Description

Fryer EQUIPPED WITH COOLING MEANS FOR DREGS COLLECTION WATER}

The present invention relates to a frying apparatus having a bottom waste collection layer and an upper oil layer,

More specifically, the present invention relates to a frying apparatus which introduces a forced cooling means for collecting water to lower the temperature of the cooling water to about room temperature (or lower) to prevent microbial propagation as well as to prevent deterioration of oil.

Using the principle of specific gravity difference, the fryer having the bottom waste collection layer and the oil layer on the top has been commercially used for a long time.

In Korea, Utility Model Publication No. 1992-0005900 (April 21, 1992) [Food Frying Machine] and Utility Model Publication No. 1992-0008915 (June 16, 1992) [Frying Machine]

They employ a method of introducing a cooling pipe for air cooling as a cooling method of the collection layer.

In addition, Utility Model Registration No. 0162623 (September 20, 1999) [Frying Machine] forms a cooling space for a separate bath effect outside the frying tank where the collection layer and the oil layer are formed to cool the collection layer by water cooling. It is presenting technology.

However, in either case, due to the limitation of the cooling method by heat exchange, the water temperature of the collected water rises to about 40 ~ 70 ℃.

Due to this, it forms a favorable condition in the growth of microorganisms due to the residue of fried flour and water temperature, thus providing an unhealthy cooking environment,

The problem of collection corruption is the problem that has to be solved urgently because it is transferred to the oil layer and causes the corruption of oil (causes food poisoning and bad taste, smell and color of food).

After a certain period of time, the oil layer is first discharged to completely remove impurities such as debris from the used oil and to replace the collection water.

In general, drainage is provided at the top of the collection layer and the oil layer to drain the oil.

However, if the oil is released shortly after cooking

As the draining time elapses, hot oil, which has been heated to a suitable cooking temperature of 160 ~ 220 ℃ in the upper part of the oil layer, comes into contact with the collection water.

Sudden heating of the collection water occurs, causing problems such as oil and water mixing or water splashing due to convection.

It was dangerous and uncomfortable.

On the other hand, except for the initial oil, the oil is produced during the heating and cooking process of the trans fatty acid (benzopyrene), so even if you start cooking with oil without trans fat, the trans fatty acid is produced proportionally as the number of cooking increases. Trans fatty acids are bound to remain.

Therefore, the frying method used by re-heating the oil is difficult to maintain a constant taste of the cooked product, and is also a form of alternating oil depending on the arbitrary criteria of each user, so it is practically impossible to provide a consistent and standardized food to customers. .

For this reason, customers are becoming increasingly distrustful of frying oil and cannot meet the current method of change in the age of well-being, taste and freshness.

In particular, in the fried food franchise industry, different stores have different usage time standards, and there are sensory, nutritional and hygienic differences between the early and later cooked foods. As taste turns color into black color, there is a difference in product quality before and after oil exchange, which makes it impossible to control uniform cooking quality, resulting in lack of competitiveness or self-offset factor.

On the resource side, however, throwing away fried oil and adding new ones is costly and economically costly.

Accordingly, in the technical field, there is a demand for technology development to provide a frying apparatus having a function of removing impurities such as sludge contained in oil.

In order to meet these demands, in particular with respect to the oil filtration means that can be recycled by removing impurities such as residue such as fried flour from the oil already used in the commercial frying machine

In addition, it is to cover all of the forms directly connected or separated separately through the frying tank and drain,

The term "frying apparatus with oil filtering means" does not mean that the filtering means and the collection tank and the frying tank are physically connected (particularly mounted in the same housing).

The bottom portion of the frying tank 10 forms an inclined portion 10A (see FIG. 2 [C]), and above all, a drain hole 15 for discharging the collecting layer L2 for foreign matter such as a lower residue when cleaning the frying tank. It is preferable to have the inclination and the shape which is pointed toward ().

Compared to the heating means (20) embedded in the oil layer (L1), the cooling pipe 31 constituting the cooling means 30 is located at the interface between the oil layer (L1) and the collection layer (L2), but the collection layer (L2) It is preferable that the shape is more buried in (the separation of the oil layer (L1) and the collection layer (L2) is arbitrarily divided into the one-dot chain line display part of Fig. 1 and the one-dot chain line of Fig. 2 [C] for convenience of understanding). Display).

Alternatively, the cooling pipes 31 (shown in FIGS. 1 and 2 (shown discontinuously) and FIG. 3 (shown in a continuous zigzag form) differ from one another in structure, but are for convenience only. Irrespective of the protection scope) is replaced by a refrigerant circulation passage provided on the outer wall of the frying tank 10,

As shown in the drawing, the drain is located near the interface between the first drain 11 for discharging the hot oil in the upper part and the second drain 13 for discharging the hot oil in the lower part near the interface between the oil layer and the collection layer. Done,

More than three drains may be introduced as needed.

