Material for treating discarded eggs and method for treating discarded eggs
[0001] The present invention relates to a material for treating chicken eggs (egg liquid) and a method for treating the same.
[0002] For example, in Japan, when highly pathogenic avian influenza (hereinafter simply referred to as "avian influenza") breaks out, a culling order is issued by the prefectural governor, and chickens are culled at poultry farms. The culled chickens are sterilized with lime, packed into flexible container bags (hereinafter referred to as "flexible container bags"), and buried in the ground.
[0003] Here, when a poultry farm raises a large number of chickens, if a large number of chickens are culled at once, there is a risk that the sterilization and burial work will not be able to keep up, and the chicken carcasses will rot. Therefore, when culling chickens, a limit is set on the number that can be culled at one time from a hygienic standpoint.
[0004] However, if the number of chickens to be culled becomes enormous, the chickens waiting to be culled will lay eggs every day, resulting in a large amount of eggs. These eggs will also be subject to disposal (disposal) just like the chickens, and will be packed into flexible container bags and buried.
[0005] However, when eggs are packed into a flexible container bag, the shells crack and the egg liquid accumulates inside the bag. Therefore, when disposing of eggs, in order to prevent the egg liquid from leaking out of the flexible container bag, only half (400-500 L) of the flexible container bag's capacity (1000 L) can be packed into the bag. Furthermore, because the contents of flexible container bags filled with eggs become liquid, they cannot be stacked two-tiered during transportation and are unstable when buried.
[0006] Therefore, it is conceivable to absorb the liquid released from cracked eggs using, for example, a domestic wastewater absorption treatment pack as disclosed in Patent Document 1 or a water-absorbing sheet as disclosed in Patent Document 2. Incidentally, the domestic wastewater absorption treatment pack of Patent Document 1 absorbs and treats domestic wastewater such as leftover instant noodle soup or leftover miso soup by using the action of a water-absorbing polymer enclosed in the pack. The water-absorbing sheet of Patent Document 2 absorbs the moisture released from meat, fish, vegetables, etc. by using the action of a water-absorbing polymer contained in its water-absorbing layer.
[0007] Utility Model Registration No. 3111826 JP 2017-47341 A
[0008] However, according to test studies conducted by the present inventors, it has been found that egg liquid, which contains a large amount of protein, is not sufficiently absorbed by water-absorbent polymers (details will be explained in the "Examples" below). Therefore, chicken eggs (egg liquid) cannot be appropriately treated with the domestic wastewater absorption treatment pack disclosed in Patent Document 1 or the water-absorbent sheet disclosed in Patent Document 2.
[0009] Despite the problems associated with disposing of chicken eggs, the main response to an outbreak of avian influenza has been to cull chickens, and little consideration has been given to effective measures for chicken eggs.
[0010] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a material for treating discarded eggs that can easily and appropriately treat eggs (discarded eggs) laid by hens that have been decided to be disposed of due to an outbreak of avian influenza, and a method for treating the same.
[0011] The characteristic feature of the material for treating discarded eggs according to the present invention, which is intended to solve the above-mentioned problems, is that it is a material for treating discarded eggs resulting from an outbreak of avian influenza, and contains pulp.
[0012] According to the discarded egg treatment material of this configuration, even in the event of discarded eggs being generated due to an outbreak of avian influenza, the use of a treatment material containing pulp makes it possible to efficiently absorb discarded eggs (egg liquid), which contain a large amount of protein that cannot be fully absorbed by water-absorbent polymers. The treatment material that has absorbed the egg liquid can be buried in the ground as is, allowing for easy and appropriate disposal of discarded eggs. Furthermore, because this treatment material contains pulp as a raw material, the treatment material will naturally decompose when buried in the ground, reducing the burden on the environment. In addition to being buried in the ground, this treatment material can also be incinerated.
[0013] In the waste egg treatment material according to the present invention, the pulp is preferably virgin pulp.
[0014] According to the waste egg treatment material of this configuration, the pulp used is virgin pulp with few impurities, which results in high absorption of egg liquid.
[0015] In the waste egg treatment material according to the present invention, the bulk density of the pulp is 0.3 g / cm 3 It is preferable that this is equal to or greater than this.
