Whole cotton seed is the remaining thread after removing the rough surface from cotton (cotton), and some lint is attached to the outside of the thread. The front chamber has high energy (2.3Mcal NEI / kg) content, about 15-17% fat, 15-21% protein, 85-90% TDN (total amount of plasticized nutrients), and 24% crude fiber (26- 31% ADF) has a high nutritional content, and lint wrapped cottonseed is pure cellulose, which is 100% digested by rumen microbes and has a very high feed value (Arieli, A. 1998. Whole cottonseed in dairy cattle feeding: a review.Animal Feed Science and Technology. 72 (1-2): 97-110).

The front cotton thread is characterized by high energy content and crude fiber content at the same time, which is very helpful in increasing the flow rate and normal fat (milk fat) of high-capacity cows. Is increasing. The rough surface attached to the outside centering on the cotton thread is mostly separated from the seed thread in the processing process, but is not completely separated. This results in whole cotton seeds being used as feed for livestock, with a certain amount of lint sticking to the surface of the seed with a hard shelled seed (Beranrd, JK 1999, Performance of Lactating Dairy Cows Fed Whole Cottonseed Coated) with Gelatinized Cornstarch.Journal of Dairy Science. 82: 1305-1309). In this way, the lint attached to the seed surface is entangled with each other and easily agglomerates, causing problems in deteriorating the working environment by making transport and mixing with other feeds difficult in the feed manufacturing process (Moreira, VR, Satter, LD and Harding, B. 2004. Comparison of Conventional Linted Cottonseed and Mechanically Delinted Cottonseed in Diets for Dairy Cows.Journal of Dairy Science. 87: 131-138).

The present inventors have developed a technology for coating the front chamber using an appropriate mixture of luxurious starch and lignosulfate, which have been luxuriously treated with a binder (Korean Patent Registration No. 10-1337883; a front chamber for coated livestock feed using a binder) Method of manufacturing). However, when the starch used as a binder in the above method is mixed with water, it is not evenly mixed with the whole cotton thread due to the unique stickiness, and entangles and clumps together, resulting in reduced production efficiency. Moreover, since luxurious starch is more than twice as expensive as ordinary starch, it has the disadvantage of increasing production costs and deteriorating economic efficiency, as well as having the disadvantage of limiting the choice of coating agents. However, in the above method, since the purified water uses 5 to 30% (w / w) of the weight of the cotton thread to form the whole cotton thread, drying is essential, and in order to improve the coating strength, the starch consumption must be maintained at a certain level. As the amount of use increases, the amount of purified water also increases. For this reason, the largest proportion of the drying cost among manufacturing costs (Laird, W., TC Wedegaertner, and TD Valco. 1997.Coating cottonseed for improved handling characteristics.Proc. Belt wide Cotton Conf.New Orleans, LA 1599-1602 ).

In addition, the present inventors have developed a method of manufacturing a high-strength coated animal feed chamber for high-intensity using high-viscosity starch by removing the germination function of the battery chamber by using high-temperature and high-pressure steam, and then pregelatinizing the starch in the manufacturing process. (Korean Patent No. 10-1551333). Specifically, (1) a first step of removing the lint from the battery compartment; (2) a second step of preparing a mixture by adding a coating agent and purified water to the battery compartment and mixing; (3) a third step of spraying high temperature and high pressure steam to the mixture to remove the germination function while stirring the mixture, and preparing a binder by gelatinizing the mixed coating agent; (4) It relates to a manufacturing method for manufacturing a coated cotton wool for livestock feed comprising a fourth step of cooling the binder without drying.

In addition, the present inventors omitting the method of manufacturing the front surface chamber, characterized in that the step of coating the surface of the front surface chamber, that is, (1) a first step of removing lint from the front surface chamber; (2) a second step of manufacturing a hydrated battery compartment by adding purified water to the battery compartment; (3) a third step of removing germination function while stirring the mixture by spraying high temperature and high pressure steam to the water-containing battery compartment; (4) Developing a manufacturing method for manufacturing an uncoated livestock feed cell chamber comprising a fourth step of drying and cooling the front warp chamber (Korea Patent Registration No. 10-1824133); A new relatively small step of producing a feed front chamber, in which the lint removal step and the coating step of the front side chamber are omitted, that is, (1) a first step of manufacturing a hydrated front chamber by adding purified water to the front chamber; (2) a second step of removing germination function while stirring the mixture by applying high temperature or spraying high temperature and high pressure steam to the hydration chamber; (3) There has been developed a method of manufacturing a non-coated lint-containing cell surface for animal feed containing a third step of drying and cooling the cell-side chamber (Korean Patent Registration No. 10-1824132).

