In the manufacture of coir pith production
M/s. Bloom and Peat Products Pvt Ltd situated in India,
maintains top-class quality control to meet the quality
requirement of European and American greenhouse cultivators.
The following are the salient features of quality
control methods that are being adopted by the company.
 |
| 1. |
Coir fibre mills which adopt the dry decortication
process of fiber, is selected for the collection
of pith. Wet Coir pith is being collected
from the coir mills directly by the company
as soon as the pith is separated from the
coir fibre. Mills which adopt the soaking
and retting of the husk is not preferred
for the collection
of coir pith. In this process we
are able to obtain fresh pith, which gives
a good volume on expansion. |
| 2. |
This process avoids contamination of seeds and other
foreign materials in the coir pith. |
| 3. |
Wet coir pith is washed with water to reduce the EC
by percolation method. The material EC is
checked by the laboratory and passed for
drying process. |
|
| 4. |
Electrical Conductivity is checked on the water extract
of the material. One part by volume of the
material is mixed with 1.5 part by volume
of Distilled water and the extract is filtered
out. This extract is measured for EC and
expressed in mS or uS. The pH of the extract
is also measured. |
| 5. |
Wet coir pith is then transported to the drying yard
of the company and dried in specially made
floors. The Coir pith is dried right under
the supervision of the company officials.
Afterr drying the moisture of the material
is checked. |
| 6. |
The dried coir pith is passed to through a vibrating
screen to remove long fibres, stones, and
sand if any. The QC department checks the
quality of the finished product for contamination
of foreign material. |
| 7. |
This cleaned material is segregated in a wind tunnel
to isolate the lighter particles from that
of the heavy particles.According to customer requirement the particles are
mixed and the homogenious material is ready
for pressing. |
| 8. |
The dried and cleaned coir pith is tested for their
electrical conductivity, moisture content
and then approved by QC for pressing. |
| 9. |
From the finished products random samples are collected
and tested periodically for its quality. If any batch of product is below standard, that lot is rejected. |
| 10. |
In
the case of briquette, Grow bag and Bale
manufacture random samples are tested for
the correctness of the weight of each product. |