[0016] According to the waste egg treatment material of this configuration, the bulk density of the pulp is 0.3 g / cm 3 If the above conditions are met, the strength of the pulp that has absorbed the egg liquid can be maintained while maintaining the egg liquid absorption capacity, and therefore the treatment container containing discarded eggs can be stabilized when transporting or burying the treatment container.
[0017] In the waste egg treatment material according to the present invention, the moisture content of the pulp is preferably 20% by weight or less.
[0018] According to the waste egg treatment material of this configuration, by setting the moisture content of the pulp to 20% by weight or less, it is possible to achieve both the ability to absorb egg liquid and the strength of the pulp that has absorbed the egg liquid.
[0019] The waste egg treatment material of the present invention is preferably configured as a plate and / or a strip.
[0020] The discarded egg treatment material of this configuration is configured as a plate, which stabilizes the shape of the treatment material and makes it easy to handle. As a result, discarded eggs can be stacked on top of the treatment material in the treatment container, improving treatment efficiency. Furthermore, by configuring it as a strip, the treatment material can penetrate into the gaps between discarded eggs in the treatment container, making it possible to efficiently absorb egg liquid generated from discarded eggs.
[0021] In the material for treating discarded eggs according to the present invention, the specific gravity of the plate-like material is preferably 1.1 or more.
[0022] According to the waste egg treatment material of this configuration, the specific gravity of the plate-like material is adjusted to 1.1 or more (a value greater than 1), so when it is placed into a flexible container bag together with the waste eggs, the waste egg treatment material can be prevented from floating up.
[0023] A characteristic feature of the discarded egg processing method according to the present invention for solving the above-mentioned problems is that it includes a disposing step of disposing pulp inside a processing container, and a throwing step of throwing discarded eggs into the processing container.
[0024] According to the discarded egg processing method of this configuration, discarded eggs (egg liquid) containing a large amount of protein that cannot be sufficiently absorbed by water-absorbent polymers can be efficiently absorbed into the pulp inside the processing container and processed.
[0025] In the method for treating discarded eggs according to the present invention, it is preferable that the arranging step and the introducing step are repeated alternately.
[0026] According to the discarded egg processing method of this configuration, by alternately repeating the arranging step and the throwing step, it becomes possible to stack the discarded eggs in the processing container, thereby improving processing efficiency.
[0027] In the method for treating discarded eggs according to the present invention, it is preferable that the discarded eggs are charged together with their shells in the charging step.
[0028] According to the method for disposing of discarded eggs of this configuration, even if the shells of discarded eggs are broken, they can be disposed of as they are, so that discarded eggs can be put in with their shells, which saves time and effort for disposal and improves work efficiency.
[0029] In the method for treating discarded eggs according to the present invention, the arranging step and the adding step are preferably carried out so that the pulp accounts for 15% or more by weight of the discarded eggs.
[0030] According to the discarded egg processing method of this configuration, if the pulp is adjusted to use 15% or more by weight of the discarded eggs when performing the placing step and the adding step, the egg liquid can be reliably absorbed by the pulp. As a result, even if the processing container is filled with discarded eggs, liquid leakage does not occur, and processing efficiency is improved.

Fig. 3 is a table summarizing the results of the stability confirmation test. Fig. 4 is a table summarizing the results of the lamination test.
[0032] The following describes embodiments of the material for treating discarded eggs and the method for treating discarded eggs of the present invention, although the present invention is not limited to the following descriptions.
[0033] [Material for Treating Waste Eggs] The material for treating waste eggs of the present invention is configured to contain pulp. Preferably, pulp is contained as the main ingredient in the material for treating waste eggs. Here, "as the main ingredient" means that the material contains 90% by weight or more, preferably 99% by weight or more. Therefore, the material for treating waste eggs of the present invention may be composed solely of pulp (100% pulp), or may contain, in addition to pulp, additives such as binders, adhesives, excipients, fillers, preservatives, deodorizers, antibacterial agents, antiviral agents, colorants, and fragrances, in a total amount up to 10% by weight.
