Film-Covered Compost Turner – Patent Under-Film Crawler Equipment Cut Waste Gas & Labor Cost for Organic Fertilizer Plants
Why Traditional Compost Turners Cannot Match Production Standards Without Film-Covered Compost Turner
Hidden Loss & Pollution Risks Brought by Manual Film Removing Operation
It is necessary to manually lift the covering film before the traditional fermentation material pile is turned over. A large amount of ammonia gas and foul-smelling substances directly overflow and diffuse into the air. The nutrient loss of organic raw materials has become a long-term loss that the factory cannot avoid.
The film-covered compost turner can complete the entire turning process under the closed state of the film.
Solve the problem of pollution and nutrient loss due to manual film removal around the root.
Extra Labor & Supporting Equipment Increase Factory Operation Burden
Enterprises that use ordinary composting machines need to have a person in charge of collecting and laying the film.
Long-term labor costs will occupy a higher proportion of production costs.
The factory needs to purchase an odor scrubber separately to pass the environmental inspection.
This film-covered compost turner is equipped with an integrated film-collecting and film-pressing structure. Odor emissions are reduced by more than 90%, and no additional odor removal equipment is needed.
High Energy Consumption & Low Efficiency of Trough-Type Ordinary Turners
The conventional trough-type turning machine adopts a single-sided power drive structure and the overall energy consumption is 40% higher than that of the crawler-type film-covered compost turner.
The efficiency of single-tray material handling cannot match the demand for large-scale organic waste disposal.
This patented under-membrane equipment can process 3,800 cubic meters of material per hour. The total operation time of a single tank is controlled within 15 minutes, effectively shortening the fermentation cycle.
Core Technical Innovation & Independent Patent Advantage of Film-Covered Compost Turner
Exclusive National Invention Patent for Under-Film Sealed Composting Technology
Most fermentation equipment on the market still follows the process of lifting the film and turning the material.
Our self-developed film-covered compost turner breaks this old production logic.
The technology of synchronous turning and collecting film under the film has obtained a regular national invention patent.
The entire fermentation process is closed, locking heat and nutrients inside the material pile.
Promote the rapid reproduction of beneficial microorganisms and speed up the decomposition of organic materials.
Wide-Range Adaptability for Multiple Organic Waste Raw Materials
This film-covered compost turner targets large waste disposal plants.
It is perfectly suitable for use in conjunction with a complete set of organic fertilizer production lines with an annual output of more than 10,000 tons.
Livestock and poultry manure, kitchen waste, and industrial sludge can all be fed into fermentation treatment.
The indoor closed fermentation tank and outdoor composting yard can both be adapted to the two site layouts.
One device can process a variety of mixed raw materials without needing to replace the accessories.

Modular Independent Unit Function Introduction of Film-Covered Compost Turner
Heavy-Duty Crawler Walking Chassis Unit
The whole machine adopts the CA-Y4201 type reinforced track walking mechanism.
Equipped with a full hydraulic steering system, it can turn around flexibly on the spot.
The grounding pressure is controlled within 15kPa to avoid soil compaction in the composting site.
The total height of the whole machine is ≤4.8 meters, which can be placed in the interior of a regular standard factory.
Full-Layer Uniform Turning & Crushing Execution Unit
The inclined wear-resistant tooth chain plate grabs the fermented material in the lower layer of the material pile and transports it backward for mixing.
The upper rotating roller completely pulverizes the compacted and hard organic material, achieves vertical full-layer mixing of the material pile, and eliminates the problem of insufficient internal local fermentation.
The wear life of chromium nitride steel wear blade is up to 2000 hours, and the maintenance cost is reduced by 35%.
Dual-Roll Automatic Film Winding & Pressing Integrated Unit
The front and rear double roller structure is suitable for the 4.2-meter standard fermentation trough width specification.
Hydraulic automatic tension adjustment, avoid tearing and damage of film during operation.
After the rear roller group is completed, the film is pressed to reduce the loss of ammonia gas.
The entire process of collecting and laying the film is completed automatically, without the need for manual operation.
10-Inch Touch Screen Intelligent Central Control Unit
The centralized touch screen can adjust the feeding depth, walking speed, and film tension parameters.
The built-in microbial agent automatic spraying device supports timed and quantitative precise addition.
The operator does not need to climb on the fuselage to complete the adjustment of all production parameters.
The intelligent control system reduces the risk of operator error and lowers the technical threshold for workers to operate.
Six Core Production Benefits Brought by Film-Covered Crawler Compost Turner
Cut Over 70% Long-Term Manual Labor Input for Composting Workshop
All the steps of collecting the film, laying the film, and pressing the film are automatically completed by the equipment. The factory does not need to assign a person to handle the film disposal work every day.
Compared with traditional equipment, the total labor cost of the workshop has been greatly reduced. The saved labor expenses can be invested in raw material procurement and product research and development.
Over 90% Reduction of Malodorous Gas Emission to Pass EIA Easily
The whole composting operation runs under the condition that the film is completely sealed and covered. The pungent smell will not spread to the surrounding workshop and farmland environment.
No need for additional purchase of exhaust gas deodorization equipment, reducing equipment purchase investment.
It fully complies with the relevant environmental protection regulations of organic solid waste disposal.
40% Lower Energy Consumption Than Traditional Trough Compost Turners
A diesel direct drive + optimized hydraulic circulation system design scheme is adopted.
The energy loss in the power transmission process is greatly reduced.
The single tank with large processing capacity can shorten the fermentation cycle of single batch material.
The unit energy consumption of each cubic meter of fermentation material is effectively controlled.
Lock Nutrient Inside Pile to Improve Finished Organic Fertilizer Quality
The sealed film environment avoids the continuous evaporation and loss of nitrogen. Even full-layer turning accelerates the decomposition speed of organic matter.
The output of finished organic fertilizer has higher and more stable organic matter and nutrient indicators.
Enterprises can raise product prices to obtain stronger market bargaining competitiveness.
Shorten 30%-50% Whole Organic Waste Fermentation Cycle
The cover film can stabilize and maintain a constant temperature fermentation environment inside the material pile.
Appropriate temperature accelerates the reproduction speed of beneficial decomposer strains.
The crawler turner with large processing capacity can complete the full mixing of materials in a short time.
The factory does not need to expand the site to increase the total output of organic fertilizer throughout the year.
