Electric Heating Double-Deck Water Bath Sterilization Pot – Product Introduction

The electrically heated double-layer water bath sterilization pot is a specialized piece of equipment designed to meet the sterilization needs of multiple industries. It features a dual-layer structure combined with electric heating, leveraging the principle of water bath circulation for sterilization. While ensuring stable sterilization performance, it also emphasizes energy efficiency and ease of operation. Widely used in fields such as food, beverages, pharmaceuticals, and deep processing of agricultural and sideline products, this equipment provides a reliable solution for the sterilization of various packaged products, helping enterprises enhance product storage stability and ensure that product quality meets standards.

Core Structure and Working Principle of the Product

The equipment features a dual-layer design, with the upper layer serving as a hot-water storage and preheating tank, and the lower layer as the core sterilization tank. The entire unit is constructed from food-grade stainless steel (SUS304) or carbon steel (Q235-B), materials that comply with relevant industry hygiene standards. The surfaces are smooth and free of dead corners, making cleaning and maintenance easy. Additionally, the materials offer excellent corrosion resistance and high-temperature tolerance, thereby extending the equipment’s service life.

During operation, the water in the upper hot-water tank is first preheated to a preset temperature by an electric heating system. Then, a circulating pump transfers the hot water into the lower sterilization tank, ensuring that the product inside the tank is completely immersed in the hot water. At the same time, the hot water continues to circulate steadily, guaranteeing uniform and consistent temperatures at every point within the tank. By precisely controlling the heating power, sterilization temperature, and holding time, we can effectively eliminate any potentially harmful microorganisms present in the product, thereby achieving the desired sterilization effect. After sterilization is complete, the hot water can be recycled back to the upper storage tank for use in sterilizing the next batch of products, thus reducing energy and water consumption and improving production efficiency.

Core Product Advantages

1. Uniform and stable sterilization ensures product quality.

Using a water-bath circulation heating method combined with an optimized water flow exchange design, the sterilization tank achieves uniform temperature distribution throughout the entire process—ranging from heating and maintaining temperature to cooling. The temperature deviation can be controlled within ±0.5℃, effectively preventing situations where sterilization is either incomplete in certain areas or excessive. This ensures that the desired sterilization effect is achieved while maximizing the preservation of the product’s original color, flavor, and nutritional content, thereby helping to maintain a consistently high product quality. Additionally, an F-value meter can be optionally installed to monitor and record sterilization data in real time, facilitating production management and traceability.

2. Energy-efficient and highly productive, reducing production costs.

The electric heating method does not rely on steam boilers, is easy to install and use, and boasts high thermal energy utilization efficiency. Its double-layer structural design enables the recycling of hot water, reducing the frequency of hot-water heating and thereby saving energy and water resources compared to conventional single-layer equipment. Moreover, the preheating feature shortens the sterilization time per batch, boosting production efficiency. Over the long term, this approach can help enterprises reduce overall production costs.

3. Smart control for convenient and worry-free operation.

Equipped with a fully automatic control system powered by PLC programming and featuring a touch-screen operation interface, this equipment enables precise setting and automatic control of parameters such as sterilization temperature, holding time, and pressure. The entire sterilization process requires no continuous manual supervision; operators can quickly get started after undergoing simple training. The equipment supports seamless switching between manual and automatic modes, allowing flexible selection based on production needs. Additionally, it boasts an automatic sterilization process storage function, enabling pre-setting multiple sterilization protocols to meet the sterilization requirements of various products.

4. Multiple layers of protection for safe and reliable operation

The equipment is equipped with comprehensive safety protection devices, including dual overpressure protection—both electronic and mechanical—as well as automatic overtemperature protection, leakage protection, and safety interlock devices. These features ensure stable operation of the equipment even under high-pressure and high-temperature conditions, effectively eliminating potential safety hazards. Additionally, the equipment features abnormal alarm functions for temperature, pressure, and water level, promptly alerting operators to address any anomalies and thereby guaranteeing both production safety and equipment integrity. The reactor door seal utilizes an inflatable silicone rubber sealing ring that is temperature-resistant, providing reliable sealing and a long service life.

5. Wide compatibility and customizable adaptation requirements

The equipment is compatible with a variety of packaging types, including metal containers (tinplate cans, aluminum cans), plastic containers (PP bottles, HDPE bottles), and flexible packaging (aluminum foil bags, high-temperature vacuum bags, high-temperature retort pouches, etc.). It can be used for sterilization of a wide range of products, such as meat products, soybean products, dairy products, egg products, seafood, beverages, and snack foods. Standard models cover dimensions such as 700x1200 mm, 900x1800 mm, 1000x2200 mm, and 1200x3600 mm. Additionally, we can customize equipment with different sizes, power ratings, and control systems based on customers’ specific production requirements.

Applicable Industries and Scenarios

Widely used in the food processing industry (for sterilizing various canned goods, vacuum-packed foods, pre-prepared meals, and more), the beverage industry (for sterilizing fruit juices, health teas, bottled beverages, and other products), the pharmaceutical industry (for sterilizing certain formulations and packaging materials), as well as the chemical industry and the deep-processing sector of agricultural and sideline products, this technology can meet sterilization needs in batch production. It is flexibly adaptable for use by both small- and medium-sized enterprises and large-scale production lines.

Equipment Maintenance and After-Sales Service

The equipment features a modular design, with key components that can be quickly disassembled and replaced, making daily maintenance convenient. Compared to conventional equipment, it can reduce maintenance time by approximately 50%. The inner chamber of the equipment has a smooth surface with no dead corners, making it easy to clean and reducing cleaning workload as well as labor costs.

We provide comprehensive after-sales services. Our professional technicians can offer guidance on equipment installation and commissioning, as well as training for operators, based on the customer’s actual usage conditions, ensuring that customers can master the equipment’s operation skills proficiently. We also offer 24-hour technical support services to promptly address any issues customers may encounter during equipment use and maintenance. In compliance with relevant regulations, we provide the “Three Guarantees” service and lifetime maintenance support, guaranteeing the long-term stable operation of the equipment.

The electrically heated double-layer water bath sterilization pot, with its stable sterilization performance, energy-efficient and high-efficiency operation, convenient operation mode, and wide adaptability, has become the preferred equipment for sterilization processes across multiple industries. It helps enterprises enhance production efficiency, ensure product quality, and achieve large-scale, standardized production.
