Embodiment 1

[0043] Example 1: A pellet coating equipment, such as figure 1 As shown, it includes a hollow outer shell 1, a support frame 2 and a pot body 3 arranged in the outer shell 1, a spraying mechanism 4 for spraying the pellets and a drying mechanism 5 for drying the pellets (see figure 2 ). An opening and closing door 11 is opened on the vertical surface of the outer shell 1 facing the pot body 3 to facilitate sealing and observing the coating state.

[0044] Such as figure 2 As shown, the support frame 2 is placed in the outer shell 1, and the pot body 3 is rotatably connected to the support frame 2 and can rotate on the support frame 2. The pot body 3 is in the shape of a water chestnut, from the upper end to the lower end, the pot body 3 is inclined to the side close to the opening and closing door 11.

[0045] The spraying mechanism 4 includes an atomizing head 41 arranged in the pot 3, a drug delivery tube 42 communicating with the atomizing head 41, and a mounting frame 6 for i...

Embodiment 2

[0050] Example 2: A pellet coating equipment, which differs from Example 1 in that: image 3 As shown, a second drying port 542 is opened on the end surface of the drying tube 54 away from the connecting tube 53.

Embodiment 3

[0051] Example 3: A pellet coating equipment, which differs from Example 2 in that: Figure 4 As shown, the angle between the second drying opening 542 and the horizontal plane is 60°.

Abstract

The invention discloses pellet coating equipment and a pellet coating process. The coating equipment comprises a supporting frame, a pot body, a medicine spraying mechanism and a drying mechanism, thedrying mechanism comprises an air blower and a ventilating pipe, the ventilating pipe comprises a communicating pipe communicating with the air blower and a drying pipe used for drying a pellet, oneend of the communicating pipe extends into the pellet, the drying pipe is located in the pellet, and the drying pipe is provided with a first drying port for blowing the pellet out of a pellet pile. The equipment has the advantage that the drying effect and the medicine feeding uniformity are improved.

Description

Technical field [0001] The invention relates to the field of pellet coating technology, more specifically, it relates to a pellet coating equipment and a coating process thereof. Background technique [0002] Coating pan is a commonly used equipment in pharmacy. It is mainly used for pelletizing drugs and slow-release agents. Among them, the water chestnut-type coating machine is the most commonly used. The pan of the coating machine can be rotated. When the pellets are poured into the pan, the pan rotates and the pellets move in the pan, spray the coating liquid, and are dried to realize the adhesion of the drug and the sustained-release agent. [0003] The authorized announcement number is CN206372292U, and the publication date is August 4, 2017. The Chinese utility model patent discloses a coating pan drying facility and equipment, including a pan body, a support frame and a blower. The top of the support frame is equipped with a pan body A blower is provided on the side of the...