However, although the above technologies have eliminated the drying process that consumes the most energy, the germination function must be removed through the process of using high-temperature and high-pressure steam for no drying. It is necessary to develop technologies for savings.

Therefore, in the present invention, after performing the primary coating process by the existing patented technology (Korean Patent Registration No. 10-1337883), the free surface water of the primary coated cell surface is rapidly increased through additional secondary coating. By discovering a method of reducing and improving storage, (1) through the development of a manufacturing method that can completely omit the energy-intensive drying process after coating, simplification of the production process and significantly reduced production cost (2) It is confirmed that the problem of the existing manufacturing process is solved by using a new method of manufacturing a front-surface chamber that exerts unexpected and advantageous effects by those skilled in the art, such as fundamentally blocking / resolving various problems that may occur in the long-term distribution process by improving storage. , The present invention was completed.

An object of the present invention is to improve the storage and quality during the coating process of the front surface, the secondary coating material to improve the storage after the first coating by using a molding agent added with gelatinized starch and sodium chloride (NaCl) as coating agents to improve the storage and quality. It provides a method of reducing the free water of the cotton thread surface in a short time by using mineral oil and bentonite, thereby providing a method of manufacturing a coated cotton thread without a drying process.

Specifically, the present invention (1) a first step of removing the lint from the battery compartment; (2) a second step of preparing a mixture by adding and mixing a storage-enhancing agent such as purified water and sodium chloride (NaCl) into the front chamber; (3) a third step of mixing a mixture of the two steps with a primary coating agent such as gelatinous starch to prepare a primary coating material to bind the coating agent; (4) a fourth step of preparing a secondary coating by secondary coating the primary coating by introducing a secondary coating agent such as mineral oil and bentonite; (5) It provides a method of manufacturing a double-coated non-dried coated cotton yarn with improved storage without drying, including a fifth step of cooling the secondary coating of step 4 without drying.

In the first step of the manufacturing method, the battery compartment is characterized in that it is an imported or domestic battery compartment from Australia, the United States, China, India, Pakistan, Brazil, Turkey, Uzbekistan, Greece, and Vietnam. In this step, it is characterized in that the amount of lint is finally removed in an amount of 1 to 10% (w / w), preferably 1 to 5% (w / w), relative to the weight of the battery compartment.

The purified water used to increase the coating power in the second step is characterized by adding and mixing purified water having a weight of 1 to 20% (w / w), preferably 3 to 9% (w / w), compared to the total weight of the battery compartment. do.

In the second step, the reason for using purified water in the step of mixing purified water in the front chamber is to infiltrate the lint attached to the seed chamber, and then stir it for a certain period of time to easily separate the clumped lint and form it into the center of the seed chamber. This is the purpose. If the mixing ratio of the mixture of the whole cotton thread and the purified water is less than the above-mentioned range, the lint is difficult to separate and the coating strength is lowered. If it is more than this, the drying process is additionally required, which may cause economical deterioration.

In addition, in the second step, the storage enhancer such as sodium chloride (NaCl), magnesium chloride (MgCl), and potassium chloride (KCl) is mixed with purified water and added to 1-15% (w / w) by weight of purified water, preferably Is a 3 to 10% (w / w) weight of the storage enhancer is mixed, and since the amount of purified water is variable depending on the moisture content of the front chamber, the concentration of the storage enhancer compared to the final purified water is 1 to 10% (w / w) , Preferably, it is preferable to add 3 to 8% (w / w). It is characterized in that the purified water added in the second step of the manufacturing method has a stabilization period for 1 to 6 hours, preferably 2 to 4 hours, so that the moisture spreads evenly to the center of the final product.

In addition, in the third step, the primary coating agent is gelatinous starch, lignosulfate, gelatins, molasses, corn starch, tapioca starch, wheat starch, rice starch, potato starch, sugars, CMS (Condensed Molasses Fermentation Solubles), molasses , One or more primary coating agents selected from the group consisting of corn flour, tapioca flour, wheat flour, rice flour and cellulose, or the like, or a combination thereof.

 In the third step of the manufacturing method, when the primary coating agent is used in combination, the relative weight mixing ratio of the gelatinous starch and lignosulfate is 0.5 to 10: 1 relative to the gelatinous starch and lignosulfate combination. (w / w), preferably 1 to 8: 1 (w / w).

