Description

Wet rice flour manufacturing method using rice flour manufacturing appratus

The present invention relates to a rice flour manufacturing method using a rice flour manufacturing apparatus, and more particularly, to a wet rice flour manufacturing method using a rice flour manufacturing apparatus capable of packaging rice flour having a moisture content of 30 to 35% in a separated state without agglomeration.

Dry milling and wet milling are known as methods of milling (grinding) spicy rice.

Dry milling method is economical because it is simple and inexpensive, but has the disadvantage of poor quality. Conversely, wet milling method has excellent quality but high drying cost and causes water pollution. Therefore, dry milling method is preferred for commercial rice flour. there is.

However, in the case of the rice cake manufacturing industry, which uses a lot of rice flour, the quality of rice cakes made from dry milled rice flour is not good, so rice flour is made by wet milling to manufacture rice cakes.

Currently, the production of rice cakes for rice cake soup, which accounts for the largest portion of rice processing products in Korea, is wet-milled after immersion, so a large amount of wastewater is discharged. On the other hand, it is difficult to commercialize because it is more than 35% and it cannot be distributed at room temperature. On the other hand, when dry rice flour is manufactured, starch damage is severe and it is difficult to form rice cakes.

Although wet rice flour has the above problems, it has less starch damage than dry rice flour, so it has a relatively rich rice flavor, and has the advantage of excellent taste and flavor when rice cakes are made with this material. In this case, preference for wet rice flour is higher than dry rice flour.

However, in the production of wet rice flour, when the moisture content in the rice flour increases, the rice flour is agglomerated by the surface tension of the water to form a lump, so there is a difficulty in the sieving operation.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1, the wet rice flour manufacturing method using the rice flour manufacturing apparatus according to the present invention is a washing step (S100), a soaking step (S200), a dehydrating step (S300), a grinding step (S400), an annealing step (S500), It may include a sieving step (S600), a pouch packaging step (S700), a metal detecting step (S800), and an outer packaging step (S900).

The first step, washing step (S100), is a process of putting an appropriate amount of spicy rice into a washing machine (not shown) of the rice flour manufacturing apparatus and washing. , It is a process of rotating the washing container and flowing the washing water inside it so that the spicy rice is washed by the flowing washing water. Here, for effective washing, it is preferable that a plurality of protrusions for causing irregular flow of washing water are formed on the inner circumferential surface of the washing tank.

In other words, the washing tub is provided in a state rotatable in the forward or reverse direction by a motor, and to one side of the outer circumferential surface of the washing bin, spicy rice and washing water are put in, or washed rice is recovered, or contaminated water is discharged after washing. An entrance may be provided for. The doorway is hinged on the washing tub, and the other side may be opened or closed by a door that can be opened and closed by a clamp (not shown).

Here, the rice washing step is preferably washed with water twice or more for 3 minutes or more each. In general, since the amount of rice added to the washing bin is 300 kg or less, it has an appropriate bulky feeling even if it is not a large amount. Therefore, it is appropriate to wash the rice for 3 to 5 minutes in order to wash the rice evenly experimentally, and if it is washed only once, foreign substances are washed It may not be discharged from the barrel, so it is preferable to wash it 2-3 times.

The second step, the soaking step (S200), is a process of immersing the washed rice in a soaking container containing water. This soaking process is a softening process for increasing the grinding efficiency during the grinding process as well as increasing the water content by infiltrating the rice with moisture.

Patent Registration No. 10-1894370, which is a prior patent, emphasizes the advantage that there is no wastewater generation and quicker time to absorb moisture compared to the immersion method by adopting the spray method during soaking. It would be common sense to say that water absorption is faster and more effective than the spray method.

Here, the immersion time is preferably 2 hours or more. In the case of immersion for less than 2 hours, the desired water content cannot be obtained, and in the case of more than 3 hours, overwatering occurs, so 2-3 hours is appropriate.

The third step, the dehydration step (S300), is a process of natural dehydration by putting the soaked rice in a porous dehydration container capable of gravity dehydration. In the case of centrifugal dehydration, in which soaked rice is put in a centrifugal dehydrator and dehydrated by forcibly rotating, starch is damaged, and natural dehydration is preferably applied despite the relatively long dehydration time.

Here, as for the natural dehydration time, the dehydration time should be allocated until the moisture content becomes 30 to 35% according to the data obtained through repeated experiments.

The fourth step, the grinding step (S400), is a process of milling by putting dehydrated rice into the hopper of the rice flour manufacturing apparatus, and allowing the rice discharged through the lower outlet of the hopper to be inserted between a pair of grinding rollers.

The roller grinding is a state in which the rice retains moisture as much as possible by natural dehydration, so it is possible to suppress the generation of frictional heat during grinding and to grind easily without destroying nutrients. In addition, heat generation can be obtained by water cooling the grinding heat by moisture during roller grinding, and rice flour can be prevented from adhering to the surface of the roller, so that good quality rice flour can be obtained.

