Cold Room and Storage for Flowers

Flowers cold room is designed in a specific manner to keep the temperature and humidity at the appropriate level so that products can be maintained fresh and petals of the flowers stay fresh and good looking. To keep the petals of the flowers fresh and in good condition, air flow is controlled properly.

1, Important aspects for flower cooling and flower cold storage.

(1) Sufficient capacity of the cooling installation to get the flower shipment at the ideal temperature quickly.
(2) A humidity level that is low enough to avoid fungus and diseases, but not so low that the flowers get dehydrated.
(3) A good air distribution: literally around every flower the so-called microclimate should be right. One should therefore not save money on cooling capacity and the size and quantity of coolers.

2, Flower storage room conditions
Temperature control is one of the main factors to assist with long-lasting flowers. Most of the flowers stored at 0-2 °C to avoid danger of more freezing and High Relative Humidity such as 90-95% is recommended for flower in refrigerated storage.

Most of the flowers and greens keep best and longer time if packed dry, without water,in containers which prevent moisture loss and stored at 0-2 °C, we should keep the cut flowers in refrigerated rooms to prevent loss
and should not store flower less than 0 °C to prevent chilling injury.
Most of the flowers re-hydration by using water at 38-43 °C and hold at 4.4 °C, pH is 3.5 is the best for re-hydration for the period of 4-18 hours. Containers should be placed to allow good air conditioning.

3, The best flower cooling: Fast cooling down and keeping cold.
When the flowers come off the field, fast cooling down is crucial. After all, as soon as the stem has been cut, the supply of water and nutrition is stopped and the decay starts. To extend the vase life to a maximum, we want to reduce the metabolism of the flower as quickly as possible. This can be done with vacuum cooling or a pre-cool wall. Vacuum cooling removes the field heat from the flower within 15 minutes, a pre-cool wall takes several hours.

After this step, it would make sense to keep the flowers chilled and hence it would be desirable to grade them (sort and wrap) in a cooled hall or flower chamber. These areas are normally somewhat warmer, as there are people working, but as long as the shifts are not too long this should be fine.
After processing, the flowers are stored in the chilled outgoing cold store until the moment of transport.

The advantages of Atlascool flower cooling
(1) Knowledge and experience in the flower market: we know how to extend the vase life of a flower.
(2) Plenty of experience in flower cooling: continuity and reliability at low cost. References in the floriculture branch: our experience ensures a good result.

The proper cold room temperature is also something that needs to be checked on daily basis.

The monthly cold room maintenance checkups:
The daily maintenance should be done throughout the month.

The efficiency of the system should be checked by carrying out the following practices:

Make sure that the fins of condenser coils are clean.

The evaporator and the fins of the cooler should be clean as well.

Make sure that the room is cooling perfectly when fully loaded.

Ensure that the levels of refrigerants are maintained properly.

The reverse blowing should be working properly as well.

The control valves should function efficiently.

The function of defrosting should work properly because defrosting is imperative to the efficiency of the room.

The evaporators should be clean and functioning efficiently to make sure that the temperature is maintained.

The casing of the evaporator should be cleaned along with the blower fans.

The temperature of the colds room should be calibrated.

To make sure there is no malfunctioning, perform a system functional test.

Doors of the cold rooms:
There are different types of doors for the cold rooms. There can be sliding doors, roller doors and the exit door in the cold storage room. The doors of the cold storage room are usually inspected every two months. The doors are an important part of making sure that the inside temperature of the room is kept constant. The routine checks of the doors include different components like the rollers, brackets, emitters, IR reflectors, control boxes, hinges, alignment of the door and devices used for safety like the door sensor.

Get to know More Blast Freezer Cold Rooms

1, What is a blast freezer cold room?

Blast Freezer room (also called blast freezer, shock freezer) is a kind of cold room with lower storage temperature from  -40°C to -35°C, it is equipped with more thicker doors, PU panels and more powerful condensing units than normal cool room. They typically have multiple shelves where food trays or sheet trays can be stored and freezed at extremely low temperatures.

Blast Freezer room concerns of storing material reliably at consistently low temperature and fast cooling speed, it bring down the temperature and freezing very quickly. They are widely used in the frozen food industry for things like meat, seafood and chicken.

Blast freezing is the process of cooling until obtaining core heat of product with a temperature of -18°C.  This quick-freezing process is conducted in the -35°C / -40°C rooms. When the core heat of the product reached to -18°C, products are transferred to frozen storage rooms. -35°C / -40°C Blast Freezer room is not used for storage purposes; it is only for Blast-Freezing.

Important point for these rooms is that choosing proper cooling device. In order to choosing proper cooling units; product type, amount, entrance temperature, room dimensions and targeted Blast-Freezing time has to be taken into consideration. It is significant to keep Blast-Freezing time short to maintain long self-life of the products. We built plenty of blast freezing rooms taking into consideration minor details of your projects and installed the blast-freezing facilities for quite different industries such as fish, ice cream, red meat, poultry and vegetables.