In the third step of the manufacturing method, the primary coating agent is added in an amount of 0.01 to 30%, preferably 0.1 to 10% of the primary coating agent (w / w), relative to the total weight of the total cotton thread. Here, the amount used may be different depending on the type of the primary coating agent. In the case of gelatinous starch, 2 to 5% (w / w), gelatins 0.5 to 2% (w / w), lignosulfate In the case of, it is preferable to use an amount of 1 to 3% (w / w). However, when the binder is used by mixing at least one or more, the amount of use can be controlled.

In the third step of the manufacturing method, in terms of the input method of the primary coating agent, about 1/100 to 1/5 (w / w), preferably about 1/50 to 1/10 (w) / w) It is preferable to stir while uniformly dividing the amount several times and continuously inputting it.

When the coating agent is evenly dispersed and bound to the cotton yarn absorbing moisture, not only the coating effect is large, but also the amount of the coating agent used can be reduced, which increases the economic effect. The principle of using the coating material is to keep the lint adhered to the surface of the cottonseed thread tightly attached to the surface of the cottonseed thread to maintain a constant shape.

In the present invention, since the method of injecting the primary coating agent (binder) is a very important factor in maximizing the effect of the present invention, it is preferable to divide the binder as many times as possible so as to be evenly dispersed. If the binder to be added is added irregularly, there is a fear that the binder may be irregularly bound to the cotton yarn mixed with the purified water in advance. When the binder is evenly dispersed and bound to the cotton yarn absorbing moisture, not only the binding effect is large, but also the amount of the binder used can be reduced, which increases the economic effect.

In the above 4th step, the 2nd coating material used for the 2nd coating of the 1st coating 1st coating in the 3rd step is mineral oil, essential oil, soybean oil, corn for oil film coating effect One or more vegetable oils consisting of oil, canola oil, olive oil, sunflower oil, coconut oil, palm oil, and cottonseed oil, and one or more clays consisting of bentonite, montmorillonite, geolite, illite, and silica gel groups with hygroscopic effects Mineral materials are added individually or in mixture, respectively, and mineral oil is preferably added in an amount of 0.1 to 2% (w / w), preferably 0.2 to 0.6% (w / w), compared to the weight of the entire battery compartment. Bentonite is preferably added in an amount of 0.1 to 1% (w / w), preferably 0.2 to 0.6% (w / w), relative to the weight of the battery compartment. Bentonite has a hygroscopic effect and was used to rapidly reduce free water, and mineral oil was used for a film coating effect to improve storage.

In the fifth step of the manufacturing method, it is characterized in that the secondary coating is cooled without drying using heat. More specifically, it is characterized in that the moisture content of the final coating product is adjusted to the amount of purified water in the second stage in consideration of the moisture content of the cotton yarn in the first stage and is maintained properly without a drying process. , 10 to 18%, preferably 11 to 15% of the moisture content of the final product. The cooling time using air at room temperature in the mixture of the battery compartment and the coating agent is preferably 1 to 60 minutes, preferably 10 to 30 minutes.

In addition, the present invention (1) the first step of removing the lint in an amount of 1 to 10% (w / w) of the amount of lint relative to the weight of the battery compartment in the battery compartment; (2) Sodium chloride (NaCl) containing purified water was added to purified water by adding 1 to 24% (w / w) sodium chloride (NaCl) to purified water, and then purified water containing sodium chloride (NaCl) was added to 1 to 15% by weight a second step of preparing a mixture by mixing w / w); (3) 0.1 to 30% by weight (w / w) of corn starch, tapioca starch, wheat starch, rice starch and potato starch in the mixture; Sugars, CMS (Condensed Molasses Fermentation Solubles), molasses; Corn flour, tapioca flour, flour, rice flour; And a third step of preparing a primary coating by mixing one or more coating agents selected from the group consisting of cellulose alone or in combination. (4) Secondary by adding 1 to 2% (w / w) mineral oil to the total weight of the front chamber and 0.1 to 2% (w / w) bentonite to the primary coating alone or in combination A fourth step of preparing a coating; (5) Storage performance is improved without a drying process including a fifth step of preparing a final coating product having a final moisture content of 10 to 17%, preferably 11 to 15%, without drying the secondary coating. It provides a manufacturing method for manufacturing a coated cotton yarn for coated animal feed.

Free water, as defined herein, is generally divided into free water and fixed water, and free water is water that can be easily used by microorganisms. It means that it exists in the form and then transforms into the form of fixed water as it enters the cells of the feed.

 Therefore, the present invention provides a double-coated battery compartment manufactured by the manufacturing method according to the present invention.

The coated all-cotton yarn produced by the manufacturing method according to the present invention is a simplified manufacturing process as compared with the conventional coated cotton yarn, the coating power is the same or superior and the storage performance is improved and there is no drying process using heat. According to the production, there is a feature that the effect of reducing production costs is very large.

