Guangdong Quanrun Dingwei Food Technology Co., Ltd

Against the backdrop of consumption upgrading and rising food safety requirements, the frozen dumpling market is undergoing an accelerated transition from “quantity growth” to “quality improvement”. As a benchmark enterprise specializing in Cantonese dim sum and frozen food, a Guangdong food technology company based in Nanhai, Foshan focuses on the R&D, production and sales of high-quality dumplings. It has recently introduced a 1.0T Kaida variable-frequency steam generator. Driven by equipment upgrades and process innovation, the enterprise has fully consolidated its quality control for dumplings and stepped into a new phase of standardized, high-efficiency and energy-saving production.

Project Overview

Founded in 2023, this Guangdong food technology company centers on core products including frozen dumplings and Cantonese dim sum, and has built a full industrial chain management system covering raw material selection, processing and production, and cold-chain distribution. The company features a 100,000-class stainless steel fully refrigerated purification workshop, ultra-low-temperature spiral quick-freezing warehouse and automatic cooking lines, with an hourly output of 2 tons. It can cater to diverse scenarios such as catering chains, supermarket retail and group meal customization.

Adhering to the product philosophy of “thin wrapper, generous filling, fresh mellow flavor and healthy zero additives”, its dumplings are made from premium flour, fresh meat and seasonal vegetables without preservatives or artificial flavors. Thanks to consistent quality and authentic taste, the products have won wide recognition among consumers in South China.

With continuously growing order volume and intensifying market competition, the food enterprise has clearly identified pain points of conventional steam equipment: long preheating time, unstable temperature control, high energy consumption and mandatory dedicated on-site operators. These issues tend to cause uneven cooking, inconsistent texture and nutrient loss of dumplings, alongside high annual inspection costs and safety hazards, making traditional equipment incapable of supporting high-quality mass production. To break production bottlenecks and consolidate quality foundations, after multiple rounds of on-site inspections, working condition adaptation tests and industry case studies, the enterprise finally selected the Kaida 1.0T variable-frequency steam generator as the core steam supply unit for its dumpling production line, embarking on a new journey of quality upgrading.

Project Highlights

The newly deployed Kaida 1.0T variable-frequency steam generator is customized for food processing scenarios. With four core strengths: instant steam generation within 5 seconds, precise temperature control of ±1℃, inspection exemption and high energy efficiency, it perfectly meets the requirements of the full workflow of dumpling steaming, proofing and sterilization, and is highly aligned with the high-quality production philosophy of Quanrun Dingwei.

1. Precise Temperature Control to Lock in Original Flavor The quality of dumplings hinges on temperature and steam stability during steaming. Equipped with an intelligent variable-frequency control system, the Kaida variable-frequency steam generator delivers precise temperature control within ±1℃ and outputs high-temperature clean steam. Steam penetrates evenly through dumpling wrappers and fillings, avoiding partial overcooking, undercooking, nutrient loss or dry texture. It maximally preserves the original flavor of ingredients, producing dumplings with soft, resilient wrappers and tender, juicy fillings.
2. High Efficiency & Stability to Boost Production Capacity Featuring a modular design, the unit starts and generates steam in 5 seconds, eliminating the 30-minute preheating period. It supports on-demand startup and on-demand energy supply, perfectly matching the characteristics of the dumpling production line with concentrated steam demand and intermittent operation. With a rated evaporation capacity of 1.0T, it reliably supports full-load operation of the automatic cooking line, maintaining stable steam pressure at 0.4 MPa. It ensures consistent doneness and uniform quality across batches in mass production, lifting production capacity by over 30% and easily handling large-volume orders.
3. Inspection-Exempt Safety Design for Cost Reduction & Efficiency Gain Different from traditional high-pressure boilers, the Kaida steam generator has a water volume of less than 30L and is not classified as special equipment. No installation filing or annual inspection is required, removing cumbersome approval procedures and the cost of dedicated operators, and greatly lowering safety risks and management expenses. The compact footprint allows it to be embedded into existing production lines without large-scale plant renovation. With fully automatic intelligent control including one-click start-stop and automatic descaling, it can be operated by ordinary staff after simple training, effectively cutting labor costs and downtime for maintenance.
4. Cleanliness & Energy Saving for Green Production Food processing imposes strict requirements on steam cleanliness. The Kaida steam generator adopts a 316L stainless steel heat exchanger to prevent rust and contamination. The delivered steam is impurity-free and odorless, complying with food-grade hygiene standards. Equipped with direct-current condensation technology, it achieves a thermal efficiency above 95%, saving 20%–60% energy compared with conventional steam equipment. Powered by clean energy, it achieves NOₓ emissions below 30 mg/m³, far lower than national standards. It helps the enterprise realize green and low-carbon production and fulfill environmental responsibilities.
