METHOD AND SYSTEM OF EQUIPMENT FOR PROCESSING FERTILIZER, IN PARTICULAR POULTRY

The present invention relates to a method and system of equipment for processing manure, in particular processing cattle, pigs, poultry, and unborn manure of the aforementioned animal species in solid and liquid form (slurry) into compost.

Composting is understood to mean: the process in which one or more organic waste materials are broken down and converted into such a stable end product with the aid of micro-organisms that only slow degradation of humous compounds takes place therein.

The accumulation of manure is a major problem. The removal or processing of this manure is very expensive and often even more expensive than keeping the animals themselves.

An object of the present invention is to provide a method which solves the above problem.

According to a first aspect of the present invention there is provided a method for processing manure, in particular poultry manure, into compost, comprising the following steps: - periodically removing wet manure from an animal accommodation, for instance a poultry house, and - allowing the manure to dry outside predetermined conditions under predetermined conditions.

Since wet chicken manure is removed from the chicken houses in the present invention before being dried, the problem of ammonia emissions, stable climate and possible contamination is considerably reduced compared to houses in which wet manure is also dried. Furthermore, the present invention offers the following advantages: - substantially no investments for drying in the stable (belt drying and feed composition); ü1 0 1 0 4 4 1 2 - better climate means less disease and less medication (assumption); - lower feed consumption than in barn with belt drying due to higher barn temperature (24 ^ 0) - per 5 ° C there is a need to provide 1.5 grams / animal / day of extra feed at a cost of fl. 40 , - / 100 kg of feed; - essentially no uncertainty as to the result related to the season.

Preferably, the wet manure is transported to a manure processing space which comprises - one or more composting spaces, and - manure transport means.

The present invention will be further elucidated with reference to the accompanying description, examples, figures, and tables.

Figure 1 shows a flow chart of a system 5 of equipment according to the present invention.

Figure 2 shows a schematic view of a composting tunnel according to the present invention.

Figure 3 shows a flow chart of the production process of the present invention.

10 1. Method 1.1 Composting (see figure 1, table 6 and table 7)

The supplied solid manure is stored in a trench silo (SI); the supplied slurry is stored in a weighing tank with stirrer (01); the screened structure improver is stored in a trench silo (S7); the fresh structure improver supplied is stored in a trench silo (S2).

20 The mixer (03) is filled by means of a shovel (A) with a certain amount of solid manure from the trench silo (SI), a certain amount of sieved texture improver from trench silo (S7) and fresh texture improver (wood chips, straw, wood fiber, hemp , 25 plastic molds) from slotted silo (S2), where necessary in addition. Also, a certain amount of slurry from a tank (01) and a certain amount of ammonium sulfate solution from a tank (04) are added. The mixing ratio depends on the structure, the C / N-30 ratio and the dry matter content of the products to be processed.

The mixture is then deposited from the mixer (03) by means of a transport screw (05) on a conveyor belt (06), after which it falls on a mobile conveyor belt (08) above the spreader (09). An agent for improving the composting process is optionally added to the mixture on this conveyor belt above the spreader (09). This conveyor belt (08) is movable in the sun and it fills the spreader (09) at the correct level in order to provide a good distribution of the mixture in the spreader (09). This level is achieved by counter-pressure of the mixture using a counterweight (kg). From this belt (08) the mixture falls on the bottom chain of the spreader (09) with rotating rollers. The mixture is conveyed through the scraper floor into the spreader (09), after which it is loosened by the rollers. The cloth behind the spreader (09) 10 ensures its flexibility for a smooth flow of the mixture (no accumulation). The mixture goes via conveyor belts (06) and (10) to a walker (11) (mobile conveyor belt).

The mixture is then evenly distributed over a maximum width of 5 meters (width of the tunnels) through a dividing disc (12) in one of the composting tunnels (T1-T5). The distribution disc (12) (a profiled round disc, whose rotation speed, direction of rotation and the length and position of the 20 pins is adjustable) is located at the end of the belt (11), which is in and out of the tunnels (T1- T5) slides. The mixture is composted under computerized conditions (computer controlled). After the mixture has been sufficiently composted, it is removed from tunnels with a shovel (B) and taken to a trench silo (S3-S6) for temporary storage.

1.2 Dry powder

The composted mixture (a mixture of 30 manure and structure improver with a dry matter content between 60 and 70%) is removed from a trench silo (S3-S6) with a shovel (B) and deposited in a bunker (13). From this bunker, the composted mixture goes via conveyor screws (14) and an elevator (15) to a drum sieve (16). The structure improver is separated from the composted manure and falls into a trench silo (S7). The composted manure is fed through an elevator (19), conveyor belts (18), a redler (20) and a wall pepper 0 1 0 4 4 1 5 (21) with a distribution disc (22) in the drying bunker (23). brought before drying. The distribution disc ensures distribution over a maximum width of 2.5 m (width of the drying bunker). After drying, the dried composted manure passes through a conveyor belt in the drying bunker (23) to a sieve (25), which sieves the remaining structure improver. Then the sieved composted manure goes via an elevator (19) and a redler (20) to an industrial truck (eg a 10 tractor with tipper), which is loaded with a load bellows (26) dust-free (possibly to the press shop) .

