Description
Technical field
This utility model relates to technical field of aquatic product processing, specifically, is a kind of high-quality fish flour processing unit (plant).
Background technology
Fish flour is by the fish material high protein feed rich in vitamin after steaming and decocting, squeezing, dry, grinding and processing, is used for raise poultry and domestic animal.That fish flour produces in order that destroy cell tissue, precipitate out oils and fats, it is suppressed that the activity of enzyme, reduce the breeding of microorganism, it is simple to storage uses.The processing of present stage fish flour adopts wet method processing technology mostly, and in the course of processing, quality of fishmeal is had a significant impact by steaming and decocting and dry link.Wherein steaming and decocting Absent measures is improper, and fish meal protein can be caused to run off；Long-time steam high temperature drying in dry link, can cause fish meal protein to go bad, the problems such as vitamin content is unstable.
Protein is the important indicator of fish flour nutritional quality, and fish meal protein content is more high, and quality is more good；In fish flour, fat content is unsuitable too high, the fish oil oxidative rancidity based on unsaturated fatty acid otherwise can be caused to react, and cause the shortage of VA and VE, cause that quality of fishmeal declines, and fat oxidation heats up simultaneously, causes fish flour spontaneous combustion.In fish flour manufacturing procedure, the principal element affecting fish flour quality is steaming and decocting and drying process.Due to fatty,fiss oxidizing property, containing more high unsaturated fatty acid, its oxidation rate is more faster than other animal and plant fat, and therefore fish flour is extremely oxidized easily；Next heat in the fish flour course of processing can promote the fat oxidation in fish flour, and (steaming and decocting is all use high-temperature steam with drying；Also friction generates heat in squeezing, pulverizing etc. simultaneously).(1) steaming and decocting: the effect of steaming and decocting is to make protein receptor thermocoagulation in raw material, destroys its cell tissue, and promotion profit separates with protein；Secondly steaming and decocting energy sterilization and anticorrosion, the enzyme in fish body, the microorganism being attached on fish body is heated destroyed.The parameters such as time in digestion process, temperature, steam pressure all affect the quality of fish flour.Generally, the optimal temperature of steaming and decocting is 80-95 DEG C, and in the flesh of fish of now steaming and decocting, insoluble protein maintains most high-load, and isolated fish oil also can reach the highest content.The steaming and decocting optimum time is 15-40min, if digestion time is not enough, oils and fats is difficult to separate and extrudes, and in fish flour, fish oil residual quantity raises, and affects quality of fishmeal；Digestion time is long, protein degradation, causes that quality of fishmeal declines.(2) drying machine is most critical equipment in fish flour complete set of equipments, its function is that squeezing cake is dried into fish flour, its power consumption and thermal energy consumption are all the highest in a complete set of equipment, and the economic benefit impact that therefore fish flour is processed by the quality of dryer design is very big；The heat drying mode of current fish flour mainly has the mode of straight fire drying and drying with steam；Straight fire drying device structure is simple, and quick heating, energy consumption are low and unit interval interior process sample is many, but temperature high (100-600 DEG C) easily makes material hot-spot, destroys nutritional labeling；Drying with steam is to be heated with steam for medium indirectly mode, dries temperature and is generally 90-130 DEG C, the fish flour quality better that steam drying is produced, but energy consumption is high, and production capacity is low.
Chinese patent literature 2013103012792 discloses a kind of high yield environment-friendly type fish flour fish oil apparatus for production line, including fish flour line production system, fish oil line production system, steam supply system, exhaust treatment system and economic benefits and social benefits waste gas concentration systems；Wherein fish flour line production system includes by the through successively raw material cabin of conveyer device, metal detection machine, precooker, compressor, low-temperature drying machine, sieving machine, pulverizer, cooler and automatic packaging system；The fish oil that this serial equipment produces meets food grade fish oil standard, and the waste gas discharged and waste water all have passed through environmental protection treatment, and discharge index all meets environmental requirement, and its system structure is completely reasonable, and the quality of fish flour and fish oil is higher.Chinese patent 2014204932405 discloses a kind of fish flour and makes production line, including the raw material cabin being sequentially connected with, fish flour steaming plant, fish flour pressing device, Moisture separation device, twin-stage drying device, transmission system, fish flour chiller, filter screen device, automatic packing apparatus and waste gas purification apparatus；This production line can effectively absorb its internal oxious component, promotes fish flour and produces quality.Above-mentioned patent fish flour processing unit (plant) is all promote fish flour quality by improvement emission-control equipment.And it is known that fish flour processing steaming and decocting and dry link, machinery input heat can promote the fat oxidation in fish flour；In steaming and decocting link, if digestion time is not enough, oils and fats is difficult to isolate, and in fish flour, fish oil residual quantity raises, and affects quality of fishmeal, if digestion time is long, and protein degradation, cause that quality of fishmeal declines；The problems such as fish flour oxidation, protein denaturization, vitamin content reduction are easily produced in dry link, as long in drying time, the protein-loss of fish material can be caused, fat content raises.Prior art commonly uses Artificial Control steaming and decocting and dry processing environment, if this link controls improper meeting and causes fish meal protein to run off, the problems such as vitamin content is unstable.In sum, for the shortcoming of prior art, need a kind of fish flour processing unit (plant) that can accurately regulate steaming and decocting and dry processing environment badly, and yet there are no report about this kind of device.
