The Basics

  1. Fill water jacket with demineralised water – demineralised water is low cost and is purchased from supermarkets and hardware stores for around $4 for 5 litres, once filled is left in the unit and just topped up as required, demineralised water has no harmful minerals that tap or tank water contain and will protect internal components.
  2. Heat water jacket to desired temperature.
  3. Add product and heat to required temperature.
  4. Stir occasionally to stabilise product temperature.
  5. Make Products.

Units will have some marks from the manufacturing processes.

Note: High Viscosity Products:

If your intention is to make product that are quite viscos and set quickly we recommend model 7R or 7DR, please contact us prior to purchasing if you would like any product advice, in some cases an electric heat gun is used to warm the tap slightly before pouring for products that set quickly.

Design Capability

Water boils at 100℃, however it is not possible to achieve 100℃ product temperature with double boilers, the main reasons for this are ambient (room) temperature fighting to cool the unit body and heat loss from transference through the wall of the internal product chamber, for these reasons we recommend the units for products up to 85℃, it is possible to achieve up to 90℃ + for product temperature with small manual adjustments at the final heating stage.

Double Boiling Method explained

An electric double boiler means the unit has a water jacket around the outside of the product chamber providing a much larger heating surface, the water jacket protects the product from high heat that is produced by the electric element when it’s heating, the water jacket thermostat controls the heating process, the heated water in the jacket melts/heats/emulsifies/separates depending on the product being used from the base and the sides safely to the desired temperature.

The product tap passes through the water jacket and is surrounded by hot water heating it.

Product is stirred periodically to stabilise temperature before pouring.

Product temperature is maintained by the water jacket thermostat allowing the user to spend time preparing for the final product.