[0034] The pulp may be wood pulp produced from coniferous or broad-leaved trees, or non-wood pulp produced from grass or straw. The inventors of the present invention considered the possibility of using such pulp to treat discarded eggs (discarded eggs), which are a problem during outbreaks of avian influenza. As a result of various investigations, they discovered that pulp has an excellent ability to absorb discarded eggs (egg liquid), which contain a large amount of protein and cannot be fully absorbed by water-absorbent polymers. Therefore, by using the discarded egg treatment material of the present invention containing pulp, discarded eggs resulting from an outbreak of avian influenza can be easily and appropriately treated. Furthermore, since the discarded egg treatment material of the present invention contains pulp, when the treatment material that has absorbed the egg liquid is buried in the soil, the treatment material will naturally decompose. Therefore, the discarded egg treatment material of the present invention has a low environmental impact. The discarded egg treatment material of the present invention containing pulp can be buried in the soil or incinerated.
[0035] The pulp may be either virgin pulp or recycled pulp, but is preferably virgin pulp. Recycled pulp made from waste paper, newspaper, etc. may have residual oils such as ink that inhibit the absorption of egg liquid, but virgin pulp has few impurities and is therefore excellent in its ability to absorb egg liquid.
[0036] Pulp having appropriate properties is selected. Specifically, the bulk density of the pulp is 0.3 g / cm 3 It is preferable that the density is 0.34 g / cm or more. 3 It is more preferable that the bulk density of the pulp is 0.3 g / cm or more. 3 If the bulk density is less than 1.0 g / cm, the absolute amount of pulp will be insufficient, and the egg liquid may not be sufficiently absorbed. Although there is no particular upper limit on the bulk density of pulp, since pulp is a plant-derived raw material, in reality, even if compacted, the bulk density is 1.0 g / cm. 3 The waste egg treatment material of the present invention has a bulk density of pulp of 0.3 g / cm 3By doing so, it is possible to maintain the strength of the pulp that has absorbed the egg liquid while maintaining the egg liquid absorption capacity. Therefore, the flexible container bag (treatment container) containing discarded eggs can be stabilized when transporting or burying the flexible container bag. If the pulp is a molded product, the bulk density of the pulp can be determined from the volume and weight of the molded product. If the pulp is an irregular product (granules, flakes, small pieces such as crushed material), the bulk density can be determined by filling the pulp into a container of a certain capacity under its own weight and then calculating the volume of the container and the weight of the pulp filled.
[0037] The moisture content of the pulp is preferably 20% by weight or less. If the moisture content of the pulp exceeds 20% by weight, there is a risk that the pulp will not be able to fully exhibit its absorption capacity. Although there is no particular limitation on the lower limit of the moisture content of the pulp, since a portion of the moisture is firmly adsorbed to cellulose, the main component of the pulp, in reality, even if the pulp is thoroughly dried, the moisture content will not fall below 1% by weight. By setting the moisture content of the pulp to 20% by weight or less, the waste egg treatment material of the present invention can achieve both the absorption capacity of the egg liquid and the strength of the pulp that has absorbed the egg liquid. The moisture content of the pulp can be measured, for example, using an infrared moisture meter or the like.
[0038] The discarded egg treatment material of the present invention, which contains pulp having the above-described properties, may be used in the form of small pieces or formed into a plate-like object or the like. Alternatively, both small pieces and a plate-like object (molded product) may be used simultaneously. Here, a plate-like object has upper and lower surfaces that are circular, oval, polygonal, irregular, or other shapes when viewed from above and below, and a thickness that is shorter than the length of the upper and lower surfaces when viewed from the side. A plate-like treatment material can be obtained, for example, by cutting a pulp block (compressed product) available from a paper mill to an appropriate thickness. This plate-like treatment material can be used directly for discarded egg treatment. The discarded egg treatment material in the form of a plate is stable in shape and therefore easy to handle. As a result, discarded eggs can be stacked on top of the treatment material within a flexible container bag, improving treatment efficiency. When the discarded egg treatment material is used in the form of small pieces, the treatment material can penetrate into the gaps between the discarded eggs within the flexible container bag, thereby efficiently absorbing egg liquid generated from the discarded eggs.
