2. Description of the Related Art Various products related to instant puffed food in containers such as instant popcorn in containers have been developed and sold. As such a product, for example, put a cone and fats and oils, various seasonings in a frying pan-shaped aluminum foil container,
Popcorn in a container sealed with a film is sold. This type of product is intended to obtain edible popcorn by heating the container while vibrating the container horizontally in a gas range or the like to expand the cone in the container. Further, with the recent spread of microwave ovens, products of a type that obtains edible popcorn by expanding the corn in a container simply by cooking in a microwave oven have been sold. By the way, conventionally, as a method for industrially producing such a packaged food in large quantities, for example, first, a powder material such as a seasoning is mixed and dispersed in an oil or fat, and then the oil or fat in which the powder material is dispersed is mixed. A method has been adopted in which granular raw materials such as corn are mixed, and the raw materials are filled into containers in predetermined amounts. However, according to this method, there is a problem that the powdery raw material dispersed in the fat or oil sediments and separates before filling in the container, and the powdery raw material cannot be accurately filled in each container by a predetermined amount. In addition, even after commercialization, the powder raw material is locally unevenly distributed in the product, and there is a problem that the aroma and flavor of the food are likely to be non-uniform. Further, in addition to the above method, a method of first mixing the granular raw material and the fat and oil and then adding and mixing the powder raw material thereto is also adopted.
The powder raw material easily sediments and separates, and has the same problem as the above method.

BEST MODE FOR CARRYING OUT THE INVENTION
This is a form in which a container is filled with a large number of granular raw materials and an oil-based raw material in an amount equivalent to 20% by mass (hereinafter, simply referred to as “%”) or more of the granular raw materials. Specifically, for example, a containerized instant expanded food such as a containerized instant popcorn can be given as a typical example. In addition, in the case of an instant puffed food in a container, particularly, a large number of granular raw materials and 20 to 65% by mass of the granular raw materials, more preferably 30 to 50% by mass.
% Of the oil-based raw material in an amount corresponding to%. Such a packaged instant puffed food, at the time of eating, as it is or by moving the contents to another container, and cooking using a gas range or a microwave oven, etc. By puffing, a puffed food such as popcorn can be obtained.

Examples of the granular raw material that can be used in the present invention include corn, cereals such as rice, beans, beans, and snack dough formed into granules, which are used as raw materials for puffing of instant puffed foods. The corn is a blast-type corn which has been subjected to heat treatment under conditions that satisfy the temperature and time that do not cause the corn to swell for sterilization or greatly affect the water content of the corn. Are used. In this case, the corn preferably has a moisture content of 10 to 16.6% by weight.
More preferably, the content is 7 to 15.7% by weight. Further, as the fat-based material, for example, palm oil, rice oil, salad oil,
Examples include fats and oils such as heads and lards, and processed fats and oils such as shortening, margarine, butter and butter flavor. These oil-based raw materials may be used alone or in combination of two or more. When two or more kinds are used in combination, they can be mixed in advance and used.

[0008] Examples of the powdery raw material include salt,
Seasonings such as spices, sodium glutamate, sodium inosinate, cheese, sugars and the like can be given, and in addition to these, powdered flavors and pigments can also be used. The amount of the powdered raw material used is arbitrary, but it is preferable to use it in an amount corresponding to, for example, 0.1 to 10%, more preferably 1 to 8% of the granular raw material. In addition, in the case of the instant puffed food, the salt is adjusted to be in an amount corresponding to 1 to 8%, more preferably 2 to 7%, and still more preferably 3 to 5% of the granular raw material among the powder raw materials. Good to use. In the present invention, a liquid raw material may be used in addition to the powder raw material.

In the present invention, first, a granular raw material and an oil-based raw material in an amount corresponding to 0.3 to 10%, preferably 0.5 to 5%, and more preferably 0.7 to 3% of the granular raw material are used. And a powder raw material are mixed to obtain a mixture thereof. In the resulting mixture, a relatively small amount of oil-based raw material spread over the entire surface of the granular raw material acts as a binder, and the powder raw material adheres to the surface of the granular raw material. By filling the raw material, it becomes possible to accurately fill each container by a predetermined amount in a state where the powder raw material is adhered to the surface of the granular raw material. Here, when the amount of the fat or oil-based raw material is less than the above range, it becomes difficult to adhere the powder raw material to the surface of the granular raw material, and conversely, when the amount of the fat or oil exceeds the above range, the powder raw material becomes Is easy to settle and separate.
The fat and oil-based material used here can be arbitrarily selected from the above-described fat and oil-based materials, and particularly, 15 to 30.
It is preferable to use one having an SFC at 10 ° C of less than 10%, more preferably 3 to 8%. In this case, the fluidity of the fat-based material is high, so that the fat-based material is easily distributed throughout the granular material, and the powder material is easily attached to the surface of the granular material.

