The present invention relates to a continuous far-infrared natural latex foam curing drying apparatus, and more particularly, a latex foam having a high moisture content is transferred to a plurality of drying chambers by directing a large amount of far-infrared radiation from top, bottom, left and right to be dried to transfer them quickly. The present invention relates to a continuous far-infrared natural latex foam curing drying apparatus capable of mass production and automation by drying latex foam in time.

Natural latex (latex) is produced by using a sticky liquid that oozes from the bark of Hevea brasiliensis, which is grown around the Malay Peninsula, and is commonly called natural rubber. In recent years, a well-being culture has emerged throughout the society, and among them, natural rubber is used for bed mattresses, pillows, and other cushioning materials such as sofas and cushions, which are used in homes. The products using natural latex (latex), which is impossible to format and can be used for a long time, are eye-catching.

However, since the cushioning material using the natural latex is molded by curing the liquid raw material, all of the moisture inside the cushioning material is not removed during the molding process. Therefore, since the best latex products can be produced only by removing all the moisture remaining in the molded latex, a drying apparatus for curing and drying the latex is required, and a latex drying apparatus has been conventionally disclosed.

The conventional latex foam drying apparatus is largely divided into a tunnel type and a fixed batch type. The tunnel type latex foam drying device transfers the transport truck carrying the latex foam into the hot air drying device made in the tunnel type and circulates strong hot air of about 80 ~ 120 ℃ for about 18 ~ 70 hours depending on the thickness of the latex foam. Cure drying.

However, such a tunnel type of the conventional hot air dryer apparatus has a problem in that the thermal efficiency is very low when drying and curing, and the temperature difference due to the air flow deviation inside the hot air dryer is large, so that the desired top quality is not obtained. In addition, the drying and curing time takes a lot, not only the production rate is lowered, but also the production cost is increased, and latex foam is exposed to high temperature for a long time, and product defects frequently occur due to surface damage and color change.

On the other hand, in order to improve the problems of the conventional tunnel type, as another conventional technology, a continuous RF (Radio Frequency) dry curing apparatus is disclosed. RF drying hardening device is a device to heat and dry latex foam by directly irradiating radio wave inside. The drying speed is very fast up to 95% of moisture remaining in latex foam, but it is impossible to remove remaining 5% of moisture. . In addition, the RF drying device does not have a cooling function, the internal temperature of the latex foam passed through the machine is very high, so long time cooling is required, and there is a problem that there is no hardening function to maintain the elasticity of the latex foam. Reheating requires secondary heating for about 3 to 10 hours. In addition, there is a problem that the control of the device is very difficult and requires a skilled driving technician.

Therefore, in order to improve the problems of the above-mentioned conventional hot air drying tunnel type and the fixed batch type latex drying hardening apparatus using RF, the latex drying apparatus currently disclosed is a plurality of drying chambers connected in a tunnel type, and transported inside the drying chamber. A transfer means installed along the direction to transfer the latex to the interior of the drying chamber, and near infrared radiation heat to the upper surface of the latex cushion material installed in the drying chamber and conveyed by the transfer means (latex cushion and circle It is composed of far-infrared heater which is irradiated and dried 30mm away from infrared radiation device. In addition, the lower surface of the latex cushion material passing through the drying chamber is also irradiated with far-infrared radiation heat (far infrared ray radiator surface temperature of 200 ° C. or lower) to maintain the same conditions as the upper surface, and then increases the water activity to increase the moisture inside the latex cushion material. After pushing out to the outside of the latex cushion material, the air supplied from the blowing fan carries moisture to be discharged to the outside through the exhaust fan to dry.

However, such latex dry hardening apparatus can produce latex foam of better quality than the conventional tunnel type or fixed batch type, but the latex foam which has passed through a plurality of drying chambers is dried quickly but the upper surface directly irradiated with heat source is rapidly The lower surface is difficult to dry completely. Therefore, the entirety of the latex foam is not evenly dried, so that the second heating is troublesome as in the conventional tunnel type described above, and there is a considerable difficulty in providing a good quality latex cushion material. In addition, since the heat source directly irradiated on the upper surface shows considerable high heat, it requires a double cost of having to separately reprocess the cooling device.

Therefore, the present invention has been created to solve the problems as described above, continuous far-infrared natural latex foam curing drying apparatus that can completely remove the moisture remaining in the latex cushion material in a short time to provide the best latex cushion material The purpose is to provide.

In addition, the present invention aims to provide a natural latex foam curing drying apparatus using radiation of far-infrared rays in a continuous process capable of continuously improving the productivity by performing curing drying and cooling of the latex cushion material in a short time continuously. .
