Definitions
- PROTEIN FEEDSTOCK COMPOSITIONS AND METHODS AND APPARATUS FOR THE PRODUCTION THEREOF
- This invention relates to protein feedstock, compositions and methods and apparatus for the production thereof.
- This invention has particular but not exclusive application to fish by-product protein feedstock, compositions and methods and apparatus for the production thereof, and for illustrative purposes reference will be made to such application. However, it is to be understood that this invention could be used in other applications, such as other animal by-product protein feedstock, compositions and methods and apparatus for the production thereof.
- the use of fish processing waste and bycatch as a manufacturing feedstock for fertilizer production is acknowledged as a desirable way of putting such wastes to use, due to the well known properties of fish wastes as a source of nitrogen, phosphorous, potassium and trace minerals required by plants for healthy growth.
- fertilizer compositions currently produced are the so called fish emulsions, where aqueous slurries of ground fish waste are allowed to decompose, and a liquid suspension harvested therefrom and packaged or distributed in bulk for fertilizer use.
- Other processes include the production of fish meal fertilizer compositions.
- this invention in one aspect resides broadly in a method for production of protein feedstock comprising:- comminuting fishery waste; adjusting the pH of said comminuted fishery waste to an acid pH selected to encourage microbial digestion; microbially digesting said acidified fish waste at a temperature between 25°C and 38°C; screening said digestate to yield a substantially liquid phase, and aging said liquid phase.
- the fishery waste may comprise one or more of filleting wastes (fish frames), bycatch or waste whole fish, Crustacea or the like.
- the fish waste may be comminuted to an average particle size of less than 25 mm, and is preferably comminuted to an average particle size of from 6mm to 25 mm.
- the comminution may be done by any suitable means such as by mincing, grinding or chopping, preferably such that the temperature of the waste does not exceed 35°C, and especially about 20°C, either in the bulk matrix or at the shearing point.
- Most fishery waste streams have a moisture content of from 50 to 99 wt % and the water content of the comminuted fish waste is preferably adjusted to this range.
- the pH of the comminuted fishery waste is preferably adjusted to the selected range by means of mineral or organic acid addition.
- the pH may be adjusted by the addition of strong mineral acids such as hydrochloric, sulphuric or nitric acids.
- strong mineral acids such as hydrochloric, sulphuric or nitric acids.
- organic acids such as formic acid.
- the pH being selected to encourage the growth of the digesting microorganism will at least in part be determined by the range of pH tolerance of the selected microorganism.
- the microorganism is selected from those which grow best in the acid range for reasons described hereinafter.
- the preferred range of pH is 4.5 to 5.0.
- the digestion is preferably performed in a closed digester, and accordingly the digestion is preferably performed by obligate or facultative anaerobes.
- the digestion ⁇ iay be initiated and progressed by the addition of a culture of microorganisms such as those commonly used for the production of cultured milk products.
- the microorganism may be selected from the yoghurt-forming microorganisms such as Lactobacilli spp. such as Lactobacillus acidophilus.
- the digestion may be performed by one or more of Bacillus spp. such as B. subtilis or B. licheniformis, Pseudomonas spp. such as P. fluorescens or P. aeruginosa, or Escherichia hermanii.
- the digestion may be assisted microorganisms native to the fishery waste and amenable to the conditions of processing. Accordingly, the digestion may be done with or without presterilization of the mixture.
- the digestion is performed in the specified temperature range, the temperature being maintained by cooling or the digestion accelerated by heating as the case may require.
- the temperature is preferably in the range of 25°C to 38 C C, for the purpose of maintaining high activity of the acidic anaerobes relied upon for the digestion whilst suppressing the activity of ther ophilic, often sulphur-reducing (hydrogen sulphide producing), microorganisms.
- the digester may be provided with such additives as may be deemed appropriate to encourage the digestion of the fishery waste by the microorganisms.
