Chocolate Holding Tank Equipment Manufacturers
As a professional Chocolate Holding Tank Equipment Manufacturer and supplier, Suzhou Golden Eagle Machinery & Equipment Co., Ltd. designs and builds the QBJ series holding tanks that keep chocolate mass at a precise temperature between refining and downstream processing. With nearly 30 years in chocolate machinery, we supply tanks from 30L laboratory units to 5000L production vessels, engineered for continuous lines producing moulded bars, enrobed biscuits, pralines, and chocolate chips.
Our factory in Suzhou, China, integrates manufacturing, quality control, and engineering support. We hold ISO9001 certification and CE marking, and our tanks are used by food companies across China and exported to over 50 countries. the category explains our holding tank range, how it fits into your production flow, and the project data we need to configure the right solution.
Our Holding Tank Range and Application Fit
The QBJ series is our dedicated chocolate holding tank line. It stores chocolate paste after fine grinding (from ball mill or conche) and supplies a stable, uniformly tempered mass to tempering machines, moulding plants, or enrobing lines. The tanks also serve as melters for chocolate blocks or couverture, maintaining fluidity without overheating.

All models feature a double-jacketed design, geared motor drive, and a stirrer paddle that keeps chocolate in motion. The integral water heating system provides gentle, uniform heat transfer, preventing scorching and maintaining the temper of the mass.
Engineering and Configuration Approach
We build each holding tank around your process requirements. Standard tanks are fabricated from 304 stainless steel, with the option of all-stainless construction for full exterior coverage. For precise inventory control, we can add load cell weighing systems; for complete drainage, a conical bottom is available. High and low level controls integrate with your line automation.
Our engineering team works from your drawings or samples to develop custom tanks, including modifications to capacity, heating power, and dimensions. We also offer the QBJ tank as part of a complete chocolate production system, matching it with our Chocolate Conche, Chocolate Tempering Machine, and Chocolate Moulding Line to create a seamless flow.
Quality Assurance and Compliance
We implement inspection at each manufacturing stage, and finished tanks undergo a final test before leaving our factory. Our quality system is ISO9001 certified, and our products carry CE marking for the European market. We also provide inspection certificates with each shipment. Materials meet food-grade standards, ensuring no contamination of your chocolate mass.
Installation, Maintenance, and Support
We supply tanks with clear documentation for installation and operation. Our engineers are available for on-site commissioning support, and we offer training for your operators. Maintenance is straightforward: the modular design allows easy access to the agitator, heating elements, and controls. Spare parts are available from our factory, and we provide remote troubleshooting to minimize downtime.
Information We Use to Configure Your Solution
To prepare a precise proposal, we need the following project data:
- Required holding capacity (L) and desired throughput (kg/h)
- Chocolate type: dark, milk, white, or compound
- Viscosity and fat content of the mass
- Inlet temperature from upstream refining; required outlet temperature
- Available utilities: electrical supply (voltage/frequency), water heating source
- Space constraints and required dimensions
- Integration with existing tempering, moulding, or enrobing equipment
- Any need for load cells, level controls, or all-stainless exterior
Frequently Asked Questions
What is the difference between a holding tank and a melter?
Our QBJ holding tank is designed to store already-liquid chocolate mass at a controlled temperature. It can also melt solid chocolate, but for high-throughput melting of blocks or cocoa butter, we recommend our Chocolate Melter Tank series, which is optimized for faster melting.
Can the holding tank be connected to a tempering machine?
Yes. The QBJ tank is often placed upstream of a tempering machine, such as our QTJ or QYJ series. The tank maintains the chocolate at a pre-tempering temperature, ensuring a consistent feed to the tempering unit.
What temperature range can the tank maintain?
Standard tanks are equipped with an automatic temperature control system that maintains chocolate between approximately 40°C and 60°C, depending on the chocolate type. We can adjust the setpoint range based on your recipe.
Do you offer tanks with a conical bottom?
Yes, a conical bottom is available as an option. It facilitates complete drainage and easier cleaning, which is particularly useful when changing products frequently.
How do you ensure food safety?
All contact parts are made of 304 stainless steel, and the design avoids crevices where chocolate could accumulate. We also offer all-stainless exteriors for hygienic environments. Our manufacturing follows ISO9001 and CE standards.
