A beverage cup filling and sealing machine is automated equipment that doses a product into cups and applies a heat-sealed film lid. The machine configuration changes according to the product’s viscosity, particle size, temperature, filling accuracy, and sealing requirements. For manufacturers using packaging machine for desserts and beverage applications, selecting the correct Yijianuo configuration can improve hygiene, reduce product waste, increase output, and support consistent retail quality across jelly, juice, and bubble tea production.
Although jelly drinks, juice, and bubble tea may use similar plastic cups, they do not behave the same during filling. A machine designed for low-viscosity juice may struggle with fruit jelly, while a standard liquid filler may damage tapioca pearls or create inconsistent portions.
The main engineering variables include:
These factors influence the metering system, pump type, valve geometry, hopper design, cup handling, sealing station, and cleaning procedure.
Cup filling and sealing developed from relatively simple manual and semi-automatic equipment used by small beverage and dessert producers. As ready-to-drink tea, fruit beverages, pudding, yogurt, and jelly snacks became more popular, manufacturers required higher productivity and better sanitation.
Modern equipment combines:
This development has made the beverage cup filling and sealing machine an important part of the ready-to-drink beverage industry. For exporters and contract packers, automated filling also supports traceability, repeatable batch performance, and more stable labor costs.
The most important differences are found in the dosing system and product-contact components. A useful starting point is the comparison below.
| Product | Main Filling Challenge | Recommended Dosing Approach | Key Machine Features |
|---|---|---|---|
| Jelly or jelly drink | High viscosity and product inclusions | Piston filler, servo piston, or wide-bore volumetric filler | Large filling nozzle, anti-drip valve, agitator, strong hopper |
| Juice | Low to medium viscosity, possible pulp and foam | Flow meter, piston filler, or timed volumetric filling | Gentle pumping, anti-foam design, pulp-compatible valve |
| Bubble tea | Liquid plus tapioca pearls or other toppings | Separate topping dosing and liquid filling | Large-particle hopper, screw or cup-style dosing, wide passages, anti-blocking controls |
Jelly products can range from smooth gelatin desserts to drinks containing fruit jelly, aloe vera, or coconut cubes. Their consistency may be semi-solid, elastic, or highly viscous.
A packaging machine for desserts and beverage products should normally include the following features for jelly:
Wider product passages
Narrow pipes and small valves can restrict jelly pieces or create blockages. The internal diameter should be selected according to the largest particle and the target filling speed.
Agitated hopper
An agitator helps prevent product separation and keeps inclusions suspended. The agitation speed must be controlled to avoid excessive shear or air incorporation.
Servo piston filling
A servo piston provides repeatable volumetric dosing for dense products. With appropriate calibration, a production line may target filling precision to ±0.01 L or a tighter value depending on cup size and product formulation. Mechanical precision claims should always be verified during site acceptance testing.
Anti-drip or cut-off nozzle
A shut-off valve reduces stringing and prevents jelly from contaminating the sealing rim.
Sanitary product-contact materials
Stainless steel components, typically specified as food-grade 304 or 316L where chemical resistance is required, support hygienic production and easier washdown.
For dessert cups such as pudding or fruit jelly, the sealing station also needs stable film tension and sufficient dwell time. A contaminated rim can cause microleaks even when the sealing temperature appears correct.
Juice is usually easier to pump than jelly, but it can introduce different problems. Clear juice, pulpy juice, nectar, and fiber-rich beverages each require different handling.
A juice-oriented beverage cup filling and sealing machine may use:
Clear juice generally supports higher filling speeds because it contains fewer solids. However, foamy products may require bottom-up filling, reduced pump speed, or a delayed nozzle retraction sequence.
For juice with pulp, the valve and pipeline must be sized to prevent fiber accumulation. Product recirculation may also be necessary to maintain consistent solids distribution. The machine should allow operators to adjust:
These settings are more important than simply selecting a machine with a high advertised cup-per-minute rating.
Bubble tea is the most mechanically demanding of the three products because it combines a liquid base with heavy or oversized inclusions such as tapioca pearls, popping boba, fruit cubes, or grass jelly.
A standard liquid filler cannot reliably dose these ingredients. A bubble tea line often requires:
A separate topping dispenser
Tapioca pearls should be portioned by a dedicated volumetric cup, rotary pocket, screw, or servo-controlled particle dosing system.
Large-bore transfer pathways
Product channels must accommodate the diameter and shape of the toppings without crushing or jamming them.
Anti-bridging hopper design
Sticky pearls can form a bridge over the outlet. Agitation or vibration helps maintain continuous feeding.
Two-stage filling
The machine may place toppings into the cup first and then fill tea or milk liquid around them. This improves portion control and reduces topping displacement.
