Description

Technical Field

[0001] This invention relates to materials for processing eggs (egg liquid) and methods for processing eggs. Background Technology

[0002] For example, in Japan, once a highly pathogenic avian influenza outbreak occurs, the prefectural governor will issue a culling order, and chickens will be culled at chicken farms. After being culled, the chickens are sterilized with lime, packed into flexible container bags (hereinafter referred to as "flexible bags"), and buried in the ground.

[0003] In situations where a large number of chickens are raised in a chicken farm, culling a large number of chickens at once would overwhelm the sterilization and burial processes, potentially causing the chicken carcasses to decompose. Therefore, from a hygiene perspective, a limit has been set on the number of chickens that can be culled at one time.

[0004] However, if the number of chickens to be culled is large, the chickens waiting to be culled will lay eggs every day, producing a large number of eggs. These eggs, like the chickens, will also be disposed of (discarded) and placed in flexible bags for landfill.

[0005] However, if eggs are placed in flexible bags, the shells may break, causing the egg white and yolk to accumulate inside. Therefore, when disposing of eggs, to prevent leakage from the flexible bags, they should only be filled to less than half their capacity (1000L) (400-500L). Furthermore, because the contents of the flexible bags filled with eggs are liquid, they cannot be double-stacked during transport and become unstable during landfilling.

[0006] Therefore, for example, one could consider using a wastewater absorption and treatment pack as described in Patent Document 1, or a water-absorbing sheet as described in Patent Document 2, to absorb egg liquid produced from cracked eggs. Specifically, the wastewater absorption and treatment pack in Patent Document 1 utilizes the action of a water-absorbing polymer encapsulated within the pack to absorb and treat residual sauce on cups, leftover miso soup, and other domestic wastewater. The water-absorbing sheet in Patent Document 2 utilizes the action of a water-absorbing polymer contained in its absorbent layer to absorb moisture seeping from meat, fish, vegetables, etc.

[0010] Patent Document 2: Japanese Patent Application Publication No. 2017-47341 Summary of the Invention

[0011] The problem that the invention aims to solve

[0012] However, experimental studies conducted by the inventors have shown that egg liquid, which contains a large amount of protein, cannot be adequately absorbed by water-absorbing polymers (details will be explained in the "Examples" section below). Therefore, neither the wastewater treatment pack described in Patent Document 1 nor the absorbent sheet described in Patent Document 2 can properly treat eggs (egg liquid).

[0013] Despite the ongoing issues with egg disposal, the reality is that during outbreaks of avian influenza, the primary focus has been on culling chickens, with virtually no effective countermeasures considered for eggs to date.

[0014] The present invention was made in view of the above-mentioned problems, and its object is to provide a waste egg treatment material and method that can easily and properly treat waste eggs (waste eggs) produced by chickens whose disposal is determined in conjunction with an outbreak of avian influenza.

[0015] Methods for solving problems

[0016] The waste egg treatment material of the present invention, which is used to solve the above-mentioned problems, is characterized in that it is a waste egg treatment material generated due to an outbreak of avian influenza, and contains pulp.

[0017] According to this waste egg treatment material, even when waste eggs are generated due to an outbreak of avian influenza, the material, which contains pulp, can efficiently absorb the protein-rich waste eggs (egg liquid) that cannot be adequately absorbed by superabsorbent polymers. Since the treated material, after absorbing the egg liquid, can be directly buried in the soil, waste eggs can be disposed of simply and properly. Furthermore, because the raw material of this treatment material contains pulp, it decomposes naturally when buried in the soil, minimizing the environmental impact. It should be noted that, in addition to landfilling, this treatment material can also be incinerated.

[0018] In the waste egg treatment material of the present invention, the pulp is preferably virgin pulp.

[0019] According to the waste egg processing material of this composition, by using virgin paper pulp with fewer impurities as the paper pulp, the absorbency of the egg liquid is increased.

[0020] In the waste egg treatment material of the present invention, the bulk density of the pulp is preferably 0.3 g / cm³. 3 above.

