Kitchen waste dehydrator

Introduction to Kitchen Waste Dehydrator

A kitchen waste dewatering machine is a specialized mechanical device designed for handling kitchen waste such as leftovers, fruit peels, vegetable residues, and meat. It removes water from the waste through mechanical squeezing, centrifugation, or filtration, reducing the volume and weight of the waste and facilitating subsequent processing (such as composting, incineration, landfill, or biodegradation).

Core function

Dehydration treatment
Main function: Remove the moisture in kitchen waste and reduce its moisture content (usually from 70%-90% to 30%-50%).

Dehydration method:

Screw extrusion dewatering: By using a high-speed rotating screw shaft to squeeze the garbage and separate the moisture (suitable for high-moisture garbage).

Centrifugal dewatering: It uses the centrifugal force generated by high-speed rotation to throw out water (suitable for granular or blocky garbage).

Pressure filtration dewatering: By applying hydraulic or mechanical pressure to squeeze the garbage, water seeps out (suitable for garbage with a high fiber content).

Dehydration efficiency: Different models have different processing capacities. Generally, they can handle 50 kilograms to 5 tons of kitchen waste per hour.

(2) Reduction and pretreatment
Reduce the volume of garbage: After dehydration, the weight of garbage can be reduced by 50% to 70%, which is convenient for transportation and subsequent processing.

Improve the properties of garbage: Reduce moisture content and increase the calorific value of garbage (applicable to incineration treatment).

Convenient for composting: Dehydrated kitchen waste is more prone to fermentation, shortening the composting cycle.

Multi-functional expansion

Crushing function (for some models) : First, crush large pieces of garbage (such as bones, fruit pits), and then carry out dehydration treatment.

Deodorization function: Equipped with activated carbon filtration or biological deodorization system to reduce odor emissions.

Automation control: PLC or touch screen control, adjustable parameters such as dehydration pressure and time.

Wastewater treatment: Some models can separate wastewater, facilitating subsequent sewage treatment.

Classification and processing: It can be combined with garbage classification equipment to separate recyclables (such as plastics and metals).

Application scenarios

Household/community: Small household or community kitchen waste disposers to reduce the volume of garbage collection.

The catering industry: restaurants, hotels, canteens and other places deal with a large amount of kitchen waste.

Schools/hospitals: Centralized treatment of kitchen waste to reduce the risk of environmental pollution.

Garbage treatment plant: As a pretreatment device, it improves the efficiency of garbage treatment.

Organic fertilizer production: The dehydrated kitchen waste can be used for composting or biogas fermentation.

Advantages and characteristics

✅ Highly efficient dewatering: Quickly remove water and reduce the volume and weight of waste.
✅ Reduce waste transportation and disposal costs and decrease the need for landfill or incineration.
✅ STRONG applicability: can handle a variety of kitchen waste (containing water, oil, fiber).
✅ Reduce odor: Some models are equipped with deodorization system to improve working environment.
✅ High degree of automation: Parameters can be set, reducing human intervention.
✅ Recycling: Dehydrated waste is better suited for composting, incineration or biodegradation.

Common types

Characteristics of applicable scenarios of the type
The small household dehydrator has a low power consumption (1-3kW) for families and communities and a low processing capacity (5-50kg/h), making it suitable for small amounts of kitchen waste
The medium-sized commercial dehydrator for restaurants and canteens has a power of 5-10kW and a processing capacity of 50-200kg/h. It is suitable for commercial places
The large-scale industrial dewatering machine for garbage treatment plants has a power of over 15kW, a processing capacity of 200kg to 5 tons per hour, and can operate continuously
The screw extrusion dehydrator has a high dehydration efficiency for high-moisture waste (such as leftovers and fruit peels) and is suitable for waste with high water content
The centrifugal dewatering machine has a fast dewatering speed for granular waste (such as nuclei and bones) and is suitable for blocky or granular waste
The filter press dewatering machine can thoroughly dewater fibrous waste (such as vegetable leaves and fruit peels), and is suitable for waste with more fibers

Purchasing suggestions

Select the power based on the processing capacity: 1-3kW for households, 5-10kW for restaurants, and 15kW or more for garbage treatment plants.

Considering the characteristics of the garbage: For high-moisture garbage (such as leftovers), screw extrusion is selected; for granular garbage (if nuclear), centrifugal dewatering is chosen.

Check the dehydration rate: Generally, the moisture content should be reduced to 30%-50% after dehydration.

Pay attention to environmental protection: Choose models equipped with deodorization or wastewater treatment functions.

Considering the degree of automation: For large-scale venues, PLC-controlled models can be selected to enhance efficiency.

Summary

The kitchen waste dehydrator is an important equipment for garbage classification and treatment. It can effectively reduce the volume and weight of kitchen waste, lower environmental pollution and promote resource utilization. Its multi-functionality (such as crushing and deodorization) makes it suitable for various scenarios including households, catering, and waste treatment plants. When making a purchase, it is necessary to select the appropriate model based on the processing capacity, the characteristics of the garbage and environmental protection requirements, so as to improve the efficiency of garbage treatment and reduce the environmental burden.
