The present invention relates to liquid overuse compositions and clarification methods. More specifically, the present invention relates to a method of using beaten refined linter pulp and fibers that are unbeaten or have a low degree of beating in combination in a specific ratio, and to a beating composition containing both pulps in a specific ratio. Traditionally, inorganic natural products such as asbestos, diatomaceous earth, acid clay, china clay, colloidal clay, and zeolite, as well as anthracite, charcoal powder, wood pulp, and sawdust have been used as super-auxiliaries in the manufacturing process of chemical industries such as foods and pharmaceuticals. In addition to organic natural products, inorganic materials and artificial products such as alumina gel, silica gel, and other metal oxide gels have been used. For example, in the sake brewing industry, sake with a high degree of clarity is desired, and for this purpose, asbestos, diatomaceous earth,
Wood pulp has been used. Among these, asbestos is suitable for obtaining the highest degree of clarity and has been used as the main super-aiding agent. The characteristics of asbestos are that it is made up of fine fibers with a diameter of approximately 1 micron, and they intertwine with each other to form a strong overlayer, allowing the removal of minute solid objects.Furthermore, it has little overresistance and can be used to remove overlayers. It has the advantage of being easy to use because it is easy to disintegrate and has good dispersibility during production. On the other hand, it also has disadvantages, such as poor releasability from supporting materials such as cloth or wire mesh, and the inability to incinerate it after use. Recently, asbestos is said to have a negative impact on occupational health, and its use has been restricted. Therefore, the appearance of an excellent super-auxiliary agent to replace asbestos is eagerly awaited in the chemical industry, including food and pharmaceutical industries. Wood pulp has a thick diameter of about 5 to 40 microns, so it is less entangled, and when used in conjunction with activated carbon, charcoal leaks into the liquid, making it unable to perform the same functions as asbestos. Diatomaceous earth has inferior clarity compared to asbestos, and activated carbon is used in combination with other super-aids, so it can be said that none of the existing super-aids can replace asbestos. Recently, sheets of linter pulp have been developed and are being used by some sake brewing manufacturers, and they are starting to attract attention as a super-aiding agent that can replace asbestos. This linter pulp sheet-like product is produced by cooking and whitening linter pulp obtained from cottonseed to produce purified linter pulp, which is then beaten, dried, and made into sheet paper. However, paper-like linter pulp is difficult to disintegrate in water, so some sake brewing manufacturers have installed a special disintegrating machine, filled it with water, immersed the sheet-like linter pulp, and then used it with high-speed rotating blades. After disintegration, the free water is removed, and it is added to the lees and pre-coated in a filter press type pressure filtration machine, etc., and then transferred to the clarification process. In order to use sheet-like linter pulp in this way, it is necessary to install a new disintegrator, which seems to be hindering its widespread use. Next, flaky linter pulp was developed, which is obtained by loosening the fibers and drying them after a beating process. This usage method involves soaking it in water overnight and then loosening it manually or disintegrating it with a stirrer etc., and then removing free water as necessary and re-originalizing it in the same way as paper-like linter pulp. It is used to make lowered sake. Although flaky linter pulp is an improvement over paper linter pulp in that it does not require a dedicated disintegrator, these improvements are not possible because it requires long soaking in water and labor to loosen the fibers afterwards. Highly desired. In addition, wet linter pulp, which is not dried after the beating process but retains a certain amount of moisture, is
Although it is relatively easy to disintegrate, it has not been commercialized because of the risk of contamination with common microorganisms and storage problems. As a result of various research aimed at developing a super-aid to replace asbestos, the present inventor has discovered that it is possible to mix beaten linter pulp with unbeaten or low-beating fibers in a specific range of proportions. As a result, the present inventors discovered that each of them exhibits excessive functions that far exceed those of each of them individually, leading to the completion of the present invention.
That is, the present invention uses linter pulp with an α-cellulose content of 95% by weight or more and a beating degree of 20 to 70.
