Upgrade to flexible dehairing machines or laser singeing technology
Adopt precision slaughtering processes
Consistent product quality, reduced physical damage to carcasses, lower microbial contamination, improved efficiency.
Improper control of cooling time, temperature, and humidity affects muscle rigor and aging process, impacting taste, flavor, and water retention.
Implement intelligent cooling systems with two-stage cooling process
Use automated control systems to precisely manage temperature, humidity, and airflow
Ensure carcass center temperature reaches safety standards within required time
Superior meat taste and texture, extended shelf life, higher customer satisfaction, reduced shrinkage during storage.
Inadequate physical separation between clean and non-clean areas allows pollutants to flow from dirty areas to clean zones.
Implement strict unidirectional workflow from lairage to packaging
Establish physical barriers between different processing areas
Create clear zoning with defined contaminated, semi-clean, and clean areas
Install positive pressure ventilation systems to control airflow direction
Reduced product recalls, improved food safety compliance, lower risk of pathogen contamination, enhanced brand trust.
Inadequate cleaning and disinfection of knives, saws, hooks, and transport equipment makes them microbial cross-contamination vectors.
Implement CIP (Cleaning-in-Place) and SIP (Sterilization-in-Place) systems
Establish centralized knife sterilization stations with >82°C hot water
Automate cleaning processes for equipment like elevators and chutes
Enforce regular tool sterilization protocols
Consistent hygiene standards, reduced microbial load, extended equipment lifespan, lower manual cleaning costs.
Employees moving between areas without proper handwashing, disinfection, and clothing change procedures become mobile contamination sources.
Implement comprehensive and continuous food safety training programs
Restrict employee movement between different zones
Enforce strict changing, disinfection procedures when moving between areas
Establish clear hygiene protocols with regular audits
Reduced illness outbreaks, lower absenteeism, improved compliance with food safety regulations, enhanced company culture.
Improper evisceration techniques or outdated equipment often rupture intestines, stomach, or gallbladder, contaminating carcasses and edible by-products.
Implement robotic or automated mechanical evisceration systems
Use sensors and preset programs for precise organ separation
Train staff on proper evisceration techniques
Regularly maintain and update extraction equipment
Reduced contamination incidents, higher yield of saleable products, less rework and wasted carcasses, improved efficiency.
Manual inspection of viscera for lesions is labor-intensive, inefficient, and prone to fatigue-related errors and missed detections.
Implement machine vision technology with high-resolution cameras
Apply AI image recognition algorithms to detect abnormalities
Automate inspection processes to assist or replace manual inspection
Use data analytics to identify common defect patterns
Faster inspection throughput, more consistent detection of defects, reduced labor costs, valuable data collection for process improvement.
Unsanitary or untimely collection of内脏, blood, and other by-products with rough processing fails to maximize value and creates pollution risks.
Establish closed collection systems for blood, bile, and other by-products
Implement immediate cooling of by-products to maintain freshness
Develop specialized processing for high-value applications
Create separate clean rooms for by-product refinement
Additional revenue streams from by-products, reduced waste disposal costs, more sustainable operations, competitive advantage in specialty markets.
Scalding, rinsing, and cleaning processes require enormous amounts of hot and cold water, creating tremendous water usage.
Implement steam scalding or tunnel scalding systems
Use high-pressure, low-flow nozzles for cleaning
Adopt cold mist dust suppression systems instead of water rinsing
Install water meters to monitor usage patterns
Significant reduction in water costs, lower environmental impact, improved sustainability credentials, reduced wastewater treatment needs.
Water heating (scalding, cleaning) and refrigeration (rapid cooling, frozen storage) are major energy consumers with inefficient traditional equipment.
Install heat exchangers to recover waste heat from various processes
Use high-efficiency refrigeration units with variable frequency drives
Implement energy management systems for real-time monitoring
Upgrade to energy-efficient motors, pumps, and fans
Lower operational costs, reduced carbon footprint, eligibility for energy efficiency incentives, improved competitiveness.
Most slaughterhouses discharge wastewater directly without effectively recovering thermal energy and water resources for reuse.
Construct wastewater treatment plants to reclaim water
Implement medium water reuse standards for non-production purposes
Recover heat from hot wastewater for other processes
Develop circular water systems within the facility
Reduced freshwater consumption, lower energy costs for water heating, compliance with environmental regulations, enhanced corporate social responsibility image.
Higher quality meat products, premium pricing
Improved brand reputation
Higher quality meat products, premium pricing, improved brand reputation, reduced waste from poor quality meat.
Higher quality meat products, from poor quality meat.
This project is in Canada. It is the first pig slaughterhouse sold by ZBHT MACHINERY international team. The customer made a visit and talked with us in details. After they visited our workshop in Jiaoxi Industrial Zone, they were satisfied with our products and our engineer team.
This is a project in Zimbabwe, the daily slaughtering capacity for pig is 80 heads. About 30 heads will be put into chilling room, and cut into meat pieces after the aging procedure. About 50 of them will be sold to local market after split into halves.
