Description

Technical Field

[0001] This utility model relates to the field of sterilization equipment technology, specifically to a device for continuous clean transfer and sterilization of powders, mainly used in the pharmaceutical, solid beverage and other industries for rapid sterilization and drying of granular powders. Background Technology

[0002] In fields such as the production of traditional Chinese medicine preparations, the sterilization of raw medicinal powders is crucial. Traditional sterilization methods, such as moist heat sterilization and dry heat sterilization, have many drawbacks. Moist heat sterilization is time-consuming, generally requiring 30-40 minutes, and the sterilized material is prone to clumping, affecting product quality. Dry heat sterilization is also time-consuming, typically 2-4 hours, and its sterilization efficiency is low. Furthermore, these traditional methods struggle to maintain the stability of active ingredients in heat-sensitive materials, easily leading to material quality deterioration, such as discoloration and nutrient loss.

[0003] Existing powder sterilization equipment also has shortcomings in structural design and functional implementation. For example, some equipment cannot guarantee uniform heating of materials during sterilization, affecting the sterilization effect; the equipment's sealing performance is poor, easily leading to secondary contamination of the sterilized raw materials; the internal structure is not conducive to material mixing and flow, creating sterilization dead zones and making it difficult to achieve comprehensive sterilization of materials. Therefore, there is an urgent need for a sterilization device that can overcome the above shortcomings and achieve efficient and uniform sterilization while effectively protecting the quality of materials. Summary of the Invention

[0004] In order to solve the problems of the existing technology, the purpose of this utility model is to provide a device for continuous clean transfer and sterilization of powders. It aims to solve the problems of uneven sterilization, low efficiency, easy deterioration of material quality and risk of secondary contamination in existing sterilization devices, so as to achieve rapid, efficient and uniform sterilization of granular powders, while maximizing the preservation of the effective components and original quality of the material.

[0005] The technical solution of this utility model is: a device for continuous clean transfer and sterilization of powder, comprising: a sterilization chamber, a feeding device, a heating device, a first collection tank, a second collection tank, and a motor. The sterilization chamber is externally connected to a cylinder and internally contains several stirring paddles. A valve is provided between the sterilization chamber and the cylinder. The sterilization chamber, stirring paddles, and motor are connected to other components via a rotary sealing coupling.

[0006] Furthermore, the sterilization chamber is made entirely of SUS316L stainless steel.

[0007] Furthermore, the inner wall of the sterilization chamber is provided with an insulation layer and equipped with multi-angle temperature sensors, and is connected to a human-machine interface control system via a heating device.

[0008] Furthermore, the feeding device is equipped with spiral blades to feed the material in a spiral manner.

[0009] Furthermore, the rotary sealing coupling is made of SUS316L stainless steel and uses a high-temperature resistant, hygienic, food-grade silicone sealing ring.

[0010] Compared with existing technologies, the beneficial technical effects of this invention are as follows: This device mainly utilizes superheated steam as the sterilization medium, combined with a unique spiral feeding structure and precise temperature control, achieving high-temperature instantaneous sterilization of materials in just 6-8 seconds. Compared with traditional sterilization methods, this significantly improves sterilization efficiency. Due to the short sterilization time and precise temperature control, the effective components in the materials can be preserved to the maximum extent. Continuous cleaning reduces quality deterioration phenomena such as discoloration and nutrient loss, ensuring consistent product quality. Attached Figure Description

[0012] The present invention will be further described below with reference to specific embodiments.

[0013] like Figure 1 The diagram shows a device for continuous clean transfer and sterilization of powders. The device comprises: a sterilization chamber 1, a feeding device 2, a heating device 3, a first collection tank 4, a second collection tank 5, and a motor 6. The sterilization chamber 1 is externally connected to a cylinder 7 and contains several internal stirring paddles 8. A valve 9 connects the sterilization chamber 1 to the cylinder 7. The sterilization chamber 1, stirring paddles 8, and motor 6 are connected to other components via a rotary sealing coupling 10. The sterilization chamber 1 is entirely made of SUS316L stainless steel. The inner wall of the sterilization chamber 1 has an insulation layer 11 and is equipped with multi-angle temperature sensors, and is connected to a human-machine interface control system via the heating device 3. The feeding device 2 is equipped with spiral blades for spiral feeding of materials. The rotary sealing coupling 10 is made of SUS316L stainless steel and uses high-temperature resistant, hygienic, food-grade silicone sealing rings.

[0014] When the device is in operation, superheated steam is used as the sterilization medium. With the combined action of the heating device 3 and the insulation layer 11, the entire device can be precisely controlled to operate under the required sterilization temperature conditions. When powdered or granular materials are fed into the feeding device 2, its equipped spiral blades can fully stir and feed the materials in a spiral manner, allowing them to enter the sterilization chamber 1 along the flow path. Inside the sterilization chamber 1, driven by the motor 6 and the stirring paddle 8, the materials can be uniformly heated, preventing stratification. Simultaneously, by rapidly increasing the temperature, the proteins, nucleic acids, and other components of the microorganisms are destroyed, achieving rapid and efficient sterilization while minimizing the loss of effective components and nutritional flavor. This device, with the aid of temperature sensors and a human-machine interface control system, can precisely control the sterilization temperature and time, ensuring the stability and consistency of the sterilization effect and achieving the goal of continuous clean transport sterilization.
