Description
Technical field
The present invention relates to feed processing technology field, be specifically related to the cooling system that a kind of continous way feedstuff mildew becomes.
Background technology
The animal feed of the large-scale cultivation such as pig, chicken is normally comprised of protein feeds, energy feed, roughage, green forage, ensilage, mineral feed and feed addictive; Category divides: reinforced and premix entirely.Protein feeds comprises vegetable protein feed and the large class of feed contg. animal protein two.Vegetable protein feed has the sub-reality of beans and processed side product, cereal processed side product and oil cake etc.; Feed contg. animal protein comprises blood bone meal, fish meal, silkworm chrysalis etc., is characterized in that protein content is high, is 3-8 times of grain trough.As in usually raising, coarse food grain and energy feed are combined together and are fed pigs, use and suitably can make male and female pig normally breed, promote piglet growth and fattening to increase weight.
Feed is in storage, transportation, sale and use procedure, very easily go mouldy, the mould contamination feed of raised growth and breeding, not only consume the nutriment in feed, feeding quality is declined, the price of deed reduces, thereby and livestock and poultry can cause that diarrhoea, enteritis digestion power reduce after edible, degradation symptom under lymphatic function, serious causes death.
Therefore, how to prevent the food security problem that the Shi Ge state of going mouldy of feed all will face, and the mildew-resistant of feed is fundamentally to solve the effective way that mycotoxin produces.Now current development situation is done to simple a conclusion, domesticly mainly from following several respects, is set about:
1. control raw material moisture.This is the most basic method of mildew-resistant, and going mouldy is all to betide high humidity environment, and General Requirements corn, Chinese sorghum, paddy etc. are no more than 14%; Soybean and grouts thereof, wheat class, inferior powder, sugared bran class.Dehydrated sweet potato, cassava is dry is no more than 13%; Cotton cake dregs, dregs of rapeseed cake, sunflower benevolence grouts, flaxseed grouts, shelled peanut grouts, fish meal, bone meal and meat meal tankage are no more than 12%.
2. keep the freshness of feedstuff.The freshness of raw material is to determine the quality of feed own and the factor of shelf-life.
3. should control moisture and temperature in feed process, preferably apply HACCP quality detecting system.Because mould more easily grows on cereal destroyed or that processed, so that this process seems is particularly important.
4. apply Midew preventive for feed.The product that propionic acid and its esters be main component of take is very effective in mould fungus inhibition growth, and adopt by multiple coordinates by machine acid mould inhibitor the compound anti-virus agent forming by a certain percentage now, to increase anti-mold effect.
Except above method, external production of fodder manufacturer and scientific research personnel, attach great importance to research and the application of Prevention of Mould Development.In recent years, the feedstuff mildew technology of employing mainly contains following several:
Radiation sterilization.Feed, after pulverizing or granulating processing, all can infect some pathogenic bacteria as salmonella and Escherichia coli etc.After U.S. scientific research personnel penetrates chicken feed 10GP ray width, be placed in 30 ℃, the environment of relative humidity 80% and store one month, mould is breeding not; And without the chicken feed of radiation, after same condition and same time storage, go mouldy, width is penetrated feed can reach sterilization effect, can long-term storage and never degenerate.
Add mould inhibitor.The external Midew preventive for feed using is more, as KI, calcium iodate, calcium propionate, formic acid, seawood meal, orange peel ethanol extract etc.According to Japanese scientific and technical personnel's research, multiple mould inhibitor mixing result of use is better, they mix 92% seawood meal (sea mustard powder or Kelp Powder) and 4% calcium iodate, 4% calcium propionate, addition by 8% makes an addition in feed, be placed under 30 ℃, the environment of 100% relative humidity, in one month, can not mildew; And not adding the feed of mould inhibitor, 5d can mildew; Add wherein a kind of feed of mould inhibitor, 10～15d can send out mouldy, and therefore Japan makes efficient feed mildew inhibitor by seawood meal, calcium iodate after mixing.