As described above, the method for manufacturing a coated cotton yarn through double coating while enhancing the storage property of the coated cotton yarn according to the present invention not only simplified the existing coating cotton yarn manufacturing process, but also required steam treatment to produce the coated cotton yarn without drying.

Hereinafter, the present invention will be described in more detail based on the following examples and experimental examples.

However, the following examples and experimental examples are only for illustrating the present invention, and the scope of the present invention is not limited to them.

Comparative Example 1. Method for manufacturing coated cotton yarn for livestock feed using binder (Korea Patent Registration No. 10-1337883)

This comparative example was prepared by the method for manufacturing a coated cotton yarn for livestock feed using the binder described in Example 1 of Korean Patent Registration No. 10-1337883 to prepare the battery cotton yarn of Comparative Example 1 to be used as Comparative Example 1 for the following experimental example. Did.

 Using a stirrer (5m3) (CML-200, Korea) equipped with a hot air supply device (self-produced, Celltech Co., Ltd. Korea) that supplies hot air at the desired temperature, and a panel mounted on the outside of the rotating shaft. It was carried out.

 First, 200 kg of Australian cotton wool (Cargill Australia Limited, Australia) was added to a stirrer and 10 liters of purified water was added, followed by stirring. At this time, the stirring speed was 30 rpm and stirred for 10 minutes to confirm separation of cotton yarn. And, as a binder, 4 kg of corn starch (suprex corn, FFA, Switzerland) was divided into 200 g each, and the mixture was continuously stirred while being uniformly added at intervals of 5 minutes. The hot air blower device was started immediately after the injection of the binder was finished. At this time, the hot air temperature was 100 ℃, and the operation time was about 30 minutes. The moisture content of the dry cell room was measured to be 10.5%, and was used as Comparative Example 1 for comparison in the following Experimental Example.

Comparative Example 2 Method for manufacturing coated cotton yarn with germination function removed (Korea Patent Registration No. 10-1551333)

This comparative example was prepared by using the method for manufacturing a coated cotton yarn having the germination function removed in Example 4 of Korean Patent Registration No. 10-1551333, and using it as a comparative example 2 for comparison of the following experimental example. Did.

1-1. Manufacturing example of the front surface room with the lint removed

 The ratio of the lint to the weight of the front chamber was first measured. The entire cotton yarn used for manufacturing was made in the United States (MOTU0796660, Feedwill, Korea) and made in Australia (UACU8445073, Feedwill, Korea).

The front chamber was dried for 24 hours in a 105 ° C dry oven (JSON-050, JCR, Korea) and used in the experiment. In a fully dried front chamber, 95% purity of H ₂ SO ₄ (Daejung chemicals & metals Co. LTD, Korea) was treated at a rate of 100 ml per kg of the fully dried front chamber to dissolve the lint, wash with water, and then dry ( The weight ratio was calculated by calculating the weight ratio at 105 ° C., 24 hours (Khan, NU, KB Marwat, G. Hassan, Farhatullah, S. Batool, K. Makhdoom, W. Ahmad and HU Khan. , 2010. Genetic variation and heritability for cotton seed, fiber and oil traits in GOSSYPIUM HIRSUTUM L. Pak. J. Bot., 42 (1): 615-625).

 The ratio of lint to weight in the U.S. front yarn was 12.8 ± 0.4 (w / w), and in the U.S. front yarn was 7.5 ± 0.3 (w / w). Compared to Australian cotton wool, US cotton wool had a higher lint ratio of 5.3% (w / w).

It was manufactured using a lint remover (MR114D, SDMT, China) capable of removing the desired degree of lint. When the ratio (weight) of the lint compared to the front cotton room made in the United States was 100, the lint was removed in various proportions while increasing the lint removal rate in 10% increments. When the lint removal rate was 70% (weight) or more, the black part of the seed chamber inside the front chamber was exposed to the outside and showed a tendency to appear black. It was confirmed that the lining removed by removing the lint at a level of 50% (weight) was an excellent proportion of lint being removed while maintaining the color of the front panel.

2-2. Manufacture of all cotton room with germination ability removed

It was carried out as follows in order to manufacture the front surface chamber with the germination function removed. Steam was applied to an American-made front room using a steam generating device (STE2600, Sangnok Electronics, Korea), where the temperature was 120 ° C and the pressure was 6 kg / cm 2. Steam was prepared in increments of 1 minute and up to 10 minutes. In order to measure the germination rate of the steamed front surface for each time zone, 50 steamed front chambers for each treatment area were placed in the germination phase (120 mm × 115 mm), and incubator in a dark condition at 25 ° C. (JSGI- 100T, JS Research, Korea). Germination was observed and recorded every 24 hours for 2 weeks. In the steam-free treatment group, germination proceeded from the 3rd day of culture, and a total of 87% germinated during 2 weeks. A 1 minute steam treatment treatment resulted in 13% of germination over two weeks. All treatments steamed for more than 2 minutes did not germinate.

