Abstract

PURPOSE: To enlarge an evaporative area to a large extent and expand various kinds of functions by rotating a test tube at its central axis horizontally when concentration and drying of a material are carried out. CONSTITUTION: A test tube 1 is rotated around its central axis horizontally by a rotating shaft 4 through a rotor 3. An evaporative area is enlarged by this arrangement to increase the evaporation amount of a solvent. When the rotating shaft 4 is placed at the center of a tank by making use of the above arrangement, concentration and drying of large volume can be carried out. Also, as the position of the test tube 1 in the tank is fixed, various kinds of functions and forms can be developed. A thermometer can be inserted from above, and the temperature of a material itself can be measured. Or the material can be agitated to enlarge the surface area further. Or the material is injected continuously to carry out the concentration. Or, other materials can be added in the middle of operation. Also, a part of a data can be picked out tentatively during the rotation.

[0002] [Prior Art] A centrifugal evaporator rotates a test tube to suppress the bubbling and protrusion of the material solvent by centrifugal force, while discharging the air in the tank with a vacuum pump to concentrate and dry the material. It is something to do. Conventionally, as shown in FIG. 1, a test tube is rotated by mounting a rotor on a rotating shaft at the center of a tank and piercing the rotor at a certain angle (generally 15 ° to 50 °) with respect to the rotating shaft. The test tube was attached to the hole and rotated.

[0006] [Examples] Examples of the present invention will be described below. Experiments have shown that the magnitude of the liquid protrusion in a vacuum is proportional to the depth of the liquid in the container.
Add 15cc of water to a petri dish placed diagonally on the bottom of the tank,
When a vacuum of about 0.4 Toor is pulled, the protrusion occurs after about 1 minute, but most of it occurs in the deep water. Although it rarely occurs in shallow areas, it is not a large protrusion. Next, when the dish is made horizontal, the surface area is made large, and the water depth is made shallow, large protrusions do not occur at all. This tendency is more remarkable when 15 CC of water is divided into 3 petri dishes and placed horizontally. Therefore, if the water depth is made shallow, it is not necessary to use a large centrifugal force unlike the conventional centrifugal evaporator to suppress the protrusion. The ratio of the surface area of water during rotation in FIGS. 1 and 2 is determined by the inner diameter and length of the test tube, but in any case, FIG. 2 has a surface area several times that of FIG. Also, of course, the water depth will be shallow and the protruding force will be greatly diminished. Below, a comparison of the evaporation amount in a unit time when a normal centrifugal evaporator and a test tube are horizontally rotated about its central axis as shown in FIG. 2 is shown. A test tube with a normal rotor attached to a normal centrifugal evaporator. (Sakuma Seisakusho EC57-C) A test tube in the case where a normal rotor is attached to a centrifugal evaporator (Japanese Patent Application No. 3-198969) in which a far-infrared radiation object is applied to the inner wall of the tank by the present inventor.
