Working Principle
The gummy twin-screw pump belongs to a positive displacement pump, which mainly relies on two meshing but non-touching screws to work. The details are as follows:
Formation of Sealed Chambers: Inside the pump body, the driving screw and the driven screw mesh with each other. As the screws rotate, a series of continuous sealed chambers are formed between the screws and between the screws and the pump body.
Suction of Gummy Materials: At the feeding port, when the screws rotate, the volume of the sealed chambers gradually increases, forming a low-pressure area. Under the action of atmospheric pressure or other pressure sources, the gummy materials are sucked into these sealed chambers.
Conveyance of Gummy Materials: With the continuous rotation of the screws, the sucked gummy materials are continuously pushed along the axial direction of the screws by the sealed chambers, just like a nut moving on a screw.
Discharge of Gummy Materials: At the discharging port end, the volume of the sealed chambers gradually decreases, and the materials are squeezed, resulting in an increase in pressure. Thus, the gummy materials are discharged from the discharging port, realizing the conveyance of the gummy materials.
Features
Precise Measurement: The meshing and rotational movement of the twin screws can precisely control the conveying amount of the materials, ensuring that the amount of gummy materials conveyed each time is relatively accurate, which helps to guarantee the consistency and quality stability of the products.
Wide Application Range: It can be applied to gummy materials with different viscosities and shapes. Whether it is high-viscosity gel-like gummies or gummies with particles such as fruit pieces, it can convey them well.
Good Hygiene: It is usually made of food-grade stainless steel and other materials, with a smooth surface and no hygienic dead corners. It is easy to clean and disinfect, complies with the hygienic standards of food production, and can effectively prevent the gummy materials from being contaminated.
Smooth Operation: The transmission mode of the twin screws makes the materials move smoothly during the conveying process, without generating strong impacts and vibrations. This reduces the possibility of deformation and damage of the gummies during the conveying process, which is beneficial to maintaining the integrity of the appearance and shape of the gummies.
Strong Self-priming Ability: It has good self-priming performance and can quickly suck in gummy materials without the need for additional self-priming devices, improving work efficiency.
Low Shear Force: When conveying gummy materials, the shear force between the screws and the materials is small, which will not excessively damage the structure and texture of the gummies, and can maintain the original quality of the gummies.
Application Fields
Food Processing Industry: It is mainly used in the production of various types of gummies, such as the conveying of ingredients for fruit-flavored gummies, fruit juice gummies, functional gummies, etc., and the transfer of materials after mixing and stirring.
Pharmaceutical Industry: In the pharmaceutical field, it can be used for the conveying of materials of some gel-like pharmaceuticals and health products, such as the transfer of materials in the production of pharmaceuticals or health products like vitamin gummies and probiotic gummies.
Selection Key Points
Flow Rate and Pressure: Determine the required flow rate and pressure range according to the scale and process requirements of gummy production, and select a pump model that can meet the conveying requirements.
Material Characteristics: Fully consider the characteristics of the gummy materials, such as viscosity, temperature, fluidity, and whether there are particles, etc., and select appropriate screw materials, structures, and pump types to ensure the conveying effect.
Hygienic Standards: Ensure that the selected gummy twin-screw pump complies with relevant food hygiene standards, such as EHEDG (European Hygienic Engineering & Design Group) and FDA (Food and Drug Administration) standards. The equipment should be easy to clean and disinfect to avoid material residues and the breeding of bacteria.
Drive Mode: Select an appropriate drive mode, such as electric drive, pneumatic drive, etc., according to the usage environment and requirements. The electric drive has the advantages of strong power and precise control, while the pneumatic drive has the characteristics of explosion-proof and safety.
Brand and Quality: Select products from well-known brands with reliable quality, which can guarantee the performance and service life of the pump. At the same time, better after-sales service can also be obtained.
