Working Principle
Poultry carcasses after plucking and washing are continuously conveyed into the spiral precooler. Adopting water as the core cooling medium, combined with circulating water system and blast cooling system, the equipment realizes omnidirectional heat dissipation and low-temperature soaking for chicken and duck carcasses.
The stable spiral propulsion system drives uniform forward movement of carcasses, ensuring every poultry body obtains consistent cooling time and temperature. It effectively removes lactic acid and toxins inside the carcass, realizes standard deacidification and detoxification, and guarantees uniform low-temperature state before segmentation processing.
Practical Note: Standardized precooling duration and stable cooling temperature are key to improving poultry meat quality and extending shelf life. We customize precooling time and operating parameters according to customer output, poultry types and processing standards in pre-delivery technical confirmation.
Main Structure & Component Breakdown
1. Full 304 Food-grade Stainless Steel Body The whole machine is made of standard 304 stainless steel, featuring corrosion resistance, low-temperature resistance, oxidation resistance and easy washing. It fully meets international food hygiene standards, no dirt accumulation, no sanitary dead corners, suitable for long-term slaughter workshop operation.
2. Spiral Propulsion Conveying System Adopts precision spiral pushing structure to ensure stable and orderly conveying of poultry carcasses. Realizes continuous feeding and discharging, avoids carcass stacking and uneven cooling, and supports uninterrupted industrial batch production.
3. Water Medium Circulating Cooling Structure Take water as the cooling medium for gentle and thorough carcass cooling. Matched with circulating water filtration system to keep cooling water clean, reduce secondary pollution, and ensure food safety during processing.
4. Auxiliary Blast Cooling Device Equipped with high-efficiency blast system to assist water cooling, accelerate surface heat dissipation of poultry carcasses, make internal and external temperature more uniform, and improve overall precooling efficiency and effect.
5. Core Driving & Power Components Configured with high-quality bearings, industrial motors and circulating water pump as core components, with stable output, low failure rate and strong continuous operation capability, meeting long-shift industrial production requirements.
Verified Performance Advantages
