Functions of Cold Room for Sale

The controlled temperature in the beer production process is very important. Depending on the type of beer you brew and how you serve it, you may want to control temperatures in the 0℃ range (for storage) or you may need something closer to 10℃ (for fermentation). For storing kegs or running tap lines to your tasting room, you probably want to maintain temperatures between about 0℃ and 5℃. If you are doing all of these things, you may even need to switch between higher and lower temperatures at different stages of the process.

The trick is that you need to be able to control the temperature precisely so that you can ensure that every batch you bottle and pint you pull will be perfect. Reliable controlled cold room is important.

Potato Chiller Room in Pakistan

Potato Chiller Room in Pakistan


Potato chiller room is the storage facility for potato or other vegetables that uses cooling facilities to create suitable humidity and low temperature conditions. Also known as the cold room. The potato chiller room is the place to process and store products in controlled condition. The chiller room for potato can get rid of the impact of the climate, then extend the shelf life of various products to regulate the market supply.


Potato Chiller Room
The Chiller room is mainly used for constant temperature storage of food, dairy products, aquatic products, fruits and vegetables, cold drinks, flowers, green plants, tea, medicines, chemical raw materials, electronic instruments and the like.
Chiller room is actually a kind of cold air equipment combined with low temperature. The chiller room (refrigerator) is also a kind of refrigeration equipment. Compared with the refrigerator, the cooling area is much larger, but they have the same cooling principle.

1.Characteristics of Potato Chiller Room
The main storage temperature of potatoes in chiller room is 3-10℃, and the activity of amylase in potatoes increases at 0℃, which accelerates the hydrolysis of starch into sugar and enhances the respiration of potatoes.
Relative humidity of storage environment also has a great impact on potato storage. When the air is dry, water evaporates quickly, potato skin shrinks, and the air is wet and easy to dry, which will affect the quality of potatoes.
Potato chiller room temperature characteristics: fresh potatoes on the market storage temperature 4-7℃, relative humidity 95-98%, used for processing potatoes, temperature 8-10℃, relative humidity 95-98%, seed potatoes storage temperature 0-3℃, relative humidity 95-98%.



2.Storage Methods and Management
The dormancy period of potatoes is usually 2 to 4 months after harvest and length of dormancy period varies with varieties. The dormancy period of late-maturing varieties was short and that of early-maturing varieties was long. Different maturity also affected the length of dormancy period. The dormancy period of immature potato tubers was longer than that of mature potato tubers. Storage temperature also affects the length of dormancy period. The dormancy period of potato blocks stored at a suitable low temperature is long, especially at the early stage of storage, the low temperature is very beneficial to prolong the dormancy period.
Potatoes are rich in starch and sugar, which can be converted into each other during storage. When the temperature drops to 0℃, the activity of starch hydrolase increases, monosaccharide accumulates in potato tubers, sweet potato tubers, poor edible quality and browning of processed products. If the storage temperature rises, the monosaccharide will synthesize starch. When the temperature is higher than 30 and lower than 0℃, the sweet potato core is easy to blacken.

The suitable storage temperature of potatoes is 3 ~ 5℃, but potatoes used as fried potato chips or fried potato chips should be stored at 10 ~ 13℃. The suitable relative humidity for storage is 85% to 90%. Excessive humidity tends to increase rot, humidity is too low, water loss increases, and potato tubers shrink.



3.Running under Fixed Conditions
Storage methods and management of harvested potato chips can be stacked in a cool and ventilated room, cellar or shade. Let potato chips heat and evaporate excessive moisture. Promote wound healing. Potato piles are generally no more than 0.5. The width is not more than 2 m. Ventilation pipes should be set up in proper amount in the reactor. In order to ventilate and cool down. Shade with a straw curtain. During the pre-storage period, the rotten potatoes should be checked and removed frequently, and the rotten potatoes should be handled lightly to avoid mechanical damage.
After 2-3 weeks, the skin of potatoes became aged and dry, the epidermis cells were corked, callus was formed, and the rotten potato pieces were basically selected and stored formally.
Potatoes were preserved with fruit and vegetable smoking agent after they entered the chiller room 5 g per cubic meter. It can be stored in cold storage. It can also be packed and stacked. The relative humidity is 85-90%.


