High Capacity Food Processing Centrifuge For Kitchen Food Waste
Our company specialize in the design of petroleum, chemical
engineering, coal chemical industry, steel, food, resin,
fermentation, medicine, excess sludge of water supply and drainage,
etc., completing the R&D, manufacturing and sales of dozens of
products and auxiliary equipment including the solid-liquid
two-phase, liquid-liquid-solid, solid-liquid-solid three-phase with
different parameters explosion-proof centrifuge with flammable and
explosive liquids as medium and the online real-time centrifuge
with adjustable liquid layer.
We have various unique techniques such as high-efficiency sewage
concentration, dehydration treatment, three-phase separation of
crude oil, kitchen waste, sludge and medical extract,
wear-resistant energy-saving, explosion-proof sealing and interlock
control. Our centrifuge has distinctive advantages including small
covering area, simple process pipeline; high degree of automation;
high safety protection measures; good on-site operating
environment; strong material adaptability; and stable and reliable
★ High performance stainless steel
After the high temperature hydrolysis of the kitchen waste slurry,
due to finer solid particles and 0.1-0.08 g/cm3 liquid density difference (compared with oil and water), the
centrifuge needs a separation factor of more than 3000G to achieve
the best separation effect. Model SAF2205 with high strength and
corrosion resistance is adopted to ensure the stability and service
life of the centrifuge.
★ High-dryness screw conveyor and drum structure
The dehydration of solid particles relies mainly on strong
centrifugal force, high-torque screw extrusion force (pushing
torque), and ultra-long solid particle dehydration length. The [ZK
Separation] centrifuge can generate centrifugal force exceeding
3000G, 30 ~ 50% higher than the screw pushing torque of common
centrifuges. The screw pusher torque, and the drum dehydration
length is 10 ~ 20% longer than that of common centrifuges.
★ High torque involute planetary gear differential
The ultra-high-precision torque box is based on the high-torque
involute planetary gear differential. The differentials equipped
for the [ZK Separation] centrifuge have high torque, high speed,
low heat generation and excellent heat loss. To ensure long-term,
stable operation of the centrifuge.
★ CIP washing system
The fully automatic control system is equipped with a CIP washing
system, which can effectively solve the problem that it is not
completely cleaned during the shutdown process and effectively
avoid the equipment troubles caused by artificial factors.
The main part receives design optimization in exclusiveness and
adjustability, fully considering all special requirements of
centrifuge for material and process. The most applicable model can
be provided for customers according to their materials.
High automation level
Procedures of the centrifuge such as material feeding, separation
and material unloading are all automatically carried out in a
continuous way during operation. The programmable logic controller
is applied to realize the automatic control of centrifugal
separation and automatic flushing.
Good corrosion resistance
All parts of the centrifuge that would be in contact with material
are made of high-quality stainless steel. Drum and helical
components of the centrifuge can be welded by 304/316/316L
stainless steel, hastelloy, and titanium material, or be made by
centrifugal casting using 304 stainless steel, 2205 stainless
steel, etc. Multiple advanced abrasion proofing technologies are
applied to protecting the helical blade and the material unloading
part of drum, such as tungsten carbide coating, tungsten carbide
bead welding, cemented carbide insert, and cemented carbide
bushing, highly increasing the service life of the whole machine.
Safe and reliable
The centrifuge is equipped with multiple protections such as
overcurrent control, vibration protection and temperature
protection, to ensure safety and reliability during operation.
The machine employs the structure of profile welding, and has a
smooth and flat surface, and a beautiful appearance.

IV. Kitchen wastes water treatment system
Kitchen wastes commonly known as hogwash and also swill and pigwash, as well as
wastes (residues) from food processing and edible residue residues,
are complicated in composition, mainly oil, water, peels,
vegetables, cooked rice and noodles, fish, meat, bones, and a
mixture of waste utensils, plastics, paper towels, and the like. In
respect to chemical composition, there are starch, cellulose,
protein, lipids, and inorganic salt.

II. Kitchen wastes deoiling system
The kitchen wastes after sorting, crushing, pulping, heating, and
three-phase separation in the centrifuge are as follows:
Solid phase (waste residue) solid content % (W/W)
|≥20-25||Related to regional eating habits|
Light liquid phase (crude oil) water content % (W/W)
Heavy liquid (kitchen water) solid content % (W/W)