Cold Storage Room for Fruits and Vegetables

In order to increase the value of fruits and vegetables, we need cold storage rooms to store fruits and vegetables to keep their fresh, there are many factors to affect how fresh produce should be stored. Now let’s learn how to use cold storage room to stock and distribute your fresh products and the most important factors to consider when using cold storage room for fruit and vegetables.

1, Fruits and vegetables must be selected and sorted before entering the cold room storage.

The selection work should be done carefully, it will remove the fruits and vegetables with mechanical injuries, insect injuries or different maturities. Because the fruits and vegetables contain a lot of water and nutrients, it is a good medium for microbiological life. Fruits and vegetables contaminated by microorganisms will soon rot and deteriorate.

While fruits and vegetables of different maturities should not be mixed and preserved. Because more mature fruits and vegetables will rot faster. After selecting those with good quality that can be refrigerated for a long time should be wrapped with paper one by one and packed in boxes or baskets.

The paper used to wrap fruits and vegetables should not be too hard or too thin. It is better to use paper that has been treated with chemicals that do not have any adverse effects on fruits and vegetables. During the whole selection and sorting process, special care should be taken to handle gently to prevent injury to the fruit due to careless work.

2, For Fruits and vegetables cold storage room, we will take a gradual cooling method.

After the fruits and vegetables are harvested, it is better to cool them in the place where the raw materials are produced in time to dissipate the heat inside them. After cooling, the fruits and vegetables are transported to the cold storage room by a refrigerated truck directly. If the fruits and vegetables from the raw materials are not cooled, after entering the cold storage room, a gradual cooling method should be adopted to prevent certain physiological diseases.

For example, some flowers fruits, roots and leaves vegetables must enter the cold storage room as soon as possible for storing. Such as: broccoli, celery, purple camomile, bitter gourd, yam and so on.

Vegetables that generate a lot of heat must be treated with ice water. After the water tank is filled with 0 ° C ice water, all the vegetables are immersed in the ice water to cool the vegetables to 7-8 ° C, and then remove the drained water. Then enter the cold storage room to save. Such as: corn, green beans, stemless beans, rattan, etc.

The vegetables after processing, they must be kept in fresh-keeping bags to prevent the evaporation of moisture when entering the cold storage room.

For leafy vegetables, they must be sprayed with ice water in time before entering the cold storage room.

For other vegetables: the products are sprayed with ice water or covered with a cooling cloth to cool down, and sprayed once every hour during the overnight period Keep the water cool and fresh. Such as: green pepper, eggplant, onion garlic seedlings, tomatoes (immature), potatoes, dumplings, pumpkin, winter melon, yarrow, burdock, etc.

3, Different types of fruits and vegetables should be stored at their optimal temperature.

Produce Type Optimum Temperature °C Optimum humidity % Storage life
Apples -1~+1℃ 85%~90% 3-8 months
Peach -1~+1℃ 85%~90% 1-4 weeks
Grape -1~0℃ 80%~90% 1-2 weeks
Orange 0~+1℃ 85%~90% 8-10 weeks
Grapefruit 0~+10℃ 85%~90% 3-12 months
Pear -0.5~+1.5℃ 85%~90% 1-6 months
Eggs -2~0℃ 80%~85% 5-7 months
Cabbage, spinach, coriander, carrots,kale, celery, lettuce -1~+1℃


90%~95% 1-3 months
Potato +2~+4℃ 85%~90% 1-6 months

Fish and Seafood Industry Cold Storage Room

The fish and seafood cold room is a low temperature room to keep the fresh of all kinds of fish and seafood.

According to the storage time, it can be divided into fresh seafood cold storage room, frozen seafood cold storage room and seafood blast freezer cold room.

Any fresh fish or sea food needs very strict storage requirement as there is a high risk of rapid bacterial growth which can waste the storage. Also it needs to keep separate from all other type of food stored.

1, Fresh seafood cold storage room;

They are mainly used for the temporary turnover and trading of fresh seafood. The general storage period is 1-2 days, and the temperature range is -5 ~ -12 ℃. If the product is not sold within a 1-2 day period, the seafood should be moved in the blast freezer room for quick freezing.

2, Frozen seafood cold storage room;

They are mainly used for long-term  preservation of frozen seafood. The general storage period is 1-180 days, and the temperature range is -20 ~ -25 ℃. Quick-frozen seafood from the blast freezer room  is transferred to this low temperature cold room.

3, Fish and seafood blast freezer cold room;

The quick freezing time is generally between 5 hours and 8 hours, and the storage temperature is between -30 ~ -35℃;

The difference between seafood cold storage room and common cold storage room is that seafood generally contains more salt, and salt has a corrosive effect on materials. If the cold storage does not do some anti-corrosion  treatment, it will rot and perforate after long-term corrosion. We advice that using stainless steel panels for building fish and seafood cold room. Evaporators use blue hydrophilic aluminum foil fins.

We offers a range of refrigeration products and services to the fish industry. Our range of cold room solutions is designed to keep your fish as close as possible to the same condition in which they were caught.

We have a choice of blast freezers and cold storage in a range of capacities suitable for storing a large variety of your products. With the short lifespan of fish once caught, it is essential for them to be quickly and permanently frozen almost from the time of being caught to the time it is purchased by the consumer.