The unwinding step (S500), which is the fifth step, is a very important process in the present invention, and the pulverized wet rice flour is put into the stirrer of the rice flour manufacturing apparatus, and the stirring blades of the stirrer are rotated to loosen the wet rice flour so as not to agglomerate. Without this annealing step, a phenomenon of agglomeration of rice flour with high moisture content occurs, which prevents smooth sieving in the sieve step, which is a post-process, and significantly reduces the efficiency of collecting rice flour.

The 6th step, the sieving step (S600), is a process in which the separated wet rice flour is put into a vibrating sieve device and sieved, but only particles having a particle size of 20 mesh or less are collected. This step is to obtain and use rice flour of a homogeneous particle size through sieving of the wet rice flour. can

The seventh step, the pouch packaging step (S700), is a process of measuring the moisture content of the sieved wet rice flour, and packaging the pouch only when the moisture content is 30 to 35%.

Here, as a result of measuring the moisture content of the wet rice flour by a moisture meter, if the moisture content of the wet rice flour is less than 30%, the wet rice flour is sprayed with water and then put back into the stirrer. input and repeat the previous process.

When the pouch packaging is completed, a process of freezing the wet rice flour for more than 4 hours in a freezer at -18°C may be additionally performed to prevent moisture evaporation and to prevent deterioration. Accordingly, preservatives are possible, and the shelf life can be extended.

The eighth step, metal detection step (S800), is a process of detecting iron powder of Φ2.0mm or more and stainless powder of Φ2.5mm or more contained in the rice flour by passing the pouch-packed wet rice flour through a metal detector. That is, in this step, the presence of iron powder and stainless steel over the set size contained in the rice flour harmful to the human body is detected. As a result, if metal powder over the set size is detected, the wet rice flour is discarded.

Finally, step 9 (S900) is an outer packaging step, and the wet rice flour satisfying the conditions is sealed and packaged and shipped to the market or stored.

On the other hand, the anti-contamination film may be attached to the inner peripheral surface of the hopper by an adhesive. The adhesive composition according to an embodiment of the present invention comprises 40 to 80 parts by weight of a thermoplastic resin, 5 to 40 parts by weight of a tackifying resin, 1 to 5 parts by weight of rosin, 1 to 10 parts by weight of a plasticizer, 1 to 10 parts by weight of a filler and It may contain 0.1 to 1 part by weight of antioxidant.

The thermoplastic resin, as a main component of the composition, functions to control adhesion and cohesion. If it contains a vinyl group or a hydroxyl group, the type is not significantly limited, for example, ethylene vinyl acetate copolymer, polyvinyl acetate, polyvinyl alcohol, ethylene-acrylic acid copolymer and ethylene-methacrylic acid copolymer, polyurethane. It may be composed of any one or more selected from the group consisting of.

The content of the thermoplastic resin is preferably 40 to 80 parts by weight based on the total composition. When the content is less than 40 parts by weight, the melt viscosity is high and the melt flow index is low, so that workability is very poor. When the content is more than 80 parts by weight, it is difficult to exhibit sufficient adhesion.

The tackifying resin is a low-molecular-weight resin, which improves workability by lowering melt viscosity, improves initial wettability of adhesion and adhesion on the surface of the adherend of the adhesive, and enables control of solidification time, etc.

The type of the tackifying resin is not particularly limited, but it is preferably a petroleum resin. More specifically, the tackifying resin may be composed of at least one selected from the group consisting of an aliphatic hydrocarbon resin, an alicyclic hydrocarbon resin, an aromatic hydrocarbon resin, an aromatic-modified aliphatic hydrocarbon resin, and a hydrogenated hydrocarbon resin.

The aliphatic hydrocarbon resin is a commercial product, and there are Hikorez A-1100, Hikorez A-1100S, Hikorez C-1100, Hikorez R-1100, Hikorez R-1100S and the like of Kolon Chemical. In addition, the alicyclic hydrocarbon resin includes a hydrocarbon resin containing dicyclopentadiene (DCPD) as a monomer, and the aromatic hydrocarbon resin is commercially available from Kolon Chemical's Hikotack P-110S, Hikotack P-120, Hikotack P-120HS, Hikotack P-120S, Hikotack P-140, Hikotack P-140M, Hikotack P-150, Hikotack P-160, Hikotack P-90, Hikotack P-90S, Hirenol PL-1000, and Hirenol PL-400. In addition, commercially available aliphatic hydrocarbon resins modified by aromatics include Hikorez T-1080, Hikorez T-1100, and the like of Kolon Chemical. In addition, the hydrogenated hydrocarbon resin may be subdivided into a hydrogenated aliphatic hydrocarbon resin, a hydrogenated aromatic hydrocarbon resin, etc., and commercially available from Kolon Chemical Co.'s Sukorez D-300, Sukorez D-390, Sukorez SU-100, Sukorez SU-110, Sukorez SU-120, Sukorez SU-130 and Sukorez SU-90.