- additives for example, trace minerals, enzymes and cofactors therefor, and vitamins may be added in accordance with the principles and knowledge of the industrial fermentation art. It has been particularly observed by the inventor that the addition of from 0.01 to 0.2 wt % ascorbic acid to the digester has a beneficial effect on the native microflora of fishery wastes. It has also been surprisingly noted that the acidic, anaerobic flora preferred for the processes of the present invention have a tolerance for certain antimicrobial compounds and compositions which may be advantageously used to reduce competition from less desirable microorganisms.
- this invention resides in a method for production of protein feedstock comprising anaerobically digesting an aqueous slurry of fishery waste at a temperature between 25°C and 38°C in the presence of an antimicrobial compound selected to permit survival of acidophilic anaerobes in said slurry.
- the antimicrobial compound is a compound having a broad spectrum of cytotoxicity to microorganisms such as yeast, mould and bacteria, whilst being well tolerated by the desirable acidophile anaerobes of the present invention. It has determined that sorbic acid and sorbates, used in the range of 0.01 to 0.2 wt % measured as sorbic acid, encourages the activity of the native acidophiles of fishery wastes.
- the digestion is run to conclusion which may be determined by any known objective measure such as the digester temperature tending to ambient temperature without control. In general, the process of digestion is concluded in about four to seven days at 25 C C to 38°C respectively.
- the digestate is preferably screened to less than 1.5mm to provide a liquid protein feedstock fraction having some suspended particulates and emulsified components, and a compostable solids fraction. It has been determined that after digestion has concluded, the metabolites of digestion are still reactive. Insofar as these metabolites are malodorous, although not to the extent of the ammoniacal and sulphidic prior art fermentates, it has been found that to age the digestate at ambient temperatures for approximately two weeks is to substantially reduce the odour associated with the protein feedstock product. Preferably, the proliferation of opportunistic microorganisms during the aging process is reduced by the addition of a preservative such as potassium sorbate.
- a preservative such as potassium sorbate.
- a typical range of additions and process conditions for digestion of fisheries waste may include pumping comminuted fisheries waste into a closed vessel with addition of a culture of Lactobacillus acidophilus.
- the Lactobacillus culture may be prepared by growing ( for 3 to 7 days at 25 degrees C) lOg of freeze dried bacteria in 20kg molasses and 20 litres water, producing a grown culture suitable for treating 1000 litres of fisheries waste.
- the pH of the mixture will generally require reduction with typically 2 litres of technical nitric acid for each 1000 litres of fisheries waste. Again preferably allowing an approximate three hour rest phase, there may be added addition nutrients for the bacterial culture and to modify the minerals balance of the final product. For example, there may be added cofactors such as ascorbic acid, typically at 1 kg per 1000 litres fishery waste.
- Other additives may comprise: 20g - 2kg phosphorous acid 200ml - 4Lt phosphoric acid 0 -3Lt technical sulphuric acid 26g - 1kg boric acid 6 - 200g sodium molybdate
- the pH may be checked to ensure appropriately acid conditions for the selected digesting microoganism, typically 4.5 to 5.0 for the preferred L.acidophilus.
- the digestion as observed is carried out for an appropriate time determined by completion of digestion.
- the pH may be adjusted up by the addition of a base such as calcium carbonate or down by addition of a mineral or organic acid.
- the digestate is preferably lowered in pH to the bottom of the facultative range with mineral or organic acid such as formic acid, prior to pumping to a first screening means to remove solids of for example greater than 3mm.
- the screened material may then be aged in accordance with the present invention.
- the digestate may be aged for up to three months, preferably with periodic pump recirculation to encourage homogenous aging. Aging is preferably done in a stainless steel tank.
- the recirculation may be done daily, and the temperature preferably maintained in the range 25°C to 38°C and the pH in the facultative range.
- the aged digestate may be further screened, typically down to 1.5mm maximum particle size, and pumped into a secondary aging tank of plastic or other inert material. Typically the secondary aging may be for about 2 months.
- an inhibitor such as sorbic acid or sorbate salts.
- Such inhibitors may be added at a rate of 200g per lOOOLt of digestate.
