Description

Technical Field

[0001] This utility model relates to the technical field of multi-layer chamber continuous coating equipment, and more particularly to a multi-layer chamber continuous coating equipment. Background Technology

[0002] In industries such as feed, pharmaceuticals, and food, coating technology is widely used to improve product stability, extend shelf life, mask unpleasant odors or tastes, and control release. Traditional multi-layer chamber continuous coating equipment typically suffers from low drying efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a multi-layer chamber continuous coating device that is simple to operate and improves drying efficiency.

[0004] This utility model is achieved through the following measures: A multi-chamber continuous coating device is characterized by comprising a base, on which a processing cylinder is disposed, and four chambers are arranged sequentially from top to bottom through corresponding partition plates: a mixing chamber, a coating chamber, a drying chamber, and a feeding chamber. A rotating shaft is provided in the middle of the upper end face of the processing cylinder. After the rotating shaft extends into the mixing chamber, several sets of stirring rods are arranged around it. A motor is provided on the upper end face of the processing cylinder. The upper end of the rotating shaft is located on the output shaft of the motor. The motor drives the rotating shaft to rotate, thereby driving the stirring plate to perform a stirring operation. The upper end face of the processing cylinder is provided with a through solid feed port, a liquid feed port and a powder feed port for adding raw materials and coating materials in different forms; A hot air blower, which works in conjunction with the drying chamber, is installed on the outer surface of the processing cylinder for drying materials.

[0005] The specific features of this utility model also include: The processing cylinder is provided with three sets of slots that extend into the interior and cooperate with the four chambers. The partition plate is slidably disposed in the slot, and the partition plate forms the bottom plate of the corresponding chamber. When the partition plate is inserted, it forms the bottom plate, and when it is pulled out, the material can fall into the chamber below. A handle is provided at the outer end of the isolation plate away from the slot, and a limit groove is provided on the lower side of the isolation plate; Three sets of auxiliary plates are provided on the outer side of the processing cylinder. The auxiliary plates are located on the lower side of the corresponding slots. The auxiliary plates are provided with limiting blocks that slide with the limiting grooves. When the isolation plate is slid outward, the cooperation between the limiting blocks and the limiting grooves can prevent the isolation plate from detaching from the processing cylinder.

[0006] Three sets of retaining rings are provided on the inner wall of the processing cylinder. The retaining rings are set on the upper side of the corresponding slots. The upper side of the retaining ring is set as an inclined surface, and the lower side of the retaining ring slides against the upper side of the partition plate. When the partition plate is slid outward and the material falls, the retaining rings can effectively prevent the material from splashing out of the slot.

[0007] The rotating shaft extends downwards, passing through the mixing chamber and the coating chamber in sequence until it reaches the drying chamber. Several sets of stirring rods 2 are arranged around the rotating shaft in the coating chamber, and several sets of stirring rods 3 are arranged around the rotating shaft in the drying chamber. The stirring rods 2 enable the material to be coated quickly and evenly, and the stirring rods 3 enable the material to dry quickly.

[0008] The isolation plate is provided with a notch or groove that mates with the rotating shaft. Three sets of covering rods extending towards the center of the cylinder are provided on the inner wall of the processing cylinder. The lower side of the covering rod is attached to the upper side of the corresponding isolation plate and covers the corresponding notch or groove. The inner end face of the notch or groove is an arc-shaped surface that mates with the rotating shaft. The upper side of the covering rod is set as an arc-shaped surface to prevent material from accumulating on the covering rod. The free end of the covering rod is set as an arc-shaped groove that mates with the rotating shaft. After the isolation plate is inserted, the covering rod is attached to and covers the notch or groove, thereby forming a sealed bottom plate, preventing material from falling.

[0009] The inner wall of the coating chamber is provided with a pair of annular grooves, arranged vertically. Each of the annular grooves contains an annular tube. Each of the two annular tubes is provided with several sets of nozzles that are inclined downwards and face the center of the processing cylinder. A lower pipe is provided on the lower annular tube, which extends out of the processing cylinder and connects to an inner storage tank containing the inner coating liquid. An upper pipe is provided on the upper annular tube, which extends out of the processing cylinder and connects to an outer storage tank containing the outer coating liquid. Both the upper and lower pipes are equipped with corresponding pumps to spray the coating liquid into the coating chamber through the nozzles. In the feed, pharmaceutical and food industries, multi-layer coating technology achieves the protection, controlled release or functional enhancement of core substances through layered design. The inner coating fluid (basic coating fluid) mainly provides basic fixation, stability and compatibility support, such as phosphate buffer used in medicine, while the outer coating fluid imparts special functions (such as moisture protection, sustained release, targeted release, etc.), such as enteric coating materials, bovine serum albumin (BSA) solution, skim milk solution, etc. This embodiment shows the structure for achieving two-layer coating.

[0010] The drying chamber is equipped with a through air inlet and two air outlets. A pipe is connected to the hot air blower at the air inlet, and the hot air generated by the hot air blower enters the drying chamber through the pipe. The air outlet is covered with a protective cover fixed to the outer surface of the processing cylinder. The protective cover is provided with an inclined channel communicating with the air outlet. A fence is provided at the outlet of the inclined channel to prevent foreign objects from entering. Both the air inlet and the air outlet in the drying chamber are equipped with annular filters that cooperate with the processing cylinder to prevent materials from entering the air inlet or the air outlet.

[0011] The material discharge chamber has a discharge port on its lower side, and the bottom plate of the material discharge chamber is an inclined plate that slopes toward the discharge port to facilitate the flow of materials.

[0012] A door for opening and closing is provided at the discharge port.

[0013] Several sets of support rods are provided between the base and the processing cylinder to stably support the processing cylinder.

[0014] The beneficial effects of this utility model are as follows: the equipment has a simple structure and is easy to operate. By designing multiple chambers, the operating efficiency is improved. By equipping the drying chamber with a hot air blower, the drying efficiency is improved. Attached Figure Description
