Refrigeration system: suitable for ice cream processing and chemical industry.

Project name: Color Thread Refrigeration Project of Hongbaolai (Nanjing) Food Co., Ltd.

Completion date: December 10,2021, China Jiangsu Nanjing.

Project Overview: Covering 50,000 square meters, this facility specializes in large-scale, high-quality ice cream production. It provides comprehensive installation and construction services for refrigeration systems and processing equipment, with core operations spanning four key modules: freezing, quick-freezing, ice-making, and decorative thread processing. By precisely matching equipment performance with production workflows, the project achieves dual improvements in refrigeration efficiency and product quality, helping enterprises attain efficient, energy-saving, and stable production goals.

With the exception of the quick-freezing section, all other refrigeration systems employ a refrigerant-carrying system. This design utilizes a refrigerant as the intermediate medium to transfer cooling capacity, establishing a two-stage heat transfer model: "refrigerant-carrying agent-cooled object". Compared to direct refrigerant heat exchange systems, this approach demonstrates significant advantages in safety, compatibility, stability, and cost-effectiveness. It is particularly well-suited for large-scale, complex, long-distance, and multi-temperature zone cooling applications.

Installation of Core Equipment and Core Advantages

(1) 12 units of 1000L freezing machines with matching refrigeration equipment

As the core refrigeration equipment in ice cream production, the 12-unit 1000L freezing machines with integrated refrigeration systems utilize high-efficiency variable-frequency compressors and precision temperature control technology, delivering significant energy-saving advantages. The equipment dynamically adjusts operating power based on production load, reducing energy consumption by 15%-20% compared to traditional systems while rapidly achieving raw material freezing and shaping. Each unit can process 1000L of raw materials per hour, and the parallel operation of 12 units fully meets the production capacity requirements for large-scale manufacturing.

In terms of quality, the core components of the equipment are made of food-grade stainless steel, which is corrosion-resistant and easy to clean, meeting food production hygiene standards. The critical refrigeration pipelines have undergone high-pressure airtightness testing, ensuring strong sealing to eliminate refrigerant leakage risks and guarantee long-term stable operation. The intelligent monitoring module of the supporting refrigeration system can monitor key parameters such as temperature and pressure in real time, ensuring precise control of the freezing process and laying the foundation for the delicate texture of the ice cream.

(2) 1 unit of 2-ton/hour quick-freezer

The 2-ton/hour rapid freezer installed in this project employs high-efficiency air-cooled refrigeration technology. With an optimized airflow circulation design, it achieves rapid and uniform cooling, rapidly lowering the core temperature of finished ice cream to below-18°C. Compared to traditional equipment, the freezing time is reduced by 30%, significantly improving production efficiency while maximizing the retention of ice cream's flavor compounds and nutritional components. This achieves dual objectives of energy efficiency and quality preservation. During operation, intelligent defrosting technology minimizes frost layer interference with refrigeration efficiency, further reducing energy consumption.

In terms of quality, the inner tank of the freezer is manufactured using a single-piece 304 stainless steel molding process, eliminating hygiene dead zones and facilitating cleaning and disinfection. The conveyor belt is made of high-strength wear-resistant material, offering strong load-bearing capacity and long service life. The equipment is equipped with multiple safety protection devices, including over-temperature alarms and overload protection, ensuring safe and reliable production processes.

(3) 4-line 18-row ice cream pattern line processing equipment

The 4-line 18-row ice cream color line processing equipment features a modular design that integrates multiple functions including mixing, filling, molding, and decoration. With high production efficiency, a single production line can process a large quantity of colored ice cream per hour. Four parallel production lines can meet diverse and large-scale production demands. The equipment employs energy-saving motors for low energy consumption and stable operation. Additionally, precise material conveying and control technology reduce raw material waste, further enhancing production efficiency.

In terms of quality, all equipment components in contact with food are made of food-grade 304 stainless steel, complying with national food hygiene standards. Critical transmission parts undergo precision machining and heat treatment, ensuring high wear resistance and long service life. The equipment control system employs components from renowned brands, ensuring precise and reliable operation. It enables automated production of various ice cream flavors, guaranteeing consistent product quality.

Ice Cream Production Process

1. Raw material pretreatment: Mix milk, cream, sugar, and other ingredients according to the formula ratio, followed by homogenization and sterilization to ensure the stability and safety of the raw materials;

2. Cooling aging: The pretreated raw materials are fed into the cooling system, where they are rapidly cooled by the ice maker's cold source, then transferred to the aging tank for low-temperature aging to enhance the emulsification effect of the raw materials.

3. Freezing molding: The aged raw materials are fed into a 1000L freezing machine, where they undergo freezing under low-temperature and high-pressure conditions while being aerated to form a fine-textured ice cream structure.

4. Colorful processing: The frozen ice cream undergoes filling, shaping, and ingredient additions (e.g., chocolate, fruit pieces) using color line processing equipment to create a variety of colorful ice cream flavors.

5. Rapid Freezing and Refrigeration: The formed ice cream is rapidly frozen in a 2-ton/hour freezer to lock in flavor and texture, then transferred to a refrigerated storage unit for low-temperature preservation, completing the entire production process.

This project ensures efficient and stable ice cream production through precise installation and process optimization of a full suite of high-efficiency energy-saving equipment. It also helps enterprises reduce energy costs, improve product quality, and build a solid competitive edge in the ice cream market.
