Description
Technical Field
The utility model belongs to a corn soaking device, in particular to a water-moistening corn detoxification device.
Background
The corn cannot be soaked in the deep processing process of the corn, the quality of the purchased corn raw materials cannot be effectively controlled according to the purchasing standard due to various reasons, so that vomitoxin (vomitoxin) exists in corn steep liquor, and the main component of Deoxynivalenol (DON), the chemical name of which is 3 alpha, 7 alpha, 15-trihydroxy fusarium solani-9-en-8-one, belongs to trichothecene compounds. The pig feed is named after vomiting of pigs and has certain harm effect on human bodies, and the European Union classification standard is a third-level carcinogen. The mycotoxin is present in germs and corn breathing channels thereof, the level of the mildew rate index of the corn is not necessarily directly related to the content of the vomitoxin, and the content of the vomitoxin cannot be judged according to the mildew rate. At present, a soaking solution is used as feeding corn washing and conveying water, and corn is conveyed to a jigger and then conveyed to a soaking tank to enter a sulfurous acid soaking process. Because the vomitoxin content of the soaking solution is very high, the corn steep liquor soaked by sulfurous acid contains vomitoxin, the corn husks without spraying and the soaked meal still remain, the toxin can not be decomposed after spraying and drying, the content of the sprayed corn and the germ meal exceeds the requirement that the content of the sprayed corn and the germ meal is less than or equal to 4.0ppm of a common client, the export is limited, the sale range is reduced, and the sale profit is reduced, thereby being the main problems faced by the current production enterprises.
Disclosure of Invention
The utility model provides a water-moistening method maize detoxification device to solve the remaining problem of vomitoxin after present sulfurous acid soaks.
The utility model adopts the technical proposal that: a feeding scraper conveyor, a feeding rotary screen I, a feeding rotary screen II, a feeding small scraper, a belt scale and a feeding corn washing tank are sequentially connected, the feeding corn dewatering screen is connected with the feeding corn washing tank through a pipeline, the bottoms of the feeding corn dewatering screen and the feeding corn washing tank are respectively connected with the dewatering screen through pipelines, the bottom of the dewatering screen is respectively connected with the feeding corn washing tank and a belt through pipelines, the feeding corn washing tank is respectively connected with a feeding corn washing water pump and a plate frame feeding pump through pipelines, the plate frame feeding pump is connected with a waste liquid plate frame through a pipeline, the feeding corn washing water pump is connected with the feeding corn washing tank through a pipeline, the feeding corn dewatering screen is connected with a jigger through a pipeline, the bottom of the jigger is connected with a sand removing tank through a pipeline, the jigger is also connected with the feeding corn conveying pump through a pipeline, the feeding corn conveying pump is respectively connected with 12 soaking tanks through a pipeline, the feeding corn conveying water tank is connected with the 12 soaking tanks through pipelines respectively, the bottom of the feeding corn conveying water tank is connected with the feeding corn washing water tank through pipelines, the bottom of the 12 soaking tanks is connected with the feeding corn conveying water pump respectively, and the feeding corn conveying water pump is connected with the jigging machine, the feeding corn washing water tank and the plate frame feeding pump through pipelines respectively.
The feeding corn conveying water tank is connected with the clarifying separator, and the clarifying separator is connected with the feeding corn washing water tank and an external process water supplementing pipeline.
The utility model has the advantages that the structure is novel, the vomitoxin of the corn raw material can be effectively removed, the vomitoxin is very easy to dissolve in water, the main source of the toxin in the by-product is corn steep liquor, in order to reduce the toxin content in the corn steep liquor, the feeding corn washing water tank is arranged to temporarily store the feeding corn conveying water, the part of the conveying water is pressed into the feeding corn washing tank during feeding, and the part of the conveying water is pumped back to the feeding corn washing water tank by using a pump after feeding; when detoxification soaking, pumping conveying water in a feeding corn washing water tank into the feeding corn conveying water tank through a clarifying separator, pumping the conveying water into a soaking tank needing to be soaked with water from the feeding corn conveying water tank, washing and soaking the corns, dissolving most of the toxin-containing corns in the water, discharging the soaking water back into the feeding corn washing water tank, recycling the water, periodically discharging the water containing the toxin, supplementing process water, filtering the water containing the toxin by using a plate frame, and discharging filtrate to a sewage station. The soaked soaking tanks are subjected to circulating sulfurous acid soaking after soaking water is drained, and because the washing water and the soaking water for detoxification do not enter the sulfurous acid soaking process, the phenomenon that the toxin in the feeding corn washing and conveying water pollutes corn steep liquor to cause the toxin content in byproducts to exceed the standard is avoided, so that the qualification rate of feed products is ensured, the color is yellow and bright, and the economic benefit is improved.
