KINKAI Heat Pump Dryer Introduction
KINKAI Heat pump dryer is use of reverse Carnot principle. With free air to absorb heat and transfer it to the drying chamber, drying room temperature to achieve improved, with the appropriate humidity and dehumidification equipment to achieve dry materials. Heat pump dryer Compressor - heat exchangers - Chokes - heat sink (outside the machine) - Compressor and other devices constitute a refrigerant cycle system.
How does our dryer machine work?
1. Dryer evaporator of refrigerant absorb the air from outside
2. then compressor works that make the air temperature rise
3. heat exchanger change the hot air into drying chamber
4. final fruits will be dried by the hot air circulating in drying chamber

After installation,during the guarantee period,our company will be responsible for problems caused by quality of production or raw material except the damageable spare parts of heat pump caused by incorrect man-made operation.
Feature
High temperature heat pump drying dehumidifying drying room.
1. Drying process completely meet the requirements of food hygiene.
2. Cleaning and hygiene in the good condition, the finished colour and lustre is bright.
3. Automatic control, reduce the labor and the labor intensity.
4. During drying, there is no water/gas/solids generating, the green environmental protection; Good and comfortable working environment .
5. Long service life, low operating cost, good economy.
6. Temperature and humidity is automatic control; Small fluctuations in the temperature and humidity in drying process, the drying quality is stable and reliable.
Drying machine FAQ
1. High pressure protection
A. Hot air circulating fans does not working
a1. AC contactor use for hot air circulating fans overloading protection(please check power source whether lack phase/connecting port or voltage not stable)
a2. Part of hot air circulating fan not working(check whether the fans have many ON/OFF switch or some fans was burned)
a3. Fan was damaged (replace new fan or uninstall damaged fans)
B. Too much more products on trays or too much more trays on trolleys lead to block hot air (hot air cannot circulating in drying chamber or too slow wind speed, usually two tray's distance at 8-10cm is reasonable).
C. Electronic expansion valve throttle opening too small; or jammed.
c1. Controller adjust electronic expansion valve's opening to small automatically(temperature sensor not accurate-change installation place, exchange 1# and 2# sensor's position)
c2. Electronic expansion valve does not working(turn valve body)
D. Chamber's temperature too high(set lower temperature)
E. Refrigerant is not high temperature type, re-fill gas.
2. Low pressure protection
A. Leak gas(check leak point, repair)
B. Weather too cold(expand check time for low pressure protection, or charge low temperature gas, e.g. R22/R417A)
C. Electronic expansion valve opening too small(adjust bigger)
3. Exhaust temperature too high protection
A. Leak gas(check leak point, repair),
B. Electronic expansion valve does not working(turn valve body).
4. Temperature sensor error(replace new one)
5. Discharge moisture too slow or does not discharge moisture
A. Dehumidify fan was damaged,
B. Controller go wrong,
C. Dehumidify fan power
