Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a solidified oil melter for melting solidified oil.

[0002]

2. Description of the Related Art Edible oils such as shortening oil and lard used in fast food restaurants and restaurants are used by melting a solidified oil with a predetermined device.

A throw-in heater is usually used as this type of equipment. The throw-in heater has a handle portion and a heating element integrally formed from the handle portion. The heating element is formed by bending a sheathed heater into a desired shape such as a large spiral shape or an annular shape. And, in this heater, the heating element is put into the container of the solidified oil,
The heat of the heater melts the solidified oil into a liquid state.

[0004]

However, such a device has the following problems. First, the heating element has to be inserted into the solidified oil at the time of initial charging, but the solidified oil is surprisingly hard, which takes time and effort.

Since heat is transferred to the oil in the solidified state through the melted oil around the heating element, it takes time to melt.

Since the surface temperature of the heating element itself becomes extremely high and only the oil around it is constantly heated (for example, in the case of 1 kW, it approaches 210 degrees c after about 70 minutes of energization), the oil in this part It promotes the burning (oxidation) of the oil and causes deterioration of the oil quality.

Since the temperature of the oil tends to be high, it is not only impossible to use a bare hand for holding the can, but it is dangerous if the can falls during heating.

Further, since the heating element is in direct contact with the oil, if the heating element is dirty, it is not hygienic.

An object of the present invention is to eliminate the above-mentioned problems that a conventional melting machine using a throw-in heater has. That is, the present invention is to provide a new type of melter for solidified oil that does not require insertion work, is hygienic, safe, and can melt oil in a short time without causing oil burn.

Another object of the present invention is to provide a new solidifying oil melter with an accessory for melting the oil more efficiently.

[0011]

The features of the present invention are as follows. That is, this solidified oil melter comprises a heat transfer plate and a clamp means. The heat transfer plate contacts the outer surface of the solidified oil container to melt the solidified oil. The clamp means presses and fixes the oil container to the heat transfer plate.

Specifically, a heat transfer plate base for supporting the bottom surface of the solidified oil storage can and having a heater for heating the storage can from the bottom is provided, and the heat transfer plate base is raised to one side. One end of the left and right arm members is pivotally supported by the support column, and the other end of these arms is clamped at the upper end of the storage can placed on the heat transfer plate base to press and fix the storage can to the heat transfer plate base. Clamping means may be provided.

Further, it is preferable that the solidified oil melting machine having the above-mentioned structure is provided with a stick member for forming a through hole extending from the upper side to the lower side in the solidified oil. It is desirable to attach a heater overheat prevention mechanism to the heat transfer plate.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail based on the illustrated embodiments. 1 and 2 are a side view and a plan view of a solidified oil melter according to an embodiment of the present invention. In the figure, reference numeral 1 is a heat transfer plate base, which is composed of a base 2 and a heat transfer plate 3 disposed thereon. The heat transfer plate 3 supports the bottom portion 4a of the solidified oil storage can 4, has a contact area sufficient to obtain good heat transfer, and has a heater 5 installed therein. In general, since the accommodating can has a rib on the outer periphery of the bottom portion, it is desirable that the upper surface of the heat transfer plate 3 be sized to contact the bottom surface in the rib.

A column wall 6 is erected at one end of the base 2 in the figure, and a control panel 8 having a switch 7 for controlling ON / OFF of the heater 5 is attached to the upper end of the column wall 6. In addition, the heat transfer plate 3 is provided on the front surface of the pillar wall 6.
There is provided a safety switch 20 for bringing the heater 5 of the heat transfer plate 3 into a conductive state when the outer peripheral surface of the storage can 4 placed on the contact is pressed by contact.

On the left and right sides of the pillar wall 6, arms 9, 9 whose upper ends are pivotally supported by the side surfaces of the pillar wall 6, are suspended. A clamp 10 is attached to the lower end of each of the left and right arms 9, 9.