1.3 Nadrocrlna granules

The sieved composted manure (powder) can be pressed into granules. These granules are dumped in a bunker (28) and go through a conveyor screw (29) and an elevator (30) to a belt dryer (31) where the granules are dried. After drying, the grains are dust-free for delivery (possibly for bagging) via a redler (32), an elevator (33), a redler (32) and a loading bellows (34).

1.4 Airflow

Fresh air is sucked through the heat exchanger (35) through a fan (36). Heat transfer takes place in the heat exchanger (35), as a result of which the air flow (LI) is heated up. This airflow (LI) is transported by the fan (36) via an air duct and air valve (37) to the belt dryers (31), the drying bunker (23) and the 30 tunnels (T1-T5).

The airflow (L2) from the hopper (23) passes through an air valve (38) and then through a filter (39), where the airflow is cleared of dust. The airflow (L3) from the belt dryers passes through an air valve (38) and is combined with the airflow (L2). Then this mixed airflow (L2-L3) is "presented" to the composting tunnels (T1-T5) through an air valve (41). The composting tunnels (T1-T5) are P1 0 1 044 1 6 each equipped with a fan (45) for aeration of the mixture in the tunnels with an air flow (LI or L2-L3) through perforated air channels (46) in the floor of the tunnels (T1-T5). The composting tunnels 5 (T1-T5) each have an outlet (47) through which the airflow (L4) ends up on an air duct. The remainder of the airflow (L2-L3) not absorbed by the tunnels passes through a pressure relief valve (40) and is combined with the airflow (L4). The mixed air-10 stream (L2-L3-L4), which contains the ammonia, is drawn in by a fan (48) and then through an air duct through the heat exchanger (35), the chemical scrubber (49) and the cooling block ( 50) transported to the bio beds (Bl-B12).

In the heat exchanger (35) an exchange of heat takes place between the air flow from the tunnels (L2-L3-L4) and the supplied fresh air (LI).

1.5 Water flow 20

Washing water (Wl)

Wash water is a solution of tap water (55) and sulfuric acid in the chemical scrubber (49). The mixed air stream (L2-L3-L4) is cleaned in the chemical scrubber (49). The sulfuric acid binds to the ammonia from the air stream (L2-L3-L4), creating ammonium sulfate. This changes the acidity and the specific weight of the washing water.

The acidity of the washing water is maintained by pH measurement (54) and acid dosage (56). Depending on a preset blowdown (57) (change of washing water), the specific weight and thus the quality of the washing water is maintained. The washing water is transported via the washing water control (57) via a pipe to the tank with ammonium sulphate solution (04). In order to have a large buffer of this washing water, with limited fluctuations in the composition, a buffer tank of washing water (58) is connected to the supply of washing water in the chemical scrubber (49).

Condensation water (W2) 5 Condensation water is created when warm airflow (L2-L3-L4) with a high relative humidity passes through a cooling block (50), causing the water vapor to condense.

This water is collected and flows to a lower positioned tank (59).

10

Leachate water (W3)

Leachate water is created because relatively warm airflow (L2-L3-L4) with a high relative humidity cools in the biofilters (B1-B12), causing the water vapor to condense. This water is collected and flows to the lower positioned tank (59).

Condensate and leachate water (W2-3)

This is a mixture of condensation and leachate water, which is made suitable for cooling water by means of addition and aeration. The water from the tank (59) is pumped by means of a pump (60) to the tanks (62) for purification. During pumping, a biological purification agent is added to the tanks (62) by means of a metering device (61). Here aeration of the water takes place by means of a blower (69). The water remains there for 24 hours, after which it is used as cooling water. It is transported by means of a pump (68) to the hopper of the cooling tower (64) to replenish the cooling water supply due to evaporation by cooling tower.

Rainwater (W4)

Rainwater is collected and passes through a 35 bend (66) to a tank (67).

Tap water (W5) P1 0 1044 1 8

When the water in the tank (67) falls below a certain level, the stock is replenished with tap water (W5) to a minimum stock for, for example, 24 hours.

5

Rain and tap water (W4-5)

This is a mixture of rain and tap water, which is made suitable for cooling water by adding and aeration. When the water in the tank (62) falls below a certain level, the stock is replenished with rain water (W4-5) by means of a pump (63).

Cooling water (W6) 15 This is biologically purified condensate and percolate water (W3-4) and / or the mixture of rain and tap water (W4-5).

Shovel A Means of transport for solid manure and the structure improver to mixer

Shovel B Transport of the compressed mixture from the tunnel to the trench silo 1010441 14 3. Production process (see figure 3) 3.1 Supply

Fresh poultry manure from laying hens (A) 5 (25-30% DS) is supplied (stream 1). A structure improver (B) (60-70% DS) is also supplied (stream 2).

