Special packages, dual-chamber carpules or dual-chamber syringes are trans- ported. worldwide, patents for this innovative technology are held by HOF.
AnD PrODUCeD in germAny the loading and unloading systems are installed and tested in our own production area in combination with the freeze dryer or a specific equivalent dummy. All set- tings and functions can be tested extensively. this has the advantage that the in- stallation and testing times are shorter at our customers site. it is possible to upgrade existing freeze-driers with HOF loading and unloading sys- tems and therefore to meet customer requirements. Depending on the requirement it is possible to couple a freeze-drying plant and loading and unloading system with isolator or rAbS technology.

A constructive technology based on natural refrigerants has been developed and has been already successfully implemented over the past years. One natural refrigerant alone cannot reach the required temperatures, for this rea- son HOF implements a two-stage refrigeration system (cascade). this system uses the halogen-free refrigerant r170 in a cryogenic temperature circuit and r1270 in a high-temperature circuit providing a larger energy spectrum. in addition to the cooling circuit of the chamber, a cooling circuit for the condenser is installed in a modular design. this enables a spatial separation of the freeze dry- ing plant and the refrigeration system with hydrocarbon.
tHiS HAS 3 ADVAntAgeS: the encased refrigeration systems can be disposed in a flexible way indoors and outdoors. The aTeX-requirements only apply within the encased refrigeration system. Freeze drying plants with multiple refrigeration systems secure the process. in case of failure at one of the refrigeration systems, the second refrigeration system is sufficient to secure the product. This pioneering refrigeration technology can be used for new freeze drying equipment as well as in retrofitting of existing plants. enerGy-eFFicienT TranSporT oF deep cooled diaTHermic liquidS For decentrally installed freeze-drying systems, there are ener- gy losses arising from increased heat intakes for storage and transport. in response to this specific requirement, HoF has developed an innovative and high-efficient heat-transfer me- dium pipe installation. This unique solution focuses on high vacuum isolated double pipes with a nominal diameter up to dn100. The pipelines are manufactured at HoF and are then installed at the customers site. This new technology currently offers the best possible long-term insulation and sets new standards on the market. proceSS deVelopmenT in THe laBoraTory in mornSHauSen Safe and stable freeze-drying processes are essentials in the production chain of our customers. For this reason, HoF has been offering a valuable support in process development and process optimization for many years now. This service unit is lo- cated in mornshausen in our pilot-plant technical laboratory. The pilot plant laboratory, equipped with modern appliances such as a HoF minilyo with radiation separator, a cryomicro- scope and excellent resistance and temperature measuring de- vices, optimizes the drying processes at the highest stage. Furthermore, the HoF massanalyzer enables the analysis of mass spectra, in particular traces of silicone oil, and the moni- toring of water vapor concentrations in the process atmos- phere under vacuum.

The com- pany owner and hobby farmer Hans-Georg Hof is a pioneer in concluding the entire value chain by working straw into com- bustible to generate its own heating energy. The straw is a byproduct resulting from the cultivation of grain is worked into straw pellets during a complicated procedure in the own pellet plant. The pellets are then burned in the spe- cial biomass boiler for co2 neutral heat production. The ash obtained during the burning process is then further of use as an excellent fertilizer for the family’s agricultural areas.
