Stationary Air Cooled Chiller For Food Processing

Stationary Air Cooled Chiller For Food Processing

Stationary air-cooled chiller is a type of cooling device that absorbs heat from process water, and the heat is dissipated by the fans and transferred to the air around the chiller unit,it does not include a pump and water tank. The main component is a self-contained chiller that must be piped to a pump and a separate tank or pool to function.This chiller system typically has separate controls for the chiller and pump or pumps, with electrical connections for each component. Ideally, the controls should be wired together to prevent the chiller from cooling until the circulation pump is running.Stationary air-cooled  chiller is equipped with Panasonic/Danfoss scroll compressor for 1/2HP to 60HP cooling capacity , semi-hermetic hanbell /Bizter screw compressor for above 30HP cooling capacity usingR407c, R22, R134a, , and R404a are all available depending on the chiller unit working condition, application requirements, and ambient temperature. The chiller temperature control range is from -30℃ to +25℃.Stationary air cooled chiller chiller is not only used for cooling food processing , but also widely used for die casting, rubber, printing, plastic injection molding, beverage production, metal polishing, the pharmaceutical industries and other other industries.

Stationary air cooled chiller for food processing is also called food processing chiller or food processing cooling system .Because food processing requires cooling, chillers also need to play a role in the food industry. It can cool food at high speed, better meet packaging requirements, and can also control the temperature of fermented food. The special refrigeration unit for the food industry is an indispensable chiller in the food industry. It is widely used in the food processing industry to quickly cool products and keep the temperature constant.

In many food industries, after food is processed at high temperatures, in order to be packaged quickly, the temperature of the food needs to meet the packaging requirements. At this time, it is necessary to use chillers in the food industry to process processed foods quickly and efficiently. In addition, during the food fermentation process, different temperatures are needed to stabilize the fermentation needs. Therefore, in order to ensure the quality of product fermentation, we also need to use chiller units dedicated to the food industry. In addition to the above two aspects, a chiller is also needed in the process of food preservation. In short, whether it is processing, fermentation, or preservation. Chillers do play a big role in the food industry.

5.Stationary Air Cooled Chillers Vs Stationary Water Cooled Chillers

▪ Air cooled chillers require less maintenance than water-cooled units.

▪ Air cooled chillers do not require a water cooling tower or a condenser water cooling pump.

▪ Consume approximately 10% more power than a water-cooled unit due to wet surfaces transferring heat better than dry surfaces.

▪ Air-cooled chillers require less water.

Air-cooled chiller systems are widely used in places where water resources are not sufficient or water quality is not very good. The most convenient part is that air-cooled chiller systems do not require cooling towers, so they are easy to install. (If an air-cooled chiller isn’t what you need, please refer to water-cooled chiller.)

How I can Choose the Right Stationary Air Cooled Chiller?

There are FIVE important chiller specifications you need consider when you choose a chiller for your application :the cooling capacity for chiller ,the voltage required for operation, the associated pump horsepower and flow rate (contact us for custom selection), refrigerant, and the evaporator type.

7.1 Calculate Right Cooling Capacity For Chiller

One of the most frequently ask about how we can know the cooling capacity for chillers.  We use KW ,Ton, But/h,Kcal/h to choose chiller cooling capacity :1 KW=860 kcal/h ;  1 TON=3.517 KW;

1 KW=3412 Btu/h;

There is also a formula to calculate the cooling capacity for chiller:.

Cooling Capacity(kw)= Flow Rate(m3/h)*Temp Change(T1-T2)/0.86

Heat Load= C(specific heat)* M(quality output per hour )*Temp Change(T1-T2)

Oversize the chiller by 20% Ideal Size in KW = KW x 1.2

Noted : T1:Incoming Water Temperature (℃)      T2:Required Chilled Water Temperature(℃)    

For example, what size of chiller is required to cool 10m³ water from 35°c to 15 °c in 1 hour?

Temperature Differential = 35℃-15℃=20℃

Water Flow Rate = 10 m³/hour

Cooling Capacity in KW = 10 x 20 ÷ 0.86 = 232 KW

Oversize the chiller = 232 x 1.2 = 278.4KW

278.4 kw cooling capacity for chiller is required.

7.2 Power

Different countries and regions have different standards for industrial electricity, the common power supplies are 208-230V, 380-420V,440-480V,50Hz or 60Hz, 3phase.

Such in Philippines ,the power supply is 220V 60HZ 3PH , 380V 60HZ 3PH ,460V 60HZ 3PH;

in Singapore and Malaysia ,the power supply is 415V 50HZ 3PH;

in Mexico ,the power supply is 220V 60HZ 3PH;

In USA ,the power supply is 208V 60HZ 3PH;575V 60HZ 3PH;480V 60HZ 3PH and so on

7.3 Refrigerant

R22, R407C, R404A, R134A are optional choices.

R22: good cooling effect, but R22 is considered a powerful greenhouse gas, so it’s forbidden in most countries.

R407C: a good replacement for R22, good cooling effect.

R404A: suitable for application that requires low temperature(below -10°c).

R134A: a non-flammable gas used primarily as a “high-temperature” refrigerant, suitable for air-cooled chiller working at a high ambient temperature above 50℃.

7.4 Evaporator Choose

Air cooled screw chiller generally uses one evaporators: just is shell and tube heat exchanger.Shell and tube type evaporator, which requires an additional water buffer tank to connect.

7.5 Buffer Water Tank Capacity Choose

Buffer tank’s capacity can be customized according to specific needs. It can buffer a larger heat load, store more chilled water .

Shipping Way of Stationary Air Cooled Chiller

As a professional water chiller supplier &exporter,we have our own shipment forwarder to arrange the shipment .Our chiller machine is with plywood packing,which prevent damage during transportation and meet export standards.There are three ways can delivery your chiller unit :

1. Ship by Air: As the chiller is with compressor ,water pump and fans ,the compressed refrigerant and oil inside the compressor is a dangerous item with the possibility of explosion , so it needs to release the compressed refrigerant before transportation. (It means that water chiller without refrigerant when choosing this shipping way. After the machine arrives at your destination, you need to add refrigerant by local professionals. The airline company also request us to provide many documents to prove that the chiller not a dangerous product. The freight cost by air is very high may be higher than the cost of chiller , So By air for delivery is not the mode of transport recommended to our customer.

2. Ship by Sea: The transportation time is longer than by air , but the freight cost is cheap ,and there is no need to add refrigerant after the equipment arrives at the destination.This shipping way is the most suitable mode of transportation for you to delivery your local port.