[0021] Based on the waste egg processing material described herein, if the bulk density of the pulp is 0.3 g / cm³... 3The above methods maintain the absorbency of the egg liquid while preserving the strength of the pulp after absorption. Therefore, the processing container containing waste eggs can be stabilized during transportation and landfill.

[0022] In the waste egg treatment material of the present invention, the moisture content of the pulp is preferably 20% by weight or less.

[0023] According to the waste egg treatment material of this composition, by setting the moisture content of the pulp to less than 20% by weight, it is possible to balance the absorbency of the egg liquid and the strength of the pulp after absorbing the egg liquid.

[0024] In the waste egg treatment material of the present invention, it is preferably formed in the form of plates and / or fragments.

[0025] The waste egg processing material according to this design is formed in a plate-like form, which provides morphological stability and facilitates handling. As a result, waste eggs can be stacked on the processing material within the processing container, improving processing efficiency. Furthermore, by forming it in fragmented form, the processing material can penetrate the gaps between the waste eggs within the processing container, thus efficiently absorbing the egg liquid produced from the waste eggs.

[0026] In the waste egg treatment material of the present invention, the specific gravity of the plate-shaped material is preferably 1.1 or more.

[0027] According to the waste egg processing material of this structure, since the specific gravity of the plate-shaped material is adjusted to 1.1 or more (a value greater than 1), the waste egg processing material can be prevented from floating when it is put into a flexible bag together with the waste eggs.

[0028] The method for treating waste eggs according to the present invention for solving the above-mentioned problems is characterized by comprising:

[0029] The pulp preparation process inside the processing container, and

[0030] The process of adding waste eggs into the aforementioned processing container.

[0031] According to the waste egg treatment method of this structure, inside the treatment container, the pulp can efficiently absorb and treat waste eggs (egg liquid) containing a large amount of protein that cannot be fully absorbed by water-absorbing polymers.

[0032] In the waste egg treatment method of the present invention, it is preferable to alternately repeat the above-described preparation step and the above-described input step.

[0033] According to the waste egg treatment method described herein, by alternately repeating the preparation and input processes, waste eggs can be stacked in the treatment container, thereby improving treatment efficiency.

[0034] In the waste egg treatment method of the present invention, it is preferable to put the waste eggs along with their shells into the above-mentioned input process.

[0035] According to the waste egg disposal method described herein, since the waste eggs can be disposed of intact even if the shells are cracked, the waste eggs can be disposed of together with the shells, requiring no effort in the disposal process and improving work efficiency.

[0036] In the waste egg treatment method of the present invention, it is preferable to use more than 15% of the above-mentioned pulp on a weight basis relative to the waste eggs, and to carry out the above-mentioned preparation step and input step.

[0037] According to the waste egg treatment method described herein, if the preparation and input processes are adjusted to use at least 15% pulp relative to the weight of the waste eggs, the pulp can reliably absorb the egg liquid. As a result, even if the waste eggs are added to the treatment container and it is full, there will be no leakage, thus improving treatment efficiency. Attached Figure Description

[0042] Embodiments of the waste egg treatment materials and waste egg treatment methods of the present invention will be described. However, the present invention is not limited to the following description.

[0043] [Materials for processing discarded eggs]

[0044] The waste egg treatment material of the present invention is formed by including pulp. Pulp is preferably included as the main raw material in the waste egg treatment material. Here, "as the main raw material" means that it comprises 90% by weight or more, preferably 99% by weight or more. Therefore, the waste egg treatment material of the present invention can be composed solely of pulp (100% pulp), or it can contain additives other than pulp such as binders, adhesives, excipients, fillers, preservatives, deodorizers, antibacterial agents, antiviral agents, colorants, and fragrances; however, the total amount of these additives is limited to 10% by weight.