Here, the granular raw material, the oil-based raw material, and the powder raw material may be mixed at the same time. However, in order to suitably attach the powder raw material to the surface of the granular raw material, first, the powdered oil-based raw material is added to the oil-based raw material. It is preferable to disperse the raw materials to obtain a powder raw material-dispersed fat-based material, and then to mix the granular raw material and the powder raw material-dispersed fat-based material to obtain a mixture thereof. Here, as a method of obtaining the powder raw material-dispersed oil / fat-based raw material, an arbitrary method such as stirring and mixing of the oil / fat-based raw material and the powder raw material with a mixer can be adopted. Further, in order to uniformly disperse the powdery raw material in the fat and oil-based raw material, for example, stirring and mixing may be performed while heating to 40 to 70 ° C. Further, as a method of mixing the granular raw material and the powder raw material-dispersed fat / oil-based raw material, for example, the granular raw material and the powder raw material-dispersed fat / oil-based raw material are put into a stirring device such as a mixing pot equipped with a stirring blade and stirred. A method of mixing, or a method of adding and mixing a powdery raw material-dispersed fat or oil-based raw material to a granular raw material being stirred by a stirrer. The mixing time here is arbitrary, for example, 5-2
It can be 0 minutes. Here, mixing may be performed while heating, but it is not necessary to heat.

Next, the mixture thus obtained and the remaining oil-based raw material are filled in a container without previously mixing. Thereby, the separation of the powder raw material from the granular raw material can be prevented, and the powder raw material can be accurately filled in each container by a predetermined amount, and the container is filled with a predetermined amount of fat and oil-based raw material required for the desired food. be able to. Then, in the thus obtained food in a container, since the powdery raw material is present on the entire surface of the granular raw material, the aroma and flavor of the powdery raw material can be uniformly imparted to the whole food. As a method of filling the container without previously mixing the mixture and the remaining oil-based material, for example, a method of filling the container with the mixture and the remaining oil-based material from separate filling nozzles,
Alternatively, when the same filling nozzle is used, a method of alternately filling the same through a switching valve or the like may be used.

The order of filling the mixture with the remaining oil-based raw material in a container is such that the mixture is more than the remaining oil-based raw material in order to prevent separation of the powdery raw material from the granular raw material. It is better to fill the container first. As the remaining oil-based material to be filled in the container, any of the above-described oil-based materials can be arbitrarily selected and used.
SFC at 10 to 20% and S at 40 to 70 ° C
It is preferable to use one having an FC of less than 10%. In this case, at the time of production, for example, by heating to 40 to 70 ° C., it can be efficiently filled in a state of high fluidity, but after production, the fluidity is low at room temperature and adhesion to hands and the like is preferable. Is prevented.

The container used in the present invention may be a container made of various metals, synthetic resins, papers and the like. When this container is used for microwave cooking as it is, a microwave-permeable synthetic resin or paper is used. Containers made of etc. should be used. Further, in the case of the instant puffed food, for example, the instant puffed food in a container is manufactured by filling the instant puffed food into a small container such as a flexible small bag having a sufficient volume to accommodate the instant puffed food (small volume) before the puffing. Then, a large foldable container having a volume capable of accommodating the expanded food (large in volume) is attached to the container in a folded state, and the cooked large container is attached when cooking. The contents can be spread and transferred from the small container to the large container and cooked in a microwave oven or the like.

When the present invention is applied to a method for producing instant puffed food, it can be applied to any of a type cooked in a gas range or the like and a type cooked in a microwave oven, but is particularly effective in the latter case. It is. In other words, instant inflatable foods that are cooked in a microwave oven are different from those that cook while the container is vibrated horizontally on a gas range or the like, and do not vibrate when cooked in a microwave oven. For this reason, the powder raw material in the container is difficult to disperse throughout the granular raw material, but the present invention suitably solves this problem. Further, in a type of cooking in a microwave oven, salt is used as a part or the whole of the powdered raw material, so that during the cooking by the microwave oven, the salt which is present at a high concentration on the surface of the granular raw material is granular raw material. The power of microwave absorption at the surface of the material is increased, the heating efficiency is improved, and the granular material can be expanded efficiently.
