Organic compost fertilizer is a type of organic fertilizer that is made from decomposed organic matter, such as animal manure, crop residues, kitchen waste, etc. Organic compost fertilizer can improve soil fertility, enhance crop growth, and reduce environmental pollution. However, making organic compost fertilizer requires a lot of time and labor, especially for large-scale production. Therefore, many farmers and entrepreneurs are interested in setting up an organic compost fertilizer production line to produce high-quality and efficient organic compost fertilizer.
In this blog post, we will introduce the main steps and equipment of setting up a 3t per hour organic compost fertilizer production line, which can produce about 24 tons of organic compost fertilizer per day. This production line is suitable for small and medium-sized organic fertilizer plants or farms that want to produce organic compost fertilizer for their own use or for sale.
Step 1: Raw Material Collection and Pre-treatment
The first step of setting up an organic compost fertilizer production line is to collect and pre-treat the raw materials. The raw materials can be any organic waste that contains carbon and nitrogen, such as animal manure, crop residues, kitchen waste, etc. The raw materials should be sorted and crushed to reduce the size and increase the surface area for decomposition. The moisture content of the raw materials should also be adjusted to about 50-60% by adding water or drying.
Step 2: Composting and Fermentation
The second step of setting up an organic compost fertilizer production line is to compost and ferment the raw materials. Composting and fermentation are the core processes of making organic compost fertilizer, which can transform the organic matter into humus and release nutrients. There are two main methods of composting and fermentation: windrow composting and groove composting.
Windrow composting is a simple and low-cost method that involves piling the raw materials into long rows (windrows) on the ground and turning them regularly with a compost turner machine. The windrows should be about 1.5-2 meters high, 2-3 meters wide, and as long as possible. The turning frequency depends on the temperature, moisture, and oxygen levels of the compost pile, but generally once every 2-3 days. The windrow composting process usually takes about 20-30 days to complete.
Groove composting is a more advanced and efficient method that involves placing the raw materials into a series of grooves (channels) that are built on the ground or on a concrete platform. The grooves are covered with a roof to protect the compost from rain and sun. The compost is turned by a groove-type compost turner machine that moves along the rails on both sides of the groove. The groove-type compost turner machine can mix, crush, and aerate the compost more thoroughly and evenly than the windrow-type compost turner machine. The groove composting process usually takes about 15-20 days to complete.
Step 3: Screening and Granulation
The third step of setting up an organic compost fertilizer production line is to screen and granulate the finished compost. Screening is to separate the uncomposted or oversized particles from the fine and uniform compost. A rotary drum screener machine can be used to screen the compost into different sizes according to the requirements. The uncomposted or oversized particles can be returned to the composting process for further decomposition or crushing.
Granulation is to shape the screened compost into round or oval granules that are easy to store, transport, and apply. A new type organic fertilizer granulator machine can be used to granulate the compost into granules with high strength and good appearance. The new type organic fertilizer granulator machine adopts wet granulation technology that can produce granules with 100% organic matter content without adding any binders or additives. The granulation rate can reach more than 90%.
Step 4: Drying and Cooling
The fourth step of setting up an organic compost fertilizer production line is to dry and cool the granulated compost. Drying is to reduce the moisture content of the granules to about 10-15% by using a rotary drum dryer machine. Drying can prevent the granules from sticking together or molding during storage or transportation. Cooling is to lower the temperature of the granules to about room temperature by using a rotary drum cooler machine. Cooling can prevent the granules from caking or cracking due to thermal stress.
Step 5: Coating and Packing
The fifth step of setting up an organic compost fertilizer production line is to coat and pack the dried and cooled granules. Coating is to coat a layer of protective material on the surface of the granules by using a rotary drum coating machine. Coating can improve the appearance, hardness, water resistance, and anti-dust properties of the granules. Coating material can be wax, resin, oil, etc.
Packing is to pack the coated granules into bags or boxes by using an automatic packing machine. Packing can facilitate the storage, transportation, and sale of the organic compost fertilizer. The packing machine can weigh, fill, seal, and label the bags or boxes automatically and accurately.
Setting up a 3t per hour organic compost fertilizer production line is not a difficult task if you have the right equipment and guidance. The main equipment of a 3t per hour organic compost fertilizer production line includes:
– Compost turner machine (windrow-type or groove-type)
– Rotary drum screener machine
– New type organic fertilizer granulator machine
– Rotary drum dryer machine
– Rotary drum cooler machine
– Rotary drum coating machine
– Automatic packing machine
