Description

  In general, in the present invention, when the treatment liquid is heated, bubbles are generated, and the quality may deteriorate due to inclusion in the solution. Therefore, the present invention relates to an apparatus for heating the processing liquid which is stabilized in food hygiene by stabilizing the component concentration without adding an antifoaming agent when heating the processing liquid and applying a bactericidal action.

For example, soy milk is a health food, so demand has recently increased. For this reason, there is a strong voice from consumers that it is better not to use additives as much as possible in terms of safety, hygiene, and the like, and consumers or consumer cooperatives are demanding no additives.
In the conventional heating method, bubbles are blown out in the open type, and in order not to blow out, the work efficiency is poor with a complicated structure and a small capacity (see Patent Document 1).

  The biggest problem in processing a slurry, emulsion, liquid, etc. at high temperature is that the process liquid is not burned and the active ingredients of the process liquid are affected. It is whether it is possible to completely remove the unpleasant odor without giving it, and to add fragrance and deep body. Furthermore, in the heating of the treatment liquid, bubbles are generated, and bubbles and the like are mixed into the product. Therefore, an antifoaming agent is often used. However, it is not preferred in terms of inclusion of additives.

In order to solve this problem, a solution has been studied by using a stirrer in a heating kettle, but it does not provide a sufficient solution. In addition, even in products such as soy milk, there is not yet a satisfactory treatment method that can provide sufficient aroma and deep body. Therefore, the present condition is that an antifoaming agent is added.
In addition, as a heating device for processing liquid such as slurry, emulsion, liquid, etc., a jacket or a steam injection device has been proposed. Also, defoaming by impellers by sucking bubbles has been proposed. The original taste is drawn out, and there remains a problem with temperature uniformity at high temperatures (see Patent Documents 3, 4, 5, and 7).

  In addition, a double hook with a jacket is used to make the temperature uniform, but it takes time only by indirect heating of the jacket portion, the workability is poor, and some products cannot be used when heating for a long time. In particular, in the case of kure soup, indirect heating alone is inappropriate because it causes burns over a long period of time. (See Patent Document 6)

JP 2000-228970 A JP-A-11-89722 JP-A-5-268900 JP 58-19936668 JP 2001-054364 A JP-A-63-141557 JP 2003-235490 A

Conventionally, many antifoaming agents (quality improving agents) or the like are used for foam generation when heating a slurry, emulsion, liquid, or other treatment liquid in the production of soymilk or the like. Therefore, it is difficult to bring out the original taste of the raw material.
In addition, a kettle that heats kure soup in the soy milk and camellia flower production apparatus has been proposed, but the generation of boiled soup bubbles was prevented, and the concentration of soy milk was unstable and unpleasant odor (blue odor) could not be completely removed In view of the fact that the fragrance and richness could not be satisfied, and in general, the okara camellia flowers were used as luggage for tofu production and were disposed of as industrial waste. Has come to be expected. However, there is concern about the spoilage that is the original characteristic of camellia flowers, and there is a need to develop a device that is stable and has a long shelf life. Furthermore, an apparatus that does not generate bubbles during heating is also expected.

  The present invention stabilizes the component concentration and removes bubbles from the product by adding an antifoaming agent that is usually used when heating a treatment liquid such as slurry, emulsion, or liquid. An object of the present invention is to provide an apparatus for producing a safe product that completely removes an unpleasant odor and is fragrant and rich.

In order to heat processing liquids such as seasonings, drinking water, soy sauce, dairy products and fermentation products without using an antifoaming agent, etc., the temperature is increased and bubbles in the processing liquid are increased. And the processing liquid is easily separated, and pressure is applied from the set temperature while discharging air and unpleasant odor from the heating kettle, and the generated foam component is completely heated and erased. By doing so, we propose a heating device that provides a safe and delicious raw material.
In the present invention, the treatment liquid is put into a heating kettle and directly heated and indirectly heated (from the jacket portion), and at the same time, the agitator is turned and suction is started by a suction device. At that time, the kettle is sealed and heated in a vacuum state. When the set temperature is reached, the suction device is stopped and aging is carried out (around 1 to 10 minutes).
Similarly, the treatment liquid is put into a heating kettle and directly heated and indirectly heated (from the jacket portion), and at the same time, the stirrer is turned and cooked open until the set temperature (around 80 ° C.) is reached. Thereafter, only heating is stopped, the container is sealed, and evacuation is started by a suction device. After the set time, heating is started again, and when the set temperature reaches 2, the suction device is stopped, and aging (simmering) is performed by opening or closing (around 1 to 10 minutes).

  In the present invention, the treatment liquid is heated directly after being contacted with superheated steam at 100 ° C. to 550 ° C. while performing stirring and vacuum suction operations in a heating kettle that can be heated indirectly and directly. Allow 1 to 20 minutes for aging at the final stage. In particular, the treatment liquid is brought into direct contact with superheated steam at 100 ° C. to 550 ° C. in a sealed state in a sealed double jacket with a heating jacket, and an aging process is provided at the final stage. It is particularly important to perform the operations of stirring and vacuum suction. The final aging step is 75 ° C. to 130 ° C., and preferably about 1 to 10 minutes.

When the slurry is filled into the double heating kettle from the treatment liquid inlet such as emulsion, liquid, liquid, etc., it enters the jacket part from the steam pipe and indirectly heats, further heats directly through the launch pipe, and at the same time rotates the stirrer, Entrain the floating bubbles in and heat the treatment liquid and the bubbles together. When the set temperature is reached, an unpleasant odor inside the kettle is evacuated by a suction device simultaneously with stirring. As a result, the bubbles and the processing liquid are easily separated, and the bubbles disappear.
Air and unpleasant odor are sufficiently discharged until the set temperature (85 ° C. to 98 ° C.) is reached, the suction device is stopped, the suction port is closed, and the pressure is applied. Thereby, the heat aging is sufficiently performed on the foam which is not completely cooked to obtain a stable and uniform treatment liquid, and the heating steam and the stirrer are stopped. Thereafter, the processing liquid discharge valve is opened to discharge the processing liquid.
It becomes a safe and uniform treatment liquid that has been heat-aged without the addition of an antifoaming agent, and the original delicious product can be obtained.

According to the present invention, in a stable product manufacturing apparatus capable of defoaming, an agitator with a superheated steam injection pipe installed therein, a suction device additional heat double heating kettle (with a jacket), and a superheated steam at 100 ° C. to 550 ° C.