[0039] The size of the waste egg treatment material, which is configured as a plate-like object, can be set appropriately depending on the shape and size of the flexible container bag into which the waste eggs are placed, how the treatment material is used, etc. For example, when treatment material and waste eggs are stacked alternately in 4 to 5 layers inside a typical cylindrical flexible container bag (diameter 1100 mm, height 1100 mm, capacity 1000 L), it is preferable to set the size of the treatment material so that it is 500 to 1000 mm in length and width and 10 to 150 mm in thickness. In this case, it becomes possible to put waste eggs and treatment material into the flexible container bag until it is full, allowing waste eggs to be treated efficiently.
[0040] The specific gravity of the waste egg treatment material formed into a plate-like material is preferably 1.1 or more, more preferably 1.27 or more. As described above, the bulk density of the pulp is 0.3 g / cm 3Even if the pulp is above this level, when it is compressed and formed into a block (plate-shaped object), its specific gravity will be 1.1 or more. In this way, if the specific gravity of the plate-shaped object is adjusted to 1.1 or more (a number greater than 1), it is possible to prevent the waste egg treatment material from floating up when it is placed into a flexible container bag together with the waste eggs. There is no particular upper limit on the specific gravity of the treatment material, but because pulp is a plant-derived raw material, in reality the specific gravity will not exceed 1.7 even if it is compressed and formed with a great force.
[0041] [Method for treating discarded eggs] The method for treating discarded eggs of the present invention is carried out using the treatment material for discarded eggs described above. The method for treating discarded eggs of the present invention includes an arrangement step of placing pulp inside a flexible container bag (treatment container) and a charging step of charging discarded eggs into the flexible container bag. The pulp serves as a treatment material for discarded eggs. According to the method for treating discarded eggs of the present invention, discarded eggs (egg liquid) that contain a large amount of protein that cannot be sufficiently absorbed by water-absorbent polymers can be efficiently absorbed and treated by the treatment material.
[0042] <Placement step> In the placement step, the pulp (treatment material) placed inside the flexible container bag may be in granular or flake form, but as described above, it is preferable to use a plate-like material shaped to fit the shape and size of the flexible container bag. The properties of the pulp are as described above, so a detailed description will be omitted.
[0043] <Charging step> In the charging step, discarded eggs are charged onto the treatment material. The discarded eggs may be charged with their shells still intact. In this case, the shells of the discarded eggs will crack and the egg liquid will leak out, but the egg liquid will not accumulate at the bottom of the flexible container bag because it is absorbed by the treatment material. Furthermore, even if the shells of the discarded eggs are cracked, they can be treated as they are, which reduces the time and effort required for treatment and improves work efficiency.
[0044] <Alternating Operation> The above-mentioned placing step and charging step are preferably repeated alternately. This allows discarded eggs to be stacked in the flexible container bag, improving treatment efficiency. When using a typical cylindrical flexible container bag (diameter 1100 mm, height 1100 mm, capacity 1000 L), the discarded eggs can be stacked in 2 to 10 layers with the treatment material sandwiched between them. However, considering the appropriate thickness of the treatment material, 4 to 5 layers is preferable. Furthermore, when performing the alternating operation of the placing step and charging step, it is preferable to perform the placing step and charging step so that pulp is used in an amount of 15% or more by weight relative to the discarded eggs. This allows the egg liquid to be reliably absorbed into the treatment material. As a result, even if discarded eggs are charged until the flexible container bag is full, liquid leakage does not occur, improving treatment efficiency.
[0045] <Post-treatment> When the flexible container bag is full, the post-treatment is to bury the flexible container bag as it is in the ground. According to the method for treating discarded eggs of the present invention, the treatment material is made mainly from pulp, so when buried in the ground the treatment material will naturally decompose, resulting in a small burden on the environment. In addition to burying in the ground, incineration is also possible.
[0046] In order to confirm the performance and effect of the waste egg treatment material of the present invention, fluidity confirmation tests 1 and 2, a stability confirmation test, and a lamination test were carried out. Each test is described below.
