SOLUTION: An air needle 51 connected to a pressurized air source is installed in the vicinity of a packing nozzle 52 for thrusting into and stuffing a filling into a pastry of a food to be produced so as to project the tip of the air needle from that of the pacing nozzle in the thrusting direction. When the packing nozzle 52 is thrust into the pastry, the air needle 51 is simultaneously thrust into the pastry and the thrust is swollen by pressurized air from the air needle to stuff the filling into the pastry. Air is introduced from the air needle 51 thrust into the tip of the pastry, the pastry is swollen to separate side walls mutually so as to reduce the danger of the packing nozzle 52 breaking through the side walls of fried bean curd. When the packing nozzle 52 is thrust into the pastry, air can be leaked from the circumference of the thick packing nozzle.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food manufacturing machine and, more particularly, to a method and an apparatus for injecting fillings such as rice cakes, okara, and vegetables into foods forming a soft foreskin such as fried food.

[0002]

2. Description of the Related Art There is a processed food in which rice cakes and vegetables are filled in fried food. When manufacturing this kind of food, the filling nozzle of an automatic filling device is inserted into the fried food fried in a fryer, and the rice cake is cooked. And filling with vegetables and other fillings. The inside of the fried rice is not bagged just by frying, and after frying, insert the air needle and inject air inside.
The inner soft tissue is separated and formed into a bag, and then the filling nozzle is inserted to inject the filling. A device for inserting the air needle into the fryer to inject air and separate the inside of the fryer from the fryer while aligning and transferring the fryer to the filling machine is disclosed in Japanese Patent Application Laid-Open Nos. 42949, JP-A-4-1907
No. 55 and the like.

A filling nozzle of an automatic filling machine is inserted into the frying fried in a bag shape by separating the inside as described above, and the filling is injected. The filling nozzle for injecting the filling injects air. The diameter is much larger than that of the needle. The fried food used as a foreskin for this kind of food is made thin, and is soft and easily bent. For this reason, the tip of the nozzle inserted from the frying edge pierces the side wall of the frying and is exposed to the outside of the frying, and the filling to be poured flows out and becomes a defective product.
Even if air is blown in with an air needle prior to filling, there is also one in tens to hundreds of frying that does not separate inside, making it very difficult to insert the filling nozzle of an automatic filling machine into such frying At the same time, even if it can be inserted properly, a situation in which the foreskin is broken by the filling pressure and the filling material flows out easily occurs.

[0004] As means for solving the above problem at the time of filling the filling material, when inserting a nozzle of an automatic filling machine, both sides of the fryer are sandwiched by members having a concave portion on the opposite surface, and a negative pressure is applied to the concave portion. Spread the frying in the thickness direction,
An apparatus for preventing the tip of the nozzle from piercing the side wall of the fryer is disclosed in Japanese Patent Application Laid-Open No. 8-98665.

[0005]

When the filling nozzle is inserted, in order to realize the technical means of applying a negative pressure to the member holding the fry to expand the side wall of the fry, an opening and closing operation is performed. It is necessary to supply a negative pressure to the holding members, and it is necessary to synchronize the timing of inserting the filling nozzle into the fryer and the timing of applying the negative pressure by some control means. It gets complicated.

[0006] Further, when the filling which has been injected flows out due to incomplete separation of the inside of the fryer, the filling is sucked into the negative pressure generating device. Cleaning and maintenance are very cumbersome.

Further, if the step of injecting air and separating the inside, which is performed as a step prior to the step of injecting the filling into the frying, can be omitted, the structure of this type of food manufacturing apparatus can be simplified.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems. An apparatus for injecting fillings such as rice cakes and vegetables into fried food and other foods forming a soft foreskin has a simpler structure. It is another object of the present invention to provide a method and an apparatus which can reduce the number of defective products as much as possible without requiring cleaning and maintenance.

[0009]

SUMMARY OF THE INVENTION A method for injecting a filling into a soft foreskin according to the present invention is a method for injecting a filling into a foreskin of a food product to be manufactured and injecting the filling into a pressurized air source close to a filling nozzle 52. The connected air needle 51 is provided so that the tip of the air needle protrudes from the tip of the filling nozzle 52 in the insertion direction, and when the filling nozzle 52 is inserted into the foreskin, the air needle 51 is simultaneously inserted. The foreskin is inflated by pressurized air from the air needle to inject the filling.

