Available in a variety of sizes, they feature a welded stainless steel tank, double lid with thermal and acoustic insulation, thermostatically controlled indirect heating
in the side walls, and an electronic control with digital time / temperature display.
Without this indirect heating
, thermally sensitive food products, such as these amino acids cannot be dried without oxidation or the risk of thermal damage and loss of nutritional value.
Via an indirect heating
process (to a temperature between 350 and 375 degrees), PPD products are delivered in a dry mix biodegradable bag that is specifically measured to be effective in all weather conditions.
There are a number applications - most notably where both direct and indirect heating
are required simultaneously - where steam generation is the only viable solution and the technology has advanced dramatically to keep pace with changing requirements.
A calciner is defined as equipment that removes chemically bound water or gases from minerals through direct or indirect heating
; a dryer removes free water from minerals through direct or indirect heating
An indirect heating
element located beneath the bath and an integral drain make cleaning even easier.
Chris Horsley, Managing Director of Babcock Wanson UK, explains: "we were introduced to 2K in 2007 and worked together to develop an indirect heating

The Bulkflow heat exchanger is offered for indirect heating
and cooling of free flowing bulk solids.
Their gasification process works through an indirect heating
process that involves no combustion of the waste feed stock.
Plasmin survives the direct and indirect heating
of pasteurization and UHT processes.
According to Hosokawa Bepex, this method has proven to be superior to either pneumatic or mechanical agitation using direct or indirect heating
, since both these methods permit agglomeration or pellet deformation.
