Description

[Detailed description of the invention]

(A) Industrial Application Field The present invention relates to an improvement in a method for producing dried plants with good storage stability by drying plants such as flowers quickly and beautifully in large quantities. (B) Conventional technology The conventional method of making dried plant bodies, so-called pressed flowers, is to sandwich the plant body between paper or cloth and press it.Additionally, a dehydrating agent such as silica gel is added under the paper or cloth. A method was also used to place In addition, in order to speed up the dehydration rate, calcium chloride or lithium chloride, which has a stronger dehydrating power than silica gel, is added to paper or cloth, and the paper or cloth is placed in direct contact with the plant by sandwiching it between urethane pine mats, and then heated. Methods have been devised to completely dehydrate plants at an early stage. (C) Problems to be solved by the invention Conventional methods using only paper or cloth or using silica gel have relatively weak dehydration power and have a structure in which the distance between the plant body and the silica gel is large. It took a long time for the body to dehydrate, which resulted in incomplete dehydration, and the resulting dried plant body often changed and discolored in a relatively short period of time. In addition, the method of heating a plant body by placing calcium chloride or potassium chloride in paper or cloth and sandwiching the paper or cloth with a urethane mat is because calcium chloride and lithium chloride have the property of deliquescing and becoming liquid as they absorb heat. , moisture spreads throughout the paper or cloth containing this, and when heated, the humidity continues to rise over time, causing a stuffy state, and thus it takes a relatively long time for the plant body to dehydrate and dry. The disadvantages were that the plants were easily discolored, shriveled, and deformed. Furthermore, since urethane pine has insulating properties, when stacked with paper or urethane pine in multiple tiers and pressed together, heat does not conduct on average, so it is difficult to stack them in multiple tiers to produce a large amount of dried plants at once. There were drawbacks such as the inability to (D) Means for Solving the Problems The present invention was invented to solve the problem, and the present invention can be explained with reference to the drawings. The material is sandwiched between thick conductive paper or cloth 5, stacked in multiple tiers, and then sandwiched between electric heating mats 2, which are further sandwiched between press plates 1, and heated and pressed for several hours. (E) Effect The present method is as described above, and since anhydrous magnesium sulfate has the property that it does not deliquesce even if heat absorption progresses, but only increases in volume, the drying sheet will absorb water throughout the drying sheet due to the deliquescent action. By heating it over time, the humidity will increase and stuffiness will not occur. In addition, as the means for holding the plants together with the drying sheets, we do not use urethane mats, but use thick paper or cloth with heat-conducting cushioning properties, so the heat generated by the electric heating mats can be used to hold a large amount of drying sheets and It is transmitted on average to cushion sheets, etc. (F) Effect Due to the above-mentioned effect of preventing the drying sheet and the cushioning sheet in contact with it from becoming stuffy, discoloration and creasing of the shape caused by dampness occur in a relatively short period of time and qualitatively. In addition, dried plants with beautiful colors and good shapes and a relatively good shelf life can be obtained. Further, by the action of transmitting heat on average to the multi-tiered drying sheet and the cushioning sheet in contact with the drying sheet, a large amount of uniform dried plant matter can be obtained in a short time.
