Horizontal Plate Freezer Diagram

This paper deals with an experimental analysis of freezing processes using a horizontal plate freezer with co 2 as refrigerant.

Horizontal plate freezer diagram. Dsi automatic horizontal plate freezer with erlinord loading unloading system. The freezers are ergonomically designed to spare the workers and to ensure easy cleaning. Our plate freezers are co 2 operated and extremely energy saving. The co 2 is supplied from an experimental co 2 nh 3 cascade refrigeration system facility with a 9 kw of refrigeration capacity at 50 c.

The experimental facility the data acquisition system and the experimental methodology are described. Today we produce the world s largest horizontal plate freezers. When the plates are arranged in a vertical plane they form a series of bins and in this form they are called vertical plate freezers vpf figure 22. Our hpfs are normally used for the bulk freezing of higher value products fish fillets shrimp roe etc and represent a more space efficient method of freezing than vpf s so are extremely popular on board fishing boats or in smaller space constrained land applications.

The milmeq plate freezer features refrigerant filled plates which make direct contact with cartons of product to provide a rapid energy efficient freeze. For example 45mm thick 2 kg shrimp cartons are hard frozen within 90 minutes using gravity system. An overhead crane system for unloading. Furthermore all our freezers can easily be accompanied by an automatic handling system e g.

As the name suggests plate freezers are composed of an insulated room that holds banks of large horizontal freezing plates positioned within a steel frame. Energy consumption for plate freezing is is generally 25 30 lower than blast freezing. An advanced freezers horizontal plate freezer consists of a number of horizontal plates through which a cold refrigerant runs. Dsi horizontal plate freezers are specially designed to freeze all types of fish seafood meat and poultry vegetables fruits and ready meals in trays.

Plate freezers can be arranged with the plates horizontal to form a series of shelves and as the arrangement suggests they are called horizontal plate freezers hpf figure 2 1. Evaporation temperature within the plate being 40 deg c. Liquid ammonia circulates through the movable plates enabling them to rapidly and efficiently cool cartons of meat by transferring heat by conduction from the product to the evaporator. Our large volume vertical plate freezers are simple to handle and spares time as well as manpower.