[0045] The pulp can be wood pulp made from coniferous or broadleaf trees, or non-wood pulp made from grass or straw. Regarding this type of pulp, the inventors conducted various studies to consider its applicability to the disposal of discarded eggs during avian influenza outbreaks. The results showed that the pulp possesses excellent absorption capacity for discarded eggs (egg liquid) containing large amounts of protein, which cannot be adequately absorbed by absorbent polymers. Therefore, using the waste egg disposal material of the present invention, which contains pulp, allows for the simple and appropriate disposal of discarded eggs generated during avian influenza outbreaks. Furthermore, because the waste egg disposal material of the present invention contains pulp, it will naturally decompose if the treated material after absorbing the egg liquid is landfilled in the soil. Therefore, the waste egg disposal material of the present invention has a low environmental burden. It should be noted that, in addition to landfilling, the waste egg disposal material of the present invention, which contains pulp, can also be incinerated.

[0046] The pulp can be either virgin pulp or recycled pulp, but virgin pulp is preferred. Recycled pulp made from waste paper, newspapers, etc., may hinder the absorption of egg liquid due to residual ink and other oils, while virgin pulp has fewer impurities and therefore has a very good ability to absorb egg liquid.

[0047] The pulp should be selected based on suitable properties. Specifically, a bulk density of 0.3 g / cm³ is preferred. 3 The above, more preferably 0.34 g / cm 3 The above applies when the bulk density of the pulp is less than 0.3 g / cm³. 3 In some cases, due to insufficient absolute quantity of pulp, it may not be able to fully absorb the egg liquid. It should be noted that there is no specific upper limit to the bulk density of pulp; however, since pulp is a plant-based material, even after compaction, its bulk density in reality will not exceed 1.0 g / cm³. 3 Regarding the waste egg treatment material of this invention, the bulk density of the pulp is set to 0.3 g / cm³. 3 The above methods maintain the absorbency of the egg liquid while preserving the strength of the pulp after absorption. Therefore, the flexible bags (processing containers) containing waste eggs can be stabilized during transport and landfilling. It should be noted that the bulk density of the pulp can be determined from the volume and weight of the molded product. When the pulp is in an amorphous form (granules, flakes, fragments, etc.), it can be determined by its own weight in a container of a certain capacity, based on the container's volume and the weight of the pulp.

[0048] The preferred moisture content of the pulp is 20% by weight or less. If the moisture content of the pulp exceeds 20% by weight, its absorbency may not be fully utilized. It should be noted that there is no particular lower limit to the moisture content of the pulp; however, since some of the moisture is firmly adsorbed onto cellulose, the main component of the pulp, the moisture content will not be less than 1% by weight in practice, even after thorough drying. For the waste egg treatment material of this invention, by setting the moisture content of the pulp to 20% by weight or less, both the absorbency of the egg liquid and the strength of the pulp after absorbing the egg liquid can be balanced. It should be noted that the moisture content of the pulp can be measured, for example, using an infrared moisture meter.

[0049] The waste egg treatment material of the present invention, comprising pulp having the properties described above, can be used directly in fragment form or in a form shaped into plates, etc. Alternatively, fragments and plates (molded articles) can be used simultaneously. Here, a plate refers to an object having upper and lower surfaces that are circular, elliptical, polygonal, or irregular in shape when viewed from above and below, and having a thickness shorter than the upper and lower surfaces when viewed from the side. The plate-shaped treatment material can be obtained, for example, by cutting pulp blocks (compressed material) that can be obtained from a paper mill to an appropriate thickness. This plate-shaped treatment material can be used directly for the treatment of waste eggs. The waste egg treatment material formed in the form of plates is easy to handle due to its stable shape. As a result, waste eggs can be stacked on the treatment material in a flexible bag, improving treatment efficiency. It should be noted that when the waste egg treatment material is used directly in fragment form, the treatment material can enter the gaps between the waste eggs in the flexible bag, thus efficiently absorbing the egg liquid produced from the waste eggs.

