BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger having an ultrasonic vibration function suitable for use when a liquid seasoning food or a semi-liquid food such as soy milk (hereinafter referred to as a semi-liquid) is efficiently heated and cooled in a short time. .

Conventionally, for example, when it is going to heat-process and cool foods, such as a liquid seasoning, in a short time and efficiently, a metal pipe may be heated, such as hot water, saturated water, or saturated steam, or cold water. The heat exchanger which pipes in the atmosphere filled with a refrigerant | coolant, and heat-exchanges between the liquid which flows in this metal pipe, and a fruit or a refrigerant | coolant was used widely.

However, when a liquid seasoning is heated and cooked or sterilized using a conventional heat exchanger, for example, heat-modifying components such as proteins in the liquid seasoning solidify and adhere to the inner wall of the metal pipe. It takes a long time to lower or wash deposits in the metal pipe. When the deposits of the deposits in the metal pipe are incomplete, these deposits become foreign matters such as pressed and gradually drop off and are mixed in the treatment liquid. Dissolved air which escaped from the liquid seasoning by the rise of liquid temperature adhered to the metal pipe for a while, and it extruded downstream in a wave shape, and there existed a problem of the nonuniformity in the flow volume in the metal pipe exit.

Therefore, as shown in Patent Literature 1, the present applicant, for example, in the case of heating or cooling various liquids such as liquid seasonings, various components in the liquid modified by heating or cooling, etc. We developed a heat exchanger and heat exchange method designed to prevent it from adhering to the inner wall of the furnace.

[Patent Document 1] Japanese Patent Application Laid-Open No. 2002-181490

According to the invention described in Patent Document 1, since ultrasonic waves generated by the vibration by the ultrasonic vibrator reach the metal pipe through the fruit or the coolant and vibrate it, for example, a liquid seasoning is passed through the metal pipe to be heated. In this case, the protein component and the like in the liquid seasoning modified by heating can be prevented from adhering to the inner wall surface of the metal pipe. The problem of mixing in the processing liquid can be solved, and the cleaning in the metal pipe can also be easily performed.

However, as shown in FIGS. 8 to 10, the heat exchanger described in Patent Document 1, by attaching a plurality of ultrasonic vibrators to the inside of the metal case body provided on the outer surface of the outer tank, each ultrasonic vibrator Since it is configured to radiate ultrasonic waves toward the metal pipes, the production cost is high, so that the whole of the heat exchanger is enlarged as much as these many ultrasonic vibrators are used. The heat exchange is large and limited to only liquids such as liquid seasonings. For example, semi-liquids such as soymilk have a problem such that heat exchange cannot be performed because the metal pipe is blocked.

Accordingly, the technical problem of the present invention is to prevent various components in the liquid modified by heating or cooling from being attached to the inner wall of the metal pipe by using only as few ultrasonic vibrators as possible, It is to provide a heat exchanger having an ultrasonic vibration function designed to be able to exchange heat smoothly and smoothly without heat clogging even a semi-liquid substance such as soy milk in a metal pipe.

(1) In order to solve the above technical problem, the invention according to claim 1 of the present application relates to a plurality of metal pipes through which a liquid such as seasoning or a semi-liquid such as soy milk flows, and the inside of a coat tank filled with a fruit or a refrigerant. A heat exchanger configured to perform heat exchange between a liquid or semi-liquid flowing in a metal pipe and a fruit or a refrigerant flowing in the metal pipe, wherein each metal pipe is spaced apart from the opening at both ends inside the opening at both ends of the coat tank. A liquid or semi-liquid body in which both end openings of the respective metal pipes communicate with each other inside the opening of both ends of the outer tank by providing a support plate for supporting both ends, and attaching a lid to each of the openings at both ends of the outer tank. Partitioning the chambers of the chamber, and at least one cover body of the coat tank, through the chamber An ultrasonic vibrator for radiating ultrasonic waves toward the distal opening of the metal pipe is attached.

(2) In the invention according to claim 2 of the present application, the right and left lids are detachably configured with respect to the openings at both ends of the coat tank, and one lid is provided with a plurality of ultrasonic vibrators. At the same time, the other cover body is characterized in that the inlet of the liquid or semi-liquid is provided with the outlet of the liquid or semi-liquid that has undergone heat exchange.

(3) The invention according to claim 3 of the present application is characterized in that a thin film such as Teflon (registered trademark) or ceramics is coated on the inner wall surface of the metal pipe to be piped in the coat tank.

According to said means mentioned in said (1), (2), (3), the ultrasonic wave generate | occur | produced by the vibration of an ultrasonic vibrator pulsates the liquid which flows in the chamber of a coat tank, and the vibration by this ultrasonic wave is a high chamber Since it can propagate inside each metal pipe having a tip opening open and vibrate effectively, a relatively small number (number) of coating a thin film such as Teflon or ceramics on the inner wall surface of each metal pipe. The ultrasonic vibrator can securely prevent adhesion of protein components and the like to the inner wall surface of the metal pipe, and can be reliably peeled off even when attached to the inside of the metal pipe to be removed (discharged) by the flow of liquid.

Further, according to the above means, the number of attachments of the ultrasonic vibrator can be reduced, so that noise during operation can be reduced, and even a semi-liquid such as soymilk can be easily heat exchanged by a powerful vibration action. Make it possible.
