Description

A drying device for traditional Chinese medicine production

technical field

The utility model belongs to the field of traditional Chinese medicine production equipment, in particular to a drying device for traditional Chinese medicine production.

Background technique

In the production process of traditional Chinese medicine, most finished medicines need to be dried to inactivate the enzymes contained in them, prevent mildew, facilitate long-term storage, and are not easy to deteriorate. At present, the commonly used drying methods include natural air drying and heating drying. Natural air drying takes a long time and is easily affected by the weather, resulting in low work efficiency and inconvenient operation. However, heating and drying often use drying equipment for drying, for example, The Chinese patent with the application number 201620916479.8 discloses a new type of traditional Chinese medicine drying equipment, which includes a drying chamber and a ventilation device. There are air outlet pipes welded in vertical multilayer arrangement on the inner wall of the drying chamber. The upper part of the drying chamber is equipped with an exhaust port and an exhaust fan, and a muffler and a temperature sensor are also installed. The bottom of the drying chamber is provided with a slag discharge port; the ventilation device An air heating chamber, an air filter and an air dehumidifier are sequentially connected to the ventilation pipe, and the air dehumidifier is connected to an intake fan, which is connected to the control system through a frequency converter to adjust the air supply volume. The hot air is exhausted outwards, resulting in low resource utilization and high energy consumption in production, and the commonly used drying equipment does not have the function of cooling Chinese medicinal materials. After drying, it is often placed in the air for cooling and then sealed. It is easy to be damp again during the cooling process, which will affect the drying effect.

A dust-removing bag is arranged inside the bag-type dust collector, and the dust-removing bag is connected to the air outlet through a pipe.

The blower is a variable frequency blower.

The damper A, damper B and damper C are all electric dampers.

The beneficial effect of the utility model is that: by setting the damper A, the damper B and the damper C on the circulation pipeline, the drying device can carry out the internal circulation of the internal hot air and the external circulation of the external air, and the hot air can be used in the drying process. The internal circulation reduces heat energy consumption and saves electricity. After the drying of Chinese medicinal materials, the external cold air can be dried and blown into the drying chamber to cool down the medicinal materials, reduce the production cycle and increase the output.

Detailed ways

The technical solution of the utility model is further described below, but the scope of protection is not limited to the description.

As shown in Figure 1, a kind of drying device that is used for the production of traditional Chinese medicine is characterized in that: comprise drying chamber 1, drying storehouse 2, heater 4, dehumidifier 5, bag filter 7, damper A8, blower 16, all The drying chamber 2 is a cylindrical cavity, and the drying chamber 2 is installed in the drying chamber 1. The lower part of the drying chamber 1 is provided with an air inlet 3, and the upper part of the drying chamber 1 is provided with an air outlet 6. The air outlet 6 passes through a pipeline. Connect the bag filter 7, damper A8, blower 16, dehumidifier 5, heater 4, air inlet 3 in turn, the pipeline between the bag filter 7 and the damper A8 is provided with an exhaust pipe 9, and the exhaust pipe 9 is provided with damper B10, and the pipeline between described damper A8 and air blower 16 is provided with air inlet pipe 11, and air inlet pipe 11 is provided with damper C12, when using this drying device, first the Chinese medicinal material that needs drying Put it into the drying chamber 2 and close the door. The drying chamber 2 rotates in the drying chamber 1 under the drive of the motor. The traditional Chinese medicine inside the drying chamber 2 is constantly turned to improve the drying effect. , due to the high moisture content in Chinese herbal medicines, in order to reduce the load on the dehumidifier, it is necessary to close the damper A8, and open the damper B10 and damper C12, at this time, the external air flows into the blower 16 through the air intake pipe, and is blown in after being dried and heated. In the drying chamber 1, the moisture in the medicinal materials is taken away, and after dust removal, it is discharged into the atmosphere from the exhaust pipe 9. In the middle and late stages of drying, the moisture in the medicinal materials is low at this time. In order to reduce the consumption of heat energy, the air door needs to be opened A8, and close the damper B10 and damper C12, at this time, the air in the drying device flows out from the air outlet 6 and then passes through the bag filter 7, the damper A8, the blower 16, the dehumidifier 5, the heater 4, and finally passes through the air inlet 3 Enter the drying chamber 1 again, thereby reducing the discharge of hot air and improving the utilization rate of heat energy. After the medicinal materials are dried, the temperature needs to be cooled quickly to improve production efficiency. It is necessary to close the damper A8 and open the damper B10 and damper C12 , and turn off the heater 4, the external air enters the drying chamber 1 after being dehumidified, takes away the heat in the drying chamber 1, rapidly cools down, and avoids the phenomenon of dampness during natural cooling, during the rotation of the drying chamber 2 , Chinese medicines will collide with each other to produce powder. In order to avoid dust from affecting the blower 16, dehumidifier 5, and heater 4, a bag filter 7 is set outside the air outlet 6 to achieve the purpose of collecting dust.

The air outlet 6 is provided with a temperature sensor 13 and a humidity sensor 14, which are used to detect the air temperature and humidity at the air outlet 6. If the rate of change of the air humidity tends to be gentle during the drying process, the air volume of the blower 16 can be reduced. , has reached the purpose of energy saving.

The air inlet 3 is in the shape of a trumpet, and after the hot air enters the drying chamber 1, it is evenly diffused through the air inlet 3 in the shape of a trumpet, so as to improve the drying effect.

The drying chamber 2 is provided with a plurality of ventilation holes, so that hot air can enter the drying chamber 2

, the medicinal materials are dried.

The bag filter 7 is provided with a dust-removing bag 15, which is connected to the air outlet 6 through a pipe, and the air containing dust enters the dust-removing bag 15 after coming out of the air outlet 6, and the dust is left in the dust-removing bag through the filter of the bag. In the cloth bag 15, avoid dust to affect blower 16, dehumidifier 5, heater 4.

The blower 16 is a variable frequency blower, which is convenient to adjust the output power according to the air temperature and humidity in the drying chamber 1 .

The damper A8, the damper B10 and the damper C12 are all electric dampers, which is convenient to realize automatic control of the switch of each damper and improve work efficiency.
