In the fields of feed processing, harmless treatment of livestock and poultry, and resource utilization of agricultural and forestry solid waste, batch cooker is a pivotal process that determines product quality, production efficiency, and environmental compliance. However, traditional batch cooker has long suffered from prominent drawbacks including steam leakage, high energy consumption,uneven thermal treatment, easy scaling and corrosion, as well as complicated operation and maintenance. These issues range from incomplete sterilization and inconsistent cooking degree to energy waste, frequent failures, and limited production capacity, seriously troubling many production enterprises. Confronted with multiple challenges such as complex material composition, large fluctuations in moisture content, and stringent sterilization standards, conventional jacketed kettles or old batch cooker often fall into the dilemma of “local scorching” and “sterilization blind spots”.

To address existing production bottlenecks in the industry and satisfy the standardized manufacturing needs of modern industry, Sunrise has launched its self-developed intelligent batch cooker.The equipment is built in compliance with the GB/T 150-2011 pressure vessel standard and incorporates two proprietary core patents: safety interlocking and heat recovery.It integrates high-temperature sterilization, material maturation, energy saving and consumption reduction, intelligent control, and multiple safety protection functions,achieving a comprehensive technological innovation over traditional cooker It acts as a flagship core machine for feed processing and organic solid waste eco-treatment.

This mid and high end industrial-grade batch cooker boasts core advantages such as precise processing, regulatory compliance and safety, energy efficiency, stability and durability. Tailored to meet large-scale, standardized mass production demands across multiple sectors, it delivers superior overall compatibility and reliable on-site operational performance.It can professionally handle various organic solid wastes such as diseased and dead livestock and poultry, slaughter by-products, and kitchen waste,and completes the harmless treatment through high-temperature and high-pressure sterilization and hydrolysis decomposition. All indicators fully meet the relevant environmental protection and harmless treatment standards.

Sunrise batch cooker, relying on the headquarter Chengzhu’s sealing patent and Sunrise’s safety interlocking and heat recovery patent technologies, have achieved a comprehensive upgrade in four dimensions: structure, energy consumption, safety, and process, compared to traditional simple cooker with single-stage sealing and lack of protection.The equipment features a multi-level high-temperature and corrosion-resistant fluororubber combined sealing structure, which can stably adapt to 200℃ high-temperature steam conditions.Even under long-term, high-frequency start-stop conditions, it can maintain zero leakage under tank pressure,eliminating steam waste and safety hazards. Combined with a patented intelligent safety interlock system that links pressure, temperature, and door functions, it offers millisecond-level instantaneous response. This system eliminates the risks of unauthorized operations such as opening doors under pressure and exceeding temperature and pressure operation,offering all-round protection for pressure vessel operation safety. It employs a combination of saturated steam multi-point distributed heating and variable frequency dynamic stirring,along with a continuously variable frequency stirring system that allows for flexible speed adjustment based on material properties. This completely resolves industry pain points such as localized high temperatures, undercooked materials, and uneven sterilization associated with traditional equipment.It delivers highly consistent material maturation and sterilization efficiency across every batch, enabling stable, controllable finished product quality. Furthermore,heat recovery technology efficiently recovers waste heat, significantly reducing steam consumption and lowering enterprise production and operating costs.The entire machine strictly complies with GB/T 150-2011 pressure vessel standard. Before leaving the factory, it undergoes dual testing for water pressure and air tightness at 1.25 times the rated working pressure, and all safety fittings and automatic control instruments are fully compliant. It can pass the annual inspection of special equipment smoothly and fully meet the production compliance requirements across feed processing and environmental protection sectors.

To meet the diverse production demands of different enterprises based on distinct material properties and production capacity, this batch of cookers supports personalized specification selection and precise adjustment of process parameters, covering a full range of models with volumes from 0.5m³ to 20m³. Enterprises can pick the scientifically matched model based on their daily processing capacity, batch operation frequency and material filling factor. The tank is designed with ample reserved space for material expansion and stirring movement.This design effectively eliminates drawbacks triggered by overloaded operation, including degraded material maturation performance and accelerated equipment wear.It thoroughly resolves two common industrial bottlenecks: substandard maturation results and constrained throughput caused by mismatched equipment models and parameter settings.Meanwhile, to resolve the scaling and corrosion troubles caused by high-temperature steam and organic residue, standardized operation and maintenance solutions are implemented for different operating conditions: light loose scale is cleaned with high-pressure water, while heavy hard scale is cleaned and neutralized by constant-temperature circulation of a citric acid solution of appropriate concentration, and slight corrosion is treated with high-temperature anti-corrosion after polishing.The tank wall thickness and pressure bearing performance are strictly controlled throughout the process to ensure stable operation of the equipment,effectively extend the service life of the equipment, and reduce the long-term operation and maintenance costs of enterprises.

Before starting up each batch of cookers, the tank sealing, safety interlock sensitivity, instrument calibration accuracy, and steam pipeline unobstructedness are strictly checked.During operation, temperature, pressure, and steam flow are monitored in real time, and parameters are adjusted dynamically in small steps. The replacement cycle of vulnerable parts such as sealing rings, seals, valves, and sensors is clearly defined to avoid operating with defects. After each shutdown, operators shall promptly clear residual materials,drain residual tank water, and implement anti-rust & dust-proof protection. Clear standardized protocols are defined for both short-term routine maintenance and long-cycle overhaul,drastically cutting equipment failure rates and enabling sustained long-term continuous production.

Compared to traditional batch cooker, Sunrise’s patented batch cooker truly achieves upgrades in safety, energy saving, process, compliance, and operation and maintenance.Based on national standard pressure vessel quality and with patented technology at its core, it not only solves the problems of low production efficiency and unstable material quality for enterprises, but also meets the core requirements of energy saving, cost reduction, safety compliance, and long-term durability.

Whether for standardized material maturation and sterilization in feed production, or harmless and resource-based treatment of organic solid waste, Sunrise’s intelligent,patent-backed and fully compliant batch rendering cooker serves as an ideal solution for manufacturers to slash operating costs, raise production efficiency and reinforce core competitiveness.