The tackifying resin is preferably a hydrocarbon resin having 4 to 10 carbon atoms in the monomer, and specifically, C5 aliphatic resin, C9 aromatic resin, C5/C9 aliphatic/aromatic copolymer resin, etc. may be used.

In addition, the tackifying resin according to the present invention is more preferably characterized in that it is a hydrogenated hydrocarbon resin containing dicyclopentadiene as a monomer. Sukorez SU-100, Sukorez SU-110, Sukorez SU-120, Sukorez SU-130 and Sukorez SU-90.

On the other hand, the adhesive composition according to the present invention is preferably used by mixing the biodegradable hypoallergenic resin with the various petroleum resins described above.

The biodegradable hypoallergenic resin may be prepared by melt-mixing a polymer monomer with a biodegradable polymer, and polylactic acid is preferably used as the biodegradable polymer.

The polylactic acid is a polyester synthesized by polycondensation of lactic acid or ring-opening polymerization of lactide, and has properties intermediate between polyamide and polyethylene terephthalate. It has high biodegradability, but generally has high hardness, low elasticity, and low durability.

The biodegradable polymer is melt-mixed with the same polymer monomer. At this time, the biodegradable polymer is combined with the monomer and chain cleavage is partially generated, thereby reducing the overall number average molecular weight. As the number average molecular weight decreases, physical properties that can be used as a pressure-sensitive adhesive are exhibited, and processability is increased.

Based on 100 parts by weight of the polylactic acid, 20 to 30 parts by weight of the lactic acid monomer may be mixed. When the monomer is mixed in less than 20 parts by weight, the number average molecular weight is high and hard, so it is difficult to use as an adhesive, and when the monomer exceeds 40 parts by weight, migration occurs on the surface and it may also be difficult to use as an adhesive.

The mixing ratio of the petroleum resin and the biodegradable hypoallergenic resin is preferably 1-2:1 (w/w), and when the mixing ratio of the petroleum resin is too high, it is difficult to obtain the biodegradable hypoallergenic effect, and the If the mixing ratio is too high, economic feasibility may be deteriorated and the overall adhesion effect may be reduced.

In addition, the content of the tackifying resin is preferably 5 to 40 parts by weight based on the total composition. If the content is less than 5 parts by weight, the effect of lowering the melt viscosity due to the addition of the tackifying resin is insignificant, and there is a concern that the workability may not reach a satisfactory level because the increase in the melt flow index is not large accordingly, and the content exceeds 30 parts by weight If the melt flow index increase rate due to the excess of the tackifying resin is not large, economical efficiency is deteriorated and the content of the thermoplastic polymer is relatively reduced, which may reduce the overall physical properties of the composition.

The rosin serves to improve the overall adhesion of the adhesive composition, is harmless to the human body, and serves as a natural preservative. The content of the rosin is preferably 1 to 5 parts by weight based on the total composition. If the content is less than 1 part by weight, it is difficult to obtain an effect of improving adhesion, and if the content exceeds 5 parts by weight, the adhesive strength increases during processing, thereby making processing into a product difficult.

The plasticizer is used to impart flexibility and adhesiveness to the polymer, and the type of the plasticizer according to the present invention is not particularly limited, and includes, for example, sorbitol, ethylene glycol, glycerin, glycerin diacetate, and pentaerythritol. It may be composed of one or more selected from the group consisting of.

The content of the plasticizer is preferably 1 to 10 parts by weight based on the total composition. If the content is less than 1 part by weight, the effect of the addition of the plasticizer is insignificant, and if the content exceeds 10 parts by weight, economic feasibility may be deteriorated due to excessive use of the plasticizer, and there is a risk of lowering the overall physical properties of the adhesive.

The fillers are used to control the reinforcing and flow properties of the composition. The type of filler is not particularly limited, and for example, calcium carbonate, clay, bentonite, or calcium stearate may be used.

If the content is less than 0.1 part by weight, the effect of the addition of the antioxidant is insignificant, and if the content exceeds 1 part by weight, the economic feasibility of the adhesive is deteriorated and there is a risk of lowering the overall physical properties.

On the other hand, the adhesive composition according to the present invention is subjected to a press operation on the antifouling film.

Accordingly, the adhesive composition according to the present invention may further include a nano-silica number capable of improving adhesion by uniformly distributing the adhesive composition on the film surface. At this time, the content of the nano-silica is preferably 0.1 to 5 parts by weight, and the size of the nano-silica (primary particles) is preferably 100 nm or less.

When the content of the nano-silica is less than 0.1 parts by weight, the effect of adding nano-silica is insignificant, and when it exceeds 5 parts by weight, the adhesive strength is lowered, and as time goes by, blooming occurs on the surface of the adhesive. can occur
