SARAYA's Rapid Freezer

A high-quality freezing technology that changes the conventional concept of "freezing" in
your cooking and distribution. Expand your business with taste as the center of your foods!

Rapid liquid freezing, new possibilities with overwhelmingly freezing speeds

Rapid Freezer is a freezer (alcohol brine freezing) that rapidly freezes food without compromising its quality by immersing the food in a special solution chilled to -30°C. Compared with conventional freezers, freezing times are quicker and food quality loss during freezing is minimised, so that the quality of the food remains the same after thawing as it was before freezing.

Liquids, about 20 times more thermally conductive than gases.

Water in food crystallizes into ice as heat is taken away. Liquids freeze about 20 times faster than gases, making freezing with alcohol solutions result in smaller ice crystals and minimal destruction of cells in the food. This ensures good restoration during thawing and the same quality as before freezing.

Comparison between Rapid Freezer's freezing method vs standard ones.

Freezing speed determines quality. High-precision freezing ads value

Advantage #1

Reducing dripping to avoid deliciousness!

Rapid liquid freezing produces little effect on frozen food, maintaining freshness, taste, texture, and appearance with less dripping. Improve yield while maintaining quality and taste after defrosting, opening up new cooking possibilities.

Advantage #2

Reforming the production process to improve quality and reduce costs!

Bringing seasonal food to the table all year round!

By freezing in bulk foods purchased in season, they can be provided with the same deliciousness all year round.

  • POINTCosts can be reduced by purchasing large quantities when the price is low in the season.
  • POINTBy keeping ingredients fresh just after being caught or harvested, food losses are dramatically reduced.

Prepare and store food when you have time!

Prepare food when you have time and rapidly freeze it to preserve its quality! By preparing food in the low season, you can provide the same quality as freshly prepared food in peak seasons, without hassles or making customers wait.

Freezing time comparison

Food begins to freeze at -1°C and it almost completely frozen at -5°C. If the time required to pass through the maximum ice crystal formation range (the temperature range where ice crystals form) is long, as in slow freezing, the ice crystals will grow larger and destroy the food. The rapid freezing speed of the Rapid Freezer allows passsing through this range quickly, with ice crystals not growing large and remaining small, permitting the food to be frozen without destrying any cells.

Freezing time comparison between Rapid Freezer and standard slow freezing

Reducing lost of nutrients and flavour

With high-quality freezing that does not damage the cells of foods, even foods that would deteriorate in standard slow freezing retain the same freshness, taste, and appearance as before freezing.

Beef freezing experiment

High-quality freezing prevents the damage of the cells of the meat, avoiding the leaking out of flavour and nutrients, in a liquid called purge. Purge refers to the loss of water in meat, a "meat juice" that also carries a lost in proteins and vitamins that give juiciness and nutrition to the meat. By performing high-quality freezing and storage, with thawing methods that suit the ingredients, we can reproduce the same freshness and quality as before freezing.

Beef frozen with Rapid Freezer
Rapid freezing (Rapid Freezer)
With rapid freezing, it has a fine texture even after thawing, keeping the same level of quality as before freezing.
Beef frozen with slow freezing
Slow freezing (standard air blast freezer)
With slow freezing, purging of the meat occurs after thawing, and the beef curls up.

Tuna freezing experiment

Rapid freezing (Rapid Freezer)
Even after thawing, purge does not flow out and the meat stays tight.
Tuna frozen with slow freezing
Slow freezing (standard air blast freezer)
Slow freezing has purge leaking out after thawing.

Konjac jelly freezing experiment

Rapid freezing (Rapid Freezer)
Rapid freezing keeps the texture fine and smooth.

Slow freezing (standard air blast freezer)
Slow freezing leaves the surface uneven and leaves a coarse texture on the tongue.

New foods and distribution with a new freezing technology

Use of high-quality freezing technology maintains the quality of products for a long time, reducing food loss. Freezing also enables long-distance transport, opening up new markets.

Product features

Rapid Freezer is a liquid quick-freezer that freezes packed foods by dipping them into -30°C antifreeze that can efficiently freeze everything, from vegetables and fruits* to meat and fish, as well as side dishes.
*Vegetables and fruits, when frozen, can't return to their original fresh state. In these cases, conservation as a processed food is recommended.

Rapid Freezer Dedicated Liquid Drainer Stand

Draining Stand

Rapid Freezer Dedicated Liquid Draining Stand

Liquid Draining Stand exclusively for Rapid Freezer. When removing frozen foods from the cooling tank, they can be used to drain the alcohol solution from the exteriors of bags, to then return it to the tank. They not only improve workability but are also economical, as they reduce the amount of alcohol solution removed from the immersion tank. No tools needed for attachment.

Use the Drainer stand to avoid any lost of freezing liquid when removing foods from the Rapid Freezer.
