How to Choose a Refrigerated Walk-in Cold Storage Warehouse?

Refrigerated Warehouse Types & How to Select

1. Cold Storage Warehouse Types Based on Refrigerating Temperature Range

High temperature walk-in cooler cold storage warehouse - Class L, Temperature Range: +5℃~ -5℃. The storage purpose of this refrigerator cold room is for refrigerated storage of food like vegetable, fruit, egg, pharmaceutical material, floral, wood and other things suitable for this temperature range.

Medium temperature walk-in freezer cold storage warehouse - Class D, Temperature Range: -10℃~ -18℃. The storage purpose of this freezer cold room is for frozen storage of food like meat, seafood and other things suitable for this temperature range.

Low temperature walk-in freezer cold storage warehouse - Class J, Temperature Range: -23℃~ -28℃. The storage purpose of this deep freezer cold room is for the frozen storage of ice cream and other deep frozen food etc.

Ultra low temperature walk-in freezer cold storage warehouse - Temperature Range: ≤-30℃. The storage purpose of this ultra low temperature cold room is mainly for fast frozen food, industrial laboratory test room, medical treatment, blood bank, etc.

To design a cold storage plant, besides considering the size of the cold storage warehouse, the important thing you need to consider for a refrigerated warehousing project is to select the suitable refrigeration temperature of the refrigerated warehouse. The temperature of the cold room plant shall not be too high or too low.

2. Cold Storage Warehouse Types Based on Installation Structure:

Civil construction refrigerated warehouse - The space enclosing structure wall material of the cold store room is made of brick and the heat insulation material is made of sprayed polyurethane (PU foam).

Assembling refrigerated warehouse - The space enclosing structure wall material of the cold store room is made of prefabrication modular cold room insulated panel (insulated foam panel). The foamed insulation material of the cold room panel is polyurethane (PU panel).

To build a civil construction refrigerated warehouse or assembling refrigerated warehouse, you need to consider your local building construction and local building cost on the refrigerated warehousing storage project. We prefer to build a assembling refrigerated warehouse because the prefabricated modular cold room panel (insulated sandwich PU foam panel) can be installed and disassembled at any time and it is very convenient to move the cold storage warehouse to another installation place.

Refrigerated Storage Requirements of Food and Physical Nature

Before you decide to design and build a walk-in cooler or walk-in freezer cold storage warehouse, you need to first know what is the best storage temperature of the cold room plant to store your food material or other materials. In this way, you can avoid to build a refrigerated warehouse which is not cool enough to store goods or is too freezing and to freeze & destroy the food and waste investment money on cold storage plant project cost because the colder temperature requires bigger powerful compressor and refrigeration system.

Food Name	Refrigerating Temperature （℃）	Relative Humidity （%）	Storage Period（Month）	Freezing Point （℃）	Specific Heat（KJ/Kg.℃)		Latent Heat （KJ/Kg）	Storage Capacity （m³/t）
Food Name	Refrigerating Temperature （℃）	Relative Humidity （%）	Storage Period（Month）	Freezing Point （℃）	Above Frozen Point	Below Frozen Point	Latent Heat （KJ/Kg）	Storage Capacity （m³/t）
Apple	-1~1+1	85~95	（2~7）	-2	3.85	2.09	218	7.5

Frozen Mutton	-12~-18	80~85	(3~8)					6.2
Frozen Egg	-18		(12)
Sausage	-4~+5	85~90	7~21
Milk Oil	0~+2	80	7					7.5
Sugar	+7~+10	<60	(12~36)	0.2	0.84	1.67
Rice	+1.5	65	(6)	-1.7	1.09
Beer	0~+5		(6)	-2	3.77	1.88	301	10.6

The above form shows the best suitable temperature for the refrigerating storage of different food materials of fruit, vegetable, meat, drink beverage etc.. So you can take the listed temperature range as reference to design and build your walk-in cold storage warehouse and refrigerated warehouse for your restaurant, hotel kitchen, supermarket, chain store, vegetable & fruit market and other cold storage logistics plant.