An overused composition comprising 98 to 50% by weight of linter pulp and 2 to 50% by weight of fibers other than linter pulp and wood pulp with a beating degree of 20 or less, and a liquid characterized in that it is used in combination. This is a clarification method. The linter pulp used in the present invention has an α-cellulose content of 95% or more and a beating degree of 20 to 70. This linter pulp can be produced from linter pulp obtained from cottonseed by a method known per se. In the present invention, the α-cellulose content is generally
98% or more, fiber length is 0.5-1.5mm, and the beating degree is
Preferably, 30 to 55 linter pulp is used. Other fibers used in the present invention are:
Linter pulp that is not beaten or has a beating degree of less than 20 and has a low degree of fibrillation, natural vegetable fibers such as hemp (excluding wood pulp), natural animal fibers such as silk and wool, and nylon. Synthetic fibers and even inorganic fibers such as asbestos are used for this purpose. The composition of the present invention is made by mixing refined linter pulp with other fibers. Both pulps may be mixed in dry or wet form, but wet mixing is more preferable. For wet mixing, add approximately 5 times as much water to a wet linter pulp product that has been beaten to a degree of beating of 20 to 70, and then mix the other fibers to 100 parts of the solid content of the linter pulp. Add 2 to 100 parts to the mixture and mix thoroughly. All can be mixed well within the ratio range described herein. The purpose of mixing and kneading these fibers can be achieved by using conventional methods such as a stirrer, a milling machine, etc. Next, this is made into a sheet or flake form, and when it is made into flakes, the following method is preferred. That is, it may be carried out using a loosening machine, a crushing machine, etc., and there is no need to limit it to a specific device. This is dried to a thickness of about 1 cm or less, with a moisture content of 10%.
Although the drying method is not limited to a specific method, a commonly used drying method at about 60 to 100° C. may be used, but hot air ventilation drying is more efficient. The mixing ratio of beaten linter pulp and other fibers is 98 to 50% by weight of beaten linter pulp and 2 other fibers.
The content may be in the range of ~50% by weight, but it is particularly preferably about 90 to 70% by weight of beaten linter pulp and about 10 to 30% by weight of other fibers. The mixing ratio of both pulps is
Compositions containing less than 2% by weight of other fibers have the disadvantage of being difficult to disintegrate;
A composition containing more than 50% by weight will have poor dispersion stability, toughness, etc., and will not function adequately as an overused composition containing beaten linter pulp. The overuse composition of the present invention can be used in the same manner as conventional super-aids such as asbestos, and the amount used is about the same as asbestos. Furthermore, the present invention eliminates the need to mix the beaten linter pulp and other fibers in advance, and uses a method in which the beaten linter pulp and other fibers are used separately when precoating the overused support material. good. Even in the case of this method, the addition ratio of beaten linter pulp and other fibers is the same as in the above composition. The present invention, in which beaten linter pulp and other fibers are used together in the over-use composition, has much higher functionality than when both pulps are used alone. In other words, linter pulp alone is difficult to disintegrate, and requires a lot of effort to soak in water for a long time and then loosen the fibers.However, this composition only requires soaking in water for a short time and can be used exclusively for subsequent loosening. It is possible to sufficiently disintegrate it using the usual method used for asbestos, without requiring a disintegrator. Furthermore, it has good dispersion stability after disintegration, and can form a more uniform layer than other fibers alone. In terms of overcapacity, the elapsed time is relatively shorter than that of beaten linter pulp, and in addition, the oversurface is strong and there is no need to worry about charcoal leakage when used in combination with activated carbon like with other fibers. The liquid after evaporation was sufficiently clear, and the sensory evaluation of sake etc. was also good. Furthermore, the linter pulp and other organic fibers used in the present invention can be used to incinerate the filtrate cake after filtration, and there is no problem regarding industrial waste.
Moreover, it has advantages such as being inexpensive. Applications of the present invention include alcoholic beverages such as sake, beer, and wine, seasonings such as mirin, vinegar, and soy sauce;
It can be widely used to filter and clarify soft drinks and other liquids. The principle of the present invention can be considered as follows.
