Advanced Cryogenic Solutions by Dohmeyer

The Dohmeyer injector is a high capacity, close control device, it can be used with either liquid nitrogen or liquid CO2 and is able to be fitted to any paddle or ribbon mixer. The injector is IP69K rated, featuring a non return plunger that prevents contamination. The unit can be opened without tools for easy cleaning and maintenance.

The Dohmeyer cryo cabinet has a small footprint and is easily integrated into your batch production process. Providing you high throughput with minimal capital investment. The cabinet has a hygienic design that allows easy cleaning and avoids bacteriological traps by having no sharp corners or internal threads.

The Combo Chiller offers an efficient, fully automated chilling process using economical liquid CO₂ instead of dry ice. It ensures improved meat quality through uniform cooling, while enhancing, reducing manual handling, and providing precise CO₂ control and temperature monitoring throughout the process.

With our LIN Crown Hardening Unit, you can stabilize decorations in your cone, cup, or swirl ice cream. Our solution ensures the shape is maintained even with demanding sauces or sprinkles. The unit is compatible with all ice cream fillers. Constant access to liquid-phase nitrogen only—without gas bubbles—and a specially designed injection system provide total process control and a wide range of possibilities.

CryoRoll is a cryogenic freezer designed for high-performance IQF freezing of small pieces of meat, cheese, pizza toppings and fruits. It uses a rotating drum where the product is injected with cryogenic gas (liquid nitrogen or CO₂ snow). The system achieves extremely low temperatures—down to -60°C with CO₂ and -110°C or lower with nitrogen—ensuring a high temperature gradient, rapid thermal exchange for efficient and uniform freezing.

The Dohmeyer Fat Glaze Crystallization Unit is specifically developed for the ice cream industry. It is designed to be integrated in-line with the production equipment to improve fat glaze distribution and rapidly solidify it between the ice cream and the sugar cone. As a nitrogen based technology, it ensures a smoother and more protective chocolate layer in a very short time.

The Liquid Nitrogen immersion bath is used to coat a layer of water-fruit based juice on an ice cream substrate. This equipment works in combination with an ice cream filler line. The Liquid nitrogen immersion bath can also be used for rapid freezing of biomedical materials, or pharmaceutical products and many other applications.

The Cryo Mixers series is the highest-quality open mixer line with parallel paddle shafts. It has a diverse product range with a tailored configurations and a variety of accessories. Select one and adjusted to your production needs.

The Multibelt Freezer is a tunnel designed to achieve IQF (Individually Quick Frozen) product. As the product falls from one belt to another, it rotates and separates, allowing for perfectly even freezing of each individual piece. The compact design ensures a small footprint while maintaining maximum throughput. Additionally the side ventilation enhances freezing efficiency at the lower levels.

The Nitrogen Stamp Unit uses a controlled application of liquid nitrogen onto a sintered metal substrate, creating a thin insulating vapor layer. This enables nitrogen droplets to hover over the surface without direct contact, preventing rapid boiling, thus ensuring a clean, repellent and residue-free process.

The Dohmeyer Pelletizer instantly freezes droplets of enzymes or bacterial cultures using liquid nitrogen at –196°C, forming uniform cryo-pellets. It preserves bioactivity, ensures precise dosing and supports applications in dairy, bakery, brewing, pharma, and research. Ideal for small to large-scale production, it offers clean, reliable and scalable cryogenic pelletizing.

The CSF has a compact flexible design that can be customized to suit your process. The paddles within the injection zone are manufactured to suit the product and can be used with either LCO₂ or LN₂.. The injectors are fed through a vacuum insulated line with integrated safety valves, guaranteeing instant and close controlled cooling that can be oriented for top or bottom injection. The screw itself is fully removable for cleaning, it comes fitted with rotation detection, coded sensors and boundary temperature control.

The Snowhorn is perfect for cooling down big volumes of product in almost every step of the production process. Due to the expansion of the CO2 gas used, the Snowhorn also creates an oxygen-free environment, which prevents oxidation of the processed products. Besides the anti-oxidation, the CO₂ gas also creates a bacteriostatic atmosphere in closed spaces, further improving the quality and prolonging the shelf life of the final product.

The Cryo Spiral freezers are advanced machines used for rapidly freezing food products using liquid nitrogen or carbon dioxide. By reaching extremely low temperatures, they enable quick freezing, which preserves the texture, taste, and nutritional value of the products. They are energy-efficient, utilize space effectively and can freeze a wide range of products, including fruits, vegetables, meat, fish, and ready meals. The spiral design allows for high throughput in a compact footprint, offering high-quality freezing.

The Trideck is a three-belt tunnel designed to achieve IQF (Individually Quick Frozen) product. As the product falls from one belt to another, it rotates and separates, allowing for perfectly even freezing of each individual piece. The compact design ensures a small footprint while maintaining maximum throughput. Additionally the side ventilation enhances freezing efficiency at the lower levels.

The Dohmeyer Cryo Tumbler is the perfect solution for your IQF coated product needs. It is available in a wide range of sizes and provides unmatched coating performance, giving an even application of coatings up to 700% weight-wise.

The Dohmeyer Top Lifting Tunnel provides flexibility and efficiency for your production process. It has been designed with class leading hygiene features such as the elimination of seals, that the top lifts along the total length of the tunnel, thus giving easy access for cleaning and that all the internal surfaces are sloped towards the drainage points.

The Dohmeyer Cryo Vertical Freezer is designed for efficient crust freezing of meat products, featuring a dual-zone system for rapid chilling and uniform hardening. Its compact design with a stainless steel chain and basket, ensures durability and seamless integration with slicing lines. Ideal for operations requiring a small footprint and consistent product quality.