[0050] The dimensions of the waste egg treatment material, formed in the form of a plate, can be appropriately set according to the shape and size of the flexible bag into which the waste eggs are placed, and the method of using the treatment material. For example, when 4 to 5 layers of treatment material and waste eggs are alternately stacked inside a common cylindrical flexible bag (diameter 1100 mm, height 1100 mm, capacity 1000 L), the dimensions of the treatment material are preferably set as follows: length and width 500 to 1000 mm, and thickness 10 to 150 mm. In this case, waste eggs and treatment material can be placed into the flexible bag until the bag's capacity is filled, enabling efficient treatment of waste eggs.

[0051] The specific gravity of the waste egg processing material formed in the form of a plate is preferably 1.1 or more, more preferably 1.27 or more. As described above, even if the bulk density of the pulp is 0.3 g / cm³... 3As mentioned above, when pulp is compressed into blocks (plates), its specific gravity will reach 1.1 or higher. If the specific gravity of these plates is adjusted to 1.1 or higher (a value greater than 1), the waste egg processing material can be prevented from floating when placed in a flexible bag along with discarded eggs. It should be noted that there is no specific upper limit to the specific gravity of the processing material; however, since pulp is a plant-based raw material, even with strong compression, its specific gravity will not exceed 1.7 in reality.

[0052] [Methods for disposing of discarded eggs]

[0053] The waste egg treatment method of the present invention is implemented using the aforementioned waste egg treatment material. The waste egg treatment method of the present invention includes a preparation step of placing pulp inside a flexible bag (treatment container) and an input step of placing waste eggs into the flexible bag. The pulp becomes the waste egg treatment material. According to the waste egg treatment method of the present invention, the treatment material can efficiently absorb and treat waste eggs (egg liquid) containing a large amount of protein that cannot be adequately absorbed by water-absorbing polymers.

[0054] <Configuration Process>

[0055] In the preparation process, the pulp (processing material) disposed inside the flexible bag can be granular or sheet-like; however, as mentioned above, it is preferable to use a sheet-like material shaped to match the shape and size of the flexible bag. Detailed descriptions of the pulp's properties are omitted as described above.

[0056] <Input Process>

[0057] In the input process, discarded eggs are placed onto the processing material. The eggs can be added shell and all. In this case, although the egg white may leak out due to cracked shells, it is absorbed by the processing material and does not accumulate at the bottom of the flexible bag. Furthermore, since even cracked eggshells can be processed directly, the process is labor-saving and improves operational efficiency.

[0058] <Alternating Operations>

[0059] The above-described preparation and feeding steps are preferably repeated alternately. This allows waste eggs to be stacked within the flexible bag, improving processing efficiency. Regarding the number of layers of waste eggs, when using a common cylindrical flexible bag (1100mm diameter, 1100mm height, 1000L capacity), 2 to 10 layers can be used with the processing material sandwiched in the middle; however, considering the appropriate thickness of the processing material, 4 to 5 layers are preferred. Furthermore, when alternating between the preparation and feeding steps, it is preferable to use at least 15% pulp relative to the weight of the waste eggs. This ensures that the processing material reliably absorbs the egg liquid. As a result, even if the flexible bag is filled to capacity with waste eggs, no leakage occurs, further improving processing efficiency.

[0060] <Post-processing>

[0061] Once the flexible bag is full, it can be directly buried in the soil for post-processing. According to the waste egg disposal method of the present invention, since the processing material uses pulp as the main raw material, the processing material decomposes naturally when buried in the soil, resulting in a small environmental burden. It should be noted that, in addition to burial, incineration is also an option.

[0062] Example

[0063] To confirm the performance and effectiveness of the waste egg treatment material of the present invention, flowability confirmation tests 1 and 2, stability confirmation tests, and stacking tests were conducted. The details of each test are as follows.

[0064] [Liquidity Confirmation Experiment 1]

[0065] If the treatment material that has absorbed the egg liquid from discarded eggs exhibits high fluidity, the material may flow along with the egg liquid and accumulate at the bottom of the flexible bag, potentially leaking out. Therefore, to confirm the fluidity of the treatment material that has absorbed the egg liquid, a fluidity confirmation test 1 (Examples 1 and 2, Comparative Example 1) was performed according to the following steps.