Use mouldproof packaging, bag.The feed mildewproof packaging bag of Japan scientific research personnel invention, can guarantee that the feed of packaging does not go mouldy for a long time, and this feed mildewproof packaging bag, consists of vistanex, wherein contains 0.01%～0.50% vanillic aldehyde or ethyl vanillin.Because can making vanillic aldehyde or the fragrant aldehyde of ethyl, polyolefin resin film slowly evaporates, and be penetrated in feed, go, can not only mildew-resistant, and because there being fragranced, also can make feed be applicable to the taste of animal, the skin of bag, also covers the film that can prevent vanillic aldehyde or ethyl vanillin diffusion, in vistanex, vanillic aldehyde or ethyl vanillin content are at least 0.01%, and the best is 0.50% left and right.If content is on the low side, fungicidal properties is poor; If too high levels, can affect film forming.
Chemical disinfection and irradiation mildew-resistant.The scientific research personnel of the former Soviet Union thinks, feed is first carried out to chemical disinfection, then carries out radiation, and not only sterilizing, anti-mold effect are good, and can improve the content of vitamin D in feed.They arrive 0.2mm by fodder crushing, add again and be equivalent to the ammoniacal liquor of feed weight 1.2% or 2.0% propionic acid or 2.0% formic acid and carry out chemical treatment, and under the condition of constantly stirring, with the ultraviolet ray that intensity is 120kJ/m, irradiate, can make microbial growth fertility in feed reduce by 99.8%, long term storage can not gone mouldy, and in feed, the fowl amount of vitamin D is also brought up to 180mg/kg, and its effect is all more much better than carrying out chemical disinfection or carry out separately radiation sterilization separately.
Control genetic of fungi password.Feed mold is toward being firmly the pollution that is subject to two kinds of eumycetins of aflatoxin and aspergillus parasiticus, and for preventing the biosynthesis of aflatoxin, available genetic method changes fungi, makes it lose the enzyme that produces aflatoxin.Those are changed the fungi of factory, can successfully be at war with unaltered aspergillus, to control the pollution of aflatoxin to feed.
In sum, current Prevention of Mould Development and method are mainly to control moisture, chemicals or the direct sterilizing of radiation etc. in feed both at home and abroad, some effects are better but cost is higher, also the increase having new composition enter feed its on not further research of institute domesticated animal and eater's impact, new method or technology also emerge in an endless stream, as the researchers of United States Department of Agriculture (USDA) are cultivating the corn variety that can resist aflatoxin, but commercialization also needs the regular hour to marketing.
So-called vacuum pre-cooling technology, also referred to as vacuum cooled, vacuum cooled, due to the difference in used place, is called as respectively now: the calls such as vacuum pre-cooling, vacuum rapid are cooling, vacuum refrigeration, vacuum precooling freshness retaining; At first vacuum cooled is only for fresh-keeping chain the first link-precooling of field agricultural product.Coolingly rapidly meet the requirements of that low temperature just can suppress agricultural product, food causes rotten microbial growth, effect and the respiration of inhibitory enzyme, and can reduce the alcoholic fermentation effect of agricultural product.Vacuum cooled ratio is placed directly in cooling rate in freezer soon and evenly, can keep color and the nutrition of existing product.And the vacuum cooled current the fastest optimal Refrigeration Technique of cooling rate just, it can make agricultural product and the meats such as vegetables, fruit and fresh flower, fish, cure class, the food such as cooked product Quick uniform under vacuum state is cooling, make the quality of product, freshness and nutritive value obtain effectively and safety assurance.Bake and bank up with earth based food and be cooled to 30 ℃ of need 6 ~ 8 minutes from 160 ℃, normal food material is cooled to normal temperature also only to need 10 ~ 15 minutes from 100 ℃, be cooled to 0 ° of C to need below about 25 ~ 28 minutes, be cooled to-18 ° of C to need below, about 35 minutes, to there is as seen high production efficiency; Therefore, this technology is widely used at numerous Food processing manufacture fields.Specifically vacuum pre-cooling refers under normal atmosphere (An) (101.325kPa), and water is 100 ℃ of evaporations, if atmospheric pressure is 610Pa, water is 0 ℃ of just evaporation, and the boiling point of water declines along with the reduction of ambient atmosphere pressure.Boiling is to evaporate rapidly, can absorb hastily heat.Feed is placed in airtight container, deflates rapidly and water vapour, and along with the lasting reduction of pressure, feed is understood because of constantly, transpiring moisture is cooling rapidly.The dehydration of vacuum cooled is generally in 3% left and right, due to pressure differential, pernicious gas and heat in feed granules are also drawn out of thereupon, like this, in vacuum cooled situation, coolingly from granule interior to outer surface, carry out simultaneously, evenly cooling, this is that vacuum cooled institute is exclusive, other any cooling means be all from outer surface to organization internal slowly " infiltration " cooling, thereby the time of guaranteeing the quality is long.Vacuum pre-cooling equipment is a kind of cooling process equipment, is not refrigerating equipment.Its purposes just allows feed etc. be cooled to rapidly the temperature of setting, and then just from equipment, article is taken out, or is placed in air, or directly transport, or put into freezer.Because microorganism etc. is in resting state, the recovery of its vitality needs time course, and this process is exactly the shelf-life, and feed rotten be to surpass more than 12% just easily generation in feed water content, also need the more time.
