Description

Agri-food drying plate {A drying mat}

The present invention relates to an agricultural and aquatic product dry plate using a planar heating element, and more particularly, to a dry agricultural product that can be re-contacted even if any one of the carbon fibers in the surface heating element consisting of a plurality of carbon fibers.

In general, agricultural products such as red peppers, rice barley or agricultural products, especially anchovies or rice, which are harvested from the mountain region, must first be dried for storage and transportation until reaching the consumer. This is because agricultural products such as anchovies and rice harvested from mountain areas are usually high in water content, so they are easily deteriorated or decayed, resulting in quality deterioration and quantitative loss of grain. Therefore, agricultural products such as rice should be dried to have a moisture content of about 15% for safe storage, harvesting and preservation of food immediately after harvesting.

To this end, in rural areas, agricultural products are dried with sunlight while a certain unevenness is laid out on the road, and recently, a large grain dryer is used.

However, the method of using the dolmen of the above-described method is not only take a long time to dry because drying only depending on the sunlight, the drying object is not evenly dried, grain dryers can be safely stored and fast drying, but There was a problem that it costs a lot to buy.

In order to solve this problem, the Republic of Korea Utility Model Registration No. 334054 (Agricultural aquatic products dry bark) has been disclosed that the applicant has applied for a utility model registration application. Briefly described with reference to Figure 1 of the agricultural and marine products dry dense, having a dimple shape is formed on the drying layer 10 and the bottom of the drying layer 10 of the network structure and the heat generated by the electrode 22 The heat generating layer 20 and the heat insulating layer 30 disposed below the heat generating layer 20 to insulate. At this time, the carbon fiber 24 of several strands is disposed between the two electrodes 22 to generate heat evenly spread to the dry layer 10. In addition, the thermal insulation layer 30 is a flame-retardant thermal insulation material 32 and a functional protective material in order to prevent the heat of the heat generating layer 20 is transmitted to the ground and at the same time to prevent cold air from being transferred to the heat generating layer 20. 34 is made in an overlapped form.

However, the above-described conventional agricultural and dry products (1) has a problem that the carbon fiber is often short-circuited at the center of the carbon fiber or the interface between the carbon fiber and the electrode.

The present invention is devised to solve the above problems, an object of the present invention is to provide a plurality of carbon fibers in parallel to the electrode having a power supply to both ends of each carbon fiber and to the central portion of each carbon fiber By providing an auxiliary electrode to connect, not only can be generated in each carbon fiber individually, but also relates to the agricultural and aquatic product drying plate that can be re-contacted by the auxiliary electrode even if any one of the carbon fibers short.

Still another object of the present invention is to provide a dry agricultural and aquatic product plate that can prevent the carbon fiber from short-circuit by applying heat-resistant silicone to the interface between the electrode and the carbon fiber.
