Description

[Technical field]

[0001] The present invention relates to a material for treating chicken eggs (egg liquid) and a method for treating the same. [Background technology]

[0002] When highly pathogenic avian influenza (hereafter simply referred to as "avian influenza") occurs, a prefectural governor issues an order to kill chickens, and chickens are culled at poultry farms. The killed chickens are sterilized with lime, packed into flexible container bags, and buried in the ground.

[0003] Here, when a chicken farm has 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, from a hygienic standpoint, when culling chickens, a limit is set on the number of chickens that can be culled at one time.

[0004] However, if the number of chickens to be culled becomes huge, 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 FIBC bags and buried.

[0005] However, when eggs are packed into a FIBC, the shells crack and the egg liquid accumulates inside the bag. Therefore, when disposing of eggs, it is only possible to pack less than half (400-500L) of the FIBC's capacity (1000L) in order to prevent the egg liquid from leaking out of the bag. In addition, FIBC bags filled with eggs cannot be stacked two-levels during transportation because the contents are liquid, and they become unstable when buried.

[0006] Therefore, it is conceivable to absorb the egg liquid generated from cracked chicken eggs using, for example, a domestic wastewater absorption treatment pack as in Patent Document 1 or a water-absorbing sheet as in Patent Document 2. Incidentally, the domestic wastewater absorption treatment pack in Patent Document 1 absorbs and treats domestic wastewater such as leftover cup noodle soup and leftover miso soup by the action of the water-absorbing polymer enclosed in the pack. The water-absorbing sheet in Patent Document 2 absorbs the moisture released from meat, fish, vegetables, etc. by the action of the water-absorbing polymer contained in the water-absorbing layer. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Utility Model Registration No. 3111826 [Patent Document 2] JP 2017-47341 A Summary of the Invention [Problem to be solved by the invention]

[0008] However, according to the experimental research conducted by the present inventors, it was found that egg liquid, which contains a lot of protein, is not sufficiently absorbed by water-absorbing 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 as in Patent Document 1 or the water-absorbing sheet as in Patent Document 2.

[0009] Thus, despite the problems involved in disposing of chicken eggs, the main response to an avian influenza outbreak has been to cull the chickens, and little consideration has been given to effective measures regarding 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, which 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. [Means for solving the problem]

[0011] The characteristic configuration of the waste egg treatment material according to the present invention for solving the above problems is as follows: The main raw material is pulp.

[0012] According to the waste egg treatment material of this configuration, the treatment material is made mainly of pulp, so that it is possible to efficiently absorb waste eggs (egg liquid) that contain a lot of protein that cannot be fully absorbed by absorbent polymers. The treatment material that has absorbed the egg liquid can be buried in the ground as is, so that waste eggs can be easily and appropriately treated. In addition, because this treatment material is made mainly of pulp, it naturally decomposes when buried in the ground, and the burden on the environment is small. 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 More preferably, it 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 the treatment container is transported or buried.

[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 material for treating discarded eggs 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] In the waste egg treatment material according to the present invention, It is preferably configured as plates and / or strips.

[0020] According to the discarded egg treatment material of this configuration, by forming it as a plate-like object, the shape of the treatment material is stable and easy to handle. As a result, it becomes possible to stack the discarded eggs on the treatment material in the treatment container, improving the treatment efficiency. Furthermore, by forming it as a strip, the treatment material can penetrate into the gaps between the discarded eggs in the treatment container, making it possible to efficiently absorb the egg liquid generated from the discarded eggs.

[0021] In the waste egg treatment material according to the present invention, The specific gravity of the plate-like object is preferably 1.1 or more.

[0022] According to the waste egg treatment material of this configuration, the specific gravity of the plate-shaped material is adjusted to 1.1 or more (a numerical value greater than 1), so that when it is placed into a flexi-con bag together with the waste eggs, the waste egg treatment material can be prevented from floating up.

[0023] The characteristic configuration of the method for treating discarded eggs according to the present invention for solving the above problems is as follows: A placement step of placing pulp inside a treatment vessel; A step of introducing discarded eggs into the processing container; The purpose of this study is to encompass the above.

[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 absorbent polymers can be efficiently absorbed by 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 placing step and the introducing step are repeated alternately.

[0026] According to the discarded egg processing method configured as above, by alternately repeating the arranging step and the introducing 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, In the charging step, the discarded eggs are preferably charged together with their shells.

[0028] According to the method for disposing of discarded eggs of this configuration, even if the shells of the discarded eggs are cracked, the discarded eggs can be disposed of as they are, so that the discarded eggs can be put in together with the 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 placing and introducing steps are preferably carried out so that the pulp is used in an amount of 15% or more by weight relative to the discarded eggs.