3.2 Mixing 10

Fresh poultry manure from laying hens (A) with a dry matter content of 25-30% (stream 3), structure improver (B) with a dry matter content of 60-70% (stream 4), is sieved in a predetermined ratio. structure improver (J) with a dry matter content of 60-70% (stream 12), composted mixture with a dry matter content of 60-70% and the solution of ammonium sulfate with a specific gravity of 1.1 (stream 5) into the mixer (E). The mixing ratio of the mixture 20 (38-42% DS) is manure: structure improver: composted material: ammonium sulfate solution = 1: 2: 0.1. The ratio depends on the structure, C / N ratio and the dry matter content of the products to be processed.

25 3.3 Filling

Before the mixture (38-42% DS) (stream 6) is placed in a tunnel (G), it can first be sprayed (stream 7) with biological products to improve the composting process. Thereafter, the mixture (stream 7) is loosened (F) for proper product distribution in the tunnel and better oxygen flow to subsequently obtain an aerobic bacteriological action (oxygen consumption). This mixture is then transported to a tunnel (stream 8) and distributed (G). The tunnel is now filled with 400 m3 of mixture with a filling height of 3.5 to 4.0 m. The control program for this »1010441 15 tunnel is in phase 1.1" filling "(settings see appendix).

3.4 Composterinasoroces

If the tunnel is completely filled with a mixture (38-42% DS), the control program is put in phase 1.2 "heating up", after which the mixture heats up from 20 ° C to 70 ° C in 8 hours (set time). When the temperature has reached 70 ° C and the set time has elapsed, the control program switches to phase 2.1 10 "pasteurisation" where the mixture is then kept at 70eC for 8 hours (set time). When this time has elapsed, the control program switches to phase 3.1 "cooling for conditioning" where the mixture is cooled back down from 70eC to 65eC for 12 hours (set 15 time).

When the temperature of 65 ° C is reached, the control program switches to phase 4.1 "conditioning". At this stage, the starting temperature of the mixture is 65 ° C. This temperature is lowered from 65eC to 61eC over a period of 20 124 hours. In this phase, the supply air (mixture of outside and tunnel air) is set to 55 ° C. The supply air is gradually increased over a period of 124 hours from 55 ° C to 55.5 ° C. In this phase oxygen minimum (14%) and maximum (22%) are set to possibly react the air valve, which ensures that sufficient oxygen is supplied. Aerobic microorganisms use oxygen to break down organic matter. In order to supply this oxygen and to keep the temperature of the mixture as homogeneous as possible, an air flow of 6000 m3 / hour is set, which is maintained by a fan (continuously adjustable). An air flow of 1000-2000 m3 / hour with a temperature of 65eC leaves the tunnel. The air flow (outside air), with a temperature of 16eC and a 35% RH of 70%, entering the tunnel will be relative to the air flow (return air), with a temperature of 65 eC and an RH of 100%, which leaves the tunnel contain little water; so water evaporation takes place. Over 1 0 1044 1 16 over a period of 124 hours, 50,000 liters of water are evaporated (average 400 liters / hour).

When the set time of 124 hours has elapsed and the set end temperature of 61 ° C has been reached, the control program switches to phase 5.1 "cooling before emptying". At this stage, the mixture is cooled from 61 ° C to 20 ° C in a preset time (16 hours). Air is used, which is heated by a heat exchanger. This air has a great cooling and drying effect. During this cooling, another 5000 liters of water are evaporated (an average of 300 liters / hour). When the set time of 16 hours has elapsed and the set end temperature of 20 ° C has been reached, the control program switches to phase 5.2 15 "ready for emptying".

3.5 Lecren

The control program for this tunnel is in phase 5.2 "ready for emptying". The composted mixture is driven to a post-processing storage (H) (stream 9) by means of a shovel. After composting, the mixture has obtained a dry matter content of 60-70%.

3.6 Sieving The composted mixture with a dry matter content of 60-70% (composted manure and structure improver) is then sieved (I), separating the composted manure from the structure improver. The structure improver goes to a storage (J) (stream 11) for subsequent reuse.

3.7 After-drying powder

The composted manure (powder) with a dry matter content of 60-70% is placed in a drying bunker (K) (stream 13) and then dried for 16 hours. During this drying process, an air stream heated up by the heat exchanger of »1 0 1044 1 17 10,000-25,000 m3 / hour with a temperature of 55 ° C and an RH of 5% is blown through the composted manure, resulting in water is evaporated instead. The composted manure is dried to a dry matter content between 70-5 and 80%. After drying, the powder is sieved a second time (L) (stream 14), the remaining structure improver being sieved and transported (stream 15) to a storage (J) for reuse. The material is ready for delivery in bulk (stream 16), or to be pressed into granules (stream 17).

3.8 Post-drying granules

Granules (pressed composted manure) with a dry matter content of 75-85% are supplied (stream 20), which are dried for 16 hours by means of a belt dryer (P). During this drying process, an air flow heated by the heat exchanger of 10,000-25,000 m3 / hour with a temperature of 55 ° C and an RH of 5% is blown through the granules, whereby water is evaporated. The granules are dried to a dry matter content of at least 90%. The dried granules are then ready for delivery in bulk (stream 21) or for packaging (stream 22).

Both compost obtained by the method according to the present invention and the previous fresh manure were examined at the Company Laboratory for Soil and Crop Research in Oosterbeek. The results of this study are shown in the tables below.
