Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for coating foods and the like for the purpose of producing multilayer confectionery, sugar-coated tablets and other multilayer grains with high efficiency.

[0002]

2. Description of the Related Art Conventionally, sugar-coated tablets and the like have been manufactured by placing a core material and a coating material in a revolving pan sugar coating machine (takotsubo-shaped rotary barrel) and continuously rotating the core material for 8 to 10 hours.

[0003]

The conventional sugar coating machine is not only of a batch type, but also has a problem that it takes a long time (8 hours to 10 hours) from material input to product discharge.

Further, since the amount of processing at one time is relatively small, a large number of sugar coating machines were required for mass production.

[0005]

However, according to the present invention, by attaching a predetermined auxiliary device to the vibrating barrel, the machining time can be significantly shortened (for example, about 10 minutes), and continuous machining can be performed. The problem of was solved.

That is, the invention of the method is characterized in that after the solid core material is brought to a predetermined temperature, it is vibrated and flowed together with the coating material to adhere the coating material to the outer periphery of the solid core material. It is a coating method. Further, the solid core material is a candy or other solid confectionery, solid fertilizer, solid feed or solid medicine.

Next, the invention of the apparatus is a solid particle coating apparatus characterized in that a coating material supplying apparatus and a vibrating object stirring means are installed in an annular vibrating barrel. And a coating material supply device and a sieving device, which are solid particle coating devices.

The solid core material of the present invention can be employed in the case of producing the above-mentioned outer multilayer granulation. However, depending on the nature of the adhesive such as syrup, it is not necessary to keep the solid core material at a predetermined temperature.

[0009]

According to the present invention, since the core material and the coating material are put in the vibrating barrel and are made to flow at the same time as the vibration, it is possible to rapidly and evenly perform a large quantity batch production or continuous production.

[0010]

Example 1 A circular oscillating barrel 1 (CL-200 manufactured by Tipton Co., urethane tank) having a capacity of 200 liters shown in FIG.
Inject 1 liter (160 kg), start the vibration of the barrel, and inject 1.5 liter of syrup with a viscosity of 30 to 50 cp in sequence (inject the whole amount in 1 minute), then powder 10
After the liters (mixture of dextrin, milk powder flavor, and citric acid) were sequentially added (the whole amount was added in 1 minute), the vibration was stopped in 8 minutes.

A product having a diameter of 24 mm and an average thickness error of the coating material of ± 0.2 mm was obtained.

A hopper 2 for an adhesive material such as syrup is installed in the central portion of the annular vibrating barrel 1 (for example, a support member is extended from a stand erected on the floor to support it). At the lower part of the hopper 2, the spout pipes 3 are divided into three parts on the same circumference and installed downward. Three air cylinders 5, 5 are erected downward on the same circumference in the vicinity of the central convex portion 4 of the annular vibration barrel 1, and stirring blades 7 are provided at the ends of the rods 6, 6 of the air cylinders 5, 5. (Stirring means) are connected in series, and powder supplying devices 8, 8 for coating are installed symmetrically in diameter.

In the above embodiment, the air cylinders 5, 5
The pressurized air is supplied to and discharged from, and the stirring blade 7 is moved up and down (stroke 300 mm) via the rod 6. This elevating and lowering is performed, for example, about once per second and agitated, and the mixture of the candy, syrup and powder repeats flow and agitation and the coating proceeds rapidly, so that a desired product can be obtained in 8 to 10 minutes. . If the stirring blade 7 is horizontal, the resistance of the candy is too strong and the coating may peel off. Therefore, it is better to tilt the stirring blade 7 a little with respect to the horizontal plane (for example, 36 degrees) as shown in FIG. Good.

Examples of the powder include powder, granules, agglomerated sugars, flavors, baking soda and a mixture of citric acid.
Further, in feeds, fertilizers, medicines, etc., they are necessary components in order to form multi-layered grains having different components. For example, in fertilizers, the fast-acting material is the outer layer and the slow-acting material is the inner layer.

[0015]

[Embodiment 2] Urethane lining 11 is applied to the inner surface of the trough-shaped tank of the spiral vibrating barrel 10 in which the trough-shaped tank is swirled and fixed in a spiral shape, and the material inlet 12 is provided in the lower trough-shaped tank. A drop port 14 with a separating plate 13 is provided on the upper part, and the uppermost discharge port 15 of the vibrating barrel 10 faces the upper part of the drop port 14.

In the above embodiment, the solid core material 9 (for example, candy) to which the adhesive liquid (for example, syrup) has been previously applied is charged into the charging port 12 of the vibrating barrel 10 in which the required amount of powder 16 has been charged, and the vibration motor is used. When the solid core material 9 is started, the solid core material 9 partially contacts the powder 16 and rolls as shown by the arrow 18 in FIGS.

Since all the solid core materials 9 are subjected to substantially the same action, they are covered to substantially the same extent. However, since it moves up the inclined surface of the gutter-shaped tank, it rolls against gravity, and the powder 16 and the solid core material 9 are pressed against each other at the time of coating to reproduce a good adhesion state. be able to. Reference numeral 19 in FIG. 2 denotes a product discharge port.

[0018]

Example 3 A method for coating the surface of a metal material or a magnetic ceramic material with a synthetic resin powder (for example, polyvinyl chloride, polypropylene, 6-nylon, Teflon, etc.) using the coating apparatus of Example 2 will be described. To do. First, a predetermined amount of synthetic resin powder 16 having a particle size of about 100 to 1000 μm is charged into the vibrating barrel 10, and a metal material (for example, an iron ball for a ball valve) or a magnetic material heated from the charging port 12 to a temperature higher than the melting point of the synthetic resin is used. When the solid core material 9 such as a ceramic material (for example, a magnetic ceramic valve) is put in and the vibration motor 17 is started, the solid core material 9 is changed to the one shown in FIG.
As indicated by the arrow 18 in FIG. 4, the powder 16 partially comes into contact with the powder 16 and rolls, so that the powder 16 that comes into contact with the solid core material 9 is melted by heat to form a predetermined thickness (solid core material 9) on the surface of the solid core material 9. The thickness of the coating can be adjusted depending on the temperature of the coating). This can improve wear resistance, corrosion resistance, heat resistance, mechanical strength or commercial value.

[0019]

According to the present invention, there is an effect that a large amount of coated particles such as powder can be produced.

As compared with the conventional sugar coating machine, however, it is several tens of times more efficient, and not only batch type but also continuous production is possible, so that an integrated production line (from material supply to packaging) can be made. effective.

Further, since the apparatus of the present invention uses the vibrating barrel, there is an effect that a uniform product can be obtained by vibrating and flowing.