2-3. Preparation of luxurious starch with improved viscosity by steam treatment

In general, when starch is heated with water, the starch is gelatinized to form a transparent or milky white colloidal solution with a very high viscosity (Lee Boo-Yong, Mok-Cheol Kyun, Cheol-Ho Lee. 1993. Comparison of endothermic pears of starch by DSC and gelatinization by enzyme analysis) Korean J. FOOD SCI.TECHNOL. Vol. 25: 400-403.).

 It was carried out using corn starch (C0022, Samyangsa, Korea) used as a coating agent. Corn starch needs more than 65% moisture to be sufficiently luxurious (Wang et al., 1991, experimental analysis and computer simulation of starch-water interaction during phase transition, J. Food Sci, 56 121).

 In order to measure the degree of gelatinization according to the steam treatment, starch and water suspension were prepared so that the weight ratio of corn starch and distilled water was 35:55 to a level of 65% moisture.

  The starch suspension was put 100 ml into a 500 ml Erlenmeyer flask with branches below, and a steam apparatus at 120 ° C. was put into the lower portion of the Erlenmeyer flask using a steam generating device (STE2600, Sangnok Electronics, Korea). At this time, by inserting a magnetic stick (magnetic stick) inside the Erlenmeyer flask, the steam device was added while stirring. A total of 10 different types of steam treatments were prepared by varying the steam input time from 1 minute to a maximum of 10 minutes to prepare variously starch suspensions.

 After rapidly freezing (-70 ° C) to measure the degree of gelatinization of various prepared starch suspension samples, freeze-drying using a freeze dryer (Ilshin Co., Korea) (operating conditions:-50 ° C, 1.33 Pa ). Each lyophilized sample was powdered and passed through a standard body (100 mesh; 150 µm) to use a solid content having a constant particle size as a measurement sample.

 20 mg of the powder sample was placed in a 50 ml centrifuge tube, and 5 ml of distilled water was added and dispersed, and then amylase solution (a-amylase solution (Sigma, A3306, USA)) was added to each tube; 20.1 units / g solid, acetate buffer, pH 4.5] 25 ml was added and reacted at 40 ° C for 1 hour. After the reaction, 2 ml of 25% trichloroacetic acid (Wako, 204-02405, Japan) was added to stop the reaction, and centrifugation (16,000 × g, 5 min) was performed with a centrifuge (16,000 × g, 5 min) to obtain a supernatant. Degrees were measured.

 Take 0.5 ml of the supernatant, dilute it in a suitable distilled water test tube at 550 nm so that the absorbance value is in the range of 0.1 to 0.9, put it in a test tube, mix it with 1.5 ml of DNS reagent, react for 5 minutes in boiling water, and put it in ice water for room temperature. After cooling by using a spectrometer (UV-Vis spectrophotometer, S-100, Sinco, Korea), absorbance was measured at 550 nm. Reducing sugar was calculated using a calibration curve calculated using pure glucose (glucose, G0350500, Sigma, USA).

 In order to calculate the specific gelatinization degree, by performing steam for 30 minutes in the same manner as above, the gelatinization degree was calculated using the ratio of the reducing sugar for each time period compared to the reducing sugar of the fully gelatinized starch. When the steam was not treated in the battery compartment, the degree of gelatinization was about 26%, and when steaming for more than 2 minutes at a temperature of 120 ° C and a pressure of 6 kg / cm2, the degree of gelatinization increased to 73%, forming a colloid to improve viscosity. It was confirmed that the prepared luxury starch was prepared.

