Kitchen Sludge Dryer Machine high degree of automation High
After three years of hard work, Youjia Xinneng and the University
of South Korea jointly developed the world's top new air energy
sludge drying line, which will soon be successfully rolled off,
making a great contribution to the reform of coal.
Youjia Xinneng Air Energy Sludge Drying Line is a new type of
high-efficiency energy-saving and environmentally-friendly drying
equipment. Its working principle is based on the reverse Carnot
cycle principle, using a small amount of electric energy, using a
compressor to pass the working medium through the expansion valve.
The evaporator evaporates into a gaseous state, and absorbs a large
amount of heat energy in the air. The gaseous working medium is
compressed by the compressor into a high-temperature, high-pressure
gas, and then enters the condenser to release heat, and the drying
medium is heated, so that the circulation heating can be dried. The
medium is heated to 40 ° C ~ 85 ° C. Compared to the electric
dryer, two-thirds of the electricity is saved.
Youjia Xinneng Air Energy Sludge Drying Line is powerful and can be
dried, dehumidified, dehumidified and dried. The operation is
simple, intelligent and automatic operation, and no manual guarding
during the drying process, the processing volume is large, and the
occupied place is small. The unit uses a clean energy source. The
drying operation costs only 40% of the fuel dryer, 60% of the
coal-fired dryer and 30% of the electric heating equipment, which
is more than 60% more energy efficient than ordinary drying
equipment. Investment costs are recovered quickly. The automatic
PLC programmable controller is adopted to adjust the drying
process, and the drying process is adjustable to meet the
requirements of sludge drying.
Working principle of air energy sludge drying line:

poisoning and short circuit which may exist in the traditional
dryer (fuel, gas or electric heating). It is an absolutely safe and
reliable fully enclosed drying system.
5. Long service life and low maintenance cost: It is developed on the basis of traditional air-conditioning
technology. It has mature technology, stable and reliable
performance, long service life, safe and reliable operation,
automatic manual operation and intelligent control.
6, comfortable and convenient, high degree of automation, intelligent: automatic control thermostat, 24 hours continuous drying
7. Wide application range, not affected by climate: It can be widely used in heating and drying operations in food,
chemical, pharmaceutical, paper, leather, wood, agricultural and
sideline products processing industries.
Air energy sludge drying line technology advantages:
1. The air energy heat pump line sludge dryer is used. Only the PCL
control panel can adjust the time, and the whole drying process can
be completed automatically. There is no need for personnel to
guard, which greatly improves the drying efficiency.
2. Adopt intelligent electronic expansion valve control instead of
thermal expansion valve technology. At the same time, innovative
subcooling control electronic expansion valve opening degree,
innovative fuzzy-PID compliance control algorithm, realize
intelligent control of electronic expansion valve opening degree,
realize refrigerant flow control, Thereby, the intelligent control
of the drying room temperature is realized, and the intelligent
control of the defrosting is realized.
3. Using the secondary compression technology of jet boosting, the
enthalpy difference of the main circulation road is increased, the
air supply passage is increased, and the exhaust temperature is
lowered, thereby improving the heat generation of the heat pump
unit, increasing the COP value, and satisfying the low temperature
environment. Heating requirements, efficient and energy efficient.
4. Innovate the design of the horizontal circulation air path of
fresh air, return air and hot air to realize the automatic control
of wind direction, air volume and wind speed, so as to realize the
heat exchange between the return air and the fresh air in the best
state; at the same time, the innovative drying room air Strong
convection and forced hot air 360 cycle technology to avoid any hot
air dead angle, improve the temperature and drying rate of the
What are the advantages of the air energy sludge drying line:

harmful substances attached, and Youjia Xinneng Air Energy Sludge
Drying Line can effectively ensure nutrients, health and
2. The temperature distribution in the drying process is uniform,
the humidity can be automatically controlled, and the finished
product is good in color.
3. The drying process is safe and reliable, and there is no danger
of harm to people during the drying process.
4, low energy consumption in the drying process is 30% to 50% of
the cost of ordinary gas, does not require a lot of manual
monitoring, effectively reducing operating costs.
5. It has strong versatility, which reduces the investment cost and
improves the utilization rate and effective utilization rate of the
Advantages of air energy sludge drying line:
Low energy consumption: Due to indirect heating, there is no large amount of air to carry
away heat, and the outer wall of the dryer is provided with an
Low cost of use: With a large hot surface in the effective volume of the unit, the
processing time is shortened, the size of the equipment is reduced,
and the building area and building space are greatly reduced.

materials can be operated continuously or intermittently. Can be
applied in many fields.
No environmental pollution: the use of small air volume to take away the moisture in the
material, the dust material is very small, the evaporation of the
material solvent is small, easy to handle. Closed loops can be used
for contaminated materials or for conditions requiring recovery of

Air energy sludge drying line for a range of applications:
Suitable for pharmaceutical sludge, electroplating sludge, kitchen
sludge, domestic sludge, municipal sludge, river sludge, municipal
sludge, industrial sludge, paper sludge, printing and dyeing
sludge, tannery sludge, biological Fermentation bacteria residue
and various kinds of dregs and other materials are dried.
Why should the sludge be dried?
Before the sludge is dried, the water content is very high, and the
excess sludge moisture content is 99.2%-99.5%. After the
concentration tank, the sludge water content is 95%-97%, and the
water content after pressure filtration is about 80%. The reason is
to reduce the water content and sludge drying. First, the sewage
plant sludge production is relatively large, the sludge volume must
be reduced, so that the subsequent transportation and treatment are
convenient. Second, the domestic sludge treatment is mostly done by
landfill. Transported to landfills, reducing the volume can also
save space for the landfill plant. Third, after some treatment, the
sludge can be used as fertilizer and building materials. The air
energy heat pump line sludge dryer introduced by Youjia Xinneng is
a new energy-saving and environmentally friendly product, which can
effectively and effectively dry the sludge with different
