DSI Platematic Samifi Freezers
In-line freezing of packaged products Platematic utilizes the principle of double contact freezing. This is the most rational and effective method for food freezing and guarantees the highest quality of preserved products at the lowest running cost. Direct contact between evaporating plates and product, coupled with automatic loading and unloading operations, make PLATEMATIC a compact and simple unit that can be installed in any processing line.
Automatic adjustment of both plate opening and in-feed movement according to product size, self adjusting in-feed level, as well as a wide range of accessories, provide most flexible, automatic plate freezing operation today. Platematic freezer is recommended for in-line freezing of packaged fish, meat or vegetables, pre-cooked meals in cartons, alu-trays or bags, and types of products in packages and bulk product in trays.

DSI Pressmatic Freezers
Freezing and Pressing
Products like fish fillet and surimi need to be frozen in blocks of uniform density, perfectly leveled, with precise shape, size and weight tolerances. This requires a machine to freeze and compress product at the same time. Therefore handling of freezing trays is generally accomplished manually and by batch, an operation that is labor intensive, takes considerable space and adds the inconveniences of discontinuous production.
Fully Automatic
To better this kind of procedure, DSI Samifi has introduced PRESSMATIC, the first Automatic Plate Freezer that combines freezing and compressing with continuous in-line operation.
How it works
PRESSMATIC operations are based on the experience gained by DSI Samifi freezers with hundreds of Automatic Plate Freezers installed throughout the world for over 30 years. The freezing frames come along a conveyor belt and are automatically loaded into the freezer, row by row. Once a station is completed, an exclusive hydraulic system closes the plates and applies uniform pressuer over the product. Then it starts charging the next station ans so on, until the freezer is filled. During this process pressure is constantly maintined on all plates. Thereafter the PRESSMATIC returns to first station and continues to load/unload the product row by row, on the basis of "first in, first out".
Advantages
- Continuous in-line operation: Immediate and combined actions of freezing and pressing eliminate dripping and weight loss. The compact arrangement and the "through feed" feature are ideal for continuos production lines.
- Top quality product: The pressure guarantees flat, uniformly sized blocks.
- No labour required: In-feed and out-feed of frames are completely automatic.
- Space saving: A PRESSMATIC installation is considerably smaller that a manual batch system with same capacity.
- Versatility: PRESSMATIC units are available in both Marine and Land versions for capacity up to 60 tons a day.
Features
- Automatic predetermined counter pressure: Guaranteed by the unique hydraulic and mechanical system.
- Multi-purpose loading device: Patented, to automatically provide the following functions. Normal loading and unloading of the frames, emptying the whole freezer, drying all plates after defrosting.
- Heavy-duty 50 mm freezing plates: Designed for maximum mechanical strength as well as efficient refigerant flow.
- Heavy-duty steel framework: Hot dip galvanized and protected with stainless steel in the areas subject to friction.
- Robust insulated cabin: Entirely lined with stainless steel, with inspection doors or motorized roller curtains (marine version).
- PLC control: All functions of the freezer are electronically controlled according to the selected program.
- On Board Installation: The Marine version is available with specific accessories for on board installation to guarantee smooth operation even in heavy sea conditions.
