Embodiment Construction

[0035] Hereinafter, embodiments of the present invention will be described in detail based on the drawings. figure 1 It is a right side view showing the structure of a disk coating device 10 (hereinafter abbreviated as coating device 10) as an embodiment of the present invention, figure 2 is its front view, image 3 It is a plan view (top view). figure 1The device is a sleeveless type coating device using a so-called full punch type rotary drum. In the coating device 10 , to-be-processed objects such as tablets are accommodated in a rotating drum (coating pan, hereinafter simply referred to as a drum) 1 . In addition, the coating process of the object to be processed is performed by spraying the coating liquid on the object to be processed in the drum.

[0036] like Figure 1~4 As shown, in the coating device 10 , the drum 1 is provided rotatably at the center of the housing 2 . The drum 1 rotates about a substantially horizontal rotation axis O. As shown in FIG. Object...

Abstract

In a pan coating device (10) provided with a rotating drum (1) which rotates about a horizontal rotational axis line (O), an air supply chamber (13) with a larger cross-sectional area than that of an opening (7) in the front surface of the rotating drum is provided at the preceding stage of the opening (7). The air supply chamber (13) is formed inside a chamber door (11) attached to the front of a housing (2) with one end thereof communicating with the opening (7) and the other end thereof connected to an air supply duct (19) via an air supply hole (18). Air flowing into the air supply chamber (13) from the air supply duct (19) is reduced in flow velocity in the air supply chamber (13) and supplied from the opening (7) into the rotating drum (1) with the current thereof in a stable state.

Description

technical field [0001] The present invention relates to a pan-type coating device for coating tablets or powders, and more particularly to a pan-type coating device in which coating performance is improved by optimizing the introduction path of air (gas) supplied to the object to be processed . Background technique [0002] Conventionally, a coating device using a rotating drum is known as a manufacturing device for pharmaceuticals, food, and the like. For example, Patent Document 1 discloses a device that rotates a rotating drum having a polygonal cross section (here, an octagon) around a horizontal axis. Such a rotating drum is also called a coating pan, and a spraying device for supplying a coating liquid is arranged inside the drum. The powder or grain put into the rotating drum rolls along with the rotation of the drum. On the surface of the rolled powder or granule, a coating liquid such as sugar-coating liquid is sprayed from a spraying device. Along with the spra...