2-4. Manufacture of coated cotton thread with germination function removed

 In order to manufacture the coated cotton yarn having the germination function removed, the Australian cotton wool yarn (UACU8445073, Feedwill, Korea) was removed using a lint remover (MR114D, SDMT, China) as in Example 1 to remove 2% of the lint from the weight. The prepared front-surface chamber was prepared as 'de-linted front-surface chamber'. In the same manner as in Example 2, the 'de-linted battery compartment' was steam-treated for 2 minutes at a pressure of 6 kg / cm 2 at 120 ° C. using the device for generating steam (STE2600, Sangnok Electronics, Korea). An all-surface chamber was prepared and was referred to as a 'pre-emergence removal all-surface chamber'. In the same manner as 2-3 above, corn starch (C0022, Samyangsa, Korea) was used to prepare a starch suspension having a moisture level of 65% and then using steam generating device (STE2600, Sangnok Electronics, Korea) at 120 ℃, pressure Steamed under a condition of 6 kg / cm 2 for 2 minutes to prepare a luxurious starch with a high viscosity to make it 'Gelatinized starch.' 100 kg of 'Gerlatinized starch chamber' was added to a stirrer (DDK-801M, Daedong, Korea) and 5 kg of purified water was added. After stirring for 5 minutes, forming the 'emergence function-removing battery compartment', and then adding 5.7 kg of 'Gelatinized starch', stirring for 5 minutes to prepare a coated battery-separated chamber with germination function removed and used as Comparative Example 2 for the following experimental example Did.

Example 1. Preparation of the lining-free battery compartment

In this example, the moisture content of the U.S.-made front chamber was measured in order to manufacture the front-side chamber with lint removed.

Moisture measurement was performed by drying for 3 hours in a 130 ° C dry oven (JSON-050, JCR, Korea) according to AOCS Aa3-38 (American Oil Chemists's Society) analysis. The moisture content of the battery compartment used in this experiment was 9.8% (w / w). The content of lint adhered to the front surface of the front chamber is treated with 95% purity H ₂ SO ₄ (Daejung chemicals & metals Co. LTD, Korea) in a fully dried front chamber at a rate of 100 ml per kg of the front chamber. After melting, washed with water and dried (105 ℃, 24 hours), the weight ratio was calculated to obtain the lint weight ratio compared to the front room (Khan, NU, KB Marwat, G. Hassan, Farhatullah, S. Batool, K. Makhdoom, W. Ahmad and HU Khan., 2010. Genetic variation and heritability for cotton seed, fiber and oil traits in GOSSYPIUM HIRSUTUM L. Pak. J. Bot., 42 (1): 615-625). The ratio of lint to weight in the U.S. front room was 11.4 ± 0.3 (w / w). The front side room production in which the lint adhered to the front surface of the front side room 50% was removed was manufactured using a lint remover (MR114D, SDMT, China).

Example 2. Preparation of coated cotton yarn with improved storage ability with sodium chloride (NaCl) added

A coated cotton yarn with improved storage was manufactured using the battery cotton yarn prepared in Example 1. Considering 9.8% (w / w) of moisture content of the cotton yarn with 50% lint removed, purified water for 100kg coating was mixed with 5.7kg so that the final coating cotton yarn had a moisture content of 14.5%, and starch as a coating material (Suprexcorn , FFA) 2.0kg was mixed using a mixer (DKM-250Food, Daekwang Machinery). At this time, the concentration of sodium chloride (NaCl) in purified water was varied to 0, 2, 4, 6, 8% (w / w) and used in the preparation of coated cotton yarn after pre-production.

Example 3. Double coated non-dried coated cotton yarn manufacturing example (FIG. 1)

A secondary coated cotton yarn was prepared using the primary coated coated cotton yarn prepared in Example 2. In Example 2, the NaCl concentration of purified water was 4%, and the primary coating cotton thread was prepared in the same manner as in Example 2, 200 kg. 0.4% mineral oil (PCF-S, Carls NBT) and 0.4% (w / w) Bentonite (FFA) mixed with a weight of 0.4% (w / w) by weight in the cell surface room coated with 4% sodium chloride (NaCl) (DKM-250Food, Daekwang Machinery) was mixed well for 5 minutes. At this time, mineral oil was divided and sprayed several times with a spray, and the total amount of bentonite was divided and added three times.

Experimental Example 1. CO by level of sodium chloride (NaCl) addition ₂ Generation measurement

In order to measure the amount of CO ₂ generated by the level of sodium chloride (NaCl) addition, the method described in the existing literature was applied to perform the experiment as follows (Korean Patent Publication No. 10-2016-0011967).

Since the mold and grown under the presence of oxygen discharging the CO ₂ generation amount of CO ₂ is used as an indirect measure of the growth and division of the mold.

