What is horizontal plate freezer?
The horizontal contact plate freezer is ideal for block freezing. and preserving portioned products. The products are placed into trays or freezing frames and these are slid between the freezing plates. Frozen blocks, flat and uniform, are easily stacked and stored.
What is contact plate freezer?
Contact plate freezer can quickly freeze products by moving up and down the inside aluminum plates so that the products exchange heat with two plates. Refrigeration system can be equipped as per different requirement of users.
How does a plate freezer work?
Plate freezers are commonly used for freezing brick-shaped packaged products. In plate freezers, refrigerant is allowed to circulate inside thin channels within the plates. The packaged products are firmly pressed between the plates. High rates of heat transfer can be obtained between the packaged product…
What is required temperature for contact plate freezer?
-40 degrees Celsius
Plate freezers operate at a temperature of -40 degrees Celsius that ensure a plate temperature of -34 degrees Celsius. Block temperatures reach -18 degrees Celsius. The freezing time for food blocks to reach a core temperature of -18 degrees Celsius is approximately 105 to 120 minutes.
What is a cold plate freezer?
A cold plate (also called a holdover plate) is a large tank inside your refrigerator or freezer box filled with a solution that freezes and melts out at a temperature lower than water (20 degrees for a refrigerator, -10 degrees for a freezer). The energy stored in cold plates then provides cooling for 24 hours or more.
What is block freezing?
Block freezing is a process of pushing cold air at high velocity across the product to reduce the temperature down to -18°C as quickly as possible.
What is plate contact systems?
It is an indirect freezing system in which the food product does not have any direct contact with the medium used for the product temperature. The basic system of plate freezers consists of flat hollow plates, refrigeration coil these plates to cool the surface in contact with the food products.
What are cryogenic freezers?
Cryogenic freezers use liquid nitrogen or liquid carbon dioxide as the refrigeration medium, and the freezers may be batch cabinets, straight-belt freezers, spiral conveyors, or liquid immersion freezers. The most common type of cryogenic freezer is a straight-through, single-belt tunnel.
Can you put plate in freezer?
The short answer is yes—but there are a few rules you should follow. When using Pyrex or any glass bakeware or cookware, you should avoid extreme temperature changes—very cold dishes shouldn’t be placed in a hot oven, and vice versa. Sudden changes in temperature may cause the dishes to shatter or break.
What is air blast freeze?
Air blast freezing is the process of taking a product at a temperature (usually chilled but sometimes at ambient temperature) and freezing it rapidly, between 12 and 48 h, to its desired storage temperature which varies from product to product (e.g. fish = −20 °C, beef = −18 °C).
How does ice cream cold plate work?
The liquid refrigerant then goes through a capillary tube which drops the pressure and temperature of the liquid. This low temp liquid refrigerant then enters the cold pan’s cooling coils, where heat is absorbed by the refrigerant travelling through the tubes. This is what cools the ice cream pan’s surface.
What are cold plates?
Cold plates are typically made from metal, with flow paths machined into them for a heat-transfer fluid to flow through. As the plates absorb electrical waste heat, they dissipate it through the flow paths using liquid cooling.
What is a double contact plate freezer?
The double contact plate freezer is a fast and economical way of freezing based on double contact with the product packaging. In addition, this method of fast, low-temperature freezing maintains the natural quality of the product.
What is a horizontal plate freezer?
The horizontal plate freezer consists of a number of horizontal evaporator plates, through which a cold refrigerant circulates. The products are placed in trays or boxes between the open plates, which are then closed to provide rapid double contact freezing.