[0066] (1) Weigh out the egg liquid equivalent to 3 raw eggs that are considered as waste eggs and put it into a mixer (Waring vertical mixer WSM7Q, manufactured by Osaka Chemical Co., Ltd.).

[0067] (2) Add 20% of the processing materials (virgin pulp (Example 1), waste paper pulp (Example 2), superabsorbent polymer (Comparative Example 1)) relative to the weight of the egg liquid to the mixer.

[0068] (3) Start the mixer and mix at 41 rpm for 1 minute to mix the egg liquid with the processing materials.

[0069] (4) Stop the mixer and visually check the fluidity of the mixture of egg liquid and processing materials.

[0070] The following three treatment materials were used in the fluidity confirmation test 1. It should be noted that the treatment materials used in the fluidity confirmation test 2, stability confirmation test, and stacking test (described later) are the same as those described below.

[0071] (Example 1) Virgin pulp

[0072] • Seller: TECHNICA Contracts Co., Ltd.

[0073] Product Name: Pulsap (Dose B)

[0074] • Composition: Natural wood pulp (Pinus genus of evergreen trees: 60% by weight, Picea genus of conifers: 38% by weight, Amur fir: <2% by weight)

[0075] • Bulk density of pulp: 0.39 g / cm³ 3 (2.59cm) 3 / g)

[0076] • Specific gravity as a block (plate): 1.4

[0077] • Moisture content: 10% by weight

[0078] (Example 2) Waste paper pulp (waste paper fiber)

[0079] • Seller: Japan Creative Co., Ltd.

[0080] Product Name: 250kg Fiber

[0081] • Ingredients: Waste paper pulp

[0082] • Bulk density of pulp: same as virgin pulp

[0083] • Specific gravity as a block (board): the same as virgin pulp

[0084] • Moisture content: Same as virgin pulp

[0085] (Comparative Example 1) Superabsorbent polymer

[0086] • Seller: TECHNICA Contracts Co., Ltd.

[0087] Product Name: SAP High Spec

[0088] • Ingredients: Polyacrylic acid polymer

[0089] The results of Liquidity Confirmation Experiment 1 are expressed as follows: Figure 1 In Example 1, using virgin paper pulp as the treatment material, the treatment material absorbed the egg liquid well, and no flowability of the mixture of egg liquid and treatment material was observed. In Example 2, using waste paper pulp as the treatment material, although not as good as in Example 1, the treatment material still absorbed the egg liquid, and the flowability of the mixture of egg liquid and treatment material was basically not observed. In contrast, in Comparative Example 1, using a superabsorbent polymer as the treatment material, the treatment material could not absorb the egg liquid sufficiently, and as a result, the flowability of the mixture of egg liquid and treatment material was observed. This shows that treatment materials containing pulp are very useful for the treatment of waste eggs.

[0090] [Liquidity Confirmation Experiment 2]

[0091] Then, for the virgin pulp that showed an effect in suppressing the flowability of the treated material after absorbing egg liquid, flowability confirmation test 2 (Examples 3-5) was conducted according to the following steps to confirm the appropriate amount of treated material relative to egg liquid.

[0092] (1) Weigh out the egg liquid equivalent to 3 raw eggs that are considered as discarded eggs and put it into a mixer (Waring vertical mixer WSM7Q, manufactured by Osaka Chemical Co., Ltd.).

[0093] (2) The processed material (virgin pulp) was added to the mixer at ratios of 20% (Example 3), 15% (Example 4), and 10% (Example 5) relative to the weight of the egg liquid.

[0094] (3) Start the mixer and mix at 41 rpm for 1 minute to mix the egg liquid with the processing materials.

[0095] (4) Stop the mixer and after 20 minutes, visually check the fluidity of the mixture of egg liquid and processing materials.