In the CO ₂ generation experiment, the concentration of sodium chloride (NaCl) in a 1 liter glass bottle (BT1050-1000, New International Science) was adjusted to 0, 2, 4, 6, and 8%. Difco) was sterilized with an autoclave (autocalve, HK-AC200 Korea Integrated Equipment Manufacturing Co., Ltd.) at 135 ° C for 20 minutes, then weighed 500 ml, and then put 20 g of a regular front chamber and mixed well and sealed. A CO ₂ detection tube (CO ₂ 2H, Gas tech) was mounted on the top of the Pyrex bottle to measure the amount of CO ₂ generated. The Pyrex bottle was incubated at 35 ° C in an incubator (JSGI-100T, JS Research, Korea) to observe the amount of CO ₂ generated. In the treatment group without sodium chloride (NaCl), the amount of CO ₂ was continuously generated more than 10% even after 48 hours. In all treatment groups in which sodium chloride (NaCl) was added at a level of 2 to 6%, the amount of CO ₂ generated at 12 hours of culture was 0.5%, and in treatments where 4% or more was added, 2 to 2.2% of CO ₂ was added at 36 hours of culture. CO ₂ did not occur after 48 hours. In the 2% sodium chloride (NaCl) addition group, the amount of CO ₂ generation decreased by 50 ~ 75% compared to the control. Sodium chloride (NaCl) added to remove mold generation was found to be suppressed by 80 to 90% or more of CO ₂ generation at the addition of 4% or more, and the optimum treatment level was 4 because there was no difference in treatment over 4%. % Level (Table 1).

Experimental Example 2. Measurement of the number of days of mold development by sodium chloride (NaCl) addition level

For the primary coated coated cotton yarn prepared in the above example, an experiment was performed as follows by applying the method described in the literature to measure the number of days of mold development (Korean Patent Publication No. 10-2016-0011967).

In Example 2, in order to measure the number of days of mold development for the primary coated coated cotton yarn prepared by sodium chloride (NaCl) concentration, the moisture content of the coated cotton yarn was 18% during the primary coating, which measures the number of mold occurrence days. This is to shorten the period. After 10 g of each of the primary coated coated cotton thread was placed in a petri dish, the number of days of mold growth was observed while culturing at 35 ° C. in a culture device (JSGI-100T, JS Research, Korea). At this time, a beaker containing 1 liter of distilled water was placed in an incubator (JSGI-100T, JS Research, Korea) to maintain a constant relative humidity. The number of days of mold development was defined as the point at which mold was generated in 5 or more coated cotton yarns. In the control without sodium chloride (NaCl), the fungus occurred on the 12th day, and on the 4% sodium chloride (NaCl) treatment, the 17th day, and the sodium chloride (NaCl) concentration increased. .

Experimental Example 3. Measurement of the number of mold occurrence days of the double coated cotton yarn

In order to measure the number of days of mold development for the secondary coated cotton yarn prepared in the above example, an experiment was performed as follows by applying the method described in the literature (Korean Patent Publication No. 10-2016-0011967).

In the same manner as in Example 2, 100 kg of the primary coated coated cotton yarn was prepared in the same manner as in Example 3. In the first coating, 4% sodium chloride (NaCl) was used as the purified water, and the moisture content of the coated cotton yarn was set to be 18%, to shorten the measurement period of the number of days of mold development. In the second coating, mineral oil and bentonite were prepared by adding 0.4% (w / w) of cotton yarn weight, respectively. As a control, it was set as a coated cotton thread without primary coating after primary coating with purified water without sodium chloride (NaCl) added. The method for measuring the number of days of mold development was measured in the same manner as in Experimental Example 2. The number of days of mold development in the control group using normal purified water and without double coating was 14 days, and the number of days of mold development in the treatment using 4% sodium chloride (NaCl) purified water and mineral oil and bentonite at a level of 0.4% (w / w) each There is 22. In this example, after the first coating with 4% sodium chloride (NaCl) purified water, it was confirmed that the number of days of mold development can be delayed by about 8 days after the second coating using mineral oil and bentonite (Table 3).

Experimental Example 4. Water activity measurement experiment

 In order to measure the water activity (Water activity) was applied to the method described in the existing literature was carried out the experiment as follows (Korean Journal for Food Science of Livestock Vol 27, No. 3, pp.290 ~ 298).

In the same manner as in Example 2, 100 kg of the primary coated coated cotton yarn was prepared in the same manner as in Example 3. In the first coating, purified water was used with 4% sodium chloride (NaCl), and in the second coating, mineral oil and bentonite were prepared by adding 0.4% (w / w) of cotton wool, respectively. As a control, it was set as a coated cotton thread without primary coating after primary coating with purified water without sodium chloride (NaCl) added. Water activity was measured in units of hours from the time when the production of the second coated cotton yarn was completed. Water activity was measured using a water activity meter (available water analyzer, HP23-AW-A). The purified water added in the first coating process is free water, and it is mainly present in the outer surface of the coated cotton yarn at the point when the production of the coated cotton yarn is completed, but as time passes, it moves to the center of the seed chamber and evaporates or moves to the center of the coated cotton yarn. Moisture equilibrium is achieved. Free water, which is readily available to microorganisms, decreases storage properties and, when water activity is lowered, growth of microorganisms is inhibited. In the control group, the water activity decreased rapidly until 6-7 hours after production, but afterwards, it gradually decreased and finally stabilized at the level of 0.82, but after the first coating with 4% sodium chloride (NaCl) purified water, mineral oil ( When the secondary coating using mineral oil) and bentonite was completed, water activity decreased very quickly. This is because the mineral oil used for the secondary coating forms an oil film, and bentonite absorbs free water on the surface of the coated cotton thread. As a result, free water, which is easy to use for microorganisms, rapidly decreased, resulting in improvement in storage at the initial stage of production through this experimental example (FIG. 2).

