DSI, a Danish manufacturer of automatic and manually operated freezers for onshore and marine applications, showcased its new Horizontal Plate Freezer model at the Brussels Seafood Expo 2014. The redesigned product offers instant freezing capability and is made with a galvanised steel frame and hydraulic rams that ensure stable and even plate pressure. + VIDEO

The new DSI HS Plate Freezer using natural refrigerant ammonia (R717) is designed to work either as a stand-alone unit and be manually loaded and unloaded, or integrated in a process line for packed products in trays or cartons, with automated loading or unloading.

Fast and efficient double contact plate freezing

Double contact with the product packaging makes for cost efficient and rapid freezing; furthermore, the fast low temperature freezing maintains product quality, appearance and freshness. Hydraulic cylinders maintain a stable and even plate pressure on the product during the entire freezing phase.

New design– single station opening for continuous, uniform, rapid freezing

The new plate freezer design enables continuous freezing in uniform blocks, thanks to only one station being open while loading and unloading, so as to optimise energy efficiency.

The plate freezer is made with a heavy-duty hotdip galvanised steel frame, easy to maintain and clean. The particular surface structure prevents dents and marks in the product packaging.

Mads Sigsgaard, Regional Sales Manager for DSI, comments:

The first installations of the Horizontal Process Freezer are operating very well and to the satisfaction of the customers. With the production experience gained over the last year we have further improved the freezers with a more simple and safer opening system, maintaining the benefits of freezing the product directly from the production line. This ensures that the quality of the frozen products is the best possible.”
