Dry molding machine for manufacturing in-line type continuous coating oral disintegrating film

The present invention relates to a dry molding machine for manufacturing an in-line continuous-coated oral dispersible film, and more particularly, a liquid raw material is used as a coating machine when manufacturing an oral disintegrating film used for film-type food, health supplements or pharmaceuticals. It relates to a dry molding machine for manufacturing an in-line continuous body coating orally disintegrating film improved to improve drying quality by being able to sufficiently dry without spatial restrictions by using an extended drying furnace while continuously coating it.

In general, orally disintegrating film is made in the form of a thin film by mixing a material beneficial to the human body with a raw material that is not harmful to the human body and dissolves well in water, such as starch, and is usually called an edible film.

Therefore, by putting such an orally disintegrating film in the mouth and dissolving it with saliva, it is possible to easily administer substances beneficial to the human body into the body.

In addition, in some cases, it is possible to administer cosmetics or drugs by attaching an orally disintegrating film to the skin or the like.

Recently, it is also used as an oral freshener containing a substance for removing and preventing bad breath and a freshening fragrance and color such as mint or menthol in an oral disintegrating film.

However, since the orally disintegrating film is weak against moisture and provided in the form of a thin film, it is cut to an appropriate size and sealed with wrapping paper, or orally disintegrating film cut to a certain size is stored in a dispenser and pulled out one by one. It is used in the form of

Among them, in the case of packaging the orally disintegrating film as a sheet, the production efficiency is lowered because the oral disintegrating film production line and the packaging line are installed separately in the prior art, and there were many inconveniences due to the arrangement of the equipment and the provision of the equipment.

1 is a part of the improved [prior art document], a liquid supply unit 110 for supplying a liquid raw material, a coating conveyor 130 that is a coating transfer support plate of a liquid raw material, and the upper surface of the coating conveyor 130 The lower wrapping paper supply unit 140 for packaging the film and the liquid raw material supplied from the liquid supply unit 110 are coated on the upper surface of the lower wrapping paper 141, but the film 101 separated individually by multiple intermittent coating Multiple for coating The intermittent coating machine 120 and the dryer 150 installed at the rear including a part of the coating conveyor 130 to dry the film 101 coated by the multi-intermittent coating machine 120, and the dryer 150 pass The upper wrapping paper supply unit 160 for supplying the upper wrapping paper 161 to the upper part of one film 101, and the upper wrapping paper 161 and the lower wrapping paper 141 around the circumference of each film 101 are bonded to each other by thermocompression bonding. The heat sealer 170 for sealing the film into individual packaging, the slitter 180 for separating the products sealed for each film by the heat sealer 170, and the product separated by the slitter 180 It consists of a cutter 190 that cuts into individual packaging, and the orally disintegrating film production line and the packaging line have been inlined.

However, in the case of FIG. 1, since the space in which the dryer 150 can be installed is limited, it is very difficult and difficult to design a drying furnace that can sufficiently perform the drying molding function within the limited space, and in the end, the length of the equipment has to be lengthened. is at the limit. For this reason, if the length for installing the equipment is not sufficient, eventually fall into a contradiction that leads to a problem in principle in which the oral disintegration film production line and the packaging line must be separated again as in the prior art.

Hereinafter, a preferred embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

The dry molding machine for in-line production of an orally disintegrating film according to the present invention is a means for drying and curing the chemical layer (MDL) coated on the base film (BA), which is a substrate, as illustrated in FIGS. 2 and 3 .

In the present invention, the structure of such a drying molding machine is specially designed, but one having a plurality of drying zones can be exemplified.

The drying machine 300 includes a plurality of drying zones, as illustrated in FIGS. 4 to 6 .

Preferably, the drying zone may be composed of first, second, third, fourth, and fifth drying zones (Z1, Z2, Z3, Z4, and Z5).

Of course, it goes without saying that the number of drying zones can be designed differently depending on the treatment target. However, in the present invention, it is characterized in that it is designed to maximize the holding time of the base film (BA) while maintaining the size of the existing drying furnace of the orally disintegrating film.

That is, although it is a dryer of the same size as the existing one, if implemented according to the present invention, the length of the base film (BA) can be significantly increased from the existing 15m to 21m, and thus a high-quality dried product can be made.

In particular, since the effect of processing with a larger facility is obtained without designing the facility larger, the cost is reduced and the treatment efficiency is increased.

In addition, in the present invention, a drying zone having at least one or more triple drying means is included among the drying zones, and the rest has a structure having a double drying means. And, it goes without saying that the arrangement of these drying zones can be variously arranged and used according to the treatment object or treatment environment.

In this case, the heat source used as a drying means is configured to increase drying efficiency by diversifying into IR (infrared), hot air, and heater, and a rolling type in which at least several zones are folded in order to efficiently dry a short length in a drying tunnel. By implementing the structure, it is possible to optimize the drying conditions.

In particular, unlike the existing (temperature deviation occurrence) in which each drying zone was blocked, all five drying zones are connected and open and not clogged. It is configured to be easy to do.

For example, as shown, the first drying zone Z1 is provided with a triple drying means so that it can be dried quickly by providing all three types of heat sources: heating, hot air, and infrared irradiation.

In addition, a preheater 310 having a preheating function is installed at the start end of the first drying zone Z1, but is omitted from the enlarged view of FIG. 5 .

The preheater 310 is for preheating the conveyed base film BA to rapidly increase drying efficiency when the main drying starts.