Drainage and cleaning access
Sugar syrup and starch residue can create microbial and mechanical risks. Tool-free access and sloped surfaces help operators complete sanitation more effectively.
Flexible cup indexing
The indexing system must handle the additional weight of filled cups without slipping or damaging the cup wall.
The result is often a hybrid line: a topping dosing machine, liquid filler, cup sealer, and conveyor integrated under one PLC control platform.
The sealing process is shared across all three products, but the settings are not identical.
Most cup sealing systems include:
The sealing temperature and pressure depend on the cup and film structure, not only the beverage. Operators should validate the following:
For jelly and bubble tea, the risk of rim contamination is higher because the product may splash or carry particles. A longer settling period or a two-step filling sequence may be needed before sealing.
Quality teams can use internal test methods supported by relevant standards. For example, dimensional inspection may follow DIN ISO 2768 principles where applicable, while plastic or film mechanical properties can be evaluated using applicable ASTM methods. Seal integrity may be checked through leak, burst, peel, and visual inspection procedures defined in the company’s quality plan. The exact standard should match the packaging material and destination market.
When comparing a Yijianuo system with other suppliers, buyers should examine measurable specifications rather than general claims.
A complete factory acceptance test or site acceptance test may include:
For precision components, a supplier may specify machining or positioning accuracy to 0.01 mm. This value should be distinguished from actual filling accuracy, which depends on product viscosity, temperature, cup tolerance, and calibration.
A professional supplier should also define its technical support process. A practical purchasing requirement is a 24-hour response to service inquiries, with remote troubleshooting, spare-parts identification, and escalation procedures documented in writing.
A universal machine may fill several liquids, but it will not necessarily handle jelly pieces or tapioca pearls efficiently. Product-contact parts and dosing modules often need to be changed.
Clarification: Ask for a product trial using the actual recipe, cup, film, particle size, and target speed.
A machine running at 120 cups per minute may produce more waste if it causes underfilling, splashing, film misalignment, or frequent stoppages.
Clarification: Evaluate good cups per minute, not only theoretical speed. Overall equipment effectiveness should include availability, performance, and quality rate.
A high temperature cannot compensate for a dirty cup rim, unsuitable film, uneven pressure, or incorrect dwell time.
Clarification: Seal quality is a system result involving material compatibility, temperature, pressure, time, and surface cleanliness.
Tapioca pearls are not simply a thicker liquid. They require controlled particle dosing and anti-blocking engineering.
Clarification: Specify topping diameter, density, syrup content, target grams per cup, and whether toppings are added before or after the liquid.
Stainless steel is useful, but hygienic design also depends on weld quality, drainage, surface finish, dead-leg prevention, and cleaning access.
Clarification: Request weld inspection, surface-finish information, sanitation procedures, and a documented cleaning validation plan.
Consider a beverage producer offering three 500 ml products:
A single base platform may be possible, but the dosing modules should be different.
For mango jelly drink:
For clear apple juice:
For milk tea with tapioca pearls:
The plant may use quick-change product piping, removable nozzles, and recipe storage in the PLC. This allows operators to switch between SKUs while maintaining repeatable parameters. However, changeover validation remains necessary because different products may require different cleaning agents, temperatures, and sanitation frequencies.
Before issuing a purchase order, prepare a technical specification sheet covering the complete process.

The right machine does more than automate filling. It protects the commercial performance of the product.
A properly configured system can help reduce:
For a high-volume producer, even a 1-gram reduction in unnecessary overfill can create significant annual savings. Likewise, improved seal consistency can reduce returned products and protect brand reputation.
Yijianuo buyers should therefore evaluate equipment through total cost of ownership rather than purchase price alone. Pump wear, format-part costs, cleaning time, energy consumption, spare-parts availability, and technical service all affect the long-term return on investment.
The machine features change because jelly, juice, and bubble tea differ in viscosity, particle content, foaming behavior, filling temperature, and contamination risk. Jelly usually needs a wide-bore piston filling system and agitation. Juice benefits from flow-meter or volumetric filling with foam control. Bubble tea requires separate topping dosing, anti-bridging design, and large-particle handling.
A reliable beverage cup filling and sealing machine should be tested with the actual product and packaging materials. By combining Yijianuo engineering, accurate dosing, hygienic construction, validated sealing parameters, ASTM or DIN-based quality procedures where applicable, 0.01 mm component precision, 100% inspection, and a documented 24-hour response service process, beverage manufacturers can build a more stable and profitable production line. Explore the appropriate Yijianuo configuration before purchasing, and make the final decision based on verified product trials rather than speed claims alone.
