Technical Specifications

Washing Process Details

Multi-stage washing ensures thorough cleanliness:

• Stage 1: External spray washing (recycled water) – removes loose debris
• Stage 2: Internal high-pressure rinse (recycled water) – dislodges contaminants
• Stage 3: Internal disinfection (ozone or chlorine solution) – kills microorganisms
• Stage 4: Fresh water rinse (potable water) – removes residual disinfectant
• Stage 5: Drip/drain station – removes excess water

Water recycling system: Modern machines include water recovery tanks and filtration, reducing fresh water consumption by 40-60% compared to single-pass systems.

Filling System

• Filling method: Gravity filling or pressure filling
• Level control: Mechanical float sensors or electronic level detection
• Anti-drip nozzles: Prevent water waste and contamination
• Material: SUS304 stainless steel contact parts
• CIP system: Clean-in-place capability for sanitation

Capping System

• Cap orientation: Automatic cap sorter and orienter
• Cap application: Pneumatic or mechanical cap placement
• Torque control: Adjustable torque settings (2-5 N·m typical)
• Cap types: Compatible with standard 55mm neck finish caps
• Rejection: Automatic rejection of improperly capped buckets

20L Bottle Neck Label Shrinking Machine

los automatic steam film shrinking machine is manufactured and developed according to customer needs, designed for application before 3-gallon and 5-gallon washing and filling operations. This machine has been widely welcomed by bottled water factories globally.

Machine Function

The neck label shrinking machine applies heat-shrinkable labels to the bottle neck, providing:

• Product branding and information display
• Tamper-evident seal for consumer safety
• Professional appearance and market competitiveness

Technical Specifications

Working Process

1. Label feeding: Pre-cut sleeve labels loaded into magazine
2. Label application: Mechanical or vacuum-based label placement on bottle neck
3. Conveying: Labeled bottles enter shrinking tunnel
4. Heat shrinking: Steam or electric heating shrinks label to conform to bottle contour
5. Cooling: Natural or forced air cooling sets the label
6. Discharge: Finished bottles exit to next station

Advantages of Steam Shrinking

• Uniform heating for consistent label appearance
• Energy-efficient compared to electric heating
• Gentle on heat-sensitive PC bottles
• Lower operating cost in facilities with existing steam supply

FAQ: 5 Gallon Bottling Equipment

Production capacity ranges from 100-600 buckets/hour depending on the model and configuration. Semi-automatic systems typically achieve 100-200 buckets/hour, while fully automatic monoblock systems can reach 400-600 buckets/hour with proper line integration.

Yes, most machines are designed for 3-5 gallon (11-19L) PC bottles with standard 55mm neck finish. Change parts may be required for different bottle diameters or heights. Consult with CHIWATEC engineers for your specific bottle specifications.

Typical requirements: 380V/50Hz 3-phase power (3-7.5 kW), compressed air 0.5-0.7 MPa, water supply (0.3-0.5 L per bucket with recycling), and proper drainage. Steam models require 0.3-0.5 MPa steam supply.

Typical timeline: 3-7 days for machine installation, 2-3 days for utility connections, 3-5 days for testing and operator training. Total project completion usually takes 2-3 weeks including water treatment system integration.

With proper maintenance, 5 gallon bottling machines have a lifespan of 10-15 years. Key wear parts (seals, sensors, pneumatic components) should be replaced every 1-2 years. Regular preventive maintenance extends equipment life significantly.