[0047] [Fluidity Confirmation Test 1] If the treatment material that absorbed the egg liquid from discarded eggs exhibited high fluidity, the treatment material would flow with the egg liquid, accumulate at the bottom of the flexible container bag, and potentially leak from the flexible container bag. Therefore, to confirm the fluidity of the treatment material that absorbed the egg liquid, Fluidity Confirmation Test 1 (Examples 1 and 2, Comparative Example 1) was conducted according to the following procedure. (1) The egg liquid from three raw eggs, which were assumed to be discarded eggs, was weighed and placed in a mixer (Waring Stand Mixer WSM7Q, manufactured by Osaka Chemical Co., Ltd.). (2) 20% of the treatment material (virgin pulp (Example 1), recycled paper pulp (Example 2), and superabsorbent polymer (Comparative Example 1)) was placed in the mixer based on the weight of the egg liquid. (3) The mixer was started and stirred at 41 rpm for 1 minute to mix the egg liquid and the treatment material. (4) The mixer was stopped, and the fluidity of the mixture of egg liquid and treatment material was visually confirmed.
[0048] The following three types of treatment materials were used in fluidity confirmation test 1. The treatment materials used in fluidity confirmation test 2, stability confirmation test, and lamination test, which will be described later, were also the same as those described below. (Example 1) Virgin pulp Seller: Technica Godo Co., Ltd. Product name: Pulsap (agent B) Ingredients: Natural wood pulp (evergreen tall trees of the genus Pinus of the family Pinaceae: 60% by weight, softwood trees of the genus Picea of the family Pinaceae: 38% by weight, balsam fir: <2% by weight) Bulk density as pulp: 0.39 g / cm 3 (2.59 cm 3 / g) Specific gravity as block (plate): 1.4 Moisture content: 10% by weight (Example 2) Recycled paper pulp (recycled paper fiber) Seller: Japan Creative Co., Ltd. Product name: 250 kg Fiber Ingredients: Recycled paper pulp Bulk density as pulp: Equivalent to virgin pulp Specific gravity as block (plate): Equivalent to virgin pulp Moisture content: Equivalent to virgin pulp (Comparative Example 1) Superabsorbent polymer Seller: Technica Godo Co., Ltd. Product name: SAP High Spec Ingredients: Polyacrylic acid polymer
[0049] The results of fluidity confirmation test 1 are shown in Figure 1. In the test of Example 1, which used virgin pulp as the treatment material, the treatment material absorbed the egg liquid well, and no fluidity was observed in the mixture of the egg liquid and the treatment material. In the test of Example 2, which used recycled paper pulp as the treatment material, the treatment material absorbed the egg liquid, although not as well as in Example 1, and almost no fluidity was observed in the mixture of the egg liquid and the treatment material. In contrast, in the test of Comparative Example 1, which used a highly absorbent polymer as the treatment material, the treatment material was unable to sufficiently absorb the egg liquid, and as a result, fluidity was observed in the mixture of the egg liquid and the treatment material. Thus, it was demonstrated that treatment materials containing pulp are very useful for treating discarded eggs.
[0050] [Fluidity Confirmation Test 2] Next, for the virgin pulp that was effective in suppressing the fluidity of the treatment material that absorbed the egg liquid, in order to confirm the appropriate amount of treatment material to be added to the egg liquid, Fluidity Confirmation Test 2 (Examples 3 to 5) was conducted according to the following procedure. (1) Egg liquid equivalent to three raw eggs, simulating discarded eggs, was weighed and added to a mixer (Waring Stand Mixer WSM7Q, manufactured by Osaka Chemical Co., Ltd.). (2) The treatment material (virgin pulp) was added to the mixer in ratios of 20% (Example 3), 15% (Example 4), and 10% (Example 5) relative to the weight of the egg liquid. (3) The mixer was started and stirred at 41 rpm for 1 minute to mix the egg liquid and the treatment material. (4) The mixer was stopped, and after 20 minutes, the fluidity of the mixture of egg liquid and treatment material was visually confirmed.
[0051] The results of fluidity confirmation test 2 are shown in Figure 2. In the test of Example 3, in which 20% virgin pulp was mixed relative to the weight of the egg liquid, under the same conditions as Example 1, no fluidity was observed in the mixture of egg liquid and treatment material. In the test of Example 4, in which 15% virgin pulp was mixed relative to the weight of the egg liquid, almost no fluidity was observed in the mixture of egg liquid and treatment material, although this was not as good as in Example 3. In the test of Example 5, in which 10% virgin pulp was mixed relative to the weight of the egg liquid, some fluidity was observed in the mixture of egg liquid and treatment material, but this was not a problem in practical use. Therefore, it was shown that when virgin pulp is used as the treatment material, it is preferable to blend the treatment material in an amount of 10% or more relative to the weight of the egg liquid.
