Practical Problems Solved
This professional poultry scalding equipment solves typical pain points of medium and large suspended slaughter lines, including uneven manually controlled scalding temperature, inconsistent follicle loosening effect, serious steam heat loss, frequent manual water level adjustment, and unstable plucking quality caused by non-standard pre-scalding process. Unqualified scalding results easily lead to residual fine feathers, skin rupture and reduced finished product rate.
Customized for industrial slaughterhouse working conditions, this U-type constant temperature scalding machine adopts a closed box structure and water circulation stirring system to realize automatic constant temperature control and automatic water replenishment, greatly reducing manual operation errors. The optimized air turbulence and water circulation structure achieves full-range uniform scalding, perfectly adapting to the high-humidity and frequent-cleaning working environment of commercial slaughterhouses.
Working Principle
Poultry carcasses are suspended on conveyor hooks and pass through the U-type constant temperature scalding tank at a stable linear speed to complete standardized pre-scalding before entering the main plucking unit. The built-in fan air distribution system and circulating water tank produce continuous rolling water turbulence, completely eliminating local temperature differences inside the tank.
Precise constant temperature heating ensures stable scalding temperature and fixed scalding time, fully loosening poultry follicles without damaging skin and meat quality. The automatic water replenishment system maintains a stable water level in real time, and floating impurities are continuously circulated and filtered to keep the scalding water clean and ensure consistent scalding results for each batch of poultry.
Practical Note: Stable scalding temperature and standardized scalding duration are core prerequisites for a 99.9% scalding qualification rate and ultra-low damage rate. We will confirm and customize the optimal process parameters according to customers’ poultry types and production requirements during pre-delivery technical communication.
Main Structure & Component Breakdown
1. Thickened Stainless Steel Tank Body The whole machine adopts food-grade stainless steel material with 2mm tank thickness and 1.0mm cover thickness. It features high temperature resistance, corrosion resistance, rust-proof performance and easy daily cleaning, fully complying with international food hygiene standards and ensuring long service life.
2. Closed Heat Exchange Heating System Adopts indirect heat exchange heating mode to avoid direct high-temperature scalding and poultry skin burning. The fully closed box structure minimizes steam overflow and heat loss, realizing energy-saving operation while protecting complete poultry skin quality.
3. Fan Air-distribution Turbulence Device Equipped with high-efficiency fan and evenly arranged air outlets to form three-dimensional rolling water flow inside the tank. It balances water temperature in all directions without scalding dead corners, ensuring uniform soaking and consistent heating for every poultry carcass.
4. Automatic Constant Temperature & Water Replenishment Assembly Optional full-automatic temperature control system with high precision and wide adjustable range. Matched with automatic water replenishment structure to stabilize tank water level in real time, avoiding production shutdown caused by insufficient water and ensuring continuous stable line operation.
5. Water Circulation Lifting & Filtration System The circulating water tank continuously lifts and circulates tank water to accelerate water flow and improve scalding uniformity. It filters floating feather debris during operation to effectively reduce cross-contamination risks in food processing.
Verified Performance Advantages
1. Stable Scalding Effect & High Finished Product Rate The full-range constant temperature and rolling water design fully relax poultry hair follicles. Cooperated with subsequent plucking machines, the overall feather removal rate reaches 99.9%, and the poultry skin damage rate is controlled within 0.1%, greatly improving finished product qualification rate.
2. Energy-saving Design & Lower Production Cost The closed box structure greatly reduces steam and heat loss. The heat exchange heating mode improves thermal energy utilization efficiency, effectively reducing long-term energy consumption and production costs for slaughter factories.
3. Food-grade Hygiene & Easy Maintenance All material contact parts adopt food-grade stainless steel, resistant to organic waste corrosion and frequent high-pressure washing. The assembled structure supports partial disassembly and cleaning without sanitary dead corners, meeting international food safety standards.
4. Industrial Continuous Production Capacity Capable of 24-hour non-stop industrial continuous operation. Full specifications from 100BPH to 10000BPH perfectly match the operation rhythm of small, medium and large automatic suspended slaughter lines.
5. Modular Customization & Strong Compatibility Adopts flexible modular assembly design. The tank length and equipment configuration can be customized according to workshop space, slaughter capacity and poultry types, suitable for new slaughter projects and upgrading of old production lines.
