The difference between a freezer room and a blast freezer room

Do you need a freezer room or a blast freezer room?

When deciding on a freezer room and blast freezer it’s important to know the options available and how they best serve your business. This can greatly impact how you store your products and whether or not they meet the regulations that apply to them.
In fact, when comparing some freezers, they may not be as similar as they first appear. So how do you know what freezer you need and why you need it? Depending on your business, you may require a freezer room, a blast freezer or both, and this is why.

The Temperature Difference Between a freezer Room and a blast Freezer room

Freezer Room
A freezer room is designed to store a range of products and materials at subzero degrees which will prolong the lifespan of food. However, unlike a blast freezer, a freezer room cannot freeze products at a rapid rate.
The freezer room temperature ranges is from -25C° to -18C°.
We can store frozen meat, frozen seafood, frozen chicken and frozen beef etc inside the freezer room.

Blast Freezer room

A blast freezer room cools its contents quickly, rapidly dropping the temperature. Flash freezing in a blast freezer is one of the safest and most effective ways of preventing bacterial growth.

Blast freezer room hold temperatures between minus 28 degree down to a chilly minus 40 degree. As a result, the ice crystals that form in the process are small, causing less damage to the products. This captures the products freshness and nutritional value.

Blast freezer rooms are sometimes referred to as shock freezers. The idea of this type of freezer room is to very rapidly bring down the temperature of (usually) foodstuffs or fresh produce, freezing them very quickly.

The Application Difference Between a freezer Room and a blast Freezer room

Most food service businesses have both a freezer and cold room. It all depends on what food you want to store and for how long.
However, foods and other perishables that you will keep for a short period and have ready for immediate use can be stored inside a cold room. The longer the required storage time and the lower the temperature range.
freezer rooms are the space where you will keep meats and other products that you require to keep on hand for a long time period.

What is blast freezer used for?

A blast freezer, also known as a shock freezer, is a type of freezer which is designed to very rapidly bring down the temperature of the contents being stored. They are widely used in commercial kitchens and in the frozen food industry for fresh produce, ice cream, pre-prepared meals and vegetables or fish.

Blast freezing vegetables, Blast freezing fruits, Blast freezing meat, Blast freezing chicken, Blast freezing fish, Blast freezing foods, Blast freezing ice cream and Blast freezing bakery.

How to do cold room operation and maintenance?

For any cold room to function efficiently, it is important that the refrigerated cold room is maintained properly. The efficiency of the room can be made possible if the room is maintained properly.

1, The refrigeration system and the cold room:

For the room to be efficient it is important that the refrigeration system is efficient. The refrigeration system needs to be perfect to make sure that the inner temperature can be maintained.

The maintenance of the refrigerated room should also include the maintenance of compressor. The compressor is important part of the cooling system of the room. The compressor needs to be cleaned repeatedly to make sure that the refrigeration of the room is able to maintain the desired temperature.

The coils of the fan, condenser and the evaporators also need to be cleaned repeatedly so that the refrigeration system can function properly. These parts of the cold rooms should be done on daily, monthly, quarterly and annual maintenance checks.

2, The daily maintenance checks:

The daily maintenance checks of the cold rooms include the following practices:

  • Spillages should be cleaned up IMMEDIATELY
  • Check the cold room temperature is correct for your products
  • Inspect the evaporator for a build-up of ice
  • Check the compressors in the walk-in cold room for oil leakage
  • Check the Freon levels in the cold storage room

3, The monthly checks:

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.

Quarterly maintenance practices:

Perform all the monthly maintenance practices. They should not be ignored. If ignored they can lead to increase in the energy consumption and inefficient cooling.

The overall functionality of the cold room should be tested to make sure there are no leakages or damage to the cold room.

Annual maintenance practices:

The daily, monthly and the quarterly maintenance checks should be carried out without any exception.

By carrying out all the maintenance steps mentioned above, the efficient functionality of the room can be ensured.

The heat exchanger should be washed chemically. This will help in removing any impurities which may become a hindrance in the efficient functionality of the room.

Cold Room Storage Temperature and Time of Fruits and Vegetables

The cold room storage temprature and time of fruits and vegetables is different according to different varieties of fruits and vegetables. It is related to many reasons such as: pre-cooling, quality of fruits and vegetables, varieties of fruits and vegetables, Packaging methods of fruits and vegetables, etc.

Without cold room, most fruits and vegetables will not stay fresh for more than a few days. As soon as fresh produce is harvested, it begins to deteriorate and dangerous bacteria will start to develop.

Proper storage conditions – temperature and humidity – are required to maximize storage life and maintain quality of harvested fruits and vegetables.

Fresh fruit need low temperature and high relative humidity to reduce the respiration and slow down the metabolic processes. The table below indicates optimal temperatures and moisture conditions for some common fruits and vegetables.

Storage temperature for various fruits and vegetables

1 Around 0°C: Most of the roots and leafy vegetables are cool fruits and vegetables (originally produced in temperate and frigid zones), and their suitable storage temperature is 0-2°C, not lower than 0°C. Cabbage, spinach, cauliflower, celery, carrots, peaches, grapes and apples are just picked, don’t put them in the cold storage immediately, because low temperature will inhibit the enzyme activity of them. Therefore, it is best to store these fruits and vegetables at room temperature for one day before putting them in the cold room.