It is characterized by having. Both a configuration in which the carrier 41 moves the foreskin holding means 42 and a configuration in which the filling nozzle and the air needle are moved are possible.

According to a third aspect of the present invention, in the device of the second aspect, the foreskin holding means 42 is provided with openable and closable sandwiching members 45, 45 arranged opposite to each other. It is provided with a U-shaped holding surface that comes into contact, and the filling nozzle 52 and the air needle 51 are provided toward the U-shaped bottom of the holding members 45, 45.

According to a fourth aspect of the present invention, in the apparatus according to the third aspect, the suction pad 31 for temporarily sucking and holding one of the foreskins of the food to be produced by negative pressure and the filling nozzle 52 for filling are provided. A foreskin holding means 42 for receiving foreskin from the suction pad 31 at a moving end moved in the separating direction, and a carrier 41 for reciprocating the foreskin holding means 42 between the moving end and the filling nozzle side moving end, The suction pad 31 has a peripheral portion 35 protruding toward the foreskin to be held, a suction region 3C slightly recessed from the peripheral portion toward the foreskin side, and a number of suction holes 38 opening to the suction region.

Is inserted before the filling nozzle 52, and air is blown into the fryer from the air needle 51 that has been previously inserted. Therefore, in the fryer in which air is injected in advance and the inside is separated, the air needle 51 is used. The frying is inflated by the air injected from the fridge, the side walls are separated from each other, and then the filling nozzle 52 is inserted, so that the risk of the filling nozzle 52 breaking through the side wall of the fry is reduced. When the filling nozzle 52 is inserted, air can leak from the periphery of the thick filling nozzle, so that a situation in which the foreskin further expands and breaks when the filling is filled does not occur.

Further, since air is injected into the foreskin prior to filling of the filling, the separation of the inside such as frying and filling of the filling can be performed without providing a step of injecting air and separating the inside in advance. Operation can be performed, and the device structure can be simplified.

According to the apparatus in which the foreskin holding means provided with the holding member 45 having the U-shaped holding surface is provided together with the air needle 51, the air needle 51 and the filling nozzle 5 are provided.

The air flowing out of 1 inflates the bagged frying, after which the filling nozzle 52 is inserted. Since the air needle 51 is thinner than the filling nozzle 52, the air needle 5
There is no danger that 1 will break through the side wall of the fryer, and when the filling nozzle 52 is pierced, there is no danger that the fryer 6 will be swelled by the air injected from the air needle.

Even if the conveyed fry is not subjected to an internal separation step by air injection, the inside can be separated and expanded by injecting air from the air needle 51.

After the filling nozzle 52 is inserted into the fryer, the elevating rod 58 of the automatic filling machine is moved down to fill the fryer with filling, and then the carrier 41 of the foreskin holding means is retracted. And at a predetermined position during retreat,
The holding members 45, 45 are opened, and the fried food filled with filling is
It falls onto a chute or conveyor provided below and is carried out.

In the apparatus of the above-described embodiment, the air needle 51 and the filling nozzle 52 are inserted in a state where the side of the oil fry is set up and down, so that the air needle 51 is arranged close to and above the filling nozzle 52. Is preferred. When the tip of the air needle 51 or the filling nozzle 52 is cut off obliquely to form a needle, as shown in FIG. 12, the air needle 51 is disposed immediately above the filling nozzle 52, and the lower part of both ends is cut off obliquely. Most preferably, it is shaped.

However, as shown in FIG. 13, the tip of the air needle 51 and the filling nozzle 52 can be sufficiently cut off on the side of the tip, and the air needle 51 and the filling nozzle 52 can be sufficiently used as shown in FIG. A structure arranged inside the nozzle 52 is also a preferable structure. Further, a plate-shaped needle 5F as shown in FIG. 15 may be provided at the tip of the air needle or the filling nozzle, so that the insertion into the fried fish can be performed more reliably.
