Induction Drum Heater Application: Cosmetics

LMK Thermosafe drum heater solution: 

A major manufacturer of cosmetic, aromatherapy and toiletry products opts for Thermosafe and ferritic stainless steel 200 litre vessels for many of its batch mixing and heating requirements.

Due to the customer's wide range of products and frequent trial developments, having flexibility in their manufacturing process was essential.
Melting of coconut fatty acid from drums had to be done with relative ease.

Easy access to the drum, hazardous area certification, and effective temperature control, led the customer to implement Thermosafe as an effective basis for their drum heated and stirred reactor systems.

This application of drum heaters for the cosmetics industry often involves adding a range of fragrances, for example in the manufacture of shaving cream. The shaving cream is manufactured odour-free. Later, batches of up to 200 litres are heated in a stainless steel vessel, prior to adding the different fragrances and homogenising.

With total encapsulation of all electrical components, the thermosafe heater stays much cooler than the drum it heats. It can also be hosed down for cleaning, and is not susceptible to damage from spillage. One can therefore leave it unattended to, with control if necessary, even overnight.

The Thermosafe units can also be used to dry plastic containers after cleaning, and prior to refilling. The plastic containers are placed within an open top 205 litre mild steel drum. With the lid in position, the drum acts like a "mini-oven". Drum wall temperatures will reach 100°C within approximately six minutes, and reach a maximum of 123°C (at 20°C ambient).

This method is suitable for heating materials in small containers, both metal and plastic. Mild steel containers will additionally receive induced energy directly from the heater, and will therefore be heated by two means.

Another option is to part fill the 205 litre drum with liquid (usually water), and use it as a hazardous area "water bath", with the smaller containers being immersed in the liquid.
