The CE Industrial Raisin Sterilizer is a state-of-the-art machine designed for UV and heat sterilization of raisins and dried fruits. Combining advanced ultraviolet technology with controlled heat, it eliminates pathogens (e.g., E. coli, Salmonella) while preserving nutritional value and flavor. Ideal for food processors and exporters, this sterilizer ensures compliance with international food safety standards (e.g., EU Regulation (EC) 852/2004) and reduces reliance on chemical sanitizers.
Dual Sterilization
Integrates 12 UV-C lamps (254nm wavelength, 30W each) and hot air (60-80°C) for multi-stage disinfection, ensuring thorough pathogen reduction.
Conveyor Belt System
0.8m-wide Teflon-coated mesh belt with adjustable speed (0.5-2m/min), allowing processing of different product thicknesses.
PLC Touchscreen
Real-time monitoring of temperature (±1°C accuracy), UV intensity (via built-in sensors), and processing time, with automatic alerts for deviations.
Stainless Steel Chamber
316L stainless steel construction (resistant to acid from dried fruits) with polished interior to maximize UV reflection.
Energy Recovery
Heat exchanger recycles 60% of heat from exhaust air, reducing energy consumption by 35% compared to single-stage sterilizers.
Effective Pathogen Reduction
Achieves log 4 reduction of bacteria, yeast, and mold, exceeding the safety requirements for both domestic and export markets.
Nutrient Retention
Controlled heat and short UV exposure minimize vitamin C and antioxidant degradation (retaining >90% of original levels) compared to steam sterilization.
Cost-Effective
Low energy consumption (8kW/hour) and minimal maintenance requirements (annual lamp replacement) reduce operational costs.
CE Certification
Compliant with EU health and safety regulations, facilitating access to European and global markets requiring CE marking.
Flexible Operation
Suitable for various dried fruits, including cranberries, apricots, and figs, with adjustable settings for moisture content (10-30%).
Does the UV light affect the color of raisins?
UV-C exposure is limited to 10-15 seconds and controlled, ensuring no significant color change (ΔE <2) as verified by spectrophotometer testing.
What is the sterilization capacity?
The machine processes up to 300kg of raisins per hour, with adjustable belt speed to match upstream drying equipment.
Is installation support provided?
Yes, our team offers on-site installation, including electrical connection (3-phase 400V) and calibration, plus 3 days of operator training.
How often do UV lamps need replacement?
UV lamps have a service life of 8,000 hours (approximately 1 year under 24-hour operation), with a built-in timer alerting for replacement.