[0052] [Stability Confirmation Test] When transporting flexible container bags containing discarded eggs, it is necessary for the contents to be stable and for liquid leakage to be prevented. Therefore, to confirm the stability of the treatment material that had absorbed the egg liquid, stability confirmation tests (Examples 6 and 7) were conducted according to the following procedure. (1) A cone container (top diameter 70 mm, bottom diameter 100 mm, height 60 mm) was placed on the table (diameter 300 mm) of a mortar flow tester (C-206, Nishinippon Testing Machine Co., Ltd.). (2) The cone container was filled with a mixture of egg liquid (equivalent to five raw eggs) and treatment material [virgin pulp (Example 6) and recycled paper pulp (Example 7)] prepared using the same procedure as in Flow Confirmation Test 1. (3) After carefully removing the cone container, the mortar flow tester was vibrated up and down 50 times, and any change in the shape of the mixture was visually confirmed. (4) Remove the mixture from the table, allow kitchen paper to absorb the water adhering to the surface of the table, and calculate the amount of water released from the difference in weight of the kitchen paper before and after absorption.
[0053] The results of the stability confirmation test are shown in Figure 3. In the test of Example 6, in which virgin pulp was used as the treatment material, no significant change was observed in the appearance of the mixture of egg liquid and treatment material after the mortar flow test, and it was stable. Furthermore, the amount of water syneresis was only 0.04 g, so there was no risk of liquid leakage. In the test of Example 7, in which recycled paper pulp was used as the treatment material, the shape of the mixture of egg liquid and treatment material after the mortar flow test was slightly distorted, but it was relatively stable. Furthermore, the amount of water syneresis was kept to a small amount of 2.15 g, which posed few practical problems. Thus, it was demonstrated that treating discarded eggs with a treatment material containing pulp is very useful, as it provides stability when transported in flexible container bags and does not pose a problem of liquid leakage.
[0054] [Layering Test] When discarded eggs are placed in a flexible container bag, it is necessary to accommodate as many discarded eggs as possible while preventing leakage of egg liquid. To achieve this, discarded eggs must be stacked in multiple layers. Therefore, to confirm the discarded egg capacity of a flexible container bag, a layering test (Examples 8 and 9) was conducted according to the following procedure. (1) Approximately 55 g of treatment material [virgin pulp (Example 8), recycled paper pulp (Example 9)] was placed in the container to form a treatment layer (first layer). (2) Three to four eggs (50 to 70 g per egg) with their shells were placed on top of the treatment layer to form an egg layer, and approximately 55 g of treatment material was placed on top of that to form the next treatment layer (second layer). (3) The above procedure (2) was repeated to form up to the fifth layer. (4) The condition of layers 1 to 5 was visually confirmed.
[0055] The results of the stacking test are shown in Figure 4. In the test of Example 8, in which virgin pulp was used as the treatment material, even if the eggs cracked during stacking, the egg liquid was immediately absorbed by the treatment material, so there was no leakage of the egg liquid or flow of the mixture of the egg liquid and the treatment material. In the test of Example 9, in which recycled paper pulp was used as the treatment material, when the eggs cracked during stacking, the egg liquid slightly clung to the treatment material, but there was no severe leakage of the egg liquid or significant flow of the mixture of the egg liquid and the treatment material. Thus, it was demonstrated that the use of a treatment material containing pulp is extremely useful in terms of improving treatment efficiency, as it allows discarded eggs to be stacked in a flexible container bag while preventing leakage of the egg liquid.
[0056] The discarded egg treatment material and discarded egg treatment method of the present invention are used to treat eggs (discarded eggs) laid by hens that have been decided to be disposed of due to an outbreak of avian influenza, but can also be used to treat other eggs (for example, eggs that have passed their expiration date, eggs that are not suitable for sale, or eggs that have to be discarded for some reason).
