Key Features
1. Silicone-Coated Gentle Handling System
All product-contact surfaces along the infeed conveyor, forming tube entry, and discharge path are coated with food-grade silicone that provides a coefficient of friction approximately 75% lower than bare stainless steel. This coating prevents soft products from catching, dragging, or scuffing during high-speed transfer. The silicone material is rated for continuous use with food products and withstands repeated cleaning cycles with approved sanitizing agents. Unlike PTFE-based coatings that may wear through in high-abrasion environments, the silicone layer on the JY-ZB1400S is bonded into a recessed channel within the stainless steel guide surface, providing extended service life measured in years rather than months.
2. Anti-Crush Optical Sensor Array
A multi-point optical detection system monitors product position at three critical locations: infeed exit, forming tube entry, and immediately upstream of the sealing jaws. If any sensor detects a product that is misaligned, tilted, or otherwise positioned where it would be struck by the sealing jaws, the control system triggers an immediate cycle-stop signal — faster than the mechanical movement can complete — preventing product crushing. The sensors self-calibrate at machine startup and can be tuned for different product sensitivity thresholds through the HMI. This system virtually eliminates the product waste associated with mis-fed items in soft candy packaging operations, where a single crushed product can contaminate multiple subsequent packs with sticky residue.
3. 4-Servo Independent Axis Control
The JY-ZB1400S deploys four independent servo motors managing the film feed roller, longitudinal sealing roller, transverse sealing/cutting head, and product infeed conveyor respectively. This architecture provides a significant advantage over 3-servo designs when handling soft products, because the product infeed servo can be independently tuned to match the feed characteristics of each product type. For example, jelly cups benefit from a gradual acceleration profile to prevent liquid sloshing, while marshmallows require a constant-velocity feed to avoid compression. Each axis can be programmed with unique motion profiles stored as part of the product recipe, ensuring optimal handling regardless of product type. The 4-servo system maintains positioning accuracy within ±0.3 mm across all axes at the machine's maximum speed of 1,000 packs per minute.
4. Spring-Tensioned Adaptive Guide Rails
The infeed guide rail system features spring-loaded tensioners on each lane divider, allowing the guides to flex slightly in response to product dimension variations without causing jams. This passive compliance mechanism is particularly valuable when packaging products that expand or contract with ambient temperature and humidity — a common characteristic of gelatin-based gummies, starch-molded jellies, and pectin-confectionery products. The spring tension is adjustable via set screws on each guide post, enabling operators to dial in the optimal compliance for each product type. The guide rails themselves are manufactured from 304 stainless steel with the silicone coating described above, and the entire guide assembly can be removed without tools for cleaning or product changeover.
5. Extended Film Compatibility for Soft Product Films
Soft candy products often require specialized packaging films — thinner gauge materials for transparency, cold-seal films for heat-sensitive products, or high-barrier laminates for moisture-sensitive items like marshmallows. The JY-ZB1400S is engineered to handle film gauges from 18 to 80 microns, with an adjustable film tension control system that prevents the stretching and distortion common when running thin films at high speed. The heated sealing jaw system operates across a temperature range from ambient to 200°C with ±1°C precision, accommodating the broad range of seal initiation temperatures across different film chemistries. For cold-seal applications, the heating elements can be fully disengaged, and the machine's film path is designed to maintain registration accuracy regardless of thermal state.
6. Washdown-Ready Stainless Steel Construction
Soft candy production environments often require more frequent cleaning cycles than hard candy lines due to sugar dust, starch residues, and product fragments. The JY-ZB1400S is built with a fully enclosed 304 stainless steel frame with continuous seam welds, sloped surfaces that prevent liquid pooling, and IP65-rated electrical enclosures that withstand direct low-pressure washdown. The open-frame layout ensures unrestricted access to all process areas. All bearings are sealed and lubricated for life, eliminating contamination risk from grease migration. The silicone-coated guides can be cleaned with standard food-industry sanitizers without degradation, and removable drip trays capture any product fragments or film trimmings for easy disposal.