In other words, it is thought that the hydrogen bonds in the fine fibers of beaten linter pulp give the paper its toughness and make it difficult to disintegrate into water, but the coexistence of other fibers may disrupt these hydrogen bonds. It is presumed that the disintegration into water is significantly improved as a result of the activation. Next, the present invention will be explained in more detail using experimental examples. The measurement method used in the present invention is as follows. ●Disintegration property After immersing 1 g of the supernatant composition in 20 ml of pure water at room temperature for 1 hour, it is loosened with a metal spatula, and the time taken until the small lumps disappear is measured to judge the difficulty of disintegration property. ●Dispersion stability Make a suspension of 0.3 g of super-aid composition and about 100 ml of pure water, put it in a graduated cylinder with a 100 ml stopper to bring the total volume to 100 ml, mix well, and let it stand at room temperature.
The volume of the sediment after 5 minutes is read and expressed in ml to judge the dispersion stability. ●Overcapacity Diameter 40mm, length 300mm with overcapacity 12.6cm2
A metal overpressure tester is used. Toyo Paper (No.
131, diameter 70 mm), thoroughly suspended a predetermined amount of super-aid (200 g per 1 m2 of super-aid area) in 50 ml of a 25% by weight granulated sugar aqueous solution, and then gently added it to the super-assistant, and then After washing with 50ml of granulated sugar aqueous solution (wt%), pressurized air (160mmHg)
(constant), the pre-coat is over. Next, as a test solution, 0.3 g of activated carbon was added to 300 ml of a 25% by weight granulated sugar aqueous solution, the sufficiently suspended solution was gently added onto the precoat layer, and the mixture was stirred at room temperature.
Flush with pressurized air (160mmHg constant).
During this time, read the liquid volume per minute and plot it on a graph to determine the excess capacity (m 3 /m 2 Hr.). ●Toughness and charcoal leakage test After the above-mentioned overcapacity test, the paper with cake was removed from the sieve machine, the cake was peeled off from the paper, and it was observed whether there were activated carbon particles that had leaked on the paper or not. Evaluate the toughness of the layer. If the precoat layer is weak, it will not be able to withstand the flow rate of the liquid, and the activated carbon particles will pass through the overlayer and adhere to the paper. ●Releasability The releasability is evaluated by observing whether the precoat layer is easily peeled off from cloth, paper, etc. ●Liquid quality: Pass the liquid through a membrane filter (47m/m, TM
-2, 0.47μ diameter), and the quality is judged by the presence or absence of visible foreign matter remaining on the filter. ●Turbidity (clarity) of the liquid The turbidity of the liquid was determined using a Hitachi EPO-B photometer and a galvanometer according to the turbidity measurement method specified by the National Tax Agency. Experimental example 1 Beating treated linter pulp (beating degree approximately 50)
Mix wet product (moisture 70%) and unbeaten linter pulp powder (paper pulp) in various ratios of solid content, add 30 times the amount of water, stir with a spatula, and shake in an Erlenmeyer flask. After mixing evenly, dehydrate using a glass filter. After crushing this to a size of 2 to 5 mm, it is dried with hot air at 80°C for 3 hours to create flaky samples with a moisture content of 10% or less. The overcharacteristics of this sample were measured by the above-mentioned measuring method, and the results are shown in Table 1. 2-50% unbeaten linter pulp powder
The additives have better disintegration,
It has improved peelability and other properties are also comparable. Furthermore, it was superior in terms of dispersion stability, toughness, and turbidity compared to the unbeaten linter pulp powder alone. Experimental example 2 Beating treated linter pulp (beating degree approximately 50)
Samples were prepared in the same manner as in Experiment 1 by mixing a wet product (moisture 70%) and a powdered super-assistant mainly composed of silk fibers in various proportions (weight), and the super-assistance properties were evaluated. The results of the experiment are shown in Table 2. Products to which 2 to 50% of a powdered super-aid agent mainly composed of silk fibers are added have improved disintegration and peelability, and are not inferior in other properties, compared to products without additives. If more than that is added, dispersion stability, toughness, and turbidity will deteriorate.
