Industrial drying machines are designed to remove moisture from your product. But the drying process must cater to variations in the state of matter and molecular structure of the input material. Industrial dryer technology exploits the modes of heat transfer (convection, conduction, radiation, evaporative cooling) to control the moisture content.

What’s the only living connection between our present world and the age of dinosaurs? The ginkgo biloba plant. Also known as the maidenhair tree, it is regarded as a living fossil and has been around for more than 200 million years. Ancient civilizations in China were already mastering ginkgo processing centuries ago and the tradition soon flourished around the world.

Freeze drying is the most gentle and aroma protective method of drying, widely used in the coffee industry, but also with applications in the food industry and pharmaceutical sector. Specialist continuous freeze drying plants are bespoke designed to meet your exact requirements and deliver a superior end product.
<h2>Continuous belt freeze dryer for gentle handling of delicate product</h2>
The Devex continuous vacuum belt freeze dryer is the ideal solution for continuous freeze drying of granulates. It allows gentle batch feeding and discharge via vacuum sluices to preserve product quality and minimize mechanical handling - perfect for delicate products where maximum retention of aroma, taste and colour is vital such as coffee products, pharmaceuticals, fruits and herbs.

A bespoke Devex freeze drying plant can handle the full product cycle: foaming, freezing, granulation, sieving, sublimation inside the belt dryer, ice condensation, heating system and high-vacuum technology.

Plant extracts are vital to functional food preparations. But drying them into solid granules may destabilize their thermolabile compounds and degrade flavors and nutrients. The heat generated by drying solutions poses a risk to the quality of extracted substances.


<h2>Protect heat-sensitive compounds with a gentle dryer</h2>
The DryCab by Bucher Merk adapts vacuum drying for heat-sensitive food ingredients such as plant extracts. Its low-pressure technology applies vacuum from a minimum of 0.5 mbar, shielding compounds from over-exposure. The evaporation capacity ranges from 0.5 kg/h to 250 kg/to adjust to different plant materials.

With a working batch volume rate between 2.5 and 2,500 liters, the vacuum drying cabinet is available from lab-scale to industrial solutions. Its heating plates are designed to reduce dead space and hold an active heating surface up to 88m2.

Organic volatile compounds from fruits, vegetables and herbs are essential to manufacturing flavors, extracts, and pure powders. But elevating temperatures during the evaporation process risks altering their chemical structure and lowering the quality of the final product.


<h2>Gentle freeze-drying for fruit powders, herbal extracts, and flavors</h2>
The DryBand system by Bucher Merk is a dynamic belt dryer designed to dry delicate food ingredients. The material moves through an intermediate vacuum chamber between the top and bottom belt section. The drying unit has a vacuum range of 0.5 to 50 mbar and a feeding rate of up to 4,000 kg/h.

The continuous system can be configured for variable or constant drying with heating plates underneath the belt. A crushing device at the discharge end breaks the dried products into powders after drying. Meanwhile, the vapors are collected in an integrated condenser.
