Industrial Chocolate Melting Tank and Buffer System

AkayGAM industrial chocolate melting tanks are fully manufactured from AISI 304 stainless steel and can operate as a melting unit and as a buffer tank for continuous production. Reinforced walls support heavy loads, while the water jacket provides uniform heat transfer for stable holding temperature. Depending on model, options include scrapers for improved circulation, a chocolate transfer pump, and a sieve filter to protect downstream equipment.

These tanks melt solid chocolate and maintain stable temperature and viscosity while supplying downstream equipment such as tempering machines, enrobers, and depositors.

Chocolate melter models and configurations

Besides compact laboratory units, we manufacture cylindrical and rectangular chocolate melters for small workshops and medium-scale confectionery production. Units can be equipped with casters for mobility or optional load cells for accurate batch weight control.

Available in capacities from 100 kg to 1000 kg, machines can be configured with transfer pumps, filtration systems, and automation interfaces for integration into industrial chocolate production lines.

ST and CMT series are cylindrical melting tanks optimized for melting chocolate drops or callets, while CBM series rectangular tanks are designed for efficient melting of solid chocolate blocks.

Chocolate melting tank as buffer in production lines

In production lines, the melter often works as a buffer: stable holding temperature (water jacket + controlled agitation) keeps viscosity consistent for pumping, dosing, and enrobing. Transfer is typically performed by a gear- or lobe-type chocolate pump sized to the required line flow. When installed, a sieve filter reduces the risk of particles reaching narrow passages in valves, dosing components, and tempering equipment.

If recirculation or return chocolate is used, the return should be reheated to the melter temperature (e.g., via a decrystallization tube) to avoid temperature shocks that force large PID corrections and disturb viscosity stability.

Vertical cylindrical vs rectangular block melter (with melting grid)

Chocolate melters are typically selected by input format and production workflow. Cylindrical tanks are usually preferred for couverture drops, callets, rework and liquid chocolate buffering. Rectangular block melters are optimized for solid blocks and fast melting through a dedicated melting grid.

  • Cylindrical tank (ST / CMT): stable holding temperature, controlled agitation, and practical pump feeding to downstream equipment.
  • Rectangular block melter (CBM): higher block melting practicality by creating a controlled melt interface on the grid while the reservoir remains stable.
  • Why grid heating matters: it accelerates phase change where the block touches the grid instead of forcing the entire mass to heat up aggressively.
  • Clean circulation option: a sieve filter protects the pump and reduces the risk of inclusions or packaging residues entering downstream process components.

How to choose the right chocolate melting tank

For engineering-level selection, the critical inputs are chocolate format (drops vs blocks), target flow rate, and whether the melter will also work as a buffer feeding tempering, enrobing, or depositing.

  • Input format: drops/callets and liquid chocolate are typically handled efficiently in cylindrical tanks; block loading is more practical with a rectangular tank and melting grid.
  • Flow stability: when feeding a process line, stable temperature and viscosity control is usually more important than maximum heating power.
  • Circulation hygiene: filtration supports pump protection and reduces the chance of particles reaching valves, dosing systems, or tempering equipment.
  • Automation level: load cells, intermittent mixing logic, and alarm-ready temperature control simplify batch repeatability.

Chocolate from the melter can be transferred to the storage tank to keep the melter ready for the next batch. If the system is also used for resting, it is important to avoid temperature fluctuations caused by returning tempered chocolate directly to the reservoir. Tempered chocolate should be reheated to match the temperature of the chocolate inside the melting tank. Use a decrystallization tube for controlled chocolate reheating.
