Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a frying machine for commercial use, and more particularly to a pot for a frying machine that continuously cooks a predetermined amount of frozen food for deep-frying and serves it in cups. .

The frying machine according to the present invention is a machine that is configured to be activated by inserting a coin or a substitute currency, and can immediately provide fried foods on demand. These foods may be foods that can be frozen and fried in oil, such as chips, other fish cakes, and frittata.

Although commercial fryers such as those described above already exist, their use has not yielded satisfactory results and they have had little commercial success. There are many reasons for this, not least of which is the exposure of the frying oil to air and light.

The frying machine according to the present invention eliminates these drawbacks.

In the deep frying machine according to the invention, the deep fryer is formed with a hermetically sealed enclosure which holds the food in a perforated basket which is used to submerge the food into the oil of the pot. The porous basket has a side door for loading and unloading, and the upper part of the perforated basket extends toward the door to form a deflector, and the deflector is integrated with the door, and the opening operation of the door causes the deflector to open. At least a portion of the housing is configured to protrude outside the surrounding body.

The advantage of this arrangement is that the bottom of the deflector and the door are of equal size, and the lower end of the door is swingably attached to the wall of the enclosure.
As a result, the frying pan opens outward only when loading or unloading food into the basket. Since the movement of the basket is linked to the movement of the door, there is no need to provide a special mechanism for removing the basket from the pot.

In known frying machines, an unsealed pot is housed in a cabinet, the cabinet having means for communicating air between an air inlet and an air outlet formed in the wall of the cabinet; It is equipped with a filtration device in the discharge circuit.

The ventilation means used for this purpose sucks in the surrounding air, flows it around the oil being used, and then discharges it back into the surrounding area, but the amount of air flowing through is large and the filtration device is insufficient. In many cases, contamination cannot be avoided.

According to the invention, the exhaust air circuit is connected to the air intake downstream of the filtration device, so that the air exposed to the frying process is not exhausted to the surroundings. While this air flows through the closed circuit,
After passing through the surface of the frying oil, the oil contained therein is removed by a filtration device. In this device, the air throughput is small and filtration is effective. Water vapor emanating from the food during frying is condensed outside the pan and removed before air is recirculated.

There is no need for filtration devices to remove odors in the recirculated air. This is because such odors can be significantly reduced by paying attention to the storage conditions of the oil, and the odor will never be noticeable outside the closed pot.

In the known machine, the frozen food to be fried is stored in an insulated compartment and maintained at a suitable temperature;
and is discharged by a hopper. At this time, the food falls into a hollow measuring means inside the cylindrical member that closes the opening of the hopper, and one serving of food is measured by volume measurement, or Weighing is performed either by dropping onto a weighing pan and measuring its weight.

The machine of the invention belongs to the second type mentioned above.

More specifically, a unit for storing frozen foods and continuously weighing their serving quantities has an insulated and sealed compartment maintained at an appropriate temperature, which compartment is: The structure is as follows. namely, a storage for frozen foods which is open above the conveyor means, a conveyor means for receiving the food products coming out of the storage and transferring them to the receptacle of the balance, and a storage for receiving the articles to be weighed. a balance having a receiving tray and including a discharge means which opens above an opening formed in the wall of the compartment; means for controlling the advancement of the conveyor means in accordance with instructions given by said balance; and means for controlling the operation of the means for causing the tray of the balance to perform a discharging operation in response to a request.

In a preferred embodiment, the tray of the balance is formed in the form of a basin, the bottom of which is formed by abutting the free ends of the dividing elements forming the tray, these elements being aligned with each other (in the weighing position). It is swingably mounted so that it can be moved closer (to a position where weighed food is discharged) or moved away (to a position where weighed food is discharged).

Thus, the weighed food will fall naturally from the bottom of the open dish and will not be crushed by any moving parts.

Next, an embodiment of the present invention will be described with reference to the accompanying drawings, which does not limit the scope.

The frying machine shown in Fig. 1 has a unit (fifth unit) for storing and distributing frozen foods as its main part.
Figure). Furthermore, this frying machine has a continuous predetermined amount measuring means (Fig. 6) that calculates a predetermined amount of food based on its weight and puts the measured amount of food into a deep-bottomed deep-bottomed basket for frying, and an oil reservoir. It has a tank 3 (Fig. 1) and a frying pan 2 (Fig. 1) supplied with oil from the oil storage tank 3 (Fig. 1).

The various components mentioned above and their functions will be explained below, but first, the "fried cooking machine" will be explained.

In Figures 1 and 2, the deep fryer 2 has a door 5.
It constitutes a sealed enclosure through which items can be taken in and taken out. A silicone seal is fitted into the contact area between the door 5 and the opening of the pot 2 that is closed by the door 5. The bottom of the pot 2 is provided with an oil supply port 6 and an oil discharge port 7, as clearly shown in FIG. The oil supply port 6 is equipped with a valve 8, which is connected to the pot 2.
opens only under the action of externally applied positive pressure. A filtration device 9 is also provided on the outlet 7, and the filtration device has a handle 10 for removing it. At the top of deep frying pan 2,
An intake hood with a replaceable oil removal filter 12 is provided and is connected to the turbine 13. The outlet of the turbine 13 is connected to an opening (not shown) provided in the middle of the pot 2. A device for condensing and removing water vapor is arranged in the connecting duct (not shown). The pot 2 houses a deep-bottomed basket 1 for frying, and the bottom 14 of the basket is made of a coarse grid. On the same side as the door 5, the basket is provided with a stainless steel extension forming a deflector 15. The bottom of the deflector 15 is flat and has the same size as the door 5, and is fixed to the door 5. That is, the basket 1 and the door 5 are integrally constructed. The lower end of the door 5 is pivotally attached to the wall of the pot 2. The door 5 is opened by a pair of jacks 16 and 17 (FIG. 4). The jack 16 moves the door 5 between the closed position and the position P1 (FIG. 1), and the jack 17 moves the door 5 between this position P1 and the position P2.
(Figure 1). When the door 5 is closed, the silicone seal is compressed within the housing provided for this seal by the pressure applied by the jack 16.