[0030] According to the discarded egg processing method of this configuration, when performing the placing step and the feeding step, if the pulp is adjusted to be used at 15% or more by weight of the discarded eggs, the egg liquid can be reliably absorbed by the pulp. As a result, even if the processing container is filled with discarded eggs, no liquid leakage occurs, and processing efficiency is improved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] The following describes an embodiment of the waste egg treating material and the waste egg treating method of the present invention. However, the present invention is not limited to the following description.

[0033] [Materials for treating discarded eggs] The waste egg treatment material of the present invention is made primarily from pulp. Here, "made primarily from" means that the raw material contains 90% by weight or more, preferably 99% by weight or more. Therefore, the waste egg treatment material of the present invention may be made only from pulp (100% pulp), or may contain, in addition to pulp, additives such as binders, adhesives, excipients, fillers, preservatives, deodorants, antibacterial agents, antiviral agents, colorants, and fragrances, up to a total of 10% by weight.

[0034] The pulp may be wood pulp made from coniferous or broad-leaved trees, or non-wood pulp made from grass or straw. The present inventors considered whether such pulp could be used to treat chicken eggs (discarded eggs), which are a problem when avian influenza breaks out, and conducted various studies, resulting in a new finding that pulp has an excellent ability to absorb discarded eggs (egg liquid) that contain a large amount of protein that cannot be fully absorbed by water-absorbent polymers. Therefore, by using the waste egg treatment material of the present invention, which uses pulp as the main raw material, waste eggs can be easily and appropriately treated. In addition, since the waste egg treatment material of the present invention uses pulp as the main raw material, when the treatment material that absorbs the egg liquid is buried in the ground, the treatment material naturally decomposes. Therefore, the waste egg treatment material of the present invention has a small load on the environment. In addition, the waste egg treatment material of the present invention, which uses pulp as the main raw material, can be buried in the ground or incinerated.

[0035] The pulp may be either virgin pulp or recycled pulp, but is preferably virgin pulp. Recycled pulp made from waste paper, newspapers, etc. may be inhibited from absorbing egg liquid due to residual oils such as ink, but virgin pulp has a low impurity content and is therefore extremely excellent in absorbing egg liquid.

[0036] Pulp with appropriate properties is selected. Specifically, the bulk density of the pulp is 0.3 g / cm 3 It is preferable that the content 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 is 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 raw material derived from plants, in reality, the bulk density is limited to 1.0 g / cm even if it is compacted. 3 The waste egg treatment material of the present invention has a bulk density of 0.3 g / cm3. 3 By 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 FIBC bag (treatment container) containing discarded eggs can be stabilized when the FIBC bag is transported or buried. If the pulp is a molded product, the bulk density of the pulp can be calculated from the volume and weight of the molded product. If the pulp is an irregular product (granules, flakes, crushed pieces, etc.), the bulk density can be calculated 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 in.

[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, the pulp may not be able to fully exert its absorbing ability. Although there is no particular limit to the lower limit of the moisture content of the pulp, since a part of the moisture is firmly adsorbed to the cellulose, which is the main component of the pulp, the moisture content will not actually fall below 1% by weight even if the pulp is thoroughly dried. The waste egg treatment material of the present invention can achieve both the absorption power of the egg liquid and the strength of the pulp that has absorbed the egg liquid by making the moisture content of the pulp, which is the main raw material, 20% by weight or less. The moisture content of the pulp can be measured, for example, by an infrared moisture meter or the like.

[0038] The waste egg treatment material of the present invention, which uses pulp having the above-mentioned properties as a main raw material, may be used in the form of small pieces or in the form of a plate-shaped object or the like. Alternatively, the small pieces and the plate-shaped object (molded product) may be used at the same time. Here, the plate-shaped object has upper and lower surfaces that are circular, elliptical, polygonal, irregular, etc., when viewed from above and below, and has a thickness that is shorter than the length of the upper and lower surfaces when viewed from the side. The plate-shaped treatment material can be obtained, for example, by cutting a pulp block (compressed product) available from a paper factory to an appropriate thickness. This plate-shaped treatment material can be used as is for treating waste eggs. The waste egg treatment material configured as a plate-shaped object has a stable shape and is easy to handle. As a result, it is possible to stack waste eggs on the treatment material in a flexi-con bag, improving the treatment efficiency. When the waste egg treatment material is used in the form of small pieces, the treatment material can penetrate into the gaps between the waste eggs in the flexi-con bag, making it possible to efficiently absorb the egg liquid generated from the waste eggs.

