Food scraps can quickly fill kitchen waste bins between collections. The HENGZE HZ-OF-30 Commercial Food Waste Composter allows kitchens to process suitable organic waste on site, reducing the amount left for storage and removal.
This stainless steel unit combines microbial treatment with controlled heating, mixing and moisture management. Operators load sorted food waste with the specified microbial culture and carrier material, then start the machine through its automatic PLC control system.
With a listed processing capacity of 30 kg, the HZ-OF-30 Food Waste Composter suits kitchens looking for a compact waste treatment unit. Its specified processing cycle is 24 hours, with a stated reduction rate of up to 90%. Actual results depend on the composition and moisture content of the waste, loading conditions and operation.
For businesses adding Food Waste Equipment to an existing kitchen, the machine offers a practical way to reduce the quantity of organic material awaiting collection.
Automatic PLC control: Runs the treatment process after loading and setup, reducing the need for continuous operator attention.
Adjustable heating: Temperature settings can be adjusted to suit the prescribed process, with high-temperature protection provided.
Timed mixing: Adjustable mixing and pause intervals help distribute material throughout the chamber. Manual control and overload protection are included.
Moisture management: Integrated dehumidification, cooling and exhaust systems support the treatment process.
Enclosed chamber: Sealed doors help limit pest access and contain odors during operation.
Compact stainless steel construction: Measures 920 × 968 × 588 mm for installation where available floor space is limited.

Model selection should take account of how much waste the kitchen generates, when it is produced and where the machine will be installed. Sites with substantial packaging, shells, large bones or other difficult materials should confirm feedstock suitability before ordering.
HENGZE can assist with model selection based on your waste quantity, material composition and available installation space. Operating instructions, remote technical guidance and spare parts support are available.
Before shipment, we can review the required electrical supply and site conditions with your team. Guidance on microbial culture, carrier material, loading and routine care helps operators prepare for daily use.
The machine is packed in an export wooden case for transport. Final packing dimensions, gross weight and delivery arrangements are confirmed with the quotation.
Please provide the destination, required quantity and any site access restrictions when requesting freight costs. Installation planning should also allow space for loading, unloading and maintenance, together with the required exhaust arrangement.
1. What does the 30 kg capacity refer to?
The specification lists a processing capacity of 30 kg and a 24-hour cycle. Share your daily waste quantity and loading schedule with HENGZE so we can confirm whether this model matches your operation.
2. What materials are needed for treatment?
The process uses suitable food waste, microbial culture and a carrier such as bran. Follow the recommended proportions and operating instructions for the supplied configuration.
3. Can all kitchen waste go into the machine?
No. Food waste must be separated from packaging, metal, glass and other non-organic items. Confirm acceptance of bones, shells and other hard materials before loading them.
4. Is the 90% reduction rate guaranteed for every load?
The stated rate is up to 90%. Results vary with the type of food waste, its moisture content and how the machine is loaded and operated.
5. Can the output be used immediately as fertilizer?
The output should be assessed before use. Further curing, testing or treatment may be necessary depending on its condition, the intended application and local requirements.
6. Does the machine need an exhaust connection?
The equipment includes an exhaust system. Confirm the outlet arrangement and ventilation requirements before choosing its installation position.
7. Does the 3.61 kW rating mean it uses 3.61 kWh every hour?
No. Rated power describes the equipment’s power rating. Actual electricity consumption depends on heater operation, processing settings, loading and cycle duration.