2, 10°C: Like tomatoes, cucumbers, bell peppers, lychees, bitter gourds, cowpeas, pumpkins and other vegetables are suitable stored in temperature about 10°C;

3, Above 10°C: Tropical fruits are best stored in a dark and cool place. If it must be placed in a cold storage, it should be placed in a higher temperature cold room, and the storage time should not exceed two days. The suitable storage temperature for bananas, lemons, pumpkins is 13-15°C.

Guide to fish and seafood cold storage room

Seafood cold room is applied to store fish and seafood etc. The low temperature or ultra low temperature greatly decrease the activity of all kinds of  bacteria and micro organism and limit their growing and keep the freshness of fish and seafood.

Our comprehensive guide will help you to store fish correctly, so you can make the most of your produce.

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.

How to properly store fish?

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℃;

There is also -60~–45℃ freezer room for storing tuna etc..

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.

The best way to store fresh fish

As fresh fish has an incredibly short shelf life, normally around 1-4 days, proper storage is vital to retain quality and taste. Legally, fresh fish containing no frozen water must be stored at or close to 0°C. Anything above 4°C will result in rapid deterioration, causing fish to quickly become unfit for consumption.

Using a temperature controlled refrigeration unit will help to successfully chill and maintain your fish at the required level. Once in storage, this temperature should be regularly checked and any produce above 4°C should be thrown away. Any fish taken out of a controlled temperature unit should be used immediately and on no account should warm fish be returned to cold storage.

Cold stores regulate temperature by releasing a continuous flow of cold air around the unit and if this flow is obstructed, the temperature will suffer. Therefore, to get the most out of your refrigerated cold stores and the most out of your fish, avoid packing above capacity. Much like packing and storing frozen fish, you should never pack fresh fish together too tightly, as this will affect the temperature and ultimately the quality of your produce.

To ensure fish stays as fresh as possible, it’s always recommended to keep it in a professional cold store unit. Regular domestic fridges simply cannot offer the same level of temperature control and can leave you with unsafe fish and heavy wastage.

Potato cold storage room-how to store potatoes long term?

Potatoes are important vegetable crops in our life. The harvested fresh potatoes can also be kept fresh in the cold storage room, it can be stored as long as 8 months in the cold room.

Potato cold storage preservation technology mainly includes three points: potato harvesting, cold storage room period and delivery management.

I  Potato harvesting

1,The potato harvest time is selected on a sunny day. Watering should be stopped 7-10 days before harvest, which can promote the aging of potato skins and reduce the moisture content in the tubers.

At this time, the land is dry, and the potato pieces that are excavated are less muddy, and part of the water is distributed, making the skins dry and conducive to storage.

2, After the potatoes are harvested, the next step is to grade the potatoes to eliminate the potatoes with diseases and insect pests.

We will choose good quality potatoes that are moderate in size (usually medium), harmless, and disease-free for storage.

II Potatoes pre-cooling

After the potatoes are graded, they are pre-cooled. There are three pre-cooling methods: natural pre-cooling, cold storage pre-cooling, vacuum pre-cooling.

The pre-cooling time of the cold storage room is not more than 48 hours, and the pre-cooling is stopped when the temperature reaches five degrees higher than the storage room temperature. The pre-cooling time is scheduled within 12 hours after harvest.

III  Potato cold storage room

Temperature cooling down in advance is to help the potatoes better adapt to the low temperature environment of the cold storage. Generally, they are turned on and cooled 3 to 5 days before the potatos put in, and the temperature is controlled at about 1 to 4°C.

(1) Cold storage room temperature

AC potato cold storage room temperature is 3℃~5℃.

The room temperature is required to reach the specified storage temperature within 48 hours. The storage room temperature is required to be stable during the entire storage period, and the fluctuation does not exceed ±1℃.

(2) Relative humidity

The relative humidity of the potato cold storage room is kept at 80%~90%.

If the humidity is higher than this, the potatos are easy to rot and germinate early; if the degree is too low, the potatoss are easy to lose water, lose weight, become soft and shrink, and lose their edible and seed value.

(3) Gas management of potato controlled atmosphere storage room

It is recommended to be controlled as: oxygen concentration 3%~5%, carbon dioxide concentration 2%~3%.

The respiration of potatoes is still going on after harvesting. Potatoes with too low oxygen content will be hypoxic. In some cases, they will lose their germination ability, and in severe cases, they will cause suffocating rot.

The appropriate concentration of carbon dioxide concentration can also slow down the respiration of fresh potatoes, and can effectively delay the initiation of the respiratory jump.

But the carbon dioxide concentration can not be too high, too high carbon dioxide will cause potatoes to be forced to undergo “anaerobic respiration”.

refers to the process in which the respiratory substrate of potatoes cannot be completely oxidized under hypoxic conditions to produce alcohol, aldehyde, lactic acid and other products, and at the same time release a small amount of energy. The reaction equation is as follows:

Anaerobic respiration is not good for potato storage, it will consume more nutrients stored in potatoes and accelerate the aging of fruits and vegetables.

In addition to controlling the carbon dioxide and oxygen components, the cold room also controls the concentration of ethylene. Ethylene can quickly increase the respiratory intensity of potatoes and accelerate the ripening of potatoes. The ethylene removal machine of the air conditioning warehouse can control and reduce the concentration of ethylene.

IV Potatos taken out from cold storage room

1, The taken out potatoes should be warmed up slowly to prevent the dew and deterioration of the potatoes caused by the excessive temperature difference;

2, Pay attention to the handling process: handle, put, and move gently to avoid mechanical damage;

3,Cold chain transportation should be implemented for medium and long-distance transportation, and room temperature transportation can be selected for medium- and short-distance transportation.