[0039] The size of the waste egg treatment material configured as a plate-like object can be appropriately set according to the shape and size of the flexible container bag into which the waste eggs are put, how the treatment material is used, etc. For example, when the treatment material and waste eggs are alternately stacked 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 to 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 the capacity of the bag is full, and waste eggs can be efficiently treated.

[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 3 Even if the specific gravity is above this, when the pulp is compressed and formed into a block (slab-shaped object), its specific gravity will be 1.1 or more. In this way, if the specific gravity of the slab-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 FIBC bag together with the waste eggs. There is no particular upper limit on the specific gravity of the treatment material, but since pulp is a raw material derived from plants, in reality the specific gravity will not exceed 1.7 even if it is compressed and formed with a large force.

[0041] [Method of Disposal of Discarded Eggs] The discarded egg treatment method of the present invention is carried out using the above-mentioned treatment material for discarded eggs. The discarded egg treatment method of the present invention includes an arrangement step of arranging 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 discarded egg treatment method of the present invention, discarded eggs (egg liquid) that contain a large amount of protein that cannot be fully absorbed by water-absorbent polymers can be efficiently absorbed and treated by the treatment material.

[0042] <Placement process> In the placing step, the pulp (treatment material) placed inside the flexible container bag may be in the form of granules or flakes, but as described above, it is preferable to use a plate-like material formed to match the shape and size of the flexible container bag. The properties of the pulp are as described above, and a detailed description will be omitted.

[0043] <Input process> In the loading process, discarded eggs are loaded onto the treatment material. The discarded eggs may be loaded with their shells still attached. In this case, the shells of the discarded eggs will crack and 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. In addition, because the discarded eggs can be processed as they are even if their shells are cracked, processing is not time-consuming and work efficiency is improved.

[0044] <Alternate operation> It is preferable that the above-mentioned arrangement step and the introduction step are repeated alternately. This allows the discarded eggs to be stacked in the FIBC bag, improving the processing efficiency. When a general cylindrical FIBC bag (diameter 1100 mm, height 1100 mm, capacity 1000 L) is used, the number of layers of discarded eggs can be 2 to 10 layers with the treatment material sandwiched between them, but considering the appropriate thickness of the treatment material, it is preferable to have 4 to 5 layers. In addition, when performing the arrangement step and the introduction step alternately, it is preferable that the arrangement step and the introduction step are performed 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 by the treatment material. As a result, even if the discarded eggs are introduced until the capacity of the FIBC bag is full, no liquid leakage occurs, improving the processing efficiency.

[0045] <Post-processing> When the FIBC bag is full, it is buried in the ground as it is for post-treatment. According to the method for treating discarded eggs of the present invention, the treatment material is made mainly of pulp, so when buried in the ground, it naturally decomposes, resulting in a small load on the environment. In addition to burying in the ground, it can also be incinerated. EXAMPLES

[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 explained below.

[0047] [Fluidity Verification Test 1] If the treatment material that has absorbed the egg liquid from discarded eggs exhibits high fluidity, the treatment material may flow together with the egg liquid and accumulate at the bottom of the flexible container bag, possibly leaking out of the flexible container bag. Therefore, in order 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 carried out according to the following procedure. (1) Weigh out the egg liquid from three raw eggs, which are assumed to be discarded as the target for processing, and put it into a mixer (Waring Stand Mixer WSM7Q, manufactured by Osaka Chemical Co., Ltd.). (2) 20% of each of the treatment materials (virgin pulp (Example 1), recycled paper pulp (Example 2), and superabsorbent polymer (Comparative Example 1)) based on the weight of the egg liquid was added to the mixer. (3) Start the mixer and mix at 41 rpm for 1 minute to mix the egg liquid with the treatment ingredients. (4) The mixer is stopped and the fluidity of the mixture of egg liquid and processing materials is visually confirmed.

[0048] The following three types of processing materials were used in the fluidity confirmation test 1. The processing materials used in the fluidity confirmation test 2, the stability confirmation test, and the lamination test described below are also the same as those described below. (Example 1) Virgin pulp Seller: Technica LLC Product name: Palsap (agent B) Ingredients: Natural wood pulp (Pinus spp.: 60% by weight, Picea spp.: 38% by weight, Balsam fir: <2% by weight) Bulk density as pulp: 0.39g / cm 3 (2.59cm 3 / g) Specific gravity as block (plate): 1.4 ·Moisture content: 10% by weight (Example 2) Waste paper pulp (recycled paper fiber) Seller: Japan Creative Co., Ltd. Product name: 250kg 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) Highly absorbent polymer Seller: Technica LLC ·Product name: SAP High Spec Ingredients: Polyacrylic acid polymer

[0049] The results of the fluidity confirmation test 1 are shown in FIG. 1. In the test of Example 1, in which virgin pulp was used 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, in which recycled paper pulp was used 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, in which a highly water-absorbent polymer was used 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. In this way, it was shown that the treatment material made mainly of pulp is very useful for the treatment of discarded eggs.

