Industrial Chocolate Storage Tank (Chocolate Holding Tank)
We manufacture vertical cylindrical chocolate holding tanks (heated chocolate storage tanks) designed for temperature-controlled storage of liquid chocolate with adjustable mixing. These jacketed chocolate tanks act as buffer reservoirs between refining, conching, tempering, molding, and coating stages for consistent industrial chocolate processing.
VIDEO ITemperature-Controlled Storage with Adjustable Mixing
Each chocolate storage tank is equipped with a low-speed agitator designed for high-viscosity chocolate mass. Agitation speed is adjustable and can operate in two modes:
This controlled agitation prevents sedimentation, maintains product homogeneity, and supports stable feeding to downstream equipment.
Heating is regulated by a PID-controlled water-jacket system that ensures uniform heat transfer and stable temperature throughout the chocolate tank.
Chocolate Holding Tank Range for Laboratory, Pilot, and Industrial Production
We manufacture chocolate holding tanks suitable for various production scales:
These tanks provide controlled buffer storage and enable stable feeding of tempering systems, enrobers, depositors or, molding lines.

Thermal Stability and Chocolate Structure Preservation
The insulated double-wall jacket maintains stable chocolate temperature during storage and feeding.
This helps preserve:
Insulation and Agitator Configuration
Chocolate holding tanks can be supplied with or without glass wool insulation, depending on model and application requirements. Insulated chocolate storage tanks provide improved thermal efficiency and reduced heat loss, particularly in medium and large industrial installations. Compact models ST100, ST200, ST400 and ST600 are supplied without insulation and are suitable for laboratory, pilot, and small-scale production or for use in temperature-controlled environments.
The agitator system is designed specifically for high-viscosity chocolate mass and is equipped with side-wall scrapers as standard on all models. These scrapers, made from stainless steel or Teflon, prevent chocolate accumulation on tank walls. This supports a homogeneous chocolate structure during storage across all tank capacities.
Role of Chocolate Holding Tanks in Production Lines
Chocolate holding tanks provide temperature-controlled intermediate storage between processing stages and support stable production flow. They are typically installed after:
They act as an intermediate reservoir and supply chocolate reliably to:
Important Process Considerations
Chocolate returned from tempering or processing equipment must be reheated to the storage temperature before re-entering the holding tank. This is done using a chocolate decrystallization tube, which stabilizes the chocolate structure and prevents uncontrolled crystallization.
These tanks stabilize chocolate temperature and enable controlled feeding of downstream equipment during continuous production. ST100, ST200, ST400, ST600, and CMT1000 function both as chocolate melters and storage tanks, allowing solid chocolate to be melted and stored in the same tank. ST2000 and ST3000 are designed exclusively for storage and temperature maintenance of liquid chocolate and cannot be used for melting solid chocolate.
Key Engineering Characteristics of Chocolate Holding Tanks
How to Select the Correct Chocolate Holding Tank Capacity
Capacity should be selected based on throughput, buffer time, and downstream consumption rate. Typical sizing guidance:
Related equipment
Chocolate decrystallization tubes are used for controlled reheating of chocolate before returning it to the storage tank, ensuring proper temperature stabilization before storage.
ST100, ST200, ST400, ST600, and CMT1000 are chocolate storage tanks that can also be used as melters.
Frequently Asked Questions
Quick answers about the ST & CMT.
What is a chocolate holding tank used for?
A chocolate holding tank is used to store liquid chocolate under controlled temperature and mixing conditions and to feed chocolate reliably to tempering, molding, coating, and depositing equipment.
Can a chocolate holding tank melt solid chocolate?
Yes, selected models can be used as chocolate melters. ST100, ST200, ST400, ST600, and CMT1000 are suitable for melting solid chocolate (chips, drops, or blocks) and for temperature-controlled holding with mixing.
ST2000 and ST3000 are designed for storage and temperature maintenance of liquid chocolate and are not intended for melting solid chocolate. For these capacities, solid chocolate should be melted in a dedicated chocolate melting tank before transfer.
Why is agitation needed in a chocolate storage tank?
Agitation prevents sedimentation, improves heat distribution through the jacketed tank wall, and keeps the chocolate mass homogeneous during storage.
