Preserved Fruit & Dried Fruit Packaging Machine Moisture-Resistant Pillow Pack

Packaging preserved fruits and dried fruits is one of the most technically demanding applications in food packaging. Products arrive at the wrapping station coated in sticky sugar syrup, with high internal moisture content, irregular shapes, and delicate surfaces that bruise easily. Standard flow wrappers fail quickly in this environment — seals fail due to sugar contamination, product residue builds up in inaccessible corners, and delicate fruit pieces are crushed by aggressive feeding mechanisms.

The Junyao JY-ZB900 was designed specifically for this challenge. Drawing on installation experience from preserves manufacturers in over 25 countries, this machine incorporates a moisture-resistant sealing system, a gentle feeding mechanism, and a tool-free clean-in-place design — each feature addressing a specific failure mode that our engineers have observed (and solved) in the field.

One data point our customers care about: On standard wrappers, leaker rates for high-syrup preserved fruits can reach 5–8% due to seal contamination. The JY-ZB1000PF's moisture-resistant sealing system reduces this to well under 1% in typical applications — directly improving product shelf life and reducing customer complaints.

1. Moisture-resistant sealing system. Independently controlled upper and lower sealing jaws with precision PID temperature regulation. The jaw geometry is designed to displace sugar syrup and fruit juice from the seal area before heat is applied. Sealing temperature is adjustable from 100–220°C, and operators can fine-tune settings based on the specific product's moisture level and the film material being used.

2. Gentle feeding for delicate fruit products. A low-friction conveyor belt with soft-product-compatible cleats transports preserved plums, dried mango strips, and candied fruits from infeed to wrapping station without bruising or deformation. The feed speed is electronically synchronized with the film feed — products are positioned correctly without impact or bouncing.

3. Tool-free cleaning—15 minutes between products. Sugar residues from preserved fruits are among the hardest substances to remove from packaging machinery. The JY-ZB900's key contact components — feeding belt, sealing jaw covers, film guide plates — are removable without tools. The open frame architecture has no dead corners or recessed pockets where residue accumulates. Product changeover cleaning: typically under 15 minutes, compared to 45+ minutes on conventional machines.

4. Food-grade 304 stainless steel throughout. Every surface that contacts product or packaging film is 304 stainless steel with a surface finish of Ra <0.8 μm. This resists corrosion from acidic fruit products, prevents residue adhesion, and complies with FDA and EU food contact material regulations.

5. 50-product recipe memory. When switching from packaging green plums to dried mango strips, the operator selects the stored recipe — all temperatures, speeds, film lengths, and registration settings are recalled instantly.
