Description

Technical Field

[0001] The invention relates to the field of agricultural product processing, and in particular to an air intake device suitable for a vacuum pulsation dryer. Background Art

[0002] Vacuum pulse drying is a drying technology that combines vacuum drying and pulsating pressure to achieve rapid and efficient drying of materials. It produces pulse pressure changes by periodically adjusting the vacuum degree, accelerating the migration and evaporation of moisture.

[0003] A vacuum pulsation dryer requires an exhaust system and an air intake system, which work together to periodically regulate the vacuum level within the drying chamber. Untreated air entering the drying chamber can affect the temperature and moisture content of the drying chamber. Furthermore, airborne pollutants and fine particulate matter can also contaminate the drying chamber. To ensure that the air entering the drying chamber is pure and at a temperature that matches the drying chamber's ambient temperature, thereby avoiding adverse effects on material drying quality, it is crucial to design a device to pre-treat the air entering the dryer. Summary of the Invention

[0004] The purpose of the present invention is to propose an air intake device that can purify and heat the air entering the vacuum pulsation dryer to solve the problems existing in the above-mentioned prior art. It can ensure that the gas entering the drying chamber is pure and the temperature matches the environment in the drying chamber, thereby avoiding adverse effects on the drying quality of the material.

[0005] To achieve the above object, the present invention provides the following solutions:

[0006] The present invention provides an air intake device suitable for a vacuum pulsation dryer, comprising an air purification system, a wind power transmission system, and a heating system. The air purification system comprises an ultraviolet lamp, a fiber filter layer, and a carbon filter layer, which are sequentially nested. The wind power transmission system comprises a fan, a motor, and a bracket. The heating system provides heat from an electric heating coil.

[0007] After the above-mentioned air intake device is started, air enters the device from the ventilation shell. Under the attraction of the wind transmission system, it passes through the carbon filter layer and the fiber filter layer in turn for interception, adsorption and filtration, and then is irradiated by ultraviolet light to disinfect and sterilize the air to complete the purification process.

[0008] The air transmission power of the above-mentioned air intake device comes from the wind transmission system. On the one hand, the fan attracts air outside the device into the device to complete the purification process, and on the other hand, it pushes the air into the heating device for heating treatment.

[0009] The air intake device is connected to the vacuum pulsation dryer through a solenoid valve, so as to control and adjust the amount of air entering the vacuum pulsation dryer. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The purpose of the present invention is to provide an air intake device suitable for a vacuum pulsation dryer to solve the problems of the prior art. The air entering the vacuum pulsation dryer is purified and heated to ensure that the gas entering the drying chamber is pure and the temperature matches the environment in the drying chamber, thereby avoiding adverse effects on the drying quality of the material.

[0018] In this embodiment, a ventilation shell is provided on the outside of the air purification system, and the ventilation shell is used to allow air to enter the device.

[0019] In this embodiment, the carbon filter layer is made of activated carbon, which has a highly developed pore structure. When the air entering the device passes through the carbon filter layer, the particulate matter in the air will be adsorbed by the microscopic pore structure of the activated carbon, achieving a purification effect.

[0020] In this embodiment, the air is heated by an electric heating coil, which has a fast heating speed, good effect, and is easy to control. The required heating temperature of the air can be adjusted according to the temperature in the drying chamber of the vacuum pulsation dryer.

[0021] When in use, the device draws air into the interior through the action of the motor 207 and the fan 205. The air passes through the ventilation shell 204, the carbon filter layer 203, and the fiber filter layer 202 to complete the filtration process, and then is sterilized and disinfected by the ultraviolet lamp 201 to complete the purification function. The motor 207 and the fan 205 then transport the purified air to the heating system, and the electric heating coil 208 heats the air to complete the heating process. The completion of the above process completes the pretreatment of the air entering the vacuum pulsation dryer. Finally, the treated air passes through the pipeline and enters the vacuum pulsation dryer under the control of the solenoid valve 1.

[0022] The above only represents a preferred embodiment of the present invention. It should be emphasized that for ordinary technicians in this technical field, a series of improvements and optimizations can be made without departing from the principles of the present invention. These improvements and optimizations should also be regarded as falling within the scope of protection of the present invention.
