Shandong Longze Machinery Co., Ltd specializes in manufacturing industrial-grade professional pressure cookers (100L–800L) with four heating modes (gas, electromagnetic, steam, and thermal oil).our machines excel in high-volume food processing, sterilization, and cooking for industries like canned food production, ready-to-eat meals, pharmaceuticals, and chemical processing. With 14+ years of expertise, we’ve served 300+ clients across 45+ countries, delivering robust solutions tailored to global standards.
We have developed a pressure cooker based on the common pressure cooker, which is suitable for boiling bones and meat into soup, filtering materials and automatically producing soup. This is our company’s patent.