The clamp 10 is for fixing the oil containing can 4 placed on the heat transfer plate 3 while pressing it from the upper side to the lower side. Although the structure of the clamp 10 is not particularly limited, for example, the structure shown in FIGS. 4 and 5 is adopted. A can 11 that is hooked on the upper end of the oil storage can 4 and an operation piece 12 is pivotally supported by a spring so that it can be pressed against the upper wall surface of the oil storage can 4 in the clamped state at the inner end of the operation piece 12. The pressing piece 13 is provided.

FIG. 3 shows a Hall stick 14 which is used in combination with the solidified oil melter having the above construction. The hole stick 14 has a rod-shaped portion 16 having a small diameter and a length equal to or larger than the height of the oil container 4 at the tip of the grip portion 15. The rod-shaped portion 16 is provided with a scale 17 indicating the amount of oil.

The state of use of the solidified oil melting machine will be described. First, the oil container 4 is placed on the heat transfer plate 3 and the left and right arms 9 and 9 are lifted. Clamp 10
When the operating piece 12 is pushed in the direction shown by the arrow in FIG. 4, the can pressing piece 13 causes the can holding piece 13 to move to the outer wall surface of the oil storing can 4 as shown in FIG. The bottom of the oil containing can 4 is pressed against the surface of the heat transfer plate 3 and fixed by pulling the above-mentioned spring not shown.

In this state, when the switch 7 is turned on, the heater 5 is energized to start heating the oil container 4 in contact with the heat transfer plate 3 from the bottom. The heat heats the bottom of the solidified oil through the wall of the can, so that the solidified oil melts from below. Therefore, the solidified oil is melted more quickly than the conventional throw-in type heater, in which heat tends to go upwards. Part of the heat from the bottom is also transmitted to the side wall of the oil container 4 so that the solidified oil is more efficiently melted.

The hole stick 14 is used to open a hole 18 which almost penetrates the solidified oil S from top to bottom before or immediately after the heater 5 is energized. Generally, the bottom of the oil container 4'swells in a convex shape as shown in FIG. 6 due to the weight of the solidified oil. Therefore, the clamp 1
Even if 0 is used, the entire bottom of the can often does not contact the heat transfer plate 3. The clamp 10 presses the container 4 ′ against the heat transfer plate, but cannot flatten the bottom until the solidified oil at the bottom of the container melts to some extent. Therefore, even if the heater 5 is energized in such a state, only the center of the bottom of the can 4 ′ locally becomes high in temperature, which easily causes oxidation of the oil S and causes heat loss of the heater 5. By opening the hole 18 with the hole stick 14 (see FIG. 7), the oil L melted at the bottom of the can moves to the upper surface of the solidified oil S through the hole as shown in FIG. As a result, the entire bottom of the can comes into contact with the heat transfer plate 3 as seen in FIG.

Further, the heater 5 can prevent an excessive temperature rise by setting an energization time (heat time) in advance. At the same time, after the heat time, the heater 5
By setting the control so that the remaining solidified oil is melted by the heat storage of the oil and the heat storage of the oil itself, the temperature of the oil does not become excessively hot, and the outer wall of the can can be maintained at a temperature that can be touched with bare hands immediately after the oil melts. Immediately after lowering the temperature, the surface of the heat transfer plate will be at a temperature that will not cause burns, and the electricity bill can be saved.

[0023]

As described above, according to the present invention, the oil containing can is pressed and fixed to the heat transfer plate by the clamp means, so that the work of inserting the heating element into the solidified oil becomes unnecessary. Not only can the solidified oil be melted efficiently, quickly and hygienically from the bottom.

Further, since the solidified oil is heated through the wall of the can, it does not need to be heated to such a high temperature and oxidation is less likely to occur.

It is not necessary to keep the oil temperature high,
Since the oil container can also be firmly fixed to the heat transfer plate via the clamp, there is no risk of the container can tipping over or causing burns due to the hot oil inside.

Further, by using a rod-shaped material for making holes in the solidified oil, the entire bottom of the can can be surely brought into contact with the heat transfer plate, and the solidified oil causes an efficient and economical loss. It can be melted without.