Experimental Example 5. Measurement of aerobic stability

In the same manner as in Example 2, 100 kg of the primary coated coated cotton yarn was prepared in the same manner as in Example 3.

 In the first coating, 4% sodium chloride (NaCl) was used as the purified water, and in the second coating, mineral oil and bentonite were prepared by adding 0.4% (w / w) of cotton yarn weight, respectively. In the first coating, the moisture content of the coated cotton yarn was set to be 18%, which is to shorten the aerobic stability measurement period. For the measurement of aerobic stability, 2.5 kg of secondary coated cotton yarn was placed in a plastic container (20 l, circular container), and a sensor for temperature measurement was inserted in the center, and the temperature was measured at 1 hour intervals.

The temperature was measured using an aerobic stability meter (EG-1, UBI Korea) that automatically records the temperature of the sensor along with the environmental temperature. Aerobic stability was taken as the number of days when the difference between the environmental temperature and 2 degrees occurred. As a control, a coated cotton yarn coated with a secondary coating without adding sodium chloride (NaCl) to purified water during the first coating was used, and in general, propionate, which is commonly used for storage, was added at 0.3% for comparative evaluation. Table 4 shows the results.

Using 4% sodium chloride (NaCl) purified water, aerobic stability was measured (15.4 days) at a level similar to that of 0.3% treatment with propionate (13.7 days), which is generally used to improve storage, and 4% sodium chloride (NaCl) purified water It was confirmed that the aerobic stability was significantly improved to 46.2 days during the second coating using mineral oil and bentonite after the first coating using. As in Example 2, the moisture content of the coated cotton yarn was lowered to 14.5%, and it was confirmed that a coated cotton yarn having a very high storage capacity can be produced without drying during production (Table 4).

Experimental Example 6. 8mm screen pass rate measurement

In the same manner as in Example 2, 100 kg of the primary coated coated cotton yarn was prepared in the same manner as in Example 3. In the first coating, 4% sodium chloride (NaCl) was used as the purified water, and in the second coating, mineral oil and bentonite were prepared by adding 0.4% (w / w) of cotton yarn weight, respectively. As a control, it was set as a coated cotton thread without primary coating after primary coating with purified water without sodium chloride (NaCl) added. The passing rate was 8 mm in diameter, and 150 g of the coated cotton thread was placed on the perforated network (manufactured by itself) on the perforated network, and the pass rate meter was shaken to allow the coated cotton thread to pass through the 8 mm perforated network. When shaking the perforated network, each surface was shaken five times while rotating by 90 °. The pass rate was measured as the weight ratio of the coated cotton thread passed through as a 4 repetition average. The coating method and the material affect the surface of the coated cotton yarn, thereby changing the properties of the coated cotton yarn, and through these changes, a difference in the pass rate occurs. The higher the pass rate, the better the coating quality. The pass rate of the coated cotton yarn coated with the existing method was 81.2%, but the pass rate of the secondary coated cotton yarn with mineral oil and bentonite was 84.3%, confirming that the quality of the coated cotton yarn was improved through double coating (Table 5).

As shown in Table 1, the number of days in which the occurrence of microorganisms was confirmed in the sample group of the present invention in which the starch was not added in terms of the number of days of occurrence of microorganisms is on the average of 22 days, and the comparison group treated with starch was the average of microorganisms at 13 days. The occurrence was confirmed. In the control group, microbial development was concentrated in starch.

In terms of aerobic stability, the comparison group was 9 days, the sample group was 49 days, and the sample group without starch was 40 days longer than the comparison group. In particular, the difference from the day when the occurrence of microorganisms (fungi) was confirmed to the number of aerobic stability days was as short as 4 days in the comparative group, but the sample group was very long as 27 days. It was determined that the added starch promotes microbial development, which shortens the aerobic stability, leading to a decrease in shelf life (Table 6).
