DIC is a HTST (High Temperature Short Time) treatment. This thermal effect if doubled by a mechanical effect, which is the pressure effect.
These actions, developed at regulated levels and defined steps bring the product to structural changes
These changes are responsible for all the applications of the DIC process: decontaminating, swelling, steaming, essential oils extraction etc.
DIC....How does it work? Bio Essential Sdn. Bhd. DIC Dried apple after DIC treatment Dried apple before DIC treatment Pictures from a scanning electron microscope
Principle Bio Essential Sdn. Bhd. P : Processing pressure / P 0 : Atmospheric pressure / P v : Vacuum pressure Figure 1 Variation of pressure during one DIC processing cycle
Phase 1: A vacuum is first created within the reactor by opening the discharge valve. This step will promote optimal transfer of heat between the steam and the product .
Phase 2: The discharge valve is closed and saturated steam injected to create a pressurised atmosphere. It involves an increase of temperature and pressure.
Phase 3: High pressure is maintained for a short time .
Phase 4: Opening of the discharge valve creates a sudden pressure drop inside the reactor due to the vacuum. This pressure drop induces concomitantly a partial auto-vaporisation of the water contained in the product and the expansion.
Phase 5: The discharge valve is then closed and atmospheric valve opened to allow a return to atmospheric pressure within the reactor and the sample is recovered .

Bio Essential Sdn. Bhd. DIC Technology in the operations of Pretreatment of Extraction & Extraction
Products description -Pretreatment for extraction industry- DIC pretreatment improves your classical extraction yield
Classical HAV (high added value) molecules extraction are faced to the following problem:
Current extraction methods are able to extract available amount of HAV molecules
This extracted amount is only the visible part of the iceberg…
The major part is trapped within strong cellular structure
Yields are limited by such limited availability
We developed a method to make HAV molecules more available, to dramatically increase the extraction yields
