Intelligent Control System – Stable & Easy Operation
Equipped with PLC and touchscreen control, the machine allows precise adjustment of filling volume, sealing temperature and production speed. Operators can quickly switch parameters for different products like yogurt, cheese, cream or sauce without complicated setup.

Stable control means fewer errors, less material waste, and more consistent product quality.

Double Head Filling System – Accurate & Clean Dosing
The dual filling nozzles ensure uniform filling for semi-liquid and viscous food products such as cream cheese, yogurt, butter, hummus and pudding.

Food-grade stainless steel contact parts guarantee hygienic production, while servo-controlled filling ensures precise portion control to reduce overfilling costs.

Heated & Mixing Hopper – Ideal for Viscous Dairy & Sauce Products
The hopper is equipped with integrated heating and mixing functions, specially designed for high-viscosity and temperature-sensitive food materials. Heating system maintains stable material fluidity, preventing solidification and ensuring smooth, accurate filling. Continuous mixing prevents ingredient separation, sedimentation and oil-water layering — guaranteeing consistent texture and quality in every cup.

Perfect for cream cheese, butter, chocolate paste, peanut butter, thick sauces and emulsified products.

Pre-Cut Lid Feeding System – Accurate & Stable Placement
This structure is designed for precise feeding and positioning of pre-cut film lids onto cups before sealing. Accurate lid placement ensures complete sealing coverage, reduces misalignment and prevents sealing defects. This improves packaging consistency and minimizes product rejection rate in dairy and food production.

The system can be customized according to cup size and lid specifications, making it suitable for yogurt, cheese, butter and sauce cup packaging.

Precise Heat Sealing – Secure & Leak-Proof Packaging
Independent temperature control ensures consistent sealing quality. The machine delivers firm, airtight sealing for pre-formed plastic cups, extending product shelf life and maintaining freshness.

Optional nitrogen flushing system available for products requiring extended shelf life.

FAQ – Rotary Cup Filling & Sealing Machine

1. What type of products is this machine suitable for?

This machine is designed for semi-liquid and viscous food products such as yogurt, cream cheese, butter, hummus, pudding, chocolate paste and thick sauces.

With the heated and mixing hopper, it is especially suitable for materials that require stable temperature control and uniform texture during filling.

2. Can it handle high-viscosity products like cream cheese or peanut butter?

Yes. The integrated heating and mixing system maintains material fluidity and prevents separation or solidification during production.

This ensures smooth filling, accurate dosing and stable sealing performance even for dense or temperature-sensitive products.

3. Is the machine food-grade and suitable for dairy production?

All product-contact parts are made of food-grade stainless steel.

The enclosed structure supports hygienic production environments required in dairy and ready-to-eat food factories.

4. How accurate is the filling volume?

The machine uses a servo-controlled filling system to ensure precise portion control.

Stable viscosity (supported by heating and mixing) further improves filling accuracy and reduces material waste.

5. Can the machine work with different cup sizes?

Yes. The rotary system and lid feeding structure can be customized according to cup diameter and height.

For multiple cup sizes, changeover solutions can be discussed based on your production needs.

6. What type of lids can it use?

The machine is designed for pre-cut aluminum foil or plastic film lids.

The precision lid feeding system ensures accurate placement before heat sealing, reducing sealing defects and improving finished product consistency.

7. Can nitrogen flushing be added for extended shelf life?

Yes. Nitrogen flushing function can be configured as an optional feature for products requiring modified atmosphere packaging.

8. What production capacity can this machine achieve?

Production speed depends on cup size, product viscosity and filling volume.

FAQ

Q1: Is this machine suitable for food products?

Yes. This machine is suitable for packaging various food paste tube and condiment, such as sauce, honey, jam, chocolate spread, and seasoning paste. It supports food-grade plastic and laminated tubes.

Q2: Can it handle sticky or viscous food materials?

Certainly. It uses a pneumatic piston pump filling system, which is ideal for viscous and sticky food materials. It ensures stable filling performance and consistent filling accuracy.

Q3: Is ultrasonic sealing safe for food packaging?

Ultrasonic sealing is widely used in food packaging. It creates strong, clean seals without direct heat contact, reducing the risk of material burning or contamination, suitable for food-grade tube packgaing.

Q4: Can the machine be customized for different tube sizes and filling volumes?

Yes. The machine supports customized filling volumes and tube sizes as your required. Tube molds and filling range can be adjusted according to your food product requirements, making it suitable for different packaging formats.

Q1: What products can this soft tube filling sealing machine be used for?

The ZS-FS007U soft tube filling sealing machine is suitable for viscous products such as mustard sauce, chili paste, ketchup, honey, cheese sauce, cosmetic creams, toothpaste, and other paste materials.

Q2: What tube materials and sizes are supported?

This machine supports plastic soft tubes and aluminum-plastic composite tubes, with tube diameters from φ16 to φ50 mm and tube lengths from 80 to 220 mm (customizable).

Q3: How accurate and efficient is the filling system?

The machine uses servo piston filling with a filling accuracy of up to ±1% and a stable production efficiency of 20–50 pieces per minute, depending on product viscosity and filling volume.

Q4: Does the machine support date or batch code printing?

Yes. The sealing and cutting structure allows letter molds to stamp production dates or batch numbers directly on the soft tubes during sealing.
