Double helix turners and rake turners have their own advantages in the field of organic fertilizer fermentation, and their unique design and working methods bring different effects to fertilizer fermentation.
From the perspective of working principle, the double helix stacker uses rotating double helix blades to push and stir materials along the axial direction, causing them to continuously roll and mix during the forward process, achieving full contact with air and promoting fermentation. The rake type turning machine uses rake teeth installed on the rotating shaft to comb and turn materials like a comb, breaking them up and re stacking them to achieve the purpose of turning and fermenting.
In terms of fermentation effect, the double helix blades of the double helix turning machine can fully stir the material evenly, especially suitable for processing granular or small pieces of material, which can make the nutrient distribution in the material more uniform and achieve better fermentation effect. But for materials with high viscosity or fiber content, there may be incomplete mixing. The rake teeth of the rake type stacker can penetrate deep into the material pile, crush large pieces of material, and have good adaptability to various textures of materials. It can effectively promote the breathability of materials and improve fermentation efficiency.
In terms of applicability, the double helix turning machine is suitable for processing materials with good fluidity and relatively uniform texture, commonly used for fermentation of industrial organic waste residue, partially crushed crop straw, etc. The rake type stacker is more widely used for the fermentation of various organic materials, including livestock manure, garden waste, etc., especially performing well in handling materials with high moisture content and high viscosity.
In terms of operational convenience, the double helix flipping machine is relatively simple to operate, only requiring control of the rotation speed and propulsion direction of the double helix blades. But double helix blades are prone to entanglement with materials and require regular cleaning. The operation of the rake type stacker is also relatively intuitive, and the cleaning of the rake teeth is relatively easy. However, when dealing with high piled materials, it may be necessary to adjust the depth and angle of the rake teeth.
In terms of energy consumption, the double helix stacker requires relatively high power due to the rotation of the double helix blades and the propulsion of materials. The rake type stacker has relatively low energy consumption and requires less power for its rotating shaft.
In terms of investment cost, the price of the double helix flipping machine is relatively high, mainly due to its complex double helix structure and high manufacturing process requirements. The rake type turning machine has a relatively low price and high cost-effectiveness, making it suitable for most organic fertilizer production enterprises.
When choosing a double helix turner or a rake type turner, enterprises should comprehensively consider multiple factors such as material characteristics, fermentation efficiency requirements, operational convenience, and investment budget, and choose the most suitable turner equipment for their own needs.
