Compacity
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.

X" indicates that the heavy phase liquid is discharged by the
centripetal pump with back pressure; the overall dimensions vary
with the liquid discharging way of the centrifuge.
★ Technical features:
1. With a wide range of applications and strong compatibility, it
can handle all kinds of organic wastes, including kitchen wastes,
rubbishes after dining, vegetable market wastes, and agriculture
and forestry wastes.
2. With patented multi-stage crushing technology, it can achieve
100% crushing and utilization of organic matters to avoiding waste,
enhance utilization of organic matters, and improve economic
benefits.
3. With patented flexible limit crushing technology, it can realize
the maximum separation of inorganic substances to avoid the
inorganic substances from mixing with the organic slurry and
prevent the inorganic substances from affecting the treatment
effect of subsequent process, and to protect the normal operation
of subsequent processing equipment.
4. The treatment process is safe and environmentally friendly, and
free of pollution discharge such as wastewater and waste gas. The
wastewater can be recycled after treatment, which is economical and
energy-saving.
Our pretreatment system consists of a stainless-steel storage and
feeding system, a double-shaft shredder, a screw conveyor, a
pipe-type magnetic separator, a kitchen pulper, a belt conveyor, a
slurry tank, a transfer pump, pipes, detection instruments, etc.;
The slurry produced by the liquid collection bin of the
stainless-steel feeding system, the liquid collection bin of the
shaftless screw conveyor, and the screw extruder enters the slurry
tank. After removal of large gravel, the slurry is sent to the
heating tank with steam heating and stirring functions to be heated
to above 80°C. After 30 minutes of heat preservation, the slurry in
the heating tank is sent to the three-phase centrifuge by a screw
pump for three-phase separation of oil + water + slag.

Effect of kitchen waste slurry after treatment by
The kitchen wastes after sorting, crushing, pulping, heating, and
three-phase separation in the centrifuge are as follows:
S/N | Name |
Parameter |
Remarks |
| 01 |
Solid phase (waste residue) solid content % (W/W) | ≥20-25 | Related to regional eating habits |
| 02 |
Light liquid phase (crude oil) water content % (W/W) | ≤3~5 | |
| 03 |
Heavy liquid (kitchen water) solid content % (W/W) | ≤1~2 | |
| 04 | Heavy liquid phase (kitchen water) oil content | No macroscopic oil | |
| 05 | Oil recovery rate % | ≥95 | |
Effect after separation by the three-phase centrifuge
IV. Kitchen wastes water treatment system
After the kitchen wastes are pretreated and deoiled, and organic
matters are utilized, the remaining water must be treated
harmlessly. With the rapid development of water treatment
technology, whether it is the conventional water treatment process
or the process of anaerobic fermentation to produce biogas, the LW
series high-efficiency centrifuge (two-phase) has an indispensable
role in the treatment of remaining sludge.
★ Technical features of high efficiency LW series centrifuge
• Not only equipment manufacturer but also system engineering
service provider
With strong technical strength and rich engineering experience, we
are fully qualified for the turnkey project of the sludge
dewatering room. We are also willing to recommend the design layout
of the sludge dewatering room for owners and design institutes.
★ Humanized centrifuge configuration
1,Spiral bearing (in the drum, concealed) lubrication technology:
the lubricant is filled from the outside of the hood.
2,The hood adopts a hinged opening structure and is equipped with a
high-pressure gas strut to assist the opening.
Variable pitch technology is a relatively advanced technology in
the world. It can effectively reduce the screw pushing torque,
improve the processing capacity, and further reduce the sediment
water content.