- the pH may be lowered to be strongly acidic, such as to 3.3 by addition of formic acid or the like. Again the temperature is typically maintained in the range 25°C to 38°C.
- the digestate protein feedstock produced by the foregoing methods may find use in any application where a digested animal protein source may be used, such as fertilizer compositions, stock feed supplements and aquaculture nutrition.
- this invention resides in a fertilizer composition
- a fertilizer composition including an aged, liquid protein feedstock produced from fishery waste, said fishery waste being comminuted at a temperature of preferably not more than 35 C C, acidified to a facultative pH, microbially digested at a temperature between 25°C and 38 C C and screened to yield a substantially liquid phase prior to aging.
- the fertilizer compositions of the present invention are preferably in the form of relatively stable emulsions and/or suspensions in a continuous phase comprised in the majority of the protein feedstock of the present invention.
- the composition may comprise trace elements, antioxidants, preservatives and the like, in stable solution, suspension or emulsion in the protein feedstock, in accordance with the additive's phase and solubility.
- oily phase additives may be emulsified in the composition by the use of a suitable surfactant.
- the surfactant is selected from the nonionic surfactants to avoid flocculation or precipitation by charge effects from what is a complex mixture of components the result of digestion of fishery waste.
- the compositions may be boosted in nutrients if desired by the addition of mineral additives dispersible in one or the other of the phases of the composition.
- the digested and aged protein feedstock will generally by its nature include a proportion of emulsified fish oil
- a physiologically compatible oil such as fish oil or vegetable oil.
- the oily addition is a physiologically compatible vegetable oil.
- the added oil is precharged with oil compatible additives intended for the compositions, and may be premixed with the surfactant necessary to emulsify the oil in the composition.
- compositions of the present invention In the process of developing the embodiments of the compositions of the present invention, it has been determined that particular master compositions comprising the oil phase and emulsifier are particularly advantageous. These compositions are those having reduced oil gum, the oil gum being a consequence of the multiple unsaturation in the fatty acid chains constituting the triglyceride oil. It has been surprisingly determined that a compatible surfactant when mixed with a vegetable oil containing gum will effect the precipitation of the gum from the oil.
- this invention resides broadly in a method for producing oil master compositions for use in oil-in-water emulsion fertilizer compositions and comprising: - treating a vegetable oil with surfactant sufficient to emulsify said oil in an aqueous phase; removing precipitated gum from said oil, and adding an antioxidant to said treated oil.
- the vegetable oil is preferably a mono or polyunsaturated vegetable oil.
- the vegetable oil may be selected from food or technical grade vegetable oils such as canola, safflower, mustard seed, or peanut oils.
- the surfactant is preferably a nonionic surfactant miscible with the vegetable oil or at least soluble therein to the extent necessary to provided a composition with the oil which is emulsifiable in an aqueous phase.
- the surfactant may be selected from the vegetable oil- soluble nonionic surfactants such as alkoxylated hydroxy- functional triglyceride oils such as castor oil.
- the antioxidant may be selected from any of the known antioxidants for unsaturated fats, and is preferably selected from antioxidants approved for food use. It is particularly preferred to use antioxidants having the potential for uptake by plants as cofactors such as free radical scavenging vitamins or derivatives thereof such as dl- ⁇ -tocopherol acetate.
- the master composition may include other oil soluble additives such as other vitamins.
- the digestate compositions of the present invention have also proved to be unexpectedly useful in aquaculture, particularly in fish farming, as food supplement.
- the compositions may be utilized at a delivery rate of 8 ml per day per kilogram live weight of fish at typical liveweight loadings of aquaculture ponds.
- the nutrient loading may be maintained at 1 part by volume of composition per 100 to 400 litres of pond water.
- the digestate compositions may be utilized in lieu of or in addition to the kelp supplements commonly fed to stock to prevent or treat selenium and iodine deficiencies, in horses, cattle and other grazing animals. It has been determined that the deficiencies addressed by kelp supplements are also at least in part addressed by the present compositions.
