XPTC

Continuous Tempering Machines

Horizontal continuous chocolate tempering machine.

Key functions

To give chocolate structure and crystallization

The continuous XPTC chocolate units are the ideal preliminary step for molding and coating processes. The objective of this unit is to impart the correct structure and crystallization of cocoa butter to the chocolate, both for subsequent processing and to maintain that structure once the product has been solidified and packaged.

Technology and operation

Innovation for precise and rapid tempering

XPTC units feature a frequency-controlled chocolate pump to feed the product to the unit, equipped with a rotating plate assembly on a main shaft driven by the main shaft motor. These plates are housed in independent double-jacketed compartments, through which cooling water is supplied in a controlled and constant flow. A thin layer of chocolate circulates between the plates and the compartment. Since the XPTC-50 is divided into different zones and the temperature of each is exhaustively controlled, cold is rapidly transferred to the chocolate, causing the formation of beta crystals and its tempering. The same product circulations carry the chocolate to the point of consumption, while unused chocolate returns to a previous hopper. This last section includes the detempering unit to destroy crystals, thereby allowing the reuse of chocolate without damaging it.

The design of the rotating plates ensures that all chocolate particles
follow the same path.

Four zones with independent temperatures

The machine’s design ensures that all chocolate particles follow the same path, meaning the entire mass is treated uniformly, thus avoiding the risk of over-tempering or insufficient tempering. The precision of the treatment is guaranteed by temperature controls divided into four independent areas, the last of which extends all the way to the point of consumption.

Modern. Versatile

Operational advantages

Compact and easily accessible design facilitates installation.
Flow regulation allows control of tempering time.
Quick maintenance and cleaning due to its accessibility.
Low energy consumption and high operational reliability.
The use of a single water circuit for each zone, for both cooling (working position) and heating (stand-by position), facilitates control and maintenance, while reducing equipment preparation times for start-up.
