Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a two-layered candy in which candy is wrapped inside a candy, and this is accomplished by a newly devised extruder with a center pipe, without manual operation. The present invention relates to a manufacturing method and an apparatus used for the method.

[0002]

2. Description of the Related Art The following is a description of the process of producing a simple ordinary candy that is currently performed. First, sugar, starch syrup, starch, etc., which are raw materials for candy, are dissolved and stirred in a pot with a stirrer. Then, the mixture is boiled down by a vacuum boiler and further kneaded by a kneading machine to produce a large mass as a candy material. The mass of this large candy material is placed on a batch roll, stretched while rotating the roller, and then the thickness and temperature of the dough are adjusted to a constant value by a stamping machine, cooled by a cooling conveyor, and then cooled by an automatic packaging machine.
The products are packed individually, weighed by a weighing machine (where incompletely packaged products are removed), and finally bagged by an automatic bagging machine to complete the product. Although the above method is a generally performed step, in this method, each step until the candy material made by the kneading machine is moved to the batch roll is discontinuous and requires labor, so all the steps are required. There was a need for complete automation.

[0003] The applicants of the present invention have disclosed Japanese Patent Application Laid-Open No. 10-238.
No. 62 and improved heating temperature and / or
Alternatively, an extruder that can freely adjust the degree of vacuum was developed, and by this, the part from the pan with a stirrer to the batch roll was replaced with an extruder in the above-mentioned process, and the entire process was completely automated. That is, the above-mentioned extruder is only put the raw material from the hopper, and is melted, heated, dehydrated and kneaded in the extruder, and the candy is injected while being stretched from the injection port of the extruder. You can be guided.

[0004] The above is an ordinary method for producing candy, but it has not been possible to automate the production of candy having a two-layer structure. Conventionally, the method of manufacturing a two-layered candy has a structure of a candy to be produced in advance, as typified by the method of manufacturing a Kintaro candy, that is, a sushi roll in which candy is wrapped inside the candy. The method was to make a large chunk of stick-shaped candy by hand, stretch it by hand, and cut it. However, since this method is performed manually, it is extremely inefficient. For example, when 5,000 candy are produced per hour by the above-described automation method, even if an inspector is used from the stretching process to the packaging process, one to two persons are required. However, in the case of a two-layered candy, three to four workers are required just to make the first large candy mass (about 30 kg). In addition, to put the inner layer candy evenly in the outer layer candy, a skilled worker's hand is required, and in order to stretch or cut it, to handle the heated candy,
It was extremely dangerous and it was difficult and nearly impossible for ordinary workers to perform this task.

[0005]

SUMMARY OF THE INVENTION The inventor of the present application has proposed a large mass of a two-layered stick-shaped candy requiring a great deal of labor,
We devoted ourselves to making it automatically without using human hands, devised a method of creating an inner layer candy material with the above-mentioned extruder and injecting and filling this into the center of the outer layer candy material placed on a batch roll. However, in the estruder disclosed in JP-A-10-23862, the pressure of the outer layer candy material cannot be withdrawn,
The inner candy material flowed back into the extruder and could not be injected.

[0006]

In order to solve this problem, the inventor has developed (a) a vertical screw conveying device for feeding a fixed amount into a raw material charging hopper of an extruder so that a large amount of inner layer candy material is always constant. (B) In the hopper to make the injection pressure high enough to enable injection and filling against the pressure of the outer candy material and the narrowing pressure of the sizing roll. (C) A flexible hose capable of freely adjusting the temperature was connected to the injection port of the extruder using an electric heating tape or the like. By using the improved extruder described above, a certain amount of the inner candy material was successfully injected into the outer candy material.

[0007]

The present invention has the following configuration. That is, in the center of the outer layer candy material placed on the batch roll,
Inserting a center hose connected to the extruder with a flexible hose, stretching both candy materials into a rod shape while ejecting the inner layer candy material from the hose, and molding the double-layer candy material. Used for
As shown in FIG. 1, an extruder (4) provided with a hopper (1) provided with a pressurizing device (2) and a flexible hose (8) provided with a heating device (9) are combined into a batch roll (11). This is an apparatus for producing a two-layer candy connected in series to a fixed center pipe (12).

[0008] Among the above, the screw type is generally used as the pressurizing device (2), but it is not limited to the screw type. In addition, various pump-type devices may be used, and the pressurizing device (2) is provided in the cylinder. The screw pump for kneading / extrusion pressurization is also preferably a screw type, but is not limited thereto.
As a heating device for the flexible hose, an electrothermal heating tape is simple but should not be limited to this.

The center pipe is generally cylindrical,
The cross-sectional shape may be arbitrary. The material is copper, which is convenient for heat conduction and the like, but this can also be arbitrarily selected. The outer surface of the pipe is preferably subjected to a Teflon baking treatment to prevent sticking of the candy material for the outer layer, but not limited to this, the sticking can be prevented by adjusting the temperature of the candy. The center pipe shows good results when fixed to a batch roll,
This is also not a required format. The length of the batch roll and the length of the center pipe (including the positional relationship) determine the form of the finished product, but generally about 1: 0.8 is preferred.

The sufficiently kneaded outer layer candy material is stretched so as to be wound around a center pipe while rotating a roller on a batch roll, during which the inner layer candy material extruded from the center pipe is injected into the center of the candy. It becomes a stick-shaped book and sent to the process after the sizing roll.