- the compositions may be utilized at levels of 15 to 20 ml per beast per day for large animals, with less being required for smaller beasts such as pigs, which may thrive on about 10 ml per day.
- compositions in accordance with the present invention may be achieved by direct administration to the beast or addition to drinking water, wherein the compositions are wholly dispersible. It has been found that the compositions are advantageously administered for alternate weeks of seven days.
- the comminution of the waste prior to digestion not result in local of bulk heating above 35°C. If the temperature is raised above 35°C, the fishery waste tends to cook, affecting the quality of the final product. Apparatus for comminuting fishery waste by grinding or mincing tend to heat the waste quite considerably.
- this invention resides in comminuter apparatus including:- a housing having an inlet opening including a shearing edge; a shearing blade rotatable in said housing having a leading edge extending outward from a hub portion of the blade having an outer edge portion curving in the direction of rotation and adapted to cooperate with said shearing edge, and a plurality of mincing blades mounted for co-rotation with said shearing blade.
- the housing may include an internal space of any shape representing a solid of rotation, although it is preferred that the space be substantially cylindrical, the cylindrical surface being defined by an inner housing wall.
- an outlet may be provided in the form of a perforate portion of the inner housing wall in communication with a space between the inner housing wall and an outer housing wall.
- the inlet may comprise an aperture in an end to the housing defined in part by the shearing edge disposed along a chord to a substantially circular end of the housing, the edge comprising the corresponding shearing edge adapted to cooperate with the shearing blade.
- the shearing edge may be disposed substantially radially of said housing end.
- the shearing blade may extend across a selected span of the inlet. However, it is preferred that the shearing blade extend such that it sweeps substantially all of the inlet and that the shearing blade sweep the length of the corresponding edge of the inlet.
- the shearing blade edge may curve in a substantially epicycloid shape in the direction of rotation from the hub of the blade. Alternatively, the curvature may have a smooth transition from curving backwards relative to the direction of rotation from the hub portion, preferably for 30-50 % of the blade radius, through a neutral point to an outer tip swept forwards in the direction of rotation.
- the blade For processing fishery waste, the blade may be set such that a specified clearance is maintained between the blade edge and the shearing edge. For example, experimentation has established that for prawn processing waste, a clearance of about 6 mm produces an particle size spread of the comminuted product suitable for the production of the protein feedstocks of the present invention.
- the blade may be one of a plurality of such blades distributed evenly about the axis of rotation of a rotor mounted within the housing.
- the apparatus may be provided with four such blades although it is envisaged that an odd number or other number of blades may be selected.
- the apparatus is provided with four such blades mounted in orthogonal sets of two blades each, with adjacent blades axially staggered such that a clearance of about 6 mm is maintained between the shearing planes of the respective sets. It has been found that this configuration promotes an advantageous distribution of particle size of selected fishery wastes such as prawn processing wastes.
- the mashing blades may, for processing the majority of fishery wastes, comprise a plurality of mashing blades which are preferably mounted on a common rotor with the shearing blade or blades.
- the mashing blades are mounted in sets with the sets distributed about the rotary axis and extending from the shearing blade or blades to the end of the housing remote from the inlet.
- the rotor may be driven by any suitable means and is preferably driven by an electric motor.
- This invention further relates to antinematodal soil treatment methods and compositions therefor derived from the foregoing compositions.
- Nematodes are a serious soil pest of commercial crops.
- this invention in one aspect resides broadly in an antinematodal soil treatment method comprising applying to the soil a nematodicidally effective amount of a protein composition produced by: comminuting fishery waste; adjusting the pH of said comminuted fishery waste to an acid pH selected to be facultative for digestion microbes; microbially digesting said acidified fish waste at a temperature between 25°C and 38°C; screening said digestate to yield a substantially liquid phase, and aging said liquid phase.
- the proteinaceous material may be used directly or distributed in irrigation water.
- the proteinaceous material is applied at a rate of at least 60 L/ha to provide a nematodicidal effect.
