A revolutionary installation for blast freezing and storage
The HEIN MODULUX² cabinet is a recently developed concept for blast freezing and storage of doughs and pastries, meeting all requirements. This installation features a modular construction that can be modified and expanded at will.
It is based on a blast freezer module to which up to five frozen storage modules can be adapted on the right side. Additionally, the installation can be completed on the left side with one to two refrigerated storage modules.
This installation offers the best cooling conditions for an efficient freezing process and optimal climatic storage conditions, providing the conditions needed to achieve the best dough and pastry quality.
The HEIN MODULUX² range was awarded the DBZ IBA Trophy for its innovative PID regulation.

Operating principle
Rapidly reaching and surpassing the core temperature of -7°C with minimum moisture removal constitutes the decisive condition which, combined with maximised climatic storage, ensures excellent product quality.
The temperature of the blast freezer, which forms the base of the installation, is adjustable in the range of -8°C to -36°C. Efficient freezing of products takes place within this range. The theoretical freezing capacity allows 50 kg of fresh dough pieces (60 g individually) to go from +26°C to -7°C in just 45 minutes.
After the freezing phase, products are placed in the storage section, where the temperature can be regulated in the range of -8°C to -22°C.
The compressor should ideally be installed outside the bakehouse. This avoids noise and heat disturbance in the production area. Fresh air supply to the compressor considerably reduces operating costs and significantly increases the service life of the refrigeration system.
The installation is equipped with a fully automatic defrosting unit. The evaporator is integrated in the blast freezer section. During the defrosting process, heat emission towards the storage section is blocked, thus neutralising any unwanted heat influence on the stored products.
Construction, materials and quality criteria
The HEIN MODULUX² cabinets are of modular construction. The blast freezer is the main module, equipped with the compressor and computer control. On this "base station", up to 5 frozen storage modules and up to 2 refrigerated storage modules can be mounted, each designed for 2×15 trays (600×800 mm).
The hatches as well as all cladding and floors are made of stainless steel. There is no interior plastic lining. They are fitted with easy-to-clean hatch closures, hinges with end stops, double sealing profiles with frame heating and easily replaceable sealing strips.
This optimises daily use and ensures the installation an unrivalled service life, even under intensive use.
Each module is equipped with 2×15 pairs of angular supports that can be varied per pair at a distance of 25 mm. The HEIN MODULUX² units stand on extremely stable and adjustable feet, also made of stainless steel.
Minimum height: 2080 mm — Maximum height: 2180 mm.
