The following detailed description of the preferred embodiments of the invention, taken in conjunction with the accompanying drawings, which are incorporated in and constitute a part of this application, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention and not to limit the scope of the invention.

Referring to fig. 1, the present invention provides a capsule drying device. The capsule drying device can be applied to capsule production and is used for drying the produced capsules.

It should be noted that the mobile device of the present invention is not limited to the capsule production, and can also be applied to other production activities requiring drying. In the present invention, only the production of the capsule is taken as an example for illustration, and the principle in other application scenarios is substantially the same as the principle applied to the capsule production, which is not repeated herein.

This capsule drying device includes drying chamber 1, transmission device 2, air dryer 3 and gas-supply pipe 4, and drying chamber 1 has dry chamber 11 and the feed inlet and the discharge gate that communicate dry chamber 11, and transmission device 2 runs through dry chamber 11 through feed inlet and discharge gate and arranges for the transportation capsule passes dry chamber 11, is passing dry chamber 11 in-process drying capsule. The air outlet end of the air dryer 3 is communicated with the drying cavity 11 through an air conveying pipe 4 and used for conveying dried air into the drying cavity 11, and the moisture evaporation on the surface of the capsule is accelerated by reducing the humidity of the air around the capsule, so that the capsule is dried. Compared with the traditional heating and drying method, the device can dry at normal temperature, and avoid bad temperature control and high-temperature damage to the capsule.

There are two ways to accelerate the evaporation of the liquid water, one is heating and the other is to reduce the humidity of the surrounding air, so that maintaining a low humidity environment inside the drying chamber 11 facilitates the drying of the capsules. Therefore, in some embodiments, the drying chamber 1 is formed with an air inlet channel 12, and the air inlet channel 12 has an air inlet communicated with the air pipe 4 and a plurality of air inlet outlets communicated with the drying chamber 11 and uniformly distributed along the conveying direction of the conveying device 2. The air dried by the air dryer 3 enters the air inlet channel 12 through the air pipe 4 and then uniformly enters the drying cavity 11 through the air inlet outlet, so that the dry air in the drying cavity 11 is uniformly distributed.

Similarly, the drying chamber 1 may also be formed with an outlet channel 13, and the outlet channel 13 has a plurality of outlet inlets communicating with the drying chamber 11 and uniformly distributed along the conveying direction of the conveying device 2, and an outlet communicating with the outer surface of the drying chamber 1. After the capsule is dried, the water is changed into water vapor to enter the air in the drying cavity 11, so that the humidity in the drying cavity 11 is increased, and the drying capacity is reduced. Along with the air-supply pipe 4 is constantly let in dry air to drying chamber 11, pass through outlet channel 13 with the higher air of original humidity in drying chamber 11 and discharge, maintain the inside dry environment of drying chamber 11, keep drying capacity.

In the preferred embodiment, a gas return pipe 5 is further included for communicating the outlet with the inlet of the air dryer 3, and the gas return pipe 5 is used for guiding the air discharged from the outlet back into the air dryer 3 for drying and using again. Since the water content of the capsule is low and the amount of water vapor generated after drying is not large, the humidity of the air discharged from the air outlet is still generally lower than the humidity of the outside air, i.e. the air is still drier compared to the outside air, and therefore the burden on the air drier 3 is smaller when the drier air is prepared by using the drier air than when the outside humid air is used.

In some embodiments, the transmission device 2 includes a driving wheel 21, a driven wheel 22, and a conveying belt 23 sleeved on the driving wheel 21 and the driven wheel 22 and tensioned. The driving wheel 21 can rotate autonomously, power is provided, and the driving wheel 21 is driven to rotate by a built-in or external motor. The driving wheel 21 and the driven wheel 22 are arranged outside the drying cavity 11, and the conveying belt 23 penetrates through the drying cavity 11 through a feeding hole and a discharging hole. The conveyer belt 23 is provided with a plurality of air holes, and the drying air input through the air pipe 4 can pass through the air holes, so that each surface of the capsule can be fully contacted with the drying air and is fully dried.

In a preferred embodiment, the conveyor belt 23 comprises a carrying portion for carrying the capsules, i.e. the upper half of the conveyor belt 23 shown in the figures, and an empty portion. The empty part does not carry the capsule, i.e. the lower half of the conveyor belt 23 shown in the figure. The no-load part is arranged outside the drying cavity 11, and the bearing part penetrates through the drying cavity through the feeding hole and the discharging hole. With this arrangement, only a length of the conveyor belt 23 passes through the inlet and outlet, and the size of the inlet and outlet can be reduced, as long as the carrying section and the capsules thereon are allowed to pass through. By reducing the size of the inlet and outlet ports it is recommended to reduce the exchange of air between the interior and the exterior taking place at the inlet and outlet ports and to reduce the entry of external moist air into the drying chamber 11.

The air dryer 3 has an air inlet end and an air outlet end, and can suck air from the air inlet end, remove a part of moisture in the air, and discharge the air from the air outlet end after the air becomes dry air. In this application, dry air is not narrowly defined as air having zero humidity, but rather air having a lower humidity content than the ambient air in which the device is located. The air dryer 3 does not need to reduce the humidity of the air for drying the capsule to zero, and can obtain a faster drying effect than ordinary air by reducing the humidity.

In a preferred embodiment, the capsule drying device further comprises a feeding device 6, wherein the feeding device 6 comprises a feeding hopper 61 and a feeding pipe 62, the upper end of the feeding pipe 62 is communicated with the feeding hopper 61, and the lower end of the feeding pipe 62 points to the bearing part. Capsules are added to an upper hopper 61 and can be transported to the conveyor belt 23 through a feed pipe 62.

The surface of the feeding wheel 63 is provided with a plurality of bulges, and the feeding hopper 61 is made of flexible materials such as cloth and has flexibility. When the feed wheel 63 rotates, the projections intermittently abut against the upper hopper 61 and press the upper hopper 61 to deform it. So that vibrations are created at the junction of the feeding hopper 61 and the feeding pipe 62 to eliminate the clogging of the capsules.

In a preferred embodiment, a heater 7 may be further disposed in the air pipe 4 to heat the dried air, so as to improve the drying efficiency. It will be readily appreciated that, in order to avoid damage to the capsule, the power of the heater 7 should be effectively limited so that the heat it generates will heat the air to a temperature well below the damage temperature of the capsule, i.e. on a safety basis.

In the preferred embodiment, an air separation device 8 is also provided, the air separation device 8 comprising an air blower 81, a good product collecting box 82 and a waste product collecting box 83 arranged in sequence at the end of the conveyor 2. The capsules may be filled insufficiently or even empty, so that the capsules are lighter and fall farther into the waste collection box 83 under the blowing of the blower 81. And the capsule quality of normal powder charge is great, can fall more closely under the blowing of air-blower 81, falls in the non-defective products collection box 82 to realize the screening function.

When the device is used, the air dryer 3 can be started to operate for a period of time, so that the drying cavity 11, the air conveying pipe 4 and the air conveying return pipe 5 are filled with dry air, then the conveying device 2 and the heater 7 are started, and capsules are added into the feeding hopper 61 for drying.