Chiller Room Security Requirements
Transportation vehicles for chiller room should meet the requirements of relevant standards.
The chiller room should be reasonably partitioned and set with relevant signs to facilitate the storage, transportation and management of goods in the warehouse.
Emergency lighting, door lock and alarm device should be set up in the chiller room, which can be rescued or alarmed for help.
The shelves in the chiller room should have sufficient strength and rigidity.
There should be anti-smashing guardrails around the chiller room door, and there are eye-catching signs.
The assembled chiller room should be provided with a balance window.

Walk in Cooler Refrigeration Unit

Walk in Cooler Refrigeration Unit


Walk in cooler refrigeration unit is an essential component for cold room. The walk in cooler refrigeration unit can keep the cold room temperature between -15 degree to 10 degree. Cold room is the basic facility of restaurants, hotels, supermarkets, and any other place that needs to store fresh, frozen, or pre-cooled food products. These walk-in cold room has enclosed, refrigerated storage spaces generally smaller than 3000 square feet and can be used for things such as storing perishable food items or packaging food.









Walk-in coolers are often used as medium-term cold storage facility which are equipped with standard walk in cooler refrigeration units acting as short-term storage and refrigerated warehouses acting as long-term storage. Just like any refrigeration system, walk-in coolers use an evaporator inside the unit and a condenser outside the unit to move heat outside, thus cooling the inside.

Refrigeration is important for maintaining a proper, unbroken cold chain. Using dairy as an example, after the cows are milked, their milk is pasteurized and rapidly chilled. Once the milk has been chilled, it must be maintained at that low temperature from the farm to the grocery store, including during bottling and shipping. If the cold chain is broken, bacteria or fungus can grow, making the food unsafe for human consumption. The United States Department of Agriculture requires that business-owned refrigeration systems have an internal temperature of 40°F or below for refrigerated food and 0°F for frozen food. Businesses operating refrigerators or freezers above these temperatures face fines and other penalties, so maintaining a reliable temperature is imperative. One of the most popular types of business-owned refrigeration systems is the walk in cooler.


Indoor and Outdoor Walk in Cooler Refrigeration Unit

When it comes to walk in coolers, it’s very important to choose a refrigeration system that works best for your cold room. Since we offer models with different BTUs and KMs, as well as units designed for indoor or outdoor use, you’ll be sure to find the unit you need for the size and location of your walk in cooler.

Walk in cooler refrigeration unit have two main parts, indoor unit and out door unit. Indoor unit also called air cooler or evaporator, out door unit also called condensing unit.

When it comes to walk in cooler refrigeration unit , which part is be most concern? Compressor, yes. Our company mainly us Germany Bitzer compressor and American Copeland compressor. Different compressor have its own advantage. Except compressor, which part also very important? Yes, the coil of indoor unit and outdoor unit. Coil, also called evaporator, it was composed by copper pipe and aluminum fin.


Refrigeration Cycle System

The refrigeration cycle for walk in cooler refrigeration unit is exactly the same as residential air conditioning system. However, the operation of the physical component is slightly different. Walk in cooler refrigeration unit system is controlled by a close on rise in temperature thermostat. You will find either a mechanical type with a sensing bulb or a digital thermostat with a thermistor. Most of the walk in coolers that require repair will be older and may have been retrofitted with a digital thermostat. The thermostat of the walk-in cooler determines the air temperature within it. When the temperature rises above the level of the thermostat, the condenser unit turns on to start a new cooling cycle. The unit’s fans pull air into the unit and then over the condenser’s coils.



The coolant within the coils pulls the heat from the air as it passes over. The cooled air then continues to move out the back of the unit, cooler than it was when it first entered. As the fans continue to blow air over the condenser, the air temperature within the walk in cooler will lower until it is once again below the level set by the thermostat. The coolant within the condenser coils will be continually pumped during the cooling cycle. This ensures that the coolant does not heat up too much before being given a chance to cool down again.



