Description

A hot air circulation drying system

technical field

The utility model relates to a hot air circulation drying system, which belongs to the technical field of medicinal material drying equipment.

Background technique

The hot air circulation drying system is an important drying equipment for pharmaceutical production enterprises. The hot air circulation drying system adopts the fan circulating air supply method. The hot air is sent out, and then goes through the air duct to the inner room of the oven, and the used air is sucked into the air duct to become the air source for recirculation. At present, the medicine tray inside the oven of the existing hot air circulation drying system is a fixed structure, and its heating method is static heating, which has disadvantages such as uneven heating of medicines, slow drying speed and low efficiency; in addition, the existing oven Feeding and discharging are manual operations, which are time-consuming and labor-intensive. Third, the existing drying system does not adopt the protection of impurity removal and sterilization. When the hot air circulation drying system works, a large amount of gas containing impurities will be discharged, which is easy to cause pollution to the medicine. .

Utility model content

In order to overcome the defects existing in the prior art, the purpose of this utility model is to provide a hot air circulation drying system with a rotary structure in the medicine tray inside the oven. The hot air circulation drying system is simple in structure and reasonable in design, and adopts dynamic heating. In this way, the heating is uniform, the drying speed is fast, and the efficiency is high.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a hot air circulation drying system, including a box body, the box body is provided with an air outlet pipe and an air inlet pipe, and the air outlet pipe is sequentially connected with a first fan, a second fan and A heating and pressurizing device, the heating and pressurizing device is connected with the box body through the air inlet pipe; a rotary medicine holding tray driven by a motor is arranged inside the box body, and the rotary medicine holding tray is connected with the motor through a rotating shaft; the top of the box body is provided with a The infrared disinfection baking lamp is provided with a heating baking lamp at the bottom and side walls of the box body, and a door body is hinged on the side wall of the box body.

The rotary medicine holding tray is provided with a feeding pipe and a discharging pipe which are communicated with the feeding and discharging fans.

The air intake pipe is provided with a filter screen.

A cover is provided on the upper surface of the rotary medicine tray.

There are at least two infrared sterilizing and baking lamps arranged on the top of the box body, at least one heating and baking lamp arranged at the bottom of the box body, and at least one heating and baking lamp arranged on the side wall of the box body.

Compared with the prior art, the utility model has the following advantages: (1) the structure is simple and the design is reasonable, the medicine holding tray is a rotary structure, that is, a dynamic heating method is adopted, and the medicine holding tray rotates continuously during heating, effectively It prevents the shortage of uneven drying caused by uneven heating inside the box, and has the advantages of uniform heating, fast drying speed and high efficiency. (2) The rotary medicine tray is provided with a feeding pipe and a discharging pipe which are connected with the feeding and discharging fans. The feeding and discharging are all operated by fans instead of manual operation. The efficiency of feeding and discharging is improved. (3) A filter screen is arranged on the air inlet pipe, a cover is arranged on the upper surface of the rotary medicine tray, and an infrared disinfection baking lamp is arranged on the top of the box to effectively prevent impurities and bacteria from polluting the medicine. (4) The bottom and side walls of the box are provided with heating and baking lamps, which increases the drying method. When the hot air system cannot work normally, it can be dried in an emergency. In addition, when the drying time is tight, heating and baking lamps can be used. The hot air heats and bakes at the same time, which greatly improves the drying efficiency.