In particular, the upper first drain 11 is partitioned by a partition 17 partitioning the oil layer L1 receiving portion in the frying tank 10 into two or more (commonly referred to as two-sphere, three-sphere, etc. in the industry). Each drainage space FS (two in the figure) is provided with a drain port 11A (two in the figure) connected to the upper first drain 11 separately to form a pipe.

In addition, the heating means 20 is turned on / off separately for each of the frying space (FS) partitioned by such a partition wall 17 to heat only the necessary frying space (FS) to increase the thermal efficiency,

In addition, if necessary, a frying mesh 19 or skewer fixing clamp (not shown) may be provided for various frying dishes.

Each frying space is preferably provided with a temperature sensor (not shown) to enable the temperature control of the heating means 20 in the operation panel C1 (see FIG. 1) provided at the upper front.

In addition, the insertion depth of the barrier 17 is preferably up to the second drain 13.

When all the hot oil is discharged by opening the first drain (opening of the valve 11v provided in the pipe constituting the drain), the low temperature oil is then discharged through the second drain 13 (to the pipe constituting the drain). Open valve (13v) provided,

The discharged oil is collected in the collection tank 40.

After discharging the oil layer L1, the valve 15v provided in the pipe forming the drain port 15 is discharged in order to discharge the collection layer L2 in the frying tank 10, and put the frying tank into a separate container. Empty it completely.

Next, a frying apparatus (F) having an oil filtration means according to the present invention will be described.

As shown in FIGS. 6 and 1 and 2, which are two-dimensional views, the frying tank 10 and the collecting tank 40 are connected through the drains 11 and 13, and thus, in one housing H. It's built in.

However, as declared above, the protection scope of the present invention is not limited thereto.

Like the frying tank, the collection tank 40 is also preferably provided with an inclined portion 40A having an inclined portion and a shape inclined toward the inclined portion, in particular, the drain hole 41.

Filtration means 50 as the core of the frying apparatus F according to the present invention has a difference in using a float 51 related to the principle of buoyancy,

This filtering means 50 includes a pipe 53 having a suction port 53A, a filter 55 and a pump 57.

The upper oil layer of the collection tank 40 may be suction-filtered at all times so that the body of the filter 55 is not blocked by the foreign matter that is not caused by the float.

In the drawing, the oil intake port 53A of the oil absorption pipe 53 is provided in the float 51,

Floats with various connection structures, shapes, and sizes can be introduced as long as the suction port satisfies the requirement to stay on top of the collection oil at all times.

In addition, it is preferable that the suction port 53A is arranged directly above the drain port 41, since the oil will remain in the upper part of the drain port through the slope 40A until the end of the oil absorption filtration step. .

In addition, in FIG. 6C, the pump 57 connected to the pipe 53 is provided in the pump housing 57h separate from the collection tank 40 so as to provide a suction force at the suction port 53A.

On the other hand, as the filtering process proceeds for filtration regeneration, the amount of oil decreases and the level decreases, or when the amount of oil increases when the oil is added to the initial collection tank 40, the level increases.

If the oil level changes, the float level should change.

At this time, it is preferable that a position adjusting means is introduced into the pipe so that the suction port is in constant contact with oil for oil filtration regeneration.

The position adjusting means may be implemented in various ways, such as simply implemented in a manner using a flexible pipe (may be a flexible pipe may be introduced to a specific portion),

In order to make the suction port 53A stay on the drain port 41 at all times, as shown in FIG. 7.

Preferably, the position adjusting means is a rotational link 59 provided in the pipe 53.

Furthermore, the filtration means 50 of the frying apparatus F according to the present invention introduces a sensor (float sensor, etc.) that can be detected according to the oil level in order to withdraw the foreign matter precipitated in the collection tank 40 at the source. In response to the detection thereof, the pump 57 may be automatically stopped when the suction port 53A reaches the threshold level.

As an example of implementing this, as shown in FIG. 7C, a proximity sensor S, such as a magnetic force sensor, is installed in the rotational link 59,

When the pair of sensors (S) is matched according to the rotational angle of the link (59), the transmission is made and the pump (57) by the controller (the connection between the sensor (S) and the controller (C) is indicated by a dashed line for convenience). Stop the operation.

Depending on the type of sensor, the sensor may detect the oil level and stop the pump if the level detected by the sensor matches the minimum threshold level stored in the microcomputer.

In the above description, the conventionally known techniques related to the frying temperature, the oil decay condition, the temperature control of the heating means, the resources of each component, etc. are omitted, but those skilled in the art can easily infer, infer, and reproduce them.
