Description

Circulation-heated food extractor}

The present invention relates to a circulation-heated food extractor.

Generally, food extractors of various structures are used to make extracts containing useful ingredients contained in foods by boiling them with water.

In a conventional food extractor, a heater or a burner is disposed at a lower portion of a body containing food and water, thereby heating the water by continuously heating the lower portion of the body, thereby extracting useful components contained in the food into water.

However, in such a case, as the lower part of the main body is continuously heated, the food contained therein may be deteriorated and adhered, which may destroy useful components of the food.

Therefore, in recent years, there has been developed a food extracting apparatus for indirectly heating the food so that the food is deteriorated and is not easily adhered to the food.

As a conventional technique for the above-mentioned purpose, there is an indirect heating type medicinal liquid extracting apparatus of Patent No. 0908840. In this medicinal liquid extracting apparatus, the heating medium is indirectly heated by circulating the heating medium through the circulating flow path (See Patent Document 1).

However, in the above case, it takes a lot of time to heat the water in the hot water pot. To this end, a lot of heat energy is used to heat the heating medium, which results in a problem that energy efficiency is greatly reduced.

Therefore, in order to prevent the deterioration of the extract, it is required to develop a food extractor with high efficiency of using heat energy while indirectly heating the extract.

<When extracting blood extract>

The user places water in the inner container 11 of the main body 10 together with an appropriate amount of extract and sets the temperature using a controller (not shown).

When the extraction is started, the heating medium is heated by the heater to the set temperature.

When the heating medium is heated to the set temperature, the heating medium circulation pump 62 is operated so that the heating medium is circulated along the heating medium circulation line 50 via the outer vessel 12 of the main body 10 and the heat exchanger 40 .

At the same time, the circulation pump 30 is activated, whereby the extract liquid contained in the inner vessel 11 is circulated through the heat exchanger 40 along the extract liquid circulation line 20.

While the above process is continued for a predetermined period of time, the extract circulated through the main body 10 and the heat exchanger 40 is kept heated to an appropriate temperature, extraction of the blood extract proceeds, and then the operation is stopped.

<Operation mode of cleaning and disinfection mode>

When the extract circulating line 20 is washed, the extract liquid remaining on the inner vessel 11 and the extract circulating line 20 is discharged and removed. Then, an appropriate amount of water is put into the inner vessel 11, Select the mode or cleaning temperature.

When cleaning is started, the heating medium in the heater is heated to the set temperature.

When the heating medium is heated to the set temperature, the heating medium circulation pump 62 is operated so that the heating medium is circulated along the heating medium circulation line 50 via the outer vessel 12 of the main body 10 and the heat exchanger 40 .

At the same time, the circulation pump 30 is activated, whereby the water contained in the inner vessel 11 is circulated while being heated by the heating medium.

Then, the pressurizing device 70 is operated to raise the internal pressure of the liquid circulation line 20 to a saturated vapor pressure or more, thereby raising the boiling point of the washing liquid.

The washing liquid whose boiling point has been raised is heated by the heating medium to a temperature of 100 ° C or higher (preferably 150 ° C or higher), circulated for a certain period of time along the liquid circulating line 20, .

When the washing is completed, the washing liquid is discharged from the extracted liquid circulating line 20 and the inner vessel 11 of the main body 10, and the washing is completed.

The steam sterilization extractor 80 is operated so that the high temperature steam is generated to fill the interior of the liquid circulation line 20 and the inner container 11 of the main body 10. [

In this state, the liquid circulating line 20 and the inner container 11 of the main body 10 are sterilized by being held for a predetermined time.

As described above, according to the present invention, since the extract liquid is circulated along the extract liquid circulation line and the small amount of the extract liquid is heated through the heat exchanger, heating of the extract liquid is easy and fast and the heat energy is used up because the heat medium heats the body together.