Although China just starts to have technical research and the device fabrication of vacuum cooled in the middle and later periods eighties 20th century, yet even to this day, domestic have Qia Aina company, Ying Xiang company by Shanghai, the enterprises such as Shenzhen You Wanbao a kind of jade company, Yuan Zhou company are being engaged in the research, development and production of vacuum pre-cooling equipment for a long time, and simultaneously domestic also had a large amount of research works about the practice of vacuum pre-cooling equipment and theoretical side.The purposes of vacuum cooled in agricultural product cooked product process of manufacture: a. greengrocery: leaf vegetables, stem dish, cauliflower, bacterium mushroom dish etc.; B. staple food: rice, noodles, steamed bun, corn, dumpling, sushi, candied fruit etc.; C. poultry: boiling chicken and duck, barbecue chicken and duck, salt solution goose etc.; D. meat-eating race: boiling pig, ox, sheep, rabbit meat etc.; E. fish and shrimp: freshwater fish, ocean fish, shellfish, shrimp, crab etc.; F. fried class: fried food, Deep-fried meatballs etc.; G. bake and bank up with earth class: moon cake, cake, bread etc.; H. fillings class: mooncake filling, rice dumpling stuffing, conditioning food etc.; I. other classes: the cooling and crystalline solid of chemical industry high-temperature material, metal casting molding sand etc.
Feed in common process through shaping particles, packing after 180 ℃ of high-temperature steam sterilization process together, in this operation, there are various bacteria and microorganism, the required higher and sterilizing time of temperature of killing fully just can reach inside and outside one killing rate of making peace, but due to inside and outside uniformity and modified after temperature at 85 ~ 90 ℃, many microorganisms, bacteria living, when high pressure positive blower drops to by force 40 ℃ of left and right of temperature, the water content 15% in last when packing by its temperature, microorganism, bacterial activity ability, fertility are the strongest; On the other hand, feed is from storage and transport process, because the storehouse between feed continues the time that loose temperature need to be longer to normal temperature, in this temperature range, be the period that the vitality such as bacterium are stronger just, particularly during, overcast and rainy state relatively high in environment temperature, weather humidity, for guaranteeing the quality and extending the mildew-resistant time, this is very disadvantageous condition, and feed is rotten at once at shorter shelf life, and it is necessary therefore adopting novel anti-equipment or the technology of going mouldy; Again because modern society is higher to food safety requirements, as most important protein source on human foods chain, the food of animal must be the safe guarantee mankind food security, add the methods such as mould inhibitor not too applicable.
Chen Changqing is in " sealing device of a kind of continuous vacuum (pressure) charging and discharging processing " of invention in 2010, application number is 200510020923.4, adopt hydraulic system as driving, for production of fodder, it is a larger potential safety hazard, in addition, also there is the problem of the following aspects: 1) adopt mode and the working space vacuum chamber of rotary drum less, act on the limited time of material, produce in a large number; 2) this device adopts hydraulic system and liquid storage equipment not to be suitable for production of fodder workshop, and cost also cannot be imagined; 3) precooling of normal temperature material can only be applicable to, high temperature and anti-low temperature requirement of going mouldy in production of fodder can not be met; 4) be subject to service life the impact of seal larger, its structure too complex, coordinates between movement parts to require highly, and part easily weares and teares, corrosion failure, safeguards inconvenience, needs often lubricated guarantee motion and sealing; 5) can not reclaim waste vapour latent heat, cause the waste of energy consumption.