- the active culture may comprise the dormant culture present in the aged protein product itself or may be added to the emulsifiable composition of oil phase and protein product. In either case it is preferred that the composition include biologically active lactobacillus acidophilus at the time of application to the soil. It has been found that effective protein product application rates down to below 40 L/ha are nematodicidally effective using the aforementioned emulsifiable oil/protein/bacteria mixtures.
- oily phase additives may be emulsified in the composition by the use of a suitable surfactant.
- the surfactant is selected from the nonionic surfactants to avoid flocculation or precipitation by charge effects from what is a complex mixture of components the result of digestion of fishery waste.
- the added oil is precharged with oil compatible additives intended for the compositions, and may be premixed with the surfactant necessary to emulsify the oil in the composition.
- oil compatible additives intended for the compositions
- surfactant necessary to emulsify the oil in the composition.
- the method of use of the aforementioned preferred compositions may comprise irrigation spraying or direct application to the ground, application of the compositions directly followed by watering in or any other method capable of delivering the composition to the soil horizon containing the nematode infestation.
- the composition is used at a protein feedstock loading of at least 30 L/ha and preferably at least 40 L/ha.
- Preferably the mixture is applied by entrainment with irrigation water applied directly to the soil.
- Protein feedstock used directly is used at least 60 L/ha.
- the soil is treated at least twice to substantially eliminate nematode infestation.
- the soil may be rested after a first treatment prior tilling and/or fertilizer application ready for planting, followed by a second treatment, resting then, planting.
- FIG. 1 is a side view of a shearing blade assembly for comminuter apparatus in accordance with the present invention
- FIG. 2 is side view of the assembly of FIG. 1
- FIG. 3 is a section through comminuter apparatus in accordance with the present invention.
- comminuter apparatus 10 including an outer substantially cylindrical housing 11 closed at one end by an end plate 12. Mounted within the outer housing 11 is a cylindrical inner housing 13 defining a rotor chamber 14. An annular space 15 between the outer 11 and inner 13 housings communicates with an outlet (not shown)from the apparatus 10.
- Closing the end of the inner 13 and outer 11 housings is a closure assembly 16 secured by a bolting ring 17 to a corresponding bolting flange 20 formed on the periphery of the outer housing 11.
- the closure assembly 16 incorporates a substantially semicircular-section inlet chute 21 bounded by a curved wall portion 22 abutting a portion of the inner housing 13 and a flat wall portion 23 disposed diametrically across the end of the inner housing 13.
- the flat wall portion 23 is provided with a fixed shearing edge 24 extending into the inner housing 13 and being disposed substantially along a radius of the inner housing 13.
- the portion of the closure assembly 16 not occupied by the inlet chute 21 is closed by closure portion 25.
- a rotor assembly 26 comprising a driven shaft 27 penetrating the end plate 12 and having mounted thereon a plurality of mincing blade assemblies 30 arranged in alternating orthogonal pairs.
- the shaft 27 mounts two pairs of shearing blades 31 arranged orthogonally on the shaft 27 and secured by a nut 32.
- the closest pair of shearing blades 31 to the shearing edge 24 is mounted such that a clearance 33 of about 6 mm is maintained therebetween.
- the shearing blade edges 34 extend outward from the region of the shaft 27 to tips 35, with the outer halves of the blade edges 34 being curved in the direction of rotation of the blades 31, and the inner halves being curved from the region of the shaft 27 away from direction of rotation, the two halves describing a smooth curve meeting at a transition point 36.
- the outer halves are swept forwards from the transition point 36 by approximately 17.5° of arc, whereas the inner halves are swept back from the shaft 27 to the transition point 36 by approximately 45° of arc.
- waste material such as fisheries waste may be manually sorted to remove obvious rubbish and may further be sreened by a metal detector to provide automatic shut down of plant before damage is occasioned.
- the fishery waste may be optionally blown with air to remove loose scales.
- the waste may be crushed prior to passing to the mincer.
- the raw or pretreated waste is fed to the apparatus 10 through the chute 21 whereupon it is sheared by the shearing blades 31.