Why choose us?

OnlyKem can supply the whole set of walk in cooler refrigeration unit, include indoor unit, outdoor unit and control panel etc. Our refrigeration unit have following feature:
Temperature allow customized.
Defrosting system allow customized.
Brand accessories and long time service.

Chiller Room for Sale

Chiller Room for Sale

Chiller Room for Sale is widely used to store all kinds of fruits. Deterioration of fruits during storage depends largely on chiller room temperature. One way to slow down this change and so increase the length of time fruits can be stored, is by lowering the temperature to an appropriate level. It must be remembered that if the temperature is too low the produce will be damaged and also that as soon as the produce leaves the cold store, deterioration starts again and often at a faster rate.



It is essential that fruits are not damaged during harvest and that they are kept clean. Damaged and bruised produce have much shorter storage lives and very poor appearance after storage. Dirty produce can introduce pests and mold into the chiller room for sale.

The produce should be harvested carefully using a sharp stainless-steel knife. The fruits should not be placed on the ground where they could pick up dirt. Either a clean harvesting basket or clean mats should be used.

It is essential that the fruits are harvested at the correct harvesting time.



If the produce is dirty it should be cleaned before fruit chiller room. The water used has to be kept clean or fungus spores will be spread throughout the produce.

Some fruit need their outer leaves removed before storage. However, usually it is better to leave the leaves on during storage to reduce moisture loss, and then remove them before sale.

Dipping the produce in cool water to remove field heat can reduce the energy requirements of the store. However, this can spread fungus spores throughout the produce. A suitable alternative is to pick the produce either early in the morning when it is cool or late in the evening and leave it overnight to cool down.
Temperature

All fruits have a “critical temperature” below which undesirable and irreversible reactions or “chill damage” takes place. The fruit chiller room temperature always has to be above this critical temperature. One has to be careful that even though the thermostat is set at a temperature above the critical temperature, the thermostatic oscillation in temperature does not result in storage temperature falling below the critical temperature. Even 0.5°C below the critical temperature can result in chill damage.


Storage conditions

There are basically three groups of fruit: those stored at 0 – 4°C; those stored at 4 – 8°C; and those that require a storage temperature above 8°C. It is often more convenient to concentrate on one of these groups.

Relative humidity
For most produce, a high but not saturated, relative humidity is required, for example, 85 – 95%. There is always some moisture loss during cold storage but excessive moisture loss is a problem. It is essential that the relative humidity is kept above 85%. This can be done by:
• Allowing the produce to reach storage temperature and then covering in plastic.
• Sprinkling the produce with water, this should be done before storage since if the vegetables are sprinkled during storage condensation occurs at the refrigeration unit.
Packing system

A packing system is required so that the produce can be loaded and unloaded easily and safely. This can be a system using crates that can be stacked or a more complicated system using racks and trays. It is important that the crates are small enough to be moved easily when full of vegetables, easily and safely stacked, strong enough to hold the weight of the other crates. It is essential that the airflow is not restricted, therefore a two foot gap should be left between the walls and the crates and three foot gap left between the crates, the ceiling and refrigeration units.


Fruit Chiller Room for Sale

There are PUF panel, refrigeration unit, unit cooler and other components for fruit chiller room.

OnlyKem’s chiller room panels not only prolong the life of your products, but will also save you money, as they’ll reduce your energy usage. It can be expensive to retain temperatures for fruit chiller room. OnlyKem PUF panels provide R-values of up to 50, enabling you to retain the temperature you need to cool your fruit without requiring your chilling equipment to perform as hard or as long. You’ll see this difference reflected in your energy bills throughout the year.

We will choose Copeland or Bitzer compressor for your condensing unit of fruit chiller room for sale. The function of the compressor in the fruit chiller room is to suck in the vaporized refrigerant from the evaporator by the movement of the piston, pressurize the sucked gas into a high pressure body and enter the air cooled condenser, and suck heat with cold water or wind, so that the high pressure gas condenses into a liquid and enters the air reservoir. The suction and extrusion of the compressor are performed simultaneously. Between the compressor and the expansion valve is a high pressure part, and only the high pressure can maintain the refrigerant in a liquid state.

