DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a heat exchange treatment apparatus for a liquid or the like, by passing the liquid or the like through a helically formed helical tube portion accommodated in a tank in which water is stored. The present invention relates to an improvement in a heat exchange processing device used to cool a liquid or the like transferred in a helical tube to a desired temperature or to heat it to a desired temperature.

[0002]

2. Description of the Related Art Spirals containing liquids such as noodle soups, ramen soups, dressings, sauces, and various kinds of sauces and other heat-exchange processing fluids such as foods and seasonings are stored in a tank in which water is stored. While passing through the spiral tube portion formed in a shape, by adjusting the temperature of the water stored in the tank, the heat exchange treatment fluid transferred in the spiral tube portion is cooled to a desired temperature, or,
There is a heat exchange processing apparatus that can heat the heat exchange processing fluid to a desired temperature.

[0003] In this heat exchange treatment apparatus, it is necessary to periodically clean the inside of the helical tube from the viewpoint of hygiene. When the type of the heat exchange processing fluid is changed, the inside of the helical tube portion is washed so that the heat exchange processing fluid that has been processed earlier and the heat exchange processing fluid that is to be subsequently processed are not mixed. It needed to be done.

[0004]

However, in the conventional heat exchange processing apparatus, the spiral pipe section through which the heat exchange processing fluid passes is fixed to the tank in a non-removable state, so that only the spiral pipe section is used. It was not possible to carry out immersion washing or the like, and it was difficult to easily ensure the hygiene of the food or the like when heat-treating the food or the like.

Further, in the maintenance and inspection of the heat exchange processing apparatus, similarly, only the helical tube cannot be removed, so that it is difficult to easily perform a leak test of the heat exchange processing fluid from the helical tube. Had.

Accordingly, an object of the present invention is to make it possible to efficiently and appropriately clean a helical tube for transferring a heat exchange processing fluid in this type of heat exchange processing apparatus.

In order to achieve the above object, according to the present invention, there is provided a tank having an opening closed by a removable lid, and a tank for storing water therein; A first straight tubular portion protruding outside of the tank through an opening formed in the body, and projecting outside the tank through an opening formed in a component plate of the tank on a side facing the open portion; A heat exchange treatment fluid comprising a second straight tubular portion, and a helically formed helical tubular portion between the first straight tubular portion and the second straight tubular portion and housed in the tank. And a water temperature adjusting means for heating or cooling the water stored in the tank, and the first straight tubular portion and the second straight tubular portion are each provided with a sealing member. To close the opening from the inside A flange is formed, and a stud bolt is provided on the flange so as to protrude to the outside of the tank through a hole formed at the opening edge of the opening and to fasten a nut to a portion protruding from the hole. And the pipe ends of the first straight tubular portion and the second straight tubular portion each constitute a transfer path for transferring the heat exchange processing fluid between the guide tubes. However, the configuration is such that the connection is separable.

According to such a configuration, (1) the pipe ends of the first straight tubular portion and the second straight tubular portion are separated from the tube ends of the transfer pipes constituting the transfer path. Then, (2) by removing the nut fastened to the stud bolt provided on the flange provided on the first straight tubular portion,
The first straight tubular portion can be disassembled with the seal member and the lid, and (3) the stud bolt provided on the flange provided on the second straight tubular portion can be attached to the stud bolt. By removing the tightened nut, assembly of the second straight tubular portion with the sealing member and the component plate of the tank can be released.
(4) Since both straight tubular parts disassembled in this way are configured to form a straight tubular shape, the first straight part provided on the lid is lifted up by the lid. The first straight tubular portion can be easily extracted from the opening from which the tubular portion has been protruded, and (5) the lid is lifted in this way to remove the lid from the open portion of the tank. Thereafter, by pulling the guide tube upward, the second straight tubular portion provided on the component plate of the tank is smoothly extracted from the opening from which the second straight tubular portion has been projected. Can be
(6) Thereby, the guide tube provided with the spiral tube can be easily extracted from the tank.

In other words, according to the heat exchange processing apparatus of the present invention, only the guide tube having the spiral tube for transferring the heat exchange fluid is easily taken out of the tank and provided with the spiral tube. Can be immersion-washed, etc., even if the heat exchange treatment fluid is a food or the like, the food or the like in a state where the hygiene of the food or the like is easily ensured. On the other hand, a desired heat exchange treatment can be performed.

[0010] Further, it is possible to perform a liquid leakage inspection or the like on the guide tube body provided with the spiral tube portion by itself, thereby reducing a burden on maintenance and inspection of the heat exchange processing device.

According to this configuration, after the guide tube provided with the helical tube is washed, etc., (1) the opening provided in the component plate of the tank is inserted through the seal member through the seal member. The second straight tubular portion is inserted into an opening provided in a component plate of the tank so as to be closed from the inside by a flange provided on the second straight tubular portion, and a nut is fastened to a stud bolt provided on the flange, and ( 2) Inserting the first straight tubular portion into the opening of the lid so that the opening provided in the lid is closed from the inside by the flange provided in the first straight tubular portion via the sealing member;
The open portion of the tank is closed by the lid, and then the nut is fastened to a stud bolt provided on the flange of the first straight tubular portion, so that water does not leak from the tank. (3) Thereafter, the pipe end of the first straight tubular portion protruding outside the tank in the guide tube thus reassembled. And, by reconnecting the pipe end of the transfer pipe constituting the transfer path to the pipe end of the second straight tubular portion, the transfer path of the heat exchange processing fluid is again appropriately placed in the heat exchange processing apparatus. Can be formed.
