を動作させるためのモータ12も該装置１に設置される。Conventionally, when heating and sterilizing a fluid to be sterilized from a liquid to a high-viscosity paste, as shown in Japanese Utility Model Publication No. 63-5513 and FIG. 4, the material to be sterilized is passed through a pipe. A method of irradiating microwaves from outside has been used. The microwave heating sterilizer 1 according to this method is:
A hopper 2 for filling the material to be sterilized a, a pump 3 for pressurizing and sending the material to be sterilized from the hopper 2, a heating unit 4 for heating the material to be sterilized sent from the pump 3 by microwave irradiation, The pump 3 comprises a holding unit 5 for holding the temperature of the material to be sterilized, a cooling unit 6 for cooling the material to be sterilized through the holding unit 5, and a pressure control unit 7 for discharging a fixed amount. And a delivery path 8 made of, for example, a pipe material for delivering an object to be sterilized before passing through the pressure control unit 7. In the heating unit 4, there is a pipe 10, which is a part of the delivery path 8 and is provided from a microwave-permeable and heat-resistant material, in the microwave irradiation chamber 9. In order to stir, a rod-shaped stirrer 11 is arranged in the pipe 10. The stirring body 11
A motor 12 for operating the device is also installed in the device 1.

送出させることを目的とする。However, in the heating section of the above-described apparatus, the temperature of the object to be sterilized moving in the pipe under the microwave irradiation is gradually increased by irradiating the microwave with substantially uniformity, and the temperature of the object to be sterilized is reduced downstream under the irradiation. Since the temperature reaches a predetermined temperature (100 to 140 ° C) when the object reaches, a part of the material to be sterilized is easily carbonized and fixed on the inner surface on the downstream side of the pipe. In addition, there is a problem that the flow path is narrowed to make the delivery difficult. When the material to be sterilized is high in viscosity or when the delivery speed is low, insufficient stirring occurs, the temperature rise due to microwave irradiation becomes uneven, and there is a problem that uneven heating and insufficient sterilization occur. . Therefore, the carbonization in the pipe downstream portion of the heating unit is eliminated, and even when the material to be sterilized has a high viscosity or when the delivery speed is low, uneven heating and insufficient sterilization are to be prevented. It is an object of the present invention to raise the temperature of an object to be sterilized to a predetermined temperature by microwave irradiation and to appropriately send out the object from a heating unit.

である。The present invention has been made in consideration of the above problems,
A microwave-permeable pipe made of a heat-resistant material is passed through a fluid or a high-viscosity paste-like material to be sterilized, and while being irradiated with microwaves from the outside of the pipe, stirring is provided inside the pipe. In a microwave heating sterilization apparatus for stirring an object to be sterilized by a body, the stirring body has a rotating wing portion that is positioned at a downstream portion of the pipe under microwave irradiation and that rotates while sliding on the inner surface of the pipe. An object of the present invention is to provide a wave heating sterilizer to solve the above-mentioned problem.

うになり被殺菌物の移動がスムーズになる。In the present invention, the rotation of the stirrer stirs the pipe from the upstream side to the downstream side, and the rotation of the rotating blades on the downstream side further causes the entire sterilized substance in the downstream side pipe to adhere to the pipe. As a result, the material to be sterilized is smoothly moved.

Parts having the same configuration as the conventional example shown in FIG. 4 are denoted by the same reference numerals, and description thereof will be omitted. As shown in FIG. 1, a stirrer 11 of the microwave heating and sterilizing apparatus 1 includes a rotating rod 13 extending from an upstream side to a downstream side in a pipe 10 in a heating unit 4, and a rotating member located downstream of the pipe 10. Wing portion 14, and the rotating wing portion 14 includes a rotating rod portion 13
A pair of wing pieces 14b is attached to the rotation center 14a screwed to the tip screw 13a of the
The upper edge of each of the wing pieces 14b slides on the inner surface of the pipe 10 and rotates together with the rotary rod portion 13. The screwing of the tip screw 13a and the rotation center 14a is performed in a direction in which the tip is closed by the rotation of the rotating rod 13. The wing piece 14
Each of the b is inclined toward the direction of the rotation axis on the upstream side in order to reduce the resistance to the body to be sterilized passing through the pipe 10, and is thinly provided toward the upper edge in contact with the inner surface of the pipe. By rotating the stirring body 11 composed of the rotating rod portion 13 and the rotary wing portion 14, the material to be sterilized is stirred in a portion extending from the upstream to the downstream of the pipe, and the temperature of the material to be sterilized reaches a predetermined temperature. Even on the downstream side where the temperature rises, the object to be sterilized moves so as to be largely scraped off by the rotary wing portion 14 and is sent out without being carbonized and fixed. Each of the rotating rod portion 13 and the rotating blade portion 14 is made of a material having a small dielectric loss, and is formed of, for example, Teflon or ceramic. The amount of the object to be sterilized by the pump, the number of revolutions of the stirrer, and the pipe diameter are appropriately set for the object to be transmitted.
