Is it suitable to use the solid liquid seperator in the chicken manure drying system ??

◆ Firstly let us make sure what is the final usage of the dried chicken manure ? 

For example, the final usage of the dried chicken manure is Organic Fertilizer and Animal Feed:  

After being dried by our chicken manure dryer, the dried chicken manure (moisture content 8%-13%) is high quality organic fertilizer for vegetable, crops, etc, and it is also very good animal feed additives for fish, pig, etc. 

◆ Analysis of the Chicken Manure Solid Liquid Separator:

As you see, the price of the poultry manure solid liquid separator is much cheaper than the chicken manure dryer, but when people want to use the fresh chicken manure to produce organic fertilizer or animal feed, why do most of the people still choose to use the more expensive chicken manure dryer machine directly? 

When we want to use the dried chicken manure as organic fertilizer and animal feed, and sell it in market, the dried chicken manure at least should be:

1- The moisture content of the dried chicken manure should be less than 13%, as the moisture content <13% is the safety storage humidity, and then the quality of the dried manure is stable. We can pack the dried manure into bag which can be stored for a long time, and we can sell it in market with good price.

2- The dried chicken manure should contains enough nutrition elements, and then it has the economic value to be used as organic fertilizer and animal feed. 

If using Sunco chicken manure drying system to dry the wet manure directly , only the water in the wet manure is evaporated into water vapour, and all the nutrition elements is still in the dried chicken manure, so the quality of the dried chicken manure is very good.

After being dried by our manure dryer directly , the nutrition content of the dried chicken manure is as follows: N: about 2.6%;  P: about 3.5%;  K; about 2.5%; Crude Protein: about 16-25%; Organic Matter: about 45%. 

As you see, if we use the poultry manure solid liquid separator to process the fresh manure such as moisture content 80% in advance, and then we will get lower moisture content such as 60% manure, and thus we will need a smaller chicken manure dryer, finally we maybe can save some money.

Then you will ask, why people do not use the much cheaper poultry manure solid liquid separator together with the smaller chicken manure dryer ?  What is the real reasons ?

As you see, the poultry manure solid liquid separator is to use screen and screw together to press and separate the liquid from the solid material of the wet manure. 

Then the problems arise:

1- After being processed by the solid liquid separator, the moisture content of chicken manure (solid materials) is still about 60%. Although some suppliers said that the moisture content can be less than 30% at most, according to our past years’ actual experience, the real story is that the moisture content usually is about 60%. 

Even if the moisture content is about 30%, it is still too wet to be packed it into bag for long time storage. If we pack the moisture content about 30% chicken manure into bag for some days, the chicken manure will harden in lumps. 

What is more, after being processed by the solid liquid separator, about 60% key nutritions of the chicken manure is in the liquid. 

In other words, after being processed by the solid liquid separator, then we use the chicken manure dryer to dry the manure, the final dried chicken manure (solid materials) only contains much less key nutritions, and the nutrition value surely is very low.  

2- After being processed by the solid liquid separator, where does the liquid go ?  There are several choice: 

-The liquid can goes into the waste water pool: 

In this way, the hated scents is still there, and the liquid (waste water) will still pollute the environment.

-The liquid can goes into digesters:

In this way, it seems ok, but do you really need to build a big digesters ? 

-The liquid can goes into farmland, Vegetable greenhouses, etc: 

In this way, your chicken farm should be very near the farmland.

In one word, if you want to use the final dried manure(solid materials) as organic fertilizer or animal feed directly, the poultry manure solid liquid separator is not suitable to be used in the chicken manure drying system. 

But if you want to use the final dried manure (solid materials) for other usages, maybe the poultry manure solid liquid separator is suitable. Anyway, it is according to your actual final usage of the dried manure.