- the clearance 33 provides for control of the particle size of the sheared product whilst the shearing action provides that the sheared product presents an appropriate shaped particle to the mincing blades.
- Effective shearing is maintained by the inner halves of the shearing blade edges 34 urging the material to the neutral point 36 of the blade edges 34 whilst the outer halves act to restrain the centrifugal acceleration of the material to ensure that the majority passes effectively to the mincing blades 30.
- the mincing blades 30 then further comminute the material to the desired particle size before discharging the processed meal to the annular space 15 and thence to an outlet via apertures 37 provided through the inner housing 13.
- the use of the shearing action reduces the initial heat generation common to the prior art apparatus whilst the mincing stage presents a product of physical form consistent with that produced by the prior art apparatus.
- EXAMPLE 1 Protein feedstock A culture aliquot of Lactobacillus acidophilus was grown by the addition of 20 kg molasses to 20 Lt water to form a growth medium, the temperature of which was adjusted to 25°C prior to the addition of a starter culture of the bacteria or lOg of freeze dried bacteria.
- Into a 4000 litre digester was placed fisheries waste processed using the apparatus of FIGS 1 to 3 at 20°C, with progressive addition of 4 aliquots of the grown bacterial culture. After 3 hours stabilization the waste was acidified with 8 Lt technical grade nitric acid, and after a further 3 hours stabilization 4 aliquots of the following additive mixture were slowly added: lkg ascorbic acid
- the pH was checked and adjusted to the range 4.5 to 5.0 by addition of calcium carbonate (1.0 micron) or formic acid as required from batch to batch.
- the digester was then brought up to a temperature of 30°C to initiate active growth by the bacteria.
- the digester was run for 7 days with the temperature being maintained in the region of 30 C C and between 25°C and 38°C. During the digestion, the pH tended to drop and the pH was maintained in the range of 4.5 to 5.0 by calcium carbonate additions.
- the digestate was pumped to a vibratory screen to reduce the maximum particle size to 3mm and the pH was reduced to 4.5 by the addition of formic acid.
- the screened digestate was pumped to a second stainless steel tank, maintained at pH 4.5 to 5.0 and temperature 25 to 38°C and stirred daily by recirculation for 3 months.
- the aged digestate was then further screened by vibratory apparatus to reduce the maximum particle size to 1.5 mm before being pumped to a plastic tank and further aged at between 25°C to 38 C C for two months with recirculation.
- the pH was dropped to 3.3 by the addition of formic acid to inactivate the bacteria and other microorganisms, the preservation of the aged digestate being further promoted by the addition of 200g/1000Lt sorbic acid as potassium sorbate.
- EXAMPLE 3 FERTILIZER COMPOSITION 1 To 3.6 kilograms of boric acid was added 1.5 kilograms of monopotassium phosphate, 112 grams of sodium molybdate, 12 kilograms of potassium sulphate, 5.5 kilograms of magnesium sulphate, 1 kilogram of ascorbic acid and 500 milliliters of surfactant (Teric 9A6) . 500 litres of the protein feedstock of example 1 was added to a paddle mixer and to which the foregoing additives were added with thorough mixing. 15 litres of the oil adjuvant of example 2 was added and the mixture made up to 1000 litres with further protein feedstock of example 1. EXAMPLE 4 - FERTILIZER COMPOSITION 2
- the mixture was mixed to be substantially homogeneous and then transferred to a mixing vacuum oven, where the temperature was increased to between 45-50 c C under vacuum to partially sterilize the composition and reduce the moisture content to a packagable level.
- a 1 hectare plot of farmland having a commercially significant nematode infestation was identified.
- To 40 parts by volume of the protein feedstock of example 1 was added 1 part by volume of the oil adjuvant of example 2, with mixing until an emulsified composition was formed.
- To the mixture was added an active culture of Lpctobacillus acidophilus with mixing. The final mixture was then turbulently dispersed into an irrigation stream and applied to the soil at a net rate of 40 L/ha of protein feedstock.
