Purchasing Guide for Manure Dewatering Machine

Manure dewatering machines play a crucial role in agricultural and farming operations by efficiently separating liquid from solid manure, reducing volume, and facilitating easier disposal or utilization of the separated components. When choosing a manure dewatering machine, it is essential to assess various factors. Tianzhong Machinery offers a comprehensive purchasing guide to help you choose the most suitable equipment from different aspects, including technical performance, brand reputation, after-sales service, and additional factors. Please keep reading for more details.

1. Technical Performance

1.1 Dewatering Efficiency

Dewatering efficiency is a crucial performance indicator for manure dewatering machines. For example, Tianzhong Machinery offers both screw press separator and sloped screen separator. The former is able to reduce the liquid content of the dewatered solid to an impressive range of 55%-60%. On the other hand, the latter machine will lower the liquid content to approximately 80%.

1.2 Processing Capacity

Assess the processing capacity of the machine to ensure it meets the volume of manure you need to handle. Tianzhong Machinery offers various model of manure dewatering machine, with a processing capacity ranging from 8 to 40 m³ per hour. You need to assess the volume of manure you need to process first and choose a suitable model.

1.3 Energy Consumption

Considering the energy consumption of the equipment is vital for reducing operational costs. Look for dewatering machines with energy-saving features to minimize energy consumption during manure processing, thereby improving economic efficiency.

1.4 Automation Level

The manure dewatering machine itself often features high levels of automation and easy operation, reducing labor cost and increasing production efficiency. If you want to improve the automation level, you can employ automatic feeding and discharging system, such as conveyor belts. Just choose a suitable machine according to the processing capacity and your budget. Below is a video showing the automatic manure processing system from our client in Norway.

1.5 Maintenance Requirements

A system with easy maintenance procedures and accessible components can reduce downtime and operational costs. Tianzhong Machinery’s manure separator features durable, stainless steel screw and screen, reducing maintenance needs. Moreover, we also offer maintainance tips and the related spare parts.

1.6 Footprint and Portability

Assess the physical footprint of the machine and ensure it fits within your available space. As you can see from the parameters table, we list the dimensions of each machine clearly for your reference. Besides, our machine is equipped with wheels for better portability. Of course, you can also install it at a fixed place.

1.7 Material Construction

Before purchasing, confirm with the supplier about the build quality and materials used in the construction of the machine. At Tianzhong Machinery, we offers standard (carbon steel and stainless steel) and updated visions (fully stainless steel). Stainless steel vision is more good-looking, durable to use, and easier to clean, but it is also more expensive. Welcome to contact us for a free quote for comparison.

2. Characteristics of Manure

It is important to consider the type of the manure you are dealing with (e.g., poultry waste, cow dung, pig manure), as well as the specific characteristic, such as moisture content and solid solid particle sizes, to ensure the selected machine is compatible with the materials you are dealing with. For example, the suitable screen opening size for cow dung is 0.75mm or 1mm; while that for chicken manure is 0.5mm or 0.75mm. In addition, for the materials with high liquid content (more than 90%), a sloped screen separator is highly recommended.

3. Brand Reputation

3.1 Manufacturer Qualifications

Choose manufacturers with relevant qualifications to ensure their products comply with local and regional standards. Review the manufacturer’s certification documents and qualification certificates to ensure the legality and reliability of the product. Tianzhong Machinery has CE certificates for dewatering machine.
