Equipment Details
Vertical Cup Holder and cup loading system
•The extended cup storage compartment allows for one-time cup filling and can operate for at least 20 minutes.
•The cup guiding device enables easy addition of cups by hand, with a user-friendly operation.
•The vacuum suction cup assists in the cup dropping process, making it more stable and accurate.
Cup Detection and Cleaning
•Detect whether there is a cup or not through photoelectricity. No cup means no filling.
•The ion wind sweeps the empty cup, effectively preventing static electricity from adhering, and at the same time, it uses vacuum to remove dust and other foreign substances.
•Strong ultraviolet irradiation further enhances the cleanliness level.
Filling and Cleaning System > Fully sanitary structure design (Food / Pharmaceutical Grade) ;
•The liquid-contact parts of the entire machine are made of SUS304/SUS316L stainless steel.
•The inner surface is polished with a mirror finish, reducing the risk of residue and wall attachment.
•Arc-shaped transition design to avoid accumulation of materials in dead corners
•Quick-install clamp structure, easy to assemble and disassemble, reducing pollution risks.
•The filling error can be controlled within ±1% (depending on the properties of the material)
• Anti-drip and anti-leakage structure design, reducing wire drawing and splashing
> Spray ball CIP cleaning system;
•Internal circulation cleaning (Full CIP Loop) ;The cleaning solution circulates within the system, covering storage tanks, pipelines, distributors, and filling heads. It is suitable for high-standard food products or continuous production lines.
•Quick pulse cleaning (Pulse Cleaning); By using pulse spraying to enhance the flushing force, it effectively removes sticky residues and significantly shortens the cleaning time.
> Fluid stable conveying system;
•Sanitary hose connection.
•Streamlined flow path, reduction of pressure fluctuations.
•Pressure equalization distribution structure, ensuring consistency for multiple heads.
Lid Placing and position system Vertical Lids Storage
•made of polished stainless steel, can ensure that the lids does not deform while facilitating smooth extraction without any jamming.
•> Placing system
•The vacuum flexible loading and unloading mechanism, combined with the precise repetitive positioning design of the mechanical structure, enables efficient visual positioning.
> Lids detecting system
•Photoelectric detection, automatic shutdown upon no lid detection, and manual lid replenishment by workers is possible.
Heat Sealing System
•Sealing pads able to seal every type of heat-sealing foil. Easy to change and clean
•Sealing temperature be controlled by thermocouple
•Sealing pads every area temperature is same
•because of our designed elec-heating technology, in this case, sealing effect been improved.
•All sealing parameters are adjustable (time-pressure-temperature) •Fast removal system for easy cleaning, maintenance and changeover
Cup Output & Conveying System
•Catching the cups.
•Rotating the arm and place the capsules on an exterior conveyor
•Stainless Steel frame conveyor with plastic belt
Date coding and inspection
•Ultraviolet laser marking machine; Cold processing principle: No scorching, no deformation The markings are clearer and more detailed. More friendly to thin-walled PP; No consumables, long-term costs are controllable; More environmentally friendly, with dust recovery included
•Visual inspection
Box Packing
•Organize the materials in an orderly manner
•Robot automatic box-filling
•Spray glue and close the box
