Food and pet food are delicate goods requiring optimum processing. Product integrity and safety have top priority in the drying process.
Our integrated heat pump system with its constant process parameters ensures reliable drying while low temperatures warrant gentle drying of your products. The closed system produces good results in terms of appearance, aroma and bioactivity.
The heat pump based condensation drying technology implemented in our AIRGENEX®food dryer is the optimum answer to your drying needs.
On the following pages, you may find advantages of our food dryers, how they work and where they are applied.
Heat pump based condensation drying is capable of drying your products at temperatures variable between 20 °C and 75 °C. Temperatures up to 100 °C may be selected. Using low temperatures is a gentle way of drying your food. Drying is absolutely stress-free for your product.
Reliable and Efficient
AIRGENEX®food dryers ensure high efficiency of the drying process. Heat pump technology is used for air dehumidification. The drying operation is reliable and stabilizes your production process, thus contributing to optimizing the process.
HARTER drying systems are basically closed – no interchange with ambient air and, thus, no dependence from the climate. This helps to achieve positive results in terms of bioactivity, aromas and appearance. Sulphurization or addition of ascorbic acid to retain colour, for example, is not required. The dried products do not require any additional flavouring.
Projects realized so far have shown that the condensates obtained may contain volatile aromas and flavours. Harter’s condensation drying always puts you in a position to recycle the valuable condensate or its ingredients.
Less time, less energy
Compared with exhaust air dryers and conventional fan-based systems, our AIRGENEX®food dryers require much less time for drying, which is, of course, dependent upon the drying temperature and the texture of the product to be dried. This is achieved by using the alternative physical approach of heat pump based condensation drying. Optimum air conditioning and air routeing ensure energy and, thus, cost savings.
Combining Drying and Cooling
Our dryers may be easily modified for additional cooling if desired or required by the process. Quite a few combined drying-cooling systems are already in operation. We will also be happy to elaborate energy efficiency concepts, for example to return waste energy from cooling into other processes in your company.
Always the Suitable Drying Solution
Many years of experience in and know-how of many hundreds of drying applications ensure that you get the solutions exactly suiting your product and your production process. This is the only way to success for you, the customer, and us, the supplier.

Fruits & Vegetables
are gently dried at the desired / optimum temperature, which is normally between 35 °C and 65 °C.
are dried at temperatures below 42 °C to preserve vitamins and protein structures. This way, crudités actually remain in an uncooked state – with all its benefits for your special product idea.
We minimise the residual humidity in the relatively dry nuts either to best prepare them for grinding or to enhance their shelf life.
Our gentle drying helps to preserve or condition your germed seeds for further processing.
Gentle drying of bulk material such as seeds is one of our specialties. We do this by drying in a barrel with minimum intermittent movement or by drying in a tray trolley dryer. Our customized air routeing system always ensures uniform drying.
Grasses & Herbs
Our gentle low temperature drying helps to best manufacture your products. Applications are manifold and individual. So are our drying solutions.
Digested Residue & Pomace
Do you need a drying system for a planned up-cycle product? We can help you develop a new valuable product from what seems to be waste material.
Meat & Sausages
Do you wish to create a new snack? Sausage chips, salami chips, ham chips or dried meat, meat chips, beef jerky or any other odd idea – taking us as your technology partner will be a large step towards advancing your plan!
Feed / Pet Food
Are you looking for a low temperature drying system to preserve valuable ingredients in your products? Or do you want to find a system to make your product sterile so that you need higher temperatures? We can offer solutions to meet any challenge!
Drying Systems for Food
We develop, design and manufacture drying systems both for batch and continuous operation. Our technology is modified to meet your specifications. All drying related parameters for your specific application are determined by prior tests in our pilot plant station.
For drying to be successful, a perfect match of air dehumidification and air routeing is required. Extremely dry, unsaturated air, at low temperatures, is routed exactly to the place where humidity is to be absorbed. This process – our heat pump based condensation drying – is applied in various types of system designs. Our drying systems are made of stainless steel and can be cleaned in compliance with applicable food standards. We shall be pleased to meet your specific hygienic design requirements. Just contact us!
Is your application different from above?
You will certainly understand that we cannot possibly list all our drying solutions here. If your application is not covered above, please contact us. We shall be pleased to offer non-committal consultation!
OUR PILOT PLANT STATION – One of our special features.
You want to have your food tested for drying response? Welcome!
You let us know your wishes and requirements, and we will conduct the necessary tests on your products. We will determine and record the parameters relevant for satisfactory drying. Pleasant surprises may be expected as far as aroma, taste, ingredients and appearance is concerned.
You are very welcome to witness these tests and see the results for yourselves.