The oil reservoir 3 has a cylindrical shape, and a piston 18 slides inside thereof under the action of a jack 19. An oil discharge port 20 and an oil re-immersion port 21 equipped with a valve 22 are provided at the bottom of the storage tank 3.
is opened only when negative pressure is applied within the storage tank 3. The oil discharge port 20 of the storage tank 3 is connected to the oil supply port 6 of the pot 2 by a duct 23, and the oil discharge port of the pot 2 is connected to the oil refill port 21 of the storage tank 3 by a duct 24.

The duct 23 passes through the duct 24, and the duct 24 forms a sleeve.The duct 24 is equipped with an electric heating means at the bottom to heat the oil to a temperature suitable for frying. temperature is determined by thermostatic means 26. Additionally, a safety thermostat (not shown) is provided to interrupt heating if the oil overheats.

The level of oil in the storage tank 3 is kept constant by proper storage amount holding means R (FIG. 2).

As can be seen from FIGS. 5 and 6, the unit for storing and weighing frozen foods consists of a compartment 27 equipped with insulation 28. Freezing means 36 is provided to maintain a temperature suitable for preserving frozen foods, for example -18°C, and the compartment 27 is provided with a side door 2.
By opening 9, the storage container 30 therein can be taken out. This container 30 slides within an interlocking sliding device 31. The bottom of container 30 forms a hopper 32 which has an opening above conveyor belt 33 (FIG. 6).

A food outlet opening 34 is formed at the bottom of the compartment 27. This opening 34 has a rotatable trap 35.
It can be closed by

A balance 37 is provided in the compartment 27, the beam of which oscillates about an axis 38 and has a weight 39 in one arm and a saucer 40 in the other arm.

The above-mentioned weight is selected according to the weight of one cooking batch of frozen food. On the arcuate trajectory traced by the end of the arm carrying the weight, switch means 41 are provided which act on a circuit for controlling the progress of the conveyor belt 33.

A tray 40 located vertically below one end of the conveyor belt 33 is formed of two members 40a, 40b that can move toward and away from each other. In the closed position (abutment position), these parts form a receiving container for the food product falling from the conveyor belt 33. Their movement away is effected by external action, for example by inserting a coin into the appropriate control device.

The opening 34 of the compartment 27 has the door 5 at position P1.
, it is located vertically above the deflector 15.

This deflector, when in position P2, is directed toward a cup (not shown) coming from a cup dispensing unit (not shown).

The operation of this fried cooking machine is as follows.

A pre-weighed serving of food is provided on a balance tray 40 in a storage weighing unit. The deep fryer 2 is closed and empty inside. The oil reservoir piston 18 is at the top of its stroke and the duct 23 is filled with oil. The electric heating means 25 is energized and maintains the temperature of the oil at about 180°C.

When the user desires food, he activates the various mechanisms of the deep frying machine either by pressing a button or by inserting a coin or token into the appropriate device.

As a result, the piston moves down inside the reservoir 3,
The oil is discharged into the duct 23. Under the action of pressure, the supply port valve 8 opens, and oil at 180° C. is supplied into the deep frying pan 2. When the piston 18 reaches the bottom of its stroke, the biasing pressure on the valve 8 is removed and the valve 8 closes again. Simultaneously with the piston, a turbine begins operating, which circulates air within the closed circuit and filters the air as it passes through the closed circuit.

Furthermore, at the same time, Jack 16 moves door 5 into position.
P1 tilts the basket 1 so that its deflector 15 is located vertically below the opening 34 of the food storage unit. Then, the trap 35 rotates, and the single serving of food that has been supported on the tray 40 of the balance falls into the basket 1. The two parts 40a, 40b of this balance pan separate at the same time as the trap opens. Then Jacky 16 closes door 5 again,
At the same time, basket 1 and its contents are immersed in frying oil.

Cooking will be completed in about 40 seconds. The piston 18 rises again, sucking in the frying oil via the filtering device 9 covering the outlet 7 of the pan 2, which passes through the duct 24 and, by pushing back the valve 22, through the opening 21. Then, it re-enters into the storage tank 3.

While emptying the pot 2, the fried food is drained of oil. The jack 16 and then the jack 17 push the door 5 to position P2 and the fried food falls from the basket 1 into the prepared cup.

The jack 17 and then the jack 16 close the door 5 again.

During this time, the circuit of the conveyor belt 33 is switched on and the frozen food falls into the tray 40 of the balance 37 until it reaches the amount determined by the weight 39. When the predetermined weight is reached, the conveyor 33
stops, and a new batch of frozen food is placed in tray 40.
Remains prepared on top.

The turbine 13 is stopped, and the deep-fried cooking machine is thus ready to start operating again.