[0050] [Fluidity Verification Test 2] Next, in order to confirm the appropriate amount of treatment material to be added to the egg liquid for the virgin pulp, which was effective in suppressing the fluidity of the treatment material that had absorbed the egg liquid, fluidity confirmation test 2 (Examples 3 to 5) was conducted according to the following procedure. (1) Weigh out the egg liquid from three raw eggs to be discarded, and pour it into a mixer (Waring Stand Mixer WSM7Q, manufactured by Osaka Chemical Co., Ltd.). (2) The treated material (virgin pulp) is added to the mixer in the following ratios relative to the weight of the egg liquid: 20% (Example 3), 15% (Example 4), and 10% (Example 5). (3) Start the mixer and mix at 41 rpm for 1 minute to mix the egg liquid with the treatment ingredients. (4) Stop the mixer and after 20 minutes, visually check the fluidity of the mixture of egg liquid and processing materials.

[0051] The results of the fluidity confirmation test 2 are shown in FIG. 2. The test of Example 3, in which 20% virgin pulp was mixed with respect to the weight of the egg liquid, was conducted under the same conditions as Example 1, and no fluidity was observed in the mixture of the egg liquid and the treatment material. In the test of Example 4, in which 15% virgin pulp was mixed with respect to the weight of the egg liquid, almost no fluidity was observed in the mixture of the egg liquid and the treatment material, although this was not as good as that of Example 3. In the test of Example 5, in which 10% virgin pulp was mixed with respect to the weight of the egg liquid, some fluidity was observed in the mixture of the egg liquid and the 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 mix the treatment material at 10% or more by weight of the egg liquid.

[0052] [Stability confirmation test] When transporting flexible container bags containing discarded eggs, it is necessary that the contents are stable and that no liquid leakage occurs. Therefore, in order to confirm the stability of the treatment material that absorbed the egg liquid, a stability confirmation test (Examples 6 and 7) was carried out according to the following procedure. (1) Place a cone container (upper diameter 70 mm, lower diameter 100 mm, height 60 mm) on the table (diameter 300 mm) of a mortar flow tester (C-206, Nishinippon Testing Machine Co., Ltd.). (2) A corn container is filled with a mixture of egg liquid (from five raw eggs) prepared in the same manner as in Fluidity Confirmation Test 1 and treated material [virgin pulp (Example 6), recycled paper pulp (Example 7)]. (3) After carefully removing the cone container, the mortar flow tester is vibrated up and down 50 times and any change in the shape of the mixture is visually confirmed. (4) Remove the mixture from the table, allow kitchen paper to absorb the moisture on 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 the egg liquid and the treatment material after the mortar flow test, and it was stable. In addition, the amount of water syneresis was only 0.04 g, and there was no need to worry about 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 the egg liquid and the treatment material after the mortar flow test was slightly distorted, but it was relatively stable. In addition, the amount of water syneresis was kept to a small amount of 2.15 g, and there were few practical problems. In this way, it was shown that treating discarded eggs with a treatment material mainly made of pulp is very useful because it is stable when transported in a flexible container bag and there is no problem with liquid leakage.

[0054] [Lamination test] When discarded eggs are put into a FIBC bag, it is required to contain as many discarded eggs as possible while preventing leakage of the egg liquid. To achieve this, it is necessary to stack the discarded eggs in multiple layers. Therefore, in order to confirm the capacity of the FIBC bag to contain discarded eggs, a stacking test (Examples 8 and 9) was carried out according to the following procedure. (1) Approximately 55 g of treatment material [virgin pulp (Example 8), recycled paper pulp (Example 9)] is placed in a container to form a treatment layer (first layer). (2) Three to four chicken eggs (50 to 70 g each) are placed on top of the treatment layer with the shells on to form an egg layer, and approximately 55 g of treatment material is placed on top of that to form the next treatment layer (second layer). (3) Repeat the above step (2) to form up to the fifth layer. (4) Visually check the condition of layers 1 to 5.

[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, a phenomenon was observed in which the egg liquid clung to the treatment material to some extent when the eggs cracked during stacking, but there was no severe leakage of the egg liquid or significant flow of the mixture of the egg liquid and the treatment material. In this way, it was shown that the use of a treatment material whose main ingredient is pulp is very useful in terms of improving the processing efficiency, since it allows discarded eggs to be stacked in a flexcon bag while preventing leakage of the egg liquid. [Industrial Applicability]
