Description
A METHOD AND APPARATUS FOR PRODUCING FERTILISER FROM ANIMAL BY-PRODUCT AND/OR FOOD WASTE AND THE
RESULTING FERTILISER PRODUCT
The present invention relates to a method and apparatus for producing fertiliser from animal by-product and/or food waste and the resulting fertiliser product.
During the processing of animals for meat production or otherwise, relatively large amounts of the animal are removed, discarded and not sold onto an end user. Such discarded by-products include bone, blood, wool and feathers for example. This represents a significant waste of the animal resource. There is also a cost involved in storing and disposing of such waste. The same applies to human food waste.
According to a first aspect of the invention there is provided an apparatus for producing fertiliser from animal by-product and/or food waste comprising:
an inlet for receiving raw animal by-product and/or food waste,
a heater operative to heat the animal by-product and/or food waste to a predetermined temperature in the range 50°C to 185°C to form a heated mixture,
a catalyst supply unit operative to supply a catalyst to the heated mixture, an acidification supply unit operative to supply acid to the heated mixture to form an acidified mixture,
a lime mix supply unit operative to supply a lime mix to the acidified mixture to form a pH neutralised mixture,
and a bitter compound supply unit operative to supply bitter compounds to the pH neutralised mixture to form a bitter mixture.
The apparatus may further comprise a pre-breaking unit operative to break the animal by-product down before being heated.
The apparatus may further comprise a granulator operative to granulate the neutralised mixture to form a granulated mixture. The apparatus may further comprise a packaging unit operative to package the granulated mixture.
The catalyst supply unit may be operative to supply a catalyst.
A metal detector may be provided operative to detect any metal content in the raw animal by-product and/or food waste and to generate a corresponding signal that is used to prevent raw animal by-product entering the apparatus if metal content is detected.
According to a second aspect of the invention there is provided a method for producing fertiliser from animal by-product and/or food waste comprising steps of:
receiving raw animal by-product and/or food waste in a vessel,
heating the animal by-product and/or food waste to a predetermined temperature in the range 50°C to 185°C to form a heated mixture, supplying a catalyst to the heated mixture,
supplying acid to the heated mixture to form an acidified mixture, supplying a lime mix to the acidified mixture to form a pH neutralised mixture; and
supplying bitter compounds to the pH neutralised mixture to form a bitter mixture.
According to a third aspect of the invention there is provided fertiliser produced using the apparatus or method of the first and second aspects of the invention.
Other aspects of the present invention may include any combination of the features or limitations referred to herein.
The present invention may be carried into practice in various ways, but embodiments will now be described by way of example only with reference to the accompanying drawings in which:
Figure 1 is a schematic view of an apparatus in accordance with the present invention.
An animal by-product processing plant 1 comprises an inlet 3 which receives raw animal by-product and/or food waste. A metal detector may provided at the inlet 3 to detect any metal in the raw animal by-product and to generate a control signal indicative of any metal content detected. The raw animal by-product and/or food waste is fed, to a pre-breaker 5 which may comprise a crusher for example. The crusher is operative to crush the raw animal by-product and/or food waste into pieces of less than a predetermined size. Sequential refiners may be provided to sequentially break the animal by-product and/or food waste into smaller pieces. These may be provided in processing vessel 7 described below.
The broken down animal by-product and/or food waste is fed into a processing vessel 7 comprising a heater 9. Detectors may be provided at the vessel 7 to detect the weight of the particles. A temperature sensor is also provided to detect the temperature of the particles. The heater 9 is
operative to heat treat the animal by-product and/or food waste at a temperature between 50°C and 185°C for a predetermined time period.
The vessel 7 may further comprise a mixer operative to mix the animal byproduct and/or food waste before, during and/or after heating. A catalyst supply unit 1 1 is provided operative to supply a catalyst to the heated mixture. The catalyst assists with speed of production, and with the release of insoluble minerals.
An acid supply unit 13 is provided operative to deliver, acid to the heated mixture. This dissolves all proteins for the removal of pathogens to form an acidified mixture.
Once the above mixture and additives have been heated and subsequently mixed for the required time, an acidified mixture is produced with any disease in the initial raw animal by-product and/or food waste having been killed. A lime mix supply unit 15 is operative to supply a lime combination to the acidified mixture in order to increase the pH of the mixture. This neutralises the pH to form a neutralised mixture.
The lime mix may comprise a mixture of chalk and lime, or quick lime for example. The lime mix may also comprise additives to alter the properties of the mix, such additives for example comprising selected macro/micro nutrients. The lime mix, and/or the additives, can be varied as required to deliver the required fertiliser properties. The lime mix causes an exothermic reaction. This serves to at least partially dry the acidified animal by-product. The lime mix comprises a lime matrix which produces a granular slow release natural organic fertiliser (provided organic animal
by-product is used initially), with no water course pollution, and with the correct pH levels.
A bitter compound supply unit 17 then supplies at least one bitter compound(s) to the neutralised mixture to deter any living organisms other than plants from ingesting the fertiliser, help balance essential nutrients, and assist with mineral uptake by the plants.
The bitter mixture may then be transferred to a pellet press or granulator 19 operative to press the dried mixture into pellets or granules of a desired size. As an example only, 5 to 6mm pellets or granules are envisaged. The pellets or granules of the desired pH and nutritional value are fed into a packaging unit 21 which conveniently may comprise a bagging machine operative to weigh and bag the pellets or granules.
A further additive that can be added initially, or as part of the lime mixture. This assists the release of plant friendly nitrogen during use of the fertiliser, and also provides the fertiliser with a bitter taste that deters animals from eating the fertiliser.
The mixture and additive proportions above are examples only, other properties being envisaged.
The above described supply units, vessel, heater, and packaging unit, may all be linked to, and controlled by, a suitable electronic controller which may comprise a computer processor or processors. Such a controller may be provided with a display to display parameters of the apparatus 1 to an operator, and may be provided with an interface to enable to the operator to control each of the individual components. Some or all of the plant operation may be controlled automatically by the electronic controller.
The electronic controller may receive various control signals from each component indicative of the operational parameters of each component, and from sensors provided at various parts of the plant. Such sensors may produce output signals indicative of such parameters as weight of by- product being processed, temperature, pressure, valve gate condition, pump activation and speed, and throughput both through each component and through the plant overall.
On/off detection may be provided at some or all components, and an automatic shut-down algorithm may be provided. The above described plant is for use with any desired type of animal by-product and/or food waste.
The fertiliser product so produced has advantageous properties as described, and is produced from animal by-product and/or food waste that would otherwise be wasted. It will be appreciated that further additives of any suitable ingredient can be added to the mixture to adjust the mineral or nutritional content of the solid slurry particles to suit a particular use or location of use. Thus the additives can be controlled to alter the macro/micro nutrient bases of the solid slurry particles to suit different soil or ground conditions for example, or to provide optimum nutrition for a particular type of crop.
