permeable membrane, and corn uses sulfurous acid soak 40-48 hours of 0.15%-0.25%, steeping tank temperature 48- under common process
The protein net of niblet can be destroyed at 53 DEG C, make the starch granules separate out wrapped up by protein net, thus favorably
It is separated in fiber and protein.
Due to plumule to be extracted, traditional handicraft can only be using 2 grades of corase grinding, 1 grade of fine grinding, and needs to extract embryo after corase grinding
Bud, centre have needed the equipment such as surge tank, delivery pump, germ cyclone.Plumule is liquid after extracting, and need to use squeezing machine
Plumule is dewatered to 53% or so, recycling pipe bundle drier that moisture content is dried is 7% moisture.
Starch separator is used as the separation of starch and albumen, in the starch after separation, protein content≤3.5%, then pass through
Protein content is reduced to 0.4% or less by washing swirler.Starch milk desaccharification workshop is liquefied, is saccharified, is filtered, filtered
Albumen is generally directly taken out.
When albumen dehydration is using vacuum drum filter, filter cloth washing is washed using process water, 300 ton/days of jade
Rice producing starch project, washing water need 35m3/h, this part will increase the treating capacity of thickener.
The vacuum pump of vacuum drum and evaporator needs working solution, and 300 ton/days of corn processing starch project needs working solution
10m3/h is generally directly discharged to sewage treatment plant with clear water after.
Pipe bundle drier handles tail gas, fan outlet by negative pressure transportation, Asta-3746 discharging, pulse into cold air, product
Direct emission.
In conclusion wet method processing technology is primarily present following shortcoming: 1. process flows are too long, cause equipment more,
Investment is high, and power consumption is big;2. sulfurous acid soak need to be carried out, soaking time is long, and energy consumption is high, causes water consumption big, sewage quantity
Greatly.
Summary of the invention
It is an object of the present invention to overcome problems of the prior art, a kind of cornstarch system of processing is provided, it can
Acid-producing apparatus, intermediate storage tank, delivery pump, germ cyclone etc. are saved, steeping tank quantity and volume will also greatly reduce, and reduce and steam
Steam consumption.
In order to solve the above technical problems, a kind of cornstarch system of processing of the invention, including fetus device is mentioned, it is described to mention embryo