[0096] The results of Liquidity Confirmation Experiment 2 are expressed as follows: Figure 2 In Example 3, the test involving mixing 20% ​​virgin pulp relative to the weight of the egg liquid was conducted under the same conditions as in Example 1, and no flowability was observed in the mixture of egg liquid and treatment material. In Example 4, the test involving mixing 15% virgin pulp relative to the weight of the egg liquid was less effective than in Example 3, but the flowability of the mixture of egg liquid and treatment material was essentially unobservable. In Example 5, the test involving mixing 10% virgin pulp relative to the weight of the egg liquid was slightly observed, but this was not a practical problem. Therefore, it is shown that when using virgin pulp as the treatment material, the ratio of the treatment material to the weight of the egg liquid is preferably set to 10% or more.

[0097] [Stability Confirmation Test]

[0098] When handling flexible bags containing discarded eggs, it is required that the contents remain stable and that no leakage occurs. Therefore, in order to confirm the stability of the processed material after absorbing egg liquid, stability confirmation tests were conducted according to the following steps (Examples 6 and 7).

[0099] (1) Place a conical container (upper diameter 70mm, lower diameter 100mm, height 60mm) on the test bench (diameter 300mm) of the mortar flow tester (c-206, West Japan Tester Co., Ltd.).

[0100] (2) Fill the conical container with a mixture of egg liquid (but equivalent to 5 raw eggs) prepared in the same manner as in flowability confirmation test 1 and the treatment materials [virgin pulp (Example 6), waste paper pulp (Example 7)].

[0101] (3) After carefully removing the conical container, vibrate the mortar flow tester up and down 50 times and visually confirm the shape change of the mixture.

[0102] (4) Remove the mixture from the test bench, absorb the moisture adhering to the surface of the test bench with kitchen paper towels, and calculate the amount of water separated based on the weight difference of the kitchen paper towels before and after absorption.

[0103] The results of the stability confirmation test are expressed as follows: Figure 3 In Example 6, using virgin paper pulp as the treatment material, the appearance of the mixture of egg liquid and treatment material after the slurry flow test did not change significantly, indicating a stable state. Furthermore, the amount of water separation was only 0.04g, so there was no concern about leakage. In Example 7, using waste paper pulp as the treatment material, although the shape of the mixture of egg liquid and treatment material slightly collapsed after the slurry flow test, it remained relatively stable. Additionally, the amount of water separation was controlled at a relatively small level of 2.15g, which is a level with few practical problems. Using a treatment material containing paper pulp to treat waste eggs in this way demonstrates its stability during handling in flexible bags and eliminates leakage issues, thus proving its usefulness.

[0104] [Stacking Test]

[0105] When placing discarded eggs into a flexible bag, it is necessary to contain as many discarded eggs as possible while preventing leakage of the egg liquid. For this purpose, the discarded eggs need to be stacked in multiple layers. Therefore, to confirm the containment capacity of discarded eggs in the flexible bag, a stacking test was conducted according to the following steps (Examples 8 and 9).

[0106] (1) Approximately 55g of treatment materials [virgin pulp (Example 8), waste paper pulp (Example 9)] are added to the container to form a treatment layer (first layer).

[0107] (2) Place 3 to 4 eggs (50 to 70g each) with the eggshells on the treatment layer to form an egg layer, and place about 55g of treatment material on top to form the next treatment layer (the second layer).

[0108] (3) Repeat the above (2) operation to form the 5th layer.

[0109] (4) Visually confirm the status of floors 1 to 5.

[0110] The results of the stacking test are expressed as follows: Figure 4 In Example 8, where virgin paper pulp was used as the treatment material, the egg liquid was immediately absorbed by the treatment material even if the eggs broke during stacking, preventing leakage and flow of the mixture between egg liquid and treatment material. In Example 9, where waste paper pulp was used as the treatment material, slight adhesion of egg liquid to the treatment material was observed if an egg broke during stacking; however, there was no severe leakage or significant flow of the mixture. Using a treatment material containing paper pulp in this way allows for the stacking of waste eggs in flexible bags while preventing leakage, demonstrating its significant advantage in improving treatment efficiency.
