Speed and efficiency are two characteristics of vacuum cooling that cannot be surpassed in any other way, especially when cooling packaged, boxed or palletized products.
Vacuum pre cooling system
1. Gas: R404a, R134a, R22, or other
2. Compressor: Germany Bitzer screw type/ Taiwan Hanbell screw type;
3. Vacuum pump: Germany BUSCH / Germany Leybold
Vacuum cooling is a fast type of pre-cooling that also helps preserve vegetables by placing them almost in full vacuum. Field heat and heat from the biological processes of vegetables are used when water is converted into steam
Fast Cooling Vacuum Cooler for Vegetable
4 PALLET CAPACITY
Design Basis
1. Cooling capacity for four (4) standard 40” (1.0M) X 48” (1.2M) produce pallets.
2. One (1) row placed with the 48" side in line with chamber length.
3. Alternate loading of owner specified bins, 5 sets stacked 3 high, each bin 70 cm high X 110 cm
X 110 cm, total of 15 bins.
4. Ammonia refrigerant.
5. Electric powered; 415 volts, 3 phase, 50 cycles.
6. Constructed in one part; skid base, piped wired, tested and finish painted; complete ready to operate requiring on site electric power and water supply hook-up.
Detailed Product Description
1. Keeping better Fresh quality
2. Help you deliver your food for more distant markets
3.Having nice price with good quality
Our vacuum pre-cooling system can benefit you on fast cooling with full automatization,equalized cooling process,clean refrigerating without contamination,long term storage,and long distance transport without spoilage.
Product competitive advantage:
Fruits,vegetables and flowers through vacuum precooling process possess the competitive advantages as bellow, comparing to the ones without vacuum precooling.
(1)Keep fruits,vegetables food and flowers fresh and good taste,so that they can be sold in good price for benefit of selling.
(2)High cooling rate,in general it just needs 20~30 minutes to cool down the goods,and it is nothing to do with the harvest time.But it will cost 10~12 hours if you use cold-storage,and it can only process the fruits and vegetables harvested in morning.
(3)Cooling fruits and vegetables equally,rapidly,neatly.
(4)Only 2~3% of the moisture in weight is got rip off,so that the total weight will not decrease,and lead the part of it to dried up,transformed.
(5)If the fruits and vegetables are harvested in rain,moisture can be removed from surface in vacuum condition,vegetables washed like carrot can eliminate surface moisture in the same way,and will not cause damage during transporing process.
(6)Comparing with fruits and vegetables which are not frigerated,thanks to the long keeping fresh ime,our products are applicable to long-term storage and long-distance transport,and possess expansive business prospects.
Electrical
1. Electric power panel designed for 415 volt 3 phase 50 cycles.
2. Main circuit breaker for owner supplied incoming power connection.
3. Door interlocked with main circuit breaker.
4. Short circuit protection for branch circuits and electric powered devices.
5. Thermal overload protection for all 3 phase motors.
6. 115vac control transformer.
7. Industrial control power conditioner to protect control devices.
8. 24VDC regulated switching power supply for electronics devices.
9. Surge Protector on incoming power lines.
10. Powerline safety device the monitors over-voltage, undervoltage, phase loss and phase reversal.
Controls
The entire vacuum cooling system is controlled by microprocessor based industrial machine controller. Complete electronic instrumentation is provided (no mechanical pressure switches) for the automatic operation of the system and to provide for the safety of the equipment.
The controller has replaceable plug-in input and output modules with indicator LED lamps for each digital input/output circuit. Wire connections to controller shall be plug-in type terminals. This will allow for accurate and fast parts replacement, minimizing down time.
Automatic cooling cycle termination is controlled by a precision vacuum sensor accurate to 0.05 Torr (mmHg absolute) in the range of 10-0 Torr. Set points are easily adjustable by the operator before and during the cooling cycle.
The control system includes a color touch screen operator interface that will provide the means to run the system, make adjustments, and display variables and diagnostics. When provided with a list of items to be cooled, the touch screen can be programmed with individual presets of each item allowing for operation by product selection. The touch screen has a built-in data acquisition system that stores data on a removable SD card. (Flash memory commonly used in digital cameras.) The touch screen also has a dedicated Ethernet port for remote monitoring of the system on a local network or the internet. (See more information at agrefrigeration.com, Control Systems page.)

Vacuum cooling removes heat from vegetables by boiling the water contained in the vegetables. The produce is packed in a closed room and the air is withdrawn. This reduces the pressure from normal air (about 100 kPa) to a virtual vacuum (less than 1 kPa)