That is, since the first drying zone Z1 is at the time when the base film BA is input, the chemical solution layer MDL is in a state in which it is not yet dried.

Therefore, in the first drying zone Z1, it is necessary to harden the chemical solution layer MDL to have a certain viscosity or less as quickly as possible while horizontally moving the base film BA.

To this end, in the present invention, a preheater 310 is included in the first drying zone Z1, and while supporting the base film BA so as not to sag while being conveyed, from the lower part of the base film BA to the upper part, That is, it includes a hot plate 3100 for supplying heat so that drying is made quickly from the inside of the chemical solution to the outside.

The hot plate 3100 is a kind of heater as a heating plate. Therefore, direct heat is applied while in contact with the lower surface of the transferred base film BA to dry and harden the chemical solution layer MDL coated on the surface.

In addition, a hot air supply duct 3200 is installed at an upper portion of the base film BA at an interval.

In addition, a plurality of hot air nozzles 3210 are provided on the lower surface of the hot air supply duct 3200 at intervals, and an infrared irradiator 3300 is further installed in the space between the hot air jets 3210 .

The infrared irradiator 3300 is a means for penetrating to the bottom of the chemical layer (MDL) and hardening it from the inside. In the case of a viscous material such as collagen, only the outside is hardened and the inside is not hardened by simply hot air or heating. It is used to harden both the inside and the outside at the same time because defects occur while the shape is deformed.

In addition, a heater 3400 is installed at an upper portion of the hot air supply duct 3200 , and a blowing fan 3500 is installed at the uppermost end thereof.

Thus, when the blower fan 3500 blows air, the air is heated by the heater 3400, rides the hot air supply duct 3200, and is sprayed directly above the base film BA through the hot air jet port 3210. The chemical liquid layer (MDL) is dried and cured.

In this case, the controller 3600 is installed in the hot air supply duct 3200 to automatically adjust the pressure and the blowing speed. For this purpose, the controller 3600 includes a pressure gauge and a speed gauge.

In particular, a pre-filter, a medium filter, and a Hye-pa filter are built-in in the exhaust part of the facility where the blowing fan 3500 is installed, so that it is better to configure it to maintain a cleanliness of 100,000 classes. This can keep the tunnel inside the cleanroom concept.

Here, the drying efficiency can be maintained in an optimal state by managing the hot air at 250-350°C, the heating by the heating plate at 350-450°C, and the infrared heating at 450-550°C. That is, it is particularly preferable to control the temperature distribution of these heat sources so that the temperature of each drying zone is maintained at 80-110°C.

On the other hand, in the second, third, and fourth drying zones (Z2, Z3, Z4), the upper guide roll 3700 and the lower guide roll 3800 are installed at intervals up and down to extend the flight time, but are transferred through The base film (BA) is arranged and designed to be transported in a constant rolling type, that is, in a wave shape that alternately repeats troughs and ridges.

Therefore, it has a longer flight time by that much.

At this time, the upper guide roll 3700 is installed on the lower surface of the hot air supply duct 3200, and the lower guide roll 3800 is installed on the bottom surface of the drying zone.

Here, it should be noted that in the case of the second, third, and fourth drying zones Z2, Z3, and Z4, there is no heating plate, and only hot air and infrared rays are used to dry and harden the zone.

Therefore, when the infrared irradiator 3300 irradiates, the positions of the upper guide roll 3700 and the lower guide roll 3800 are well selected and arranged so that the base film BA can be irradiated only when the bone state is always maintained. .

In addition, an edge position controller (EPC) sensor is installed in the second, third, and fourth drying zones (Z2, Z3, Z4) or at a point where there is a risk of meandering to prevent meandering when the base film BA proceeds. .

In this case, the EPC sensor can be installed inside or outside the drying zone, for example, as in the example of FIG. 2 , the external EPC sensor 3900a and the internal EPC sensor 3900b are them, and the reason why the EPC sensor is needed 7, the upper guide roll 3700 and the lower guide roll 3800 have a special structure consisting of a base contact portion (BTC) and a groove portion (YO), which is a chemical layer coated on the base film (BA). If (MDL) is not completely dried yet, if a wave is drawn up and down while moving along these guide rolls, the chemical solution layer (MDL) falls off at the bent part while in contact with the guide roll, and this is to prevent this. .

That is, the portion in contact with the guide rolls is the base contact portion (BTC) and only the base film (BA) is in contact, and the chemical layer (MDL) is not affected by folding or bending by the guide rolls because it is located in the groove portion (YO). Smooth zigzag transfer is possible.

When the drying furnace 300 is configured in this way, a complete drying effect can be obtained according to the extension of the air time, the drying efficiency is improved compared to the same size, and both the inside and the outside of the chemical liquid layer (MDL) are uniformly cured together, so the As a result, the quality of the product can be improved.

In addition, the fifth drying zone Z5 may be configured in the same manner as the first drying zone Z1 without a preheater. Of course, this is only one preferred embodiment, and each zone may be mixed and arranged in various forms. In the present invention, only the case where there are three heat sources and the case where the heat sources are two have been exemplarily described.

In addition, as shown in the example of FIG. 2 , a visual test unit TST is further formed on the external EPC sensor 3900a at the point passing through the drying molding machine 300 . The visual test unit (TST) is made of a transparent window and allows to directly check whether the chemical is cracked with the naked eye. This can reduce the defect rate by checking whether the applied and dried high-temperature chemical layer is bent along the radius of the roller after it is cooled by the external atmospheric air, and then measures whether cracks occur.
