TCF Sales offers a variety of batch tempering machines and solutions to temper your chocolate. Batch tempering systems are popular for tempering single batches of tempered chocolate and for controlling the quantity of ingredients added to each batch. Automatic batch tempering machines have on-board cooling systems that take the chocolate through the tempering curve to crystalize it, using refrigerant gas with a compressor or water through a water jacket. Chocolate is tempered in a "batch" based on the tank size. Another key feature of batch tempering machines is that they can be cleaned relatively easy with hot water and can easily accommodate the change-over of one chocolate to another.
