When choosing a juice filling machine, it is necessary to comprehensively consider factors such as production needs, equipment performance, cost-effectiveness, and after-sales service. Here are the key purchasing points, sorted out in steps for you:
1. Clarify production requirements
Production scale
Small businesses (such as workshops and restaurants) can choose semi-automatic or single head filling machines (100-500 bottles/hour).
Medium sized enterprises (1-5 tons per day): Fully automatic linear filling machine (500-2000 bottles/hour).
Large scale enterprises (mass production): Rotary multi head filling lines (2000 bottles/hour or more) require supporting equipment such as sterilization and labeling.
Juice characteristics
Viscosity: For orange juice (including pulp), a filling machine with stirring function should be selected to avoid sedimentation; Clear juice (such as apple juice) can be selected as regular type.
PH value/corrosiveness: Acidic fruit juice (such as lemon juice) requires 316 stainless steel material, while ordinary fruit juice can be made of 304 stainless steel.
Whether it contains gas: carbonated fruit juice shall be equipped with anti foam filling valve and pressure system.
2. Core equipment parameters
Filling accuracy
Require ± 1% error (such as 500ml packaging error ≤ 5ml), high-precision requires servo motor or flow meter control.
Filling method
Atmospheric pressure filling: suitable for clear juice and low viscosity juice, with low cost.
Negative pressure filling: suitable for high-end fruit juices that are prone to oxidation (such as NFC juice), reducing exposure to air.
Gravity filling: suitable for high viscosity jam or fruit juice with granules.
Container adaptability
Bottle types: glass bottles, PET plastic bottles, cans, etc., with adjustable filling height (e.g. 200-400mm adjustable).
Bottle mouth diameter: The equipment needs to be adapted to different diameters (such as Φ 20-50mm).
3. Key configurations and materials
Contact component material
Food grade 304/316 stainless steel (material certification required), with sealing components made of silicone or PTFE (acid and alkali resistant).
degree of automation
Basic type: manual bottle loading+automatic filling (price 50000 to 100000 yuan).
Fully automatic type: automatic bottle washing, filling, and capping integrated (priced between 150000 and 500000 yuan, such as brands like Krones and New Meixing).
Additional features
Nitrogen protection (oxidation prevention), hot filling (high-temperature resistant design required for filling above 85 ℃), CIP cleaning system.
4. Supplier evaluation
after-sales service
Warranty period (at least 1 year), whether local technical support is provided, and spare parts supply speed (such as response within 48 hours).
Case Reference
Request to provide successful cases of juice factories of the same type (such as a 1000 bottle/hour mango pulp filling line).
certification standard
Passed CE, FDA or GB 12073-2010 (Food Machinery Safety Standard).
5. Cost accounting
equipment budget
Semi automatic: 30000 to 80000 yuan; Fully automatic entry line: 150000 to 300000 yuan; High end import line: 500000 to 2 million yuan.
implicit cost
Energy consumption (such as hourly electricity consumption), labor costs (fully automated lines can reduce 2-3 people), and maintenance costs (approximately 5% of the annual equipment price).
6. Field testing and verification
Test requirements
Test with the actually produced juice samples and observe the filling effect (such as drip and foam control).
Efficiency verification
Run continuously for 1 hour and check stability (such as bottle sticking rate<0.1%).