Berry Cooler Room for Sale in USA

Berry Cooler Room for Sale in USA

Why does Berries need cooler room to keep?


Berries are fruits with high moisture content and pulpy pulp such as grapes, red cherries, strawberries, gooseberries, blueberries, they start to deteriorate as soon as they are harvested because they are cut off from their source of water and nutrition. They lose weight, texture, flavor, nutritional value and appeal. Cooling significantly slows down the rate of deterioration, thereby increasing the storage life of the produce.


Therefore, we need to choose cooler room to store them, in order to reduce the spoilage and deterioration of berries,

Turn Key Cold room specifications in Myanmar

Cold room usage: For frozen spinach storage

Cold room external dimension: 37200mm*23460mm*6450mm

Cold room layout: total six cold rooms and one corridor

Cold room insulation panels: 150mm thickness PU sandwich panels with good insulation effect, there is no cold losing, it will save power for customer.

Floor of cold room: XPS panel + cement. Customer need to drive forklift into cold room for loading and unloading goods, so we designed this floor system, it is strong enough to bear it.

Cold room temperature: -25 degrees celsius, keep spinach be frozen.

Ambient temperature in Myanmar: +45 degrees celsius.

Our solution as follows:
1.Condensation method: Evaporating cooled condenser.



Ambient temperature in Myanmar is very high in summer, it can reach 45 degrees celsius even more higher temperature, air cooled condenser is not workable, because air cooled condenser uses hot air as medium for the heat exchange, it is not efficient with so high temperature.

Finally our engineer chose evaporating cooled condenser, in this solution, it uses water and air as cooling medium exchanges the heat with high-heat gaseous refrigerant medium and hence the refrigerant medium becomes liquid. Inside, there is water distribution system, heat exchange coil, Outside, there is water circulating pump, electronic water curing device and propeller fans on the top of heat exchange coil. Evaporating cooled condenser will be more and more popular in the tropical area.

Advantages of evaporating condenser:

Excellent heat exchange performance with water

Convenient and realizable on-line maintenance

Small floor space and low investment

Convenient transportation and installation

Low operating cost and energy saving

Low fault rate

Slope collecting basin with convenient clean out

2. Compressor unit type: Origianl new German Bitzer brand, screw compressor, parallel system.



Electricity is very expensive in Myanmar, so customer wants the energy saving solution; Besides, sometimes they don’t put full frozen spinach in the Turn Key cold room, so all compressors don’t need to work all the times. Considering these points, our engineer suggested that parallel system for customers.

Advantages of parallel system:
Integrated PLC control system.
Automatic control system: it can adjust the number of working compressors automatically according to the cooling capacity required in cold room. It means that not all compressors keep working always, so it is energy saving than the single unit.
Remote monitoring system: we can help customers debug machine in China, so it can realize online-service in the future, it is very convenient and in-time after – sales service.
Backup function: If one compressor has problems, other compressors can replace it for working. It can keep cold room temperature continuously. Spinach won’t be affected because of the sudden problems.
Long lifespan: Because it can adjust the compressor working time automatically according to the cooling capacity required, so the compressors have time of rest, their lifespan is about 30% longer than the single unit.
OnlyKem installation team for Myanmar Turn Key cold room project!

Our experienced refrigeration engineers worked for designing and installation guiding for customer. There ware three stages for the whole installation.
Firstly our engineer inspected customer’s site, in order to check if it is suitable or advantageous for good running and installing of machines, our engineers gave some useful suggestions in this stage, such as we suggested customer utilizing high quality water, because evaporating cooled condenser need water as heat exchange medium, low quality water will have water rust or impurity, after long time, it will reduce heat exchange rate.
Secondly, our engineer designed professional drawing according to actual site, it is helpful for the fast installation. With the drawings, installation team understood some details very easily and clearly.
Thirdly, our engineer helped debugging machine until they worked well!
